    英語, 研究論文(学術雑誌), PURPOSE: To evaluate the utility of model-based deep learning reconstruction in prostate diffusion-weighted imaging (DWI). METHODS: This retrospective study evaluated two prostate diffusion-weighted imaging (DWI) methods: deep learning reconstruction (DL-DWI) and traditional parallel imaging (PI-DWI). We examined 32 patients with radiologically diagnosed and histologically confirmed prostate cancer (PCa) lesions ≥10 mm. Image quality was evaluated both qualitatively (for overall quality, prostate conspicuity, and lesion conspicuity) and quantitatively, using the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and apparent diffusion coefficient (ADC) for prostate tissue. RESULTS: In the qualitative evaluation, DL-DWI scored significantly higher than PI-DWI for all three parameters (p<0.0001). In the quantitative analysis, DL-DWI showed significantly higher SNR and CNR values compared to PI-DWI (p<0.0001). Both the prostate tissue and the lesions exhibited significantly higher ADC values in DL-DWI compared to PI-DWI (p<0.0001, p=0.0014, respectively). CONCLUSION: Model-based DL reconstruction enhanced both qualitative and quantitative aspects of image quality in prostate DWI. However, this study did not include comparisons with other DL-based methods, which is a limitation that warrants future research.

    英語, 研究論文(学術雑誌), OBJECTIVES: To determine how the treatment decision-making process and posttreatment health-related quality of life (HRQOL) are related to regret about treatment choice for prostate cancer patients in Japan. METHODS: We invited a total of 614 patients who were treated with radiation therapy (RT), radical prostatectomy (RP), or active surveillance/watchful waiting (AS/WW) from April 2007 to March 2021. Posttreatment regret was evaluated by the Decision Regret Scale. HRQOL was evaluated by the Expanded Prostate Cancer Index Composite and the 12-item Short Form Survey. The decision-making process was assessed by patient evaluation of the decision-making process. We compared the decision regret scale scores across treatment types, HRQOL, and decision-making processes. RESULTS: Data from 371 patients were analyzed (RT: 202, RP: 149, AS/WW: 20). The median length of time since treatment was 64 (IQR: 43-93) months. The decision regret scale scores were not significantly different among the treatment groups but were significantly greater (strong regret) in patients with poor urinary summary scores, bowel summary scores, and hormonal summary scores. The decision regret scale scores were significantly lower (less regret) for patients who reported being adequately informed at the time of the treatment decision and who had adequately communicated their questions and concerns to physicians than for patients who reported less adequate communication. This result was also observed among patients who reported low HRQOL scores. CONCLUSIONS: These findings underline the important influence of posttreatment HRQOL and decision-making as an interactive process between physicians and their patients on posttreatment regret in prostate cancer patients.

    英語, 研究論文(学術雑誌), BACKGROUND: The therapeutic role of pelvic lymph node dissection (PLND) during radical prostatectomy (RP) for prostate cancer is not established. In clinical practice, PLND is primarily performed in cases of high-risk prostate cancer. The detection of lymph node metastasis plays a crucial role in determining the need for subsequent treatments. This study aims to evaluate the prognosis of prostate cancer patients with lymph node involvement (LNI) by stratifying them based on postoperative prostate-specific antigen (PSA) levels to identify biomarkers that can guide postoperative treatment strategies. METHODS: Analysis was conducted on 383 patients, selected from 572 initially eligible, who underwent RP with LNI across 33 Japanese Urological Oncology Group institutions from 2006 to 2019. Patients were grouped according to postoperative PSA levels and salvage treatments received. Follow-up focused on castration resistance-free survival (CRFS), metastasis-free survival (MFS), and overall survival (OS). RESULTS: In the persistent PSA group (PSA ≥ 0.1 ng/mL), CRFS and MFS were significantly shorter compared to the non-persistent PSA group (PSA < 0.1 ng/mL), and there was a tendency for shorter OS. In the persistent PSA group, patients with postoperative PSA values above the median (PSA ≥ 0.52 ng/mL) showed shorter CRFS and MFS. Furthermore, in the PSA ≥ 0.52 group, androgen deprivation therapy (ADT) plus radiotherapy (RT) combination had prolonged CRFS and MFS compared with ADT alone. CONCLUSIONS: This study provides valuable insights into stratifying patients based on postoperative PSA levels to tailor postoperative treatment strategies, potentially improving the prognosis of prostate cancer patients with LNI.

    英語, 研究論文(学術雑誌), PURPOSE: Our aim was to develop practical training for laparoscopic surgery using Thielembalmed cadavers. Furthermore, in order to verbalize experts' motion characteristics and provide objective feedback to trainees, we initiated motion capture analyses of multiple surgical instruments simultaneously during the cadaveric trainings. In the present study, we report our preliminary results. METHODS: Participants voluntarily joined the present cadaveric simulation trainings, and performed laparoscopic radical nephrectomy. After the trainings, scores for tissue similarity (face validity) and impression of educational merit (content validity) were collected from participants based on a 5-point Likert scale (tissue similarity: 5: very similar, 3: average, 1: very different; educational merit: 5: very high, 3: average, 1: very low). In addition, after the additional IRB approval, we started motion capture (Mocap) analyses of 6 surgical instruments (scissors, vessel sealing system, grasping forceps, clip applier, right-angled forceps, and suction), using an infrared trinocular camera (120-Hz location record). Mocap-metrics were compared according to the previous surgical experiences (experts: ≧50 laparoscopic surgeries, intermediates: 10-49, novices: 0-9), using the Kruskal-Wallis test. RESULTS: A total of 9 experts, 19 intermediates, and 15 novices participated in the present study. In terms of face validity, the mean scores were higher than 3, other than for the Vena cava(mean score of 2.89). Participants agreed with the training value (usefulness for future skill improvement: mean score of 4.57). In terms of Mocap analysis, faster speed-related metrics (e.g., velocity, the distribution of tip velocity, acceleration, and jerk) in the scissors and vessel sealing system, a shorter path length of grasping forceps, and fewer dimensionless squared jerks, which indicated more purposeful motion of 4 surgical instruments (vessel sealing system, grasping forceps, clip applier and suction), were observed in the more experienced group. CONCLUSIONS: The Thiel-embalmed cadaver provides an excellent training opportunity for complex laparoscopic procedures with participants' high level of satisfaction, and may become a promising tool for a better objective understanding of surgical dexterity. In order to enrich formative feedback to trainees, we are now proceeding with Mocap analysis.

    英語, 研究論文(学術雑誌), A multicenter study of nonmetastatic castration-resistant prostate cancer (nmCRPC) was conducted to identify the optimal cut-off value of prostate-specific antigen (PSA) doubling time (PSADT) that correlated with the prognosis in Japanese nmCRPC. Of the 515 patients diagnosed and treated for nmCRPC at 25 participating Japanese Urological Oncology Group centers, 450 patients with complete clinical information were included. The prognostic values of clinical factors were evaluated with respect to prostate specific antigen progression-free (PFS), cancer-specific survival (CSS), and overall survival (OS). The optimal cutoff value of PSADT was identified using survival tree analysis by Python. The Median PSA and PSADT at diagnosis of nmCRPC were 3.3 ng/ml, and 5.2 months, respectively. Patients treated with novel hormonal therapy (NHT) showed significantly longer PFS (HR: hazard ratio 0.38, p < 0.0001) and PFS2 (HR 0.45, p < 0.0001) than those treated with vintage nonsteroidal antiandrogen agent (Vintage). The survival tree identified 4.65 months as the most prognostic PSADT cutoff point. Among the clinical and pathological factors PSADT of < 4.65 months remained an independent prognostic factor for OS (HR 2.96, p = 0.0003) and CSS (HR 3.66, p < 0.0001). Current data represented optimal cut-off of PSADT 4.65 months for a Japanese nmCRPC.
  • A surgical instrument motion measurement system for skill evaluation in practical laparoscopic surgery training

    研究論文(学術雑誌), This study developed and validated a surgical instrument motion measurement system for skill evaluation during practical laparoscopic surgery training. Owing to the various advantages of laparoscopic surgery including minimal invasiveness, this technique has been widely used. However, expert surgeons have insufficient time for providing training to beginners due to the shortage of surgeons and limited working hours. Skill transfer efficiency has to be improved for which there is an urgent need to develop objective surgical skill evaluation methods. Therefore, a simple motion capture–based surgical instrument motion measurement system that could be easily installed in an operating room for skill assessment during practical surgical training was developed. The tip positions and orientations of the instruments were calculated based on the marker positions attached to the root of the instrument. Because the patterns of these markers are individual, this system can track multiple instruments simultaneously and detect exchanges. However due to the many obstacles in the operating room, the measurement data included noise and outliers. In this study, the effect of this decrease in measurement accuracy on feature calculation was determined. Accuracy verification experiments were conducted during wet-lab training to demonstrate the capability of this system to measure the motion of surgical instruments with practical accuracy. A surgical training experiment on a cadaver was conducted, and the motions of six surgical instruments were measured in 36 cases of laparoscopic radical nephrectomy. Outlier removal and smoothing methods were also developed and applied to remove the noise and outliers in the obtained data. The questionnaire survey conducted during the experiment confirmed that the measurement system did not interfere with the surgical operation. Thus, the proposed system was capable of making reliable measurements with minimal impact on surgery. The system will facilitate surgical education by enabling the evaluation of skill transfer of surgical skills.

    英語, 研究論文(学術雑誌), OBJECTIVE: To report the outcomes of repeat biopsies, metastasis and survival in the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study, a prospective observational study for Japanese patients, initiated in 2010. PATIENTS AND METHODS: At the beginning, inclusion criteria were initially low-risk patients, prostate-specific antigen (PSA) density (PSAD) <0.2, and ≤2 positive biopsy cores. As from 2014, GS3+4 has also been allowed for patients aged 70 years and over. Since January 2021, the age limit for Gleason score (GS) 3 + 4 cases was removed, and eligibility criteria were expanded to PSA ≤20 ng/mL, PSAD <0.25 nd/mL/cc, unlimited number of positive GS 3 + 3 cores, and positive results for fewer than half of the total number of cores for GS 3 + 4 cases if magnetic resonance imaging fusion biopsy was performed at study enrolment or subsequent follow-up. For patients eligible for active surveillance, PSA tests were performed every 3 months, rectal examination every 6 months, and biopsies at 1, 4, 7 and 10 years, followed by every 5 years thereafter. Patients with confirmed pathological reclassification were recommended for secondary treatments. RESULTS: As of February 2024, 1302 patients were enrolled in AS; 1274 (98%) met the eligibility criteria. The median (interquartile range) age, PSA level, PSAD, and number of positive cores were 69 (64-73) years, 5.3 (4.5-6.6) ng/mL, 0.15 (0.12-0.17) ng/mL, and 1 (1-2), respectively. The clinical stage was T1c in 1089 patients (86%) and T2 in 185 (15%). The rates of acceptance by patients for the first, second, third and fourth re-biopsies were 83%, 64%, 41% and 22%, respectively. The pathological reclassification rates for the first, second, third and fourth re-biopsies were 29%, 30%, 35% and 25%, respectively. The 1-, 5- and 10-year persistence rates were 77%, 45% and 23%, respectively. Six patients developed metastasis, and one patient died from prostate cancer. CONCLUSION: Pathological reclassification was observed in approximately 30% of the patients during biopsy; however, biopsy acceptance rates decreased over time. Although metastasis occurred in six patients, only one death from prostate cancer was recorded.

    英語, 研究論文(学術雑誌), BACKGROUND: This study aimed to create a prognostic model to predict disease recurrence among patients with lymph node involvement but no prostate-specific antigen (PSA) persistence and to explore its clinical utility. METHODS: The study analyzed patients with lymph node involvement after pelvic lymph node dissection with radical prostatectomy in whom no PSA persistence was observed between 2006 and 2019 at 33 institutions. Prognostic factors for recurrence-free survival (RFS) were analyzed by the Cox proportional hazards model. RESULTS: Among 231 patients, 127 experienced disease recurrence. The factors prognostic for RFS were PSA level at diagnosis (≥ 20 vs. < 20 ng/mL: hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.09-2.52; P = 0.017), International Society of Urological Pathology grade group at radical prostatectomy (RP) specimen (group ≥ 4 vs. ≤ 3: HR, 1.63; 95% CI 1.12-2.37; P = 0.010), pathologic T-stage (pT3b/4 vs. pT2/3a: HR, 1.70; 95% CI 1.20-2.42; P = 0.0031), and surgical margin status (positive vs. negative: HR, 1.60; 95% CI 1.13-2.28; P = 0.0086). The prognostic model using four parameters were associated with RFS and metastasis-free survival. CONCLUSION: The prognostic model in combination with postoperative PSA value and number of lymph nodes is clinically useful for discussing treatment choice with patients.

    英語, 研究論文(学術雑誌), New technologies such as laparoscopic and robotic surgery are spreading, and there is a demand for physicians to keep up with novel methods. In contrast to the recent focus on healthcare professional burnout, the mental and physical costs during surgery are not well-understood. We aimed to quantify surgeons' workloads in daily urological surgical practice and clarify potential background factors associated with such workloads. Urologists in Hokkaido, Japan, were invited to this study. Between December 2020 and December 2021, participants repeatedly reported workloads, which were assessed using the National Aeronautics and Space Administration-Task Load Index (NASA-TLX), after each surgery in conjunction with participants' names, patients' backgrounds, their roles (independent operator, operator under supervision, instructor, and 1st or 2nd assistant), and surgical outcomes, via SurveyMonkey®. Because of the heterogeneity among individuals, a linear mixed-effects model was utilized to analyze factors associated with NASA-TLX, calculating the parameter estimates (PE) of regression coefficients for each factor and their 95% confidence interval (CI). Sixty-five urologists (5 women) joined the study, and 2169 data were collected within 7 days after surgeries. A linear mixed-effects model revealed that female surgeons (PE + 15.56, 95% CI 2.36-28.77), urgent/emergency surgery (PE + 6.65, 95% CI 4.59-8.70), intraoperative complications (PE + 9.26, 95% CI 6.76-11.76), and near-miss incidents (PE + 3.81, 95% CI 2.27-5.36) were associated with higher workloads. Regarding the surgeons' role, operator under supervision (PE + 12.46, 95% CI 9.86-15.06) showed the highest workloads. Surgeons' workloads decreased as the number of previous cases of the same procedure increased. Surgeons' workloads were associated with various factors. Given that the highest workloads were for operators under supervision, instructors should be aware of trainees' high workloads and devise appropriate instructional interventions.

    英語, 研究論文(学術雑誌), OBJECTIVE: To assess the effectiveness of pre- and postoperative supervised pelvic floor muscle training (PFMT) on the recovery of continence and pelvic floor muscle (PFM) function after robot-assisted laparoscopic radical prostatectomy (RARP). PATIENTS AND METHODS: We carried out a single-blind randomised controlled trial involving 54 male patients scheduled to undergo RARP. The intervention group started supervised PFMT 2 months before RARP and continued for 12 months after surgery with a physiotherapist. The control group was given verbal instructions, a brochure about PFMT, and lifestyle advice. The primary outcome was 24-h pad weight (g) at 3 months after RARP. The secondary outcomes were continence status (assessed by pad use), PFM function, and the Expanded Prostate Cancer Index Composite (EPIC) score. RESULTS: Patients who participated in supervised PFMT showed significantly improved postoperative urinary incontinence (UI) compared with the control group (5.0 [0.0-908.0] g vs 21.0 [0.0-750.0] g; effect size: 0.34, P = 0.022) at 3 months after RARP based on 24-h pad weight. A significant improvement was seen in the intervention compared with the control group (65.2% continence [no pad use] vs 31.6% continence, respectively) at 12 months after surgery (effect size: 0.34, P = 0.030). Peak pressure during a maximum voluntary contraction was higher in the intervention group immediately after catheter removal and at 6 months, and a longer duration of sustained contraction was found in the intervention group compared with the control group. We were unable to demonstrate a difference between groups in EPIC scores. CONCLUSION: Supervised PFMT can improve postoperative UI and PFM function after RARP. Further studies are needed to confirm whether intra-anal pressure reflects PFM function and affects continence status in UI in men who have undergone RARP.

