  英語, 研究論文（学術雑誌）, BACKGROUND: Over the last decade, novel anticancer drugs have improved the prognosis for recurrent or metastatic squamous cell carcinoma of the head and neck (RM-SCCHN). However, this has increased healthcare expenditures and placed a heavy burden on patients and society. This study investigated the frequency of use and costs of select palliative chemotherapy regimens in Japan. METHODS: From July 2021 to June 2022 in 54 healthcare facilities, we gathered data of patients diagnosed with RM-SCCHN and who had started first-line palliative chemotherapy with one of eight commonly used regimens. Patients with nasopharyngeal carcinomas were excluded. The number of patients receiving each regimen and the costs of each regimen for the first month and per year were tallied. RESULTS: The sample comprised 907 patients (674 were < 75 years old, 233 were ≥ 75 years old). 330 (36.4%) received Pembrolizumab monotherapy, and 202 (22.3%) received Nivolumab monotherapy. Over 90% of patients were treated with immune checkpoint inhibitors as monotherapy or in combination with chemotherapy. Treatment regimens' first-month costs were 612 851-849 241 Japanese yen (JPY). The cost of standard palliative chemotherapy until 2012 was about 20 000 JPY per month. The incremental cost over the past decade is approximately 600 000-800 000 JPY per month, a 30- to 40-fold increase in the cost of palliative chemotherapy for RM-SCCHN. CONCLUSION: First-line palliative chemotherapy for RM-SCCHN exceeds 600 000 JPY monthly. Over the last decade, the prognosis for RM-SCCHN has improved, but the costs of palliative chemotherapy have surged, placing a heavy burden on patients and society.

  英語, 研究論文（学術雑誌）, BACKGROUND: In a randomized phase II/III trial (JCOG1008), weekly cisplatin (40 mg/m2) was non-inferior to 3-weekly cisplatin (100 mg/m2) for postoperative high-risk head and neck cancer. We investigated how acute kidney injury (AKI), a major dose-limiting toxicity effect of cisplatin, affects overall survival (OS). METHODS: We analyzed 251 patients from JCOG1008 receiving chemoradiotherapy. AKI was defined based on AKI Network criteria (serum creatinine increase of ≥0.3 mg/dL or ≥1.5-fold [≥ stage I]) within 30 days after completing chemoradiotherapy. OS in the two arms was compared according to AKI development using the log-rank test. RESULTS: The total incidence of AKI was lower in the weekly arm than in the 3-weekly arm (38/122 [31.1%] vs. 56/129 [43.4%]). Additionally, stage II/III AKI occurred less frequently in the weekly arm than in the 3-weekly arm (8/122 [6.6%] vs. 19/129 [14.7%]). Cisplatin doses were similar in the weekly arm for patients with and without AKI (median, 238.6 mg/m2 vs. 239.2 mg/m2; p = 0.94), but lower in the 3-weekly arm for those who developed AKI (median, 276.3 mg/m2 vs. 297.4 mg/m2; p = 0.007). In the weekly arm, there was no difference in OS between patients with and without AKI (hazard ratio [HR], 1.06; 95% confidence interval [CI], 0.53 to 2.10). However, in the 3-weekly arm, patients with AKI had poorer OS than those without AKI (HR, 1.83; 95% CI, 1.04 to 3.21). CONCLUSIONS: In this supplementary analysis of JCOG1008 data, AKI impacted the OS of patients with head and neck cancer undergoing postoperative chemoradiotherapy in the 3-weekly arm but not in the weekly arm. Our results further endorse the utilization of weekly cisplatin at 40 mg/m2 in this setting.

  英語, 研究論文（学術雑誌）, OBJECTIVE: To evaluate semicircular canal function using video head impulse test (vHIT) in relapsing polychondritis (RP) patients presenting with dizziness and sensorineural hearing loss. STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Three patients with RP underwent vHIT and hearing tests. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: The gain in vestibulo-ocular reflex (VOR) and the presence of catch-up saccade were examined, and the correlation between semicircular canal dysfunction and hearing loss was investigated. RESULTS: Of the six ears, five exhibited semicircular canal dysfunction. Among these, one ear showed dysfunction in two semicircular canals, while the remaining four ears demonstrated dysfunction in all three semicircular canals. Sensorineural hearing loss, ranging from moderate to profound, was detected by pure-tone audiometry in all six ears. Furthermore, a significant correlation was observed between VOR gain in the horizontal semicircular canal (HSC) and hearing level. CONCLUSIONS: This study demonstrated semicircular canal dysfunction in RP patients presenting with dizziness and hearing loss using vHIT. Moreover, a significant correlation was found between HSC dysfunction and the severity of hearing loss. While inner ear involvement is a key clinical symptom included in the diagnostic criteria for RP, there have been few reports evaluating vestibular dysfunction, and this is the first report on the evaluation of several cases using vHIT. Accurate assessment of vestibular function by vHIT may facilitate early diagnosis and intervention in RP, potentially improving patient outcomes.
• A Case of Cochlear Implantation in a Deaf Patient With Eosinophilic Otitis Media in Whom Post-implantation Hearing Threshold Improved After Introduction of Dupilumab.

  Cureus, 16, 7, e65059, 2024年07月, ［国際誌］
  英語, 研究論文（学術雑誌）, Eosinophilic otitis media (EOM) is a rare, intractable, and chronic form of otitis media. The associated hearing loss often progresses to deafness, necessitating cochlear implantation (CI). EOM is associated with type 2 inflammatory conditions such as asthma and chronic rhinosinusitis with nasal polyps (CRSwNP). Dupilumab, a monoclonal antibody targeting the IL4Rα subunit, has shown efficacy in mitigating type 2 inflammatory diseases, including asthma and CRSwNP. Recent studies also suggest its effectiveness in treating EOM. We report a unique case of CI for EOM, in which the post-implant hearing threshold improved after the introduction of dupilumab. The patient was a 63-year-old man with a history of asthma and multiple nasal polypectomies. Eosinophils were detected in otorrhea samples from both ears, leading to an EOM diagnosis four years prior. Despite local corticosteroid therapy, his hearing gradually deteriorated. One month ago, he experienced sudden bilateral deafness and was referred to our hospital. The right tympanic membrane had a pinhole perforation but no otorrhea. CT showed a small amount of soft tissue density in the right middle ear, while the left side displayed cochlear osteolysis with soft tissue density. A right CI and myringoplasty were performed one and a half months after his visit. The cochleostomy revealed no perilymph leakage, confirming that the scala tympani was filled with granulation tissue. The electrode was inserted successfully despite the granulation, and all electrodes were placed correctly. Six months after CI, his hearing threshold with the cochlear implant remained poor at 67.5 dB. However, upon starting dupilumab therapy seven months postoperatively, his hearing threshold with the cochlear implant rapidly improved to 31.3 dB. Intraoperative findings suggested that the scala tympani was filled with granulation tissue, indicating significant cochlear inflammation due to EOM. The subsequent hearing improvement after introducing dupilumab may be attributed to the reduction or disappearance of granulation in the cochlea, allowing for effective electrical stimulation from the electrodes to the spiral ganglion. This case suggests the potential for improved postoperative hearing outcomes in CI for EOM when inflammation is effectively controlled with dupilumab.

  英語, 研究論文（学術雑誌）, OBJECTIVES: The quality of life (QOL) for patients with resolved facial nerve palsy has not been evaluated adequately. The objective of this study is to investigate QOL for patients with resolved facial nerve palsy. METHODS: Forty-seven patients with resolved facial nerve palsy were included and the patients' QOL was evaluated using the Facial Clinimetric Evaluation Scale (FaCE Scale). RESULTS: Twenty-two of the 47 patients (46.8%) with resolved facial nerve palsy showed impaired QOL, especially in terms of facial comfort and eye comfort. In 10 cases followed-up after the condition was judged to be resolved, the median scores for the FaCE scale at the time the condition was judged to be resolved and at the last visit were 65.5 and 72, respectively. The mean durations from the onset of the palsy to diagnosis of cure and to the last visit were 2.4 ± 1.6 and 4.3 ± 2.2 months, respectively. There was a significant improvement in QOL after the condition was judged to be resolved. CONCLUSION: There were discrepancies between QOL and facial movement as evaluated by physicians in patients in whom facial nerve palsy was resolved as in patients with non-cured facial nerve palsy. Patients' QOL continued to improve even after physicians judged the condition to be resolved and this result indicated that there were cases where improvement in QOL was delayed in comparison to improvement in facial movement.

  英語, 研究論文（学術雑誌）, Objectives This study aims to evaluate semicircular canal function using video head impulse test (vHIT) in patients with peripheral vestibular disorders without nystagmus. Methods Patients who underwent vHIT were enrolled in this study, and the proportion of abnormal findings on vHIT in patients without nystagmus was investigated. In addition, the results of vestibular testing were investigated in cases in which both vHIT and caloric testing were performed in patients without nystagmus. Results Forty-six patients (23.4%) of 197 patients who had no abnormal findings on the nystagmus tests, including the gaze nystagmus test, positional nystagmus test, and positioning nystagmus test, showed dysfunction in at least one semicircular canal on vHIT. The most frequent diagnosis was vestibular schwannoma (14/46, 30.4%), and cases with bilateral vestibular dysfunction were also included (12/46, 26.1%). A disorganized pattern of catch-up saccade was observed more frequently in patients with subjective symptoms of dizziness/vertigo compared to those without subjective symptoms. Although the sensitivity of vHIT was low compared to caloric testing, vHIT could detect isolated vertical canal dysfunction not detected by caloric testing. Conclusions vHIT is considered to be a useful test for patients without nystagmus, as vHIT could detect abnormalities in approximately one-quarter of patients without nystagmus. vHIT is considered to be one of the first tests to be performed following nystagmus testing, including the gaze nystagmus test, the positional nystagmus test, and the positioning nystagmus test. On the other hand, there are some cases in which vHIT shows no abnormality while caloric testing shows canal paresis. It is necessary to perform vHIT, bearing in mind that there are abnormalities that cannot be detected by vHIT alone.

  英語, 研究論文（学術雑誌）, OBJECTIVES: To evaluate pre- and post-operative semicircular canal function in patients with vestibular schwannoma (VS) by the video Head Impulse Test (vHIT). METHODS: Nineteen patients with VS who underwent surgery were enrolled in this study. The gain in vestibulo-ocular reflex (VOR) and the degree of scatter in catch-up saccades were examined pre- and post-operatively for the semicircular canals in VS patients. RESULTS: Ten of 19 cases (52.6 %) with VS were defined as demonstrating both superior vestibular nerve (SVN) and inferior vestibular nerve (IVN) impairment from the results of pre-operative vHIT. Hearing level and subjective vestibular symptoms showed significant correlations with pre-operative semicircular canal function. Compared to pre-operative vHIT results, VOR gains within 1 month after surgery were significantly reduced in all three canals; however, significant differences had disappeared in the anterior and posterior semicircular canals at 6 months after surgery. Cases of unknown origin had a significantly greater reduction in posterior semicircular canal function after surgery compared with those with disease of IVN origin. CONCLUSIONS: As vHIT could evaluate pre-operative vestibular nerve impairment, post-operative VOR gain reduction and the degree of vestibular compensation, semicircular canal function evaluated by vHIT provides a good deal of useful information regarding VS patients undergoing surgery compared to caloric testing, and vHIT should be performed pre- and post-operatively for patients with VS.

  英語, 研究論文（学術雑誌）, OBJECTIVES: Acute kidney injury (AKI) represents a major toxicity associated with cisplatin. We developed a risk prediction model for cisplatin-induced AKI in patients with postoperative high-risk head and neck cancer who received chemoradiotherapy during a randomized phase II/III trial, JCOG1008. MATERIALS AND METHODS: Two hundred and fifty-one patients received radiotherapy with weekly cisplatin at 40 mg/m2 (weekly arm) or 3-weekly cisplatin at 100 mg/m2 (3-weekly arm). AKI was defined using the AKI Network classification/staging system as increased serum creatinine of ≥0.3 mg/dL or a ≥1.5-fold increase from baseline 30 days after completing chemoradiotherapy. The Akaike information criterion was used to explore the optimal model by combining explanatory variables at registration. RESULTS: Among the 251 patients (210 men and 41 women (median age; 62 years)), 94 (37.5 %) developed cisplatin-induced AKI. The optimal cisplatin-induced AKI risk prediction model comprised four factors, including a primary site of hypopharynx/larynx (vs. oral cavity/oropharynx), 3-weekly arm (vs. weekly arm), serum albumin of ≤3.5 g/dL (vs. >3.5 g/dL) and creatinine clearance (CCr) of <90 mL/min (vs. ≥90 mL/min). The incidence of cisplatin-induced AKI rose with cumulative count of the four factors. When the cumulative count was ≥2, the positive predictive value for cisplatin-induced AKI was 50.3 %. CONCLUSIONS: We developed a risk prediction model for cisplatin-induced AKI in patients with head and neck cancer who received postoperative chemoradiotherapy using primary site, cisplatin administration method, serum albumin, and CCr. Patients with risk factors unrelated to the cisplatin administration method should adopt a weekly cisplatin regimen.

  英語, 研究論文（学術雑誌）, BACKGROUND: Transcanal endoscopic ear surgery (TEES) reportedly requires a long learning curve and may be associated with more complications and longer operative times than microscopic ear surgery (MES). In this study, we aimed to examine the usefulness and validity of TEES for ossicular chain disruption in the early stages of its introduction in our institution. METHODS: TEES was performed on 11 ears (10 with congenital ossicular chain discontinuity and 1 with traumatic ossicular chain dislocation), and MES was performed with a retroauricular incision on 18 ears (6 with congenital ossicular chain discontinuity and 12 with traumatic ossicular chain dislocation) in a tertiary referral center. Postoperative hearing results, operative times, and postoperative hospital length of stay were retrospectively reviewed. The Mann-Whitney U test and Fisher's exact test was performed to compare variables between the TEES and MES groups. Pre- and postoperative air- and bone-conduction thresholds and the air-bone gap of each group were compared using the Wilcoxon signed-rank test. The Mann-Whitney U test and Wilcoxon signed-rank was performed to compare the pre- and postoperative air-bone gaps between the diagnoses. RESULTS: No significant differences in the postoperative air-conduction thresholds, bone-conduction thresholds, air-bone gaps, or incidence of air-bone gap ≤ 20 dB were observed between the TEES and MES groups. The air-conduction thresholds and air-bone gaps of the TEES group significantly improved postoperatively. The air-conduction thresholds and air-bone gaps of the MES group also significantly improved postoperatively. No significant difference was observed in the operative times between the groups (TEES group: median, 80 min; MES group: median, 85.5 min). The TEES group had a significantly shorter postoperative hospital stay (median, 2 days) than the MES group (median, 7.5 days). CONCLUSIONS: TEES was considered appropriate for the treatment of ossicular chain disruption, even immediately after its introduction at our institution. For expert microscopic ear surgeons, ossicular chain disruption may be considered a suitable indication for the introduction of TEES.

  英語, 研究論文（学術雑誌）, BACKGROUND: Photoimmunotherapy is a treatment modality that induces targeted cell death by binding a molecular-targeted drug activated by infrared light to the tumor cells and subsequently illuminating the lesion with infrared light. For deep lesions, a needle catheter is used to puncture the tumor, and an illumination fiber (cylindrical diffuser) is inserted into the catheter lumen for internal illumination. However, it can be challenging to place the cylindrical diffusers in an appropriate position as the deep lesions cannot be often confirmed accurately during surgery. MATERIALS AND METHODS: We have developed "SlicerPIT", a planning simulation software for photoimmunotherapy. SlicerPIT allows users to place the cylindrical diffuser with its illumination range on preoperative images in 2D and 3D and export the planning data to external image-guided surgical navigation systems. We performed seven cycles of photoimmunotherapy with SlicerPIT in three patients with recurrent head and neck cancer. RESULTS: Preoperative planning for photoimmunotherapy was conducted using SlicerPIT, which could be imported into the navigation system. During the operation, we punctured the needle catheters along with the treatment plan on the navigation screen. Subsequently, intraoperative CT imaging was performed and overlaid with the preoperative treatment plan to confirm the alignment of the cylindrical diffusers as planned, followed by infrared light illumination. Postoperative imaging showed necrosis and shrinkage of the entire tumor in all cycles. CONCLUSION: SlicerPIT allows for detailed preoperative treatment planning and accurate puncture. It may be a valuable tool to improve the accuracy of photoimmunotherapy for deep lesions and improve patient outcomes.

  Japanese journal of clinical oncology, 2024年03月07日, ［国際誌］
  英語, 研究論文（学術雑誌）, Surgery remains a foundation of treatment for locally advanced squamous cell carcinoma of the head and neck. For postoperative patients at high risk of recurrence, however, surgery by itself is not enough, and improvement in survival requires postoperative treatment. Unlike the case with most other malignancies, the standard postoperative treatment for locally advanced squamous cell carcinoma of the head and neck patients with high-risk factors for recurrence is radiotherapy or chemoradiotherapy with cisplatin. However, chemoradiotherapy with cisplatin at a dose of 100 mg/m2 once every 3 weeks has raised discussion over insufficient cisplatin delivery due to high-dose-related toxicity. As a possible solution, a recent randomized trial of the JCOG1008 has proved the non-inferiority of postoperative chemoradiotherapy with weekly cisplatin at a dose of 40 mg/m2 to 3-weekly cisplatin in terms of overall survival. Here, this review article focuses on current evidence and future perspectives of postoperative treatment for locally advanced squamous cell carcinoma of the head and neck.

  英語, 研究論文（学術雑誌）, PURPOSE: To investigate the clinical significance of adaptive radiotherapy (ART) in locally advanced nasopharyngeal carcinoma treated with intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS: Eligible patients were treated with concurrent chemoradiotherapy using IMRT. Planning computed tomography in ART was performed during radiotherapy, and replanning was performed. Since ART was started in May 2011 (ART group), patients who were treated without ART up to April 2011 (non-ART group) were used as the historical control. The Kaplan-Meier method was used to calculate overall survival (OS), locoregional recurrence-free survival (LRFS), progression-free survival (PFS), and distant metastasis-free survival (DMFS). LRFS for the primary tumor (LRFS_P) and regional lymph node (LRFS_LN) were also studied for more detailed analysis. Statistical significance was evaluated using the log-rank test for survival. RESULTS: The ART group tended to have higher radiation doses. The median follow-up period was 127 months (range, 10 to 211 months) in the non-ART group and 61.5 months (range, 5 to 129 months) in the ART group. Compared to the non-ART group, the ART group showed significantly higher 5-year PFS (53.8% vs. 81.3%, p = 0.015) and LRFS (61.2% vs. 85.3%, p = 0.024), but not OS (80.7% vs. 80.8%, p = 0.941) and DMFS (84.6% vs. 92.7%, p = 0.255). Five-year LRFS_P was higher in the ART group (61.3% vs. 90.6%, p = 0.005), but LRFS_LN did not show a significant difference (91.9% vs. 96.2%, p = 0.541). CONCLUSION: Although there were differences in the patient backgrounds between the two groups, this study suggests the potential effectiveness of ART in improving locoregional control, especially in the primary tumor.

  英語, 研究論文（学術雑誌）, PURPOSE: To assess the utility of deep learning (DL)-based image reconstruction with the combination of compressed sensing (CS) denoising cycle by comparing images reconstructed by conventional CS-based method without DL in fat-suppressed (Fs)-contrast enhanced (CE) three-dimensional (3D) T1-weighted images (T1WIs) of the head and neck. MATERIALS AND METHODS: We retrospectively analyzed the cases of 39 patients who had undergone head and neck Fs-CE 3D T1WI applying reconstructions based on conventional CS and CS augmented by DL, respectively. In the qualitative assessment, we evaluated overall image quality, visualization of anatomical structures, degree of artifacts, lesion conspicuity, and lesion edge sharpness based on a five-point system. In the quantitative assessment, we calculated the signal-to-noise ratios (SNRs) of the lesion and the posterior neck muscle and the contrast-to-noise ratio (CNR) between the lesion and the adjacent muscle. RESULTS: For all items of the qualitative analysis, significantly higher scores were awarded to images with DL-based reconstruction (p < 0.001). In the quantitative analysis, DL-based reconstruction resulted in significantly higher values for both the SNR of lesions (p < 0.001) and posterior neck muscles (p < 0.001). Significantly higher CNRs were also observed in images with DL-based reconstruction (p < 0.001). CONCLUSION: DL-based image reconstruction integrating into the CS-based denoising cycle offered superior image quality compared to the conventional CS method. This technique will be useful for the assessment of patients with head and neck disease.

  英語, 研究論文（学術雑誌）, PURPOSE: To develop a convolutional neural network (CNN) model to diagnose skull-base invasion by nasopharyngeal malignancies in CT images and evaluate the model's diagnostic performance. MATERIALS AND METHODS: We divided 100 malignant nasopharyngeal tumor lesions into a training (n = 70) and a test (n = 30) dataset. Two head/neck radiologists reviewed CT and MRI images and determined the positive/negative skull-base invasion status of each case (training dataset: 29 invasion-positive and 41 invasion-negative; test dataset: 13 invasion-positive and 17 invasion-negative). Preprocessing involved extracting continuous slices of the nasopharynx and clivus. The preprocessed training dataset was used for transfer learning with Residual Neural Networks 50 to create a diagnostic CNN model, which was then tested on the preprocessed test dataset to determine the invasion status and model performance. Original CT images from the test dataset were reviewed by a radiologist with extensive head/neck imaging experience (senior reader: SR) and another less-experienced radiologist (junior reader: JR). Gradient-weighted class activation maps (Grad-CAMs) were created to visualize the explainability of the invasion status classification. RESULTS: The CNN model's diagnostic accuracy was 0.973, significantly higher than those of the two radiologists (SR: 0.838; JR: 0.595). Receiver operating characteristic curve analysis gave an area under the curve of 0.953 for the CNN model (versus 0.832 and 0.617 for SR and JR; both p < 0.05). The Grad-CAMs suggested that the invasion-negative cases were present predominantly in bone marrow, while the invasion-positive cases exhibited osteosclerosis and nasopharyngeal masses. CONCLUSIONS: This CNN technique would be useful for CT-based diagnosis of skull-base invasion by nasopharyngeal malignancies.

  英語, 研究論文（学術雑誌）, INTRODUCTION: No previous studies have evaluated the levels of neutrophil extracellular trap (NET) remnants or the importance of deoxyribonuclease (DNase) I activity based on the disease activity of otitis media with antineutrophil cytoplasmic antibody-associated vasculitis (OMAAV). The aim of this study was to explore the formation of NETs in the middle ear of patients with OMAAV during the onset and remission phases of the disease, with a particular focus on the relationships between the quantifiable levels of NET remnants and DNase I activity. METHODS: OMAAV patients were eligible for inclusion. Patients with otitis media with effusion (OME) were examined as controls. The levels of cell-free deoxyribonucleic acid (DNA), citrullinated-histone H3 (cit-H3)-DNA complex, and myeloperoxidase (MPO)-DNA complex were quantified using an enzyme-linked immunosorbent assay. DNase I activity was measured using a fluorometric method. RESULTS: The quantifiable levels of cell-free DNA, cit-H3-DNA complex, and MPO-DNA complex in the middle ear lavage of patients with OMAAV at onset were significantly higher than those in patients with OMAAV at remission and in patients with OME. DNase I activity in the patients with OMAAV at onset was significantly lower than those in patients with OMAAV at remission and OME and was negatively correlated with the level of MPO-DNA complex. CONCLUSIONS: This study suggests that NET remnants and DNase I activity may be potentially useful biomarkers for the diagnosis and disease activity of OMAAV.

  英語, 研究論文（学術雑誌）, BACKGROUND: Olfactory neuroblastoma (ONB) is a rare malignant tumor arising from the olfactory neuroepithelium. The standard of care for ONB is surgical resection; however, detailed treatment protocols vary by institution. Our treatment protocol consists of endoscopic skull base surgery (ESBS) for endoscopically resectable cases and induction chemotherapy followed by craniotomy combined with ESBS for locally advanced cases, with postoperative radiotherapy performed for all cases. Chemoradiotherapy (CRT) is performed in unresectable cases. In this study, we evaluate our treatment protocol and outcomes for ONB. METHODS: A retrospective review of patients with ONB was conducted. Outcomes included survival outcomes and perioperative data. RESULTS: Fifteen patients (53.6%) underwent ESBS, 12 (42.9%) underwent craniotomy combined with ESBS, and 1 (3.6%) received CRT. The 5- and 10-year overall survival rates for all patients were 92.9% and 82.5%, respectively, with a median follow-up period of 81 months. The 5- and 10-year disease-free survival rates were 77.3% and 70.3%, respectively, and the 5- and 10-year local control rates were 88.2% and 80.2%, respectively. Patients undergoing ESBS demonstrated a significantly shorter operating time, period from operation to ambulation, hospitalization period, and less blood loss than those undergoing craniotomy combined with ESBS. CONCLUSION: Our treatment protocol was found to afford favorable outcomes. Patients who underwent endoscopic resection showed lower complication rates and better perioperative data than those who underwent craniotomy combined with ESBS. With appropriate case selection, ESBS is considered a useful approach for ONB.

  英語, 研究論文（学術雑誌）, BACKGROUND: Whether concurrent chemotherapy with radiotherapy (CRT) is effective for elderly patients with head and neck cancer is a controversial topic. This study aimed to analyze the effectiveness of CRT vs. radiation therapy (RT) among elderly patients in Japan. METHODS: Data from the Head and Neck Cancer Registry of Japan were extracted and analyzed. Patients with locally advanced squamous cell carcinoma of the oropharynx, hypopharynx, or larynx who received definitive CRT or RT between 2011 and 2014 were included. RESULTS: CRT was administered to 78% of the 1057 patients aged ≥ 70 years and 67% of the 555 patients aged ≥ 75 years. For the patients aged ≥ 75 years, the overall survival (OS) rate was significantly better in the CRT group than in the RT group (P < 0.05), while the progression-free survival (PFS) rate was not significantly different (P > 0.05). The add-on effect of CRT was significantly poor in elderly patients (P < 0.05), and it was not a significant factor in the multivariate analysis for patients aged ≥ 75 years. After propensity score matching, there were no significant differences in the OS and PFS rates between the patients aged ≥ 70 years and those aged ≥ 75 years (all, P > 0.05). CONCLUSION: Although aggressive CRT is administered to elderly patients in Japan, its effectiveness is uncertain. Further prospective randomized trials are needed to verify whether CRT is superior to RT alone for elderly patients.

  英語, 研究論文（学術雑誌）, BACKGROUND: Tri-weekly cisplatin and radiotherapy (CDDP + RT) is a standard of care for locally advanced head and neck squamous cell carcinoma (LA-HNSCC) but is sometimes challenging to complete in older patients. Weekly CDDP + RT has shown mild toxicity compared to tri-weekly CDDP + RT for LA-HNSCC and is a promising option for older adults. We aimed to report the treatment outcomes and prognostic factors in patients with LA-HNSCC treated with weekly CDDP + RT. METHODS: We analyzed patients aged ≥ 70 years who started weekly CDDP + RT for LA-HNSCC between July 2006 and October 2022. LA-HNSCC includes cancer in the oropharynx, hypopharynx, or larynx with a clinical stage of 3 or 4 without distant metastases based on the Union for International Cancer Control staging system 8th edition. The radiation dose of 70 Gy was delivered in 35 fractions by 3-dimensional conformal radiotherapy, intensity-modulated radiotherapy, or proton beam therapy. The primary endpoint was the 3-year overall survival (OS), and the secondary endpoints were the 3-year progression-free survival (PFS) and 3-year cause-specific survival (CSS). The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used to evaluate statistical significance. A Cox proportional hazards model was used for the multivariate analysis of prognostic factors. RESULTS: The median age of the 49 patients was 72 (range: 70-78) years. The median CDDP dose was 200 (40-280) mg/ m2, and 47 patients completed scheduled radiotherapy. Forty-eight patients (98.0%) had a performance status of ≥ 1 at the initial visit. The 3-year OS, PFS, and CSS were 80.9% (95% confidence interval [CI]: 64.8-90.7), 68.3% (95% CI 51.8-81.2), and 85.0% (95% CI 68.7-93.4), respectively. In the multivariate analysis, the cumulative CDDP dose (< 200 or ≥ 200 mg/m2) was a significant factor for OS (hazard ratio: 0.29 [95% CI 0.08-0.97], p = 0.044). There was one case of early mortality. Grade 3 or higher late adverse events were observed in four patients (8.2%). CONCLUSIONS: Weekly CDDP + RT in older patients led to good survival outcomes with an acceptable rate of adverse events. CDDP should be administered at a dose of at least 200 mg/m2 in older patients. Trial registration Retrospectively registered.

  英語, 研究論文（学術雑誌）, OBJECTIVES: To investigate the utility of deep learning (DL)-based image reconstruction using a model-based approach in head and neck diffusion-weighted imaging (DWI). MATERIALS AND METHODS: We retrospectively analyzed the cases of 41 patients who underwent head/neck DWI. The DWI in 25 patients demonstrated an untreated lesion. We performed qualitative and quantitative assessments in the DWI analyses with both deep learning (DL)- and conventional parallel imaging (PI)-based reconstructions. For the qualitative assessment, we visually evaluated the overall image quality, soft tissue conspicuity, degree of artifact(s), and lesion conspicuity based on a five-point system. In the quantitative assessment, we measured the signal-to-noise ratio (SNR) of the bilateral parotid glands, submandibular gland, the posterior muscle, and the lesion. We then calculated the contrast-to-noise ratio (CNR) between the lesion and the adjacent muscle. RESULTS: Significant differences were observed in the qualitative analysis between the DWI with PI-based and DL-based reconstructions for all of the evaluation items (p < 0.001). In the quantitative analysis, significant differences in the SNR and CNR between the DWI with PI-based and DL-based reconstructions were observed for all of the evaluation items (p = 0.002 ~ p < 0.001). DISCUSSION: DL-based image reconstruction with the model-based technique effectively provided sufficient image quality in head/neck DWI.

  英語, 研究論文（学術雑誌）, BACKGROUND: Total pharyngolaryngectomy (TPL) is standard treatment for hypopharyngeal cancer. However, extensive thyroidectomy and paratracheal nodal dissection (PTND) can cause hypoparathyroidism. We sought to determine the optimum extent of resection. METHODS: We analyzed the clinicopathological information of 161 pyriform sinus cancer patients undergoing TPL from 25 Japanese institutions. Rates of recurrence and risk factors for hypoparathyroidism, as well as incidence of pathological contralateral level VI nodal metastasis and stomal recurrence, were investigated. RESULTS: The extent of thyroidectomy and nodal dissection were not independent risk factors for recurrence. Incidences of contralateral level VI nodal involvement and stomal recurrence were 1.8% and 1.2%, respectively. Patients undergoing hemithyroidectomy/ipsilateral PTND did not develop stomal recurrence and had the lowest incidence of hypoparathyroidism. Prognosis in patients without tracheostomy prior to hemithyroidectomy/ipsilateral PTND was comparable to that with more extensive resections. CONCLUSIONS: Hemithyroidectomy/ipsilateral PTND may be sufficient for pyriform sinus cancer cases without tracheostomy.
• Daily fraction dose-adjusted radiotherapy policy to avoid prolonging the overall treatment time for early glottic squamous cell carcinoma: a single-institutional retrospective study.

  Journal of radiation research, 2023年11月10日, ［国際誌］
  英語, 研究論文（学術雑誌）, The objective of this study was to determine the outcomes of radical radiotherapy for early glottic squamous cell carcinoma (EGSCC) with the policy of increasing the fraction size during radiotherapy when the overall treatment time (OTT) was expected to be prolonged. Patients diagnosed with clinical T1-2N0M0 EGSCC, who were treated with radical radiotherapy between 2008 and 2019 at Hokkaido University Hospital, were included. Patients received 66 Gy in 33 fractions for T1 disease and 70 Gy in 35 fractions for T2 disease as our standard regimen (usual group [UG]). If the OTT was expected to extend for >1 week, the dose fraction size was increased from 2.0 to 2.5 Gy from the beginning or during radiotherapy (adjusted group [AG]). At this time, we performed a statistical analysis between UG and AG. In total, 116 patients were identified, and the treatment schedules of 29 patients were adjusted. The median follow-up was 60.9 months. In the T1 group, the cumulative 5-year local failure rate was 12.0% in the AG and 15.4% in the UG, and in the T2 group, the rate was 40.7% in the AG and 25.3% in the UG. There were no significant differences between the AG and UG. Similarly, no significant differences were observed for overall survival and progression-free survival rates. Our single-institutional retrospective analysis of EGSCC patients suggested that a method of adjusting the radiotherapy schedule to increase fraction size from the beginning or during the course may be effective in maintaining treatment outcomes.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Silicon photomultiplier-based positron emission tomography/computed tomography (SiPM-PET/CT) has the superior spatial resolution to conventional PET/CT (cPET/CT). This head-to-head comparison study compared the images of physiological 18F-fluorodeoxyglucose (FDG) accumulation in small-volume structures between SiPM-PET/CT and cPET/CT in patients scanned with both modalities, and we investigated whether the thresholds that are reported to be useful for differentiating physiological accumulations from malignant lesions can also be applied to SiPM-PET/CT. METHODS: We enrolled 21 consecutive patients with head and neck malignancies who underwent whole-body FDG-PET/CT for initial staging or a follow-up evaluation (October 2020 to March 2022). After being injected with FDG, all patients underwent PET acquisition on both Vereos PET-CT and Gemini TF64 PET-CT systems (both Philips Healthcare) in random order. For each patient, the maximum standardized uptake value (SUVmax) was measured in the pituitary gland, esophagogastric junction (EGJ), adrenal glands, lumbar enlargement of the spinal cord, and epididymis. We measured the liver SUVmean and the blood pool SUVmean to calculate the target-to-liver ratio (TLR) and the target-to-blood ratio (TBR), respectively. Between-groups differences in each variable were examined by a paired t-test. We also investigated whether there were cases of target uptake greater than the reported threshold for distinguishing pathological from physiological accumulations. RESULTS: Data were available for 19 patients. Ten patients were in Group 1, i.e., the patients who underwent SiPM-PET first, and the remaining nine patients who underwent cPET first were in Group 2. In the SiPM-PET results, the SUVmax of all targets was significantly higher than that obtained by cPET in all patients, and this tendency was also observed when the patients were divided into Groups 1/2. The TLRs of all targets were significantly higher in SiPM-PET than in cPET in all patients, and SiPM-PET also showed significantly higher TBRs for all targets except the EGJ (p = 0.052). CONCLUSIONS: The physiological uptake in the small structures studied herein showed high accumulation on SiPM-PET. Our results also suggest that the thresholds reported for cPET to distinguish pathological accumulations likely lead to false-positive findings in SIPM-PET evaluations.

  英語, 研究論文（学術雑誌）, BACKGROUND: Chemoradiotherapy (CRT) with concurrent cisplatin is the standard of care as a nonsurgical definitive treatment for patients with locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). However, CRT is associated with increased severe late adverse events, including swallowing dysfunction, xerostomia, ototoxicity, and hypothyroidism. Few strategies aimed at less invasive CRT without compromising treatment outcomes have been successful. The purpose of this study is to confirm the non-inferiority of reduced dose prophylactic radiation with 40 Gy compared to standard dose prophylactic radiation with 56 Gy in terms of the time to treatment failure (TTF) among patients with clinical stage III-IVB LA-SCCHN. METHODS: This study is a multicenter, two-arm, open-label, randomized phase III trial. Patients with LA-SCCHN excluding p16 positive oropharynx cancer are randomized to the standard arm or experimental arm. A total dose of 70 Gy for tumors with concurrent cisplatin at 100 mg/m2 are administered in both arms. For prophylactic field, patients in the standard arm receive a total dose of 56 Gy in 35 fractions for 7 weeks using simultaneous integrated boost (SIB56) and those in the experimental arm receive 40 Gy in 20 fractions using two-step methods for 4 weeks (2-step40). A total of 400 patients will be enrolled from 52 Japanese institutions within 5 years. The primary endpoint is TTF, and the secondary endpoints are overall survival, complete response rate, progression-free survival, locoregional relapse-free survival, acute and late adverse events, quality of life score, and swallowing function score. DISCUSSION: If the experimental arm is non-inferior to the standard arm in terms of TTF and superior on the safety endpoints, the 2-step40 procedure is the more useful treatment than SIB56 for definitive CRT. TRIAL REGISTRATION: This trial has been registered in the Japan Registry of Clinical Trials as jRCTs031210100 ( https://jrct.niph.go.jp/latest-detail/jRCTs031210100 ). Date of Registration: May 2021.

  英語, 研究論文（学術雑誌）, OBJECTIVE: We report two cases of petrous apex cholesterol granuloma (PACG) treated with an endoscopic transsphenoidal approach. Vestibular functions of the two patients were evaluated quantitatively by video Head Impulse Test (vHIT) and/or vestibular evoked myogenic potentials (VEMPs). PATIENTS: Two patients with PACG who experienced episodes of dizziness are presented. INTERVENTION: An endoscopic transsphenoidal approach to PACG. MAIN OUTCOME MEASURE: The preoperative and postoperative vestibular functions as evaluated by vHIT and VEMP. RESULTS: Two cases of PACG were treated by a transsphenoidal approach. The internal auditory canal was compressed by the PACG in both cases. The patients both experienced episodes of dizziness before surgery and preoperative vestibular testing including vHIT and VEMP indicated dysfunction of vestibular nerves. After surgery, their symptoms were completely resolved, and the vestibular testing results were improved. CONCLUSIONS: This article is noteworthy for being the first to publish quantitative vestibular function testing for patients with PACG with vestibular dysfunction. PACG may show various symptoms, with dizziness being one of the most common symptoms. In cases in which the internal auditory canal is compressed by the PACG, vestibular functions should be evaluated by vHIT and VEMP. In the present cases, dizziness was found to be resolved by surgery to release the compression on internal auditory canal. Based on the present cases, the transsphenoidal approach is considered to be both safe and effective.

  英語, 研究論文（学術雑誌）, BACKGROUND: Lenvatinib is widely used to treat unresectable and advanced thyroid carcinomas. We aimed to determine whether 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) performed 1 week after lenvatinib treatment initiation could predict treatment outcomes. RESULTS: This was a prospective, nonrandomised, multicentre study. Patients with pathologically confirmed differentiated thyroid carcinoma (DTC) and lesions refractory to radioiodine treatment were eligible for inclusion. Patients were treated with 24 mg lenvatinib as the initial dose and underwent PET/CT examination 1 week after treatment initiation. Contrast-enhanced CT was scheduled at least 4 weeks later as the gold standard for evaluation. The primary endpoint was to evaluate the discrimination power of maximum standardised uptake value (SUVmax) obtained by PET/CT compared to that obtained by contrast-enhanced CT. Evaluation was performed using the area under the receiver operating characteristic (ROC-AUC) curve. Twenty-one patients were included in this analysis. Receiver operating characteristic (ROC) curve analysis yielded an AUC of 0.714 for SUVmax after 1 week of lenvatinib treatment. The best cut-off value for the treatment response for SUVmax was 15.211. The sensitivity and specificity of this cut-off value were 0.583 and 0.857, respectively. The median progression-free survival was 26.3 months in patients with an under-cut-off value and 19.7 months in patients with an over-cut-off value (P = 0.078). CONCLUSIONS: The therapeutic effects of lenvatinib were detected earlier than those of CT because of decreased FDG uptake on PET/CT. PET/CT examination 1 week after the initiation of lenvatinib treatment may predict treatment outcomes in patients with DTC. TRIAL REGISTRATION: This trial was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry (number UMIN000022592) on 6 June, 2016.

  英語, 研究論文（学術雑誌）, BACKGROUND: The standard of care for sinonasal mucosal melanoma is surgery and postoperative radiotherapy (PORT). Our treatment strategy comprises endoscopic resection and PORT. We performed combined endoscopic and open resection or applied an external approach alone when sufficient resection was difficult to achieve endoscopically. The objective of this study was to evaluate the validity of our treatment strategy. METHODS: We assessed 30 patients with sinonasal mucosal melanoma who underwent definitive therapy between January 2002 and April 2021, and conducted a retrospective analysis. The median follow-up period was 2.2 years. The primary endpoint was overall survival. The Kaplan-Meier method was used for the calculation of survival rates, the cumulative incidence of distant metastasis, and local recurrence. RESULTS: Twenty-eight patients underwent surgery. The other two patients were treated by definitive proton beam therapy. Twenty-one of 28 (75%) patients underwent resection by endoscopic approach alone. Postoperative radiotherapy was performed for all 28 patients who underwent surgery. Twenty-one patients (70%) experienced recurrence during the observation period. Overall, distant metastasis was observed in 19 patients. Twelve patients died during the observation period, with 10 of the 12 patients (83%) dying of distant metastasis. The overall survival rate at 2 and 5 years was 70% and 46%, respectively. The cumulative incidence rate of distant metastasis at 2 years was 63%, while the 2-year cumulative incidence rate of local recurrence was 6.7%. CONCLUSION: The local disease was controlled by our treatment strategy. To improve treatment outcomes, control of the distant metastasis is needed.

  英語, 研究論文（学術雑誌）, BACKGROUND: Superselective intra-arterial infusion of cisplatin and concomitant radiotherapy (RADPLAT) is a very promising treatment modality for locally advanced head and neck squamous cell carcinoma. However, there are some concerns regarding its potential for the control of neck lymph node metastasis. The objective of this study was to investigate whether RADPLAT provided inferior regional control compared to intravenous chemoradiotherapy (IV-CRT). METHODS: A total of 172 patients with neck lymph node metastases, 66 of whom underwent RADPLAT and 106 IV-CRT, were enrolled in this study. We retrospectively compared regional control rates between RADPLAT and IV-CRT. Furthermore, to adjust for differences in factors related to patient background between the groups, we conducted inverse probability weighting (IPW) analysis using the propensity score. RESULTS: A comparison between the two groups revealed that the regional control rates were almost equal under unadjusted conditions; however, after adjustment by IPW analysis, the RADPLAT group had a relatively better regional control rate than did the IV-CRT group (1 year regional control rate: 86.6% vs. 79.4%). In addition, the analysis of relative risk factors for regional control in the RADPLAT group showed that the absence of intra-arterial cisplatin infusion into metastatic lymph nodes was the only independent risk factor (Hazard ratio: 4.23, p = 0.04). CONCLUSION: This study showed that the regional control rate in patients treated with RADPLAT was noninferior to that for IV-CRT. Locally advanced head and neck cancers is a good indication for RADPLAT, even if the patients have neck lymph node metastases.

  英語, 研究論文（学術雑誌）, BACKGROUND: Tripartite motif-containing 27 (TRIM27) has been implicated in the progression of various cancers. However, the role of TRIM27 in sinonasal mucosal melanoma (SNMM) remains poorly understood. MATERIALS & METHODS: We retrospectively examined 28 patients with SNMM treated with between 2003 and 2021. We undertook immunohistochemical analysis of TRIM27, Ki-67, and p-Akt1 expression in SNMM tissues. We also investigated the relationship between TRIM27 expression and clinical characteristics, prognosis, Ki-67 as a tumor growth potential marker, and p-Akt1 as one of the prognostic factors in mucosal melanoma. RESULTS: TRIM27 expression was significantly higher in T4 disease than in T3 disease and was higher in stage IV than in stage III. Patients with high-TRIM27 SNMM had a significantly poorer prognosis in terms of overall survival (OS) and disease-free survival.There was also a significantly higher rate of distant metastasis. Univariate analysis for OS revealed that TRIM27 and T classification were significant poor prognostic factors. In addition, the Ki-67 positive score and the p-Akt1 total staining score were significantly higher in the high-TRIM27 group than in the low-TRIM27 group. CONCLUSIONS: High TRIM27 expression in SNMM was associated with advanced T classification, poor prognosis and distant metastasis. We suggest that TRIM27 has potential as a novel biomarker for prognosis in SNMM.

  英語, 研究論文（学術雑誌）, INTRODUCTION: Surgeons' mental workload during endoscopic sinus surgery (ESS) has not been fully evaluated. The assessment was challenging due to the great diversity of each patient's anatomy and the consequence variety of surgical difficulties. In this study, we examined the mental workload of surgeons with various surgical skill levels during ESS under the standardized condition provided by novel-designed 3D sinus models. MATERIALS AND METHODS: Forty-seven participants performed a high-fidelity ESS simulation with 3D-printed sinus models. Surgeons' mental workload was assessed with the national aeronautics and space administration-task load index (NASA-TLX). Associations between the total and subscales score of NASA-TLX and surgical skill index, including the board certification status, the number of experienced ESS cases, and the objective structured assessment of technical skills (OSATS), were analyzed. In addition, 10 registrars repeated the simulation surgery, and their NASA-TLX score was compared before and after the repetitive training. RESULTS: The total NASA-TLX score was significantly associated with OSATS score (p = 0.0001). Primary component analysis classified the surgeons' mental burden into three different categories: (1) the skill-level-dependent factors (temporal demand, effort, and performance), (2) the skill-level-independent factors (mental and physical demand), and (3) frustration. After the repetitive training, the skill-level-dependent factors were alleviated (temporal demand; z = -2.3664, p = 0.0091, effort; z = -2.1704, p = 0.0346, and performance; z = -2.5992, p = 0.0017), the independent factors were increased (mental demand; z = -2.5992, p = 0.0023 and physical demand; z = -2.2509, p = 0.0213), and frustration did not change (p = 0.3625). CONCLUSION: Some of the mental workload during ESS is associated with surgical skill level and alleviated with repetitive training. However, other aspects remain a burden or could worsen even when surgeons have gained surgical experience. Routine assessment of registrars' mental burdens would be necessary during surgical training to sustain their mental health.