    英語, 研究論文(学術雑誌), We designed this multi-center prospective study with the following objectives: (1) the cross-sectional validation of extracellular vesicles (EV) mRNA markers to detect urothelial bladder cancer (UBC) before transurethral resection of bladder cancer (TURBT), and (2) the longitudinal validation of EV mRNA markers to monitor non-muscle invasive bladder cancer (NMIBC) recurrence after TURBT. EV mRNA markers evaluated in this study were KRT17, GPRC5A, and SLC2A1 in addition to two additional markers from literatures, MDK and CXCR2, and measured by quantitative RT-PCR with normalization by a reference gene (ALDOB). Diagnostic performances of EV mRNA markers were compared to conventional markers. Regarding the first objective, we confirmed that EV mRNA biomarkers in urine were higher in UBC patients, particularly those with higher stage/grade tumors, than in those without UBC (n = 278 in total) and the diagnostic performance of EV mRNA MDK and KRT17 outperformed conventional biomarkers with AUC 0.760 and 0.730, respectively. Concerning the second objective, we prospectively analyzed the time courses of EV mRNA markers while NMIBC patients (n = 189) (median follow-up 19 months). The expression of EV mRNA KRT17 was significantly high in patients with recurrence, while it gradually decreased over time in those without recurrence (p < 0.01).

    英語, 研究論文(学術雑誌), We evaluated the efficacy and safety of TAS0313, a multi-epitope long peptide vaccine, plus pembrolizumab in post-chemotherapy immune checkpoint inhibitor-naïve patients with locally advanced/metastatic urothelial carcinoma. TAS0313 9 mg was administered subcutaneously followed by pembrolizumab 200 mg on Day 1, and as monotherapy on Day 8 and 15 of Cycles 1 and 2, and Day 1 of subsequent cycles in 21-day cycles. The primary endpoint was the objective response rate (ORR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), and safety. Biomarkers of response were assessed. In 36 patients enrolled, the ORR was 33.3% (complete response: 7 patients; partial response: 5 patients). Median PFS was 5.0 months; 6- and 12-month progression free rates (PFRs) were 46.4% and 36.5%, respectively. Median OS was not reached; 6-, 12- and 24-month OS rates were 83.3%, 72.2%, and 55.1%, respectively. In post-hoc analysis, patients with a tumor infiltrating CD8+ lymphocyte (CD8+ TIL) count ≥99 and/or programmed cell death protein 1 (PD-L1) Combined Positive Score (CPS) ≥50 and lymphocyte count >1380 cells/μL had higher ORRs and prolonged PFS versus patients with a CD8+ TIL count <99, PD-L1 CPS <50, and lymphocyte count ≤1380 cells/μL. Thirty-four (94.4%) patients receiving combination therapy experienced treatment-related adverse events (AEs), with pyrexia (n=15, 41.7%), injection-site reactions (n=15, 41.7%), injection-site induration (n=6, 16.7%), and malaise (n=6, 16.7%) the most common. No grade ≥3 treatment-related AEs occurred in ≥10% of patients. TAS0313 plus pembrolizumab combination therapy showed promising efficacy and manageable safety in locally advanced/metastatic urothelial carcinoma.

    英語, 研究論文(学術雑誌), OBJECTIVE: Several guidelines recommended that second transurethral resection should be performed in patients with diagnosis of high-risk non-muscle-invasive bladder cancer. However, therapeutic benefits of second transurethral resection before bacillus Calmette-Guérin intravesical instillation were conflicting amongst previous studies. We investigated the prognostic impact of second transurethral resection before bacillus Calmette-Guérin instillation in high-risk non-muscle-invasive bladder cancer patients. METHODS: This retrospective study included 3104 non-muscle-invasive bladder cancer patients who received bacillus Calmette-Guérin instillations between 2000 and 2019 at 31 collaborative institutions. Univariate and multivariate Cox proportional hazards models were used to assess the risk factors of intravesical recurrence, disease progression, cancer-specific mortality and overall mortality. RESULTS: In the entire population, patients undergoing second transurethral resection (33%, 1026/3104) had a lower risk of intravesical recurrence on univariate analysis (hazard ratio 0.85, 95% confidence interval 0.73-0.98, P = 0.027), although it did not remain significant on multivariate analysis (hazard ratio 0.90, 95% confidence interval 0.76-1.07, P = 0.24). Subgroup analysis revealed that, in pT1 patients (n = 1487), second transurethral resection was significantly correlated with a lower risk of intravesical recurrence on multivariate analysis (hazard ratio 0.80, 95% confidence interval 0.64-1.00, P = 0.048), but lower risks of disease progression (hazard ratio 0.75, 95% confidence interval 0.56-1.00, P = 0.049), cancer-specific mortality (hazard ratio 0.54, 95% confidence interval 0.35-0.85, P = 0.007) and overall mortality (hazard ratio 0.73, 95% confidence interval 0.55-0.97, P = 0.027) on univariate analysis. CONCLUSIONS: Second transurethral resection confers accurate pathological staging and could be used to safely select good candidates for intravesical bacillus Calmette-Guérin instillation. We further confirm that second transurethral resection could confer an oncological benefit in pT1 bladder cancer patients treated by bacillus Calmette-Guérin instillation, and so strongly recommend second transurethral resection in this patient population.

    日本語, 研究論文(学術雑誌), A 23-year-old male was aware of pain around his left hip joint and visited a nearby orthopedic clinic. Swelling of the right testis was pointed out, and a testicular tumor was suspected. He was referred to the urology department of a local hospital. Blood analysis showed an increase of α-fetoprotein (AFP) (3,620 ng/ml). Computed tomographic (CT) -scan revealed a left iliac bone metastasis and morbid fracture. Right radical inguinal orchiectomy was performed. The pathological examination revealed mixed germ cell tumor (embryonic carcinoma and immature teratoma: 70%, seminoma: 30%). The diagnosis was non-seminomatous germ cell tumor, stage IIIc, and poor risk on the International Germ Cell Consensus Classification. After one cycle of a bleomycin, etoposide and cisplatinum (BEP) regimen, he was referred to our hospital. After a total of 4 cycles of BEP, AFP was normalized. Denosumab was also administered monthly. The CT-scan showed a reduction of bone metastasis and recovery of ossification. Bone biopsy did not show viable tumor cells. Because extirpation of the remaining mass would require resection of the left part of the pelvic bone with significant functional loss of the left limb, we performed close follow-up after an additional 2 courses of the etoposide and cisplatin regimen. The patient is currently alive without recurrence at 45 months after the last systemic chemotherapy.

    英語, 研究論文(学術雑誌), BACKGROUND: In men undergoing upfront active surveillance, predictors of adverse pathology in radical prostatectomy specimens, including intraductal carcinoma of the prostate and cribriform patterns, remain unknown. Therefore, we aimed to examine whether adverse pathology in radical prostatectomy specimens could be predicted using preoperative patient characteristics. METHODS: We re-reviewed available radical prostatectomy specimens from 1035 men prospectively enrolled in the PRIAS-JAPAN cohort between January 2010 and September 2020. We defined adverse pathology on radical prostatectomy specimens as Gleason grade group ≥3, pT stage ≥3, pN positivity or the presence of intraductal carcinoma of the prostate or cribriform patterns. We also examined the predictive factors associated with adverse pathology. RESULTS: All men analyzed had Gleason grade group 1 specimens at active surveillance enrolment. The incidence of adverse pathologies was 48.9% (with intraductal carcinoma of the prostate or cribriform patterns, 33.6%; without them, 15.3%). The addition of intraductal carcinoma of the prostate or cribriform patterns to the definition of adverse pathology increased the incidence by 10.9%. Patients showing adverse pathology with intraductal carcinoma of the prostate or cribriform patterns had lower biochemical recurrence-free survival (log-rank P = 0.0166). Increasing age at active surveillance enrolment and before radical prostatectomy was the only predictive factor for adverse pathology (odds ratio: 1.1, 95% confidence interval: 1.02-1.19, P = 0.0178; odds ratio: 1.12, 95% confidence interval: 1.02-1.22, P = 0.0126). CONCLUSIONS: Increasing age could be a predictive factor for adverse pathology. Our findings suggest that older men could potentially derive advantages from adhering to the examination schedule in active surveillance.

    英語, 研究論文(学術雑誌), OBJECTIVE: To determine the impact of postoperative complications on long-term survival outcomes in patients with bladder cancer undergoing radical cystectomy. METHODS: This retrospective multi-institutional study included 766 bladder cancer patients who underwent radical cystectomy between 2011 and 2017. Patient characteristics, perioperative outcomes, all complications within 90 days after surgery and survival outcomes were collected. Each complication was graded based on the Clavien-Dindo system, and grouped using a standardized grouping method. The Comprehensive Complication Index, which incorporates all complications into a single formula weighted by their severity, was utilized. Overall survival and recurrence-free survival (local, distant or urothelial recurrences) were stratified by Comprehensive Complication Index (high: ≥26.2; low: <26.2). A multivariate model was utilized to identify independent prognostic factors. RESULTS: The incidence of any and major complications (≥Clavien-Dindo grade III) was 70 and 24%, respectively. In terms of Comprehensive Complication Index, 34% (261/766) of the patients had ≥26.2. Patients with Comprehensive Complication Index ≥ 26.2 had shorter overall survival (4-year, 59.5 vs. 69.8%, respectively, log-rank test, P = 0.0037) and recurrence free survival (51.9 vs. 60.1%, respectively, P = 0.0234), than those with Comprehensive Complication Index < 26.2. The Cox multivariate model identified the age, performance status, pT-stage, pN-stage and higher CCI (overall survival: HR = 1.35, P = 0.0174, recurrence-free survival: HR = 1.26, P = 0.0443) as independent predictors of both overall survivial and recurrence-free survival. CONCLUSIONS: Postoperative complications assessed by Comprehensive Complication Index had adverse effects on long-term survival outcomes. Physicians should be aware that major postoperative complications can adversely affect long-term disease control.

    英語, 研究論文(学術雑誌), We investigated the ability of echo-planar imaging with L1-regularized iterative sensitivity encoding-based diffusion-weighted imaging (DWI) to improve the image quality and reduce the scanning time in prostate magnetic resonance imaging. We retrospectively analyzed 109 cases of prostate magnetic resonance imaging. We compared variables in the quantitative and qualitative assessments among 3 imaging groups: conventional parallel imaging-based DWI (PI-DWI) with an acquisition time of 3 minutes 15 seconds; echo-planar imaging with L1-regularized iterative sensitivity encoding-based DWI (L1-DWI) with a normal acquisition time (L1-DWINEX12) of 3 minutes 15 seconds; and L1-DWI with a half acquisition time (L1-DWINEX6) of 1 minute 45 seconds. As a quantitative assessment, the signal-to-noise ratio (SNR) of DWI (SNR-DWI), the contrast-to-noise ratio (CNR) of DWI (CNR-DWI), and the CNR of apparent diffusion coefficient were measured. As a qualitative assessment, the image quality and visual detectability of prostate carcinoma were evaluated. In the quantitative analysis, L1-DWINEX12 showed significantly higher SNR-DWI than PI-DWI (P = .0058) and L1-DWINEX6 (P < .0001). In the qualitative analysis, the image quality score for L1-DWINEX12 was significantly higher than those of PI-DWI and L1-DWINEX6. A non-inferiority assessment demonstrated that L1-DWINEX6 was non-inferior to PI-DWI in terms of both quantitative CNR-DWI and qualitative grading of image quality with a <20% inferior margin. L1-DWI successfully demonstrated a reduced scanning time while maintaining good image quality.

    英語, 研究論文(学術雑誌), OBJECTIVES: To compare the therapeutic features and oncological outcomes of robot-assisted radical prostatectomy (RARP) with those of open radical prostatectomy (ORP) or laparoscopic radical prostatectomy (LRP) in lymph node (LN) positive prostate cancer patients in a retrospective observational multi-institutional study. PATIENTS AND METHODS: We evaluated the clinical results of 561 patients across 33 institutions who underwent RARP, LRP, or ORP and who were diagnosed with LN-positive prostate cancer during RP with pelvic LN dissection (PLND). We determined the following survival outcomes: metastasis-free survival, overall survival, cancer-specific survival, and biochemical recurrence-free survival. The Kaplan-Meier method, log-rank test, and Cox proportional hazards regression model were used to evaluate the effect of treatment on oncological outcomes. Statistical significance was set at P < 0.05. RESULTS: There was no significant difference for any of the survival outcomes between the three surgical groups. However, RARP achieved a greater LN yield compared to that of ORP or LRP. When the extent of PLND was limited to the obturator LNs, the number of removed LNs (RLNs) was comparable between the three surgical groups. However, higher numbers of RLNs were achieved with RARP compared to the number of RLNs with ORP (P < 0.001) when PLND was extended to the external and/or internal iliac LNs. CONCLUSION: RARP, LRP, and ORP provided equal surgical outcomes for pN1 prostate cancer, and the prognosis was relatively good for all procedures. Increased numbers of RLNs may not necessarily affect the oncological outcome.

    英語, 研究論文(学術雑誌), The Body Image Scale (BIS) is a 10-item tool that measures the body images of cancer patients. This study aims to validate the Japanese version of the BIS for bladder cancer patients. A multicenter cross-sectional survey was used to identify the participants, which included Japanese bladder cancer patients. The percentage of missing responses, internal consistency, and known-group validity were evaluated. The correlations between the BIS and two HRQOL instruments (the Bladder Cancer Index and the SF-12) were assessed to determine convergent validity. Among 397 patients, 221 patients were treated by transurethral resection of bladder tumor (TURBT) endoscopically, 49 patients underwent cystectomy with neobladder, and 127 patients underwent cystectomy involving stoma. The percentage of missing responses in the BIS ranged from 8.1 to 15.6%. Cronbach's α coefficient was 0.924. Higher BIS scores indicate negative body image, and the median BIS score for patients with native bladders after TURBT (0.5) was significantly lower than those of the patients with neobladder (4.0) and stoma formation (7.0), which indicated the discriminatory ability of the BIS. Each domain of the Bladder Cancer Index and the role summary score of the SF-12 correlated to the BIS scores, which confirmed the convergent validity. A range of BIS scores were identified among patients who reported similar physical summary scores and mental summary scores of the SF-12. This study confirmed the reliability and validity of the Japanese version of the BIS for bladder cancer patients.

    英語, BACKGROUND: Among early stage prostate cancer patients, intraductal carcinoma of the prostate (IDC-P) and invasive cribriform are key prognostic factors; however, their presence and clinical significance following active surveillance (AS) are unknown. In men who opted for AS, we aimed to examine the presence and impact of IDC-P or cribriform, utilizing radical prostatectomy (RP) specimens. METHODS: We re-reviewed 137 RP specimens available in the PRIAS-JAPAN prospective cohort between January 2010 and September 2020. We assessed the presence of IDC-P or cribriform, and compared the patients' characteristics and prostate-specific antigen (PSA) recurrence-free survival after RP between groups with and without IDC-P or cribriform. In addition, we examined the predictive factors associated with IDC-P or cribriform. RESULTS: The percentage of patients with IDC-P or cribriform presence was 34.3% (47 patients). IDC-P or cribriform pattern was more abundant in the higher Gleason grade group in RP specimens (P < 0.001). The rates of PSA recurrence-free survival were significantly lower in the IDC-P or cribriform groups than in those without them (log rank P = 0.0211). There was no association between IDC-P or cribriform on RP with the Prostate Imaging-Reporting and Data System (PI-RADS) 4,5 score on magnetic resonance imaging (MRI) before RP even with adjustments for other covariates (OR, 1.43; 95% confidence interval [CI] 0.511-3.980, P = 0.497). CONCLUSIONS: IDC-P or cribriform comprised approximately one-third of all RP specimens in men who underwent RP following AS, confirming their prognostic significance.

    英語, 研究論文(学術雑誌), OBJECTIVES: This study analyzes the relationship between biglycan expression in prostate cancer and clinicopathological parameters to clarify the potential link between biglycan and prognosis and progression to castration-resistant prostate cancer (CRPC). METHODS: We retrospectively analyzed 60 cases of prostate cancer patients who underwent robot-assisted laparoscopic radical prostatectomy in Hokkaido University Hospital. RESULTS: Biglycan was expressed in the tumor stroma but not in tumor cells. There was no significant relationship with biochemical recurrence (p = 0.5237), but the expression of biglycan was 36.1% in the group with progression to CRPC. This indicates a significant relationship with progression to CRPC (p = 0.0182). Furthermore, the expression of biglycan-positive blood vessels was significantly higher (15.9%) in the group with biochemical recurrence than in the group without biochemical recurrence (8.5%) (p = 0.0169). The biglycan-positive vessels were 28.6% in the group with progression to CRPC, which was significantly higher than that in the group without progression to CRPC (p < 0.0001). CONCLUSION: This is the first study to show that stroma biglycan is a useful prognostic factor for prostate cancer.

    英語, 研究論文(学術雑誌), BACKGROUND: The effect of enzalutamide in patients with non-metastatic castration-resistant prostate cancer after combined androgen blockade, which represents a patient profile similar to real-world clinical practice in Japan, remains unknown. Therefore, we investigate the efficacy and safety of enzalutamide after combined androgen blockade for recurrence following radical treatment in Japanese patients with non-metastatic castration-resistant prostate cancer. METHODS: We analyzed 66 patients with non-metastatic castration-resistant prostate cancer after combined androgen blockade for recurrence following radical prostatectomy or radiation therapy who were prospectively enrolled from October 2015 to March 2018. They received enzalutamide 160 mg orally once daily until the protocol treatment discontinuation criteria were met. The primary endpoint was prostate-specific antigen-progression-free survival, defined as the time from enrollment to prostate-specific antigen-based progression or death from any cause. The secondary endpoints included overall survival, progression-free survival, metastasis-free survival, time to prostate-specific antigen progression, prostate-specific antigen response rate, chemotherapy-free survival, and safety assessment. RESULTS: The median observation period was 27.3 months. The median prostate-specific antigen-progression-free survival was 35.0 months (95% confidence interval, 17.5 to not reached). The median overall survival, median progression-free survival, median metastasis-free survival, and chemotherapy-free survival were not reached, with the corresponding 2-year rates being 91.6%, 67.1%, 72.4%, and 85.8%, respectively. The 50% prostate-specific antigen response rate was 88.9%, with the median time being 2.8 months. In total, 42.2% of the patients experienced adverse events, with malaise being the most common. CONCLUSIONS: Enzalutamide effectively manages non-metastatic castration-resistant prostate cancer after combined androgen blockade for recurrence following radical treatment.

    英語, 研究論文(学術雑誌), INTRODUCTION: We report a case of laparoscopic adrenalectomy in a salvage setting after multiple chemotherapies for neuroendocrine carcinoma. CASE PRESENTATION: A 49-year-old man was diagnosed with unknown primary carcinoma with single brain metastasis, and right supraclavicular and mediastinal lymph node metastases. After stereotactic radiotherapy of the brain metastasis and systemic chemotherapy, lymphadanectomy was performed. The pathologic diagnosis was neuroendocrine carcinoma. At 11 months after surgery, computed tomography revealed right adrenal metastasis. Local radiotherapy initially resulted in complete remission. However, adrenal recurrence was noted 10 months later. Laparoscopic adrenalectomy was performed with curative intent. The patient is currently alive without recurrence at 20 months after the operation. CONCLUSION: Adrenalectomy can become a treatment option if other metastases are well-controlled with systemic therapy. Surgical elimination of oligometastases can offer long-term disease control in selected patients as part of a multimodal approach.

    英語, 研究論文(学術雑誌), OBJECTIVES: To compare the medical costs of active surveillance with those of robot-assisted laparoscopic prostatectomy, brachytherapy, intensity-modulated radiation therapy, and hormone therapy for low-risk prostate cancer. METHODS: The costs of protocol biopsies performed in the first year of surveillance (between January 2010 and June 2020) and those of brachytherapy and radiation therapy performed between May 2019 and June 2020 at the Kagawa University Hospital were analyzed. Hormone therapy costs were assumed to be the costs of luteinizing hormone-releasing hormone analogs for over 5 years. Active surveillance-eligible patients were defined based on the following: age <74 years, ≤T2, Gleason score ≤6, prostate-specific antigen level ≤10 ng/ml, and 1-2 positive cores. We estimated the total number of active surveillance-eligible patients in Japan based on the Japan Study Group of Prostate Cancer (J-CAP) study and the 2017 cancer statistical data. We then calculated the 5-year treatment costs of active surveillance-eligible patients using the J-CAP and PRIAS-JAPAN study data. RESULTS: In 2017, number of active surveillance-eligible patients in Japan was estimated to be 2808. The 5-year total costs of surveillance, prostatectomy, brachytherapy, radiation therapy, and hormone therapy were 1.65, 14.0, 4.61, 4.04, and 5.87 million United States dollar (USD), respectively. If 50% and 100% of the patients in each treatment group had opted for active surveillance as the initial treatment, the total treatment cost would have been reduced by USD 6.89 million (JPY 889 million) and USD 13.8 million (JPY 1.78 billion), respectively. CONCLUSION: Expanding active surveillance to eligible patients with prostate cancer helps save medical costs.

    英語, This paper describes details of the development of skill evaluation system for laparoscopic surgical procedure. The measurement experiment was conducted for 70 surgeons, and the participants perform 2 tasks: tissue dissection around the aorta and renal parenchymal suturing/knotting using porcine cadaver. In the experiments, the movement of surgical instruments were recorded by motion capture (MoCap) system, and the motion indices were calculated. The participants grouped into three classes (novices, intermediates, and experts) according to their level of experience. Three classification algorithms: support vector machine (SVM), principal component based SVM (PCA-SVM), gradient boosting decision tree (GBDT) were utilized for developing the model of classifier. The accuracy of each model was assessed by nested and repeated k-fold cross validation. Regarding 3-class classification, the GBDT method resulted highest accuracy (the median of the accuracy is A_med = 68.6 %) in the dissection tasks. In the suturing/knotting tasks, PCA-SVM resulted highest accuracy (A_med = 58.4 %). Regarding 2-class classification (experts vs. intermediates/novices), the GBDT method resulted A_med = 72.9 % in the dissection task, and the PCA-SVM method resulted A_med = 69.2 % in the suturing task. This result shows the MoCap based skill evaluation system in wet-lab training could be a practical way to objectively assess trainees' surgical competence.

    英語, A 62-year-old woman presented with a tumor in the right kidney. A right partial nephrectomy was performed, and the tumor was diagnosed as clear cell renal cell carcinoma (RCC) on histopathological examination. A right ovarian tumor was detected on follow-up computed tomography (CT) 5 years after partial nephrectomy and pathology proved RCC metastasis. RCC rarely metastasizes to the ovaries. There is limited information on the radiological features of ovarian metastasis in RCC. In this case report, we presented the CT and magnetic resonance images of ovarian metastasis of RCC. In addition, we also presented a literature review with special emphasis on the imaging features of ovarian metastasis of RCC.

    英語, 研究論文(学術雑誌), OBJECTIVES: This study aimed to evaluate whether oncological outcomes of radical prostatectomy differ depending on adherence to the criteria in patients who opt for active surveillance. MATERIALS AND METHODS: We retrospectively reviewed the data of 1035 patients enrolled in a prospective cohort of the PRIAS-JAPAN study. After applying the exclusion criteria, 136 of 162 patients were analyzed. Triggers for radical prostatectomy due to pathological reclassification on repeat biopsy were defined as on-criteria. Off-criteria triggers were defined as those other than on-criteria triggers. Unfavorable pathology on radical prostatectomy was defined as pathological ≥T3, ≥GS 4 + 3 and pathological N positivity. We compared the pathological findings on radical prostatectomy and prostate-specific antigen recurrence-free survival between the two groups. The off-criteria group included 35 patients (25.7%), half of whom received radical prostatectomy within 35 months. RESULTS: There were significant differences in median prostate-specific antigen before radical prostatectomy between the on-criteria and off-criteria groups (6.1 vs. 8.3 ng/ml, P = 0.007). The percentage of unfavorable pathologies on radical prostatectomy was lower in the off-criteria group than that in the on-criteria group (40.6 vs. 31.4%); however, the differences were not statistically significant (P = 0.421). No significant difference in prostate-specific antigen recurrence-free survival was observed between the groups during the postoperative follow-up period (median: 36 months) (log-rank P = 0.828). CONCLUSIONS: Half of the off-criteria patients underwent radical prostatectomy within 3 years of beginning active surveillance, and their pathological findings were not worse than those of the on-criteria patients.

    英語, 研究論文(学術雑誌), The treatment for lymph node involvement (LNI) after radical prostatectomy (RP) has not been established. This study aimed to reveal the outcomes of various management strategies among patients with LNI after RP. Retrospectively, 561 patients with LNI after pelvic lymph node dissection (PLND) with RP treated between 2006 and 2019 at 33 institutions participating in the Japanese Urological Oncology Group were investigated. Metastasis-free survival (MFS) was the primary outcome. Patients were stratified by prostate-specific antigen (PSA) persistence after RP. Cox regression models were used to analyze the relationships between clinicopathological characteristics and survival. Survival analyses were conducted using the Kaplan-Meier method and log-rank test with or without propensity score matching. Prognoses, including MFS and overall survival, were prominently inferior among patients with persistent PSA compared with those without persistent PSA. In multivariate analysis, androgen deprivation therapy (ADT) plus radiotherapy (RT) was associated with better MFS than ADT alone among patients with persistent PSA (hazard ratio = 0.37; 95% confidence interval = 0.15-0.93; p = 0.034). Similarly, MFS and overall survival were significantly better for ADT plus RT than for ADT alone among patients with persistent PSA after propensity score matching. This study indicated that PSA persistence in LNI prostate cancer increased the risk of poor prognoses, and intensive treatment featuring the addition of RT to ADT might improve survival.

    英語, 研究論文(学術雑誌), BACKGROUND: Our aim was to build a skill assessment system, providing objective feedback to trainees based on the motion metrics of laparoscopic surgical instruments. METHODS: Participants performed tissue dissection around the aorta (tissue dissection task) and renal parenchymal closure (parenchymal-suturing task), using swine organs in a box trainer under a motion capture (Mocap) system. Two experts assessed the recorded movies, according to the formula of global operative assessment of laparoscopic skills (GOALS: score range, 5-25), and the mean scores were utilized as objective variables in the regression analyses. The correlations between mean GOALS scores and Mocap metrics were evaluated, and potential Mocap metrics with a Spearman's rank correlation coefficient value exceeding 0.4 were selected for each GOALS item estimation. Four regression algorithms, support vector regression (SVR), principal component analysis (PCA)-SVR, ridge regression, and partial least squares regression, were utilized for automatic GOALS estimation. Model validation was conducted by nested and repeated k-fold cross validation, and the mean absolute error (MAE) was calculated to evaluate the accuracy of each regression model. RESULTS: Forty-five urologic, 9 gastroenterological, and 3 gynecologic surgeons, 4 junior residents, and 9 medical students participated in the training. In both tasks, a positive correlation was observed between the speed-related parameters (e.g., velocity, velocity range, acceleration, jerk) and mean GOALS scores, with a negative correlation between the efficiency-related parameters (e.g., task time, path length, number of opening/closing operations) and mean GOALS scores. Among the 4 algorithms, SVR showed the highest accuracy in the tissue dissection task ([Formula: see text]), and PCA-SVR in the parenchymal-suturing task ([Formula: see text]), based on 100 iterations of the validation process of automatic GOALS estimation. CONCLUSION: We developed a machine learning-based GOALS scoring system in wet lab training, with an error of approximately 1-2 points for the total score, and motion metrics that were explainable to trainees. Our future challenges are the further improvement of onsite GOALS feedback, exploring the educational benefit of our model and building an efficient training program.

    英語, INTRODUCTION: Granulocyte colony-stimulating factor-producing upper urinary tract urothelial carcinoma is rare, with a poor prognosis. Advanced urothelial carcinoma is currently treated with immune checkpoint inhibitors, whose efficacy for granulocyte colony-stimulating factor-producing upper urinary tract urothelial carcinoma remains unclear. CASE PRESENTATION: A 66-year-old male diagnosed with clinical stage T3N1M0 urothelial carcinoma of the right ureter with giant hydronephrosis underwent right radical nephroureterectomy. Local recurrence, leukocytosis, and elevated serum granulocyte colony-stimulating factor levels were observed approximately 3 months after surgery. Chemotherapy was started but failed to control the disease. Therefore, pembrolizumab was chosen as the second-line treatment. After this treatment, the blood leukocyte count rapidly normalized, and a clinically favorable response was achieved. There was no recurrence 10 months after the beginning of pembrolizumab treatment, which is still ongoing. CONCLUSION: Pembrolizumab may be a treatment option for advanced granulocyte colony-stimulating factor-producing upper urinary tract urothelial carcinoma.

    日本語, 研究論文(学術雑誌), A 57-year-old man visited the urology department with a painful mass on the dorsal side of the penis. Magnetic resonance imaging sagittal image showed a small nodule. Leukemia recurrence was suspected due to his history of treatment for acute myeloid leukemia treated with allogeneic hematopoietic stem cell transplantation. No recurrence was identified by bone marrow biopsy ; however, two months later, the recurrence of leukemia was strongly suspected because the tumor grew over time and blasts were found in the peripheral blood. A biopsy of the penile tumor and bone marrow was performed, leading to the diagnosis of granulocytic sarcoma. Patients with a history of leukemia may be preceded by a single recurrence to extramedullary organs, even if blood and bone marrow findings suggest remission.

    英語, 研究論文(学術雑誌), An expanded heterohelicene consisting of three BN2-embedded [4]helicene subunits (V-DABNA-Mes) has been synthesized by one-shot triple borylation. The key to success is the excessive use of boron tribromide in an autoclave. Based on the multiple resonance effect of three boron and six nitrogen atoms, V-DABNA-Mes exhibited a narrowband sky-blue thermally activated delayed fluorescence with a full width at half-maximum of 16 nm. The resonating π-extension minimized the singlet-triplet energy gap and enabled rapid reverse intersystem crossing with a rate constant of 4.4 × 105 s-1. The solution-processed organic light-emitting diode device, employed as an emitter, exhibited a narrowband emission at 480 nm with a high external quantum efficiency of 22.9%.

    日本語, 研究論文(学術雑誌), We report a case of bladder cancer in a 54-year-old woman who underwent renal transplantation for chronic renal failure. Six years after the transplantation, she was diagnosed with muscle-invasive bladder cancer with multiple lung metastases. She received gemcitabine/cisplatin therapy for Stage IV bladder cancer, and the dose of the immunosuppressants was reduced to prevent adverse effects. Since lung metastatic lesions disappeared after four courses of chemotherapy and no new lesions were found, we performed radical cystectomy and right nephroureterectomy with ileal conduit construction. Although she was followed closely without therapy, multiple lung metastases appeared 6 months after the radical cystectomy. Gemcitabine/carboplatin therapy was administered, and the lung metastasis improved slightly until the end of the 4th course, but aggressive growth was observed after the 5th course. She switched to palliative treatment without requesting additional treatment and died of cancer 1 year and 9 months after total cystectomy.There is no evidence-based treatment strategy for advanced bladder cancer after kidney transplantation. It is necessary to recognize that the patient had renal dysfunction and was in an immunosuppressed state. Thus, it is crucial to select appropriate drug and surgical treatments for each patient.

    英語, 研究論文(学術雑誌), BACKGROUND: The quality of transurethral resection of bladder tumor (TURBT) markedly varies among surgeons and may have a considerable impact on treatment outcomes. The importance of a surgical checklist for TURBT has been suggested in order to standardize the procedure and improve surgical and oncological outcomes. In the present study, we verified the usefulness of a checklist for managing patients with non-muscle-invasive bladder cancer (NMIBC). METHODS: This retrospective study included 201 NMIBC patients diagnosed with Ta, T1, or Tis between October 2011 and February 2021. After September 2016, TURBT was performed with a checklist. We analyzed the intravesical recurrence-free survival (RFS) rate and the presence or absence of the detrusor muscle in resected specimens before and after the introduction of the checklist. Survival rates were compared using the Log-rank test. A multivariate analysis with Cox proportional hazards modeling was performed to verify risk factors for intravesical recurrence. RESULTS: Ninety-nine patients who underwent TURBT with the checklist (checklist group) were compared with 102 patients who underwent TURBT without the checklist (non-checklist group). When the analysis was narrowed down to 9 critical items, we observed a mean number of 9 documented items per operative report (98.0% completion) after implementation of the checklist. Two-year intravesical RFS rates in the checklist and non-checklist groups were 76.7 and 69.5%, respectively (p = 0.1059). The Cox proportional multivariate analysis showed that the rate of intravesical recurrence was slightly lower in the checklist group (hazard ratio 0.7376, 95% CI 0.4064-1.3388, P = 0.3170). CONCLUSION: The introduction of a checklist is recommended for the standardization of TURBT and increasing the quality of operative reporting, and it may also improve oncological outcomes.