  英語, 研究論文（学術雑誌）, INTRODUCTION: Sequential boost intensity-modulated radiotherapy (SQB-IMRT) uses two different planning CTs (pCTs) and treatment plans. SQB-IMRT is a form of adaptive radiotherapy that allows for responses to changes in the shape of the tumour and organs at risk (OAR). On the other hand, dose accumulation with the two plans can be difficult to evaluate. The purpose of this study was to analyse patterns of loco-regional failure using deformable image registration (DIR) in hypopharyngeal cancer patients treated with SQB-IMRT. METHODS: Between 2013 and 2019, 102 patients with hypopharyngeal cancer were treated with definitive SQB-IMRT at our institution. Dose accumulation with the 1st and 2nd plans was performed, and the dose to the loco-regional recurrent tumour volume was calculated using the DIR workflow. Failure was classified as follows: (i) in-field (≥95% of the recurrent tumour volume received 95% of the prescribed dose); (ii) marginal (20-95%); or (iii) out-of-field (<20%). RESULTS: After a median follow-up period of 25 months, loco-regional failure occurred in 34 patients. Dose-volume histogram analysis showed that all loco-regional failures occurred in the field within 95% of the prescribed dose, with no marginal or out-of-field recurrences observed. CONCLUSION: The dosimetric analysis using DIR showed that all loco-regional failures were within the high-dose region. More aggressive treatment may be required for gross tumours.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Esophageal cancer is the most common second primary cancer (SPC) in patients with head and neck cancer (HNC). Esophageal SPC has a negative impact on survival. Elevated mean corpuscular volume (MCV) is an accepted predictor of esophageal cancer risk. The aim of this study was to elucidate the usefulness of elevated MCV as an indicator of a high risk for esophageal SPC. METHODS: We retrospectively reviewed the medical records of patients with oropharyngeal, hypopharyngeal, and laryngeal squamous cell carcinoma who underwent chemoradiotherapy between 2003 and 2012. We excluded patients younger than 20 years or who had received treatment for esophageal cancer and who had a histologically unproven lesion. Patients were divided into two groups according to their MCV. The cut-off for MCV was defined by receiver operating characteristics curve analysis. The primary endpoint was the cumulative incidence of esophageal SPC. RESULTS: A total of 295 patients were included. The median follow-up period for surviving patients was 7.4 years and the optimal cut-off point was 99.0 fL. One hundred ninety-five patients (66%) had an MCV < 99.0 fL and 100 (34%) had an MCV ≥ 99.0 fL. The 5-year cumulative incidence in patients with an MCV < 99.0 fL and ≥ 99.0 fL was 8.7% and 27%, respectively. In the multivariate analysis, an MCV ≥ 99.0 fL (HR=2.2; 95%CI, 1.1-4.2) was an independent risk factor. CONCLUSION: MCV ≥ 99.0 fL was found to be a risk factor for esophageal SPC. We, therefore, recommend that patients with an MCV ≥ 99.0 fL should undergo intensive monitoring.

  英語, 研究論文（学術雑誌）, BACKGROUND: In nasal or sinonasal tumors, orbital invasion beyond periorbita by the tumor is one of the important criteria in the selection of the surgical procedure. We investigated the usefulness of the convolutional neural network (CNN)-based deep learning technique for the diagnosis of orbital invasion, using computed tomography (CT) images. METHODS: A total of 168 lesions with malignant nasal or sinonasal tumors were divided into a training dataset (n = 119) and a test dataset (n = 49). The final diagnosis (invasion-positive or -negative) was determined by experienced radiologists who carefully reviewed all of the CT images. In a CNN-based deep learning analysis, a slice of the square target region that included the orbital bone wall was extracted and fed into a deep-learning training session to create a diagnostic model using transfer learning with the Visual Geometry Group 16 (VGG16) model. The test dataset was subsequently tested in CNN-based diagnostic models and by two other radiologists who were not specialized in head and neck radiology. At approx. 2 months after the first reading session, two radiologists again reviewed all of the images in the test dataset, referring to the diagnoses provided by the trained CNN-based diagnostic model. RESULTS: The diagnostic accuracy was 0.92 by the CNN-based diagnostic models, whereas the diagnostic accuracies by the two radiologists at the first reading session were 0.49 and 0.45, respectively. In the second reading session by two radiologists (diagnosing with the assistance by the CNN-based diagnostic model), marked elevations of the diagnostic accuracy were observed (0.94 and 1.00, respectively). CONCLUSION: The CNN-based deep learning technique can be a useful support tool in assessing the presence of orbital invasion on CT images, especially for non-specialized radiologists.

  英語, 研究論文（学術雑誌）, BACKGROUND: External auditory canal squamous cell carcinoma (EACSCC) is a rare form of malignant tumor. Due to the extremely limited understanding of the genomic landscape in EACSCC, the association between gene mutations and clinicopathologic features remains unclear. This study aimed to explore somatic gene mutations associated with the clinicopathological features in patients with EACSCC, and to identify the candidate gene mutations for predicting survival outcome in EACSCC. METHODS: Twenty-two tissue samples obtained from patients with EACSCC were analyzed for genetic mutations based on targeted next-generation sequencing and genetic expression based on IHC staining to investigate the driver of tumorigenesis and/or the candidates of genes for predicting clinical outcome in EACSCC. RESULTS: Gene alterations were most frequently observed in TP53 (59.1%), followed by CREBBP (9.1%). TP53 mutations showed significant correlation with T classification (P = 0.027) and p53 expression phenotype (P < 0.001). The 5-year overall survival (OS) rates for EACSCC patients with TP53 mutations and wild-type TP53 were 45.0% and 75.0%, respectively. Multivariable analysis using the Cox proportional hazards model demonstrated that TP53 mutations were independent predictors of OS rates for EACSCC patients (P = 0.007). CONCLUSION: This study has suggested that TP53 mutations have potential for use as a biomarker for identifying individuals at high risk of developing tumors and for predicting survival outcome in EACSCC. IHC staining for p53 might play a useful role as screening tool for detecting TP53 mutations in patients with EACSCC.

  英語, 研究論文（学術雑誌）, BACKGROUND: Radiotherapy plus cetuximab (bioradiotherapy: BRT) is a standard option in the treatment of locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN). Published data on its safety and efficacy in real-world settings is limited. Here, we conducted a prospective multi-institutional observational study to evaluate clinical outcomes of BRT in patients with LA-SCCHN. METHODS: We analyzed real-world data of all patients who underwent BRT from 2013 to 2016. The primary endpoint was 1-year progression-free survival (PFS). Secondary endpoints were 1-year locoregional PFS (LPFS), treatment completion rate (TCR), and adverse events (AEs). RESULTS: A total of 171 patients with a minimum 1-year follow-up were analyzed. Median age was 67 (36-85) years, and 37 patients (21.6%) were aged 75 years or older. 1-year PFS and LPFS were 51.5 and 56.1%, respectively. N stage (p = 0.049) was significantly associated with PFS. TCR was 77.2%. Cetuximab was definitively discontinued in 30 patients (17.5%), in 15 cases due to severe mucositis. N stage, T stage, and comorbidity were significantly associated with TCR. Major AEs of grade 3 or higher were pharyngeal mucositis (48.5%), radiation dermatitis (45.6%), and oral mucositis (40.4%). Pneumonitis was observed in 12 patients (7.0%); 6 cases (3.5%) were grades 3-4 and 2 (1.2%) were grade 5. CONCLUSION: As a result of the large number of elderly patients in clinical practice, toxicity reduced TCR. BRT-induced pneumonitis, which is sometimes fatal, was found to be more frequent than with chemotherapy plus cetuximab.

  英語, 研究論文（学術雑誌）, Background: The purpose of this study was to find a utility of a newly developed 3D-printed sinus model and to evaluate the educational benefit of simulation training with the models for functional endoscopic sinus surgery (FESS). Material and methods: Forty-seven otolaryngologists were categorized as experts (board-certified physicians with ≥200 experiences of FESS, n = 9), intermediates (board-certified physicians with <200 experiences of FESS, n = 19), and novices (registrars, n = 19). They performed FESS simulation training on 3D-printed models manufactured from DICOM images of computed tomography (CT) scan of real patients. Their surgical performance was assessed with the objective structured assessment of technical skills (OSATS) score and dissection quality evaluated radiologically with a postdissection CT scan. First we evaluated the face, content, and constructive values. Second we evaluated the educational benefit of the training. Ten novices underwent training (training group) and their outcomes were compared to the remaining novices without training (control group). The training group performed cadaveric FESS surgeries before and after the repetitive training. Results: The feedback from experts revealed high face and content value of the 3D-printed models. Experts, intermediates, and novices demonstrated statistical differences in their OSATS scores (74.7 ± 3.6, 58.3 ± 10.1, and 43.1 ± 11.1, respectively, p < .001), and dissection quality (81.1 ± 13.1, 93.7 ± 15.1, and 126.4 ± 25.2, respectively, p < .001). The training group improved their OSATS score (41.1 ± 8.0 to 61.1 ± 6.9, p < .001) and dissection quality (122.1 ± 22.2 to 90.9 ± 10.3, p = .013), while the control group not. After training, 80% of novices with no prior FESS experiences completed surgeries on cadaver sinuses. Conclusion: Repeated training using the models revealed an initial learning curve in novices, which was confirmed in cadaveric mock FESS surgeries. Level of evidence: N/A.

  英語, 研究論文（学術雑誌）, Background: In head and neck cancers, histopathological information is important for the determination of the tumor characteristics and for predicting the prognosis. The aim of this study was to assess the utility of diffusion-weighted T2 (DW-T2) mapping for the evaluation of tumor histological grade in patients with head and neck squamous cell carcinoma (SCC). Methods: The cases of 41 patients with head and neck SCC (21 well/moderately and 17 poorly differentiated SCC) were retrospectively analyzed. All patients received MR scanning using a 3-Tesla MR unit. The conventional T2 value, DW-T2 value, ratio of DW-T2 value to conventional T2 value, and apparent diffusion coefficient (ADC) were calculated using signal information from the DW-T2 mapping sequence with a manually placed region of interest (ROI). Results: ADC values in the poorly differentiated SCC group were significantly lower than those in the moderately/well differentiated SCC group (P<0.05). The ratio of DW-T2 value to conventional T2 value was also significantly different between poorly and moderately/well differentiated SCC groups (P<0.01). Receiver operating characteristic (ROC) curve analysis of ADC values showed a sensitivity of 0.76, specificity of 0.67, positive predictive value (PPV) of 0.62, negative predictive value (NPV) of 0.8, accuracy of 0.71 and area under the curve (AUC) of 0.73, whereas the ROC curve analysis of the ratio of DW-T2 value to conventional T2 value showed a sensitivity of 0.76, specificity of 0.83, PPV of 0.76, NPV of 0.83, accuracy of 0.8 and AUC of 0.82. Conclusions: DW-T2 mapping might be useful as supportive information for the determination of tumor histological grade in patients with head and neck SCC.

  英語, 研究論文（学術雑誌）, OBJECTIVE: The localization pattern of metastatic sentinel lymph node (SN) and non-SNs and pathologic analysis of metastatic lymph nodes in SN lymphatic basin dissection (SLBD) were investigated in patients with cT2/T3cN0 oral squamous cell carcinoma (OSCC). METHODS: This prospective multicenter trial involved 10 institutions nationwide in Japan. A total of 57 patients were enrolled. The lateral neck was divided into 5 lymphatic basins. The lymphatic basin containing SNs was defined as the SN lymphatic basin. All patients underwent SLBD with backup selective neck dissection (I-III) combined with primary tumor removal. When SNs were found outside of levels I-III, including in the contralateral neck, SLBD was performed by removing the compartments containing SNs separately. SN metastasis was classified as isolated tumor cells (ITCs), micrometastasis, or macrometastasis. ITCs are defined as a lesion no larger than 0.2 mm in largest dimension and are classified as pN0. RESULTS: SN metastasis was observed in 22 cases. All metastatic lymph nodes, including false-negative cases, were detected in the SN lymphatic basin. Isolated tumor cells in the SNs did not affect prognosis, whereas micrometastasis tended to have poor prognosis. After adjusting for other risk factors, a positive SN remained a significant predictor of poor 5-year overall survival in pT2-4 OSCC. CONCLUSION: SLBD for intraoperative SN biopsy is a sufficient therapeutic procedure and is valuable for determining pathologic nodal stage in OSCC. SN positivity was demonstrated to be an independent predictor of poor prognosis in patients with pT2-4 disease undergoing SLBD with backup selective neck dissection (I-III).

  英語, 研究論文（学術雑誌）, The aim of this study was to investigate the utility of amide proton transfer (APT) imaging for the determination of human papillomavirus (HPV) status in patients with oropharyngeal squamous cell carcinoma (SCC). Thirty-one patients with oropharyngeal SCC were retrospectively evaluated. All patients underwent amide proton transfer imaging using a 3T magnetic resonance (MR) unit. Patients were divided into HPV-positive and -negative groups depending on the pathological findings in their primary tumor. In APT imaging, the primary tumor was delineated with a polygonal region of interest (ROI). Signal information in the ROI was used to calculate the mean, standard deviation (SD) and coefficient of variant (CV) of the APT signals (APT mean, APT SD, and APT CV, respectively). The value of APT CV in the HPV-positive group (0.43 ± 0.04) was significantly lower than that in the HPV-negative group (0.48 ± 0.04) (P = .01). There was no significant difference in APT mean (P = .82) or APT SD (P = .13) between the HPV-positive and -negative groups. Receiver operating characteristic (ROC) curve analysis of APT CV had a sensitivity of 0.75, specificity of 0.8, positive predictive value of 0.75, negative predictive value of 0.8, accuracy of 0.77 and area under the curve (AUC) of 0.8. The APT signal in the HPV-negative group was considered heterogeneous compared to the HPV-positive group. This information might be useful for the determination of HPV status in patients with oropharyngeal SCC.

  英語, 研究論文（学術雑誌）, OBJECTIVES: To evaluate semicircular canal function in patients with labyrinthine fistula (LF) due to cholesteatoma by the video Head Impulse Test (vHIT). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Ten patients with LF due to cholesteatoma and six without LF underwent vestibular examination. INTERVENTION: Diagnostic. MAIN OUTCOME MEASURES: The gain in vestibulo-ocular reflex (VOR) and the presence of catch-up saccade were examined for the semicircular canals in patients with LF. RESULTS: Seven of 10 cases (70.0%) in the fistula group were judged to have semicircular canal dysfunction based on preoperative evaluation. VOR gains in the patients with LF were significantly lower than those in the patients without LF. VOR gain decreased significantly in accordance with the severity of the LF. The postoperative VOR gain more than 6 months after surgery was significantly improved compared with the preoperative VOR gain. CONCLUSIONS: The vHIT is thought to be the most suitable method for evaluating semicircular canal function in patients with LF due to cholesteatoma as it is not influenced by middle ear pathology and can evaluate the function of the vertical canals. The vHIT could predict whether a LF is present or not before surgery, and the vHIT is essential for surgery for patients with LF.

  英語, Lateral semicircular canal (LSCC) malformations represent one of the most common types of inner ear malformation. As many cases of LSCC malformations are asymptomatic, detailed vestibular functions in such cases remain unclear. We present a case with bilateral LSCC malformations for whom the function of each vestibular organ was evaluated by caloric testing, video Head Impulse Test (vHIT) and vestibular evoked myogenic potentials (VEMP). Caloric testing showed canal paresis of the left side, whereas vHIT showed bilateral normal semicircular canal function. The results of VEMP indicated left saccular dysfunction. Discrepancies in caloric testing and vHIT results were observed and these discrepancies are thought to be due to endolymphatic hydrops rather than vestibular hypofunction, similar to that in Meniere disease.

  英語, 研究論文（学術雑誌）, Salivary gland malignancies are rare neoplasms that have a broad histological spectrum and a variety of biologic behaviors. Salivary gland malignancies are known as chemo-resistant tumors, which render optimal treatment challenging. This review summarizes the role of systemic therapy for salivary gland malignancies. To date, the advantage of adding concurrent chemotherapy has remained undefined for both postoperative and inoperable locally advanced salivary gland malignancy patients undergoing radiotherapy. For recurrent/metastatic disease, local and/or systemic treatment options should be discussed in a multidisciplinary setting with consideration to both patient needs and tumor factors. For symptomatic patients or those who may compromise organ function, palliative systemic therapy can be a reasonable option based on the results of phase II studies. Platinum combination regimens as first-line therapy have been widely accepted. Personalized therapies have become established options, particularly for androgen receptor-positive, HER2-positive and NTRK fusion-positive salivary gland malignancies (i.e. androgen receptor and HER2 in salivary duct carcinoma and NTRK3 in secretory carcinoma). For patients with adenoid cystic carcinoma, multi-targeted tyrosine kinase inhibitors have also been developed. Anti-PD1 checkpoint inhibitors have shown limited activity to date. Investigation of active systemic treatments for salivary gland malignancy remains a significant unmet need. Future directions might include a more comprehensive genomic screening approach (usually next-generation sequencing-based) and combination strategies using immune checkpoint inhibitors. These are rare malignancies that require ongoing effort in the conduct of high-quality clinical trials.

  英語, 研究論文（学術雑誌）, It was not until around 2000 that human papillomavirus-related oropharyngeal carcinoma was recognized as carcinoma with clinical presentations different from nonrelated head and neck carcinoma. Twenty years after and with the revision of the tumor-node-metastasis classification in 2017, various clinical trials focused on human papillomavirus-related oropharyngeal carcinoma to improve the prognosis and quality of life of patients with this disease. However, the incidence of human papillomavirus-related cancers is increasing, which is expected to be particularly prominent in Japan, where human papillomavirus vaccination is not widely available. In this review, we describe the current status of clinical trials (mainly focused on initial surgery and radiation dose reduction) for, primary and secondary prevention of, and the present status of human papillomavirus-related oropharyngeal carcinoma in Japan.

  英語, 研究論文（学術雑誌）, INTRODUCTION: Patients with head and neck cancer (HNC) are usually confronted with functional changes due to the malignancy itself or its treatment. These factors typically affect important structures involved in speech, breathing, chewing, swallowing, and saliva production. Consequently, the intake of food will be limited, which further contributes to loss of body weight and muscle mass, anorexia, malnutrition, fatigue, and anemia. This multifactorial condition can ultimately lead to cancer cachexia syndrome. This study aims to examine the treatment of cachexia in HNC patients. METHODS: We systematically searched OvidMedline, PubMed, Scopus, and Web of Science for articles examining the treatment of cachexia in HNC. RESULTS: A total of nine studies were found, and these suggested interventions including nutritional, pharmacologic, therapeutic exercise, and multimodal approaches. The nutritional intervention includes essential components such as dietary counseling, oral nutritional supplements, and medical nutritional support. Individualized nutritional interventions include oral, enteral (feeding tubes i.e., percutaneous endoscopic gastrostomy [PEG], nasogastric tube [NGT]) and parenteral nutrition. The pharmacologic interventions aim at increasing the appetite and weight of cachectic patients. Therapeutic exercise and increased physical activity can help to enhance the synthesis of muscle protein, reducing inflammation and the catabolic effects of cachexia syndrome. CONCLUSION: Owing to the multifactorial nature of this syndrome, it is expected that the management approach should be multi-interventional. Early implementation of these interventions may help to improve survival and quality of health and life of cachectic HNC patients.

  英語, 研究論文（学術雑誌）, PURPOSE: The standard treatment for postoperative high-risk locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) is chemoradiotherapy with 3-weekly cisplatin (100 mg/m2). However, whether chemoradiotherapy with weekly cisplatin (40 mg/m2) yields comparable efficacy with 3-weekly cisplatin in postoperative high-risk LA-SCCHN is unknown. PATIENTS AND METHODS: In this multi-institutional open-label phase II/III trial, patients with postoperative high-risk LA-SCCHN were randomly assigned to receive either chemoradiotherapy with 3-weekly cisplatin (100 mg/m2) or with weekly cisplatin (40 mg/m2) to confirm the noninferiority of weekly cisplatin. The primary end point of phase II was the proportion of treatment completion, and that of phase III was overall survival. A noninferiority margin of hazard ratio was set at 1.32. RESULTS: Between October 2012 and December 2018, a total of 261 patients were enrolled (3-weekly cisplatin, 132 patients; weekly cisplatin, 129 patients). At the planned third interim analysis in the phase III part, after a median follow-up of 2.2 (interquartile range 1.19-3.56) years, chemoradiotherapy with weekly cisplatin was noninferior to 3-weekly cisplatin in terms of overall survival, with a hazard ratio of 0.69 (99.1% CI, 0.374 to 1.273 [< 1.32], one-sided P for noninferiority = .0027 < .0043). Grade 3 or more neutropenia and infection were less frequent in the weekly arm (3-weekly v weekly, 49% v 35% and 12% v 7%, respectively), as were renal impairment and hearing impairment. No treatment-related death was reported in the 3-weekly arm, and two (1.6%) in the weekly arm. CONCLUSION: Chemoradiotherapy with weekly cisplatin is noninferior to 3-weekly cisplatin for patients with postoperative high-risk LA-SCCHN. These findings suggest that chemoradiotherapy with weekly cisplatin can be a possible treatment option for these patients.

  英語, 研究論文（学術雑誌）, OBJECTIVE: This study aimed to quantify the cell-free deoxyribonucleic acid (DNA), citrullinated-histone H3 (cit-H3)-DNA complex, and myeloperoxidase (MPO)-DNA complex as extracellular trap cell death (ETosis)-derived products in the middle ear fluid, and to identify diagnostic biomarkers for the discrimination of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV) from eosinophilic otitis media (EOM). STUDY DESIGN: Prospective study. SETTING: Tertiary referral center. PATIENTS: OMAAV patients were eligible for inclusion in this analysis. Patients with EOM were examined as controls. INTERVENTION: All samples were obtained from the middle ear fluid in patients with OMAAV or EOM. The fluid samples were aspirated from the middle ear through the anterior-inferior portion of the tympanic membrane using a 1-ml tuberculin syringe with a 24- or 26-gauge needle under a microscope. MAIN OUTCOME MEASURES: The levels of cell-free DNA, cit-H3-DNA complex and MPO-DNA complex in the fluid samples were quantified using an enzyme-linked immunosorbent assay. RESULTS: Patients with OMAAV showed significantly higher levels of MPO-DNA complex compared to patients with EOM, regardless of the serum ANCA status at the time of sampling (p < 0.001 and p < 0.001, respectively). Meanwhile, there were no significant differences in the values of cell-free DNA or cit-H3-DNA complex between the OMAAV and EOM patients. CONCLUSION: The findings of this study suggest that the detection and quantification of MPO-DNA complex in the otitis media fluid can be utilized to discriminate OMAAV, especially in cases of eosinophilic granulomatosis with polyangiitis, from EOM regardless of the serum ANCA status. It should be noted that it is possible for cell-free DNA and cit-H3-DNA complex in fluid samples to be derived from dead cells other than neutrophils that undergo ETosis.

  英語, 研究論文（学術雑誌）, There are no established guidelines for managing older patients with head and neck cancer. Most clinical trials that define current standard therapy included few elderly patients. On the other hand, there is great variability in patients' comorbidities, physical functions, cognitive function, familial and financial background and values. The key point appears to be appropriate geriatric assessment, clarifying the patients' outcomes and a multidisciplinary team approach, including the treatment decision-making policy. Although these processes should be scientific in nature, the evidence for the treatment of elderly head and neck patients is very limited. This review summarizes the evidence available regarding the management of geriatric assessment, each treatment modality and the multidisciplinary team approach for older patients with head and neck cancers.

  英語, A 66-year-old man underwent multimodal treatment for olfactory neuroblastoma (ONB). When he was 72 years old, a cystic intracranial lesion without accumulation on fluorine-18-fluorodeoxyglucose positron emission tomography was detected. Surgical resection was performed when the patient was 73 years old. The pathological examination revealed recurrence of ONB, and the patient underwent focal irradiation. At age 81, he presented with a second recurrence in the right occipital lobe with radiological and pathological findings similar to the prior recurrence. This case suggests that pathological confirmation should be considered in cases with atypical radiological findings following the treatment of ONB.

  英語, 研究論文（学術雑誌）, Recently, Schlafen family member 11 (SLFN11) has been reported to increase the sensitivity of cancer cells to DNA-damaging agents, including platinum derivatives; thus, SLFN11 may be a predictive biomarker for platinum-based chemoradiotherapy (CRT). In this study, we examined whether SLFN11 expression was associated with the therapeutic outcome of platinum-based CRT in head and neck squamous cell carcinoma (HNSCC). We performed immunohistochemical analyses for SLFN11 expression in 161 HNSCC tissues from patients who had been administered cisplatin-based CRT and examined the correlation between SLFN11 expression and progression-free survival (PFS). Additionally, SLFN11 expression was examined in 10 paired samples obtained before and after CRT in patients with local failure. Furthermore, in vitro experiments were performed using several HNSCC cell lines and isogenic SLFN11-knockout cells to assess the association between SLFN11 expression and drug sensitivity. PFS was found to be significantly better in the SLFN11-positive group than in the SLFN11-negative group among the 161 patients (5-year PFS: 78.8% vs. 52.8%, respectively, p < 0.001). Similar results were observed for the PFS at each primary site. The percentage of SLFN11 positivity was lower in tumor samples from patients with local failure after CRT than that in the corresponding primary tumors before CRT in 8 of 10 cases. Results of the in vitro assay demonstrated that SLFN11-knockout cells exhibited reduced sensitivity to DNA-damaging agents but not to the non-DNA-damaging agent docetaxel. Our findings suggest that SLFN11 may serve as a potential biomarker for predicting the response of HNSCC patients to platinum-based CRT.

  英語, 研究論文（学術雑誌）, BACKGROUND: We have previously reported the effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) in real-world clinical practice in Japan. Here, we report long-term outcomes from this study in the overall population and subgroups stratified by subsequent chemotherapy. METHODS: In this multicenter, retrospective observational study, Japanese patients with recurrent or metastatic (R/M) HNC receiving nivolumab were followed up for 2 years. Effectiveness endpoints included overall survival (OS), OS rate, progression-free survival (PFS), and PFS rate. Safety endpoints included the incidence of immune-related adverse events (irAEs). RESULTS: Overall, 256 patients received a median of 6.0 doses (range: 1-52) of nivolumab over a median duration of 72.5 days (range: 1-736). Median OS was 9.5 months [95% confidence interval (CI) 8.2-12.0] and median PFS was 2.1 months (95% CI 1.8-2.7). A significant difference between 2-year survivors (n = 62) and non-2-year survivors was observed by median age (P = 0.0227) and ECOG PS (P = 0.0001). Of 95 patients who received subsequent chemotherapy, 54.7% received paclitaxel ± cetuximab. The median OS and PFS from the start of paclitaxel ± cetuximab were 6.9 months (95% CI 5.9-11.9) and 3.5 months (95% CI 2.3-5.5), respectively. IrAEs were reported in 17.2% of patients. Endocrine (7.0%) and lung (4.3%) disorders were the most common irAEs; kidney disorder (n = 1) was newly identified in this follow-up analysis. CONCLUSIONS: Results demonstrated the long-term effectiveness of nivolumab and potential effectiveness of subsequent chemotherapy in patients with R/M HNC in the real-world setting. Safety was consistent with that over the 1-year follow-up.

  英語, 研究論文（学術雑誌）, Purpose: Biologics have been used increasingly for the treatment of severe asthma. However, established guidelines for the selection, switching, or discontinuation of biologics do not exist. We aimed to identify the clinical characteristics of patients with asthma who required switching biologics and the factors associated with switching biologics. Patients and Methods: This was a retrospective study of 42 patients with severe asthma treated with biologics at the Hokkaido University Hospital between 23rd June 2016 and 30th April 2021, when two biologics were available in Japan. We compared the characteristics of subjects who continued and switched biologics. The time to switch the biologics was assessed by type 2 inflammatory biomarkers, pulmonary function indices, and the presence of comorbidities, including the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis (JESREC) score and aspirin exacerbated respiratory diseases (AERD), using the Kaplan-Meier method and a multivariate Cox proportional hazards model. Results: Eight and five patients were treated by mepolizumab and benralizumab at baseline, respectively among the 31% (13/42) who switched the biologics. Subjects who required switching biologics were characterized by high blood eosinophil counts, younger age, JESREC scores of 11 points or higher, and AERD. The time taken to switch biologics was significantly shorter in the subgroups with high JESREC scores (≥11) or AERD, compared with their counterparts with low JESREC scores or without AERD (both, P < 0.05). JESREC scores of ≥11, but not the presence of AERD, were associated with time to switch biologics. Conclusion: The presence of eosinophilic chronic rhinosinusitis based on JESREC scores of ≥11 and younger age were factors associated with switching biologics in asthma.

  英語, 研究論文（学術雑誌）, PURPOSE: Radiation dermatitis is one of the most common acute toxicities induced by chemoradiation therapy (CRT) for head and neck cancer (HNC). The benefit of topical steroids in the management of radiation dermatitis is still unclear. This phase 3, multi-institutional, randomized, double-blind, placebo-controlled trial evaluated the efficacy and safety of topical steroids for radiation dermatitis in patients with locally advanced HNC receiving CRT. METHODS AND MATERIALS: Eligible patients were scheduled to receive bilateral neck irradiation (≥66 Gy) with concurrent cisplatin (≥200 mg/m2) as definitive or postoperative CRT. Patients were randomly assigned to receive either topical steroid or placebo when grade 1radiation dermatitis was observed or the total radiation dose reached 30 Gy. Basic skin care including gentle washing and moistening in the head and neck region was performed in both groups. The primary endpoint was the frequency of grade ≥2 radiation dermatitis, in accordance with the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0. Grading of radiation dermatitis was performed by independent central review using photographs taken weekly. RESULTS: A total of 211 patients were enrolled (intention to treat: steroid 101 and placebo 102). The frequency of grade ≥2 radiation dermatitis was not significantly reduced with the steroid (73.3%; 95% confidence interval, 64.6%-81.9%) compared with the placebo (80.4%; 95% confidence interval, 72.7%-88.1%; P = .23), whereas the steroid significantly reduced the frequency of grade ≥3 radiation dermatitis (13.9% vs 25.5%; P = .034). No significant differences in adverse events, including local infection or compliance with CRT, were observed between the groups. CONCLUSIONS: Topical steroid may reduce the severity of radiation dermatitis in patients with HNC and thus may become an important therapeutic tool in the management of radiation dermatitis.

  研究論文（学術雑誌）, Objective: Traditionally, cadaveric courses have been an important tool in surgical education for Functional Endoscopic Sinus Surgery (FESS). The recent COVID-19 pandemic, however, has had a significant global impact on such courses due to its travel restrictions, social distancing regulations, and infection risk. Here, we report the world-first remote (Functional Endoscopic Sinus Surgery) FESS training course between Japan and Australia, utilizing novel 3D-printed sinus models. We examined the feasibility and educational effect of the course conducted entirely remotely with encrypted telemedicine software.
  
  Methods: Three otolaryngologists in Hokkaido, Japan, were trained to perform frontal sinus dissections on novel 3D sinus models of increasing difficulty, by two rhinologists located in Adelaide, South Australia. The advanced manufactured sinus models were 3D printed from the Computed tomography (CT) scans of patients with chronic rhinosinusitis. Using Zoom and the Quintree telemedicine platform, the surgeons in Adelaide first lectured the Japanese surgeons on the Building Block Concept for a three Dimensional understanding of the frontal recess. They in real time directly supervised the surgeons as they planned and then performed the frontal sinus dissections. The Japanese surgeons were asked to complete a questionnaire pertaining to their experience and the time taken to perform the frontal dissection was recorded. The course was streamed to over 200 otolaryngologists worldwide.
  
  Results: All dissectors completed five frontal sinusotomies. The time to identify the frontal sinus drainage pathway (FSDP) significantly reduced from 1,292 ± 672 to 321 ± 267 s (p = 0.02), despite an increase in the difficulty of the frontal recess anatomy. Image analysis revealed the volume of FSDP was improved (2.36 ± 0.00 to 9.70 ± 1.49 ml, p = 0.014). Questionnaires showed the course's general benefit was 95.47 ± 5.13 in dissectors and 89.24 ± 15.75 in audiences.
  
  Conclusion: The combination of telemedicine software, web-conferencing technology, standardized 3D sinus models, and expert supervision, provides excellent training outcomes for surgeons in circumstances when classical surgical workshops cannot be realized.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Recently, depleted tissue zinc levels were found in nasal mucosa from patients with chronic rhinosinusitis (CRS) in correlation with tissue eosinophilia, however, no clinical biomarkers for tissue zinc levels have been identified. Metallothionein-3 (MT3) is an intracellular zinc chelator and previous data showed MT3 mRNA levels to be reduced in CRS patients with nasal polyps (CRSwNP). In this study, we examined the correlation between MT3 expression and zinc levels in nasal mucosa and primary human nasal epithelial cells (HNECs) to investigate whether MT3 could be a clinical biomarker for tissue zinc levels. METHOD: Tissue was harvested from 36 patients and mounted on tissue micro-array (TMA) slides. MT3 expression and tissue zinc fluorescence intensity were measured at different areas within the mucosa (surface epithelium and lamina propria) and compared between controls, CRSwNP and CRS without nasal polyps (CRSsNP) patients. MT3 mRNA and protein expression were examined in zinc-depleted HNECs by qPCR and immunofluorescence microscopy. RESULTS: MT3 expression in CRSwNP was significantly decreased in both surface epithelium (p<0.001 to controls) and lamina propria (p = 0.0491 to controls). There was a significant positive correlation between tissue zinc levels and MT3 expression in nasal mucosa (r = 0.45, p = 0.007). In zinc-deplete HNECs, MT3 expression was significantly decreased at mRNA (p = 0.02) and protein level (p<0.01). There was a significant positive correlation between tissue zinc levels and MT3 expression within individual HNECs (r = 0.59, p<0.001). CONCLUSIONS: MT3 expression reflects intramucosal zinc levels in both nasal mucosa and HNECs indicating MT3 could be used as a clinical biomarker for monitoring intracellular zinc levels in the nasal mucosa.

  英語, 研究論文（学術雑誌）, HYPOTHESIS: We hypothesized that an anomalous change of Notch signaling might be involved in the pathophysiology of cholesteatoma. BACKGROUND: The Notch signaling pathway regulates integrated growth and differentiation control of keratinocytes. Its involvement in cholesteatoma proliferation has not been elucidated. METHODS: We obtained cholesteatoma and external auditory canal (EAC) skin samples from patients with middle ear cholesteatoma who underwent tympanomastoid surgery. We performed polymerase chain reaction using the RT2 Profiler™ PCR Array Human Notch Signaling Pathway (Qiagen) in the cholesteatoma and EAC skin samples (n = 6 each). This was followed by immunohistochemical staining of Notch1, enhancer of split-1 (HES1), and p53 in 41 and 8 cholesteatoma and EAC skin samples, respectively. RESULTS: The fold change of Notch1 gene expression was lowest in cholesteatoma, with a statistically significant difference (p = 0.0424). Moreover, the fold change of HES1 expression decreased (p = 0.272). The positive rates of Notch1 and HES1 protein expressions in the cholesteatoma (48.5 ± 32.4% and 44.9 ± 17.8%, respectively) were significantly lower than in the EAC skin (83.4 ± 17.5% and 55.7 ± 7.1%, respectively) (p < 0.001 and p < 0.01). In contrast, the positive rate of p53 expression in the cholesteatoma (8.5 ± 11.4%) was significantly higher than in the EAC skin (0.5 ± 0.7%) (p < 0.001). CONCLUSION: The decreases in Notch1 and HES1 protein expression might play an important role in the hyperproliferative character of the keratinizing squamous epithelium in cholesteatoma. An increase in p53 might reflect the reaction to cellular hyperproliferation.

  英語, 研究論文（学術雑誌）, BACKGROUND: This study aimed to reveal the influence of the invasion site of external auditory canal (EAC) cancer by analyzing the outcome of patients with advanced tumor. METHODS: A total of 111 patients with T4 EAC cancer were enrolled in this study. Of these patients, 79 underwent chemoradiotherapy and 32 underwent surgery under curative intent. Univariate and multivariate analyses and the Kaplan-Meier method were used to focus on the tumor invasion sites and overall survival of the patients. RESULTS: The 3-year overall survival rate of all patients was 55.0%. In multivariate analysis, the only significant invasion site for overall survival was the facial nerve, with the dura mater being the next most influential site. When Kaplan-Meier survival curve was calculated, facial nerve and dura mater were the significant factors resulting in poor patient outcomes. CONCLUSION: The facial nerve and dura mater are crucial sites of EAC cancer for patient outcomes.

  英語, 研究論文（学術雑誌）, BACKGROUND: This study aimed to assess the utility of deep learning analysis using pretreatment FDG-PET images to predict local treatment outcome in oropharyngeal squamous cell carcinoma (OPSCC) patients. METHODS: One hundred fifty-four OPSCC patients who received pretreatment FDG-PET were included and divided into training (n = 102) and test (n = 52) sets. The diagnosis of local failure and local progression-free survival (PFS) rates were obtained from patient medical records. In deep learning analyses, axial and coronal images were assessed by three different architectures (AlexNet, GoogLeNET, and ResNet). In the training set, FDG-PET images were analyzed after the data augmentation process for the diagnostic model creation. A multivariate clinical model was also created using a binomial logistic regression model from a patient's clinical characteristics. The test data set was subsequently analyzed for confirmation of diagnostic accuracy. Assessment of local PFS rates was also performed. RESULTS: Training sessions were successfully performed with an accuracy of 74-89%. ROC curve analyses revealed an AUC of 0.61-0.85 by the deep learning model in the test set, whereas it was 0.62 by T-stage, 0.59 by clinical stage, and 0.74 by a multivariate clinical model. The highest AUC (0.85) was obtained with deep learning analysis of ResNet architecture. Cox proportional hazards regression analysis revealed deep learning-based classification by a multivariate clinical model (P < .05), and ResNet (P < .001) was a significant predictor of the treatment outcome. In the Kaplan-Meier analysis, the deep learning-based classification divided the patient's local PFS rate better than the T-stage, clinical stage, and a multivariate clinical model. CONCLUSIONS: Deep learning-based diagnostic model with FDG-PET images indicated its possibility to predict local treatment outcomes in OPSCCs.

  英語, 研究論文（学術雑誌）, OBJECTIVES: The aim of the present study was to investigate the characteristics and prognosis of facial palsy in patients with otitis media with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (OMAAV). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Thirty-seven patients with OMAAV. MAIN OUTCOME MEASURES: The patients were divided into the facial palsy group and non-palsy group. The severity of and prognosis for facial palsy were evaluated using the House-Brackmann facial grading system (HB). Characteristics were compared between the facial palsy group and non-palsy group. RESULTS: Facial palsy was observed in eight patients. The last HB grade for all patients was either grade I or II after treatment with a combination of corticosteroids and immunosuppressant therapy. There were no cases in which palsy relapsed. Facial palsy in OMAAV was significantly more common in female patients, and patients with facial palsy demonstrated significantly higher rates of hypertrophic pachymeningitis than did those without facial palsy. CONCLUSIONS: Facial palsy in patients with OMAAV was detected in 21.6% and a good prognosis was obtained by use of the appropriate treatment. Facial palsy is one of the most important symptoms by which to diagnose OMAAV. When encountering the patients with intractable otitis media complicated with facial palsy, appropriate examination including ANCA titer should be performed.

  英語, 研究論文（学術雑誌）, BACKGROUND: We investigated whether prophylactic percutaneous endoscopic gastrostomy (PEG) is used effectively for patients treated with definitive concurrent chemoradiotherapy (CCRT) and the predictors of the need for PEG. METHODS: 326 patients with laryngeal, oropharyngeal or hypopharyngeal cancers were retrospectively reviewed. RESULTS: The PEG tube use group had more favorable results than the total parenteral nutrition and nasogastric tube groups in terms of rate of serum albumin loss, incidence of severe fever and aspiration pneumonia, CCRT completion rate and hospitalization period. However, it was inferior to oral intake. Analysis of the relative risk of requiring enteral or parenteral nutrition revealed that performance status (PS) 2, primary site (supraglottis, oropharynx, or hypopharynx), N3 disease, and cisplatin were predictors of the need for nutritional support. CONCLUSIONS: Prophylactic PEG is effective for patients treated with definitive CCRT and is especially required for patients with PS2 or oropharyngeal cancer.

  英語, 研究論文（学術雑誌）, PURPOSE: This study aimed to compare patients with early oral cavity squamous cell carcinoma (OCSCC) (tumor category [T] 1-2, node-negative, and no distant metastasis) treated with traditional elective neck dissection (ND) with those managed by sentinel lymph node biopsy (SLNB) using survival and neck function and complications as end points. METHODS: Sixteen institutions in Japan participated in the study (trial registration number: UMIN000006510). Patients of age ≥ 18 years with histologically confirmed, previously untreated OCSCC (Union for International Cancer Control TNM Classification of Malignant Tumors 7th edition T1-2, node-negative no distant metastasis), with ≥ 4 mm (T1) depth of invasion, were randomly assigned to undergo standard selective ND (ND group; n = 137) or SLNB-navigated ND (SLNB group; n = 134). The primary end point was the 3-year overall survival rate, with a 12% noninferiority margin; secondary end points included postoperative neck functionality and complications and 3-year disease-free survival. Sentinel lymph nodes underwent intraoperative multislice frozen section analyses for the diagnosis. Patients with positive sentinel lymph nodes underwent either one-stage or second-look ND. RESULTS: Pathologic metastasis-positive nodes were observed in 24.8% (34 of 137) and 33.6% (46 of 134) of patients in the ND and SLNB groups, respectively (P = .190). The 3-year overall survival in the SLNB group (87.9%; lower limit of one-sided 95% CI, 82.4) was noninferior to that in the ND group (86.6%; lower limit 95% CI, 80.9; P for noninferiority < .001). The 3-year disease-free survival rate was 78.7% (lower limit 95% CI, 72.1) and 81.3% (75.0) in the SLNB and ND groups, respectively (P for noninferiority < .001). The scores of neck functionality in the SLNB group were significantly better than those in the ND group. CONCLUSION: SLNB-navigated ND may replace elective ND without a survival disadvantage and reduce postoperative neck disability in patients with early-stage OCSCC.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Involvement in the tracheostomy procedure for COVID-19 patients can lead to a feeling of fear in medical staff. To address concerns over infection, we gathered and analyzed experiences with tracheostomy in the COVID-19 patient population from all over Japan. METHODS: The data for health-care workers involved in tracheostomies for COVID-19-infected patients were gathered from academic medical centers or their affiliated hospitals from all over Japan. RESULTS: Tracheostomies have been performed in 35 COVID-19 patients with a total of 91 surgeons, 49 anesthesiologists, and 49 surgical staff members involved. Twenty-eight (80%) patients underwent surgery more than 22 days after the development of COVID-19-related symptoms (11: 22-28 days and 17: ≥29 days). Thirty (85.7%) patients underwent surgery ≥ 15 days after intubation (14: 15-21 days, 6: 22-28 days, and 10: ≥29 days). Among the total of 189 health-care workers involved in the tracheostomy procedures, 25 used a powered air-purifying respirator (PAPR) and 164 used a N95 mask and eye protection. As a result, no transmission to staff occurred during the 2 weeks of follow-up after surgery. CONCLUSION: No one involved in tracheostomy procedures were found to have been infected with COVID-19 in this Japanese study. The reason is thought to be that the timing of the surgery was quite late after the infections, and the surgery was performed using appropriate PPE and surgical procedure.

  英語, 研究論文（学術雑誌）, BACKGROUND: To examine the effect of prior use of cetuximab and neck dissection on the effectiveness of nivolumab, we conducted a large-scale subgroup analysis in Japanese patients with recurrent/metastatic head and neck cancer. METHODS: Data on the effectiveness of nivolumab were extracted from patient medical records. All patients were analyzed for effectiveness by prior cetuximab use. In the analyses for prior neck dissection, only patients with locally advanced disease were included. RESULTS: Of 256 patients analyzed, 155 had received prior cetuximab. Nineteen of 50 patients with local recurrence underwent neck dissection. The objective response rate was 14.7 vs 17.2% (p = 0.6116), median progression-free survival was 2.0 vs 3.1 months (p = 0.0261), and median overall survival was 8.4 vs 12 months (p = 0.0548) with vs without prior cetuximab use, respectively. The objective response rate was 23.1 vs 25.9% (p = 0.8455), median progression-free survival was 1.8 vs 3.0 months (p = 0.6650), and median overall survival was 9.1 vs 9.9 months (p = 0.5289) with vs without neck dissection, respectively. CONCLUSIONS: These findings support the use of nivolumab for patients with recurrent/metastatic head and neck cancer regardless of prior cetuximab use or neck dissection history.