    英語, 研究論文(学術雑誌), The purpose of this study was to characterize the motion features of surgical devices associated with laparoscopic surgical competency and build an automatic skill-credential system in porcine cadaver organ simulation training. Participants performed tissue dissection around the aorta, dividing vascular pedicles after applying Hem-o-lok (tissue dissection task) and parenchymal closure of the kidney (suturing task). Movements of surgical devices were tracked by a motion capture (Mocap) system, and Mocap-metrics were compared according to the level of surgical experience (experts: ≥50 laparoscopic surgeries, intermediates: 10-49, novices: 0-9), using the Kruskal-Wallis test and principal component analysis (PCA). Three machine-learning algorithms: support vector machine (SVM), PCA-SVM, and gradient boosting decision tree (GBDT), were utilized for discrimination of the surgical experience level. The accuracy of each model was evaluated by nested and repeated k-fold cross-validation. A total of 32 experts, 18 intermediates, and 20 novices participated in the present study. PCA revealed that efficiency-related metrics (e.g., path length) significantly contributed to PC 1 in both tasks. Regarding PC 2, speed-related metrics (e.g., velocity, acceleration, jerk) of right-hand devices largely contributed to the tissue dissection task, while those of left-hand devices did in the suturing task. Regarding the three-group discrimination, in the tissue dissection task, the GBDT method was superior to the other methods (median accuracy: 68.6%). In the suturing task, SVM and PCA-SVM methods were superior to the GBDT method (57.4 and 58.4%, respectively). Regarding the two-group discrimination (experts vs. intermediates/novices), the GBDT method resulted in a median accuracy of 72.9% in the tissue dissection task, and, in the suturing task, the PCA-SVM method resulted in a median accuracy of 69.2%. Overall, the mocap-based credential system using machine-learning classifiers provides a correct judgment rate of around 70% (two-group discrimination). Together with motion analysis and wet-lab training, simulation training could be a practical method for objectively assessing the surgical competence of trainees.

    PloS one, 17, 3, e0265230, 2022年, [国際誌]
    英語, 研究論文(学術雑誌), BACKGROUND: Immune checkpoint inhibitors (ICIs) are increasingly being used to treat malignancies. Some patients experience immune-related adverse events (irAEs), which may affect any organ/tissue. IrAEs are occasionally fatal and usually have nonspecific symptoms. We developed a three-step application (https://irae-search.com/) to provide healthcare professionals with information on the diagnosis, treatment options, and published reports for 38 categories of irAEs encountered in clinical practice. METHODS: IrAEs reported in ≥5 cases were identified from articles published between October 2018 and August 2020 by searching Japanese (SELIMIC, JAPIC-Q Service, and JMED Plus) and international (MEDLINE, EMBASE, Derwent Drug File) databases. The cases' symptoms were entered into the application to identify irAEs, which were verified using the reported diagnosis, to evaluate the application's sensitivity and specificity. RESULTS: Overall, 1209 cases (1067 reports) were analyzed. The three most common categories of irAEs were pituitary or adrenal disorders (14% of cases), skin disorders (13%), and diabetes mellitus (10%). The top three primary diseases were lung cancer (364 cases), melanoma (286 cases), and renal cell carcinoma (218 cases). The average sensitivity was 90.8% (range 44.4%-100.0%) initially, and improved to 94.8% (range 83.3%-100.0%) after incorporating the symptoms reported in published cases into the application's logic for two irAE categories. The average specificity was 79.3% (range 59.1% [thyroid disorders]-98.2% [arthritis]). CONCLUSION: irAE Search is an easy-to-use application designed to help healthcare professionals identify potential irAEs in ICI-treated patients in a timely manner to facilitate prompt management/treatment. The application showed high sensitivity and moderate-to-high specificity for detecting irAEs.

    英語, 研究論文(学術雑誌), OBJECTIVES: With the emergence of several effective combination therapies, information on their effects at the primary site will be crucial for planning future cytoreductive nephrectomy (CN). The present study focused exclusively on changes in primary tumor sizes following treatment with nivolumab plus ipilimumab and investigated the clinical factors associated with a good response in primary tumors. METHODS AND MATERIALS: We retrospectively assessed 27 patients diagnosed with advanced renal cell carcinoma (RCC) who started treatment with nivolumab plus ipilimumab. Changes in tumor sizes at the primary site were described using waterfall and spider plots, respectively. We analyzed the correlation of tumor shrinkage between primary and metastatic site. The parameters analyzed between responders and non-responders according to primary tumor sizes were International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) risk scores, peripheral blood markers, and CRP. RESULTS: The median age and follow-up period were 66 years and 9.3 months, respectively. The median IMDC risk score was 3 (range: 1-6). Nineteen patients were diagnosed with clear-cell RCC (ccRCC) and 8 patients with non-ccRCC. Among ccRCC patients, 9 (47.4%) achieved a significant response with a maximum reduction of 30% or more in the size of the primary tumor from baseline within 4 months, while 3 (37.5%) out of 8 patients with non-ccRCC achieved a significant response. Shrinkage of the primary tumor correlated with the metastatic tumors in both ccRCC and non-ccRCC cases. Of note, 6 patients underwent CN and no viable tumor cells were detected in the surgical specimens of 3 patients whose primary tumors shrank by approximately 50%-60% with a reduction to 4 cm or less. Among ccRCC patients, the neutrophil-to-lymphocyte ratio and monocyte-to-lymphocyte ratio were slightly lower in responders than in non-responders (P = 0.0944 and P = 0.0691). The platelet-to-lymphocyte ratio was significantly lower in responders than in non-responder (P = 0.0391). CONCLUSIONS: Significant responses in primary tumors to nivolumab plus ipilimumab were observed in 50% of ccRCC patients, while responses varied among non-ccRCC patients. Inflammation markers may be predictive factors of treatment responses in primary tumors. Although further studies are needed, the present results suggest the importance of considering CN from radiological and pathological viewpoints.

    英語, 研究論文(学術雑誌), OBJECTIVES: During the past 2 decades, in order to improve perioperative and oncological outcomes, a minimally invasive approach, neoadjuvant chemotherapy (NAC), and an enhanced postoperative recovery program after surgery have been introduced into routine clinical practice of radical cystectomy (RC). Our aim was to examine the differences in clinical practice and postoperative complications after RC by comparing our previous and current cohorts. MATERIALS AND METHODS: A retrospective multi-institutional study. We collected all complications within 90 days after surgery between 2011 and 2017 (current cohort), and categorized them according to a standardized methodology. Then, we compared the outcomes with those in our previous study (previous cohort, 1997-2010). A multivariate logistic regression model was utilized to determine predictors of complications in the current cohort. RESULTS: A total of 838 patients were newly collected (current cohort), and 919 from the previous cohort were included in the subsequent analyses. In the current cohort, the rate of performing NAC was significantly higher (13% vs. 4%, respectively, P < 0.0001), and 26% (222/838) underwent laparoscopic RC (LRC, without robotic assistance: n = 210, with robotic assistance: n = 12). There was no significant difference in the overall complication [69% (580/838) vs. 68% (629/919), respectively, P = 0.7284] or major complication (Grades 3-5) [25% (211/838) vs. 22% (201/919), respectively, P = 0.1022] rates between the 2 cohorts. In both cohorts, the most frequent categories were infectious, gastrointestinal, wound-related, and genitourinary. In the current cohort, the performance status (odds ratio, OR = 2.11, P = 0.0013) and operative time (OR = 1.003, P = 0.0016) remained significant predictors of major complications. NAC was not associated with any or major complications. CONCLUSIONS: Surgical complications related to RC still remain significant problems, despite the recent improvements in surgical techniques and perioperative care. NAC did not increase the complications.

    英語, Introduction: We report a rare case of primary renal leiomyosarcoma with a tumor thrombus in the inferior vena cava. Case presentation: A 54-year-old woman presented with right flank pain and abdominal distension. Physical examination findings were unremarkable. Abdominal computed tomography revealed a heterogeneously enhancing right solid renal mass with a thrombus in the renal vein extending into the inferior vena cava. Magnetic resonance imaging demonstrated a renal tumor with a thrombus about 4 cm below the hepatic vein. Chest computed tomography and bone scintigraphy were negative. The patient underwent right radical nephrectomy and vena cava thrombectomy. Histophathologic evaluation of the resected tumor confirmed the diagnosis of leiomyosarcoma. She underwent no adjuvant therapy. Seven months after surgery, the patient died following a 2-month history of multiple pulmonary and hepatic metastases. Conclusion: This report highlights the importance of considering the possibility of renal leiomyosarcoma invasion to the inferior vena cava, similar to renal cell carcinoma.

    英語, 研究論文(学術雑誌), OBJECTIVES: We examined the outcomes of eight weekly bacillus Calmette-Guérin induction therapy after second transurethral resection, and investigated risk factors for intravesical recurrence or disease progression in high-risk non-muscle-invasive bladder cancer patients. METHODS: This retrospective study included 146 high-risk non-muscle-invasive bladder cancer patients who received eight weekly bacillus Calmette-Guérin instillations without a maintenance schedule between 2000 and 2019. Intravesical recurrence-free and progression-free survival rates were evaluated using the Kaplan-Meier method. The Cox proportional hazards model was used to identify risk factors. RESULTS: Pathological T staging in the first transurethral resection was pTa in 56 patients (38.4%), pT1 in 75 (51.4%) and primary carcinoma in situ in 15 (10.2%). A total of 109 (83.2%) with pTa-1 disease underwent second transurethral resection before bacillus Calmette-Guérin induction therapy, and residual disease was detected in 54 (49.5%). The completion rate of eight instillations was 82.2%. The 2- and 5-year intravesical recurrence-free survival rates were 80.7% and 75.2%, whereas the 2- and 5-year progression-free survival rates were 85.7% and 82.0%. Recurrent tumors (hazard ratio 6.5830, P = 0.0007) and residual tumors at the second transurethral resection (hazard ratio 4.0337, P = 0.0021) were risk factors for intravesical recurrence. Multiple tumors (hazard ratio 5.8056, P = 0.0302), pT1 disease (hazard ratio 3.7351, P = 0.0447) and residual tumors at second transurethral resection (hazard ratio 3.2552, P = 0.0448) were associated with disease progression. CONCLUSIONS: Accurate disease staging and disease elimination by second transurethral resection followed by eight weekly bacillus Calmette-Guérin instillations achieved good disease control. Our protocol (without a maintenance schedule) after thorough surgical resection has potential as a treatment option in the current bacillus Calmette-Guérin shortage.

    英語, 研究論文(学術雑誌), BACKGROUND: This study aimed to evaluate the pathological findings and oncological outcomes of deferred radical prostatectomy in patients who initially elected for active surveillance in a Japanese cohort. METHODS: We retrospectively analyzed data collected from a multi-institutional prospective observational cohort of the Prostate Cancer Research International: Active Surveillance-JAPAN study between January 2010 and September 2020. Triggers for radical prostatectomy were disease progression based on pathological findings of repeat biopsy and patients' request. The primary end point was evaluation of prostate-specific antigen recurrence-free survival. Secondary end points were overall survival and comparison of pathological and oncological outcomes between patients stratified into immediate or late radical prostatectomy group by time to radical prostatectomy. RESULTS: Overall, 162 patients (15.7%) with prostate cancer underwent initial active surveillance followed by radical prostatectomy. The median time to radical prostatectomy was 18 months (interquartile range 14-43.3), and the median postoperative follow-up was 32 months (interquartile range 14-57.5). Prostate-specific antigen recurrence was observed in eight patients (4.9%). The 3-year prostate-specific antigen recurrence-free survival rate was 96.9%. The 5-year overall survival rate was 100%; however, one patient died of another cause. There were no significant differences in pathological findings between immediate and late radical prostatectomy groups. No significant difference in prostate-specific antigen recurrence-free survival was found between the two groups (log-rank p = 0.34). CONCLUSIONS: Radical prostatectomy after active surveillance, as an initial treatment option, does not lead to loss of curative chances in Japanese patients with early-stage prostate cancer in the short follow-up period.

    英語, Introduction: Thyroid storm is a rare life-threating condition. We report a case of thyroid storm after radical nephrectomy for renal cell carcinoma with inferior vena cava tumor thrombus. Case presentation: A 76-year-old man with a left renal tumor and tumor thrombus extending into the inferior vena cava underwent left radical nephrectomy and thrombectomy. After the surgery, his postoperative course rapidly deteriorated, including central nervous system disturbance, fever, tachycardia, congestive heart failure, and hepatic manifestation. Thyroid function test revealed perioperative hyperthyroidism. Corticosteroids and inorganic iodide improved his condition, suggesting that he developed thyroid storm after surgery. He was discharged 5 months after surgery and has been free from disease recurrence for more than 2 years. Conclusion: Thyroid storm after surgery is rare. However, this postoperative complication is important because it is fatal if not diagnosed and treated properly.

    英語, 研究論文(学術雑誌), BACKGROUND: Our aim was to characterize the motions of multiple laparoscopic surgical instruments among participants with different levels of surgical experience in a series of wet-lab training drills, in which participants need to perform a range of surgical procedures including grasping tissue, tissue traction and dissection, applying a Hem-o-lok clip, and suturing/knotting, and digitize the level of surgical competency. METHODS: Participants performed tissue dissection around the aorta, dividing encountered vessels after applying a Hem-o-lok (Task 1), and renal parenchymal closure (Task 2: suturing, Task 3: suturing and knot-tying), using swine cadaveric organs placed in a box trainer under a motion capture (Mocap) system. Motion-related metrics were compared according to participants' level of surgical experience (experts: 50 ≤ laparoscopic surgeries, intermediates: 10-49, novices: 0-9), using the Kruskal-Wallis test, and significant metrics were subjected to principal component analysis (PCA). RESULTS: A total of 15 experts, 12 intermediates, and 18 novices participated in the training. In Task 1, a shorter path length and faster velocity/acceleration/jerk were observed using both scissors and a Hem-o-lok applier in the experts, and Hem-o-lok-related metrics markedly contributed to the 1st principal component on PCA analysis, followed by scissors-related metrics. Higher-level skills including a shorter path length and faster velocity were observed in both hands of the experts also in tasks 2 and 3. Sub-analysis showed that, in experts with 100 ≤  cases, scissors moved more frequently in the "close zone (0  ≤ to < 2.0 cm from aorta)" than those with 50-99 cases. CONCLUSION: Our novel Mocap system recognized significant differences in several metrics in multiple instruments according to the level of surgical experience. "Applying a Hem-o-lok clip on a pedicle" strongly reflected the level of surgical experience, and zone-metrics may be a promising tool to assess surgical expertise. Our next challenge is to give completely objective feedback to trainees on-site in the wet-lab.

    英語, 研究論文(学術雑誌), BACKGROUND: There is no useful predictive marker for reclassification on active surveillance. Thus, we aimed to investigate thresholds of [-2] proPSA (p2PSA)-related parameters to predict reclassification of the first-year protocol biopsy (1-year PBx) and evaluate the influence of clinical decision-making. METHODS: This was an observational, prospective cohort study conducted at 19 Japanese institutes. The inclusion criteria included clinical stage T1c/T2, prostate-specific antigen (PSA) levels ≤10 ng/mL, PSA density <0.2 ng/ml/cc, one or two positive biopsy cores, and Gleason score (GS) ≤6 (GS ≦7 for patients aged ≥70 years) at diagnostic biopsy. All participants were required to receive a blood-sampling test on a protocol visit at inclusion and at the 1-year PBx. PSA and PSA isoforms (free PSA, p2PSA) were measured, and parameters (%free PSA, %p2PSA, phi) were calculated. Multivariable logistic regression models were used to predict the reclassification risk. To assess the predictive power and thresholds for reclassification, we plotted Receiver Operating Characteristic (ROC) curves. Decision curve analysis (DCA) was used to evaluate the variables that yielded a net clinical benefit. RESULTS: A total of 135 patients were included, and 36 patients were reclassified on the 1-year PBx. Multivariate analyses showed that %p2PSA and phi at inclusion and p2PSA, %p2PSA, and phi before the 1-year PBx were significant predictors of reclassification at the 1-year PBx. The ROC analysis showed an optimal cutoff point, sensitivity, and specificity of %p2PSA and phi before the 1-year PBx of 1.64, 86%, 49% and 35.92, 89%, 47%, respectively. The DCA showed that phi before the 1-year PBx had the highest net benefit. The study limitation was its single-arm observational design. CONCLUSIONS: %p2PSA and phi before the 1-year PBx had a good prediction power. phi is the most useful indicator for clinical decision-making on active surveillance. TRIAL REGISTRATION: This study is registered atthe Japan Trial Register with ID UMIN000009876 ( https://upload.umin.ac.jp/cgi-open-bin/ctr_e/ctr_view.cgi?recptno=R000011573 ).

    英語, 研究論文(学術雑誌), OBJECTIVES: This study aimed to evaluate how health-related quality of life (HRQOL) is related to repeat protocol biopsy compliance. MATERIALS AND METHODS: We conducted a retrospective analysis using data from a prospective cohort in the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study between January 2010 and August 2019. We used the Short Form 8 Health Survey (SF-8), as patient-reported outcomes, to assess HRQOL at AS enrollment and the first year of the protocol. The physical component summary (PCS) and mental component summary (MCS) were calculated from SF-8 questionnaires. The primary outcome was the evaluation of the association of HRQOL at enrollment on the first repeat biopsy compliance. The secondary outcome was the comparison of SF-8 scores during AS, stratified by repeat protocol biopsy compliance. RESULTS: Of 805 patients who proceeded to the first year of the protocol, the non-compliance rate was 15% (121 patients). In the adjusted model, lower MCS at enrollment was significantly associated with the first repeat protocol biopsy non-compliance (odds ratio [OR], 2.134; 95% confidence interval [CI], 1.031-4.42; P = 0.041) but not in lower PCS (OR, 0.667; 95% CI, 0.294-1.514; P = 0.333). All subscales of SF-8 were lower in the non-compliance group than in the compliance group at any point. MCS in the non-compliance group improved over time from the time of AS enrollment (2.34 increased, P = 0.152). CONCLUSION: Our data suggest that lower MCS at AS enrollment using patient-reported outcomes was negatively associated with the first repeat protocol biopsy compliance. Our study may support the availability of a simple questionnaire to extract non-compliance.

    英語, 研究論文(学術雑誌), Objectives: The purpose of this study is to investigate whether verbal instructions are sufficient for bladder volume (BV) control not to deteriorate prostate position reproducibility in image-guided spot scanning proton therapy (SSPT) for localized prostate cancer.

    Methods: A total of 268 treatment sessions in 12 consecutive prostate cancer patients who were treated with image-guided SSPT with fiducial markers were retrospectively analyzed. In addition to strict rectal volume control procedures, simple verbal instructions to void urine one hour before the treatment were used here. The BV was measured by a Bladder Scan just before the treatment, and the prostate motion was measured by intraprostatic fiducial markers and two sets of X-ray fluoroscopy images. The correlation between the BV change and prostate motion was assessed by linear mixed-effects models and systematic and random errors according to the reproducibility of the BV.

    Results: The mean absolute BV change during treatment was from −98.7 to 86.3 ml (median 7.1 ml). The mean absolute prostate motion of the patients in the left-right direction was −1.46 to 1.85 mm; in the cranial-caudal direction it was −6.10 to 3.65 mm, and in the anteroposterior direction −1.90 to 5.23 mm. There was no significant relationship between the BV change and prostate motion during SSPT. The early and late genitourinary and gastrointestinal toxicity was minimal with a minimum follow up of 4.57 years.

    Conclusions: Simple verbal instructions about urination was suggested to be sufficient to control the BV not to impact on the prostate motion and clinical outcomes in image-guided SSPT. Careful attention to BV change is still needed when the seminal vesicle is to be treated.

    Advances in knowledge: Our data demonstrated that there was no apparent relationship between BV changes and prostate position reproducibility and simple verbal instruction about urination could be sufficient for image-guided SSPT.

    英語, A woman with a diagnosis of tuberous sclerosis complex (TSC) presented with TSC2 gene mutation and various manifestations, including epilepsy, renal angiomyolipomas (AML), and pathologically confirmed multifocal micronodular pneumocyte hyperplasia (MMPH). With oral administration of everolimus, a mammalian target of rapamycin (mTOR) inhibitor, MMPH and AML were markedly reduced. Further, after starting treatment with everolimus, serum levels of surfactant protein (SP)-A and SP-D, which reflect type II pneumocyte hyperplasia, decreased to the normal range. At the time of writing of this manuscript, 6 years after starting everolimus, MMPH lesions did not relapse and SP-A/D remained the low levels. This is the first case of everolimus efficacy shown for histologically confirmed MMPH in genetically determined TSC patient, with time course of serum SP-A and SP-D.

    英語, 研究論文(学術雑誌), INTRODUCTION: The aim of this study is to characterize health related quality of life (HRQOL) in Japanese patients after bladder cancer surgery and to perform cross-cultural comparison between Japanese and American patients.METHODS: Firstly, we cross-sectionally assessed HRQOL of 371 patients in Japan using the Bladder Cancer Index (BCI- Japanese). HRQOL of the four groups of patients (native bladder without intravesical therapy, native bladder with intravesical therapy, cystectomy with ileal conduit, and cystectomy with neobladder) were assessed. Secondly, we compared the Japanese with the American cohort (n = 315) from the original BCI paper. After adjusting for age and gender, the differences in each BCI subdomain score was analyzed.RESULTS: Among Japanese patients, the urinary domain function score was significantly lower among the cystectomy with neobladder group, compared to the cystectomy with ileal conduit group (p < 0. 01). Despite this, the urinary bother was comparable between the two groups. Although there were apparent differences between Japanese and American patients, there were few differences in Urinary and Bowel HRQOL. In three of the four treatment groups (other than native bladder with intravesical therapy), Japanese patients were more likely than Americans to report poor sexual function (p < 0.05). However, Japanese patients were less likely than Americans to be bothered by their lower sexual function, regardless of treatment (p <0.05).CONCLUSIONS: HRQOL outcomes following treatment of bladder cancer in Japan are comparable to those in the USA, except for sexual functioning and sexual bother. The BCI can be used for cross-cultural assessments of HRQOL in bladder cancer patients.

    英語, 研究論文(学術雑誌), INTRODUCTION: We validated a Japanese version of the Bladder Cancer Index (BCI) as a tool for measuring health-related quality of life (HRQOL) in bladder cancer patients treated with various surgical procedures. METHODS: The reliability and validity of the Japanese BCI were examined in 397 Japanese patients with bladder cancer via cross-sectional analysis. The patients simultaneously completed the Short Form (SF)-12, EQ-5D, and the Functional Assessment of Cancer Therapy-General and Bladder (FACT-G and FACT-BL). The differences in BCI subscales among various treatment groups were analyzed. RESULTS: This study involved 397 patients (301 males and 96 females), with a mean age of 70 years and a median disease duration of 29 months (IQR: 12-66 months). Of these patients, 221 underwent transurethral resection of a bladder tumor, and 176 patients underwent radical cystectomy (ileal conduit: 101 patients, ileal neobladder: 49, and ureterostomy: 26). Cronbach's alpha coefficient was ≥ 0.78 for all subscales, except the bowel bother subscale. Despite moderate correlations being detected between the function and bother score in urinary and bowel domains, the sexual function score was inversely correlated with the sexual bother score (r = - 0.19). A missing value percentage of > 15% was associated with old age (p < 0.05). The mean domain scores differed significantly among distinct clinically relevant treatment groups. CONCLUSIONS: Although revisions are needed to make it easier for elderly patients to comprehend, we confirmed the reliability and validity of the Japanese BCI. The Japanese BCI could be used for cross-cultural assessments of HRQOL in bladder cancer patients.

    英語, 研究論文(学術雑誌), BACKGROUND: Patients with favorable-risk prostate cancer on active surveillance (AS) are strictly followed for safer execution. Repeat protocol biopsy is essential for evaluating cancer aggressiveness. However, the acceptance rate of repeat biopsy is not high enough because of the burdens of biopsy. We assessed the impact of complications after the initial biopsy on repeat protocol biopsy at 1 year using data from the Prostate Cancer Research International: Active Surveillance (PRIAS)-JAPAN study. METHODS: We performed a retrospective analysis using a prospective cohort in the PRIAS-JAPAN study. Patients with favorable-risk prostate cancer (n = 856) who consented to participate in the PRIAS-JAPAN study from 2010 to 2018 were enrolled. Follow-up evaluations included regular prostate-specific antigen, digital rectal examination and biopsy. Rates of complications after biopsies and repeat protocol biopsy non-acceptance rate at 1 year were reported. Logistic regression analysis explored the association between the complications after the initial biopsy and repeat protocol biopsy non-acceptance. RESULTS: Altogether, 759 patients (88.7%) actually proceeded to protocol at 1 year. Repeat protocol biopsy non-acceptance rate at 1 year was 14.9%. Regarding complications after the initial biopsy, hematuria (p = 0.028) and pain (p < 0.001) rates were significantly higher in the repeat biopsy non-acceptance group, but infection (p = 0.056) and hematospermia (p = 0.337) rates were not different. On multivariate logistic regression analysis, pain was a significant predictor for repeat protocol biopsy non-acceptance (odds ratio 4.68, 95% confidence interval 1.864-11.75; p = 0.001). CONCLUSIONS: Pain at the initial biopsy negatively impacts patients' compliance with further protocol biopsies during AS.

    英語, 研究論文(学術雑誌), OBJECTIVES: This study investigated the relapse pattern and oncologic outcomes after laparoscopic nephroureterectomy with template-based lymph node dissection (LND) in patients with clinically node-negative (cN0) upper urinary tract urothelial carcinoma. The frequency of lymph node metastasis, including micrometastases, was also evaluated. METHODS AND MATERIALS: A total of 105 patients with cTa-3N0M0 upper urinary tract urothelial carcinoma were analyzed, all of whom underwent regional LND during laparoscopic nephroureterectomy. Of those patients, 96 (91%) underwent complete LND in accordance with an anatomical template-based rule. We collected patient characteristics, pathological data, and follow-up data from medical charts. Micrometastases were assessed by pan-cytokeratin immunohistochemistry. Nonurothelial recurrence-free survival and cancer-specific survival were estimated using the Kaplan-Meier method. RESULTS: The median number of lymph nodes removed was 12 (range, 1-59). Lymph node metastasis was identified by routine pathological examination in 7 (7/105, 6.7%) patients. Pan-cytokeratin immunohistochemistry revealed micrometastases in 5 additional patients (pNmicro +: 5/105, 4.8%). Nonurothelial disease recurrence was observed in 21 (20%) patients at a median of 10 months (range: 1-33) after surgery. Distant metastasis was dominant (15/105, 14.3%), followed by locoregional recurrence (5/105, 4.8%) and both (1/105, 0.95%). The 5-year nonurothelial recurrence-free survival rates were 84.8% for pN0, 53.3% for pNmicro+, and 19.1% for pN+ (3-sample log-rank test, P < 0.0001). The 5-year cancer-specific survival rates were 95.0% for pN0, 53.3% for pNmicro+, and 23.8% for pN+ (P < 0.0001). CONCLUSIONS: Our observation showed that template-based LND could contribute to precise disease staging and better local disease control probably by eliminating nodal disease, compared with previous studies. The survival impact and ideal management of pNmicro+ disease should be evaluated in a larger cohort.

    英語, 研究論文(学術雑誌), PURPOSE: To evaluate the health-related quality of life (HRQoL) of Japanese men on active surveillance (AS) in the Prostate cancer Research International Active Surveillance study in Japan (PRIAS-JAPAN). METHODS: Participants were included in the PRIAS-JAPAN HRQoL study between January 2010 and March 2016. Their general HRQoL was assessed using a validated Japanese version of the Short-Form 8 Health Survey (SF-8) at enrolment and annually thereafter until discontinuation of AS. The SF-8 mental component summary (MCS) and physical component summary (PCS) of men on AS were compared with scores of the general population (norm-based score [NBS]: 50) and MCS and PCS scores for men following AS were analysed over time. We tested whether MCS and PCS scores over time explained discontinuation of AS. RESULTS: Five hundred and twenty-five patients enrolled, and the median age at baseline was 68 years. At enrolment and after 1-, 2-, and 3-year follow-ups, the PCS and MCS scores were significantly higher than the NBS of the general Japanese population except for the median PCS at 3 years. We found that age at diagnosis and time on AS negatively affected the PCS score of men on AS, while every additional year on AS led to a 0.27 point increase in MCS scores. Neither PCS nor MCS were predictors for discontinuation of AS. CONCLUSION: Japanese men following an AS strategy for 3 years reported better HRQoL compared with the general population, indicating that monitoring Japanese low-risk prostate cancer patients can be an effective treatment strategy.

    英語, 研究論文(学術雑誌), OBJECTIVES: To develop a wet laboratory training model for learning core laparoscopic surgical skills and evaluating learners' competency level outside the operating room. METHODS: Participants completed three tasks (task 1: tissue dissection around the aorta; task 2: tissue dissection and division of the renal artery; task 3: renal parenchymal closure). Each performance was video recorded and subsequently evaluated by two experts, according to the Global Operative Assessment of Laparoscopic Skills and task-specific metrics that we developed (Assessment Sheet of Laparoscopic Skills in Wet Lab score). Mean scores were used for analyses. The subjective mental workload was also assessed (NASA Task Load Index). RESULTS: The 54 participants included 32 urologists, eight young trainees and 14 medical students. A total of 13 participants were categorized as experts (≥50 laparoscopic surgeries), eight as intermediates (10-49) and 33 as novices (0-9). There were significant differences in the Global Operative Assessment of Laparoscopic Skills and Assessment Sheet of Laparoscopic Skills in Wet Lab scores among the three groups in all three tasks. Higher NASA Task Load Index scores were observed in novices, and there were significant differences in tasks 1 (Kruskal-Wallis test, P = 0.0004) and 2 (P = 0.0002), and marginal differences in task 3 (P = 0.0745) among the three groups. CONCLUSIONS: Our training model has good construct validity, and differences in the NASA Task Load Index score reflect previous laparoscopic surgical experiences. Our findings show the ability to assess both laparoscopic surgical skills and mental workloads, which could help educators comprehend trainees' level outside the operating room. Given the decreasing opportunity to carry out pure laparoscopic surgeries because of the dissemination of robotic surgery, especially in urology, our model can offer practical training opportunities.

    英語, 研究論文(学術雑誌), Tumor endothelial cells (TEC) lining tumor blood vessels actively contribute to tumor progression and metastasis. In addition to tumor cells, TEC may develop drug resistance during cancer treatment, allowing the tumor cells to survive chemotherapy and metastasize. We previously reported that TECs resist paclitaxel treatment via upregulation of ABCB1. However, whether TEC phenotypes are altered by anticancer drugs remains to be clarified. Here, we show that ABCB1 expression increases after chemotherapy in urothelial carcinoma cases. The ratio of ABCB1-positive TEC before and after first-line chemotherapy in urothelial carcinoma tissues (n = 66) was analyzed by ABCB1 and CD31 immunostaining. In 42 cases (64%), this ratio increased after first-line chemotherapy. Chemotherapy elevated ABCB1 expression in endothelial cells by increasing tumor IL8 secretion. In clinical cases, ABCB1 expression in TEC correlated with IL8 expression in tumor cells after first-line chemotherapy, leading to poor prognosis. In vivo, the ABCB1 inhibitor combined with paclitaxel reduced tumor growth and metastasis compared with paclitaxel alone. Chemotherapy is suggested to cause inflammatory changes in tumors, inducing ABCB1 expression in TEC and conferring drug resistance. Overall, these findings indicate that TEC can survive during chemotherapy and provide a gateway for cancer metastasis. Targeting ABCB1 in TEC represents a novel strategy to overcome cancer drug resistance. SIGNIFICANCE: These findings show that inhibition of ABCB1 in tumor endothelial cells may improve clinical outcome, where ABCB1 expression contributes to drug resistance and metastasis following first-line chemotherapy.