  英語, 研究論文（学術雑誌）, The inherent variability in performing specific surgical procedures for head and neck cancer remains a barrier for accurately assessing treatment outcomes, particularly in clinical trials. While non-surgical modalities for cancer therapeutics have evolved to become far more uniform, there remains the challenge to standardize surgery. The purpose of this review is to identify the barriers in achieving uniformity and to highlight efforts by surgical groups to standardize selected operations and nomenclature. While further improvements in standardization will remain a challenge, we must encourage surgical groups to focus on strategies that provide such a level.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Several methods have been reported to correct caudal deviation of the nasal septum, including open septorhinoplasty (OSR) and septoplasty with Killian incision (KI). In general, OSR is applied instead of KI for caudal deviation. However, there is little objective evidence own on the effects of OSR and KI for caudal deviation. In this study, we compared surgical outcomes between OSR and KI by quantifying nasal septum deviation using two simple and objective parameters on routine paranasal sinus CT scans. METHODS: We retrospectively analyzed 18 patients who underwent OSR and 11 patients who underwent septoplasty with KI between April 2006 and October 2019. Caudal deviation was defined on the basis of the "Anterior-posterior Position of the most deviated point of the nasal septum (AP)," which was measured on computerized tomography. The deformation rate (DR) of the nasal septum was also calculated. Nasal airway resistance and visual analogue scale (VAS) score for nasal obstruction were examined. RESULTS: The AP was significantly correlated with the VAS score (r=-0.58, p=0.017). The DR in patients with caudal septal deviation was significantly decreased by OSR (0.14±0.06 to 0.03±0.03, p=0.004), but not by KI (0.09±0.08 to 0.04±0.03, p=0.25). OSR also improved nasal airway resistance (1.10±0.44 to 0.42±0.15, p=0.02), and the VAS score (79.11±14.74 to 5.78±7.89, p=0.004). CONCLUSION: Nasal obstruction is more severe in patients with the caudal deviation. OSR corrects caudal deviation of the nasal septum more effectively than does KI. The AP could be useful for the evaluation of the deviation of the nasal septum and help in selecting the appropriate septoplastic technique.

  英語, 研究論文（学術雑誌）, OBJECTIVE: The aim of the present study was to evaluate the psychological condition of patients with non-cured facial nerve palsy and to investigate whether their psychological condition is correlated with the degree of facial nerve palsy, synkinesis or quality of life. METHODS: Thirty patients with non-cured facial nerve palsy were enrolled in this study. Psychological conditions were evaluated by questionnaires including State-Trait Anxiety Inventory and Self-rating Depression Scale. RESULTS: Of the thirty patients with non-cured facial nerve palsy, 17 (56.7%) and 15 patients (50.0%) felt anxiety and depression, respectively. Although there were no significant correlations between their psychological condition and the degree of facial nerve palsy or that of sequelae, significant correlations were observed between psychological condition and the degree of QOL, especially in terms of social function. CONCLUSIONS AND SIGNIFICANCE: Disabilities associated with facial nerve palsy may be overlooked when evaluation is performed by physician-graded instruments alone. To resolve this problem, patients with non-cured facial nerve palsy should be evaluated by not only physician-graded tools but also patient-based assessment tools.

  英語, 研究論文（学術雑誌）, PURPOSE: We have performed superselective intra-arterial cisplatin infusion with concomitant radiotherapy (RADPLAT) for patients with maxillary sinus cancer. The promising treatment outcomes of this non-surgical treatment were reported in past studies. However, few clinical studies have been conducted to evaluate the outcome of salvage surgery following RADPLAT. The purpose of this study was to analyze the treatment outcomes of salvage surgery for patients with recurrent maxillary sinus cancer after RADPLAT. METHODS: We assessed 45 patients who had recurrence following RADPLAT between 1999 and 2017, and conducted a retrospective analysis. We excluded patients who did not complete RADPLAT. Patients were not considered to have completed RADPLAT if they underwent intra-arterial cisplatin less than three times or received a total radiation dose of less than 60 Gy. The primary endpoint was overall survival. The median follow-up period for surviving patients after recurrence was 5.1 years. RESULTS: Twenty-five of the 45 (56%) patients underwent salvage surgery. The 5-year overall survival rate was 68% in patients who underwent salvage surgery, while all patients who did not undergo salvage surgery died during the observation period. Fifteen of 24 (63%) patients with local recurrence underwent salvage surgery. Eight patients did not undergo salvage surgery because of unresectable disease; five of the eight patients had unresectable posterior extension. All nine patients with nodal recurrence underwent neck dissection. CONCLUSION: Treatment outcomes of salvage surgery following RADPLAT were favorable enough for it to be generally recommended. To reduce unresectable recurrence, the posterior section should be eradicated by RADPLAT.

  英語, 研究論文（学術雑誌）, OBJECTIVES: To investigate usefulness of the video Head Impulse Test (vHIT) as a method for evaluating semicircular canal function in patients with otitis media with antineutrophil cytoplasmic antibody-associated vasculitis (OMAAV). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Fourteen patients with OMAAV underwent vestibular examination. MAIN OUTCOME MEASURES: The gain in vestibulo-ocular reflex (VOR) and the presence of catch-up saccade were examined for each semicircular canal. RESULTS: Seven (50.0%) of the 14 patients felt subjective symptoms of disequilibrium. Dysfunction in at least one semicircular canal was detected in all ears of the OMAAV patients evaluated by vHIT. Dysfunction in posterior semicircular canal was detected more frequently than that in the anterior or horizontal canal. There were no significant correlations between the gain in VOR and hearing loss. CONCLUSIONS: vHIT is thought to be the most suitable method for evaluating semicircular canal function in patients with OMAAV as vHIT is not influenced by middle ear pathology and was able to evaluate vertical canal function including the posterior canal.

  英語, 研究論文（学術雑誌）, Zinc is an essential micronutrient in human body and a vital cofactor for the function of numerous proteins encoded by the human genome. Zinc has a critical role in maintaining many biochemical and physiological processes at the molecular, cellular, and multiple organ and systemic levels. The alteration of zinc homeostasis causes dysfunction of many organs and systems. In the immune system, zinc regulates the differentiation, proliferation and function of inflammatory cells, including T cells, eosinophils, and B cells, by modifying several signaling pathways such as NFκB signaling pathways and TCR signals. An adequate zinc level is essential for proper immune responses and decreased zinc levels were reported in many allergic inflammatory diseases, including atopic dermatitis, bronchial asthma, and chronic rhinosinusitis. Decreased zinc levels often enhance inflammatory activation. On the other hand, the inflammatory conditions alter the intracellular homeostasis of zinc, often decreasing zinc levels. These findings implied that there could be a vicious cycle between zinc deficiency and inflammatory conditions. In this review, we present recent evidence on the involvement of zinc in atopic dermatitis, bronchial asthma, and chronic rhinosinusitis, with insights into the involvement of zinc in the underlying molecular and cellular mechanisms related to these allergic inflammatory diseases.

  英語, 研究論文（学術雑誌）, Pharyngeal cancer patients treated with intensity-modulated proton therapy (IMPT) using a model-based approach were retrospectively reviewed, and acute toxicities were analyzed. From June 2016 to March 2019, 15 pharyngeal (7 naso-, 5 oro- and 3 hypo-pharyngeal) cancer patients received IMPT with robust optimization. Simulation plans for IMPT and intensity-modulated X-ray therapy (IMXT) were generated before treatment. We also reviewed 127 pharyngeal cancer patients with IMXT in the same treatment period. In the simulation planning comparison, all of the normal-tissue complication probability values for dysphagia, dysgeusia, tube-feeding dependence and xerostomia were lower for IMPT than for IMXT in the 15 patients. After completing IMPT, 13 patients completed the evaluation, and 12 of these patients had a complete response. The proportions of patients who experienced grade 2 or worse acute toxicities in the IMPT and IMXT cohorts were 21.4 and 56.5% for dysphagia (P < 0.05), 46.7 and 76.3% for dysgeusia (P < 0.05), 73.3 and 62.8% for xerostomia (P = 0.43), 73.3 and 90.6% for mucositis (P = 0.08) and 66.7 and 76.4% for dermatitis (P = 0.42), respectively. Multivariate analysis revealed that IMPT was independently associated with a lower rate of grade 2 or worse dysphagia and dysgeusia. After propensity score matching, 12 pairs of IMPT and IMXT patients were selected. Dysphagia was also statistically lower in IMPT than in IMXT (P < 0.05). IMPT using a model-based approach may have clinical benefits for acute dysphagia.

  英語, 研究論文（学術雑誌）, BACKGROUND: To fill the data gap between clinical trials and real-world settings, this study assessed the overall effectiveness and safety of nivolumab in patients with head and neck cancer (HNC) during Japanese real-world clinical practice. METHODS: This was a multicenter, retrospective study in Japanese patients with recurrent or metastatic HNC who received nivolumab for the first time between July and December 2017. Data on the clinical use, effectiveness, and safety of nivolumab were extracted from patient medical records. RESULTS: Overall, 256 patients were enrolled in this study. The median duration of nivolumab treatment was 72.5 days, with patients receiving a median of 6.0 (range 1-27) doses. Median overall survival (OS) was 9.5 (95% confidence interval [CI] 8.2-12.0) months and the estimated 12-month OS rate was 43.2%. The objective response rate (ORR) was 15.7% overall and 21.1%, 7.1%, and 13.6% in patients with primary nasopharynx, maxillary sinus, and salivary gland tumors, respectively, who had been excluded from CheckMate 141. Grade ≥ 3 immune-related adverse events occurred in 5.9% of patients. No new safety signals were identified compared with adverse events noted in CheckMate 141. CONCLUSIONS: The effectiveness and safety of nivolumab in real-world clinical practice are consistent with data from the CheckMate 141 clinical trial. Therapeutic response was also observed in the groups of patients excluded from CheckMate 141. TRIAL REGISTRATION NUMBER: UMIN-CTR (UMIN000032600), Clinicaltrials.gov (NCT03569436).

  英語, 研究論文（学術雑誌）, OBJECTIVES: This study aimed to evaluate the efficacy of chemoradiotherapy (CRT) for patients with advanced cancer of the external auditory canal (EAC) by analyzing the outcome of the patients. METHODS: This is a multi-institutional retrospective survey, and we reviewed the medical records of the subjects. A total of 181 patients with tumor (T)3 or T4 tumor in 17 institutions were enrolled. Further analysis was performed for 74 patients who underwent CRT under curative intent. RESULTS: Overall 5-year survival rates of the patients who underwent CRT (n = 74) were 54.6%. Those of the patients who underwent CRT with modified TPF (docetaxel, cisplatin [CDDP], and 5-fluorouracil) regimen (n = 50) and CRT with CDDP regimens (n = 24) were 64.4% and 36.7%, respectively. Significant differences were observed between these two groups. CONCLUSION: Given the tendency that head and neck surgeons prefer CRT for advanced larger cancer of the EAC, CRT for advanced EAC cancer using the modified TPF regimen showed good clinical outcomes.

  英語, 研究論文（学術雑誌）, BACKGROUND: Vertigo or dizziness after stapes surgery occurs sometimes, and it is generally temporary. However, while rare, it can be prolonged. AIMS/OBJECTIVES: To investigate the prognostic factors for duration of vertigo following stapedotomy using a time-to-event analysis. MATERIALS AND METHODS: The present study included a total of 35 primary ears (26 with otosclerosis and nine with congenital stapes fixation) from 31 patients. We assessed residual rates of nystagmus and complaints of subjective vestibular symptoms using Kaplan-Meier time-to-event methods. RESULTS: Postoperative spontaneous nystagmus was observed in 23 (65.7%) ears, and postoperative subjective vestibular symptoms were confirmed in 27 (77.1%) ears. The total mean duration of postoperative spontaneous nystagmus and subjective vestibular symptoms was 9.8 (range: 0-158) and 33.9 days (0-732), respectively. A history of stapes surgery in the opposite ear was a significant predictive factor for prolonged nystagmus and subjective vestibular symptoms (p = .0059 and p = .0146). CONCLUSIONS AND SIGNIFICANCE: For individuals with a history of stapes surgery in the opposite ear, spontaneous nystagmus and vertigo/dizziness sensations following stapedotomy may persist for a longer duration than in those without a history of stapes surgery in the opposite ear.

  英語, 研究論文（学術雑誌）, In order to maximize the benefit of induction chemotherapy, practice based on a comprehensive interpretation of a large number of clinical trials, as in this review, is essential. The standard treatment for locally advanced squamous cell carcinoma of the head and neck is surgery or chemoradiation. However, induction chemotherapy followed by (chemo) radiotherapy may be used in some circumstances. Although many clinical trials of induction chemotherapy have been conducted, a rationale other than to preserve the larynx is still controversial. Selection of this modality should therefore be made with care. The current standard regimen for induction chemotherapy is docetaxel, cisplatin and 5-FU, but concerns remain about toxicity, cost and the duration of treatment. Regarding treatment after induction chemotherapy, it is also unclear whether radiation alone or chemoradiation is the better option. Furthermore, there is no answer as to what drugs should be used in combination with radiation therapy after induction chemotherapy. Several new induction chemotherapy treatment developments are currently underway, and future developments are expected. This review article summarizes the current position of induction chemotherapy for head and neck squamous cell carcinoma, based on the evidence produced to date, and discusses the future prospects for this treatment.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Despite of rapid advances in endoscopic surgery, the gold standard for sinonasal squamous cell carcinoma (SNSCC) surgery has remained the open approach with en-block resection due to the aggressive nature of SNSCC, including frequent recurrence and high mortality rate. For that reason, few studies have focused on SNSCC treated by endoscopic surgery alone. The objective of this study was to evaluate the usefulness of endoscopic surgery for patients with SNSCC. METHODS: A retrospective analysis was performed for 15 consecutive SNSCC patients who underwent endoscopic surgery without an open approach. We carefully selected patients whose tumor attachment sites could be fully visualized and completely resected through an endonasal approach. RESULTS: Of the fifteen patients, 4 patients (27%) were diagnosed with T1, 7 (47%) with T2, 4 (27%) with T3, and no patients with T4a or T4b disease. Four of the 15 (27%) patients showed positive surgical margins. The 5-yr overall survival, disease-specific survival, and local control rate was 72.4%, 79.6%, and 92.9%, respectively. The 5-yr disease-specific survival for T1, T2, and T3 disease was 100% and 75% and 75%, respectively. Patients with negative surgical margins had a better disease-specific survival rate than did those with positive surgical margins (p = 0.0253). CONCLUSION: Endoscopic surgery for patients with SNSCC appears to afford an effective method in selected cases. The achievement of negative surgical margins with a good view of the tumor attachment site was considered to be critical to the management of SNSCC.

  英語, 研究論文（学術雑誌）, BACKGROUND: The aims of this study are to evaluate the efficacy and safety of first-line treatment with chemotherapy plus cetuximab in real-world patients with recurrent or metastatic squamous cell carcinoma of the head and neck (RM-SCCHN) and to identify prognostic factors for overall survival (OS). METHODS: This is a prospective observation study involving 20 oncology institutions in Japan. Patients with RM-SCCHN treated with a first-line therapy consisting of cetuximab plus any chemotherapy regimen between December 2013 and February 2017 were enrolled. The primary objective of the study was 1-year OS. Secondary objectives included response rate and adverse events. RESULTS: Of 120 patients recruited, 114 patients were analyzed. Median age was 64 years. Cetuximab in combination with platinum plus 5-FU (EXTREME regimen) was chosen in 86 patients (75.4%). The median OS was 12.4 months. A point estimate of the 1-year survival rate was 51.1%. Overall response rate was 26.3%. Grade 3 or worse adverse events included neutropenia (22.8%), hypokalemia (9.6%), acneiform rash (7.0%), pneumonitis (1.8%), and infusion-related reaction (0.9%). On multivariate analysis, regional lymph node metastasis, absence of intervention by dermatologists, lack of response to therapy, skin metastasis, and non-EXTREME regimen were identified as independent unfavorable prognostic factors for OS. CONCLUSION: The combination of cetuximab plus chemotherapy was tolerable and efficacious in patients with RM-SCCHN in a real-world setting. Clinical outcomes and prognostic factors extracted from this study provide a reference of the current clinical practice as well as for the future development of novel therapy in RM-SCCHN.

  英語, 研究論文（学術雑誌）, Endonasal endoscopic surgery (EES) has been applied to the management of sinonasal (SN) tumors based on recent advances in endoscopic surgical techniques and technologies over the past three decades. EES has been mainly indicated for benign tumors and less aggressive malignant tumors. Notwithstanding this, EES has been gradually adopted for squamous cell carcinoma (SCC), which is the most common histology among SN malignancies. However, an analysis of the outcomes of EES for patients with SCC is difficult because most articles included SCC a wide range of different tumor histologies. Therefore, we herein review and clarify the current status of EES focusing on SCC from an oncological perspective. The oncologic outcomes and the ability to achieve a histologically complete resection are similar between endoscopic and open approaches in highly selected patients with SN-SCC. Surgical complications associated with EES are likely similar for SN-SCC compared to other sinonasal malignancies. The indications for a minimally invasive approach such as EES in the management of patients with SN-SCC should be stricter than those for less aggressive malignant tumors because of the aggressive nature of SCC. Also, it is important to achieve negative surgical margins with EES in patients with SCC. We believe that the indications for EES for SN-SCC are widening due to advances in diagnostic imaging, and endoscopic surgical techniques and technologies. However, while expanding the indications for EES for SN-SCC we must carefully confirm that the outcomes support this strategy.

  英語, 研究論文（学術雑誌）, The respiratory tract is constantly at risk of invasion by microorganisms such as bacteria, viruses, and fungi. In particular, the mucosal epithelium of the nasal cavity and paranasal sinuses is at the very forefront of the battles between the host and the invading pathogens. Recent studies have revealed that the epithelium not only constitutes a physical barrier but also takes an essential role in the activation of the immune system. One of the mechanisms equipped in the epithelium to fight against microorganisms is the Toll-like receptor (TLR) response. TLRs recognize common structural components of microorganisms and activate the innate immune system, resulting in the production of a plethora of cytokines and chemokines in the response against microbes. As the epithelia-derived cytokines are deeply involved in the pathogenesis of inflammatory conditions in the nasal cavity and paranasal sinuses, such as chronic rhinosinusitis (CRS) and allergic rhinitis (AR), the molecules involved in the TLR response may be utilized as therapeutic targets for these diseases. There are several differences in the TLR response between nasal and bronchial epithelial cells, and knowledge of the TLR signals in the upper airway is sparse compared to that in the lower airway. In this review, we provide recent evidence on TLR signaling in the upper airway, focusing on the expression, regulation, and responsiveness of TLRs in human nasal epithelial cells (HNECs). We also discuss how TLRs in the epithelium are involved in the pathogenesis of, and possible therapeutic targeting, for CRS and AR.

  英語, 研究論文（学術雑誌）, Purpose : To predict local control / failure by a multiparametric approach using magnetic resonance (MR)-derived tumor morphological and functional parameters in pharynx squamous cell carcinoma (SCC) patients. Materials and Methods : Twenty-eight patients with oropharyngeal and hypopharyngeal SCCs were included in this study. Quantitative morphological parameters and intratumoral characteristics on T2-weighted images, tumor blood flow from pseudo-continuous arterial spin labeling, and tumor diffusion parameters of three diffusion models from multi-b-value diffusion-weighted imaging as well as patients' characteristics were analyzed. The patients were divided into local control / failure groups. Univariate and multiparametric analysis were performed for the patient group division. Results : The value of morphological parameter of 'sphericity' and intratumoral characteristic of 'homogeneity' was revealed respectively significant for the prediction of the local control status in univariate analysis. Higher diagnostic performance was obtained with the sensitivity of 0.8, specificity of 0.75, positive predictive value of 0.89, negative predictive value of 0.6 and accuracy of 0.79 by multiparametric diagnostic model compared to results in the univariate analysis. Conclusion : A multiparametric analysis with MR-derived quantitative parameters may be useful to predict local control in pharynx SCC patients. J. Med. Invest. 68 : 354-361, August, 2021.

  英語, 研究論文（学術雑誌）, BACKGROUND: The standard of care for first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) in patients who cannot tolerate platinum-based regimens has not been clarified. We aimed to develop a new treatment regimen for patients with R/M SCCHN who are ineligible for platinum-based therapy, by evaluating the effects and safety of tegafur/gimeracil/oteracil (S-1) and cetuximab. METHODS: Platinum-ineligibility was defined as: elderly (aged ≥ 75 years), poor PS, comorbidity, platinum resistance and refusal to undergo platinum-based therapy. Patients received S-1 (80 mg/m2/day for 14 days followed by a seven-day break) and cetuximab (initial dose, 400 mg/m2, followed by 250 mg/m2 weekly) until disease progression or unacceptable toxicity. The primary endpoint was overall response rate (ORR). RESULTS: Between September 2014 and September 2018, we enrolled 23 patients. Among the 21 patients who were evaluable, 20 were male [median age, 69 years (range 49-82)]. The ORR was 9 (43%) of 21 patients [95% confidence interval (CI) 22-66]. One and eight patients achieved complete response (CR) and partial response (PR), respectively. The median overall survival (OS) was 13.7 months (95% CI 9.0-18.3) and progression-free survival (PFS) was 5.7 months (95% CI 3.1-8.2). Grade 3/4 adverse events included acneiform rash and skin reactions (33%), hypomagnesemia (19%), hand-foot syndrome (14%), fatigue (14%), mucositis (10%), and anorexia (10%). CONCLUSIONS: Combination treatment with S-1 and cetuximab was effective and tolerated well by patients with platinum-ineligible R/M SCCHN. Registered clinical trial number: UMIN000015123.

  英語, 研究論文（学術雑誌）, Background: From the first detection in 2019, SARS-CoV-2 infections have spread rapidly worldwide and have been proven to cause an urgent and important health problem. SARS-CoV-2 cell entry depends on two proteins present on the surface of host cells, angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine 2 (TMPRSS2). The nasal cavity is thought to be one of the initial sites of infection and a possible reservoir for dissemination within and between individuals. However, it is not known how the expression of these genes is regulated in the nasal mucosa. Objective: In this study, we examined whether the expression of ACE2 and TMPRSS2 is affected by innate immune signals in the nasal mucosa. We also investigated how fluticasone propionate (FP), a corticosteroid used as an intranasal steroid spray, affects the gene expression. Methods: Primary human nasal epithelial cells (HNECs) were collected from the nasal mucosa and incubated with Toll-like receptor (TLR) agonists and/or fluticasone propionate (FP), followed by quantitative PCR, immunofluorescence, and immunoblot analyses. Results: Among the TLR agonists, the TLR3 agonist Poly(I:C) significantly increased ACE2 and TMPRSS2 mRNA expression in HNECs (ACE2 36.212±11.600-fold change, p<0.0001; TMPRSS2 5.598±2.434-fold change, p=0.031). The ACE2 protein level was also increased with Poly(I:C) stimulation (2.884±0.505-fold change, p=0.003). The Poly(I:C)-induced ACE2 expression was suppressed by co-incubation with FP (0.405±0.312-fold change, p=0.044). Conclusion: The activation of innate immune signals via TLR3 promotes the expression of genes related to SARS-CoV2 cell entry in the nasal mucosa, although this expression is suppressed in the presence of FP. Further studies are required to evaluate whether FP suppresses SARS-CoV-2 viral cell entry.

  英語, 研究論文（学術雑誌）, OBJECTIVE: The aim of this supplemental study of a sentinel node (SN) biopsy (SNB) trial for oral squamous cell carcinoma (OSCC) was to assess the effectiveness in identifying micrometastasis and determining whether elective neck dissection (END) is necessary. MATERIALS AND METHODS: Twenty-three patients with pathologically positive SNs were included. The sizes of the metastatic lesions in positive SNs (SMSNs) were classified and the rates of occult metastasis of non-SNs were compared. RESULTS: The patients were divided according to the SMSN:<0.2 mm (group A, n=3);0.2 mm to <2.0 mm (group B, n=7);and ≥2.0 mm (group C, n=13). The rates of occult metastasis in groups A, B, and C were 0% (0/3), 14% (1/7) and 23% (3/13), respectively. CONCLUSION: Rare cancer cell distribution to nodes other than SNs was observed in the patients with SN metastatic lesions of at least smaller than 0.2 mm in size, suggesting the possibility of defining SN micrometastasis in N0 OSCC.

  英語, 研究論文（学術雑誌）, Purpose: A fluorescence-based technique for the detection of parathyroid glands (PGs) intraoperatively was previously reported. The technique was based on the phenomenon in which PGs emit autofluorescence when exposed to near-infrared light and we undertook an evaluation to consider the pathological accuracy of the method. Methods: The study comprised 17 patients (18 specimens) who underwent thyroid surgery at Kushiro City General Hospital between November 2018 and June 2019. We searched for PGs intraoperatively using a fluorescence spectroscopy system and evaluated the pathological accuracy of the system. We statistically evaluated the clinical factors associated with the accuracy of the system, including age, gender, body mass index, laterality, disease state, renal function, and comorbidity. Results: Eighteen specimens were evaluated pathologically, with 13 specimens confirmed as PGs. These were evaluated as “true positive,” giving a positive predictive value of 72.2% (13/18). Among the false-negative cases, one specimen was a metastatic lymph node in a patient with papillary thyroid carcinoma. There was a significant difference in the true-positive rates between malignant (25%) and benign (85.7%) disease (P = 0.044). Conclusion: We consider that this technique is useful, however, we have to exercise care in malignant cases as the true-positive rate may be low.

  英語, 研究論文（学術雑誌）, BACKGROUND: Zinc plays an important role in many biological processes. Reduced zinc levels have been found in chronic rhinosinusitis (CRS) patients, however, its role in the pathophysiology of this disease remains unknown. This study examined zinc levels in the serum, mucus and tissue from CRS patients in relation to collagen content and eosinophil infiltration. The effect of zinc depletion on inflammatory cytokine production and collagen synthesis was assessed in vitro. METHODOLOGY: Zinc levels were determined in serum, mucus and tissue from controls, CRS with (CRSwNP) and without nasal polyps (CRSsNP) patients. Tissue zinc levels, collagen and inflammatory cell infiltration was examined using zinquin assays, immunofluorescence and histology on Tissue Micro Arrays. Cytokine expression and collagen synthesis was evaluated in zinc depleted primary human nasal epithelial cells (HNECs) and primary fibroblasts. RESULTS: CRSwNP patients showed reduced tissue zinc levels in correlation with a reduction in collagen content, and increased eosinophil numbers. Zinc depletion of HNECs and fibroblasts induced the production of pro-inflammatory cytokines and MUC5AC and reduced collagen secretion. CONCLUSIONS: These results suggest mucosal zinc depletion associates with tissue eosinophilia and collagen depletion in CRSwNP and induces pro-inflammatory cytokine expression and reduction of collagen synthesis in vitro.

  英語, 研究論文（学術雑誌）, Squamous cell carcinoma of the head and neck is characterized by an immunosuppressive environment and evades immune responses through multiple resistance mechanisms. A breakthrough in cancer immunotherapy employing immune checkpoint inhibitors has evolved into a number of clinical trials with antibodies against programmed cell death 1 (PD-1), its ligand PD-L1 and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) for patients with squamous cell carcinoma of the head and neck. CheckMate141 and KEYNOTE-048 were practice-changing randomized phase 3 trials for patients with platinum-refractory and platinum-sensitive recurrent or metastatic squamous cell carcinoma of the head and neck, respectively. Furthermore, many combination therapies using anti-CTLA-4 inhibitors, tyrosine kinase inhibitors and immune accelerators are currently under investigation. Thus, the treatment strategy of recurrent or metastatic squamous cell carcinoma of the head and neck is becoming more heterogeneous and complicated in the new era of individualized medicine. Ongoing trials are investigating immunotherapeutic approaches in the curative setting for locoregionally advanced disease. This review article summarizes knowledge of the role of the immune system in the development and progression of squamous cell carcinoma of the head and neck, and provides a comprehensive overview on the development of immunotherapeutic approaches in both recurrent/metastatic and locoregionally advanced diseases.

  英語, 研究論文（学術雑誌）, Background: Although the close relationship between the upper and lower airways has been highlighted previously, little is known about the association between lung function and the recurrence of chronic rhinosinusitis with nasal polyps (CRSwNP). This study aimed to evaluate the factors associated with pulmonary function that affect CRSwNP recurrence after surgery.Methods: We performed a series of routine pulmonary function tests for general anesthesia prior to CRSwNP surgery. The values for each parameter were compared in the presence or absence of recurrence.Results: Sixty-nine patients with CRSwNP were included. The percent predicted forced expiratory volume in one second (%FEV1) in the recurrent group was significantly lower than that in the non-recurrent group (P = .005). A multivariable logistic regression model revealed that %FEV1 was a positive predictor of recurrence (odds ratio: 0.96, 95% CI: 0.92-0.99, P = .023). There were no significant differences in the other pulmonary functions between the two groups.Conclusions: We found that %FEV1 may be a predictor of CRSwNP recurrence after surgery. As %FEV1 is a pulmonary function test that is routinely performed before surgery, this parameter is readily applicable. Moreover, as %FEV1 appears to have the potential to reveal concealed asthma, %FEV1 might be a particularly useful tool for the prediction of CRSwNP recurrence after surgery.

  英語, 研究論文（学術雑誌）, The speed and scale of the global COVID-19 pandemic has resulted in unprecedented pressures on health services worldwide, requiring new methods of service delivery during the health crisis. In the setting of severe resource constraint and high risk of infection to patients and clinicians, there is an urgent need to identify consensus statements on head and neck surgical oncology practice. We completed a modified Delphi consensus process of three rounds with 40 international experts in head and neck cancer surgical, radiation, and medical oncology, representing 35 international professional societies and national clinical trial groups. Endorsed by 39 societies and professional bodies, these consensus practice recommendations aim to decrease inconsistency of practice, reduce uncertainty in care, and provide reassurance for clinicians worldwide for head and neck surgical oncology in the context of the COVID-19 pandemic and in the setting of acute severe resource constraint and high risk of infection to patients and staff.

  英語, 研究論文（学術雑誌）, OBJECTIVES: The aim of the present study was to evaluate semicircular canal function by video Head Impulse Test (vHIT) in patients with facial nerve schwannoma (FNS). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Seven patients with FNS underwent vHIT examination. MAIN OUTCOME MEASURES: The gain in vestibulo-ocular reflex and the presence of catch-up saccade were examined for the semicircular canals including the vertical canals. RESULTS: Dysfunction of the semicircular canals was detected by vHIT in three of seven cases. Nystagmus beating toward the non-affected side was observed in all three cases with semicircular canal dysfunction. Dysfunction was observed in a case with no direct compression of the vestibular nerve or semicircular canals by FNS. CONCLUSIONS: Semicircular canal function in patients with FNS could be evaluated by vHIT. vHIT has two advantages for the evaluation of vestibular function in patients with FNS. First, vHIT could be used for the patients in whom a tumor exists in the external auditory canal or middle ear, unlike caloric testing. Second, as vHIT could evaluate all three canals, impaired vestibular nerves could be speculated from vHIT results when a tumor exists in internal auditory canal. vHIT should be performed in patients with FNS, especially before surgery, to evaluate vestibular function.

  英語, 研究論文（学術雑誌）, Purpose: Recently it was reported that the parathyroid glands (PGs) emit autofluorescence when exposed to near infrared light, and a technique using fluorescence to detect the PGs intraoperatively was found to be useful. In some cases, however, it was difficult to detect the PGs. We sought to clarify the situation regarding such undetectable cases. Methods: The study comprised 45 patients (50 sides) who underwent thyroid or parathyroid surgery at Kushiro city general hospital between November 2018 and June 2019. We searched for the PGs intraoperatively using a fluorescence spectroscopy system. We statistically considered the factors related to the fluorescence patterns of background in cases in which two PGs could not be confirmed using Fisher’s exact test. Factors included age, gender, body-mass index, laterality, disease state, renal function, and comorbidity. Results: In 41 sides (82%) fluorescence from at least one PG was determined. There was no significant difference in the detection rates among the other clinical factors. A “White out” pattern in which the background was too bright to detect PGs was observed in 11 sides (22%), and a “Black out” pattern in which the background and PGs were dark was observed in 18 sides (36%). Malignant disease was statistically associated with a “White out” pattern. No factors were found to be related to the “Black out” pattern. Conclusion: In malignant disease, we should use this novel approach carefully.

  英語, 研究論文（学術雑誌）, BACKGROUND AND AIM: Immune checkpoint inhibitors (ICI) have revolutionized anti-malignancy therapy and thus have been increasingly used. Although ICI may cause immune-related adverse events (irAE) in various organs, including the liver, the prevalence and predictive factors of irAE have not been clarified. METHODS: In this retrospective study, consecutive patients who had malignancies and were treated with ICI without other chemotherapeutic agents at Hokkaido University Hospital between 2014 and 2019 were screened. Patients were excluded if they were < 20 years old and had insufficient clinical data. RESULTS: Of the 233 patients screened, 202 patients met the inclusion criteria and were included in the analysis. The patients were aged 25-92 years, and 60.9% were male. The patients received nivolumab (n = 137), pembrolizumab (n = 45), ipilimumab (n = 17), atezolizumab (n = 2), and avelumab (n = 1). The prevalence of any grade and grade ≥ 3 irAE hepatitis was 8.4% (17/202) and 4.0% (8/202), respectively. irAE hepatitis occurred at a median duration of 42 days in any grade and 36 days in grade ≥ 3 after ICI initiation. The clinical course of grade ≥ 3 irAE hepatitis was generally favorable; however, 50% required corticosteroid treatment and two patients required additional mycophenolate mofetil. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis. CONCLUSIONS: Grade ≥ 3 irAE hepatitis was observed in 4.0% of the patients who were treated with ICI. Female sex and history of ICI treatment were significantly associated with the incidence of grade ≥ 3 irAE hepatitis.

  英語, 研究論文（学術雑誌）, BACKGROUND: Induction chemotherapy (IC) in locally advanced squamous cell carcinoma of the head and neck (LA-SCCHN) often compromises compliance with subsequent chemoradiotherapy (CRT), which negatively affects outcomes. Here, we assessed the combination of paclitaxel (PTX), carboplatin (CBDCA), and cetuximab (Cmab) as IC for unresectable LA-SCCHN. METHODS: Induction chemotherapy consisted of weekly CBDCA area under the plasma concentration-time curve = 1.5, PTX 80 mg/m2 and Cmab with an initial dose of 400 mg/m2 followed by 250 mg/m2 for 8 weeks. Following IC, CDDP (20 mg/m2 , 4 days × 3 cycles) and concurrent radiotherapy (70 Gy/35 fr) were started. Primary endpoint was the proportion of CRT completion (%CRT completion). PCE was planned to be deemed effective if the Bayesian posterior probability (PP), defined as the probability that %CRT completion was larger than the threshold value of 65%, exceeded 84%. RESULTS: Thirty-five patients were enrolled. Cases were hypopharynx/oropharynx/larynx in 17/17/1 patients, all at Stage IV. Of 35 patients, 34 (97%) completed IC and 32 received CRT and met the criteria of full analysis set (FAS). In FAS, the %CRT completion was 96.9%, and PP was 99.9%, exceeding the prespecified boundary of 84%. Mean cumulative dose and relative to dose intensity of CDDP in CRT was 232.5 mg/m2 and 100%, respectively. Response rate was 88.6% by IC and 93.8% in the CRT phase. Three year overall survival was 83.5%. Main grade 3 toxicities included neutropenia (11.4%) and skin rash (5.7%) during IC; and oral mucositis (31.3%) and neutropenia (12.5%) during CRT. No grade 4 toxicity or treatment-related death was seen. CONCLUSIONS: PCE as IC was feasible, with promising efficacy and no effect on compliance with subsequent CRT in unresectable LA-SCCHN.

  英語, 研究論文（学術雑誌）, BACKGROUND: Sentinel node navigation surgery using indocyanine green (ICG-SNNS) can be performed in the operation room. The combination of minimally invasive transoral surgery (TOS) with ICG-SNNS can provide functional preservation options for both primary lesions and lymph node (LN) metastasis. This multicenter feasibility study of this strategy was conducted in Japan. METHODS: Patients with clinical T1 or T2, N0 oropharyngeal, hypopharyngeal, or supraglottic cancer were enrolled. The identification rate of sentinel nodes, delayed cervical LN metastasis in 2 years, and survival rate were assessed. RESULTS: Twenty-two patients (10 oropharynx, 8 hypopharynx, 4 supraglottic cancer) were enrolled. The identification rate was 100%. One case had delayed nodal metastasis. The accuracy was 95.5%, sensitivity was 75%, and specificity was 100%. The 5-year disease-specific survival was 100%, overall survival was 72.3%, and disease-free survival was 60.5%. CONCLUSIONS: The combination of TOS with ICG-SNNS is feasible as a minimally invasive strategy and has favorable oncological outcomes.

  Equilibrium Research, 79, 4, 251, 256, Japan Society for Equilibrium Research, 2020年
  日本語, 研究論文（学術雑誌）, Objective: To investigate the features of the Post Earthquake Dizziness Syndrome (PEDS) in Hokkaido by a questionnaire survey. Methods: A total of 50 patients with any kinds of vestibular disorders who experienced the huge earthquake in Hokkaido on September 6, 2018, were enrolled in this study. The characteristic symptoms in the patients with PEDS were investigated by a questionnaire survey. Result: Of the 50, 19 patients (38.0%) reported suffering from PEDS. The number of women with PEDS was significantly higher than the number of men (53.6% vs. 18.2%). There was no significant correlation between the age and the presence risk of PEDS. The typical symptom of PEDS was dizziness in the sitting position while indoors, the symptom disappearing within a minute. Conclusion: Patients with PEDS were detected after the earthquake in Hokkaido, similar to the case after other huge earthquakes in Japan. It is speculated that disturbances of the vestibular organs and psychological stress underlie the development of PEDS.

  英語, 研究論文（学術雑誌）, OBJECTIVE: The aim of the present study was to investigate the factors influencing semicircular canal function as evaluated by video Head Impulse Test (vHIT) in patients with vestibular schwannoma. METHODS: Twenty-four patients with untreated vestibular schwannoma underwent vHIT examination. The correlations between semicircular canal function and factors including age, tumor size, disease duration and hearing loss were evaluated. RESULTS: The functions of all three semicircular canals on the affected side evaluated by vHIT were significantly lower than those on the unaffected side. Although there were no significant correlations between semicircular canal function and age, tumor size or disease duration, a negative significant correlation between vestibulo-ocular reflex (VOR) gain as evaluated by vHIT and hearing loss was observed. CONCLUSIONS: From the results of the relationship between hearing loss and VOR gain, the damage to the audio and vestibular systems in patients with VS may be correlated. As it has been suggested that tumor size was not a significant factor in the VOR gain evaluated by vHIT, multifactorial causes rather than the simple compression of the vestibular nerves alone may be related to the dysfunction of the semicircular canals in patients with vestibular schwannoma.

  英語, 研究論文（学術雑誌）, Salivary duct carcinoma (SDC) is morphologically similar to breast cancer, with HER2-overexpression reported. With regard to the pattern of disease onset, SDC can arise from de novo or carcinoma ex-pleomorphic adenoma (Ca-ex-PA). Recently, multiple molecular profiles of SDC as well as breast cancer have been reported, with significant differences in HER2 expression between Ca-ex-PA and de novo. We assessed the differences in gene expression between onset classifications. We conducted immunohistochemical analysis and HER2-DISH for 23 patients and classified SDCs into three subtypes as follows: "HER2-positive" (HER2+/any AR), "Luminal-AR" (HER2-/AR+), and "Basal-like" (HER2-/AR-). We assessed the expression levels of 84 functional genes for 19 patients by using a qRT-PCR array. Ten cases were classified as HER2-positive, seven cases as Luminal-AR, and six cases as Basal-like. The gene expression pattern was generally consistent with the corresponding immunostaining classification. The expression levels of VEGFA, ERBB2(HER2), IGF1R, RB1, and XBP1 were higher, while those of SLIT2 and PTEN were lower in Ca-ex-PA than in de novo. The functions of those genes were concentrated in angiogenesis and AKT/PI3K signaling pathway (Fisher's test: p-value = 0.025 and 0.004, respectively). Multiple machine learning methods, OPLS-DA, LASSO, and RandomForest, also show that VEGFA can be a candidate for the characteristic differences between Ca-ex-PA and de novo. In conclusion, the AKT/PI3K signaling pathway leading to angiogenesis was hyper-activated in all SDCs, particularly in those classified into the Ca-ex-PAs. VEGFA was over-expressed significantly in the Ca-ex-PA, which can be a crucial factor in the malignant conversion to SDC.

  英語, 研究論文（学術雑誌）, Objectives: To explore the risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months in patients with unresectable locally advanced head and neck carcinomas who received chemoradiotherapy in a phase II trial of JCOG0706 (UMIN000001272).Methods: Forty-five patients received radiation therapy for a total of 70 Gy/35fr concurrently with S-1 and cisplatin. Risk factors of laryngo-esophageal dysfunction-free survival and nutritional support dependence over 12 months were analyzed using Cox regression models and logistic regression models, respectively, with consideration to patient laboratory data just before chemoradiotherapy. Radiation fields were reviewed to analyze the relationship between the extent of the irradiated field and functional outcome.Results: With a median follow-up period of 3.5 years, 3-year laryngo-esophageal dysfunction-free survival was 48.9%. For laryngo-esophageal dysfunction-free survival, hazards ratio of 2.35 in patients with nutritional support at registration (vs. without nutritional support; 95% confidence interval 0.96-5.76). For nutritional support dependence over 12 months, odds ratio was 6.77 in patients with hemoglobin less than the median of 13.4 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.24-36.85) and was 6.00 in patients with albumin less than the median of 3.9 g/dl (vs. higher than or equal to the median; 95% confidence interval 1.11-32.54). Primary sites in disease-free patients with nutritional support dependence over 12 months were the oropharynx (N = 2) or hypopharynx (N = 1), and all pharyngeal constrictor muscles were included in irradiated fields with a curative dose.Conclusions: This supplementary analysis showed that pretreatment severe dysphagia requiring nutritional support, anemia and hypoalbuminemia might have a negative prognostic impact on long-term functional outcomes after curative chemoradiotherapy in head and neck cancer.

  英語, 研究論文（学術雑誌）, OBJECTIVE: To perform comparisons and clarify differences in clinical manifestations between eosinophilic otitis media (EOM) and otitis media associated with eosinophilic granulomatosis with polyangiitis (EGPA). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: Twenty-two ears of 11 patients exhibiting EOM (EOM group) and 20 ears of 12 patients exhibiting otitis media associated with EGPA (EGPA group). MAIN OUTCOME MEASURES: Otological manifestations, nasal and paranasal manifestations, incidence of asthma, positivity for serum antineutrophil cytoplasmic antibodies (ANCA), total serum immunoglobulin (Ig) E level, peripheral blood eosinophil fraction, and hearing outcomes. RESULTS: The incidence and age of onset of asthma and chronic rhinosinusitis were comparable between the EOM and EGPA groups. Moreover, otological findings and hearing outcomes at the initial visit were similar in both groups. Computed tomography images of the paranasal sinus showed predominant opacification of the ethmoid sinus in both groups. Although the total serum IgE level was not significantly different, the peripheral blood eosinophil fraction was significantly larger in the EGPA group than in the EOM group (p = 0.0035). Furthermore, the rate of myeloperoxidase-antineutrophil cytoplasmic antibodies (ANCA) positivity was significantly higher in the EGPA group than in the EOM group (p = 0.019). CONCLUSIONS: The findings of the present study suggest that the phenotypic characteristics of EOM closely resemble those of otitis media associated with EGPA in early stages before the appearance of vasculitis. Therefore, it is challenging to differentiate the two conditions purely on the basis of otorhinological examinations.

  英語, 研究論文（学術雑誌）, OBJECTIVES: To investigate the effectiveness of make-up therapy for patients with facial nerve palsy. METHODS: Seven female patients with facial nerve palsy who received specialist make-up therapy were enrolled. The objective of the make-up therapy was to obtain a symmetrical facial appearance. RESULTS: Overall score for the Facial Clinimetric Evaluation (FaCE) scale was significantly improved after make-up therapy. There was a tendency for symptoms of depression to be improved among patients after make-up therapy. CONCLUSION: Make-up therapy to improve the symmetry of facial appearance could afford a noninvasive and low-cost treatment for patients with facial nerve palsy, especially in terms of patient quality of life and psychological condition.