    英語, 研究論文(学術雑誌), OBJECTIVE: Bladder-preserving trimodal therapy is recognized as a promising alternative treatment for muscle-invasive bladder cancer. We report the updated outcomes of muscle-invasive bladder cancer patients that were treated using our treatment protocol, which involves radiotherapy delivered with a real-time tumor-tracking radiotherapy system. METHODS: Thirty-eight patients who were diagnosed with T2-T4N0M0 bladder cancer between 1998 and 2016 and had clinically inoperable disease or refused to undergo surgery were enrolled. The treatment protocol included maximal transurethral resection followed by whole-bladder radiotherapy (40 Gy). Concurrent nedaplatin-based chemotherapy was administered to patients with adequate renal function. At the time of the first evaluation (via transurethral resection of the tumor bed), fiducial markers were endoscopically inserted into the bladder wall around the tumor. A boost of 25 Gy was administered using the real-time tumor-tracking radiotherapy system. The second evaluation (via transurethral resection of the tumor bed) was performed 6 months after the start of treatment. The Kaplan-Meier method and Cox hazards analysis were used to analyze overall survival and cancer-specific survival. RESULTS: The median duration of the follow-up period was 28 months (range: 3-161 months). The 5- and 10-year overall survival rates were 54.9 and 41.2%, respectively. Twenty-five (65.8%) and twenty (74.1%) patients had achieved complete responses to chemoradiation at the first and second evaluations, respectively. In univariate and multivariate analyses, performance status was found to be significantly associated with overall survival [P = 0.03, hazard ratio: 3.48, 95% confidence interval: 1.15-10.6] and cancer-specific survival [P = 0.02, hazard ratio: 4.57, 95% confidence interval: 1.32-16.9], and sex was shown to be significantly associated with cancer-specific survival [P = 0.03, hazard ratio: 3.07, 95% confidence interval: 1.09-8.30]. CONCLUSIONS: Our bladder-preserving trimodal therapy protocol, which involves the use of a real-time tumor-tracking radiotherapy system, produced an acceptable overall survival rate. This therapy is a reasonable alternative for patients that are medically unfit for or do not want to undergo cystectomy.

    英語, 研究論文(学術雑誌), OBJECTIVES: There is no consensus about the follow-up schedule after 5-year cancer-free periods. In this study, we aimed to elucidate the risk factors for the recurrence in patients with non-muscle-invasive bladder cancer who remained cancer free for more than 5 years. METHODS: Data from six Japanese institutions were retrospectively reviewed. Among the patients with non-muscle-invasive bladder cancer who were treated with transurethral resection of bladder tumor between 1990 and 2013, those who had no recurrence for more than 5 years were included in this study. The Kaplan-Meier method and Cox hazards model were used to estimate recurrence-free survival and to determine the pathologic and clinical factors affecting late recurrence. RESULTS: In total, 434 patients were enrolled in this study. Of these patients, 55 patients (12.7%) experienced late recurrence. The median follow-up time was 8.9 years (interquartile range 6.9-11.3 years). Prior history of bladder cancer before the most recent transurethral resection was a significant predictor for late recurrence (hazard ratio 1.99 [95% confidence interval 1.13-3.47], P = 0.019), although other clinical factors including tumor grade, pathologic stage, tumor multiplicity, and current risk classification systems were not associated with late recurrence. CONCLUSIONS: Late recurrence after a long tumor-free period is not rare and it was not predicted by current risk classification systems. Only prior history of bladder cancer was a significant predictor for late recurrence in this study.

    英語, 研究論文(学術雑誌), OBJECTIVE: To clarify the prognostic impact of local radiotherapy on metastatic urothelial carcinoma patients treated by systemic chemotherapy. METHODS: Of the 228 metastatic urothelial carcinoma patients treated with systemic chemotherapy, 97 received radiotherapy mainly to metastatic sites. In patients for whom the purpose of radiotherapy was not specified, more than 50 Gy irradiation was considered to be for disease consolidation for survival analysis, while less than 50 Gy was categorized as palliation. According to the Kaplan-Meier method, we analysed overall survival from the initiation of treatment for metastatic urothelial carcinoma until death or the last follow-up, using the log-rank test to assess the significance of differences. The Cox model was applied for prognostic factor analysis. RESULTS: Overall, there was no significant difference in survival between patients with and those without radiotherapy (P = 0.1532). When analysing the patients undergoing consolidative radiotherapy separately, these 25 patients showed significantly longer survival than the 72 patients with palliative radiotherapy (P = 0.0047), with a 3-year overall survival of 43.3%. Of the present cohort, 22 underwent metastasectomy for disease consolidation, and there was no overlapping case between the metastasectomy cohort and cohort receiving consolidative radiotherapy. After controlling for four independent prognostic factors (sex, performance status, haemoglobin level and number of organs with metastasis) in our previous study, radiotherapy for disease consolidation showed a marginal value (hazard ratio = 0.666, P = 0.0966), while metastasectomy remained significant (hazard ratio = 0.358, P = 0.0006). CONCLUSIONS: In the selected patients, long-term disease control could be achieved after consolidative radiotherapy for metastatic urothelial carcinoma disease. Our observations suggest that local ablative therapy (surgery or radiotherapy) could facilitate long-term disease control. However, the treatment decision should be individualized because of the lack of randomized control trials.

    英語, 研究論文(学術雑誌), Background: Virtual reality simulators allow trainees to perform repeated practice and provide objective dexterity metrics regarding their performance, which means that virtual reality-based surgical training is becoming a vital part of initial learning of basic laparoscopic surgical skills. However, its educational role in learning advanced procedures remains undetermined. We evaluated the validity of the laparoscopic radical nephrectomy module of the LapVision virtual reality simulator. Methods: Urologists, medical students, and a junior resident voluntarily participated in the present study, and they performed training with a laparoscopic left radical nephrectomy module. For construct validation, dexterity metrics calculated in the simulator and the mean score of Global Operative Assessment of Laparoscopic Skills evaluated by 2 experts' video review were compared according to the certification of Japanese Endoscopic Surgical Skill Qualification or previous surgical experience. Results: Ten experts (≥ 50 laparoscopic surgeries), 9 intermediates (11-49), and 14 novices (0-10) voluntarily participated in the present study. Regarding the construct validity, there was a significant difference in the total number of errors, blood loss, and Global Operative Assessment of Laparoscopic Skills score among the groups for both the Endoscopic Surgical Skill Qualification status and previous surgical experience. Conclusion: The present study demonstrated good construct validity for the LapVision nephrectomy module. Furthermore, global skill assessment was possible by experts' reviews, which indicates the usefulness of the virtual reality procedural module as a skill assessment tool. Virtual reality-based procedural simulation has marked potential to become a vital part of integrated laparoscopic training programs.

    日本語, 研究論文(学術雑誌), Left polyorchidism was found in a 2-month-old boy with a left scrotal mass. As he was asymptomatic and all testes were in the scrotum, he was conservatively followed up. At 17 years of age, he presented with left acute scrotum due to testicular torsion of the left supernumerary testis. Counterclockwise 720-degree rotation of the left supernumerary testis was noted during emergency surgery, and orchidopexy of the 3 testes (2 left testes and 1 right testis) was performed. Biopsy of the left supernumerary testis demonstrated spermatogenesis and no malignancy. One and a half years after surgery, all testes were viable without atrophy.Polyorchidism is a rare condition and there is no consensus on the management of asymptomatic cases detected early in life. The position of the supernumerary testis (intrascrotal or extrascrotal) is important when deciding the management strategy because of the risk of malignancy. If conservative management is selected initially, elective surgery, such as prophylactic orchiectomy or orchidopexy, may be needed because of the risk of malignancy and torsion.

    英語, A 66-year-old man was referred to our hospital for an incidentally detected 40-mm mass located at the inter-aortocaval area around the renal hilum. Positron emission tomography CT revealed high accumulation (SUVmax 12.382) without distant metastasis. Bilateral testes were normal by ultrasonography and physical examination, but the serum AFP level was increased to 1161 ng/mL. The pathology based on trans-duodenal needle biopsy demonstrated a yolk sac tumor; therefore, we diagnosed him with retroperitoneal primary germ cell tumor. Due to old age, the potential toxicity of systemic chemotherapy, and no significant signs of invasion to adjacent organs, we performed surgical resection. Although the AFP level decreased to 13.2 ng/mL postoperatively, it increased to 553 ng/mL 2 months after surgery without clinical recurrence on imaging studies. Four cycles of a VIP regimen (VP-16, ifosfamide, and CDDP) were performed, and the AFP level normalized to 2.4 ng/mL. The patient is now disease-free 1 year and 6 months after surgery.

    英語, 研究論文(学術雑誌), PURPOSE: To determine the best method to contour the planning organ at risk volume (PRV) for the urethra, this study aimed to investigate the displacement of a Foley catheter in the urethra with a soft and thin guide-wire. METHODS: For each patient, the study used two sets of computed tomography (CT) images for radiation treatment planning (RT-CT): (1) set with a Foley urethral catheter (4.0 mm diameter) plus a guide-wire (0.46 mm diameter) in the first RT-CT and (2) set with a guide-wire alone in the second CT recorded 2 min after the first RT-CT. Using three fiducial markers in the prostate for image fusion, the displacement between the catheter and the guide-wire in the prostatic urethra was calculated. In 155 consecutive patients treated between 2011 and 2017, 5531 slices of RT-CT were evaluated. RESULTS: Assuming that ≥3.0 mm of difference between the catheter and the guide-wire position was a significant displacement, the urethra with the catheter was displaced significantly from the urethra with the guide-wire alone in > 20% of the RT-CT slices in 23.2% (36/155) of the patients. The number of patients who showed ≥3.0 mm anterior displacement with the catheter in ≥20% RT-CT slices was significantly larger at the superior segment (38/155) than at the middle (14/155) and inferior segments (18/155) of the prostatic urethra (p < 0.0167). CONCLUSIONS: The urethral position with a Foley catheter is different from the urethral position with a thin and soft guide-wire in a significant proportion of the patients. This should be taken into account for the PRV of the urethra to ensure precise radiotherapy such as in urethra-sparing radiotherapy.

    日本語, 研究論文(学術雑誌), Radical cystectomy (RC) is the gold standard for managing muscle-invasive and high-risknon-muscleinvasive bladder cancer, but is accompanied by non-negligible operative risk. The aim of this study is to identify preoperative variables to predict major perioperative complications after RC and to develop a nomogram using the cohort from multiple institutions in Japan. We retrospectively reviewed 668 patients who underwent open RC with ileal conduit or neobladder at Hokkaido University hospital and 20 affiliated institutions between 1997 and 2010. Complications occurring within 90 days of surgery were graded using modified Clavien classification system. We defined modified Clavien grade 3 or more as major complications and performed univariate and multivariate logistic regression analyses. Predictive accuracy of the nomogram was evaluated with the area under the receiver operating characteristics curve (AUC). A total of 528 men and 140 women were included in this study. There were a total of 160/668 patients (24%) with major perioperative complications. A multivariate model identified gender (OR : 1. 63, p=0. 04), cardiovascular comorbidity (OR : 1.48, p=0.03) and simultaneous nephroureterectomy (OR : 2.81, p=0. 01) as independent predictors. Using these 3 variables, a nomogram was developed with the AUC of 0.58. Predictive performance of our nomogram showed only fair performance ; but at least, we identified male, cardiovascular comorbidity and simultaneous nephroureterectomy as independent predictors of perioperative major complications.

    英語, 研究論文(学術雑誌), Purpose: Robot-assisted laparoscopic radical prostatectomy (RARP) requires a steep head-down tilt and pneumoperitoneum, which may cause an increase in cerebral blood volume (CBV). With a new near-infrared time-resolved spectroscopy device, the tNIRS-1, we can measure the absolute value of the cerebral hemoglobin concentration and hence calculate CBV and cerebral oxygen saturation (rSO2). Using this device, we evaluated the time course of CBV during surgery and also evaluated the changes in rSO2 simultaneously. Materials and Methods: We performed a prospective observational study of 21 patients scheduled for RARP. We evaluated CBV and rSO2 by using the tNIRS-1 at 10 time points during surgery. Results: The CBV was 2.92 ± 0.38 mL ·100 g-1 after the end of anesthetic preparation. It significantly increased to 3.05 ± 0.44 mL ·100 g-1 after the head-down tilt and was around 3.1 mL ·100 g-1 until 120 minutes after the head-down tilt. However, just before the return to the horizontal position, it decreased to 2.93 ± 0.46 mL ·100 g-1 and then decreased more after the return to the horizontal position. Changes in rSO2 over time were within only 3%, and no significant differences from the control value were observed. Conclusions: The increase in CBV was <10% despite the steep head-down tilt and pneumoperitoneum, and it was compensated for at around the end of surgery. Clinically significant changes in rSO2 were not observed during the surgery.

    英語, 研究論文(学術雑誌), Locally advanced and metastatic invasive bladder cancer (BC) has a poor prognosis, and no advanced therapies beyond cisplatin-based combination chemotherapy have been developed. Therefore, it is an urgent issue to elucidate the underlying mechanisms of tumor progression and metastasis of invasive BC for the development of new therapeutic strategies. Here, we clarified a novel role of exosomes containing ErbB2 and CRK in a formation of premetastatic niches and subsequent metastases. CRK adaptors were overexpressed in invasive UM-UC-3 BC cells. In an orthotopic xenograft model, metastases to lung, liver, and bone of UM-UC-3 cells were completely abolished by CRK elimination. Mass spectrometry analysis identified that ErbB2 was contained in UM-UC-3-derived exosomes in a CRK-dependent manner; the exosomes significantly increased proliferation and invasion properties of low-grade 5637 BC cells and HUVECs through FAK and PI3K/AKT signaling pathways. In athymic mice educated with UM-UC-3-derived exosomes, i.v. implanted UM-UC-3 cells were trapped with surrounding PKH67-labeled exosomes in lung and led to development of lung metastasis with disordered vascular proliferation. In contrast, exosomes derived from CRK-depleted BC cells failed to induce these malignant features. Taken together, we showed that CRK adaptors elevated the expression of ErbB2/3 in BC cells, and these tyrosine kinase/adaptor units were transferred from host BC cells to metastatic recipient cells by exosomes, leading to vascular leakiness and proliferation and contributing to the formation of distant metastasis. Thus, CRK intervention with ErbB2/3 blockade might be a potent therapeutic strategy for patients with ErbB2 overexpressing advanced and metastatic BC.

    英語, 研究論文(学術雑誌), OBJECTIVE: To evaluate the association between the RENAL nephrometry score (RNS) and tumor proliferative activity assessed by immunohistochemistry in patients with localized renal cell carcinoma. METHODS: The current study included 145 pathological T1 (pT1) clear cell renal cell carcinomas (ccRCC). Tumor proliferative activity was assessed with the Ki67 index and microvessel density (MVD). RNS was retrospectively assessed in the present study. We divided patients into 3 groups according to RNS (RNS 4-6: low-complexity, 7-9: moderate complexity, and 10-12: high-complexity tumors) and compared the Ki67 index as well as MVD among the 3 groups. The association between the Ki67index/MVD and each component (R, E, N, A, L, h) was also evaluated. RESULTS: There were 56 low, 84 moderate, and 5 high-complexity tumors. The median Ki67 index of all tumors was 5.34% (interquartile range: 3.28-8.57). The median Ki67 index of low, moderate, and high-complexity tumors was 3.97%, 6.39%, and 11.27%, respectively, with a significant difference among the 3 groups (Kruskal-Wallis test, P = 0.0004). On the other hand, the median MVD of low, moderate, and high-complexity tumors was 14.11%, 14.42%, and 21.22%, respectively, and there were no significant differences among the 3 groups. In terms of each RNS component, there were significant differences in the Ki67 index among the 3 groups in N (P = 0.0101) and L (P = 0.0280) components, respectively. CONCLUSIONS: The revealed association between RNS and the Ki67 index in pT1 clear cell renal cell carcinomas further supports the previous findings that the anatomy of renal cell carcinoma is associated with the malignant potential of localized clear cell renal cell carcinoma, which may provide additional information for treatment decision.