  英語, 研究論文（学術雑誌）, Importance: Locoregionally advanced head and neck squamous cell cancer (HNSCC) is treated curatively; however, risk of recurrence remains high among some patients. The ERBB family blocker afatinib has shown efficacy in recurrent or metastatic HNSCC. Objective: To assess whether afatinib therapy after definitive chemoradiotherapy (CRT) improves disease-free survival (DFS) in patients with HNSCC. Design, Setting, and Participants: This multicenter, phase 3, double-blind randomized clinical trial (LUX-Head & Neck 2) studied 617 patients from November 2, 2011, to July 4, 2016. Patients who had complete response after CRT, comprising radiotherapy with cisplatin or carboplatin, with or without resection of residual disease, for locoregionally advanced high- or intermediate-risk HNSCC of the oral cavity, hypopharynx, larynx, or oropharynx were included in the study. Data analysis was of the intention-to-treat population. Interventions: Patients were randomized (2:1) to treatment with afatinib (40 mg/d) or placebo, stratified by nodal status (N0-2a or N2b-3) and Eastern Cooperative Oncology Group performance status (0 or 1). Treatment continued for 18 months or until disease recurrence, unacceptable adverse events, or patient withdrawal. Main Outcomes and Measures: The primary end point was DFS, defined as time from the date of randomization to the date of tumor recurrence or secondary primary tumor or death from any cause. Secondary end points were DFS at 2 years, overall survival (defined as time from the date of randomization to death), and health-related quality of life. Results: A total of 617 patients were studied (mean [SD] age, 58 [8.4] years; 528 male [85.6%]). Recruitment was stopped after a preplanned interim futility analysis on July 4, 2016, on recommendation from an independent data monitoring committee. Treatment was discontinued. Median DFS was 43.4 months (95% CI, 37.4 months to not estimable) in the afatinib group and not estimable (95% CI, 40.1 months to not estimable) in the placebo group (hazard ratio, 1.13; 95% CI, 0.81-1.57; stratified log-rank test P = .48). The most common grade 3 and 4 drug-related adverse effects were acneiform rash (61 [14.8%] of 411 patients in the afatinib group vs 1 [0.5%] of 206 patients in the placebo group), stomatitis (55 [13.4%] in the afatinib group vs 1 [0.5%] in the placebo group), and diarrhea (32 [7.8%] in the afatinib group vs 1 [0.5%] in the placebo group). Conclusions and Relevance: This study's findings indicate that treatment with afatinib after CRT did not improve DFS and was associated with more adverse events than placebo in patients with primary, unresected, clinically high- to intermediate-risk HNSCC. The use of adjuvant afatinib after CRT is not recommended. Trial Registration: ClinicalTrials.gov identifier: NCT01345669.

  英語, 研究論文（学術雑誌）, The purpose of this study was to determine the predictive power for treatment outcome of a machine-learning algorithm combining magnetic resonance imaging (MRI)-derived data in patients with sinonasal squamous cell carcinomas (SCCs). Thirty-six primary lesions in 36 patients were evaluated. Quantitative morphological parameters and intratumoral characteristics from T2-weighted images, tumor perfusion parameters from arterial spin labeling (ASL) and tumor diffusion parameters of five diffusion models from multi-b-value diffusion-weighted imaging (DWI) were obtained. Machine learning by a non-linear support vector machine (SVM) was used to construct the best diagnostic algorithm for the prediction of local control and failure. The diagnostic accuracy was evaluated using a 9-fold cross-validation scheme, dividing patients into training and validation sets. Classification criteria for the division of local control and failure in nine training sets could be constructed with a mean sensitivity of 0.98, specificity of 0.91, positive predictive value (PPV) of 0.94, negative predictive value (NPV) of 0.97, and accuracy of 0.96. The nine validation data sets showed a mean sensitivity of 1.0, specificity of 0.82, PPV of 0.86, NPV of 1.0, and accuracy of 0.92. In conclusion, a machine-learning algorithm using various MR imaging-derived data can be helpful for the prediction of treatment outcomes in patients with sinonasal SCCs.

  研究論文（学術雑誌）, © The Author(s) 2019. A number of major modifications were made to the classification of head and neck carcinomas in the eighth edition of the American Joint Committee on Cancer, Cancer Staging Manual and Union for International Cancer Control TNM classification of Malignant Tumors. These modifications were aimed at improving the prognosis prediction accuracy of the system. In this article, we review the new edition of the TNM classification system. Among the several changes in the new system, a separate algorithm for p16-positive oropharyngeal carcinoma was included, as were new chapters on ‘Head and Neck Skin Carcinoma’ and ‘Unknown Primary Carcinoma—Cervical Nodes.’ Changes to Tumor (T) classification were made by introducing the depth of invasion of oral carcinoma, whereas changes to Node (N) classification were made by adding extra-nodal extension. It is believed that these changes will help improve the accuracy of the system in the prediction of prognosis. However, it is necessary to verify their validity through further clinical research.

  英語, 研究論文（学術雑誌）, BACKGROUND: Locally advanced squamous cell carcinoma of the head and neck (LASCCHN) is usually treated with cisplatin (CDDP)-based chemoradiotherapy, except when patients are elderly or have renal, cardiac, or neurogenic dysfunction. This study compared the safety and efficacy of concurrent carboplatin (CBDCA) to cetuximab (Cmab) plus radiotherapy (RT) in patients ineligible for CDDP treatment. METHODS: We retrospectively analyzed LASCCHN patients who received CBDCA plus RT (n = 29) or Cmab plus RT (n = 18) due to ineligibility for CDDP treatment at two Japanese institutions between August 2006 and December 2015. RESULTS: Patients characteristics for CBDCA plus RT and Cmab plus RT were: median age, 74 and 75 years; 0-1 performance status, 90% and 100%; main primary tumor site, hypopharynx 52% (n = 15) and oropharynx 39% (n = 7); and stage IV, 90% (n = 26) and 50% (n = 9), respectively. With a median follow-up time of 60.0 months for CBDCA plus RT and 53.6 months for Cmab plus RT, 3-year locoregional control rates were 56% versus 58%, and median progression-free survival was 42.7 versus 11.6 months. CBDCA plus RT was associated with more grade 3/4 hematologic toxicities, including neutropenia and thrombocytopenia, whereas Cmab plus RT was associated with more grade 3/4 oral mucositis and radiation dermatitis. CONCLUSIONS: CBDCA or Cmab as a concurrent systemic therapy with RT is a possible treatment option for LASCCHN patients ineligible for CDDP treatment, although attention to hematological toxicity should be paid.

  英語, 研究論文（学術雑誌）, BACKGROUND: Desmoplastic small round cell tumor (DSRCT) is a rare soft tissue tumor that generally involves the retroperitoneum, pelvis, omentum and mesentery in younger patients. However, extra-abdominal DSRCT is very rare. CASE PRESENTATION: A 49-year-old Japanese man noticed a mass in the right parotid gland. Ultrasound examination revealed a solid tumor about 2 cm in diameter. Computed tomography (CT) of the whole body revealed no other tumors or lymph node swelling. Superficial parotidectomy was performed. Histologically, the tumor was composed of various-sized tumor cell nests in an abundant fibromyxoid and collagenous background. The tumor cells were small to medium-sized. Immunohistochemistry showed that the tumor cells were immunoreactive for epithelial markers and desmin. They also showed strong nuclear staining with a Wilms tumor 1 (WT1) antibody detecting the C-terminal region (C-WT1), but not the N-terminal region (N-WT1). We also performed 3'/5' expression imbalance assay based on reverse transcription polymerase chain reaction (RT-PCR) to determine whether aberrant WT1 gene expression was present. This tumor was found to lack 5'-regional expression of the WT1 gene, as well as immunoreactivity with the N-WT1 antibody. Finally, fluorescence in situ hybridization (FISH) and RT-PCR analyses revealed the presence of a gene showing fusion between exon 7 of EWSR1 and exon 8 of WT1. The tumor was diagnosed as a DSRCT of the right parotid gland. The patient has been followed for 3 years without recurrence or metastasis. CONCLUSIONS: Although DSRCT in the salivary gland is extremely rare, it should be included in the differential diagnosis of poorly differentiated salivary gland neoplasms, especially with a fibromyxoid background. Pathologists should bear in mind that DSRCT may occur in major salivary glands and should perform immunohistochemistry with appropriate antibodies, not only those against keratin and desmin, but also one detecting the C-terminal region of WT-1. Furthermore, molecular detection of EWSR1-WT1 fusion gene conclusively confirmed the diagnosis of DSRCT in this uncommon location.

  Japanese journal of clinical oncology, 49, 4, 297, 305, 2019年04月01日, ［査読有り］, ［国際誌］
  英語, The standard local treatment for early-stage tongue cancer with no clinical lymph node metastases is partial glossectomy. The frequency of occult lymph node metastasis is ~20-30%. Thus, whether prophylactic neck dissection with glossectomy or glossectomy alone should be performed has been a controversial issue since the 1980s. Both treatments have advantages and disadvantages; however, especially in cases involving prophylactic neck dissection, surgical invasion and complications including the cosmetic disadvantage caused by neck skin incision, accessory nerve paralysis or facial nerve (mandibular marginal branch) paralysis, stiffness of the shoulder or neck and a feeling of neck tightness have been considered issues that could be solved by providing less-invasive treatment to the 70-80% of patients without occult lymph node metastasis. A more accurate preoperative diagnosis and strict follow-up are required to provide minimally invasive treatment while ensuring the therapeutic effect. It is also necessary to narrow down the target based on the risk-benefit balance. The depth of invasion should be considered in cases involving oral cavity malignancies. This was also taken into account in recent revisions of eighth edition of the TNM Classification of Malignant Tumors and it is an important factor for N0 neck management. This review article summarizes previous and recent reports on neck management, focusing on the risk-benefit and future perspectives of the diagnosis and treatment of early-stage oral tongue cancer. This effort is an attempt to establish treatment from the patient's point of view, with the patient's quality of life taken into account.

  英語, 研究論文（学術雑誌）, OBJECTIVES: The aim of the present study was to investigate the prognostic factors for short-term hearing outcomes of ossiculoplasty for primary pars flaccida cholesteatoma according to the European Academy of Otology and Neurotology/Japanese Otological Society (EAONO/JOS) and 2015 JOS staging systems. MATERIALS AND METHODS: A total of 34 patients with primary pars flaccida cholesteatoma who underwent one-stage tympanomastoidectomy with partial ossicular reconstruction using double cartilage block were included in the study. The postoperative pure-tone average air-bone gap (PTA-ABG) was calculated, and two criteria of successful hearing outcomes were defined as ≤10 and ≤20 dB. Patients were classified according to the EAONO/JOS and 2015 JOS staging systems. Cochran-Armitage test was used to statistically analyze staging, and Fisher's exact test was used to analyze other factors. RESULTS: Successful hearing outcome with postoperative PTA-ABG ≤10 and ≤20 dB occurred in 23.5% and 55.9% of cases, respectively. When postoperative PTA-ABG ≤20 dB was defined as successful, the success rate significantly decreased with increase in EAONO/JOS stage, and S0 pathological status of the stapes (no involvement) was a significantly favorable predictive factor. When postoperative PTA-ABG ≤10 dB was regarded as successful, the significantly favorable predictive factors were S0 pathological status of the stapes and development of mastoid cells with MC2-3 (better developed cells). CONCLUSION: Favorable prognostic factors for hearing outcomes of tympanomastoidectomy with partial ossicular reconstruction for primary pars flaccida cholesteatoma were low stage following the EAONO/JOS staging system and no stapes involvement and better development of mastoid cells following the 2015 JOS staging system.

  日本語, 研究論文（学術雑誌）, BACKGROUND: Oral mucositis and body weight loss are the most critical conditions known to lead to the discontinuation of chemoradiotherapy for head and neck cancer. We investigated the effect of a nutritional supplement with a high blend ratio of w-3 fatty acids(Prosure®)on body weight loss, oral mucositis, and the completion rate of chemoradiotherapy in patients with oropharyngeal and hypopharyngeal cancer. PATIENTS AND METHODS: The study group comprised patients with oropharyngeal and hypopharyngeal cancer who were treated with concomitant cisplatin and 70 Gy of radiotherapy. These patients received 2 packs of Prosure®per day during chemoradiotherapy. RESULTS: A total of 17 patients were included in this study. The reduction in body weight was significantly improved compared with that in the historical control group that did not receive Prosure®(7.3% vs 10.3%, p<0.01), and the rate of Grade 3-4 oral mucositis was significantly reduced for the patient groups that received Prosure®(CTCAE v3.0 GradeB3; 24% vs 58%, p<0.05). The completion rate of chemoradiotherapy was not significantly different between both groups(77% vs 60%, NS). CONCLUSIONS: A nutritional supplement with a high blend ratio of w-3 fatty acids(Prosure®)had effects on oral mucositis and body weight loss in head and neck cancer patients treated with chemoradiotherapy.

  英語, 研究論文（学術雑誌）, OBJECTIVES:: The aim of this study was to investigate vertical semicircular canal function in patients with vestibular schwannoma (VS) by video head impulse test (vHIT). METHODS:: Fifteen patients with VS who had not received any treatment, including surgery or stereotactic radiotherapy, before vHIT examination were enrolled. Vestibulo-ocular reflex gain and catch-up saccade in vHIT were evaluated. RESULTS:: Dysfunction of anterior and posterior semicircular canals was detected by vHIT in 26.7% and 60.0%, respectively. Six patients (40.0%) demonstrated abnormalities referable to both vestibular nerve divisions. Abnormalities referable to the superior vestibular nerve were identified in 3 patients (20.0%), while 3 patients (20.0%) demonstrated a pattern indicative of inferior vestibular nerve involvement. Anterior semicircular canal vHIT produced fewer abnormalities than did either horizontal or posterior semicircular canal vHIT. CONCLUSIONS:: Dysfunction of the semicircular canals, including the vertical canals, in patients with VS was detected by vHIT. The anterior semicircular canal was less frequently involved than the horizontal or posterior semicircular canal. The examination of the vertical canals by vHIT is useful in the evaluation of vestibular function in patients with VS.

  英語, 研究論文（学術雑誌）, OBJECTIVE: This prospective study aimed to evaluate the diagnostic and clinical utility of the myeloperoxidase (MPO)-DNA complex as a NETosis-derived product in the middle ear fluid of patients with otitis media with antineutrophil cytoplasmic antibody-associated vasculitis (OMAAV). STUDY DESIGN: Prospective study. SETTING: Tertiary referral center. PATIENTS: Twenty-two patients diagnosed with OMAAV. INTERVENTION: Collection of the fluid samples from middle ear. MAIN OUTCOME MEASURE: The levels of the MPO-DNA complex in the fluid samples were quantified using an enzyme-linked immunosorbent assay. RESULTS: Patients with both systemic and localized forms of OMAAV showed significantly higher levels of the MPO-DNA complex compared to the controls (p < 0.001 and p = 0.002, respectively). In particular, they showed significantly higher levels of MPO-DNA complex compared to the controls, regardless of serum antineutrophil cytoplasmic antibody status (p < 0.001 and p < 0.001, respectively) or immunosuppressive therapy (p < 0.001 and p < 0.001, respectively) at the time of sampling. An optical density cutoff value of 0.16 at 405 nm according to the receiver operating characteristic curve showed a sensitivity of 86.4%, specificity of 95.5%, positive predictive value of 95.0% and negative predictive value of 87.5% for the diagnosis of OMAAV. Significant positive correlations were observed between the levels of MPO-DNA complex and the values for air conduction - (r = 0.49, p = 0.022) and bone conduction - pure tone average thresholds (r = 0.45, p = 0.035). CONCLUSIONS: The detection and quantification of the MPO-DNA complex in the otitis media fluid may aid in providing a definite diagnosis as well as predicting the activity and severity of OMAAV.

  英語, 研究論文（学術雑誌）, BACKGROUND: To assess the utility of histogram and texture analysis of magnetic resonance (MR) fat-suppressed T2-weighted imaging (Fs-T2WI) for the prediction of histological diagnosis of head and neck squamous cell carcinoma (SCC) and malignant lymphoma (ML). METHODS: The cases of 57 patients with SCC (45 well/moderately and 12 poorly differentiated SCC) and 10 patients with ML were retrospectively analyzed. Quantitative parameters with histogram features (relative mean signal, coefficient of variation, kurtosis and skewness) and gray-level co-occurrence matrix (GLCM) features (contrast, correlation, energy and homogeneity) were calculated using Fs-T2WI data with a manual tumor region of interest (ROI). RESULTS: The following significantly different values were obtained for the total SCC versus ML groups: relative mean signal (3.65 ± 0.86 vs. 2.61 ± 0.49), contrast (72.9 ± 16.2 vs. 49.3 ± 8.7) and homogeneity (2.22 ± 0.25 × 10- 1 vs. 2.53 ± 0.12 × 10- 1). In the comparison of the SCC histological grades, the relative mean signal and contrast were significantly lower in the poorly differentiated SCC (2.89 ± 0.63, 56.2 ± 12.9) compared to the well/moderately SCC (3.85 ± 0.81, 77.5 ± 13.9). The homogeneity in poorly differentiated SCC (2.56 ± 0.15 × 10- 1) was higher than that of the well/moderately SCC (2.1 ± 0.18 × 10- 1). CONCLUSIONS: Parameters obtained by histogram and texture analysis of Fs-T2WI may be useful for noninvasive prediction of histological type and grade in head and neck malignancy.

  日本語, 研究論文（学術雑誌）, Radiotherapy combined with cetuximab(Bioradiation therapy:BRT)is one of the standard care methods for locally advanced squamous cell carcinoma of the head and neck(LA-SCCHN). Since its introduction in routine clinical practice, there have been a few reports regarding the use of BRT in Japan. To evaluate the safety and efficacy of therapy including cetuximab, a prospective observation study of Japanese patients with SCCHN treated by combination therapy with cetuximab has been launched. We report the scheduled interim appraisal of the safety and treatment compliance in BRT performed for half of the total accruals(90 patients). This study received support from Merck Serono, and was conducted by the Japanese Radiation Oncology Study Group(JROSG). We analyzed 69 cases that were available for analysis among the 90 cases enrolled from August 2013 to May 2015. Data on baseline characteristics, treatment compliance, and the incidence and severity of adverse events were collected. Patients with cancer of the hypopharynx, oropharynx, larynx, and oral cavity were enrolled. Median age was 66(36-83), and 14 patients(20%)were 75 years old or older. 49 patients(71%)had stage ?A disease. The rate of treatment completion, defined as receiving weekly cetuximab of 6 or more courses and radiotherapy dose of 60Gy or more, was 75%, which was lower than expected. Treatment compliance was especially low in elderly patients. The most frequently reported Grade 3 or 4 adverse events were pharyngeal mucositis(58%), radiation dermatitis(42%), and oral mucositis(39%). Respiratory complications such as aspiration pneumonia(5%)and pneumonitis(3%)were higher than previously reported. Therefore, careful respiratory monitoring is necessary for safe treatment. BRT was adopted widely for patients with LA-SCCHN in Japan. However, treatment compliance was slightly lower than expected, and careful observation during treatment is needed. Safety and efficacy after 1 year will be followed up and described in a final report.

  研究論文（学術雑誌）, IgG4-related disease is a new clinical entity frequently associated with swelling of the submandibular glands (SMGs). The long-term outcome of SMG swelling without steroid therapy remains unknown.
  
  To examine whether swollen SMGs spontaneously regress without steroid therapy in the context of IgG4-related disease and to identify biomarkers that can predict the spontaneous regression of SMG swelling.
  
  The SMG volume of 49 patients diagnosed with IgG4-related disease was calculated by measuring the axial and coronal planes of computed tomography scans. The change in SMG volume over time was measured and examined by treatment regimen, clinical data, and serum complement level.
  
  We found 28 of 49 (57%) IgG4-related disease patients to have swollen SMGs, with 15 of 20 (75%) of the swollen SMGs regressing without steroid therapy. The time required for the SMGs swelling to regress was significantly shorter in the steroid therapy group than in the no-steroid therapy group. Serum complement components at the initial visit were significantly lower in the regressed SMG group than in the nonregressed SMG group.
  
  We observed 75% of swollen SMGs spontaneously regressed in patients with IgG4-related disease. The time required for the swollen SMGs to regress was longer in patients without steroid therapy than in those with steroid therapy. Serum complement level could be used as a predictor for the spontaneous regression of swollen SMGs in patients with IgG4-related disease.

We analyzed the treatment outcomes and safety of concomitant chemoradiotherapy (CCRT), especially with a combination of docetaxel, cisplatin and 5FU (TPF), for local advanced external auditory canal squamous cell carcinomas. In addition, we analyzed the correlation between tumor invasion site and prognosis. The study comprised 21 patients with the following criteria: (1) external auditory canal squamous cell carcinomas which were subject to radical treatment at Hokkaido University Hospital between 2007 and 2017, and (2) T3–4 classified according to the University of Pittsburg system. As a result, tumor invasion into the dura or temporomandibular joint was associated with neck lymph node metastasis, and tumor invasion into the temporomandibular joint was associated with local recurrence. The 2-year overall survival rate (OS) and 2-year local control rate (LC) were 61.1％ and 52.1％ in all patients, respectively. In patients treated with CCRT, the 2-year OS was 85.7％ in CCRT with TPF and 25.0％ in CCRT with others, and the 2-year LC was 57.1％ in CCRT with TPF and 25.0％ in CCRT with others. Grade 3︲4 leucopenia and neutropenia occurred in 55％ and 45％ of patients treated with CCRT with TPF, respectively. CCRT with TPF shows high efficacy and safety for local advanced external auditory canal squamous cell carcinomas.

  英語, 研究論文（学術雑誌）, For stage I/II tongue cancer patients, it is controversial whether prophylactic neck dissection should be performed with partial glossectomy. Based on the evidence of the primary tumor's depth of invasion as a predictive factor of occult lymph node metastases and a prognostic factor of disease-free survival, randomized phase III trial was initiated in November 2017 to evaluate the omission value for prophylactic neck dissection for stage I/II tongue cancer with 3-10 mm of depth of invasion. In 5 years, 440 patients will be accrued from 28 institutions. The primary end point of the study is the overall survival, whereas the secondary end points are relapse-free survival, local relapse-free survival, proportion of unresectable relapse and of cervical lymph node relapse, post-operative function (paralysis of the accessory and facial nerves and subjective symptoms) and adverse events. This trial has been registered with the UMIN Clinical Trials Registry (registration number: UMIN000030098; http://www.umin.ac.jp/ctr/index.htm).

  英語, 研究論文（学術雑誌）, AIM: To assess potential prognostic factors in pharynx squamous cell carcinoma (SCC) patients by quantitative morphological and intratumoural characteristics obtained by 2-[18F]-fluoro-2-deoxy-d-glucose positron-emission tomography/computed tomography (FDG-PET/CT). MATERIALS AND METHODS: The cases of 54 patients with pharynx SCC who underwent chemoradiation therapy were analysed retrospectively. Using their FDG-PET data, the quantitative morphological and intratumoural characteristics of 14 parameters were calculated. The progression-free survival (PFS) and overall survival (OS) information was obtained from patient medical records. Univariate and multivariate analyses were performed to assess the 14 quantitative parameters as well as the T-stage, N-stage, and tumour location data for their relation to PFS and OS. When an independent predictor was suggested in the multivariate analysis, the parameter was further assessed using the Kaplan-Meier method. RESULTS: In the assessment of PFS, the univariate and multivariate analyses indicated the following as independent predictors: the texture parameter of homogeneity and the morphological parameter of sphericity. In the Kaplan-Meier analysis, the PFS rate was significantly improved in the patients who had both a higher value of homogeneity (p=0.01) and a higher value of sphericity (p=0.002). With the combined use of homogeneity and sphericity, the patients with different PFS rates could be divided more clearly. CONCLUSION: The quantitative parameters of homogeneity and sphericity obtained by FDG-PET can be useful for the prediction of the PFS of pharynx SCC patients, especially when used in combination.

  英語, 研究論文（学術雑誌）, : TRIM29 (tripartite motif-containing protein 29) is a TRIM family protein that has been implicated in breast, colorectal, and pancreatic cancers. However, its role in stratified squamous epithelial cells and tumors has not been elucidated. Here, we investigate the expression of TRIM29 in cutaneous head and neck squamous cell carcinomas (SCC) and its functions in the tumorigenesis of such cancers. TRIM29 expression was lower in malignant SCC lesions than in adjacent normal epithelial tissue or benign tumors. Lower expression of TRIM29 was associated with higher SCC invasiveness. Primary tumors of cutaneous SCC showed aberrant hypermethylation of TRIM29. Depletion of TRIM29 increased cancer cell migration and invasion; conversely, overexpression of TRIM29 suppressed these. Comprehensive proteomics and immunoprecipitation analyses identified keratins and keratin-interacting protein FAM83H as TRIM29 interactors. Knockdown of TRIM29 led to ectopic keratin localization of keratinocytes. In primary tumors, lower TRIM29 expression correlated with the altered expression of keratins. Our findings reveal an unexpected role for TRIM29 in regulating the distribution of keratins, as well as in the migration and invasion of SCC. They also suggest that the TRIM29-keratin axis could serve as a diagnostic and prognostic marker in stratified epithelial tumors and may provide a target for SCC therapeutics. SIGNIFICANCE: These findings identify TRIM29 as a novel diagnostic and prognostic marker in stratified epithelial tissues.

  英語, 研究論文（学術雑誌）, Matrix metalloproteinase (MMP)-9 is thought to be involved in the etiopathogenesis of chronic rhinosinusitis (CRS) with nasal polyps and cleaves collagen IV, causing hyperpermeability of the basement membrane within mucosal tissue. It is known that MMP-9 expression is negatively affected by sirtuin (SIRT)-1 in human monocytotic cells, retinal endothelial cells, and epithelial carcinoma cells. However, it is unknown which factors affect MMP-9 expression and activity in human nasal epithelial cells (HNECs). To examine factors affecting MMP-9 expression and activity in HNECs, HNECs were stimulated with Toll-like receptor (TLR) agonists, followed by quantitative PCR, immunofluorescence, and zymography to examine MMP-9 expression and activity. MMP-9 expression was evaluated in sinonasal tissue of control subjects without CRS, and patients with CRS without nasal polyps and those with CRS with nasal polyps, in relation to the expression of SIRT1 using a tissue microarray. The effect of SIRT1 stimulation/inhibition on MMP-9 expression in HNECs was also tested. TLR3 agonists increased MMP-9 mRNA expression (473 fold, P = 0.0198) and activity (20.4-fold, P < 0.05). SIRT1 activation or inhibition reciprocally affected MMP-9 expression in the presence of TLR3 agonists. MMP-9 and SIRT1 expression within the epithelial layer of sinonasal tissue was inversely correlated only in patients with CRS but not in control subjects. TLR3 agonists increased MMP-9 expression and activity in HNECs, and the effect was abolished in the presence of SIRT1 activation. SIRT1 and MMP-9 expression was inversely correlated in CRS tissue, supporting SIRT1 as a possible therapeutic target for nasal polyp formation.

  英語, 研究論文（学術雑誌）, Objective: Although elevated anti-mumps IgM antibody levels were reported in 5.7%–7.2% of Japanese patients with sudden sensorineural hearing loss (SSNHL), there were several reports of false-positive cases, such as the continually IgM positive case and the IgM positive case in normal adults. To improve specificity, the new enzyme immuno assay (EIA) anti-mumps IgM antibody measurement kit was introduced in December 2009. This study re-examined the frequency of anti-mumps IgM antibody test positivity with SSNHL using the new measurement kit and compared the results with those from a previous report that used old kit. Methods: This is a retrospective multi-institutional study involving patients diagnosed with SSNHL who exhibited the anti-mumps IgM antibody. We compared the positive rate of anti-mumps IgM antibody and the annual average number of mumps cases per sentinel in Hokkaido between the patients in the present study and patients previously evaluated. Results: Overall, 100 patients with SSNHL were enrolled. One case (1.0%) was positive for anti-mumps IgM antibody. Of the 69 patients evaluated in the previous study, 5 cases (7.2%) were positive for anti-mumps IgM antibody. The positive rate of the anti-mumps IgM antibody in the present cases was significantly lower than that previously reported (p = 0.042). The annual average number of mumps cases per sentinel in Hokkaido of the present and previous surveillance period was 34.47 and 42.77, respectively
  no significant difference was seen in these data (p = 0.4519). Conclusion: The present study revealed that 1.0% of SSNHL was positive for the anti-mumps IgM antibody using the new EIA-IgM measurement kit. After the introduction of the new EIA-IgM measurement kit, anti-mumps IgM antibody positive rate with SSNHL significantly decreased, indicating that the proportion of asymptomatic mumps among etiology of SSNHL may be lower than those previously reported.

  英語, 研究論文（学術雑誌）, Background: To investigate the utility of quantitative morphological and intratumoral characteristics obtained by 18F-fluorodeoxyglucose positron-emission tomography/computed tomography (FDG-PET/CT) for the prediction of treatment outcome in patients with nasal or paranasal cavity squamous cell carcinoma (SCC). Methods: Twenty-four patients with nasal or paranasal cavity SCC who received curative non-surgical therapy (a combination of super-selective arterial cisplatin infusion and radiotherapy) were retrospectively analyzed. From pre-treatment FDG-PET data, a total of 13 parameters of quantitative morphological characteristics (tumor volume, surface area and sphericity), intratumoral characteristics (the maximum and mean standard uptake value, three intratumoral histogram and four textural parameters) and total lesion glycolysis (TLG) were respectively calculated. Information regarding the treatment outcome was determined from the histological diagnosis or clinical follow-up. Each of the 13 quantitative parameters as well as T- and N-stage was assessed for its relation to treatment outcome of local control or failure. Results: In univariate analysis, significant differences in surface area and sphericity between the local control and failure groups were observed. The receiver operating characteristic (ROC) curve analysis showed that sphericity had the highest accuracy of 0.88. In the multivariate analysis, sphericity was revealed as an independent predictor of the local control or failure. Conclusions: The quantitative parameters of sphericity are useful to predict the treatment outcome in patients with nasal or paranasal SCC.

  英語, 研究論文（学術雑誌）, INTRODUCTION: Lenvatinib, an oral molecular targeted drug, is used to treat patients with unresectable or advanced thyroid carcinoma that is refractory to radioiodine treatment. Effective methods for evaluating molecular targeted drugs are a critical unmet need owing to their expensive costs and unique adverse events. The aim of this study is to determine whether 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/CT at 1 week after commencing lenvatinib can predict treatment outcomes. DESIGN AND METHODS: This study is planned as a non-randomised single-arm multicentre study; patients with pathologically confirmed differentiated thyroid carcinoma (DTC) with lesions that are refractory to radioiodine treatment are eligible. The main exclusion criteria are medullary or anaplastic carcinoma, prior treatment with chemotherapy, poor general condition and thromboembolism-requiring treatment. Patients to be included in the study will be treated with lenvatinib and undergo FDG-PET/CT examination twice: before and 1 week after the initiation of treatment. Contrast-enhanced CT, the gold standard for evaluation, will be performed at least 4 weeks after the initiation of treatment. The primary objective is to evaluate the ability of the lesion maximum standard uptake value for FDG PET/CT performed 1 week after the initiation of treatment to predict outcomes compared with the response evaluation obtained via contrast-enhanced CT performed at least 4 weeks after the initiation of treatment. ETHICS AND DISSEMINATION: This study is conducted in accordance with the Declaration of Helsinki and has received ethical approval from the institutional review board of the Hokkaido University Hospital (approval number: 015-402). The results of this study will be disseminated through a presentation at a conference and the publication of the data in a peer-reviewed journal. The study will be implemented and reported in line with the SPIRIT statement. TRIAL REGISTRATION NUMBER: UMIN000022592.

  英語, 研究論文（学術雑誌）, BACKGROUND: The purpose was to compare survival differences between patients with external auditory canal (EAC) cancer treated according to the University of Pittsburgh modified TNM staging system and those treated in accordance with the 8th edition of the American Joint Committee on Cancer (AJCC) staging manual on the TNM staging system for cutaneous cancers of the head and neck. METHODS: We performed a retrospective, single-institution review of 60 patients with EAC cancer treated with curative intent between September 2002 and March 2018. Survival outcomes were measured on the basis of the two staging systems. RESULTS: The C-index values for the overall survival (OS) rate revealed that the University of Pittsburgh staging system had higher prognostic accuracy than the 8th edition of the AJCC staging system. Univariable and multivariable analysis showed that T classification according to the University of Pittsburgh staging system was an independent predictor of the OS rate (hazard ratio 5.25; 95% confidence interval 1.38-24.9; P = 0.015). Meanwhile, the AJCC staging system could not differentiate T2 from T3-4 cancers. CONCLUSION: The University of Pittsburgh staging system for patients with EAC cancer is a valuable tool for use in clinical decision-making and predicting survival outcome.

  英語, 研究論文（学術雑誌）, Background: The mechanism underlying the malignant transformation of inverted papilloma (IP) has not yet been elucidated. Methods: To clarify the genes responsible for the malignant transformation, we analyzed 10 cases of IP, 8 of IP with dysplasia, and 11 of squamous cell carcinoma (SCC) by targeted amplicon sequencing. Results: The number of mutant genes increased in the order of IP <
  dysplasia <
  SCC. Significant differences were observed in the mutation rates of three genes (KRAS, APC and STK11) in particular. TP53 was altered frequently in each group and might be involved in malignant transformation based on to the site of the mutation. A comparison of the genetic variants by region of IP tissue among patients with IP alone, and those with dysplasia or SCC revealed significant differences in the mutation rate of the KRAS gene. Conclusion: Identification of genetic mutations in KRAS is effective for predicting the malignant transformation of IP.

  英語, 研究論文（学術雑誌）, Background: The revised 8th edition of the AJCC/UICC staging system was released in January 2017, and depth of invasion (DOI) was added to the new criteria for T classification in oral cavity cancer. In this study, we evaluated whether the 8th edition presents the prognosis and risk of nodal metastasis in patients with squamous cell carcinoma of tongue more accurately than did the 7th edition. Methods: The data for 112 patients were obtained and reclassified based on the criteria presented in the 8th edition. Results: Seven patients previously staged as T1 based on the criteria in the 7th edition were reclassified as T2 based on the 8th edition, while 19 T2 patients were reclassified as T3, and 9 T4a patients were reclassified as T3. T3 in the 8th edition represents a homogenous population showing the same prognosis, while T2 in the 8th edition represents a heterogenous population. Nodal metastasis was significantly correlated with T classification in both editions and DOI. However, neither the T classification in the 7th or 8th edition, nor DOI could predict the probability of potential nodal metastasis in patients with cN0 disease. Conclusions: The classification on T3 in the 8th edition can be seen as reasonable with regard to prognosis. Nodal metastasis was significantly correlated with T classification and DOI
  however, the probability of subsequent nodal metastasis in patients with T2N0 was almost same for the criteria in the 7th and 8th editions, therefore, the same careful management as before is required for patients with N0 disease.

  英語, 研究論文（学術雑誌）, Objective:The purpose was to explore the presence of myeloperoxidase (MPO)-deoxyribonucleic acid (DNA) complex as a surrogate marker of neutrophil extracellular traps (NETs) in the middle ear fluid, and to clarify the correlation between its quantifiable level and hearing outcome in patients with otitis media associated with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV).Study Design:Prospective study.Setting:Tertiary referral center.Patients:Nine AAV patients presenting with otitis media.Intervention:Collection of the fluid samples from middle ear.Main Outcome Measure:The quantifiable levels of MPO-DNA complex using an enzyme-linked immunosorbent assay.Results:The quantifiable levels of MPO-DNA complex in patients with AAV were significantly higher than those in controls (p <
  0.001). In particular, both ANCA-positive and-negative cases indicated higher levels of MPO-DNA complex compared with the controls (p = 0.004 and p = 0.006, respectively). The significant negative correlations were observed between the level of MPO-DNA complex and the functional hearing values for air (r =-0.82, p = 0.009) and bone conduction (r =-0.73, p = 0.028), respectively.Conclusion:This analysis is the first to reveal the presence of elevated levels of MPO-DNA complex in the middle ear fluid, suggesting the pathogenic role of NETs in otitis media associated with AAV. NETs may be a valuable biomarker for use in clinical decision-making and predicting hearing outcome, regardless of ANCA status.

  日本語, 研究論文（学術雑誌）, Objective: Aortitis syndrome with bilateral canal paresis: a case report. Patient: A 48-year-old man with aortitis syndrome is presented. The patient had no history of vertigo or dizziness. Result: The patient experienced hearing loss on the left side and dizziness during the investigation for fever of an unknown origin. Sensorineural hearing loss on the left side and nystagmus beating toward the right side were detected with otological examination. Furthermore, a thoracic and abdominal enhanced CT scan revealed a thickened aorta wall, and the patient was diagnosed as having aortitis syndrome. The inner ear disorders were considered to be related to the aortitis syndrome and corticosteroids were administered. Hearing loss was completely restored, but oscillopsia during head movements persisted. A monothermal caloric test showed bilateral canal paresis. Both cervical and ocular VEMP showed no response bilaterally, indicating the dysfunction associated with bilateral otoliths. The results of a video head impulse test revealed decrease in the gain of the vestibuleocular reflex and appearance of catch-up saccade bilaterally, indicating bilateral canal paresis. Conclusion: In this case, the inner ear disorder was considered to be related to the patient's aortitis syndrome. Although hearing loss improved, vestibular impairment persisted. Bilateral canal paresis was demonstrated by vHIT, as well as the caloric test.

  英語, 研究論文（学術雑誌）, Background: The standard of care for first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) is combination treatment with platinum, 5-FU and cetuximab (PFE). However, this regimen requires hospitalization to ensure proper hydration and continuous infusion of 5-FU, and causes severe nausea and anorexia. We evaluated the efficacy and safety of paclitaxel, carboplatin and cetuximab (PCE) as first-line treatment in patients with R/M SCCHN. Patients and methods: Eligibility criteria included recurrent and/or metastatic, histologically proven SCC of the oropharynx, oral cavity, hypopharynx or larynx
  PS 0-1
  adequate organ function
  no suitable local therapy for R/M SCCHN
  and no prior systemic chemotherapy for R/M SCCHN. Chemotherapy consisted of paclitaxel 100 mg/m2 on days 1, 8
  carboplatin area under the blood concentration-time curve 2.5 on days 1, 8, repeated every 3 weeks for up to 6 cycles
  and cetuximab at an initial dose of 400 mg/m2, followed by 250 mg/m2 weekly until disease progression or unacceptable toxicities. Primary end point was overall response rate. Secondary end points were safety, treatment completion rate, progression-free survival, overall survival, and clinical benefit rate. Planned sample size was 45 patients. Results: Forty-seven subjects were accrued from July 2013 to October 2014. Of 45 evaluable, 40 were male
  median age was 63 years
  Eastern Cooperative Oncology Group Performance Status was 0/1 in 23/22 cases
  site was the hypopharynx/ oropharynx/oral cavity/larynx in 17/11/10/7 cases
  and 36/9 cases were smokers/nonsmokers, respectively. Overall response rate, the primary end point, was 40%. Median overall survival was 14.7 months and progression-free survival was 5.2 months. Grade 3/4 adverse events included neutropenia (68%), skin reaction (15%), fatigue (9%) and febrile neutropenia (9%). A potentially treatment-related death occurred in one patient with intestinal pneumonia. Conclusions: The PCE regimen shows promising activity with acceptable toxicity in the outpatient clinic. Further studies are needed to compare PCE with PFE in this population.

  英語, 研究論文（学術雑誌）, PURPOSE: Pharyngo-laryngo-oesophagectomy (PLE) which is mainly indicated for cervical oesophageal cancer or synchronous double cancer of the thoracic oesophagus and the pharynx or larynx, is extremely invasive. Since minimally invasive oesophagectomy (MIE) using video-assisted thoracic surgery has become popular recently, the procedure can be adopted to PLE. Moreover, the use of the prone position (PP) in MIEs has been increasing recently because technical advantages and fewer post-operative complications were reported. To assess the validity of PP, this study compared surgical outcomes of minimally invasive PLE (MIPLE) in PP with that in the left lateral decubitus position (LLDP). PATIENTS AND METHODS: This study enrolled consecutive 15 patients that underwent MIPLE with LLDP (n = 7) or PP (n = 8) between January 1996 and October 2016. The patients' background characteristics, operative findings and post-operative complications were examined. RESULTS: Eligible diseases are 5 cases of cervical oesophageal cancer, 9 cases of synchronous double cancer of the thoracic oesophagus and head and neck and 1 case of cervical oesophageal recurrence of the head-and-neck cancer. The patients' background characteristics were not significantly different. During surgery, thoracic blood loss was significantly lower in PP than in LLDP (P = 0.0487). Other operative findings and post-operative complications were not significantly different between the two groups. CONCLUSIONS: In MIPLE, the PP could reduce blood loss due to the two-lung ventilation under artificial pneumothorax and was associated with lower surgical stress than LLDP.

  研究論文（学術雑誌）, © 2017 Wiley Periodicals, Inc. Background: We are currently undertaking a multi-institutional prospective trial of the superselective intra-arterial infusion of high-dose cisplatin with concomitant radiotherapy for patients with T4aN0M0 or T4bN0M0 locally advanced maxillary sinus squamous cell carcinomas (SCC). We herein report the results of the dose-finding phase. Methods: The dose-finding phase sought to evaluate the incidence of dose-limiting toxicities and determine the recommended number of cycles of the intra-arterial infusion of cisplatin. In this phase, 100 mg/m2 of cisplatin was administered intra-arterially weekly for 7 weeks with concomitant radiotherapy (70 Gy). Results: All 18 patients received a full dose of radiotherapy. The number of cycles of cisplatin was 7 in 13 patients and 6 in 5 patients. The dose-limiting toxicities were observed in 5 patients. Conclusion: These results indicated that this therapy is safe and well-tolerated at 7 cycles of cisplatin, which was determined to be the recommended number of cycles for locally advanced maxillary sinus SCC.

  英語, 研究論文（学術雑誌）, Objective: We aimed to evaluate the clinical features and treatment outcomes for patients with idiopathic and secondary external auditory canal cholesteatoma (EACC), and to validate the treatment strategy from the perspective of hearing as well as etiology and staging. Study Design: Retrospective case series. Setting: Tertiary referral center and affiliated hospitals. Patients: Fifty-eight patients with idiopathic EACC and 14 patients with secondary EACC. Intervention: Conservative management and surgery. Main Outcome Measure: Air conduction (AC) pure-tone averages (PTAs) and mean air-bone gaps (ABGs). Results: There were no significant differences between hearing values before and after conservative management for idiopathic EACC patients with stages I-III, indicating that hearing abilities were preserved. For idiopathic EACC patients with stage IV disease treated with surgery, the AC PTA threshold and mean ABG significantly improved from a preoperative value of 60.3 dB HL to a postoperative value of 32.4 dB HL (p = 0.013), and from 34.3 to 9.5 dB HL (p <
  0.001), respectively. For secondary EACC, the AC PTA threshold and mean ABG significantly improved from a preoperative value of 49.5 dB HL to a postoperative value of 23.2 dB HL (p <
  0.001), and from 31.4 to 6.7 dB HL (p <
  0.001), respectively. Conclusion: The treatment modalities should be selected based on the perspective of hearing as well as the extent of disease and etiology. The early lesions can be treated conservatively, whereas the advanced lesions or cases refractory to conservative management require complete surgical removal of EACC.

  英語, 研究論文（学術雑誌）, PURPOSE: To evaluate the diagnostic power of hybrid intravoxel incoherent motion (IVIM)-diffusion kurtosis imaging (DKI) model parameters in pretreatment for the prediction of future distant metastasis in head and neck squamous cell carcinoma (HNSCC) patients. MATERIALS AND METHODS: We retrospectively evaluated 49 HNSCC patients who underwent curative chemoradiation therapy. Diffusion-weighted image (DWI) acquired by single-shot spin-echo echo-planar imaging with 12 b-values (0-2000) was performed in all patients before any treatment. We calculated the IVIM-DKI parameters and the conventional apparent diffusion coefficient (ADC) in the ROI placed on the primary lesion. The presence of future distant metastasis was determined by histological findings or clinical follow-up. RESULTS: A univariate analysis revealed significant differences between the patients with distant metastasis and those without in slow diffusion coefficient (D) and kurtosis value (K). Highest diagnostic accuracy was obtained by the D value. In addition, a multivariate analysis revealed that the D value was an independent predictor of future distant metastasis. CONCLUSION: The D and K values obtained by this hybrid IVIM-DKI model can be one of the diagnostic tools for the prediction of future distant metastasis in HNSCC patients.

  研究論文（学術雑誌）, Due to various functional disorders and adverse events with head and neck cancer treatment, the QOL of cancer survivors markedly decreases. In many cases, there is a gradual improvement in QOL, though patients experience various discomforts daily. A critical issue is how long long-term survivors can continue to manage their oral condition. Since 2012, cooperating cancer dentists have been registered and presently there are more than 14,000 such dentists in Japan, creating a framework for referring such cancer patients to dentists in general practice. In 2011, for patients who were treated from 2007 to 2010, we performed a survey of continued oral management after discharge from Hokkaido University Hospital. After discharge, 34.3% of cases continued oral management, but when limited to patients in the care of general practice dentists, the rate was only 7.5%. In this study of patients from 2011 to 2016, the patients who continued oral management after discharge and the patients in the care of general practice dentists were higher, at 70.5% and 40.4%. It is essential that appropriate oral management in cooperation with local dental clinics is continued to improve the QOL of head and neck cancer patients.