    英語, 研究論文(学術雑誌), Objective: To assess the number of lymph nodes removed as a surrogate marker of the extent of lymph node dissection, and compare survival outcomes between laparoscopic radical nephroureterectomy (LRNU) and open radical nephroureterectomy (ORNU) in patients undergoing standardized lymph node dissection. Methods: We retrospectively analyzed the data of 214 cTanyN0M0 patients undergoing radical NU with regional lymph node dissection according to the tumor location. The Kaplan-Meier method and Cox hazards model were utilized for survival analyses, including recurrence-free survival (RFS), cancer-specific survival (CSS) and overall survival (OS). Results: A total of 114 patients underwent LRNU and 100 underwent ORNU. There was no significant difference in the pT stage, pN stage, or tumor grade, but distal ureteral tumors were more frequent in the LRNU group. The number of lymph nodes removed did not differ between the two groups [LRNU: 12 (median), ORNU: 11.5, P = 0.3852]. Lymph node metastasis was pathologically identified in 19 patients (8.9%). The 5-year RFS (ORNU: 71.7%, LRNU: 74%, P = 0.7829), CSS (77.8 and, 80%, P = 0.8441) and OS (72.8, and 75.9%, P = 0.3456) did not differ between the two groups. In the sub-analysis of pT3/4 patients (n = 83), there were no significant differences in RFS, CSS, or OS between the two groups, although Kaplan-Meier survival curves were slightly better for those receiving ORNU. In the multivariate model, LRNU was not significantly correlated with a poorer RFS, CSS or OS. Conclusion: Our data support the feasibility of lymph node dissection with a laparoscopic approach and the equivalent oncological outcome of LRNU compared with ORNU when regional lymph node dissection is performed. However, LRNU should be performed after careful patient selection for advanced disease.

    日本語, 研究論文(学術雑誌), Axitinib was approved for use in Japan as a salvage therapy for patients with metastatic renal cell carcinoma (RCC) in 2012. We retrospectively evaluated the cases of 32 RCC patients that were treated with Axitinib as a 2nd- or further-line therapy between November 2012 and March 2017. Overall survival (OS), progression-free survival (PFS), and adverse events were assessed. The median OS and PFS from the initiation of Axitinib were 29 and 11 months, respectively. Nineteen patients received Axitinib as a 2nd-line treatment, in whom the median OS and median PFS were 22 and 10 months, respectively, while the median OS and PFS were 29 and 15.5 months, respectively, amongthe 13 patients who received Axitinib as a 3rd- or further-line treatment, which suggested that Axitinib is effective in the 3rd-line and further-line settings. A Cox multivariate model revealed that bone metastasis was a significant adverse factor for OS. Common grade 3 or higher adverse events included hypertension (28%), diarrhea (7%), and proteinuria (7%). Although the present study demonstrated the efficacy and safety of salvage Axitinib treatment in patients who had recurrent disease after the initial systemic therapy, further large-scale studies should be warranted to make clear its clinical effectiveness in these patients.

    英語, 研究論文(学術雑誌), Objectives: The objective of the present study was to investigate the survival outcome and prognostic factors of metastatic urothelial carcinoma patients treated with second-line systemic chemotherapy in real-world clinical practice. Methods: Overall, 114 patients with metastatic urothelial carcinoma undergoing second-line systemic chemotherapy were included in this retrospective analysis. The dominant second-line chemotherapy was a paclitaxel-based combination regimen (60%, 68/114). We assessed the progression-free survival and overall survival times using the Kaplan-Meier method. The Cox proportional hazards model was applied to identify the factors affecting overall survival. Results: The median progression-free survival and overall survival times were 4 and 9 months, respectively. In the multivariate analysis, an Eastern Cooperative Oncology Group performance status score greater than 0 at presentation, C-reactive protein level ≧1 mg/dl and poor response to prior chemotherapy were adverse prognostic indicators. Patients with 0, 1, 2 and 3 of those risk factors had a median overall survival of 17, 12, 7 and 3 months, respectively. Conclusions: The Eastern Cooperative Oncology Group performance status at presentation, C-reactive protein level and response to prior chemotherapy were prognostic factors for metastatic urothelial carcinoma patients undergoing second-line chemotherapy. In the future, this information might help guide the choice of salvage treatment, such as second-line chemotherapy or immune checkpoint inhibitors, after the failure of first-line chemotherapy.

    英語, 研究論文(学術雑誌), Objective: To determine the characteristics of 90-day morbidity and mortality after radical cystectomy in Japanese octogenarians. Methods: A retrospective multi-institutional study. We reviewed the records of 834 patients treated by open radical cystectomy between 1997 and 2010. All complications within 90 days after surgery were sorted into the 11 categories proposed by the Memorial Sloan-Kettering Cancer Center and graded according to the modified Clavien-Dindo system. We compared the characteristics of complications between ≥80-year (n = 86) and <80-year (n = 748) groups. Multivariate regression models were used to determine the predictors of complications. Results: American Society of Anesthesiologists score III-IV was more frequent (14% vs. 6%, respectively, P < 0.0001), and ureterocutaneostomy was more frequently performed (30% vs. 21%, respectively, P = 0.0148) in the ≥80-year group compared with <80-year group. There were no significant differences in the rates of any complication, major (Grade 3-5) complication, or 90-day mortality between the two groups (≥80-year group: 70%, 21%, 3.5%, respectively, <80-year group: 68%, 22%, 2%, respectively). The ≥80-year group had fewer genitourinary complications (7% vs. 16%, respectively, P = 0.0131). Multivariate regression analyses revealed that bowel-using urinary diversion (P = 0.0031) and the operative time (P = 0.0269) were significant predictors of any grade of complications, and a male sex (P = 0.0167), annual cystectomy volume (P = 0.0284) and prior cardiovascular comorbidity (P = 0.0034) were significant predictors of major complications. Conclusions: In our experience, radical cystectomy in Japanese octogenarians caused similar perioperative comorbidities. Old age as a single criterion should not be used to abandon radical cystectomy; careful preoperative assessment is mandatory.

    英語, 研究論文(学術雑誌), AIM: To clarify prognostic factors of metatstatic urothelial carcinoma treated by systemic chemotherapy in real-world clinical practice in the Japanese population. MATERIALS AND METHODS: A total of 228 patients with metastatic urothelial carcinoma undergoing systemic chemotherapy between 2000 and 2013 were included in the present multi-institutional study. The gemcitabine plus cisplatin regimen was administered as first-line chemotherapy to 131 patients, whereas methotrexate, vinblastine, doxorubicin, and cisplatin or its modified regimen was given to 71 patients. Of the 228 patients, 119 received at least 2 different regimens and 22 underwent resection of metastases (metastasectomy). Multivariate survival analysis was performed using the Cox proportional hazards model. The characteristics included were age, sex, Eastern Cooperative Oncology Group performance status (PS), primary site, pathology of primary site, hemoglobin levels, lactate dehydrogenase levels, C-reactive protein levels, corrected calcium levels, estimated glomerular filtration rate levels, history of prior chemotherapy, metastatic sites, resection of primary site, number of metastatic organs, and metastasectomy. RESULTS: The median overall survival (OS) time was 17 months. On multivariate analysis, female sex, good Eastern Cooperative Oncology Group PS at presentation, hemoglobin level≥10g/dl, and single organ metastasis were significant independent predictors of prolonged OS. For the survival effect of metastasectomy, the median OS time of the 22 patients with metastasectomy was 53 months, which was significantly longer when compared with patients not undergoing metastasectomy (15mo). After adjustment for the 4 aforementioned prognostic factors, metastasectomy still remained significant (hazard ratio: 0.364, P = 0.0008). CONCLUSIONS: Female sex, more favorable PS at presentation, hemoglobin level>10g/dl, and single organ metastasis were favorable prognostic factors. In addition, metastasectomy was associated with long-term disease control.

    Current opinion in urology, 26, 6, 573, 80, 2016年11月, [査読有り], [国際誌]
    英語, 研究論文(学術雑誌), PURPOSE OF REVIEW: Since the development of systemic combination chemotherapy, postchemotherapy extirpation has been performed in selected patients mainly with locally advanced and/or initially unresectable bladder cancer, and, in very selected patients, surgical consolidation for visceral metastases has also been performed. The purpose of this article was to review and summarize the current evidence for the role of surgical consolidation in metastatic urothelial carcinoma. RECENT FINDINGS: The role of metastasectomy has not yet been examined in a randomized setting. In terms of locally advanced and/or node-positive bladder cancer, studies further support the benefit of surgical consolidation, especially after a favorable response to systemic chemotherapy. Regarding metastasectomy for visceral metastasis, recent evidence suggested that lung metastases (ideally small solitary lesions) are a good indication. SUMMARY: Patients with a good response to chemotherapy, limited nodal/pulmonary disease, and a favorable performance status are good candidates for surgical consolidation. Careful patient selection is mandatory.

    英語, 研究論文(学術雑誌), In treating bladder cancer, determining the molecular mechanisms of tumor invasion, metastasis, and drug resistance are urgent to improving long-term patient survival. One of the metabolic enzymes, aldo-keto reductase 1C1 (AKR1C1), plays an essential role in cancer invasion/metastasis and chemoresistance. In orthotopic xenograft models of a human bladder cancer cell line, UM-UC-3, metastatic sublines were established from tumors in the liver, lung, and bone. These cells possessed elevated levels of EMT-associated markers, such as Snail, Slug, or CD44, and exhibited enhanced invasion. By microarray analysis, AKR1C1 was found to be up-regulated in metastatic lesions, which was verified in metastatic human bladder cancer specimens. Decreased invasion caused by AKR1C1 knockdown suggests a novel role of AKR1C1 in cancer invasion, which is probably due to the regulation of Rac1, Src, or Akt. An inflammatory cytokine, interleukin-1β, was found to increase AKR1C1 in bladder cancer cell lines. One particular non-steroidal anti-inflammatory drug, flufenamic acid, antagonized AKR1C1 and decreased the cisplatin-resistance and invasion potential of metastatic sublines. These data uncover the crucial role of AKR1C1 in regulating both metastasis and drug resistance; as a result, AKR1C1 should be a potent molecular target in invasive bladder cancer treatment.

    英語, 研究論文(学術雑誌), BACKGROUND: To clarify the relationship between the probability of prostate cancer scaled using a 5-point Likert system and the biological characteristics of corresponding tumor foci. METHODS: The present study involved 44 patients undergoing 3.0-Tesla multiparametric MRI before laparoscopic radical prostatectomy. Tracing based on pathological and MRI findings was performed. The relationship between the probability of cancer scaled using the 5-point Likert system and the biological characteristics of corresponding tumor foci was evaluated. RESULTS: A total of 102 tumor foci were identified histologically from the 44 specimens. Of the 102 tumors, 55 were assigned a score based on MRI findings (score 1: n = 3; score 2: n = 3; score 3: n = 16; score 4: n = 11 score 5: n = 22), while 47 were not pointed out on MRI. The tracing study revealed that the proportion of >0.5 cm(3) tumors increased according to the upgrade of Likert scores (score 1 or 2: 33%; score 3: 68.8%; score 4 or 5: 90.9%, χ(2) test, p < 0.0001). The proportion with a Gleason score >7 also increased from scale 2 to scale 5 (scale 2: 0%; scale 3: 56.3%; scale 4: 72.7%; 5: 90.9%, χ(2) test, p = 0.0001). On using score 3 or higher as the threshold of cancer detection on MRI, the detection rate markedly improved if the tumor volume exceeded 0.5 cm(3) (<0.2 cm(3): 10.3%; 0.2-0.5 cm(3): 25%; 0.5-1.0 cm(3): 66.7%; 1.0 < cm(3): 92.1%). CONCLUSIONS: Each Likert scale favobably reflected the corresponding tumor's volume and Gleason score. Our observations show that "score 3 or higher" could be a useful threshold to predict clinically significant carcinoma when considering treatment options.

    英語, 研究論文(学術雑誌), OBJECTIVE: To investigate node-disease prevalence including micrometastases and its survival impact on bladder cancer patients. METHODS: A total of 60 patients participated in this study, in which extended lymph node dissection was carried out according to the prospective rule (below aortic bifurcation). Radical cystectomy and extended lymph node dissection were performed by open surgery (n = 23) or laparoscopically (n = 37). Perioperative, pathological and follow-up data were collected. Micrometastasis in lymph nodes was investigated by pan-cytokeratin immunohistochemistry. Recurrence-free survival was estimated with the Kaplan-Meier method. RESULTS: The median number of lymph nodes removed was 29 (range: 10-103) and there was no significant difference between the two groups (open group: median 30, laparoscopic group: median 29). Routine pathological examination revealed that 10 patients had lymph node metastases. Immunohistochemistry revealed micrometastases in four additional patients (pNmicro+), who had been diagnosed with pN0 on routine pathological examination. After excluding the three patients with pure nonurothelial carcinoma on the final pathology (small cell carcinoma: n = 2, adenocarcinoma: n = 1), 10 out of the 57 urothelial carcinoma patients (17.5%) had node metastasis, and an additional 4 out of the 47 pN0 patients (4/47, 8.5%) had micrometastasis. The 2-year recurrence-free survival rates divided by pN stage were 82.4% for pN0, 66.7% for pNmicro+ and 12.5% for pN+ (three-sample log-rank test, P < 0.0001). Three out of the four patients with pNmicro+ were disease free at the last follow-up. CONCLUSIONS: We confirmed under extended lymph node dissection that a substantial proportion of the patients had node metastasis (pN+: n = 10 and pNmicro+: n = 4), and the pN stage influenced patient survival. Our observations of micrometastasis yielded additional evidence for the potential survival benefit of extended lymphadenectomy by eliminating microdisease.

    英語, 研究論文(学術雑誌), We have previously reported that an adaptor protein CRK, including CRK-I and CRK-II, plays essential roles in the malignant potential of various aggressive human cancers, suggesting the validity of targeting CRK in molecular targeted therapy of a wide range of cancers. Nevertheless, the role of CRK in human bladder cancer with marked invasion, characterized by distant metastasis and poor prognosis, remains obscure. In the present study, immunohistochemistry indicated a striking enhancement of CRK-I/-II, but not CRK-like, in human bladder cancer tissues compared to normal urothelium. We established CRK-knockdown bladder cancer cells using 5637 and UM-UC-3, which showed a significant decline in cell migration, invasion, and proliferation. It is noteworthy that an elimination of CRK conferred suppressed phosphorylation of c-Met and the downstream scaffold protein Gab1 in a hepatocyte growth factor-dependent and -independent manner. In epithelial-mesenchymal transition-related molecules, E-cadherin was upregulated by CRK elimination, whereas N-cadherin, vimentin, and Zeb1 were downregulated. A similar effect was observed following treatment with c-Met inhibitor SU11274. Depletion of CRK significantly decreased cell proliferation of 5637 and UM-UC-3, consistent with reduced activity of ERK. An orthotopic xenograft model with bioluminescent imaging revealed that CRK knockdown significantly attenuated not only tumor volume but also the number of circulating tumor cells, resulted in a complete abrogation of metastasis. Taken together, this evidence uncovered essential roles of CRK in invasive bladder cancer through the hepatocyte growth factor/c-Met/CRK feedback loop for epithelial-mesenchymal transition induction. Thus, CRK might be a potent molecular target in bladder cancer, particularly for preventing metastasis, leading to the resolution of clinically longstanding critical issues.