  日本語, 研究論文（学術雑誌）, Ten patients diagnosed with adductor spasmodic dysphonia (ADSD) read aloud eight homonyms while ten healthy university students who speak standard Japanese judged the word meanings. Results of the assessments revealed that the intra-evaluator matching was 88.6%, with 19/80 samples (23.8%) misjudged by more than half of the evaluators. These samples were classified as either 1) voiced/unvoiced or 2) an accent kernel position. Homonyms that were constructed from serial voiced syllables (11/19 samples) or with the accent kernel position in the second mora (13/19 samples) tended to be misjudged. Difficulty of speech in ADSD patients affects not only “voice” disorders but also “speech” disorders, including voice pitch adjustment, and these adjustment errors may lead to low speech intelligibility.

  英語, Parotid gland tumor with facial nerve paralysis is strongly suggestive of a malignant tumor. However, several case reports have documented benign tumors of the parotid gland with facial nerve paralysis. Here, we report a case of oncocytoma of the parotid gland with facial nerve paralysis. A 61-year-old male presented with pain in his right parotid gland. Physical examination demonstrated the presence of a right parotid gland tumor and ipsilateral facial nerve paralysis of House-Brackmann (HB) grade III. Due to the facial nerve paralysis, a malignant tumor of the parotid gland was suspected and right parotidectomy was performed. Oncocytoma was confirmed histopathologically. The facial nerve paralysis was resolved 2 months after surgery. During the follow-up period (one and a half years), no recurrence was observed. As the tumor showed a distinctive dumbbell shape and increased somewhat due to inflammation (i.e., infection), the facial nerve was pinched by the enlarged tumor. Ischemia and strangulation of the nerve were considered to be the cause of the facial nerve paralysis associated with the benign tumor in this case.

  英語, 研究論文（学術雑誌）, Background The aim of this study was to compare the therapeutic outcomes of total pharyngolaryngectomy with those of concomitant chemoradiotherapy in advanced hypopharyngeal cancer.
  Methods This is a retrospective multi-institutional study. The medical records of 979 patients with hypopharyngeal cancer, who were initially treated between 2006 and 2008, were reviewed. In this study, we matched a group of total pharyngolaryngectomy patients with a second group of chemoradiotherapy patients, according to age, gender, subsite, arytenoid fixation, cartilage invasion, and N classification, and analyzed overall survival, disease-specific survival, and locoregional control rates.
  Results The matched-pair analysis included 254 patients. The 5-year overall survival, disease-specific survival, and locoregional control rates were 58.5% and 53.5% (P = 0.30), 68.9% and 68.0% (P = 0.80), and 82.2% and 63.6% (P < 0.01), respectively, for patients in the total pharyngolaryngectomy and chemoradiotherapy groups. For T4a patients with cartilage invasion, the matched-pair analysis included 46 patients. The 5-year overall survival, disease-specific, and locoregional control rates were 56.5% and 26.0% (P = 0.092), 56.5% and 41.3% (P = 0.629), and 43.0% and 42.5% (P = 0.779), respectively, for patients in the total pharyngolaryngectomy and chemoradiotherapy groups.
  Conclusions The data from this large-scale multi-institutional joint research program of hypopharyngeal cancer in Japan suggest that chemoradiotherapy may provide adequate survival benefit for hypopharyngeal cancer patients with the distinct advantage of larynx preservation. Our data also suggest that chemoradiotherapy is as beneficial as total pharyngolaryngectomy for the local control of locally advanced hypopharyngeal cancer.

  英語, Objective: To reveal the usefulness of T1-weighted (T1W) imaging on diagnostic magnetic resonance (MR) imaging for cholesteatoma. Study Design: A retrospective case review. Setting: Tertiary referral center. Patients: Fifty-three patients (57 ears) suspected to have cholesteatomas and treated (6-82 yr of age). Intervention: Preoperative MR imaging, including non-echo planar (non-EP) diffusion-weighted (DW) and T1W imaging. Main Outcome Measures: Primary outcome measures included the comparison between the diagnostic accuracy for the detection of cholesteatomas using non-EP DW imaging alone (criterion 1) and non-EP DW imaging along with T1W imaging (criterion 2). Diagnostic accuracy was evaluated in each case by comparing MR imaging with surgical findings. Secondary outcome measures included the comparison of the rates of cases showing a high T1W signal between cholesteatomas and noncholesteatomas which showed a high non-EP DW signal. Results: The sensitivity, specificity, and accuracy according to criterion 1 were 93.5, 63.6, and 87.7% and those according to criterion 2 were 89.1, 100, and 91.2%, respectively. Of 43 cholesteatoma cases indicating a high non-EP DW signal, only 2 cases showed a high T1W signal (5%). On the other hand, all four noncholesteatoma cases indicating high non-EP DW signal showed a high T1W signal (100%), and these rates were significantly different ( p<
  0.001). Conclusion: Our results suggest that T1W imaging may aid in the exclusion of false-positive cases on diagnostic non-EP DW MR imaging for cholesteatomas. A combination of non- EP DW and T1W imaging may improve the specificity and accuracy compared with non-EP DW imaging alone.

  英語, 研究論文（学術雑誌）, Atypical adenoma of the thyroid is a rare form of tumor, and its accurate diagnosis prior to surgical resection is difficult as the histological and pathological morphologies are very similar to those of anaplastic thyroid carcinoma (ATC), and its anaplastic transformation remains to be elucidated. We reported a case of a 75-year-old female with a thyroid isthmus nodule diagnosed repeatedly by FNAC as anaplastic carcinoma. Both the first and second FNAC specimen slides showed a large number of scattered or aggregated atypical cells consisting of large, pleomorphic nuclei with irregular membranes, chromatin clumps and prominent nucleoli. The morphology of the surgical specimen was similar to that of an anaplastic carcinoma and although it showed signs of transition from a normal follicular epithelium, there was no invasive growth or mitosis. This lesion was diagnosed as an atypical adenoma, and a papillary carcinoma was also present in the right lobe of the thyroid. Here we evaluate the molecular features of atypical adenomas in comparison with 9 ATC samples, and discuss whether or not atypical adenomas represent a form of premalignant lesion. Ki-67 expression was found to be very low in atypical adenomas whereas all ATC samples showed high levels of Ki-67 expression. Epithelial-mesenchymal transition (EMT) marker expression suggested that atypical adenomas maintain their epithelial phenotype to a higher degree than do ATCs. Differential diagnosis between ATC and atypical adenoma is difficult by cytological and histological methods alone, and Ki-67 and EMT marker expression may support the diagnosis.

  INTERNATIONAL JOURNAL OF CLINICAL ONCOLOGY, 22, 4, 682, 689, SPRINGER JAPAN KK, 2017年08月, ［査読有り］
  英語, 研究論文（学術雑誌）, Background Several studies have demonstrated that the seventh edition of the American Joint Committee on Cancer/American Joint Committee on Cancer (AJCC/UICC) TNM staging system does not consistently distinguish between prognostic subgroups for human papillomavirus (HPV)-mediated oropharyngeal squamous cell carcinoma (OPSCC). The eighth edition of the AJCC/UICC TNM staging system came into effect for use with HPV-mediated OPSCC on or after 1 January 2017. This study confirms that the eighth edition of the AJCC/UICC TNM staging system for HPV-mediated OPSCC accurately reflects disease outcomes.
  Patients and methods We retrospectively analyzed 195 patients with OPSCC treated at Hokkaido University Hospital, Sapporo, Japan between 1998 and 2015. HPV status was evaluated by immunohistochemical analysis of p16.
  Results Of the 195 OPSCC patients evaluated, 111 (56.9%) were p16 positive and 84 (43.1%) were p16 negative. The 3-year overall survival rate (OS) was significantly lower in the p16-negative patients with stage III-IV in comparison with those with stage I-II (55.0 vs. 93.1%, respectively; p < 0.01). The 3-year OS did not differ significantly between stage I-II and stage III-IV in the p16-positive patients (86.7 vs 87.7%). According to the eighth edition of the AJCC/UICC TNM staging system, stage I-II and stage III can be differentiated on the basis of the 3-year OS in the p16-positive patients (90.9 vs 70.2%, respectively; p < 0.01).
  Conclusions The seventh edition of the AJCC/UICC TNM staging system is suitable for use with p16-negative patients; however, it does not effectively discriminate between p16-positive patients. Therefore, the eighth edition of the AJCC/UICC TNM staging system is more suitable for HPV-mediated OPSCC in Japan.

  英語, 研究論文（学術雑誌）, Objective: The first revision of "Japanese Clinical Practice Guideline for Head and Neck Cancer" was made in 2013 by the clinical practice guideline committee of Japan Society for Head and Neck Cancer, in response to the revision of the TNM classification.Methods: 34 CQs (Clinical Questions) were newly adopted to describe the diagnosis and treatment methods currently considered most appropriate, and offered recommendation grade made by the consensus of the committee. A comprehensive literature search was performed for studies published between 2001 and 2012 using PubMed. Qualified studies were analyzed and the results were evaluated, consolidated and codified by all the committee members.Results: Elective neck dissection (ND) does contribute to improvement in survival and should be performed for patients with high-risk tongue cancer. At present, no research has clearly demonstrated the utility of superselective arterial infusion chemotherapy. However, depending on the site and stage of the cancer, combination with radiotherapy may be useful for preserving organ function or improving survival rate. Concurrent CDDP chemotherapy and adjuvant radiotherapy contributes to improvement of survival rate as an adjuvant therapy for advanced squamous cell carcinoma of the head and neck in patients at high risk of recurrence. The anti-EGFR antibody cetuximab (Cmab) has an additive effect with radiotherapy. However, the indication must be carefully considered since this treatment has not been compared with the standard treatment of chemoradiotherapy. Cmab has been shown to have an additive effect with chemotherapy (CDDP/5-FU) in patients with unresectable metastatic or recurrent cancer. Preoperative and postoperative oral care may reduce the risk of postoperative complications such as surgical wound infection and pneumonia in head and neck cancers. Rehabilitation soon after ND for cervical lymph node metastasis is recommended for maintaining and restoring shoulder function.Conclusions: In this article, we described most relevant guidelines and CQs for the diagnosis and treatment of head and neck cancer in Japan. These guidelines are not intended to govern therapies that are not shown here, but rather aim to be used as a guide in searching for the most appropriate treatment for individual patient.

  英語, 研究論文（学術雑誌）, OBJECTIVES: The aim of this study was to evaluate speech in patients with adductor spasmodic dysphonia (ADSD) by perceptual evaluations and acoustic measures, and to examine the reliability and validity of these measures. METHODS: Twenty-four patients with ADSD and 24 healthy volunteers were included in the study. Speech materials consisted of three sentences constructed from serial voiced syllables to elicit abductor voice breaks. Three otolaryngologists rated the degree of voice symptoms using a visual analog scale (VAS). VAS sheets with five 100-mm horizontal lines were given to each rater. The ends of the lines were labeled normal vs severe, and the five lines were labeled as overall severity of each of the four speech symptoms (strangulation, interruption, tremor and strained speech). Nine words were selected for acoustic analysis, and abnormal acoustic events were classified into one of the three categories. To evaluate the intra- and inter-rater and intermeasurer reliabilities of the VAS scores or acoustic measures, Pearson r correlations were calculated. To examine the validity of perceptual evaluations and acoustic measures, the sensitivity and the specificity were calculated. RESULTS: Pearson r correlation coefficients for overall severity showed the highest intra- and inter-rater reliabilities. For acoustic events, the intrameasurer reliabilities were r = .645 (frequency shifts), r = .969 (aperiodic segments), and r = 1.0 (phonation breaks), and the intermeasurer reliability ranged from r = .102 to r = 1.0. Perceptual evaluation showed high sensitivity (91.7%) and specificity (100%), whereas acoustic analysis showed low sensitivity (70.8%) and high specificity (100%). CONCLUSION: Both perceptual evaluation and acoustic measures alone were found likely to overlook patients with true ADSD.

  英語, 研究論文（学術雑誌）, Background: Osteoradionecrosis (ORN) of the hyoid bone sometimes induces severe front neck infection and can cause laryngeal stenosis and carotid rupture. Although ORN of the hyoid bone is known to be a complication of chemoradiotherapy for head and neck cancer, there has been no basis for its evaluation. Our purpose is to present the clinical and MR imaging features of ORN of the hyoid bone.
  Methods: The study group comprised patients with advanced oropharyngeal cancer treated with targeted intra-arterial cisplatin infusion with concomitant radiotherapy. ORN of the hyoid bone was identified on the basis of decreased signal intensity of the bone marrow on T1WI images. Signal intensity on T2WI images was used to distinguish between inflammation and fibrosis.
  Results: A total of 39 pre-treatment MR images and follow-up MR images were reviewed. ORN of the hyoid bone were detected in 30% of patients after treatment, with 23% of them showing inflammation and 7.7% fibrosis. Two patients developed severe neck infection and received antibiotics and underwent surgical intervention by tracheostomy and resection of the hyoid bone.
  Conclusion: Our MR imaging study showed that ORN of the hyoid bone is not particularly rare in patients with oropharyngeal cancer treated with chemoradiotherapy. Clinicians should evaluate images carefully to prevent the development of severe complication due to infection associated with ORN of the hyoid bone.

  英語, 研究論文（学術雑誌）, Inverted papilloma (IP) is a benign tumor occurring in the nasal cavity and paranasal sinuses. It is reported that 5-15% of IPs undergo malignant transformation into squamous cell carcinoma (SCC), and the role of microRNAs (miRNA/miR) in this process remains to be elucidated. In the present study, whole miRNA profiles using samples of IP and SCC were investigated, in order to detect the function of miRNA in the carcinogenesis of IP. Samples from IPs (n=5) and SCC lesions (n=5), which arose from IPs, were used for miRNA analysis. A total of 200 miRNAs exhibited a > 2-fold differential expression between IP and SCC. miR-296-3p was markedly upregulated in SCC with a 23-fold difference. Computational analysis indicated that miR-296-3p targeted PTEN, which regulates the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway and PTEN is involved in the carcinogenesis of SCC. miR-296-3p directly regulated PTEN expression in head and neck cancer cells, with PTEN protein levels decreased in 4/19 the SCCs (21.0%), as compared with those in the IPs (76.4%). Positive p21 staining was observed in 64.7% of IPs; this was a significantly increased rate compared with that for SCCs (26.3%, P=0.0086). The results of the present study indicated that there were marked changes in the miRNA expression signature during the malignant transition. miR-296-3p may serve an important role in the malignant transformation of IPs via the regulation of PTEN, combined with the subsequent inhibition of the PI3K/Akt signaling pathway, and may be a novel agent for cancer prevention.

  英語, 研究論文（学術雑誌）, Objective: A recent study identified a survival benefit with prophylactic neck dissection (ND) at the time of primary surgery as compared with watchful waiting followed by therapeutic neck dissection for nodal relapse, in patients with cN0 oral squamous cell carcinoma (OSCC). Alternative management of cN0 neck cancer is recommended to minimize the adverse effects of ND, indicating the need for sentinel node biopsy (SNB) and limited neck dissection. We conducted a multicenter Phase II study to examine the feasibility of SNB for clinically N0 OSCC.
  Methods: Previously untreated N0 OSCC patients (n = 57) with clinical late-T2 or T3 tumors were enrolled across 10 institutions. SNB navigated with multislice frozen section analysis of sentinel nodes (SNs) and SNB supported sentinel node lymphatic basin dissection (SN basin dissection) were performed in a one-stage procedure. The endpoint was to investigate the rate of false-negative metastases after SN basin dissection and SNB alone.
  Results: Most tumors were late-T2 lesions (n = 50; 87.7%). SNs were identified in all patients. A total of 196 SNs were detected. Among these SNs, 35 (17.8%) were positive for metastasis (9 in level I, 12 in level II, 12 in level III, 1 in level V and 2 in the contralateral region of the neck). The false-negative rate of SNB supported by SN basin dissection and SNB alone was 4.5% and 9.1%, respectively. The concordance of the SN status in intraoperative frozen sections with the permanent histopathology was 97.4% (191/196). The sensitivity and specificity of intraoperative pathological evaluation were 85.7% (30/35) and 100% (30/30), respectively. The 3-year overall survival (OS) and disease-free survival was 89.5% and 82.5%, respectively. The OS of SN-negative patients was significantly longer than that of SN-positive patients (P = 0.047).
  Conclusion: The current study verified that SN basin dissection was a useful back-up procedure for SNB performed as a one-stage procedure, showing a low false-negative rate. SNB, alone is an appropriate staging method for patients with clinical N0 staging, and a reliable procedure to determine the appropriate levels for neck dissection. (C) 2016 Elsevier Ireland Ltd.

  英語, 研究論文（学術雑誌）, Type II thyroplasty (TPII) is one of the surgical options offered in the management of adductor spasmodic dysphonia (AdSD); however, there have been no detailed reports of its safety and associated complications during the perioperative period. Our aim was to assess the complications and safety of TPII. TPII was performed for consecutive 15 patients with AdSD from April 2012 through May 2014. We examined retrospectively the perioperative complications, the degree of surgical invasion, and recovery process from surgery. All patients underwent successful surgery under only local anesthesia. Vocal fold erythema was observed in 14 patients and vocal fold edema in 10 patients; however, all of them showed complete resolution within 1 month. No patient experienced severe complications such as acute airway distress or hemorrhage. Fourteen patients were able to have oral from the 1st postoperative morning, with the remaining patient able to have oral intake from the 2nd postoperative day. In addition, no patient experienced aspiration postoperatively. In conclusion, only minor complications were observed in association with TPII in this study. No dysphagia was observed postoperatively, which is an advantage over other treatments. The results of our study suggest that TPII is a safe surgical treatment for AdSD.

  英語, 研究論文（学術雑誌）, We assessed parameters of advanced diffusion weighted imaging (DWI) models for the prediction of the tumor growth rate in 55 head and neck squamous cell carcinoma (HNSCC) patients. The DWI acquisition used single-shot spin-echo echo-planar imaging with 12 b-values (0-2000). We calculated 14 DWI parameters using mono-exponential, bi-exponential, tri-exponential, stretched exponential and diffusion kurtosis imaging models. We directly measured the tumor growth rate from two sets of different-date imaging data. We divided the patients into a discovery group (n = 40) and validation group (n = 15) based on their MR acquisition dates. In the discovery group, we performed univariate and multivariate regression analyses to establish the multiple regression equation for the prediction of the tumor growth rate using diffusion parameters. The equation obtained with the discovery group was applied to the validation group for the confirmation of the equation's accuracy. After the univariate and multivariate regression analyses in the discovery-group patients, the estimated tumor growth rate equation was established by using the significant parameters of intermediate diffusion coefficient D-2 and slow diffusion coefficient D-3 obtained by the tri-exponential model. The discovery group's correlation coefficient between the estimated and directly measured tumor growth rates was 0.74. In the validation group, the correlation coefficient (r = 0.66) and intra-class correlation coefficient (0.65) between the estimated and directly measured tumor growth rates were respectively good. In conclusion, advanced DWI model parameters can be a predictor for determining HNSCC patients' tumor growth rate.

  英語, 研究論文（学術雑誌）, Purpose: To evaluate the detectability of the residual tumour in post-treatment granulation tissue using parameters obtained with an advanced diffusion model in patients with head and neck squamous cell carcinoma (HNSCC) treated by chemoradiation therapy.
  Materials and methods: We retrospectively evaluated 23 patients with HNSCC after the full course of chemoradiation therapy. The diffusion-weighted image (DWI) acquisition used single-shot spin-echo echo-planar imaging with 11 b-values (0-1000). We calculated 10 DWI parameters using a monoexponential model, a bi-exponential model, a stretched exponential model (SEM), a diffusion kurtosis imaging (DKI) model and a statistical diffusion model (SDM) in the region of interest (ROI) placed on the post-treatment granulation tissue. The presence of residual tumour was determined by histological findings or clinical follow-up.
  Results: Among the 23 patients, seven patients were revealed to have residual tumour. The univariate analysis revealed significant differences in six parameters between the patients with and without residual tumour. From the receiver operating characteristic curve analysis, the highest area under curve was detected in the center of the Gaussian distribution of diffusion coefficient (D-s) obtained by the SDM. The multivariate analysis revealed that the D-s and diffusion heterogeneity (alpha) obtained by the SEM were predictors for the presence of residual tumour.
  Conclusion: DWI parameters obtained by advanced fitting models will be one of the diagnostic tools for the detection of residual tumour. (C) 2017 Elsevier B.V. All rights reserved.

  英語, 研究論文（学術雑誌）, To evaluate the diagnostic value of intravoxel incoherent motion (IVIM) and diffusional kurtosis imaging (DKI) parameters in nasal or sinonasal squamous cell carcinoma (SCC) patients to determine local control/failure.
  Twenty-eight patients were evaluated. MR acquisition used single-shot spin-echo EPI with 12 b-values. Quantitative parameters (mean value, 25th, 50th and 75th percentiles) of IVIM (perfusion fraction f, pseudo-diffusion coefficient D*, and true-diffusion coefficient D), DKI (kurtosis value K, kurtosis corrected diffusion coefficient D-k) and apparent diffusion coefficient (ADC) were calculated. Parameter values at both the pretreatment and early-treatment period, and the percentage change between these two periods were obtained.
  Multivariate logistic regression analysis: the percentage changes of D (mean, 25th, 50th, 75th), K (mean, 50th, 75th), Dk (mean, 25th, 50th), and ADC (mean, 25th, 50th) were predictors of local control. ROC curve analysis: the parameter with the highest accuracy = the percentage change of D value with the histogram 25th percentile (0.93 diagnostic accuracy). Multivariate Cox regression analyses: the percentage changes of D (mean, 25th, 50th), K (mean, 50th, 75th), Dk (mean, 25th, 50th) and ADC (mean, 25th, 50th) are predictors.
  IVIM and DKI parameters, especially the D-value's histogram 25th percentile, are useful for predicting local control.
  Noninvasive assessment of treatment outcome in SCC patients was achieved using IVIM/DKI.
  Several IVIM and DKI parameters can predict the local control.
  Especially, the D-value's histogram 25th percentile has high diagnostic accuracy.

  日本語, 症例は61歳男性で、来院の10年ほど前から右耳下部の腫瘤を自覚していた。某月某日、夜間に右耳下部周囲痛を自覚した。右耳下部に3cm大の圧痛を伴う可動性不良な腫瘤を触知し、右顔面神経麻痺を認めた。CTでは右耳下腺内に造影効果のある辺縁不整の腫瘍を認め、MRIでは腫瘍はT1強調像で低信号、T2強調像では内部不均一で一部高信号を示した。臨床経過と所見から耳下腺悪性腫瘍が疑われ当院紹介となった。エコーでは右耳〜下腺内に30×25mmの内部不均一で一部分葉状の腫瘤を認めた。悪性腫瘍を想定し、顔面神経合併切除での右耳下腺腫瘍全摘術+顔面神経再建術を予定したが、術中所見で良性が予想される場合は顔面神経を温存する方針とした。術中迅速病理検査では、充実部分は周囲に線維性の被膜を伴い、嚢胞壁は異型に乏しい扁平上皮で覆われており、明らかな悪性所見は認めなかった。術中所見と迅速病理結果から良性の可能性が高いと判断し、顔面神経は温存し、耳下腺正常組織を一部含めて腫瘍を顔面神経上下枝の間から摘出した。病理組織学的所見からoncocytomaと最終診断された。術後は鼻翼に軽度の麻痺を認めたが、約2ヵ月後に柳原法40/40点と改善した。術後1年以上経過した現時点で腫瘍再発は認めていない。

  英語, 研究論文（学術雑誌）, Background The aim of this study was to investigate the expression of p53, p16, cyclin D1, epidermal growth factor receptor (EGFR) and Notch1 in temporal bone squamous cell carcinoma (TBSCC) tissue samples by immunohistochemistry (IHC), and to evaluate the association between these biomarkers and clinicopathological features.
  Methods We performed a retrospective, single-institution review of 30 TBSCC patients treated with curative intent between April 2006 and March 2015. All tissue samples were obtained from pretreatment biopsy specimens or surgical specimens and using IHC staining.
  Results Ten patients were categorized as T1, seven as T2, five as T3 and eight as T4. Nine patients had clinically positive lymph node metastasis. The positive expression of p53 and EGFR was significantly associated with T classification (P = 0.042 and P = 0.0039). EGFR expression was significantly more frequent in patients with positive lymph node metastasis compared with patients without node involvement (P = 0.017). In the analysis of the association between protein expression by IHC staining and prognosis, the positive expression of EGFR and Notch1 was significantly correlated with poor survival outcomes in TBSCC (P = 0.015 and P = 0.025)
  Conclusion Overexpression of p53 and EGFR may be valuable biomarkers for identifying individuals at high risk of developing tumors in TBSCC. Furthermore, the positive expression of EGFR was significantly associated with poor survival outcome. Anti-EGFR therapy has potential for use as the treatment modality of choice for advancedstage TBSCC as well as other head and neck squamous cell carcinomas.

  英語, 研究論文（学術雑誌）, Background. The purpose of this study was to analyze the relationship between pretreatment inflammatory markers and the prognosis of patients with oropharyngeal, hypopharyngeal, and laryngeal cancers.
  Methods. The data for 285 patients treated with curative intent by concurrent chemoradiotherapy (CRT) were obtained and their pretreatment inflammatory markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) were calculated.
  Results. Significant relationships were observed between a high NLR and oropharyngeal or hypopharyngeal cancer, T3 to T4, N2b to N3, and clinical stage III to IV, whereas significant relationships were observed between a high LMR and laryngeal cancer, T1 to T2, and clinical stage I to II. With regard to survival outcomes, a high NLR, a high PLR, and a low LMR were all significantly associated with decreases in overall survival OS) and disease-free survival (DFS). Furthermore, multivariate analysis showed that LMR was an independent prognostic factor.
  Conclusion. Pretreatment LMR was found to be an independent prognostic factor for patients with head and neck cancers treated by concurrent CRT. (C) 2016 Wiley Periodicals, Inc.

  英語, 研究論文（学術雑誌）, Purpose: We assessed advanced fitting models of diffusion weighted imaging (DWI) in head/neck squamous cell carcinoma (HNSCC) patients to determine the best goodness of fit and correlations among diffusion parameters. We compared these results with those of dynamic contrast-enhanced (DCE) perfusion parameters.
  Materials and methods: We retrospectively evaluated 32 HNSCC patients (12 sinonasal, 20 pharynx/oral cavity). The DWI acquisition used single-shot spin-echo echo-planar imaging (EPI) with 12 b-values (0 - 2000). We calculated 14 DWI parameters using mono-exponential, bi-exponential, and tri-exponential models, stretched exponential model (SEM) and diffusion kurtosis imaging (DKI) models. We compared each model's goodness of fit using the residual sum of squares (RSS), Akaike Information Criterion (AIC) and Bayesian information criterion (BIC) value. We determined the correlation between each pair of DWI parameters and between each DWI parameter and DCE perfusion parameter.
  Results: The tri-exponential fit's RSS, AIC and BIC values were significantly smaller than those for bi-exponential fit. The RSS, AIC and BIC values of the SEM fit and DKI fit were significantly smaller than mono-exponential model. Significant correlations were observed in 30 pairs (sinonasal cavity) and 31 (sinonasal cavity group) among 91 DWI parameter combinations. Significant correlations were also observed in nine pairs (both sinonasal cavity and pharynx/oral cavity group) among 64 DWI/DCE perfusion parameter pairs, in particular, high positive correlations between the tri-exponential model's intermediate diffusion fraction (f(2)) and the volume of the extracellular extravascular space per unit volume of tissue (v(e)) were observed in both patient groups.
  Conclusion: We identified several correlations between DWI parameters by advanced fitting models and correlations between DWI and DCE parameters. These will help determine HNSCC patients' detailed tissue structures. (C) 2016 Elsevier Inc. All rights reserved.

  英語, 研究論文（学術雑誌）, Vogt-Koyanagi-Harada (VKH) disease is an idiopathic, multi-system autoimmune disorder characterized by bilateral, diffuse granulomatous uveitis associated with neurological, audiovestibular, and dermatological manifestations. The purpose of this study is to investigate vestibular functions in patients with VKH disease. A total of 43 patients with VKH disease in Hokkaido University Hospital were enrolled in this study. Subjective symptoms such as dizziness or vertigo and the results of various vestibular examinations including nystagmus testing, caloric testing, and vestibular-evoked myogenic potential (VEMP) testing were investigated. Eight of 42 patients (19.0%) complained of subjective vestibular symptoms. On the other hand, 12 of 28 patients (42.9%) showed nystagmus, and 7 of 15 patients (46.7%) showed unilateral or bilateral weakness in the caloric test. VEMP testing was performed for 16 patients. Seven (43.8%) and 8 (50.0%) patients were evaluated as abnormal in cervical VEMP and ocular VEMP testing, respectively. The rate of detection of nys-tagmus was significantly higher than that of subjective symptoms. As vestibular dysfunction in patients with VKH disease cannot be detected through history taking alone, nystagmus testing, caloric testing, and VEMP testing should be performed to evaluate vestibular functions associated with VKH disease. It is considered that abnormal VEMP findings are associated with otolith organ dysfunction. (C) 2017 S. Karger AG, Basel

  英語, 研究論文（学術雑誌）, Objective: This study aimed to predict eosinophilic chronic rhinosinusitis prognosis by investigating changes in the blood eosinophil count and other disease biomarkers after surgery.
  Methods: Blood eosinophil numbers and serum interleukin- 5 levels were measured in 22 eosinophilic chronic rhinosinusitis patients before and after functional endoscopic sinus surgery, and compared with equivalent measures in non-eosinophilic chronic rhinosinusitis patients and chronic rhinosinusitis without polyps patients. Differences between well-controlled eosinophilic chronic rhinosinusitis patients and those who experienced recurrence were also assessed.
  Results: Blood eosinophil numbers and serum interleukin- 5 level decreased after surgery in eosinophilic chronic rhinosinusitis patients. In this patient group, blood eosinophil counts before surgery were significantly higher in patients who experienced recurrence (825.7 +/- 26.1 vs 443.9 +/- 76.6 cells/mu l, p < 0.05), and decreased significantly after surgery (825.7 +/- 26.1 vs 76.7 +/- 25.8 cells/mu l, p < 0.05).
  Conclusion: Blood eosinophil numbers may reflect disease severity in eosinophilic chronic rhinosinusitis patients and their prognosis after surgery.

  英語, 研究論文（学術雑誌）, Prophylactic neck dissection (PND) for patients with clinically N0 (cN0) tongue carcinoma remains controversial. We assessed the efficacy of PND for patients with cN0 tongue squamous cell carcinoma (SCC) and investigated the prognostic role of tumor thickness as assessed by diagnostic imaging in predicting the risk of nodal micrometastasis or late nodal recurrence. Eighty-eight patients with cN0 tongue carcinomas underwent surgical treatment. Tumor thickness was measured from magnetic resonance (MR) images or computed tomography (CT) scans. The overall survival rates of patients with or without PND were 94 and 81 %, respectively (p = 0.2857). MR images or CT scans were available for 68 patients. A tumor thickness aeyen10 mm or aeyen5 mm did not increase the probability of nodal metastasis, with late nodal metastasis observed in 15 % of patients with graphically undetected small tumors. PND appears to have the potential to improve overall survival for patients with cN0 tongue SCC. Careful follow-up management or PND is considered to be needed regardless of tumor thickness in the pre-treatment evaluation.

  英語, 研究論文（学術雑誌）, Objective
  To determine the relationship between tumor glucose metabolism and tumor blood flow (TBF) in head and neck squamous cell carcinoma (HNSCC).
  Methods
  We retrospectively analyzed 57 HNSCC patients. Tumor glucose metabolism was assessed by maximum and mean standardized uptake values (SUVmax and SUVmean) obtained by 18 F-fluorodeoxyglucose positron-emission tomography. TBF values were obtained by arterial spin labeling with 3-tesla MRI. The correlations between both SUVs and TBF were assessed in the total series and among patients divided by T-stage (T1-T3 and T4 groups) and tumor location (pharynx/oral cavity and sinonasal cavity groups). Pearson's correlation coefficients were calculated for significant correlations.
  Results
  Significant correlations were detected: a negative correlation in the advanced T-stage group (TBF and SUV max: r, -0.61, SUVmean: r, -0.62), a positive correlation in the non-advanced T-stage pharynx/oral cavity group (TBF and SUVmax: r, 0.70, SUVmean: r, 0.73), a negative correlation in the advanced T-stage pharynx/oral cavity group (TBF and SUVmax: r, -0.62, SUVmean: r, -0.65), and a negative correlation in the advanced Tstage sinonasal cavity group (TBF and SUVmax: r, -0.61, SUVmean: r, -0.65).
  Conclusion
  Significant correlations between glucose uptake and TBF in HNSCC were revealed by the division of T-stage and tumor location.

  英語, 研究論文（学術雑誌）, We sought to evaluate the efficacy and feasibility of superselective intra-arterial infusion of high-dose cisplatin with concomitant radiotherapy (hereafter RADPLAT) for head and neck squamous cell cancer (hereafter HNSCC) patients with retropharyngeal lymph node (hereafter RPLN) metastasis. A retrospective case series review was conducted at University medical center in Japan. Ten HNSCC patients with RPLN metastasis treated by RADPLAT were analyzed. The ascending pharyngeal artery was targeted for the treatment of RPLN metastasis in 9 patients. The median total dose of cisplatin was 26.6 mg/m(2) (mean 31.5 mg/m(2), range 11.7-87.9 mg/m(2)). In the remaining patient, the RPLN was supplied by the ascending palatine artery. As grade 3 and 4 adverse effects, leukopenia was observed in three, mucositis in four and nausea in one patient. No neurological complications were observed in any patients. Metastatic RPLNs were evaluated as a complete response in all patients. There was no recurrence of RPLN metastasis in any patients. Four patients remain alive without any evidence of disease and six patients died of disease. The 5-year overall survival rate was 50 %. We have shown that superselective intra-arterial cisplatin infusion for RPLNs was a feasible and effective approach for HNSCC patients with RPLN metastasis.

  英語, 研究論文（学術雑誌）, Background. Renal function influences decisions regarding treatment for patients with oropharyngeal squamous cell carcinoma (SCC). However, the importance of renal function in oropharyngeal SCC has not yet been reported.
  Methods. Four hundred sixty patients with oropharyngeal SCC treated with curative intent between April 2005 and March 2007 in 12 institutions in Japan were analyzed retrospectively.
  Results. Four hundred three patients (87.6%) showed a creatinine clearance (CrCl) >= 50 mL/min and 57 (12.4%) with a CrCl < 50 mL/min. Age was associated with worse overall survival (OS), whereas stage IVB, radiotherapy (RT), and CrCl < 50 were associated with worse OS on univariate analyses. Surgery and hypertension were associated with better OS on univariate analyses. On multivariate analysis, age, stage, hypertension, and CrCl were also found to be significantly associated with OS.
  Conclusion. Based on this retrospective study, impaired renal function is an independent predictor of increased risk of death in patients with oropharyngeal SCC. (C) 2016 Wiley Periodicals, Inc.

  英語, 研究論文（学術雑誌）, Objective: We aimed to evaluate the prognostic factors and efficacy of treatment modalities for patients with temporal bone cancer, and to determine if definitive chemoradiotherapy (CRT) for advanced-stage disease can provide a substitute for highly invasive surgeries.
  Study Design: Retrospective case series.
  Setting: Tertiary referral center.
  Patients: Sixty-six patients with previously untreated squamous cell carcinoma of the temporal bone treated with curative intent between April 1997 and March 2015.
  Intervention: Surgery alone, radiotherapy (RT) alone, surgery followed by RT or definitive CRT.
  Main Outcome Measure: The overall survival (OS) rate.
  Results: The 5-year OS rate for each T classification was 100% for T1, 76.2% for T2, 55.6% for T3, and 36.7% for T4. Univariable and multivariable analysis showed that T classification was an independent predictor of the OS rate (hazard ratio 5.66; 95% confidence interval 1.51-27.0; p = 0.015). Analysis by treatment modality revealed that the 5-year OS rate for patients with T1-2 was 100% for surgery and 81.3% for RT alone. The rate for patients with T3-4 was 52.1% for definitive CRT and 55.6% for surgery followed by RT with or without chemotherapy.
  Conclusions: Patients with T1-2 benefited from surgical intervention without significant morbidity or mortality. Our findings also suggested that definitive CRT might be appropriate as the first-line treatment for T3-4, especially in cases with unresectable tumors.

  Late toxicity after concurrent chemoradiotherapy (CCRT), such as dysphagia, in patients with squamous cell carcinoma of the head and neck has received a good deal of attention recently. The gastrostomy tube (G-tube) dependence rate 1 year after CCRT was reported to be 16.7-42.9% in Western countries. We evaluated swallowing outcomes after CCRT in patients with hypopharyngeal cancer (HPC) treated in our hospital and compared them with previous reports.

  We reviewed 96 consecutive patients with a HPC treated by radiotherapy with intravenous or intra-arterial chemotherapy between 2006 and 2013 at Hokkaido University Hospital, Sapporo, Japan.
  Results
  At 1 month after CCRT, 13 patients (13.7%) used a G-tube, whereas 5/91 (5.5%) and 4/81 (4.9%) used a G-tube at 3 and 6 months, respectively. Two patients used a G-tube at 12 and 24 months after CCRT (G-tube use rate: 2.8% at 12 months, and 3.2% at 24 months). The variables female, posterior wall primary, stage IV, ECOG performance status of 2, and smoking status were significantly associated with G-tube use at 12 months after CCRT, whereas the route of cisplatin administration was not related to G-tube use (p = 0.303).
  Conclusions
  The G-tube use rate up to 1year could be lower in Japanese patients than in Western patients according to previous reports. In particular, Japanese patients resume oral intake sooner than Western patients. Further study of the incidence of dysphagia after CCRT by ethnicity is required to clarify the differences in dysphagia after CCRT.

  英語, 研究論文（学術雑誌）, Background: Detecting superficial head and neck squamous cell carcinoma (HNSCC) by endoscopy is challenging because of limited morphological hallmarks, and iodine cannot be applied to head and neck lesions due to severe mucosal irritation. Upsilon-glutamyltranspeptidase (GGT), a cell surface enzyme, is overexpressed in several cancers, and it has been reported that Upsilon-glutamyl hydroxymethyl rhodamine green (gGlu-HMRG), a fluorescent targeting agent which can be enzymatically activated and becomes fluorescent after cleavage of a GGT-specific sequence, can be activated within a few minutes after application to animal models. We investigated whether early HNSCC can be detected by applying gGlu-HMRG to clinical samples.
  Methods: gGlu-HMRG was applied to four HNSCC cell lines, and fluorescence was observed by fluorescence microscopy and flow cytometry. Immunohistological examination was performed in three recent cases of endoscopic submucosal dissection (ESD) to investigate GGT expression. Fluorescence imaging with gGlu-HMRG in eight clinical samples resected by ESD or surgery was performed, and fluorescence intensity of tumor and normal mucosa regions of interest (ROI) was prospectively measured.
  Results: All four gGlu-HMRG-applied cell lines emitted green fluorescence. Immunohistological examination demonstrated that GGT was highly expressed in HNSCC of the recent three ESD cases but barely in the normal mucosa. Fluorescence imaging showed that iodine-voiding lesions became fluorescent within a few minutes after application of gGlu-HMRG in all eight resected tumors. Tumor ROI fluorescence intensity was significantly higher than in the normal mucosa five minutes after gGlu-HMRG application.
  Conclusions: Fluorescence imaging with gGlu-HMRG would be useful for early detection of HNSCC.

  英語, 研究論文（学術雑誌）, Background. The purpose of this study was to compare the hearing outcomes after surgery with reconstruction of the external auditory canal in combination with tympanoplasty, radiotherapy (RT) alone, and surgery followed by postoperative RT for T1 to 2N0M0 external auditory canal cancer.
  Methods. We performed a retrospective, single-institution review of consecutive patients with early-stage external auditory canal cancer treated with surgery and/or RT between April 1997 and August 2013. Audiological data included the pretreatment hearing thresholds and those obtained at 12 months after the completion of therapy.
  Results. When we compared the functional gains for air-conduction pure-tone average thresholds and mean air-bone gaps, those in the surgery group (n = 10) were significantly higher than those in the RT (n = 13) and surgery 1 RT (n = 5) groups.
  Conclusion. Adequate techniques for reconstruction of the external auditory canal in combination with tympanoplasty after complete surgical resection is useful for hearing preservation in addition to good survival outcomes. (c) 2015 Wiley Periodicals, Inc.

  英語, 研究論文（学術雑誌）, Purpose We evaluated the sonographic findings of immunoglobulin G4-related sclerosing sialadenitis (IgG4-SS).
  Methods Nineteen patients with IgG4-SS and 12 healthy volunteers (controls) were enrolled. The following sonographic features were evaluated: (1) enlargement of the submandibular gland by measurement of the longitudinal diameter and thickness; (2) the contour texture of the submandibular gland (smooth or rough); (3) the internal echo texture, categorized into three sonographic patterns (homogeneous, multiple hypoechoic nodule, and diffuse hypoechoic); and (4) quantitative color Doppler signaling.
  Results The longitudinal diameter and the thickness (mean +/- A SD) of the submandibular gland were significantly greater in patients than in controls (p = 0.005 and p < 0.001, respectively). Contour roughness was seen in 62.9 and 8.3 % of patients and controls (p < 0.001), respectively. Homogeneous echo textures alone were seen in controls, whereas multiple hypoechoic nodule patterns were seen in 60 % of the patients, and diffuse hypoechoic patterns were seen in 40 %. Color Doppler signaling (mean +/- A SD) was significantly higher in patients as compared with controls (p < 0.001).
  Conclusion Patients could be distinguished from healthy volunteers using four distinctive sonographic findings, suggesting that ultrasonography would be a useful diagnostic tool for IgG4-SS.

  英語, 研究論文（学術雑誌）, Background and Purpose: For the assessment of the treatment response in non-surgical treatment, tumor blood flow provides the functional information of the tumor which is different from the morphological information such as tumor volume. The purpose of this study was to evaluate the diagnostic value of tumor blood flow values obtained by pseudocontinuous arterial spin-labeling in patients with head and neck squamous cell carcinoma. Materials and Methods: Forty-one patients with head and neck squamous cell carcinoma were evaluated by using pseudocontinuous arterial spin-labeling. Quantitative tumor blood flow was calculated at the pretreatment and the early treatment periods in all the patients, and the percentage change of tumor blood flow between the two was calculated. At the early treatment period, based on their tumor volume reduction rate, we divided the patients into stable disease and partial response groups for a subgroup analysis. The local control or failure was confirmed either by histopathology or by radiologic evaluation within the follow-up. RESULTS: Pretreatment tumor blood flow in patients in the failure group was significantly lower than that in patients in the local control group. In the subgroup analysis of patients with stable disease, the percentage change of tumor blood flow was significantly larger (due to the tumor blood flow increase from pretreatment value) in the local control group than in the failure group. In addition, in patients with a partial response, the percentage change of tumor blood flow was significantly smaller (due to the tumor blood flow decrease from the pretreatment value) in the local control group than in the failure group. The accuracy for determination of the local control group or the failure group in pretreatment tumor blood flow was 0.83 and that in the combination use of the percentage change of tumor blood flow and tumor volume in the early treatment period was 0.93. Conclusions: Tumor blood flow obtained by pseudocontinuous ar terial spin-labeling can be useful for the determination of local control. The combined use of the percentage change of tumor blood flow and tumor volume had particularly high diagnostic accuracy.

  英語, Intra-arterial chemotherapy has been used to treat localized malignant neoplasms in patients with head and neck cancer for over 50 years as the head and neck region is particularly well suited to regional chemotherapy. Early intra-arterial chemotherapy did not prove its efficacy. In addition, the additional complications associated with establishing and maintaining arterial access have further dampened enthusiasm for this approach. Subsequent significant advances in vascular radiology techniques and the development of new devices, such as fluoroscopy units and angiographic catheters, have made possible safe, accurate and repeated superselective intra-arterial chemotherapy. Intra-arterial infusion of high-dose cisplatin with systemic neutralization by intravenous sodium thiosulfate (RADPLAT) is a theoretically attractive approach to the treatment of advanced head and neck cancer. However, a Dutch trial comparing intra-arterial and intravenous chemoradiotherapy for advanced head and neck cancer showed that RADPLAT was not superior to intravenous chemoradiotherapy. Therefore, further investigation of RADPLAT, including the refinement of the indications for its application, is needed.

  英語, 研究論文（学術雑誌）, Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic autoimmune disease that manifests as asthma, recurrent sinusitis and peripheral eosinophilia. In this study, we investigated the clinical features of the ear and nasal manifestations of EGPA in comparison with those of granulomatosis with polyangiitis (GPA). Materials and Methods: Twenty-one patients diagnosed with EGPA were studied. The frequency of otologic manifestations, the degree of hearing loss and the frequency of nasal symptoms were assessed. The onset of ear symptoms, sinusitis and asthma in patients with EGPA were also examined. Results: Eleven patients (52.4%) with EGPA demonstrated otologic symptoms. The EGPA patients commonly presented mild-to-moderate mixed or sensorineural hearing loss. The pattern of hearing loss was mainly flat, and all but 1 patient achieved complete remission from their hearing impairments. Eighteen patients (85.7%) with EGPA demonstrated nasal symptoms. Patients with EGPA showed a significantly higher incidence of nasal polyps than did those with GPA. The median Lund and Mackey scoring system score was 13.7 for patients with EGPA, and ethmoid sinus shadows were more severe than those of the maxillary sinus. Most ear symptoms associated with EGPA were observed after definitive diagnosis, although sinusitis and asthma tended to manifest themselves before diagnosis. There were significant differences between the onset of ear symptoms and those of asthma and sinusitis. Conclusion: As over 80% of patients with EGPA had nasal symptoms and over half had ear symptoms, otolaryngologists should be aware of this disease. Recognition of the characteristic ear and nasal symptoms are thought to be particularly important to obtain an early diagnosis of EGPA. (C) 2016 S. Karger AG, Basel

  英語, 研究論文（学術雑誌）, Objectives: To evaluate the hearing outcomes of intratympanic steroid (ITS) treatment for patients with acute low-tone sensorineural hearing loss (ALHL) after failure of initial therapy and to investigate the recurrence and progression to definite Meniere's disease (MD) during a long-term follow-up. Methods: We retrospectively reviewed the medical records of 90 patients with refractory ALHL who were followed up for at least 1 year between January 2000 and April 2014. Patients who responded poorly to initial medical treatment received intratympanic dexamethasone injections (ITS group) or isosorbide administration for 4 weeks (diuretic group) as salvage treatment options according to their choice of management. The control group did not receive ITS or the diuretic, due to their refusal of both medical treatments. The hearing outcomes were evaluated 1 month, 1 year and 5 years after the completion of the second-line therapy, and the rates of recurrence and progression to MD were measured during a follow-up period of at least 1 year. Results: Twenty-seven patients in the ITS group, 39 patients in the diuretic group and 24 patients in the control group were enrolled. Of these, 12 patients in the ITS group, 15 patients in the diuretic group and 12 patients in the control group were followed up for over 5 years. We found that the recovery rates and the audiometric functional values after 1 month and 1 year in the ITS group were significantly higher than those in the diuretic and control groups. However, there were no significant differences in the recovery rates or the audiometric functional values after 5 years, or in the rates of recurrence and progression to MD between the groups. Conclusions: Salvage ITS therapy can provide a relatively good short-term hearing outcome for ALHL patients who have persistent hearing loss despite conventional treatment. However, both recurrence and progression to MD after treatment were observed in some patients during the long-term follow-up. (C) 2016 S. Karger AG, Basel

  英語, 研究論文（学術雑誌）, Background Pyriform sinus squamous cell carcinoma (SCC) has one of the worst prognoses of all upper aerodigestive tract cancers. Improving clinical outcomes for patients with hypopharyngeal SCC has been particularly challenging for head and neck surgeons and oncologists.
  Methods We investigated 30 patients with pyriform sinus SCC to verify the effectiveness of weekly cisplatin chemotherapy with concurrent radiotherapy. Cisplatin was administered at a dose of 40 mg/m(2) on weeks 1, 2, 3, 5, 6, and 7 during definitive radiotherapy with the aim of preserving the larynx.
  Results All 30 patients achieved definitive radiotherapy at a median dose of 70 Gy (range 64-70 Gy). Cisplatin was administrated concomitantly a median of five times (range 2-6 times). Persistent or recurrent primary disease was observed in four patients (13 %). Persistent or recurrent nodal metastasis was observed in five patients (17 %). Nine salvage surgeries were performed for eight patients, of whom seven survived without any evidence of disease. Post-operative complications were observed in two patients (22 %). The 5-year overall survival and locoregional control rates were 87 and 96 %, respectively. The 5-year laryngeal preservation rate was 74 %.
  Conclusions The regimen of weekly cisplatin CRT may be effective for pyriform sinus SCC; however, there were problems with strong selection bias in the current study due to the large number of T2 patients. Salvage surgery was safe and was able to improve the survival rate. This chemoradiation regimen was considered successful in preserving laryngeal function.

  英語, 研究論文（学術雑誌）, Objective: We retrospectively assessed the indications for superselective intra-arterial infusion of cisplatin with concomitant radiotherapy (RADPLAT) in patients with hypopharyngeal cancer (HPC).
  Methods: Between April 2000 and March 2013,41 previously untreated patients received superselective intra-arterial infusion of cisplatin (100-120 mg/m(2) per week) with simultaneous intravenous infusions of thiosulfate to neutralize cisplatin toxicity and conventional radiotherapy (65-70 Gy).
  Results: During the median follow-up period of 5.5 years, a statistically significant difference in the 5-year overall survival was noted between patients with N0-1 (n = 14) and N2b-3 disease (n = 27). One-half of deaths were observed to be the result of distant metastasis. The 5-year local control and overall survival were significantly better in patients with unilateral than in those with bilateral primary tumors. All the patients with T4b disease (n = 3) died of disease within 2 years.
  Conclusion: Indications for RADPLAT in patients with HPC were defined as patients with unilateral tumors staged as T3-4a and N0-1. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, Total laryngo-pharyngo-esophagectomy (TLPE) with gastric pull-up reconstruction is still considered to be associated with major complications and a significant risk of in-hospital death. Minimally invasive esophagectomy, avoiding thoracotomy and laparotomy, has been increasingly performed for esophageal malignancies with the hope of reducing mortality and morbidity, such as pulmonary complications. The aim in this study was to assess early and long-term morbidity as well as treatment outcomes in patients treated with TLPE with gastric pull-up reconstruction via thoracoscopy, laparoscopy and cervical incision. From 2004 to 2013, 10 patients with a median age of 64 years (range 47-71 years) underwent minimally invasive TPLE with gastric pull-up reconstruction. Seven of the 10 patients had previously received radiotherapy. As for early postoperative complications, no patient died during the early postoperative period, and pneumonia was observed in 1, skin necrosis in 1, pseudomembranous enterocolitis in 1, arrhythmia in 2, hemorrhage in the neck in 2, anastomotic leakage in the neck in 3, and tracheal necrosis in 6 patients. Three patients developed tracheostomal stenosis as a long-term postoperative complication, and an anastomotic stricture was observed in one patient. All patients were able to achieve oral intake, but 3 patients required feeding tube support. In conclusion, postoperative systemic complications during the early postoperative period were considered to be acceptable, although wound complications such as tracheal necrosis and anastomotic leakage were commonly observed. Therefore, this minimally invasive procedure might help reduce mortality and morbidity in patients requiring TLPE with gastric pull-up reconstruction.

  英語, 研究論文（学術雑誌）, Objectives: To investigate the diagnostic value of tumor blood flow (TBF) obtained with pseudocontinuous arterial spin labeling (pCASL) for the differentiation of squamous cell carcinoma (SCC) and malignant lymphoma (ML) in the nasal or sinonasal cavity.
  Methods: Thirty-three patients with SCC and 6 patients with ML in the nasal or sinonasal cavity were retrospectively analyzed. Quantitative TBF values were obtained using whole-tumor region of interest (ROI) from pCASL data. The histogram analysis of TBF values within the tumor ROI was also performed by calculating the coefficient of variation (CV), kurtosis, and skewness. The mean TBF value, histogram CV, kurtosis and skewness of the patients with SCC were compared with those of the ML patients. The diagnostic accuracy to differentiate SCC from ML was also calculated by receiver operating characteristic (ROC) curve analysis. In addition, multiple logistic regression models were also performed to determine their independent predictive value, and diagnostic accuracy with the combined use of these parameters.
  Results: Between the SCC and ML groups, significant differences were observed in mean TBF, CV, and kurtosis, but not in skewness. In ROC curve analysis, the diagnostic accuracy values for the differentiation of SCC from ML in mean TBF, CV, and kurtosis were all 0.87, respectively. Multiple logistic regression models revealed TBF and CV were respectively independent predictive value. With the combination of these parameters, the diagnostic accuracy was elevated to 0.97.
  Conclusions: The TBF value and its histogram analysis obtained with pCASL can help differentiate SCC and ML. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, Objective: Here we report our experience of patients with squamous cell carcinoma (SCC) of the nasal cavity and ethmoid sinus (NC&ES) together with an analysis of treatment outcomes.
  Methods: A retrospective analysis was performed using data from 25 consecutive patients treated between 2000 and 2012. Four patients were diagnosed with T1, 3 with T2, 4 with T3, 7 with T4a, and 7 with T4b disease. No patient had lymph node metastasis.
  Results: Twelve patients were treated with surgery with/without radiotherapy and with/without chemotherapy. Of these, 4 underwent endoscopic surgery without an open approach and 3 required an anterior skull base approach. Thirteen were treated with radiotherapy; 1 with radiotherapy alone, and 4 and 8 with intravenous and intra-arterial chemotherapy, respectively. The 5-yr overall survival for T1-3, T4a, and T4b disease was 53.9%, 71.4%, and 29.0%, respectively. The 5-yr disease-specific survival for T1-3, T4a, and T4b disease was 74.1%, 71.4%, and 29.0%, respectively.
  Conclusion: Our treatment policy for patients with SCC of NC&ES, which basically follows the NCCN guideline, was considered to be appropriate. However, several points in terms of surgery and nonsurgical approach remain to be solved through further research. (C) 2015 Elsevier Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, Conclusion: Grade >= 3 mucositis/stomatitis and inability to feed orally were problematic for patients undergoing cetuximab-based bioradiotherapy (BRT) as well as platinum-based chemoradiotherapy (CRT). Severe mucositis/stomatitis and radiation dermatitis should be addressed carefully in patients undergoing cetuximab-based BRT as well. Objectives: The efficacy of cetuximab-based BRT in locally advanced head and neck squamous cell carcinomas has been established. However, the safety of cetuximab-based BRT in comparison with platinum-based CRT is currently under investigation. Method: This study retrospectively analyzed 14 patients undergoing cetuximab-based BRT and 29 patients undergoing platinum-based CRT to compare the incidence of acute toxicities. In the BRT group, an initial cetuximab loading dose of 400 mg/m(2) was delivered 1 week before the start of radiotherapy. Seven weekly infusions of 250 mg/m(2) of cetuximab followed during the definitive radiotherapy. In the CRT group, cisplatin was administered at a dose of 40 mg/m(2) weekly during the definitive radiotherapy. Results: The BRT group had a higher incidence of Grade >= 3 radiation dermatitis than did the CRT group (43% vs 3%, respectively, p < 0.01). The incidence rate of Grade >= 3 mucositis/stomatitis was 64.3% and 41.4% in the BRT and CRT group, respectively (p = 0.1484), while the incidence rate of the inability to feed orally was 38.5% and 55.2%, respectively (p = 0.2053).

  英語, 研究論文（学術雑誌）, We conducted a phase II study to evaluate the efficacy and safety of chemoradiotherapy concurrent with S-1 plus cisplatin in patients with unresectable locally advanced squamous cell carcinoma of the head and neck. Chemotherapy consisted of S-1 twice daily on days 1-14 at 60 mg/m(2) /day and cisplatin at 20 mg/m(2) /day on days 8-11, repeated twice at a 5-week interval. Single daily radiation of 70 Gy in 35 fractions was given concurrently starting on day 1. For patients achieving an objective response after chemoradiotherapy, two additional cycles of chemotherapy were administered. Of the 45 enrolled patients, the percentage of clinical complete remission, the primary endpoint, was 64.4% (8 complete response, 21 good partial response) on central review. After a median follow-up of 3.52 years, 3-year local progression-free survival was 62.2%, with 3-year progression-free survival of 60.0%, 3-year overall survival of 64.4%, and 3-year time to treatment failure of 48.9%. Grade 3 or 4 toxicity included pharyngeal mucositis (46.7%), oral mucositis (44.4%), dysphagia (46.7%), anorexia (42.2%), radiation dermatitis (26.7%), neutropenia (26.7%), and febrile neutropenia (4.4%). No treatment-related deaths were observed. This combination showed promising efficacy with acceptable toxicities.

  英語, 研究論文（学術雑誌）, The aim of this study was to evaluate the feasibility of induction docetaxel, cisplatin, and 5-fluorouracil chemotherapy followed by concurrent weekly cisplatin chemoradiotherapy for patients with locally advanced head and neck squamous cell carcinoma (HNSCC).
  Between 2010 and 2013, 30 patients with Stage IV HNSCC were treated in Hokkaido University Hospital with three cycles of induction chemotherapy (docetaxel 75 mg/m(2) and cisplatin 75 mg/m(2), day 1; and 5-fluorouracil 750 mg/m(2)/day 120 h continuous infusion, every 3 weeks) followed by concurrent weekly cisplatin (40 mg/m(2), on weeks 1, 2, 3, 5, 6 and 7) chemoradiotherapy.
  Three courses of induction chemotherapy were performed in 25 patients (83 %) with grade 3-4 toxicities during induction chemotherapy observed in 22 patients (73 %). The major toxicities were hematologic, with 22 cases (73 %) showing grade 3-4 neutropenia. Radiotherapy was completed (70 Gy) in 29 patients (97 %), while a total of 19 patients (63 %) completed five (13 patients) or six (6 patients) courses of chemotherapy. During concurrent chemoradiotherapy, no grade 4 hematological toxicities were observed. Grade 4 dermatitis was observed in one patient, and grade 3 mucositis was observed in 12 patients. There were no treatment-related deaths during the induction chemotherapy or concurrent chemoradiotherapy. The 1- and 2-year progression-free survival rates and the 1- and 2-year overall survival rates were 86 %, 72 %, and 89 %, 81 %, respectively.
  Sequential therapy composed of induction chemotherapy followed by concurrent weekly cisplatin chemoradiotherapy is feasible, showing encouraging results in patients with locally advanced HNSCC. Concurrent weekly cisplatin chemoradiotherapy following induction chemotherapy appears to be a suitable alternative to three-weekly high-dose cisplatin therapy.

  英語, 研究論文（学術雑誌）, BackgroundThe purpose of this retrospective analysis was to evaluate ocular function and survival rates among treatment modalities in patients with maxillary sinus cancer with orbital invasion.
  MethodsEighty-seven patients were classified according to the main treatment modality. Ocular function preservation rates and survival rates were evaluated for each therapeutic modality.
  ResultsThe 5-year overall survival rate for the en bloc resection, conservative surgery, superselective intra-arterial chemotherapy, and radiotherapy (RADPLAT), intravenous chemoradiotherapy (IV-CRT) was 70%, 35%, 49%, and 31%, respectively. The ocular function preservation rate for each group was 15%, 27%, 30%, and 17%, respectively. In the en bloc resection group, there was no significant difference in the 5-year overall survival rate between patients with orbital exenteration and those without orbital exenteration (72% vs 71%; p=.9321).
  ConclusionThe en bloc resection group showed a favorable survival rate but a low preservation rate. Preservation of orbital contents did not reduce the survival rate. (c) 2014 Wiley Periodicals, Inc. Head Neck37: 537-542, 2015

  英語, 研究論文（学術雑誌）, PurposeTo investigate the feasibility of tumor blood flow (TBF) measurement in head and neck squamous cell carcinoma (HNSCC) using pseudo-continuous arterial spin labeling (pCASL) in a comparison with dynamic contrast-enhanced (DCE) perfusion.
  Materials and MethodsWe prospectively scanned 18 patients with HNSCC using 3T magnetic resonance imaging (MRI) with both pCASL and DCE perfusion. Quantitative TBF value in the whole-tumor region of interest (ROI), and regional TBF in the ROIs of the central and peripheral areas in the tumor were respectively measured. Relative TBF value in the whole-tumor ROI was also calculated. We determined the correlation and agreement between each measured TBF by pCASL and DCE perfusion using Pearson's correlation coefficients, intraclass correlation coefficients (ICC), and Bland-Altman analysis.
  ResultsIn the whole-tumor ROIs, significant correlation was observed between the absolute TBF values (r=0.72, P<0.01), with an ICC of 0.72; moreover, higher correlation was observed in the relative TBF (r=0.79). The correlation was higher in the peripheral ROI (r=0.70) than the central ROI (r=0.65), with an ICC of 0.62 and 0.54, respectively. Bland-Altman plots revealed the underestimation of TBF by pCASL in central ROIs.
  ConclusionTBF measurement by pCASL was feasible in patients with HNSCC. J. Magn. Reson. Imaging 2015;41:983-991. (c) 2014 Wiley Periodicals, Inc.

  英語, 研究論文（学術雑誌）, Background: Olfactory neuroblastoma (ONB) is a rare tumor originating from olfactory epithelium. Here we retrospectively analyzed the long-term treatment outcomes and toxicity of radiotherapy for ONB patients for whom computed tomography (CT) and three-dimensional treatment planning was conducted to reappraise the role of radiotherapy in the light of recent advanced technology and chemotherapy.
  Methods: Seventeen patients with ONB treated between July 1992 and June 2013 were included. Three patients were Kadish stage B and 14 were stage C. All patients were treated with radiotherapy with or without surgery or chemotherapy. The radiation dose was distributed from 50 Gy to 66 Gy except for one patient who received 40 Gy preoperatively.
  Results: The median follow-up time was 95 months (range 8-173 months). The 5-year overall survival (OS) and relapse-free survival (RFS) rates were estimated at 88% and 74%, respectively. Five patients with stage C disease had recurrence with the median time to recurrence of 59 months (range 7-115 months). Late adverse events equal to or above Grade 2 in CTCAE v4.03 were observed in three patients.
  Conclusion: Multimodal therapy including radiotherapy with precise treatment planning based on CT simulation achieved an excellent local control rate with acceptable toxicity and reasonable overall survival for patients with ONB.

  英語, The suprasternal space is a narrow space between the superficial and deep layers of the investing layers of the deep cervical fascia above the manubrium of the sternum. The suprasternal space has been paid littleattention as a space with the potential for lymph nodemetastasis from both thyroid cancer and head and neckcancer. We experienced 2 patients who were found to have a lymph node in the suprasternal space preoperatively. Both of them had well-differentiated thyroid papillary carcinomas and level III and IV lymph node metastases as well as metastasis in the suprasternal space. We have not previously dissected the suprasternal space prophylactically in other patients with thyroid papillary cancer, but no patient has developed metastasis in this space to date. Thesuprasternal space is not usually dissected in atients with thyroid cancer. However, suprasternal space metastasis has been reported to occur occasionally in patients with lymph node metastases in levels III and IV. We consider that dissection of the suprasternal space, which is not routinely performed, should be done when preoperative examination suggests lymph node metastasis in the suprasternal space as dissection of this space is less invasive, easy to achieve, and is not time consuming. Greater attention should be paidto the suprasternal space as an area with the otential for lymph node metastasis from thyroid cancer.

  英語, 研究論文（学術雑誌）, Objectives: To investigate the diagnostic value of tumour blood flow (TBF) obtained with pseudocontinuous arterial spin labelling for the differentiation of squamous cell carcinoma (SCC) and inverted papilloma (IP) in the nasal or sinonasal cavity. Methods: We retrospectively analysed the cases of 33 patients with SCC and 8 patients with IP in the nasal or sinonasal cavity. Pseudocontinuous arterial spin labelling scanning was performed for all patients using a 3.0-T MR unit. Quantitative TBF values were measured by two neuroradiologists by respectively delineating the whole-tumour regions of interest, and the mean of them was determined as TBF value in each patient. Additionally, the presence of imaging findings of convoluted cerebriform pattern (CCP) on MR T 2 weighted images was determined in all patients. As a subgroup analysis, patients with IP were divided into aggressive and non-aggressive IPs depending on their progression range. First, an intraclass correlation coefficient (ICC) of TBF values between two neuroradiologists was determined. Next, a statistical comparison of the TBF value by a Mann-Whitney U test between the patients with SCC and IP was performed. Additionally, the comparison by an ANOVA with a post hoc test of Tukey's method among the SCC, non-aggressive IP and aggressive IP groups was also performed. If significance was observed, the diagnostic accuracy to differentiate SCCs from IPs was calculated. Diagnostic accuracy by CCP findings alone and by the combination of CCP findings and TBF were also assessed. Results: The ICC of TBF values between two neuroradiologists was 0.82. The mean TBF values in the patients with SCC, all patients with IP, those with aggressive IP and those with non-aggressive IP were 141.2 ± 33.1, 77.8 ± 31.5, 109.4 ± 16.7 and 58.8 ± 19.9ml 100 g -1 min -1 , respectively. A significant difference was observed between SCC and IP (p,0.001), SCC and non-aggressive IP (p < 0.01) and non-aggressive IP and aggressive IP (p < 0.01). The diagnostic accuracy values obtained with receiver operating characteristic curve analysis for the differentiation of SCC from IP and for SCC from non-aggressive IP were 0.90 and 0.92, respectively. The diagnostic accuracy was elevated (0.95 from 0.88) by adding the TBF value to CCP findings. Conclusions: The pseudocontinuous arterial spin labelling technique can be a useful noninvasive diagnostic tool to differentiate SCC from IP in nasal or sinonasal cavity.

  英語, 研究論文（学術雑誌）, A dose-finding and efficacy confirmation trial was started in Japan in April 2014 to evaluate the efficacy and safety of superselective intra-arterial infusion of cisplatin and concomitant radiotherapy for locally advanced maxillary sinus cancer. A total of 18 patients will be enrolled in the dose-finding phase for the determination of the recommended number of cisplatin cycles, and 65 patients with T4aN0M0 and 62 patients with T4bN0M0, including those who received the recommended number of or fewer cycles in the dose-finding phase, will be enrolled from 16 institutions within a 5-year period in the efficacy confirmation phase. The primary endpoints of the dose-finding and the efficacy confirmation phases are dose-limiting toxicities and 3-year overall survival, respectively. This trial was registered at the UMIN Clinical Trials Registry (http://www.umin.ac.jp/ctr/) under Trial No. UMIN000013706.

  英語, 研究論文（学術雑誌）, Objective Many proinflammatory cytokines are regulated by the acetylation and deacetylation of the core histone. Since dysregulation of T helper 2 cytokine production is a key in the pathogenesis of allergic diseases, we examined the role of histone deacetylase (HDAC) on interleukin (IL)-4 gene expression in mast cells. We also examined whether oxidative stress has any impact on HDAC activity.
  Study Design In vitro study.
  Setting Academic research laboratory.
  Methods An IgE-sensitized mast cell line (RBL-2H3 cells) was treated with varying concentrations of the HDAC inhibitors trichostatin A (TSA) and H2O2 and stimulated with antigens. The amount of IL-4 gene expression was quantified by real-time polymerase chain reaction. Quantitative measurement of IL-4 in the cell supernatant was performed using enzyme-linked immunosorbent assay. Moreover, HDAC activity was measured with the use of a nonisotopic assay that utilized an HDAC Fluorescent Activity Assay Kit.
  Results IL-4 mRNA expression was induced by antigens in IgE-sensitized RBL-2H3 cells. Pretreatment with TSA and H2O2 enhanced IL-4 mRNA expression up to 5-fold in a dose-dependent manner. Furthermore, HDAC activity in RBL-2H3 cells was reduced after treatment with H2O2.
  Conclusion Our results suggest that oxidative stress may up-regulate IL-4 gene expression in mast cells via a decrease in HDAC activity.

  英語, 研究論文（学術雑誌）, Purpose: Severe oral and pharyngeal mucositis is one of the most critical toxicities known to lead to the discontinuation of chemoradiotherapy (CRT) for head and neck cancer (HNC). Hangeshashinto (TJ-14) is a Kampo medicine that relieves chemotherapy-induced oral mucositis. We. investigated the effect of TJ-14 on mucositis, nutritional status, and the completion rate of CRT. Methods: The study group comprised patients with advanced HNC who were treated with concomitant weekly cisplatin and 70 Gy of radiotherapy. The primary endpoint was the completion rate of chemotherapy, and the secondary endpoints were the grade of mucositis and the nutritional status. Results: A total of 57 patients were included in this study. The completion rate of CRT among patients who were treated with TJ-14 was 91.4%. There was a significant difference in the completion rate of CRT between the groups treated with and without TJ-14 (p = 0.0452). The reduction in body weight was significantly improved from 10.89 to 5.89% with TJ-14 administration (p = 0.003), and the reduction in serum albumin was also significantly decreased from 17.37 to 8.73%. (p = 0.024). Conclusion: This therapy allowed a high completion rate of CRT as well as significant benefits in terms of nutritional status. We plan to carry out a further large-scale study of TJ-14.

  英語, 研究論文（学術雑誌）, Conclusions: Superselective intra-arterial cisplatin infusion with concomitant radiotherapy (RADPLAT) is considered to be one of the treatments of choice for patients with adenoid cystic carcinoma (ACC) who prefer not to undergo radical surgery. Objective: To evaluate the efficacy of RADPLAT for patients with ACC of the head and neck. Patients and methods: Between 2001-2010, nine patients with untreated ACC were given superselective intra-arterial infusion of cisplatin (100-120 mg/m(2)/ week) with simultaneous intravenous infusion of thiosulfate to neutralize cisplatin toxicity and radiotherapy (65-70 Gy). Results: Five patients had tumors arising in the base of the tongue, two in the maxillary sinus, and the remaining two in the nasopharynx. The median follow-up period was 9 years 7 months (9; 7) (range = 4; 6-12; 5), and the 5-year local control (LC), overall survival (OS), and disease-free survival rates were 88.9%, 88.9%, and 55.6%, respectively. The 10-year OS rate was 57.1%, but all patients who remained alive for over 10 years are still alive with disease. Primary tumor recurrence was observed in five of the nine patients, with the median time to recurrence being 6 years (range = 4-9 years). Five of the nine patients had distant metastasis, and of these three patients also had primary recurrence.

  日本語, 研究論文（学術雑誌）, 中咽頭癌は頸部腫瘤が初発症状となることもあり、頸部腫瘤摘出・生検後の精査にて原発が判明する場合もある。今回われわれは頸部腫瘤摘出・生検後に中咽頭癌と診断された症例について検討を行った。対象は1998年1月から2013年12月までの16年間に頸部腫瘤摘出・生検後に中咽頭癌と診断された11例である。頸部腫瘤摘出・生検の経緯は、診断確定のためにリンパ節生検を行ったのが6例、側頸嚢胞の術前診断にて摘出術を行ったのが4例、原発不明癌として頸部郭清術を行ったのが1例であった。頸部腫瘤摘出・生検後に判明した原発巣は口蓋扁桃が6例、舌根が5例であった。口蓋扁桃原発例は6例中5例がヒト乳頭腫ウイルス(Human Papillomavirus;HPV)陽性で、舌根原発例は5例中3例がHPV陽性であった。頸部腫瘤摘出・生検から原発確定までの期間は1〜13ヵ月であった。全症例に対して最終的には放射線療法または化学放射線療法が施行されており、放射線治療後は現在まで再発や転移はなく経過している。近年HPV関連中咽頭癌が増加傾向にあり、頸部腫瘤を初発症状とする中咽頭癌症例は増加するものと思われる。頸部腫瘤の鑑別に当たっては中咽頭を十分に精査する必要があると思われた。また、HPV関連中咽頭癌は転移リンパ節が嚢胞性を呈することがあり、頸部嚢胞性病変の鑑別においては中咽頭癌の転移リンパ節も念頭に置く必要があると思われた。(著者抄録)

  英語, 研究論文（学術雑誌）, Purpose: To investigate the correlation between perfusion-related parameters obtained with intravoxel incoherent motion (IVIM) and classical perfusion parameters obtained with dynamic contrast-enhanced (DCE) magnetic resonance imaging in patients with head and neck squamous cell carcinoma (HNSCC), and to compare direct and asymptotic fitting, the pixel-by-pixel approach, and a region of interest (ROI)-based approach respectively for IVIM parameter calculation.
  Materials and methods: Seventeen patients with HNSCC were included in this retrospective study. All magnetic resonance (MR) scanning was performed using a 3 T MR unit. Acquisition of IVIM was performed using single-shot spin-echo echo-planar imaging with three orthogonal gradients with 12 b-values (0, 10, 20, 30, 50, 80, 100, 200, 400, 800, 1000, and 2000). Perfusion-related parameters of perfusion fraction 'f' and the pseudo-diffusion coefficient 'D*' were calculated from IVIM data by using least square fitting with the two fitting methods of direct and asymptotic fitting, respectively. DCE perfusion was performed in a total of 64 dynamic phases with a 3.2-s phase interval. The two-compartment exchange model was used for the quantification of tumor blood volume (TBV) and tumor blood flow (TBF). Each tumor was delineated with a polygonal ROI for the calculation of f, f center dot D* performed using both the pixel-by-pixel approach and the ROI-based approach. In the pixel-by-pixel approach, after fitting each pixel to obtain f, f center dot D* maps, the mean value in the delineated ROI on these maps was calculated. In the ROI-based approach, the mean value of signal intensity was calculated within the ROI for each b-value in IVIM images, and then fitting was performed using these values. Correlations between fin a total of four combinations (direct or asymptotic fitting and pixel-by-pixel or ROI-based approach) and TBV were respectively analyzed using Pearson's correlation coefficients. Correlations between f center dot D* and TBF were also similarly analyzed.
  Results: In all combinations of f and TBV, f center dot D* and TBF, there was a significant correlation. In the comparison of f and TBV, a moderate correlation was observed only between f obtained by direct fitting with the pixel-by-pixel approach, whereas a good correlation was observed in the comparisons using the other three combinations. In the comparison of f center dot D* and TBF, a good correlation was observed only with f center dot D* obtained by asymptotic fitting with the ROI-based approach. In contrast, moderate correlations were observed in the comparisons using the other three combinations.
  Conclusion: IVIM was found to be feasible for the analysis of perfusion-related parameters in patients with HNSCC. Especially, the combination of asymptotic fitting with the ROI-based approach was better correlated with DCE perfusion. (C) 2014 Elsevier Inc. All rights reserved.
• Epithelial-mesenchymal transition in human papillomavirus-positive and -negative oropharyngeal squamous cell carcinoma

  英語, 研究論文（学術雑誌）, High-risk human papillomavirus (HPV) infection is associated with carcinogenesis in oropharyngeal squamous cell carcinoma (OPSCC) and patients with HPV-positive tumors have a significantly favorable prognosis. However, the underlying mechanism of this favorable clinical outcome remains unclear. Epithelial-mesenchymal transition (EMT) causes aggressiveness of cancer cells and we investigated the expression of the EMT markers and analyzed their correlation with HPV status and prognosis in order to examine the treatment response of HPV-positive OPSCCs. A total of 79 patients with OPSCC were examined in the present study. All high-risk HPV infections were determined with the multiplex PCR kit from each formalin-fixed paraffin-embedded (FFPE) sample. We performed immunohistochemical staining for E-cadherin and vimentin. Expression of the markers was graded and we statistically analyzed the correlation between tumor, node, metastasis (TNM) stages and prognosis. High-risk HPV-positive tumors were detected in 23 cases. The five-year survival rate in HPV-positive and -negative tumors was 82.7 and 48.3%, respectively. High E-cadherin expression rate in HPV-negative samples was 76.7% and 43.4% in HPV-positive samples (p=0.007). Vimentin expression did not show a difference between HPV-positive and -negative tumors. HPV-negative patients presented significantly greater heterogeneity of E-cadherin expression compared to HPV-positive patients (p=0.0349). HPV-positive OPSCCs originally lost their epithelial cell phenotype compared with HPV-negative tumors. Therefore, the paradoxical favorable prognosis of HPV-positive OPSCC may be due to the intratumor homogeneity in EMT.

  日本語, 研究論文（学術雑誌）, In the case of oropharyngeal carcinoma, patients may present with symptoms similar to cervical lymphadenopathy, and the primary lesion may only be diagnosed after cervical mass extirpation/biopsy. We retrospectively analyzed the clinical course in 11 oropharyngeal carcinoma patients that were diagnosed after cervical mass extirpation/biopsy between 1998 and 2013. Before the diagnosis was made of oropharyngeal carcinoma, a cervical lymph node biopsy was performed in six patients
  the lymph node was extirpated due to an initial diagnosis of lateral cervical cyst in four patients
  and neck dissection was performed due to an initial diagnosis of primary unknown carcinoma in one patient. The primary tumor site in the oropharynx was the palatine tonsil in six patients and the lingual tonsil in five patients. Five of six patients with palatine tonsil carcinoma and three of five patients with lingual tonsil carcinoma were found to be positive for human papillomavirus (HPV). The duration from cervical lymph node extirpation/biopsy to final diagnosis was 1 to 13 months. All patients finally underwent radiation therapy or chemoradiotherapy, and they had no recurrence or metastasis. As the incidence of HPV-related oropharyngeal carcinoma increases, the number of oropharyngeal carcinomas assumed to be cervical lymphadenopathy due to the presenting symptoms may increase. It is important to investigate the oropharynx thoroughly so as to adequately differentiate the possibility of oropharyngeal carcinoma from that of cervical lymphadenopathy. Metastatic lymph nodes might present as cysts in cases of oropharyngeal carcinoma, it is therefore necessary to take the potential for metastatic lymph nodes in the oropharyngeal cancer into consideration when differentiating this disease from cervical cyst-shaped lesions.

  英語, 研究論文（学術雑誌）, BackgroundWe analyzed the effects of local extension sites on survival in patients with locally advanced maxillary sinus cancer.
  MethodsThe criteria for inclusion in this study were as follows: (1) previously untreated maxillary sinus cancer; (2) squamous cell carcinoma; (3) T4 disease; and (4) curative-intent treatment. The data for 118 patients were obtained from 28 institutions across Japan and analyzed for overall survival and local control rates by local extension site.
  ResultsSites with a poor prognosis included the cribriform plate, dura, nasopharynx, middle cranial fossa, and cranial nerves other than V2. There was a significant correlation among these sites, except for the cranial nerves. Additionally, the hard palate was the only site that correlated with nodal involvement and showed a poor treatment outcome.
  ConclusionEven in cases presenting with similar T4 maxillary sinus cancer, treatment should be performed in consideration of the local extension site. (c) 2013 Wiley Periodicals, Inc. Head Neck 36: 1567-1572, 2014

  英語, 研究論文（学術雑誌）, The efficacy of elective neck irradiation (ENI) for patients with N0 carcinoma of the maxillary sinus has been controversial. The purpose of our study was to investigate the incidence of late neck recurrence and the mortality rate from regional disease in patients with N0 maxillary sinus cancer after superselective cisplatin infusion and concomitant radiotherapy (RADPLAT) without ENI. We retrospectively analyzed 48 patients with N0 maxillary sinus cancer who underwent RADPLAT. Chemotherapy consisted of 100-120 mg/m(2) superselective intra-arterial cisplatin administered at a median rate of four times weekly. Concurrent radiation therapy was administered at a median dose of 65 Gy without ENI. Late neck recurrence was observed in 8.3 % (4/48). Three patients underwent salvage neck dissection and survived without any evidence of disease. The remaining patient did not undergo neck dissection due to coexistence with distant metastasis, and he died of regional disease. The mortality rate from regional disease was calculated to be 2 % (1/48). The incidence of late neck recurrence was not frequent, and the mortality rate from regional disease was low. Salvage neck dissection was considered to be feasible for patients with late neck recurrence. When definitive radiotherapy and concomitant chemotherapy are applied, it is considered that ENI is not required for cases of N0 maxillary sinus cancer.

  英語, 研究論文（学術雑誌）, Purpose: To evaluate the feasibility of arterial spin-labeling (ASL) in head and neck cancer for noninvasive measurement of tumor blood flow (TBF), by comparing 1) the TBF change before and after the treatment, and 2) posttreatment TBF and its reduction rate between residual and nonresidual tumors after treatment.
  Materials and Methods: Twenty-two patients with head and neck cancer were evaluated using ASL on 3.0-T magnetic resonance imaging (MRI) before and after nonsurgical treatment. A pulsed ASL sequence with Look-Locker readout was used to calculate quantitative TBF. TBF reduction rates between pre- and posttreatment values were also calculated. Residual tumors were confirmed when present with either histopathologically or clinical follow-up.
  Results: Pre- and posttreatment mean TBF values were 121.4 +/- 27.8 (standard deviation) and 24.9 +/- 14.9 mL/100g/min, respectively. Pre-and posttreatment TBF differed significantly. Posttreatment TBF was significantly higher in patients with residual tumors (five patients, 46.9 +/- 7.1 mL/100g/min) than in those without (17 patients, 18.4 +/- 9.2 mL/100g/min). The TBF reduction rate was significantly lower in patients with residual tumors (0.540.55 +/- 0.120.12) than in those without (0.85 +/- 0.06).
  Conclusion: ASL allows quantitative assessment of TBF in head and neck cancer. ASL may be useful for noninvasive assessment of tumor viability in head and neck cancer.

  英語, 研究論文（学術雑誌）, The Japan Society for Head and Neck Surgery (JSHNS) started a board certification system for head and neck surgeons in 2010. To become certified, the following qualification and experiences are required: (I) board certification as otorhinolaryngologist, (2) 2 years of clinical experience in a board-certified training facility, (3) clinical care of 100 patients with head and neck cancer under the supervision of board-certified faculty and (4) surgical experience in 50 major head and neck surgical procedures, including 20 neck dissections, under the supervision of board-certified faculty. The following scientific activities are also required during the preceding 5 years: (1) two clinical papers on head and neck cancers presented at major scientific meetings, (2) one clinical paper on head and neck cancer published in a major journal, (3) attendance at two annual meetings of JSHNS and (4) enrolment in three educational programs approved by JSHNS. The qualifying examination consists of multiple choice tests and oral examinations. A total of 151 head and neck surgeons were certified in 2010 followed by 43 in 2011 and 34 in 2012, while the membership of JSHNS dramatically increased from 1201 in 2007 to 1748 in 2013. Although the board certification system for head and neck surgeons was started only recently, it has encouraged many residents and fellows as well as established head and neck surgeons. We believe that this system will contribute to further advancement in the clinical practice for head and neck cancers in Japan. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, Background: The current study sought to assess the role of initial neck dissection (ND) for patients with node-positive oropharyngeal squamous cell carcinomas (OPSCC).
  Methods: The data for 202 patients with previously untreated node-positive OPSCC were gathered from 12 institutions belonging to the Head and Neck Cancer Study Group in the Japan Clinical Oncology Group. These patients were categorized into two groups, consisting of the initial ND group and the wait-and-see group, according to treatment policy.
  Results: Regional recurrence was observed in 17 of 93 patients undergoing initial ND, whereas, recurrent or persistent diseases were observed in 40 of 109 patients who did not undergo initial ND. The 4-year overall survival rates (OS) for the wait-and-see group and initial ND groups were 74.0% and 78.7%, respectively, and the 4-year regional control rates (RC) for each group were 77.6% and 84.9%. There were no significant differences in either OS or RC (p = 0.3440 and p = 0.2382, respectively). However, for patients with N3 disease, the 4-year OS of the initial ND group (100%) was favorable. For patients with N2a disease, the 4-year RC of the initial ND group was higher than that of the wait-and-see group statistically (100% vs 62.5%, p = 0.0156).
  Conclusions: The role of initial ND was limited in patients with node-positive OPSCC. The treatment strategy not involving initial ND is considered feasible and acceptable when nodal evaluation after definitive radiotherapy or chemoradiotherapy is applied adequately. However, it is possible that initial ND improves outcomes in patients with resectable large-volume nodal disease. (C) 2014 Elsevier Ltd. All rights reserved.

  日本語, 魚骨異物は、日常診療においてしばしば遭遇するが、少ないながらも経口腔的に摘出不可能な症例が存在する。今回我々は、頸部外切開を要した魚骨異物の症例を3例経験した。症例は68歳女性、58歳女性、81歳女性で、いずれもカレイの魚骨異物をCTで同定し、頸部外切開にて異物を摘出した。症例2では異物の捜索に難渋したが、手術操作により異物が移動したためと考えられた。症例3では異物は咽頭収縮筋内に完全に迷入し、術中の触診では異物の部位特定が困難であった。ペンローズドレーンを目印として留置して術中CTを撮影し、魚骨の正確な位置を確かめつつ手術を行った。術中CTを3D構築した画像は異物の部位特定に有用であった。(著者抄録)

  日本語, 穿刺細胞診で悪性が確定しなかった場合にも画像的に甲状腺癌が疑わしいなどの理由により手術を行うことが少なくない。術後病理診断と画像所見との関係について比較し、どのような画像所見が癌予測因子として有用であるかについて検討した。対象は甲状腺腫瘍摘出を行ったもののうち、術前細胞診で悪性以外であった58症例。術前エコー検査所見(微細石灰化、辺縁不整、内部low echo、縦横比1以上、Haloの消失)が陽性であった場合に、術後病理で悪性であった陽性適中率(PPV)、陰性であった場合に術後病理が良性であった陰性適中率(NPV)をそれぞれ算出した。前述した各エコー所見のそれぞれのPPVは74、89、71、89、65%。NPVはいずれの所見も51〜58%にとどまった。辺縁不整および縦横比1以上がみられた場合のPPVは89%であり、これらの所見は有用な癌予測因子となりうると考えられた。(著者抄録)

  英語, 研究論文（学術雑誌）, The purpose of this study was to evaluate the incidence of lymph node metastasis among patients with T4 maxillary sinus squamous cell carcinoma (MS-SCC) as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC.
  Consecutive series of all patients (n = 128) with previously untreated T4 maxillary sinus SCC between 2006 and 2007 were obtained from 28 institutions belonging to or cooperating in the Head and Neck Cancer Study Group of the Japan Clinical Oncology Group.
  Of the 128 patients, 28 (21.9 %) had lymph node metastasis, and six patients (4.7 %) had distant metastasis at diagnosis. Among the 111 patients who were treated with curative intent, 98 had clinically N0 neck disease and did not receive prophylactic neck irradiation. A total of 11 patients (11.2 %) subsequently developed evidence of lymph node metastasis, of whom eight were among the 83 patients with an N0 neck and had not received elective neck treatment. There were 15 patients who received an elective neck dissection as part of the initial treatment, of whom three had pathologically positive for lymph node metastases. Of 11 patients, six patients with nonlateral retropharyngeal lymph node metastasis without primary or distant disease were successfully salvaged.
  This study identified the incidence of lymph node metastasis among patients with T4 MS-SCC as well as the delayed metastasis rate and the treatment outcome for untreated N0 neck in patients with T4 MS-SCC. These results will be of assistance in selecting treatment strategy for T4 MS-SCC in the future.

  英語, 研究論文（学術雑誌）, Our aim was to evaluate the feasibility of salvage operations for patients with persistent or recurrent cancer of the maxillary sinus after superselective intra-arterial infusion of cisplatin with concurrent radiotherapy. We retrospectively analysed the records of 61 patients with cancer of the maxillary sinus who were treated in this way. Chemotherapy comprised 100-120 mg/m(2) superselective intra-arterial infusions of cisplatin given a median of 4 times weekly (range 2-5). Concurrent radiotherapy was given in a median dose of 65 Gy (range 24-70 Gy). Persistent or recurrent cancer of the maxillary sinus was found in 17 patients, of whom 11 had salvage surgery. The disease was controlled in 8 of the 11, and 7 of the 11 survived with no evidence of disease. Their 5-year overall survival was 61%. Two of the 11 developed serious operative complications. Salvage surgery for patients with persistent or recurrent cancer of the maxillary sinus treated by superselective chemoradiotherapy is both safe and successful. Salvage surgery is a good option when this sort of persistent or recurrent cancer is followed up after the regimen of chemoradiotherapy described.

  日本語, 研究論文（学術雑誌）, Secondary placement of a voice prosthesis is often difficult to perform due to inability in flexing the neck after total laryngectomy and radiation therapy. We report a technique of secondary voice prosthesis placement using a curved rigid esophagoscope. An endotracheal tube and a flexible endoscope are inserted into the esophagus. In creating a tracheoesophageal puncture, a sharp forceps is inserted through the tip of esophagoscope. Then, a guide wire is introduced through the esophagoscope and the voice prosthesis is placed by back-loading method. This method is safe and easy because there is no risk of perforation through the posterior esophageal wall.

  英語, 研究論文（学術雑誌）, OBJECTIVE: Fine-needle aspiration cytology (FNAC) is considered to be the most reliable method of examination for thyroid nodules. However, when thyroid nodules are evaluated as Bethesda I-V, the role of ultrasonography is considered to be enhanced. We investigated the association between a number of ultrasonographic (US) characteristics and the risk of thyroid malignancy, and assessed the optimal compromise on the number of US characteristics for predicting thyroid malignancy. METHODS: Seventy-three patients, whose thyroid nodules were evaluated as Bethesda I-V by FNAC prior to surgery, were treated surgically. A number of US characteristics, such as microcalcification, irregular margins, hypoechogenicity, a taller-than-wide shape, and the absence of halo sign, were assessed before surgery. The optimal compromise on the number of US characteristics was analyzed using a receiver operating characteristics (ROC) curve. The area under the ROC curve (AUC) represents the overall discriminatory ability of a test. RESULTS: The risk of malignancy was 11.8% in patients without any US characteristics, 44.4% in those with one characteristic, 61.5% in those with two characteristics, 75% in those with three characteristics, 90% in those with four characteristics, and 100% in those with five characteristics. The AUC was favorable (0.81599). At least two US characteristics were revealed to be the optimal compromise on the number of US characteristics based on the ROC curve. CONCLUSION: We proved the role of the number of US characteristics in predicting thyroid malignancy. It was thought that a surgical approach should be considered for patients with at least two US characteristics.

  英語, 研究論文（学術雑誌）, Objective: To evaluate postoperative hearing outcomes after lateral temporal bone resection (LTBR) with reconstruction of the external auditory canal (EAC) and conductive function for early-stage EAC carcinoma. Methods: We retrospectively examined patients diagnosed with early-stage EAC carcinoma treated with surgery alone between January 2006 and December 2012. Patients who had postoperative adjuvant chemotherapy and/or radiotherapy were excluded. Patients receiving LTBR in combination with tympanoplasty were divided into two groups based on the reconstruction of the EAC with and without (w/o) split-thickness skin grafts (STSGs). Audiological data included the preoperative hearing thresholds and the most recent postoperative hearing thresholds obtained at least 12 months after surgery. The hearing outcome was evaluated based on puretone audiograms using the Committee on Hearing and Equilibrium guidelines of the American Academy of Otolaryngology-Head and Neck Surgery for the evaluation of the results of treatment of conductive hearing loss. The postoperative quality of life (QOL) for patients was evaluated using the Glasgow Benefit Inventory (GBI). Results: All patients (n = 15) achieved disease-free survival without significant morbidity or mortality. When we compared the mean air-bone gaps after surgery, those in the STSG group (n = 8) were found to be significantly lower than those in the w/o STSG group (n = 7; p < 0.001). The success rate for postoperative hearing was 75.0% in the STSG group, which was significantly higher than that in the w/o STSG group (p = 0.014). All patients in the w/o STSG group showed stenosis and closure of the EAC at fewer than 10 months after surgery. In contrast, all patients in the STSG group showed preserved conformation of the new EAC for more than 12 months after surgery. When we compared the mean GBI score between the two groups of patients, the overall and general health scores in the STSG group were found to be significantly higher than those in the w/o STSG group (p = 0.021, p = 0.001). Conclusions: Reconstruction of the EAC using a rolled-up STSG technique in combination with tympanoplasty after LTBR is useful for hearing preservation and the observation of locoregional lesions after surgery, resulting in improved QOL for patients.

  日本語, 研究論文（学術雑誌）, HPV関連中咽頭癌の多くはp16が過剰発現していることから、p16がHPV感染のsurrogate markerであると考えられている。しかし、p16発現の判定基準は統一されておらず、HPV感染以外の機序でもp16が過剰発現することもある。今回われわれは中咽頭扁平上皮癌91例に対してHPV感染とp16の発現について検討した。91例中HPV陽性であったのは29例(32%)で、p16陽性であったのは31例(34%)であった。HPV陽性であった29例中24例(83%)がp16陽性で、HPV陰性であった62例中7例(11%)がp16陽性であった。3年粗生存率はp16陽性例が82.2%、p16陰性例が65.1%でp16陽性例の方が有意に生存率は良好であったが、HPV陰性p16陽性例の予後はHPV陰性p16陰性例と同様に不良であった。以上のことからp16の発現がHPV感染の完全なsurrogate markerとはなり難いと考えられた。(著者抄録)

  英語, 研究論文（学術雑誌）, The current study aimed to assess the role of salvage surgery for failure cases of oropharyngeal cancer (OPC) undergoing initial chemoradiotherapy (CRT).
  The data for 523 patients with previously untreated OPC were gathered from 12 institutions belonging to the Head and Neck Cancer Study Group in Japan Clinical Oncology Group (JCOG).
  Of the 170 patients who received CRT, 35 patients (21 %) had local recurrence or residual disease. Only 11 patients underwent further salvage surgery, and 24 patients received nonsurgical treatment. There were statistically significant differences between the two groups in terms of patient age and the presence of a simultaneous regional recurrence. The 5-year overall survival rates for the patients who underwent salvage surgery were 49.1 %, whereas those for the patients who received nonsurgical treatment were 16.3 %.
  The initial treatment method for OPC should be decided carefully and the limitations of salvage surgery should be fully considered.

  英語, 研究論文（学術雑誌）, The prevalence of oropharyngeal carcinoma is rising in western Europe and the United States, where there appears to be a strong association between human papillomavirus (HPV) and oropharyngeal squamous cell carcinoma (OPSCC). However, such a correlation has not yet been fully evaluated in Japan.
  We performed a retrospective analysis of the association between tumour HPV status and the demographic and clinicopathological parameters of 71 patients with OPSCC at Hokkaido University Hospital, Japan, between 1998 and 2009. The parameters included age, gender, survival, tumour subsite, tumour-node-metastasis (TNM) stage, smoking history, second primary tumour status, recurrence/residual disease at the primary site, and overall survival. HPV status was established by multiplex polymerase chain reaction (PCR) analysis.
  Of the 71 oropharyngeal cancers, 20 were positive for HPV-16, two for HPV-18, and one for HPV-58. Kaplan-Meier survival analysis showed improved overall survival rates in patients with HPV-positive tumours (p = 0.0038) compared with HPV-negative tumours. Of the 45 patients who received chemoradiotherapy, HPV-positive patients experienced better overall survival than HPV-negative patients (p = 0.0032). In a multivariate analysis, the survival benefit of HPV-positive patients was independent of age and T and N classification.
  HPV status is a significantly favourable prognostic factor in oropharyngeal cancer and could be used as a marker to optimize the treatment of patients with this type of cancer in Japan.

  英語, 研究論文（学術雑誌）, Conclusion: It was proved that cyclin D1-positive status in surgical margins was an independent prognostic indicator of local recurrence. The expression of cyclin D1 in tumor-free surgical margins may better predict local recurrence in patients with head and neck squamous cell carcinoma (HNSCC) after surgical treatment with curative intent. Objective: This retrospective study aimed to determine the prognostic indicators for local recurrence in HNSCC. Methods: A total of 116 HNSCC patients who underwent surgical treatment with curative intent and had histopathologically tumor-free margins were eligible for this study. The expression of p53 and cyclin D1 was assessed by immunohistochemical staining in surgical margins as well as in tumor specimens. Results: In all, 63 patients (54.3%) had p53-positive tumor specimens and 34 patients (29.3%) had p53-positive margins. Seventy-six patients (65.6%) had cyclin D1-positive tumor specimens and 54 patients (46.6%) had cyclin D1-positive margins. A significant difference in local control rates was observed between patients with cyclin D1-positive and -negative margins (77.2% vs 91.5%, log rank test, p = 0.0139). Multivariate Cox proportional hazards testing indicated that the hazard ratio of cyclin D1-positive margins for local recurrence was 4.58 (95% confidence interval 1.14-21.69, p = 0.0304).

  日本語, HPV陽性中咽頭癌は陰性例に比べ予後が良好であるが、陽性例であっても予後不良例も存在する。Spectorらは"matted nodes"というリンパ節の転移様式のみられる症例は遠隔転移しやすく予後不良であると報告した。中咽頭扁平上皮癌症例61例に対してretrospectiveに"matted nodes"および臨床的検討を行った。このうち"matted nodes"を認めたのは9例であった。全症例における"matted nodes"の有無別の生存率には有意差を認めなかったが、"matted nodes"あり群の方が有意に遠隔転移しやすい傾向にあった。HPV陽性例のみでの検討では"matted nodes"あり群の方がなし群に比べ有意に予後が不良であった。HPV陽性であっても"matted nodes"のある症例は遠隔転移のリスクが高く予後不良であるので導入化学療法を行った方が望ましいと考えられた。(著者抄録)

  英語, 研究論文（学術雑誌）, Objective: To assess the efficacy and safety of cetuximab in combination with cisplatin and 5-fluorouracil for first-line treatment of Japanese patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck. Methods: In this open-label, single-arm, multicenter, Phase II study conducted in Japan, patients with confirmed recurrent and/or metastatic squamous cell carcinoma of the head and neck received weekly cetuximab (week 1, 400 mg/m2
  subsequent weeks, 250 mg/m2) plus a maximum of six three-weekly cycles of cisplatin (100 mg/m2, day 1) and 5-fluorouracil (1000 mg/m2/day, 24-h infusion, days 1-4). The primary endpoint was the best overall response assessed by an independent review committee according to the modified World Health Organization criteria. Results: In total, 33 patients received treatment. The most frequent primary tumor site was the hypopharynx (42%), and most patients had metastatic disease (85%). The best overall response rate as assessed by the independent review committee was 36% (95% confidence interval: 20, 55) and was significantly greater (P = 0.002) than the protocol-specified threshold of 15% at the one-sided 5% level. The disease control rate was 88%. The median progression-free survival and overall survival were 4.1 and 14.1 months, respectively. There were no unexpected safety concerns. Grade 3 or 4 adverse events were experienced by nearly all patients (32, 97%). No adverse events were fatal. Conclusions: The demonstrated efficacy and safety of cetuximab in combination with cisplatin and 5-fluorouracil for the first-line treatment of Japanese patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck justify the further use of this combination treatment in this patient population (ClinicalTrials.gov number, NCT00971932). © The Author 2013.

  英語, 研究論文（学術雑誌）, Objectives: Although three-weekly high-dose (100 mg/m(2)) cisplatin (three cycles) chemoradiotherapy has been considered a standard regimen for patients with advanced head and neck squamous cell carcinomas (HNSCC), this protocol is associated with significant acute and late toxicities. Therefore, weekly cisplatin at a dose of 40 mg/m(2) has been used at our institution since 2006. This retrospective study was aimed at assessing the oncologic efficacy of weekly cisplatin chemoradiotherapy for the control of nodal metastasis.
  Methods: We analyzed 28 patients with node-positive HNSCC treated with weekly cisplatin and concurrent radiotherapy. Computed tomography was performed 4-8 weeks after the completion of chemoradiotherapy to evaluate nodal response. If residual neck disease was apparent or suspected, we performed early salvage neck dissection (ND). In cases with a complete response (CR), we took a "wait and see" approach. When no viable tumor cells were observed in the surgical specimens obtained by ND, nodal metastasis was defined as controlled by weekly cisplatin chemoradiotherapy alone.
  Results: Nodal metastasis was evaluated as having a CR in 20 patients (71%). Eight patients (29%) underwent early salvage ND. Recurrent primary tumors were observed in the other four patients (14%). Salvage primary resection and associated ND were performed for these four patients. In 7 of 12 patients undergoing ND, no viable tumor cells were observed. In 23 of 28 patients, neck diseases were controlled by chemoradiotherapy alone (not including salvage by ND). In 27 of 28 patients, neck diseases were controlled by the overall treatment (including salvage by ND). The rate of nodal control by chemoradiotherapy alone and by the overall treatment was found to be 82.0% and 96.3%, respectively, using the Kaplan-Meier method. The three-year overall and disease free survival rates were 86.8% and 80.8%, respectively.
  Conclusion: Concomitant weekly cisplatin at a dose of 40 mg/m(2) chemoradiotherapy showed a good control rate of not only primary lesions but also neck diseases. (C) 2012 Elsevier Ireland Ltd. All rights reserved.

  英語, Background: The purpose of this study was to evaluate the efficacy of superselective cisplatin infusion with concomitant radiotherapy (RADPLAT) for previously untreated patients with the squamous cell carcinoma of maxillary sinus (SCC-MS). Methods: Between 1999 and 2010, 54 patients were given superselective intra-arterial infusions of cisplatin (100-120mgm(-2) per week) with simultaneous intra-venous infusions of thiosulfate to neutralise cisplatin toxicity and conventional radiotherapy (65-70 Gy). Results: One patient (1.9%) was diagnosed with T2, 14 (25.9%) with T3, 27 (50%) with T4a, and 12 (22.2%) with T4b disease. Lymph-node involvement was present in 12 patients (22.2%). During the median follow-up period of 6.4 years, the 5-year local progression-free and overall survival rates were 65.8 and 67.9% for all patients, respectively. No patient died as a result of treatment toxicity or experienced a cerebrovascular accident. Osteonecrosis (n-5), brain necrosis (n-1), and ocular/ visual problems (n = 14) were observed as late adverse reactions. Conclusion: We have shown excellent overall survival and local progression-free rate in SCC-MS patients treated by RADPLAT with acceptable rates of acute and late toxicity. A multi-institutional trial is needed to prove that this strategy is a feasible and effective approach for the treatment of SCC-MS.

  英語, 研究論文（学術雑誌）, Objective: The current study aimed to compare the therapeutic outcomes of surgery with those of chemoradiation for patients with advanced oropharyngeal cancer (OPC). Methods: The data for 523 patients with previously untreated OPC were obtained from 12 institutions belonging to the Head and Neck Cancer Study Group in the Japan Clinical Oncology Group from April 2005 to March 2007. In this study, we matched a group of patients who underwent surgery with a second group treated with chemoradiation according to age, gender, subsite, and T and N classification, and analyzed the overall survival, progression-free survival, local control and swallowing function. Results: The final matched-pair analysis included 186 patients. The 5-year overall survival, progression-free survival and local control rates were 69.8 and 71.4% (p = 0.762), 51.0 and 54.4% (p = 0.531), and 75.2 and 80.3% (p = 0.399), respectively, in patients treated with surgery and those treated with chemoradiation. Swallowing function in patients treated with chemoradiation was significantly better than that in patients treated with surgery (p = 0.015). Conclusion: Although this study was not randomized, this matched-pair analysis of patients treated with surgery or chemoradiation showed that chemoradiation is as effective as surgery in the treatment of OPC.

  日本語, 研究論文（学術雑誌）, Background : The concept of sentinel node (SN) has been established in oral cancer. This study aimed to investigate distribution of the area where SN was located. Method : Ten patients with T1-2 N0 tongue cancers underwent SN biopsy following partial glossectomy. SNs were detected using gamma camera and gamma probe and were analyzed pathologically. Result : SN was localized in 9 submandibular, 14 upper jugular, 5 middle jugular, 1 lower jugular area in disease side. SN was also localized in 1 upper jugular, and 1 middle jugular area in the opposite side. Occult SN metastasis was observed in 6 of 10 patients (60%). Conclusions : It was concluded that the most likely site where SN was detected was upper jugular area in disease side.

  International Cancer Conference Journal, 1, 4, 215, 219, Springer, 2012年10月
  英語, Squamous cell carcinoma of the nasal vestibule (SCC-NV) is rare among head and neck malignancies. It behaves differently from cancers arising in the nasal cavity and paranasal sinuses, and skin cancer of the external nose. Prognosis is more favorable than nasal cavity tumors and less favorable than skin cancers. We experienced two cases of SCC-NV who were treated with rapid superselective high-dose cisplatin infusion with concomitant radiotherapy (RADPLAT). A 56-year-old male and a 68-year-old female with SCC-NV, classified as T4aN0M0 according to UICC and T2 according to Wang classification, were given superselective intra-arterial infusions of cisplatin, with simultaneous intravenous infusions of thiosulfate to neutralizecisplatin toxicity, together with conventionalradiotherapy. In both cases, the internal maxillary artery and the facial artery were considered to be feeders of the tumor. No serious adverse events have been observed in either patient to date during follow-up of 7.3 and 5.3 years, respectively. Both patients are alive without disease and show excellent cosmetic results. RADPLAT is considered to be useful for the treatment of patients with SCC of the nasal vestibule.

  日本語, 頭頸部癌における化学放射線併用療法(CRT)では粘膜炎により経口摂取困難をきたすため、胃ろうを造設することも少なくない。胃ろうと栄養状態・完遂率との関連について北海道大学病院において平成18年6月から平成23年1月までの間にCRTを施行した声門上癌、中咽頭癌、下咽頭癌52例についてレトロスペクティブに検討した。胃ろう使用群は非使用群と比較して治療前からの体重、アルブミン値が有意に低下を認め、当科での現在の胃ろうの使用方法をより栄養状態を向上のため工夫する必要があると考えられた。また、胃ろう留置群は非留置群よりも有意にCRT完遂率が高く、胃ろう造設がCRT完遂に寄与していると考えられた。原発部位別に見ると、声門上癌・下咽頭癌では胃ろう造設はCRT完遂に寄与しており、中咽頭癌では胃ろうを留置してもCRT完遂率は十分ではなく、今後検討が必要と思われる。(著者抄録)

  英語, 研究論文（学術雑誌）, Conclusion: We conclude that intra-arterially injected cisplatin passed via lymph flow into sentinel nodes (SNs) as the platinum concentration in the SNs was higher than that in the non-sentinel nodes (NSNs). It is possible that preoperative intra-arterial chemotherapy targeting primary cancer also has a therapeutic effect on subclinical metastatic SNs. Objectives: Intra-arterial chemoradiotherapy has been reported to be effective against not only primary tumors but also nodal metastases. We considered the hypothesis that intra-arterially injected cisplatin passed via lymph flow into regional nodes. This study aimed to investigate intra-arterially injected cisplatin distribution to regional nodes by comparing platinum concentrations in SNs and NSNs. Methods: Five patients with T1-2 N0 tongue cancer were treated with preoperative intra-arterial chemotherapy (cisplatin, 100 mg/m(2)) targeting primary cancer. Partial glossectomy together with SN biopsy and elective neck dissection were performed 2 weeks after intra-arterial chemotherapy. Platinum concentrations in the lymph nodes were measured using a Zeeman atomic absorption spectrometer. Results: Thirteen SNs were harvested together with eight NSNs from the areas adjacent to the SNs. Platinum concentrations were then measured, revealing a significant difference in platinum concentration between the SNs and the NSNs (mean +/- SD, 0.682 +/- 0.246 mu g/g vs 0.506 +/- 0.274 mu g/g; p = 0.049).

  英語, 研究論文（学術雑誌）, This retrospective study aimed to compare the accuracy of two nodal evaluation criteria using computed tomography after intra-arterial chemoradiation in node-positive head and neck squamous cell carcinomas. Computed tomography was used to evaluate radiographic nodal response 4-8 weeks after intra-arterial chemoradiation. We compared the accuracy of two different criteria: criterion 1 (radiographic complete response was recorded in the absence of focal abnormalities and if the maximum diameter of the metastatic node was less than 15 mm), and criterion 2 (radiographic complete response was recorded in the absence of focal abnormalities and if the minimum diameter of metastatic nodes was less than 7 mm in level II and if the minimum diameter of metastatic nodes in the rest of the neck was less than 6 mm). Positive predictive values were criterion 1: 69.2%, criterion 2: 47.8%; negative predictive values were criterion 1: 88.5%, criterion 2: 90.5%. Positive likelihood ratios were criterion 1: 7.50, criterion 2: 3.06. The difference between each criteria was statistically significant using McNemar's test ( = 0.0016). Computed tomography evaluation accuracy of nodal response after intra-arterial chemoradiation was comparable to recent reports, and it was feasible to perform salvage neck dissection by computed tomography evaluation for nodal response. We recommend using criterion 1 because of its simplicity and reliability.

  日本語, Intractable nausea and vertigo induced by opioid treatment are occasionally difficult to treat. It has been reported that antiemetic drugs and opioid rotation may be effective in treating nausea in such cases; however, this approach has been occasionally ineffective. Symptomatic treatment has not been developed for vertigo induced by opioid treatment. Here, we report a case study where combined treatment with perospirone and a histamine H₁ receptor antagonist was used in 2 patients who developed intractable nausea and vertigo induced by opioid treatment. Treatment with a histamine H₁ receptor antagonist drug (tablet form, containing 40 mg diphenhydramine salicylate and 26 mg diprophylline) suppressed the nausea and vertigo. However, increasing the opioid dosage exacerbated the symptoms, and treatment involving the histamine H₁ receptor antagonist and opioid rotation was ineffective. Subsequently, combination treatment with the histamine H₁ receptor antagonist (3 tablets per day) and perospirone (maximum daily dose, 16 mg) improved the symptoms. The results of the present study suggest that combination treatment with a histamine H₁ receptor antagonist and perospirone might improve intractable nausea and vertigo induced by opioid treatment.

  英語, 研究論文（学術雑誌）, Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is characterized by systemic necrotizing vasculitis, and patients fall into 2 groups: those with proteinase 3-ANCA and those with myeloperoxidase-ANCA. As infections are a trigger of ANCA-associated vasculitis, this disease tends to localize in areas around the upper airway. In this study, the authors compared ear and nasal symptoms between patients with proteinase 3-ANCA and those with myeloperoxidase-ANCA. We undertook a retrospective case series study of 34 patients diagnosed with ANCA-associated vasculitis. The otologic symptoms were divided into 3 types: chronic otitis media, secretory otitis media, and sensorineural hearing loss. Chronic otitis media was more common in patients with proteinase 3-ANCA (P=.001), whereas secretory otitis media was more frequently found in patients with myeloperoxidase-ANCA (P=.007). Crust formation (P=.001), saddle nose (P=.024), and sinusitis (P=.001) were more common in patients with proteinase 3-ANCA than in those with myeloperoxidase-ANCA. Marked differences were observed in the disease spectrum between the 2 ANCA groups.

  英語, 研究論文（学術雑誌）, Background: The aim of this multi-center phase II study was to clarify the clinical benefit of an opioid-based pain control program for head and neck cancer patients during chemoradiotherapy.
  Patients and methods: Head and neck cancer patients who were to receive definitive or postoperative chemoradiotherapy were enrolled. The opioid-based pain control program consisted of a three-step ladder, with basic regimens of:
  Step 1: acetaminophen at 500-1000 mg three times a day.
  Step 2: fast-acting morphine at 5 mg three times a day before meals for a single day.
  Step 3: long-acting morphine administered around-the-clock, with a starting dosage of 20 mg/day and no upper limit set in principle.
  Patients and methods: The primary endpoint of this study was compliance with radiotherapy.
  Results: A total of 101 patients from 10 institutions were registered between February 2008 and May 2009 and included in the analysis. The major combination chemotherapy regimen was cisplatin alone (76%). The rate of completion of radiotherapy was 99% and the rate of unplanned breaks in radiotherapy was 13% (13/101, 90% confidence interval: 9.9-16.5%). Median maximum quantity of morphine used per day was 35 mg (range 0-150 mg).
  Conclusions: Use of a systematic pain control program may improve compliance with CRT. (C) 2011 Elsevier Ireland Ltd. All rights reserved. Radiotherapy and Oncology 101 (2011) 410-414

  日本語, 唾液導管癌は乳癌に類似する予後不良な悪性腫瘍である。近年乳癌と同様に唾液導管癌においてもHER2の発現が報告されているため、今回われわれは手術標本を用いて免疫染色を行いHER2の発現を解析し臨床背景と検討した。その結果、唾液導管癌5例中HER2陽性例は3例であった。病理組織別のHER2陽性率は唾液導管癌で60%、腺様嚢胞癌で0%、粘表皮癌で17%、腺癌で38%であった。また病理学的悪性度による比較ではHER2陽性例は全て高悪性度群に、HER2陰性例は全て低悪性度群に属しHER2の過剰発現と病理学的悪性度との関連が示唆された。HER2陽性唾液導管癌に対する抗HER2抗体を用いた治療法の開発が強く望まれる。(著者抄録)

  英語, 研究論文（学術雑誌）, Objective: The most common chemoradiotherapy regimen is high-dose (100 mg/m(2)) three-weekly cisplatin with concomitant radiotherapy; however, this protocol is associated with acute and late toxicities. Here, we reviewed the dose intensity and toxicity for concomitant weekly cisplatin and radiotherapy in patients with head and neck cancer.
  Methods: Fifty-three patients with untreated head and neck cancer were enrolled and evaluated at our institution from April 2006 to April 2010. Weekly cisplatin (40 mg/m(2)) was given on weeks 1, 2, 3, 5, 6 and 7 with radiotherapy, which comprised a standard dose of 70 Gy delivered in 35 daily fractions over 7 weeks.
  Results: Fifty-one patients (96.2%) received the full dose of radiotherapy, while the course was disrupted by adverse events in two. Over the course of the chemotherapy, 31 patients (58.5%) received more than 200 mg/m(2) cisplatin. The toxicity was manageable in all except one patient, who died of sepsis after completing treatment. The 2-year overall survival rate and local progression-free rate for all patients were 93.7% and 88.0%, respectively. The primary site showed a complete response in 52 patients (98.1%) and a partial response in 1 patient (1.9%). The primary disease was well controlled by chemoradiotherapy in 47 patients (88.7%).
  Conclusions: Weekly cisplatin could be easier to manage than three-weekly cisplatin, because patients can be monitored more regularly for toxicity allowing the schedule to be altered if required. This regimen appears to be a suitable alternative to three-weekly high-dose cisplatin with concomitant radiotherapy.

  英語, 研究論文（学術雑誌）, The treatment of base of tongue (BOT) cancer is highly controversial with differing options according to individual institutions, or the primary surgical or radiation therapy bias. We aimed to determine patient outcomes and discuss technical aspects following treatment with concurrent radiation therapy and targeted cisplatin chemotherapy (RADPLAT).
  We utilized RADPLAT for the definitive treatment of patients with BOT cancers. The 5-year local control and overall survival rate was 92.3% and 90.9% for all patients, respectively, and all surviving patients achieved normal swallowing without a feeding-tube and normal speech without tracheostoma after treatment.
  Our study found that RADPLAT gave excellent survival rates and organ functions for patients with BOT cancers. We consider that BOT cancer is a good indication for RADPLAT and that the angiographic technique and patient selection are keys to success. (C) 2011 Elsevier Ltd. All rights reserved.

  日本語, 化学放射線療法後の救済手術においては皮膚切開のデザインは、特別な配慮が必要である。われわれの救済手術を行う際の皮膚切開のデザインの基本的なコンセプトは以下のとおりである。(1)胸部の皮膚を上方に進展して利用できるようなデザインにする。(2)皮膚縫合線が再建組織の上にのるようにする。(3)必ずしも3ポイントは禁忌ではない。ただし、それぞれの皮弁先端の血流が維持されるように、かつ、再建組織の上に3ポイントがくるようにする。術後合併症を避けるためには、手術中の手技のみならず、皮膚切開のデザインなどの手術の戦略も同様に重要である。(著者抄録)

  日本語, 頭頸部悪性腫瘍の初期症状としての嗄声・呼吸困難を中心に、診察の進め方、対応について解説した。嗄声については、問診・診察の際には、癌を常に念頭に置きながら進めていくことが大切である。癌を疑う場合には、ファイバースコープでじっくりと十分に観察する。初期の癌の可能性を完全には否定できない場合には、時間をあけて定期的に診察するのが望ましい。喫煙は、癌を含め嗄声の原因となっていることが多く、生活指導も重要である。声帯麻痺は、頭頸部領域のみならず、肺癌、食道癌、縦隔腫瘍、胸部大動脈瘤など胸部疾患が原因であることも多く、胸部を含めた精査をしなくてはならない。呼吸困難については、様々な要素を考慮しながら気管切開を行うか否か、いつ行うかを判断することが求められる。(著者抄録)

  英語, 研究論文（学術雑誌）, We retrospectively investigated treatment outcomes in patients with glottic T1 carcinoma treated with 65 Gy in 26 fractions four times a week and discuss the importance of the overall treatment time.
  Two hundred one patients with glottic T1 carcinoma were evaluated. Sixty-five Gray in 26 fractions were delivered for 200 patients, whereas 1 patient received 62.5 Gy in 25 fractions. We delivered radiotherapy once daily four times a week in this period, for a weekly dose of 10 Gy. Weekdays except Wednesday were treatment days.
  The overall survival rate was 96.8 +/- 1.3% (standard error) at 3 years and 90.8 +/- 2.2% at 5 years. The local control rate was 91.9 +/- 2.0% at 3 years and 89.8 +/- 2.3% at 5 years. In patients with an overall treatment time equal to or longer than 47 days, the local control rate was 82.6 +/- 6.0% at both 3 and 5 years. In the patients with overall treatment time equal to or less than 46 days, the local control rate was 94.6 +/- 1.9% at 3 years and 91.8 +/- 2.4% at 5 years. There was a significant difference between these two groups (P = 0.0349). A severe late radiation reaction occurred in one patient. He experienced severe laryngeal edema that required tracheotomy at 6 months after the completion of radiotherapy. The tracheotomy was closed at 14 months after completion of radiotherapy.
  Overall treatment time seems to be an important factor for a good local control rate for glottic T1N0 carcinoma even when treated with slight hypofractionation.

  日本語, 研究論文（学術雑誌）, The 14 cases of malignant submandibular tumor whose treatment outcome we analyzed between 1989 and 2008 uncluded 5 of adenoid cystic carcinoma, 3 of squamous cell carcinoma, 2 each of mucoepidermoid carcinoma, and carcinoma ex pleomorphic adenoma, and 1 each of carcinosarcoma and large-cell carcinoma. One subject was diagnosed with T1, 7 with T2, 4 with T3, and 2 with T4. Lymph node involvement occurred in 5, -1 with N1 and 4 with N2. None had distant metastasis on the first visit. Seven were treated by surgery alone, 3 by surgery followed by radiotherapy, 2 by surgery followed by radio-and chemotherapy, and 1 by optimized supportive care. The surgical resection area was decided by tumor extension. Neck dissection was done in 9. Overall 5-year survival for all cases based on the Kaplan-Meier method was 57%. All with carcinoma ex pleomorphic adenoma, carcinosarcoma, or large-cell carcinoma remain alive. For those with adenoid cystic carcinoma 5-year survival is 80%, with mucoepidermoid carcinoma 50%, with squamous cell carcinoma 0%, and with carcinosarcoma 0%, respectively. The 5-year survival for stage I subjects was 100%, for stage II 83%, for stage III 50%, and for stage IV 0%. Surgical resection and postoperative radiotherapy were done in cases of minimal extraglandular extension or microscopically positive margins, with satisfactory results. Treatment efficacy for high-grade and advanced stage, however, requires more inprovement.
• 術後感染予防に対するレボフロキサシン(クラビット)の術前単回投与の有用性について

  耳鼻と臨床, 56, 6, 254, 258, 耳鼻と臨床会, 2010年11月
  日本語, レボフロキサシン(LVFX、クラビットR)は、幅広い抗菌スペクトラムを示す経口キノロン系抗菌薬である。1回投与量を増すことで高い血中濃度を得られ、殺菌力は用量依存的である。諸外国では以前より1回500mg以上の単回投与が行われており、本邦でも500mg単回投与が認可された。今回、われわれはこの様なLVFXの特徴に注目し、術後感染予防を目的として使用した。2008年1月から2009年12月末までに頭頸部領域の清潔手術36例(耳下腺13例、甲状腺7例、リンパ節摘出術6例、顎下腺4例、頸部郭清1例、その他5例)において、LVFX500mgを術後感染予防抗菌薬として手術2時間前に1回のみ投与した。その結果、36例全例に感染兆候は認められなかった。また、術後経過で特に問題となるような有害事象もなかった。LVFX500mgの1回のみの内服で、頭頸部領域の清潔手術の術後感染予防薬として十分であることが示唆された。(著者抄録)

  日本語, 2000年から2009年1月までに超選択的動注化学療法と放射線の同時併用療法を下咽頭原発扁平上皮癌新鮮例34例に行った。観察期間は1年3ヵ月-6年4ヵ月(中央値:3年7ヵ月)で、粗生存率(5年)は42.8%で、RADPLATによる局所制御率(5年)は77.8%であった。N0-1症例(10例)は全例生存しているが、N2b-3(24例)の5年生存率は19%と不良であった。下咽頭癌への動注は難しく、リスクも他の部位よりもやや高いといえる。最近は、T4a以下かつN1以下で、原発巣が片側に限局している動注のメリットを発揮できる症例を適応としている。(著者抄録)
• Salvage surgery for local recurrence after chemoradiotherapy or radiotherapy in hypopharyngeal cancer patients

  EUROPEAN ARCHIVES OF OTO-RHINO-LARYNGOLOGY, 267, 11, 1765, 1769, SPRINGER, 2010年11月, ［査読有り］
  英語, 研究論文（学術雑誌）, This retrospective study aimed to assess the role of salvage surgery for local recurrence in hypopharyngeal cancer (HPC) patients who had received radiotherapy (RT) or concomitant chemoradiotherapy (CRT) as an initial treatment. The local recurrence rate, salvage rate after local recurrence and overall survival rate were investigated in 104 HPC patients who received treatment between 1991 and 2005. Local recurrence in the primary site was observed in 41 patients (rate, 39.4%) of whom only 12 could undergo further salvage surgery. Disease control was achieved in seven of these patients (successful salvage rate, 17.1%). The 5-year overall survival rate was 40.6% in the RT/CRT patient group and successful salvage rates for T1, T2, T3 and T4 primary disease were 33.3% (1/3), 20.0% (4/20), 16.7% (2/12) and 0% (0/6), respectively. Severe postoperative complications such as pharyngo-cutaneous fistula were seen in six patients (50.0%). Prognosis of patients with locally recurring HPC after RT/CRT is poor at any primary T-stage and the incidence of postoperative complication is relatively high. This should be taken into consideration when the initial treatment plan is decided and the choice of salvage surgery for such recurrent cases should be carefully determined.

  英語, 研究論文（学術雑誌）, Purpose: Deciding on treatment carcinoma of the tongue when the tumor has a thickness of 1.5 cm or more is difficult. Surgery often requires wide resection and re-construction, leading to considerable functional impairment. A cesium implant is an attractive option, but according to the Manchester System, a two plane implant is needed. Materials and Methods: According to the textbook, a tumor is sandwiched between the needles, which are implanted at the edge of the tumor. This may cause an unnecessarily high dose to the outer surface of the tongue, which sometimes leads to a persistent ulcer. To avoid this complication, we invented a modified implantation method, and applied the method to five consecutive patients. Results: With a minimum follow-up of 2 years, all primary tumors in 5 consecutive patients have been controlled. No complications occurred in soft tissue of the tongue or in the mandible. Conclusion: Our modified Manchester System was feasible and effective for tumors that has a thickness of 1.5 cm or more.

  日本語, 著者らは1998年1月〜2007年12月に根治治療を施行した中咽頭癌新鮮例157例(平均年齢62歳)を対象に後方視的に検討した。1)5年粗生存率は1989〜1996の成績と比較して52%から65%と改善し、特に前壁癌で30%から59%と著明に改善していた。2)前壁癌の約4割にはRADPLATが施行されており、治療成績向上に寄与したものと考えられた。3)治療別の検討では早期癌に対しては手術が最も良い生存率であり、進行癌に対しては経静脈的なCRTに比べてRADPLATによる生存率、局所制御率が高かった。特に腫瘍の栄養血管が比較的単純な前壁癌や側壁癌にはRADPLATが良い適応と考えられた。4)原発の再発率は17%、その救済率は35%で、主にT3-4症例の原発再発の救済はほとんどできていなかった。また頸部の再発率は16%で、その救済率は26%であった。したがって、原発の再発に対してはRADPLATの側壁癌への適応の拡大や再発の早期発見による救済手術、強力な化学療法の開発等が必要であると考えられた。

  英語, 研究論文（学術雑誌）, The objectives of this study were to determine the maximum tolerated dose (MTD) and recommended dose (RD) of S-1 plus cisplatin (CDDP) and to evaluate safety and efficacy using the defined RD in advanced/recurrent head and neck cancer (HNC).
  S-1 was administered orally at 40 mg/m(2) twice daily for 14 consecutive days, and CDDP was infused on day 8 at a dose of 60 and 70 mg/m(2). Each course was repeated every 4 weeks.
  A total of 38 patients were registered, 10 patients for the Phase I study and an additional 28 patients for the Phase II study. Although no dose-limiting toxicity (DLT) was observed in the CDDP 60 mg/m(2) (Level 1) group, two of six patients in the CDDP 70 mg/m(2) (Level 2) group exhibited DLT (fatigue/diarrhea). The MTD was not achieved in the Phase I study. Level 2 was therefore determined as the RD. In the Phase II study, 34 patients, including 6 patients from the Phase I study, were evaluated. At the termination of treatment, the confirmed response rate was 44.1% (15/34, 95% CI: 27.4-60.8). The best response rate without an adequate duration time was 67.6% (95% CI: 51.9-83.4). The median survival period was 16.7 months, and the 1-year survival rate was 60.1%. The main toxicities of Grade 3 or above were anorexia (26.5%), nausea (14.7%), neutropenia/thrombocytopenia (11.8%) and anemia/fatigue (8.8%).
  This is considered to be an effective regimen with acceptable toxicities for HNC.

  英語, 研究論文（学術雑誌）, Background. Comorbidity has an impact on survival in laryngeal cancer in several reports. However, the importance of comorbidity in hypopharyngeal cancer (HPC) has not been reported.
  Methods. A retrospective medical record review of 156 patients with HPC treated between 1995 and 2005 was performed. Comorbid illness was measured by the Adult Comorbidity Evaluation-27. A Cox proportional hazards model was used to determine the factors related to overall survival.
  Results. Comorbidity was absent in 55 (35.2%) of the patients, mild in 39 (25%), moderate in 28 (17.9%), and severe in 34 (21.8%). There were statistically significant differences between the survival rates in accord with age, stage, subsite, and comorbidity (45.1% for none or mild vs 27.7% for moderate or severe; p = .0073). Age, stage, and comorbidity were identified as independent prognostic factors in the multivariate analysis.
  Conclusion. Comorbidity, along with the clinical stage, should be considered in treatment planning for patients with HPC. (C) 2009 Wiley Periodicals, Inc. Head Neck 32: 148-153, 2010

  日本語, 研究論文（学術雑誌）, 目的:化学放射線療法後の喉頭癌再発例に対する喉頭全摘出術においては、咽頭皮膚瘻孔など創合併症に発生率が高いことが報告されている。その予防策として、咽頭粘膜縫合部を血流に富む新鮮な組織で覆う方法(pharyngeal interposition graft)の有用性が報告されている。今回、喉頭癌に対する化学放射線療法後の再発例において、喉頭全摘出術とともに大胸筋弁をpharyngeal interposition graftとして用いた4症例の術後経過について検討した。対象:化学放射線療法後に再発を来した喉頭癌4症例(声門上癌3例、声門癌1例)を対象とした。喉頭全摘出術後、咽頭粘膜を一次縫合し、さらに咽頭粘膜縫合部と挙上した皮膚の間に大胸筋弁を挟みpharyngeal interposition graftとした。結果:4例中3症例に軽度創合併症が生じた。気管孔周囲の局所感染、皮下小膿瘍、皮膚縫合部の表層壊死が各1例であり、いずれも局所処置で改善した。4症例ともに咽頭皮膚瘻孔などの重度創合併症は来さなかった。また、大胸筋弁の血流不全および採取に伴う合併症は認められなかった。結論:大胸筋弁を用いたpharyngeal interposition graftは安全であり、化学放射線療法後の喉頭全摘出術において咽頭皮膚瘻孔などの重度創合併症の発生を抑えるため有用であると考えられた。(著者抄録)

  日本語, 研究論文（学術雑誌）, There is an increased risk of wound complications in patients undergoing salvage laryngectomy following chemoradiotherapy. To reduce the rate of wound complications after a salvage total laryngectomy, a fresh tissue reinforcement of the pharyngeal suture line (pharyngeal interposition graft) has been reported to be useful. In the present study, wound complications after a salvage total laryngectomy with a pectoralis major muscle flap as a pharyngeal interposition graft were analyzed. Four patients with recurrent laryngeal cancer (three with supraglottis and one with glottic cancer) after chemoradiotherapy underwent salvage total laryngectomy using a pectoralis major muscle interposition flap. Minor wound complications were observed in three of the four patients, with an infection around the tracheostoma, a minor subcutaneous abscess, and a superficial skin necrosis in one patient each. These complications were managed with local wound care. No patients had major wound complications such as pharyngocutaneous fistulas. There were no necroses or wound complications of the pectoralis major muscle flap. This study has suggested that the pectoralis major muscle flap as a pharyngeal interposition graft is safe and useful for prevention of wound complications in salvage total laryngectomy following chemoradiotherapy.

  英語, 研究論文（学術雑誌）, BACKGROUND: The current study aimed to evaluate the efficacy of superselective high-dose cisplatin infusion with concomitant radiotherapy (RADPLAT) for previously untreated patients with advanced cancer of the nasal cavity and paranasal sinuses. METHODS: Between October 1999 and December 2006, 47 patients were given superselective intra-arterial infusions of cisplatin (100-120 mg/m(2) per week) with simultaneous intravenous infusions of thiosulfate to neutralize cisplatin toxicity and conventional external-beam radiotherapy (65-70 grays), RESULTS: There were 7 patients (14.9%) diagnosed with T3, 22 (46.8%) with T4a, and 18 (38.3%) with T4b disease. During the median follow-up period of 4.6 years, the 5-year local progression-free survival rate was 78.4% for all patients (n=47), 69.0% for patients with T4b disease (n=18), and 83.2% for patients with <T4b disease (n=29). The 5-year overall survival rate was 69.3% for all patients, 61.1% for patients with T4b disease, and 71.1% for patients with < T4b disease. RADPLAT was feasible in 45 patients (95.7%). No patient died as a result of treatment toxicity or had a cerebrovascular accident. Osteonecrosis (n=7), brain necrosis (n=2), and ocular/visual problems (n=16) were observed as late adverse reactions. CONCLUSIONS: Although a single institution experience, the results of the current study suggest that RADPLAT can cure the majority of patients with advanced cancer of the nasal cavity and paranasal sinuses, as well as preserve organs. Late adverse reactions should be monitored in future studies. Cancer 2009;115:4705-14. (C) 2009 American Cancer Society.

  英語, 研究論文（学術雑誌）, Purpose. The aim of this study was to determine if the standardized uptake value (SUV) of fluorodeoxyglucose positron emission tomography (FDG-PET) for head and neck cancer can predict the outcome of radiotherapy and if the SUV is correlated with histological grade, mitosis, and apoptosis.
  Materials and methods. The study included 45 head and neck cancer patients who underwent FDG-PET scanning before radiotherapy. The maximum SUV (SUVmax) of their primary lesions were measured. Biopsy was performed in all patients to determine the histological diagnosis. Altogether, 14 biopsy specimens were available for mitotic and apoptotic cell counts.
  Results. The mean SUVmax of T3 tumors was significantly higher than that of T1 (P = 0.01) and T2 (P = 0.011) tumors. The mean SUVmax of stage II disease was significantly lower than that of stage III (P = 0.028) and stage IV (P = 0.007) disease. There was a tendency toward a better locoregional control rate and disease-free survival for the lower SUV group using a cutoff value of 5.5. For 41 patients with squamous cell carcinoma or undifferentiated carcinoma, SUVmax did not reflect the histological grade. There was no correlation between the SUVmax and the mitotic/apoptotic status.
  Conclusion. SUVmax may correlate with the T classification and stage, but there was no predictive value for outcome of radiation therapy. Neither histological grading nor mitotic/apoptotic status is correlated with SUVmax.

  日本語, 大量シスプラチンの超選択的動注療法を、照射との同時併用療法(IA-CRT、新鮮例136例に対して)、術前治療(18例)、再発例への救済治療(11例)として行った。その結果、術前治療、再発例への効果は乏しく、新鮮例に対して照射と併用で行うのが有用であった。特に鼻副鼻腔と中咽頭前壁で良い結果が得られた。喉頭癌でも良好な喉頭温存が得られている。下咽頭については、局所制御率は良好だが、生存率向上には結びついていない。当科の経験では、IA-CRTの良い適応は、上顎洞癌、舌根癌と考えられた。IA-CRTは動注のメリットを生かせる症例にアンギオCTなどを利用した精度の高い確実な動注を行うことが重要である。(著者抄録)

  英語, 研究論文（学術雑誌）, Objectives: To evaluate the risk factors for perioperative complications among patients undergoing craniofacial resection for the treatment of skull base tumors. Design: Retrospective analysis. Participants: The study group comprised 29 patients with skull base tumors (22 malignant and 7 benign) who underwent 30 craniofacial resections at Hokkaido University Hospital between 1989 and 2006. Of these cases, 21 had undergone prior treatment by radiation (16 cases), surgery (7 cases), or chemotherapy (1 case). Moreover, 19 needed extended resection involving the dura (11 cases), brain (5 cases), orbit (12 cases), hard palate (5 cases), skin (3 cases), or cavernous sinus (2 cases). Main outcome measures: Perioperative complications and risk factor associated with their incidence. Results: Perioperative complications occurred in 12 patients (40%; 13 cases). There was a significant difference between complication rates for cases with and without prior therapy (52.4% vs. 11.1%). The complication rate for dural resection cases was 81.8%. There was a significant difference between complication rates for cases with and without dura resection. No postoperative mortality was reported. Conclusions: Craniofacial resection is a safe and effective treatment for skull base tumors. However, additional care is required in patients with extended resection (especially dural) and those who have undergone prior therapy.

  英語, 研究論文（学術雑誌）, Background: The current study aimed to evaluate the significance of an immunohistochemical assessment of tumor suppressor p53 as a prognostic marker in head and neck squamous cell carcinoma (HNSCC) patients treated with docetaxel and radiotherapy.
  Methods: The expression of tumor suppressor p53 and its phosphorylated form at the Ser392 residue was retrospectively evaluated by immunohistochemistry in 51 Stage T1-3N0-2M0 (except T1N0 glottis) HNSCC patients who were treated with 10 mg/m(2)/Week docetaxel four to six times and received concurrent chemoradiotherapy.
  Results: Kaplan-Meier univariate analysis revealed that no difference in rates for overall and disease-free survival (DFS) between patients with p53-positive and -negative tumors (p = 0.786 and p = 0.924, respectively). The prognostic significance of phosphorylated p53 at the Ser392 residue was neither observed.
  Conclusions: An immunohistochemical assessment of the expression of p53 and its phosphorylated form might not be of clinical use in defining subgroups of patients with poor prognosis. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

  日本語, 研究論文（学術雑誌）, 頭頸部癌における機能温存療法として化学療法同時併用放射線療法(CCRT)が普及してきた。しかし、CCRT後の救済手術においては合併症の発生率が高いことが報告されており、慎重な対応を要する。当科では1995年から2008年5月の間に、喉頭癌131例、下咽頭癌107例に対して根治的CCRTを施行した。喉頭癌では131例中43例(33%)に原発再発を認め、うち38例(88%)に救済手術を施行し、30例(79%)に局所制御が得られた。一方、下咽頭癌では107例中30例(28%)に原発再発を認め、うち10例(33%)に救済手術を施行し、6例(60%)に局所制御が得られた。また、当科で救済手術として喉頭全摘または咽喉食摘術を施行した34例(喉頭癌28、下咽頭癌6)において術後合併症を検討したところ、軽症を含むすべての局所合併症は53%、重度局所合併症は29%、咽頭皮膚瘻は26%に認められた。CCRT症例では高度の組織障害による創傷治癒機転の障害のため、救済手術後に感染や瘻孔などの合併症を生じやすい。我々は合併症の予防対策として皮膚切開線の工夫、前頸筋や甲状腺の保存、主要静脈の保存などによる組織血流の保存や死腔防止に努める他、喉頭全摘後の咽頭粘膜縫合部と皮膚の間に大胸筋弁を挟む方法(pharyngeal interposition graft)を行なっている。CCRT開始前には救済手術時の高い合併症発生率と創傷治癒が不良であることを考慮した上で適応を判断するべきであり、救済手術においては、合併症を防止するための対策が重要であると考えられた。(著者抄録)

  英語, 研究論文（学術雑誌）, Purpose: To find a new molecule that affects p53-dependent radiosensitivity.Methods and Materials: A mouse sarcoma cell line, QRsP(p53+/+), was used. From this cell line, we established a radiosensitive clone and a radioresistant one. Colony assay, p53 gene transfer, a luciferase assay for p53 and p21, animal transplantation experiment, and DNA array analyses were performed.Results: Microarray showed marked reduction of a transcription factor, ATF5, both in vitro and in vivo for the radiosensitive clone. Interestingly, flow cytometric analysis demonstrated marked apoptosis for the radiosensitive clone by p53 cloned adenovirus infection. Luciferase reporter assay revealed that ATF5 suppressed the transactivational activity of p53 and p63. By ATF5 gene transfer, the radiosensitive clone regained resistance to both ionizing-radiation and Ad-p53 infection-induced cell death. Surprisingly, time-lapse cell migration observation revealed greater cell motility for ATF5-transfected radiosensitive clone.Conclusions: It seems likely that ATF5 is a potent repressor of p53 and elevated expression of ATF5 in a tumor may relate to enhanced malignant phenotypes, such as radioresistance or greater cell motility.

  英語, 研究論文（学術雑誌）, In total maxillectomy, the entire upper jaw including the tumor is removed en bloc from the facial skeleton. An intraoperative computed tomographic guidance system (ICTGS) can improve orientation during surgical procedures. However, its efficacy in head and neck surgery remains controversial. This study evaluated the use of an ICTGS in total maxillectomy. Five patients with maxillary sinus neoplasms underwent surgery using a StealthStation (R) ICTGS. The headset was used for anatomic registration during the preoperative CT scan and surgical procedure. The average accuracy was 0.95 mm. The ICTGS provided satisfactory accuracy until the end of resection in all cases, and helped the surgeon to confirm the anatomical location and decide upon the extent of removal in real time. It was particularly useful when the zygoma, maxillary frontal process, orbital floor, and pterygoid process were divided. All patients remained alive and disease free during short-term follow-up. The ICTGS played a supplementary role in total maxillectomy, helping the surgeon to recognize target points accurately in real time, to determine the minimum accurate bone-resection line, and to use the most direct route to reach the lesion. It could also reduce the extent of the skin incision and removal, thus maintaining oncological safety.

  英語, 研究論文（学術雑誌）, Surgical complication rates of total laryngectomy vary according to the preoperative treatments performed and patient factors. Wound complications after salvage laryngectomy following concurrent chemoradiotherapy (CCRT) were analyzed.
  Eighty-six patients who had undergone total laryngectomy for laryngeal cancer at Hokkaido University Hospital, Japan, between 1990 and 2006 were divided into three groups according to preoperative treatments received: group I (n = 35) without radiotherapy (RT) or CCRT, group II (n = 17) RT alone, and group III (n = 34) low-dose CCRT. Salvage total laryngectomy was performed as a consequence of residual or recurrent disease after completion of the treatments. Wound complications such as pharyngocutaneous fistulas, bleeding, infections, and skin necrosis were retrospectively analyzed in each group.
  A considerable (not statistically significant) difference in the incidence of major wound complications was observed between groups I and III (11.4% vs 29.4%, P = 0.078), but not between groups II and III. In stage III/IV patients, a significant increase in the incidence of wound complications was observed in group III compared to group I. Pharyngocutaneous fistulas were the most common complication, occurring in 8/34 (23.5%) of the group III patients. Additional pharyngeal reconstruction surgery was performed in 5 of the 8 (62.5%) group III patients with pha ryngocutaneous fistulas, while no such patients (0/3) in group I required reconstruction surgery.
  There was an increased risk of wound complications in patients undergoing salvage laryngectomy following CCRT. Patients who developed pharyngocutaneous fistulas after CCRT tended to require surgical reintervention for repair. These findings should be taken into account before the initiation of CCRT and salvage surgery.

  日本語, 喉頭癌の化学放射線療法(chemoradiotherapy;CRT)後の再発症例において、salvage手術法の選択について検討した。1995年-2001年のCBDCAまたはCDDP併用CRT後の再発例においては23例全例で喉頭全摘術が施行された。2002年-2005年のDOC併用CRT後の再発例においては喉頭機能温存手術が4例に、喉頭全摘術が6例に施行された。症例を選択すれば喉頭機能温存手術は可能であると考えられた。CRT後においては2年以上経過してからの再発例も多くみられ、喉頭機能温存手術を施行するためには、2年以上経過しても画像検査を含め、経過観察を慎重に行うべきであると考えられた。喉頭全摘術を余儀なくされた場合でも、人工喉頭挿入によるTEシャント発声によりquality of life(QOL)の向上を図ることができた。また、いずれのsalvage手術においても術後の創合併症の発生率が高く、創合併症に対する適切な対処が重要であると考えられた。(著者抄録)

  日本語, 4列から始まったCTの多列化の波は、現在320列まで進化し、臨床に多大なインパクトを与えている。64列CTの普及により、冠動脈CTが侵襲性の高い心臓血管造影検査に取って代わりつつある。撮影時間の短縮化、等方向性のボリュームデータの収集による恩恵によるものであるが、膨大な情報量を処理するコンピュータの発達もあり、モニタ上で診断することが日常化してきている。従来、心臓血管造影検査がゴールドスタンダードとされてきたが、最近のCore64の報告で、あらゆる人種の冠動脈疾患の診断において、64列MDCTは心臓カテーテル検査(CAG)に匹敵、あるいは凌駕するとしている。64列MDCTでは、息止め時間が約10秒以下で撮影できるようになり、モーションアーチファクトの少ない画像が得られるようになった点が大きな理由と思われる。MIP,curved MPR(multiplanar reformation),VR(volume rendering)などの多彩な表示機能により、血管内腔が静止画像で多角的にとらえられるようになり、血管の内腔の評価やプラークの性状についても詳細な検討ができるようになった点も大きな利点と言える。当院では、2005年9月の開院当初より64列MDCTを導入し、574例の冠動脈造影CTをルーチンで施行してきたが、従来の報告と同様の診断能が得られている。本稿では、当院における撮影プロトコールを紹介し、臨床例を提示しながら臨床面における利点、問題点などについて述べる。(著者抄録)

  英語, 研究論文（学術雑誌）, Detecting the risk factors for late neck metastasis (LNM) in early tongue and oral floor cancer is important for establishing an accurate prognosis, as well as for increasing survival rates. Patients with either stage I or II tongue and oral floor cancer underwent either a resection of the primary tumor or interstitial radiotherapy without neck dissection. We measured the short- and long-axis diameters of lymph nodes on initial CT images. Of the 38 patients, 20 had LNM and 18 did not. CT images showed a total of 161 lymph nodes. Twenty-five "occult lymph nodes" developed into LNM, whereas the remaining 136 "reactive lymph nodes" did not. Comparison between "occult" and "reactive" lymph nodes revealed significant differences in the short-axis diameters (p = 0.01). The measure of short-axis diameters of neck lymph nodes on initial, CT images is a useful predictor of LNM in patients with early tongue and oral floor cancer. (c) 2007 Elsevier Ltd.

  日本語, 研究論文（学術雑誌）, 頸動脈小体腫瘍は、頸動脈分岐部に発生する比較的まれな腫瘍であり、手術においては出血のコントロールおよび術後神経障害が問題となる。それゆえ、術前の栄養血管塞栓術が有用と報告されている。今回、頸動脈小体腫瘍手術症例において、術前栄養血管塞栓術の有効性および術後合併症の検討を行ったので報告する。1990年から2005年までに、当科にて頸動脈小体腫瘍と診断され手術を施行した6例7側を対象とした。術前診断としてCT,MRI、超音波検査、血管造影検査を行った。4例5側に術前栄養血管塞栓術を施行した。栄養血管塞栓術施行4例5側では、術中出血量が平均291mlで、手術時間が平均4時間55分であった。非施行2例では、術中出血量が平均1016mlで、手術時間が平均10時間17分であった。脳神経障害を認めた例は一過性も含めると、舌咽神経麻痺1例、迷走神経麻痺2例、舌下神経麻痺4例5側であった。栄養血管塞栓術施行例では、術後脳神経障害が出現しても一過性であり、短期間で改善する傾向がみられた。両側切除例においてbaroreflex failure syndromeを認めた。栄養血管塞栓術施行例では、非施行例と比較して術中出血量が少なくなり、手術時間が短縮する傾向が見られた。また、術後脳神経障害の程度が軽度であった。(著者抄録)

  英語, 研究論文（学術雑誌）, Background. The current study aimed to evaluate the significance of the cell-cycle-control proteins cyclin D1 and p16 as prognostic markers in head and neck squamous cell carcinoma (HNSCC) patients treated with docetaxel and radiotherapy.
  Methods. Cyclin D1 and/or p16 protein expression was retrospectively evaluated by immunohistochemistry in 53 patients with stage T1-3N0-2M0 (except T1NO glottis) HNSCC who were treated with 10 mg/m(2)/week docetaxel 4 to 6 times and received concurrent chemoradiotherapy.
  Results. Kaplan-Meier univariate analysis revealed that patients with cyclin D1-positive tumors or p16-negative tumors had a worse prognosis compared with those with cyclin D1-negative tumors or p16-positive tumors (p =.0004 and p =.025, respectively). The prognostic significance of cyclin D1 expression, not p16 expression, was confirmed using a proportional hazard regression model.
  Conclusions. An assessment of cyclin D1 and p16 levels might be of clinical use in defining subgroups of patients with poor prognosis. (c) 2007 Wiley Periodicals, Inc.

  英語, 研究論文（学術雑誌）, Radiation detectors were fabricated using single and polycrystalline cubic boron nitride (cBN) crystals synthesized using a high-pressure and high-temperature (HP/HT) method. Although cBN single crystals obtained using a barium BN solvent system were nearly colorless and displayed high electrical resistance, in contrast to conventional amber-colored crystals, the single crystals exhibit a leakage current that renders them unsuitable for use in a detector. In contrast, a detector made of a cBN polycrystal synthesized by direct transformation had a very low leakage current of 0.2pA with bias voltage of 100V; it functioned as a radiation detector. From an experiment using alpha-particles, holes traversed a longer distance than electrons. It had a fast rise time of approximately 300ns. The detector also showed sensitivity to neutrons. However, output signals were smaller than the expected voltage from the experiment using alpha-particles, probably because of charge accumulation from the high-neutron flux. (C) 2007 Elsevier B.V.

  英語, 研究論文（学術雑誌）, 化学放射線併用療法(CRT)後のsalvage手術においては合併症の発生率が高いことが報告されており、慎重な対応を要する。北海道大学病院にて化学放射線同時併用療法(CCRT)を施行後、残存・再発によりsalvage手術を行った喉頭癌症例を対象として、術後の合併症を検討した。1990年から2006年まで当施設で喉頭全摘術を施行された喉頭癌症例86例を3群に分け検討した。すなわち初回治療として喉頭全摘術が施行されたTL群35例、根治照射後に喉頭全摘術が施行されたRT-TL群17例、CCRT後に喉頭全摘術が施行されたCRT-TL群34例である。術後8週以上の入院または再建手術を要した喉頭皮膚瘻、再手術を要した出血、術後8週以上の入院を要した感染・皮膚壊死を重度合併症と定義した。短期間の局所創処置で対処可能であった気管壁壊死、創感染、咽頭皮膚瘻、リンパ漏を軽度局所合併症とした。CCRT後に喉頭機能温存手術を施行した症例についても合併症を検討した。重度、軽度局所合併症を合わせた全局所合併症発生率はTL群において26%、RT-TL群35%、CRT-TL群47%であった。重度局所合併症発生率はTL群11%、RT-TL群18%、CRT-TL群29%であった。全局所合併症、重度局所合併症についてTL群とCRT-TL群で比較すると有意差はみられないが発生率が高まる傾向が認められた(p=0.082と0.078)。咽頭皮膚瘻は16%に発生した。CCRT後に咽頭皮膚瘻が生じた場合、再建術を要する重度咽頭皮膚瘻が多く、また経口摂取まで長期間を要する傾向がみられた。CCRT後の喉頭機能温存手術においても3例中2例(67%)で創合併症が生じた。CRT開始前にはsalvage手術時の高い合併症発生率と創傷治癒が不良であることを考慮に入れ適応を選択するべきであると考えられた。(著者抄録)

  英語, 研究論文（学術雑誌）, Objective: This study sought to evaluate the efficacy and safety of a novel treatment regimen, intra-arterial cisplatin infusion plus external/high-dose-rate radiotherapy.
  Methods: Superselective intra-arterial infusion of cisplatin (100-120 mg) was performed concomitantly with external radiotherapy in four patients with locally advanced carcinoma of the tongue. A high-dose-rate brachytherapy boost was performed after combination therapy in all patients. Brachytherapy was performed after external radiotherapy, and the treatment schedule was twice daily, with a fraction of 600 cGy up to a total of 30-48 Gy.
  Results: All patients completed the therapy as scheduled. There were no vascular or neurological complications. Grade III acute radiation mucositis developed in all patients but this did not necessitate a treatment break. With a mean follow-up period of 35 months, loco-regional control was obtained for all patients.
  Conclusions: The combination of weekly administration of intra-arterial cisplatin plus external/high-dose-rate radiotherapy seems effective for advanced carcinoma of the tongue.

  英語, 研究論文（学術雑誌）, Background. Chemoradiotherapy (CRT) is becoming more widely used for head and neck cancer. However, there are conflicting theories regarding the best management options for patients with advanced nodal disease. Methods. From 1990 to 1999, we treated 96 patients with N1-N2 neck disease by concomitant CRT for organ preservation, using weekly carboplatin or a low daily dose of cisplatin, followed by a "watch-and-see" policy for the neck. In the present study, we retrospectively analyzed the treatment outcome in 63 of these patients who received definitive CRT for primary and neck diseases and were monitored for neck disease for more than 2 years. Results. In 12 of the 22 (55%) N1 patients, CRT successfully controlled the neck disease. CRT was successful in 18 of the 41 (44%) patients with N2 disease. In 6 (60%) of 10 patients with residual or recurrent N1 disease, salvage surgery was successful. Of the 23 patients with residual or recurrent N2 disease, salvage surgery was successful in 8 patients (35%). The group of patients who showed a clinical complete response (CCR) to CRT had an overall survival rate of 62.4% (33 patients), whereas for those with a less than complete response (<
  CCR), the figure was 13.3% (30 patients
  P <
  0.001). Among the <
  CCR-neck group, patients who underwent neck dissection (ND) as well (n = 20) did not have a significantly better overall survival than those who did not undergo ND (n = 10
  P = 0.069). Conclusion. We propose a treatment plan for neck disease that involves observing the neck closely following CRT. ND should be planned only when there is evidence that neck disease exists. © 2006 The Japan Society of Clinical Oncology.

  日本語, 近年上咽頭癌放射線治療後晩期に嚥下障害を来した例を3例経験した。症例は男性2例女性1例で、治療時年齢は20-41歳。2例は上咽頭癌に対する標準的な放射線治療を、1例は放射線化学併用療法を受けており、治療後8-15年で嚥下障害を発症した。全例両側舌下神経麻痺を中心として咽喉頭の感覚運動障害を有し、1例では補助栄養として間欠的口腔食道栄養法(OE法)を指導し、1例では誤嚥性肺炎をコントロールするため誤嚥防止手術(喉摘)を必要とした。末梢神経線維は一般に放射線抵抗性とされるが、過去の報告では放射線障害による脳神経障害に起因した誤嚥性肺炎で死亡する例も存在する。近年上咽頭癌に対し放射線化学併用療法が積極的に行われており、予後の改善と引き換えに晩期脳神経障害を背景にした嚥下障害が増加する可能性があることを、嚥下障害を担当する医療者や頭頸部腫瘍治療担当者は銘記する必要があろう。(著者抄録)

  日本語, 症例は59歳女性で、右上顎洞原発扁平上皮癌(T3M0N0)と診断された。MRI上腫瘍は右上顎洞内上方を中心に存在し篩骨洞にも進展を認め、CTでは眼窩内側壁の骨破壊を認めた。40Gyの術前照射後にナビゲーションシステムを用いて上顎洞全摘出術を施行した。ナビゲーションシステムは解剖学的位置をリアルタイムに確認しながら骨切り線を決めることができるので有用であり、本症例では特に頬骨・上内側の前頭突起・眼窩下壁の切除ラインの設定、翼状突起にノミを入れる際の位置と方向の決定に有用であった。以上よりナビゲーションシステムは上顎洞全摘術の施行に際して必要な三次元的な解剖の理解と腫瘍の局在に合わせた切除範囲の設定に補助的な役割を果すものとして有用性が高く、また安全性を確保して上で切除範囲を縮小できる可能性もあると考えられた。

  日本語, 今回我々は頬粘膜に生じ、術前動注化学療法を施行した有棘細胞癌の1例を経験した。患者は66歳男性、初診の1年半前より右頬粘膜に腫瘍を自覚し、近医での生検にて有棘細胞癌の診断に至った。当科初診時、右頬粘膜から口角に径3.5cmの腫瘍を認め、全身精査の結果転移を認めず、T2N0M0 Stage IIと診断した。根治性とQuality of lifeを考慮し、術前動注化学療法と手術療法併用による治療を行った。Cisplatin 100mg/m2による超選択的動注療法により腫瘍は著明な縮小を認め、侵襲の少ない手術を施行出来た。超選択的動注化学療法は従来、主に手術不能例に対して放射線照射との同時併用で施行されているが、手術可能でかつ再建が困難な症例に対して患者のQuality of lifeを考慮する縮小手術の点から、術前療法としても期待出来ると考えた。(著者抄録)

  日本語, 超選択的動注療法と放射線同時併用療法を行なった下咽頭進行癌15例について検討した.現在までの治療経過は非担癌生存11例,原病死3例,他病死1例であった.予後はKaplan-Meier法で検討し,2年粗生存率が53.7%,喉頭温存率が78.3%であった.今回の治療は,シスプラチンの経静脈的全身投与による放射線同時化学療法と比較して有害事象が遜色なく,治療後のQOLも許容範囲内であった.また,超選択的動注を行なう際はSeldinger法が望ましく,アンギオCTにより腫瘍への血流分布を確認するのが望ましいと考えた(著者抄録)

  日本語, 研究論文（学術雑誌）, Olfactory neuroblastoma is an uncommon intranasal tumor originating from olfactory neuroepithelium. Despite the development of electron microscopy and immunohistochemical testing, the pathological diagnosis of this tumor is still difficult because of the wide range of histological features. Magnetic resonance imaging (MR) of this tumor and the pattern of contrast enhancement have not been well described. The purpose of this report was to analyze the MR characteristics of olfactory neuroblastomas. The MR signal, pattern of contrast enhancement, and correlation with high-resolution computed tomography (CT) imaging were examined. Seventeen patients with olfactory neuroblastoma were treated at Hokkaido University Hospital and a related hospital during the past 25 years. MR images taken in 12 patients and CT images taken in 9 patients with histologically confirmed olfactory neuroblastoma were retrospectively reviewed. Compared with brain gray matter, 11 tumors were hypointense on T1-weighted images, 9 homogeneously and 2 heterogenously. Eight tumors were hyperintense on T2-weighted images, 3 homogeneously and 5 heterogeneously, although their appearance was less intense than that of sinusitis. Gadolinium enhancement was moderate in one case and marked in 10 of the 11 cases, 9 homogeneously and 2 heterogeneously. Nine of the 11 tumors showed smooth regular shaped margins
  2 of these tumors exhibited irregular infiltrating margins on gadolinium-enhanced images, compared to the pre-contrast T1-weighted images. Eight of the 11 tumors had clearly demarcated margins, while 3 of the 11 tumors did not exhibit gadolinium enhancement. Six of the 12 cases (50%) exhibited intracranial cysts on the gadolinium-enhanced images. T2-weighted or gadolinium-enhanced images successfully distinguished sinusitis from tumors in 4 cases whereas the CT images failed. Gadolinium enhancement, particularly in the tangential plane, demonstrated intracranial extension not apparent on the CT images in one case. In most cases, olfactory neuroblastomas are hypointense on T1-weighted images, hyperintense on T2-weighted images, and show marked homogeneous enhancement with well-demarcated regular margins upon gadolinium enhancement. Although the definite diagnosis is based on histopathology findings and MR features are nonspecific, they may suggest an imaging diagnosis of olfactory neuroblastoma when seen in the superior nasal cavity. MR is superior to CT both in delineating the extent of the tumor and in making an imaging diagnosis.

  日本語, 研究論文（学術雑誌）, Olfactory neuroblastoma is such a rare malignancy that no consensus has been reached on its management. We analyzed 17 patients with olfactory neuroblastoma treated between April 1980 and March 2004-9 men and 8 women, aged 16 to 76 years old (mean: 50.4 years). Follow-up of current survivors vas 1 year 8 months to 16 years 6 months (average: 7 years 9 months). Initially, 2 were treated with surgery alone, 5 with surgery and radiotherapy, and 2 with a combination of these and chemotherapy. Without surgery, radiotherapy alone was conducted in 3 and combined of radiation and chemotherapy in 5. Three of the 5 patients treated with surgery and radiotherapy survive without locoregional recurrence as do 2 with chemotherapy added. All 5 initially treated with craniofacial resection survived more than 5 years. Combined radiotherapy and chemotherapy without surgery was effective in 2. 5- and 10-year overall survival for all patients were 75.5% and 64.7%. Overall 5-year survival of 8 patients with low-grade tumors was 87.5% and of 6 with high-grade tumors 33.3%. In conclusion, combined craniofacial resection plus radiotherapy and chemotherapy seemed to improve survival. Histopathological grading is a prognostic factors.

  英語, 研究論文（学術雑誌）, The purpose of this study was to discover whether S100A2 expression is associated with late cervical metastasis in patients with stage I and II invasive squamous cell carcinoma of the oral cavity. We retrospectively investigated the clinicopathological parameters and S100A2 expression in surgical specimens taken from 52 patients with T1-2N0M0 invasive squamous cell carcinoma of the oral cavity (OSCC) who had not undergone elective neck dissection or irradiation to the neck. All of the clinic opathological factors and S100A2 expression were compared in terms of late cervical metastasis. In univariate analysis, late cervical metastasis correlated with poor overall survival. A higher rate of late cervical metastasis was observed in patients with S100A2-negative tumors than those with S100A2-positive tumors. Multivariate analysis on late cervical metastasis revealed that S100A2 expression was demonstrated to be the only independent factor for late cervical metastasis. Our results indicate that patients with stage I or 11 invasive OSCC without SIOOA2 expression should be considered a high-risk group for late cervical metastasis when a wait-and-see policy for the neck is being considered.

  英語, 研究論文（学術雑誌）, Background: Voice restoration after circumferential pharyngolaryngectomy (CPL) with free jejunal graft remains a difficult problem to solve. Few reports have analyzed the success rate and complications following primary insertion of indwelling voice prostheses during CPL with free jejunal graft.
  Patients and methods: Eight patients who underwent CPL with free jejunal graft had a Groningen voice prosthesis inserted as a tracheoesophageal (TE) shunt at the time of oncological surgery. A 10-point scale was used to assess each patient's speech intelligibility. Complications following the voice prosthesis insertion were also analyzed.
  Results: Six of the eight patients (75%) achieved excellent speech intelligibility and the remaining two patients (25%) were judged as moderate. Six of the eight patients (75%) used the TE shunt as their major means of daily communication. Leakage through or around the prosthesis, which occurred in six (75%) patients, was the most frequent prosthesis-related complication.
  Conclusions: This safe and reliable technique can be effective in improving the quality of life in selected patients undergoing CPL. (c) 2005 Elsevier Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, The macrophage migration inhibitory factor (MIF) is known to be a proinflammatory cytokine as well as a tumor growth regulator. Although the positive and negative effects of the MIF on tumor cell growth have been reported, the exact role of the MIF in tumorigenesis remains ambiguous. We examined the expression of the MIF protein in tumor specimens obtained from 50 head and neck squamous cell carcinoma (HNSCC) patients treated with concurrent chemoradiotherapy (carboplatin, 100 mg/m2), 4-7 times every week; a total radiation therapy dose of 65-75 Gy over 6.5-7.5 weeks, and determined whether the MIF level is related to clinical outcomes of these patients. Immunostaining with an MIF specific antibody was performed in formalin-fixed, paraffin-embedded specimens. The MIF protein was expressed to various extent in the tumor tissue specimens from the HNSCC patients. Prognostic analysis using the Kaplan-Meier method with regard to the MIF expression revealed that the patients with the MIF-negative tumors had a worse prognosis when compared to those with the MIF expression. The results of this study suggest that the intratumoral MIF expression has a prognostic value in HNSCC patients administered concurrent chemoradiotherapy.

  英語, 研究論文（学術雑誌）, Purpose. The purpose of this study was to evaluate the efficacy of rapid superselective high-dose cisplatin infusion with concomitant radiotherapy for previously untreated patients with advanced head and neck cancer. Methods. Forty-three patients for whom surgery was contraindicated or who rejected radical surgery were given superselective intra-arterial infusions of cisplatin (100-120 mg/m(2)/week) with simultaneous intravenous infusion of thiosulfate to neutralize cisplatin toxicity and conventional extra-beam radiotherapy (65 Gy/26 f/6.5 weeks). Results. Thirty-nine patients had stage IV disease, and the remaining four had stage III disease. During the median follow-up period of 21 months, the 3-year locoregional progression-free rates of all patients (n = 43) and patients with unresectable disease (n = 24) were 68.9% and 56.4%, respectively. In addition, the 3-year overall survival of all patients and patients with unresectable disease was 54.0% and 39.6%, respectively. Thirty-five patients (81.4%) experienced nonhematologic grade III to Iv toxicity, including mucositis (n = 16), nausea/vomiting (n = 8), and neurologic signs (n = 2). No patient died as a result of treatment toxicity. There are 29 surviving patients without evidence of disease, all of whom are able to have oral intakes without feeding-tube support.
  Conclusions. We confirmed the efficacy of superselectives arterial infusion and concomitant radiotherapy, which can concentrate the attack of supradosa cisplatin on locoregional disease. Even patients with unresectable disease can be cured. Further studies are needed to establish the indications, long-term outcome, and possible side effects of this treatment.

  英語, 研究論文（学術雑誌）, Purpose
  This randomized, phase II study aimed to compare concomitant chemoradiotherapy using weekly carboplatin or daily low-dose cisplatin as a treatment for squamous cell carcinoma of the head and neck.
  Patients and Methods
  One hundred nineteen patients with moderate- to advanced-stage disease were eligible for the study. Fifty-three patients had stage II disease, 28 had stage III, and the remaining 38 had stage IV disease. Primary tumor sites included the larynx (N = 63), oropharynx (N = 30), hypopharynx (N = 23), and oral cavity (N = 3). Each patient received either a weekly carboplatin dose (100 mg/m(2)) in one arm or daily cisplatin (4 mg/m(2)) in the other arm for the initial 4 weeks of radiotherapy. The radiotherapy dose of 65 Gy was given in 26 fractions over 45 days, dependent on a good tumor response at 40 Gy. Forty-nine (81.7%) of 60 patients treated with carboplatin and 41 (69.5%) of 59 patients treated with cisplatin received the full dose of radiotherapy. Surgical resection was optionally used for the remaining patients.
  Results
  The median follow-up time was 63 months. The local control rate at 5 years was 56.2% for the carboplatin-treated arm and 35.5% for the cisplatin-treated arm, respectively. The 5-year overall survival rate did not significantly differ between treatments: 71.4% for carboplatin and 66.0% for cisplatin. Hematologic toxicity was more frequent in the carboplatin-treated arm. No difference was observed in surgical complications or in radiation-related adverse effects.
  Dicussion
  These findings suggest that weekly carboplatin treatment is preferable to daily low-dose cisplatin. This could be because the total dose of cisplatin was too low to be effective.

  英語, 研究論文（国際会議プロシーディングス）, A thin GSO scintillator was developed aiming at applications for the neutron science. In order to fabricate a large and thin GSO scintillator in the future, fabrication was started from two types of GSO powders. Although several GSO films were fabricated by evaporation techniques, these films did not have luminescence in photo luminescence (PL) spectroscopy. Thus, these samples were annealed up to 1550°C. However, it resulted in no luminescence observation. In response to these results, GSO powders were directly annealed
  a phenomenon looking like melting and sintering were observed for Gd2Si 2O7:Ce at a temperature higher than 1500°C. This sample was quasi-transparent and had luminescence at 405nm in PL spectrum. In addition, this sample was tougher than a GSO single crystal. In conclusion, the prospect of fabrication of a thin GSO scintillator by combination of annealing and mechanical polishing was obtained. © 2004 Elsevier B.V. All rights reserved.

  英語, 研究論文（学術雑誌）, Objectives/Hypothesis: Sinonasal inverted papilloma is a rare but locally aggressive benign tumor. Inverted papilloma tends to recur after surgical resection and is occasionally associated with squamous cell carcinoma. Radical en bloc resection by lateral rhinotomy and medial maxillectomy has been recommended for initial management; however, endoscopic sinus surgery is effective in selected cases. To determine adequate surgical approaches, a staging system for inverted papilloma based on extent and location of the tumor has been advocated. The study investigated whether preoperative assessment by magnetic resonance imaging (MRI) accurately predicts the extent of inverted papilloma. Study Design: Magnetic resonance imaging was retrospectively reviewed in 21 cases of inverted papilloma without knowledge of the surgical and pathological findings. Methods: Patients were categorized into stages based on MRI findings, according to the staging system proposed by Krouse. The involvement of inverted papilloma in each sinus was also assessed. Results: Stages graded by MRI were coincident with postoperative staging verified by surgical and pathological findings in 18 of the 21 cases (86%), which included 1 case of stage T1, 3 cases of stage T2, and 14 cases of stage T3. Two cases of stage T2 were judged as T3, and one case of T3 was judged as T2 by MRI. Positive predictive value of MRI diagnosis for tumor involvement was 68% to 89% in each sinus, and negative predictive value was more than 93%. Conclusion: In most cases, MRI assessment of inverted papilloma can accurately predict the extent of tumor involvement. Preoperative staging of inverted papilloma by MRI may be useful for planning an appropriate surgical approach.

  日本語, 研究論文（学術雑誌）, A 60-year-old man had a recurrence of squamous cell carcinoma at the right side of the tongue base. Chemotherapy with TS-1 (100 mg/day) was begun. Each course of chemotherapy consisted of 4 weeks of TS-1, followed by 2 weeks of no treatment. After the completion of two courses, macroscopic examination revealed a complete response. From the third course of TS-1 treatment, the dose was increased to 120 mg/day. The complete response persisted on macroscopic examination. A biopsy done during the ninth course of TS-1 treatment confirmed the complete response histologically, with no evidence of malignancy. After 12 courses of TS-1 treatment, the drug was switched to 600 mg/day of UFT. Although there were no signs or symptoms of recurrence, the patient died of cancer of the pancreas. There was no recurrence of the oropharyngeal cancer, even at the time of death.

  英語, 研究論文（学術雑誌）, Objective: To evaluate the efficacy and safety of concurrent carboplatin (CBDCA) and radiotherapy for laryngeal carcinoma, we investigated survival rates and laryngeal preservation rates in patients with this treatment modality and those with radiation therapy only. Methods: We underwent chemotherapy with CBDCA and conventional radiotherapy concurrently to 17 patients with untreated stage II (T2N0M0) supraglottic squamous cell carcinoma since November 1990. CBDCA (100 mg/m(2)) was administered intravenously once a week concurrently with radiotherapy (2.5 Gy/fr, 4 times a week). At the dose of 40 Gy, the results were evaluated, and some of the patients underwent planned surgery and others continued the radiotherapy up to 65 Gy. Results: Overall 5-year survival rate by Kaplan-Meier method was 81.1%. Actual laryngeal preservation rate was 76.0%. Toxicity over grade III was noticed in two patients. Compared with 14 cases of historical controls, which were treated by radiation therapy alone between 1988 and 1990, the cases with concurrent radiotherapy and chemotherapy had statistically significant advantage in overall successful laryngeal preservation rate (P < 0.05), whereas the two groups were not significantly different in the overall 5-year survival rate.

  英語, 研究論文（学術雑誌）, Objective: to improve the management of maxillary sinus carcinoma, we retrospectively investigated the significance of cervical lymph node metastasis in our treated cases and discussed how to deal with the cervical lymph node metastasis as a prognostic factor. Methods: medical records of 118 patients with maxillary sinus carcinoma diagnosed and treated in our institute from 1982 to 1997 were retrospectively reviewed. Tumors were staged according to UICC classification 1987. The cumulative survival was analyzed by the Kaplan-Meier method. Generally, the patients had undergone preoperative radiotherapy and surgery. We examined the cervical lymph node metastasis detected at the first examination and the subsequent cervical lymph node metastasis in relation to the prognoses. Results: the incidence of cervical lymph node metastasis at the initial diagnosis was 7.9% (n = 9), and that of secondary cervical lymph node metastasis without recurrence at the primary site after the first treatment was 8.3% (n = 9). In most cases, we observed metastasis to the lymph nodes in the submandibular region and in the jugular chain. The result of treatment of cervical lymph node metastasis was grave. Among the patients with cervical lymph node metastasis detected at the first examination, four patients developed local recurrence and three patients developed distant metastasis. On the other hand, among those with secondary cervical metastasis, three patients developed neck recurrence and three patients developed distant metastasis, but no local recurrence. Conclusions: in the cervical metastasis of maxillary sinus carcinoma, it is important to treat the primary lesion completely. In addition to it, we should control cervical metastasis and careful neck dissection is required. For the patients with cervical lymph node metastasis, it is necessary to consider the further treatment of distant metastasis. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.

  英語, 研究論文（学術雑誌）, Objective: We examined prognostic factors and outcome of the primary treatment in patients with adenoid cystic carcinoma (ACC) of the head and neck. Methods: Twenty patients with ACC of the head and neck who had been treated in our institution from 1985 to 1998 were enrolled in this study. Disease-specific survival rate was analyzed by the Kaplan-Mejer method, and the log-rank test was applied to compare the survival rates. Results: The overall 5- and 10-year survival rates determined by Kaplan-Meier analysis were 81 and 57%, respectively. Patients with major salivary gland ACC obtained the best 10-year survival rate (83%), while those with paranasal sinus ACC had the worst survival rate (33%). Predominance of the solid component on pathological examination might indicate a worse prognosis. Our study revealed that postoperative radiotherapy could yield better control of the lesion focus. Chemotherapy failed in some patients and was not dramatically effective by itself. Conclusions: The long-term prognosis of ACC was poor. Long-term follow-up is necessary for better prognosis of patients treated with radical treatment regimens. (C) 2001 Elsevier Science Ireland Ltd. All rights reserved.
• A study of piriform sinus fistula cases

  AURIS NASUS LARYNX, 28, S139, S143, ELSEVIER SCI LTD, 2001年05月
  英語, We have experienced five cases of piriform sinus fistula for the last 10 years. It is a relatively rare disease, and partly because of poor understanding of the disease, in one case infection had repeatedly recurred without being adequately treated for over 20 years, and in most cases there was a long time lapse before the diagnosis. In another case, it was difficult to image the fistula with contrast medium and fistulectomy was performed without identifying it on imaging. We have applied various devices to those cases where imaging of fistula was difficult, and achieved complete resection of fistula and have not observed recurrences of infection after resection.

  英語, 研究論文（学術雑誌）, Objective: This study was designed to determine whether biological markers related to apoptosis or proliferative activity are associated with the clinical outcome in patients with squamous cell carcinoma (SCC) of the larynx treated with concurrent chemoradiotherapy. Methods: Immunostaining with antibodies specific to p53, bcl-2, bax, and MIB-1 was performed to evaluate expression of these proteins in formalin-fixed, paraffin-embedded specimens of 59 patients treated with concurrent chemoradiotherapy (carboplatin, 100 mg/m(2), four to six times every week; total radiation dose of 40-65 Gy over 4-6.5 weeks). Results: Multivariate analysis indicated that nodal status was a significant indicator of overall survival (OS; P = 0.001). Patients with bcl-2 positive tumors had better OS than those with bcl-2 negative tumors in both univariate (P = 0.002) and multivariate analyses (P < 0.001). In the univariate analysis, a considerable difference in OS was observed among the expressions of bax (P = 0.077), MIB-I proteins (P = 0.071), and OS, but the difference was not statistically significant. Conclusion: This study indicates that nodal status is the major prognostic factor in patients with SCC of the larynx treated with concurrent chemoradiotherapy. These results provide useful information for predicting prognosis. Further analysis of biological factors is needed to evaluate the value as predictive markers. (C) 2001 Elsevier Science Ireland Ltd.

  英語, 研究論文（学術雑誌）, Concurrent chemoradiotherapy is reported to have a fair clinical outcome with organ preservation for patients with squamous cell carcinoma of the head and neck (SCCHN), The aim of this study was to determine whether biological markers are related to proliferative activity or apoptosis of tumor cells and whether clinical factors are associated with a clinical outcome in SCCHN patients treated with concurrent chemoradiotherapy,
  Immunostaining with antibodies specific for p53, bcl-2, bar, and MIB-1 was performed to evaluate expression of these proteins in formalin-fixed, paraffin-embedded specimens of 111 SCCHN patients treated with concurrent chemoradiotherapy (carboplatin, 100 mg/m(2), four to six times every week; total radiation therapy dose of 40-65 Gy over 4-6.5 weeks).
  Multivariate analysis indicated that nodal status was a significant indicator of overall survival (OS; P = 0.001) and locoregional control (LRC; P = 0.002), In a univariate analysis, patients with a low MIB-1-positive index (< 40%) had better OS than those with a high MLB-l-positive index (greater than or equal to 40%; P = 0.013), although the difference was not statistically significant in a multivariate analysis (P = 0.060), Patients with bcl-2-positive tumors had better LRC than those with bcl-2-negative tumors, based on a multivariate analysis (P = 0.017), No statistically significant association was found between p53 or bar expression and clinical outcome.
  These results indicate that nodal status is the major prognostic factor in SCCHN patients treated with concurrent chemoradiotherapy, In addition, our findings suggest that bcl-2 positivity is associated with better LRC and that the proliferative activity of tumor cells might be prognostic for OS.

  日本語, 1980年から95年までに根治的放射線治療を行った中咽頭癌新鮮例127例の治療成績を分析した.127例は一次治療として局所及び頸部に対して根治的放射線治療が行われた.ほぼ全例がコバルトγ線の1日1回照射の外照射で治療され,1回線量2.5Gy週4回照射で標準的総線量は65ないし70Gyであった.本論文では,まず全体の治療成績を検討した.ついで,口腔内乾燥症の軽減を目的したCTシミュレーターを用いた対側耳下腺をスペアーした照射法の有用性について検討した.原発病変が正中を超えず対側頸部リンパ節転移がない38例に対してウエッジを用いた斜入二門照射を行ったが,口腔内乾燥症が軽減でき,局所・頸部制御率が劣ることなく,有用な治療法と思われた.更に,カルボプラチン週1回同時併用した29例と照射のみの92例の治療成績を比較検討したが,両群間に生存率,局所制御率,頸部制御率に有意差は認めなかった

  日本語, 頸部食道癌のリンパ節転移は, 頸部, 気管傍さらに上縦隔に認められ, 頸部郭清とともに上縦隔郭清が必要とされる。今回我々は上縦隔郭清を行った頸部食道癌症例のリンパ節転移状況とその郭清について検討した。頸部食道癌に進展した下咽頭癌症例においては, 胸部上部食道まで進展した症例を除き, 縦隔リンパ節転移を認めず, 原則的に上縦隔郭清は必要ないと思われた。一方, 頸部食道癌症例においては, No. 105, 106の転移を認め, 上縦隔郭清が必要であると考えられた。組織学的深達度において, 外膜浸潤al以上に縦隔リンパ節転移を認め, 深達度とリンパ節転移の相関が示唆された。頸部食道癌においては, CTなどの画像診断による縦隔リンパ節転移の検索が必要であり, 画像にて描出されたリンパ節群を確実に郭清していくことが重要である。

  日本語, 1)急速に増大する甲状腺腫瘍において術前診断は重要であるが困難である。67Gaシンチグラフィーが診断に有効であり,集積が認められFNAで確定不能の際は生検の施行を方針としている。2)甲状腺未分化癌の治療経験から,QOLを高めるうえでの姑息的手術が大切であると思われた

  日本語, 手術を行った甲状腺腫瘍247例において術前,術後に出現した反回神経麻痺を検討した。1)術前から反回神経麻痺が存在する場合は悪性腫瘍である可能性が高いが,良性腫瘍による圧迫によることもあるため術前検査により良性悪性を診断したうえで手術を行い,温存できる神経は温存する。2)甲状腺癌では反回神経に沿ったリンパ節転移が生じることが多いが,分化癌の場合は強く癒着しておらず剥離可能なことが多く,一過性に麻痺を生じても後に回復することが多い

  英語, 研究論文（学術雑誌）, 1)副鼻腔悪性腫瘍新鮮例の治療成績は,姑息例を含めた全症例で5年生存率54.4%,根治治療例で69.5%であった.治療完結例は79.2%であった. 2)根治治療例の扁平上皮癌21例で77.1%,治療完結例14例で100%と扁平上皮癌に限ると放射線照射と十分な範囲の切除術で局所制御ひいては生存率の向上につながるものと思われる. 3)未分化癌は少数例であったが,集学的治療をもっても制御できなかった

  日本語, 6年間に受診した鼻骨骨折症例について,成因と治療内容に対する満足度等につきアンケート調査を行った。鼻骨骨折の成因では,暴行,交通事故,スポーツの順に多く,それぞれの項目につき更に詳しく成因を検討した。治療に対するアンケートでは,整復後の外観に関しては,83%の患者が満足しているが,約1/3の患者が鼻閉感を訴えた。固定に関しては,内固定に関する不満が多く,固定期間は4日,外固定は7日程度が苦痛を与えないという面ではよい

  英語, 研究論文（学術雑誌）, A 72-year-old woman had noted left submandibular swelling for 7 years. On examination a 5 × 5 cm smooth, hard, fixed, painless mass was palpable in the left submandibular area. CT scan showed a circumscribed, isodense mass near the bifurcation of the carotid artery. Extirpation of the tumor was performed. The pathological diagnosis was intravascular papillary endothelial hyperplasia. The postoperative course was good, and the patient remains free of disease more than 5 months after surgery. Intravascular papillary endothelial hyperplasia is characterized by intravascular endothelial proliferation that resembles angiosarcoma. This disease seems to be the result of a peculiar process of thrombus undergoing organization. The prognosis is good, and the treatment is usually total extirpation of the tumor. © 1993, The Society of Practical Otolaryngology. All rights reserved.