    英語, 研究論文(学術雑誌), PURPOSE: To determine the appropriate template of regional lymph node dissection (LND) at the time of laparoscopic nephroureterectomy (LNU) for patients with clinically node- negative urothelial carcinoma of the upper urinary tract. PATIENTS AND METHODS: This prospective study included 45 patients undergoing LND with LNU in accordance with our prospective rules regarding the area of LND. Perioperative, pathologic, and follow-up data were collected. Micrometastasis in lymph nodes (LNs) was later evaluated by immunohistochemistry (IHC). Recurrence-free survival (RFS) was calculated with the Kaplan-Meier method. RESULTS: The median number of LNs removed was 14 (range 1-33). One patient with pT3 disease had node metastasis based on routine pathologic examination, and IHC revealed micrometastases in two additional patients (pT2 in one and pT3 in one). Therefore, 15% (3/20) of patients with ≥pT2 disease had node disease. After surgery, six patients experienced minor complications (Grade 1 or 2), and Grade 5 gastrointestinal bleeding after aspiration pneumonia developed in one elderly male patient on the 45th postoperative day, which was not considered to be associated with LND. At the last follow-up, lung metastasis developed in four patients (pT1 in one, pT2 in one, and pT3 in two), and presacral lymph node metastasis developed in one patient with a lower ureteral tumor (pT2), which was not included in our prospective template for a lower ureteral tumor. LN recurrence within/ near the LND area was not observed in patients with pelvic/upper ureteral carcinoma. The 2-year nonurothelial RFS rate was 84%. CONCLUSIONS: We consider that the present template represents regional LNs for patients with clinically node-negative pelvic/upper ureteral carcinoma, while presacral LNs may be incorporated into the regional LND template for patients with clinically node-negative lower ureteral carcinoma.

    英語, 研究論文(学術雑誌), Purpose: This study was to evaluate the effect of intraoperative continuous infusion of dexmedetomidine on intraocular pressure (IOP) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RALRP) in the steep Trendelenburg (ST).
    Materials and Methods: Sixty-eight patients were randomly divided into two groups. The dexmedetomidine group (Group D, n=34) received a continuous infusion of dexmedetomidine at a rate of 0.4 mu g kg(-1) hour(-1) from the induction of anesthesia until the end of the ST position, while the control group (Group C, n=34) received an equal volume of physiologic saline at the same rate under conventional general anesthesia with sevoflurane and remifentanil. IOP was measured at 11 predefined time points for all patients.
    Results: Significant differences in IOP were detected between the two groups by a linear mixed model analysis (p<0.001). The highest mean IOP was 19.9 +/- 5.0 mm Hg in Group D and 25.7 +/- 5.0 mm Hg in Group C; both were measured 60 minutes after the patients had been placed in the ST position. No significant between-group differences in ocular perfusion pressure, mean blood pressure, or heart rate were observed between the two groups. No ocular or other complications were noted.
    Conclusion: Intraoperative continuous infusion of dexmedetomidine may help alleviate IOP increase in patients undergoing RALRP in the ST position.

    英語, 研究論文(学術雑誌), BACKGROUND: Renal cell carcinoma (RCC) with rhabdoid features is a rare histology and exhibits clinically aggressive behavior. We report a case of a married couple in whom RCC with rhabdoid features concurrently occurred. The rarity of this event suggests that environmental factors may contribute to the etiology of RCC with rhabdoid features. CASE PRESENTATION: A 76-year-old Japanese woman was diagnosed with a hypervascular mass in the right kidney and tumor thrombus extending into the right atrium by enhanced computed tomography (CT). She underwent radical nephrectomy and tumor thrombectomy following systemic therapy with the tyrosine kinase inhibitor sunitinib. The histological evaluation denoted clear cell RCC with rhabdoid features. The patient died of cancer 12 months postoperatively. A 76-year-old man, her husband, presented with gross hematuria 2 weeks after his wife had undergone surgery. He had a long history of asbestos exposure. An abdominal CT scan revealed a hypervascular mass in the right kidney and tumor thrombus extending into the inferior vena cava. He also underwent radical nephrectomy and tumor thrombectomy. The histological evaluation also showed clear cell RCC with rhabdoid features. Bone metastasis occurred 12 months postoperatively, but he died of an unrelated cause 18 months after surgery. CONCLUSION: Concurrent occurrence of RCC with rhabdoid features may not to be coincidental. Although further studies are warranted, asbestos exposure may contribute to the etiology of clear cell RCC with rhabdoid features.

    英語, 研究論文(学術雑誌), OBJECTIVE: To determine the differences in the type, incidence, and severity of 90-day morbidity after radical cystectomy between two different methods of urinary diversion, ileal conduit and neobladder. METHODS: We carried out a retrospective multi-institutional study by reviewing the records of 668 patients treated with open radical cystectomy, and ileal conduit (n = 493) or neobladder substitution (n = 175) between 1997 and 2010. All complications within 90 days after surgery were divided into 11 specific categories as reported by the Memorial-Sloan Kettering Cancer Center, and graded according to the modified Clavien system. Type, incidence and severity of the 90-day morbidity between the two different types of urinary diversions were compared. RESULTS: There was no significant difference in the overall complication rates between the two groups (ileal conduit: 72% [353/493], neobladder: 74% [129/175], P = 0.5909), whereas the neobladder group had fewer major (grade 3 or more) complications (13 vs 20%, respectively, P = 0.0271). The neobladder group had more infectious complications (43 vs 31%, respectively, P = 0.0037), mainly as a result of urinary tract infection, whereas the ileal conduit group had more wound-related complications (24 vs 14%, respectively, P = 0.0068), mainly as a result of surgical site infection. The 90-day mortality rates were 1.1% (2/175) in the neobladder group and 1.6% (8/493) in the ileal conduit group (P = 0.6441). CONCLUSIONS: There was no significant difference in the overall complication rates between the two methods, and patients with neobladder had fewer major complications. The neobladder group had more infectious complications, whereas the ileal conduit group had more wound-related complications.

    英語, 研究論文(学術雑誌), OBJECTIVE: To evaluate the association between the RENAL nephrometry score and annual growth rates of renal masses presumed to be renal cell carcinoma. METHODS: The current study included 47 renal tumors followed up for at least 12 months, of which 26 tumors were found to be pathologically proven renal cell carcinomas. Annual tumor growth rates were calculated from changes in the maximal diameter on computed tomography, and RENAL nephrometry scores were recorded on initial imaging by two senior urologists. The associations between clinical characteristics including the RENAL nephrometry score and annual growth rates were analyzed using a linear regression model. RESULTS: The median tumor size at diagnosis was 1.7 cm (range 0.6-5.8). The median nephrometry score at diagnosis was 7 (range 4-10). Overall, the median tumor growth rate was 0.34 cm per year (range -0.19-2.0). Linear regression analysis showed that the annual tumor growth rate was associated with the RENAL nephrometry score (P < 0.0001), but it was independent of the age at diagnosis, sex and initial tumor size. In addition, the correlation between the RENAL nephrometry score and annual growth rate remained significant in the 26 pathologically proven renal cell carcinomas. CONCLUSIONS: The RENAL nephrometry score is associated with the annual growth rate of renal masses. Our findings further support the association between the RENAL nephrometry score and tumor biology.

    英語, 研究論文(学術雑誌), PURPOSE: To investigate changes in renal function after retroperitoneal laparoscopic partial nephrectomy (LPN) with renal hypothermia induced by ice-slush cooling. PATIENTS AND METHODS: Seventy-one patients undergoing retroperitoneal LPN with renal hypothermia were included. Perioperative outcomes were reviewed retrospectively. The total renal function was evaluated by an estimated glomerular filtration rate (eGFR) preoperatively and 6 months postoperatively in 69 patients. Split renal function (SRF) was also evaluated by 99mTc-mercaptoacetyltriglycine scintigraphy preoperatively and 6 months postoperatively in 61 patients. RESULTS: The median operative time was 246 minutes (range, 155-424). The median cold ischemic time, including the initial 15 minutes of hypothermia, was 57 minutes (range, 34-112). In the 21 patients whose renal temperature was monitored, median lowest renal temperature was 20.7°C (range, 12.1-27.6). The median baseline eGFR and 6-month postoperative eGFR were 77.2 mL/min/1.73 m(2) (range, 36.1-121.3) and 68.3 mL/min/1.73 m(2) (range, 33.2-103.4), and the median baseline SRF and 6-month postoperative SRF of the affected kidney were 49.3% (range, 40.3-57.6) and 40.7% (range, 13.8-54.5). Using multivariate analysis, the baseline eGFR (p<0.0001) and the ischemic time (p=0.0073) were associated with the 6-month postoperative eGFR, and the 6-month postoperative SRF was only associated with a baseline SRF (p=0.0185). CONCLUSIONS: Ice-slush cooling could provide renal hypothermia also under LPN. The decrease in renal function was small, whereas our ischemic time was longer than experts' warm ischemic series. These observations suggested the protective effect of our cooling methods against ischemic injury.

    日本語, 研究論文(学術雑誌), Patients undergoing radical prostatectomy at our hospital from January 1995 until March 2008 were subjected to limited lymphadenectomy involving only the obturator nerve lymph node. In contrast to published reports, of 488 biopsies, we encountered only three cases of lymph node metastasis. Therefore, starting in April 2008, we conducted a prospective study of limited versus extended lymphadenectomy, the latter involving the obturator fossa and internal iliac lymph nodes. One hundred patients undergoing radical prostatectomy from April 2008 until January 2010 were divided into two groups depending on whether they underwent extended lymphadenectomy (n=49) or limited lymphadenectomy (n=51). There were no significant differences in the patient background, estimated blood loss, or operation time between the two groups. Lymphnode metastases were not detected in either group. A significantly greater number of lymph nodes was obtained from the extended lymphadenectomy group (average 14.1) than from the limited lymphadenectomy group (average 8.3 ; p<0.01). Complications possibly attributable to lymphadenectomy included lymphocele in two patients in the limited group and one patient in the extended group. Extended lymphadenectomy was determined to be a safe procedure that provides the pathologist with a large sample size. None of the patients in either group harbored a detectable lymph node metastasis.

  • 【バイプレーヤーズ!転移性癌治療における外科治療の役割,徹底解明】(Part 1)薬物治療が進歩した今,転移性癌の原発巣切除は勧められるか!? 転移性尿路上皮癌の原発巣切除は勧められるか?

    転移性尿路上皮癌においても,症状緩和目的や,転移巣が全身化学療法でコントロールされている状況で原発巣切除が考慮される場合がある。主に所属リンパ節転移のみを認める症例では,全身化学療法が有効で,かつ原発巣と転移巣を含め完全切除が可能であった場合には長期生存が期待される。近年注目されている遠隔転移を有する症例での予後改善効果に関しては,転移性尿路上皮癌に関しては無作為化前向き試験で観察された結果ではない点を強調したい。その実施にあたって個々の症例ごとにそのベネフィット・リスクを十分吟味する必要がある。(著者抄録), 医学図書出版(株), 日本語

    症例は54歳女性,原疾患不明の慢性腎不全に対して献腎移植を施行され腎機能は安定していた.移植後6年で膀胱刺激症状を契機に膀胱右側の筋層浸潤性膀胱癌が判明し肺転移も伴っていた.StageIV膀胱癌として免疫抑制剤を減量しゲムシタビン・シスプラチン療法を開始したところ,4コース後に転移巣が消失した.新規病変を認めなかったため開放手術にて右腎尿管膀胱全摘術および回腸導管造設を行った.摘出標本で左尿管断端に上皮内癌病変を認めたため,2ヵ月後に残存した左固有腎尿管に対して鏡視下で腎尿管全摘術を施行したが,悪性所見は認めなかった.Surgical CRとして無治療経過観察としたが,術後半年で多発肺転移が出現した.ゲムシタビン・カルボプラチン療法を導入し,4コース終了までは肺転移がやや縮小したが,5コース終了後は増悪を認めていた.追加治療を希望せず緩和治療へ移行となり膀胱全摘後1年9ヵ月で癌死した.腎移植後であっても膀胱全摘および尿路変向手術は可能で,免疫抑制剤の調整により化学療法も完遂できた.腎移植後の進行性膀胱癌にエビデンスのある治療方針はなく,腎機能障害を有し免疫抑制状態であることを認識し,個々の症例で適切な薬物治療や外科的治療の選択をする必要がある.(著者抄録), (一社)日本泌尿器科学会, 日本語

    症例は17歳男性.生後2ヵ月時に左多精巣症と診断されたが,陰嚢内であり無症状であったため経過観察となっていた.17歳時に左急性陰嚢症を発症し,超音波検査にて左精巣捻転と診断され発症4時間後に,緊急手術が施行された.術中所見では,左頭側精巣が反時計回りに720度捻転していた.捻転解除により色調の改善を認めたため,頭側精巣生検を行い,両側精巣固定を行った.病理所見では,悪性所見を認めず,精子形成能は保たれていた.術後1年半経過するが,血流は良好で,精巣の萎縮はなく経過している.多精巣症は稀な疾患であり,幼少期に無症状で発見された陰嚢内に存在する多精巣症に対する治療方針は明らかではない.過去の報告では,停留精巣の有無により悪性腫瘍の発生頻度が異なることが報告されていることから,停留精巣の有無により治療方針を検討する必要がある.保存的な経過観察を推奨する意見もあるが,初期治療として経過観察を行ったとしても腫瘍発生や捻転のリスクを考慮したうえでの待機的な外科的処置も選択肢となりうる.(著者抄録), (一社)日本泌尿器科学会, 日本語

    正確な病期診断の観点、微小リンパ節転移摘除による潜在的治療効果の観点から、根治的膀胱全摘除術時には骨盤内リンパ節郭清が積極的に施行される。当科では、総腸骨動脈分岐部以下の骨盤内リンパ節郭清を行っている。いわゆる拡大郭清の範囲で、具体的には総腸骨領域、仙骨前面領域、外腸骨領域、内腸骨領域、閉鎖領域のリンパ節に該当する。正確な病期診断、微小リンパ節転移摘除による潜在的治療効果の面から、リンパ節郭清においては丁寧な手術操作を心がけることが肝要である。(著者抄録), 医学図書出版(株), 日本語

    対象は2012年12月〜2017年3月の32例(男性24例、女性8例、年齢中央値61歳)であった。アキシチニブ導入後の全生存率(OS)中央値は29ヵ月、無増悪生存率(PFS)中央値は11ヵ月であった。2nd-lineでアキシチニブを使用した19例におけるOS中央値は22ヵ月、PFS中央値は10ヵ月であり、3rd-line以降でアキシチニブを使用した13例におけるOS中央値は29ヵ月、PFS中央値は15.5ヵ月であった。多変量解析では骨転移ありの症例でOSが有意に短かった。アキシチニブ内服中に認めたG3以上の有害事象は高血圧9例(28%)、下痢7例(22%)、蛋白尿7例(22%)であるが、死亡症例はなく、アキシチニブは比較的安全に投与できた。後ろ向きの検討ではあるが、3rd-line以降のアキシチニブ投与でも有効性があることが示唆された。, 泌尿器科紀要刊行会, 日本語

    松本 隆児, 石崎 淳司, 内野 秀紀, 佐々木 芳浩, 坂下 茂夫, 帯広厚生病院医誌, 13, 9, 13, 2010年10月
    当科では1998年より腹腔鏡下副腎摘除術を開始しているので、その治療成績をまとめた。1998年9月より2009年6月まで当科で施行された腹腔鏡下副腎摘除102例を対象とした。疾患の内訳は原発性アルドステロン症23例、クッシング症候群18例、非機能性腺腫17例、褐色細胞腫23例、転移性腫瘍9例、のう胞5例、その他7例であった。平均手術時間は147.3(62〜455)分、平均出血量は96.9(2〜1465)ml、平均腫瘍径は2.94(1.0〜8.0)cm、平均BMI24.3(16〜44)であった。BMIが高いほど手術時間がやや長くなる傾向があったが、腫瘍径は手術時間に影響しなかった。また、BMIと出血量には相関がなかったが、腫瘍径が大きいほど出血量がやや多くなる傾向があった。開腹術移行を6例(5.9%)に認め、原因は癒着剥離困難3例、止血困難3例であった。合併症として胸膜損傷1例、術後胆嚢炎1例、術後肺塞栓1例、動脈損傷2例、輸血を要した術後出血1例認めた。開腹術移行・合併症の頻度は2004年6月までの51例中4例(7.8%)、それ以降の51例中4例(7.8%)と変わらなかった。比較的経験の少ない術者が執刀する機会が増えているためと考えられる。近年腹腔鏡下副腎摘除術は低侵襲な術式として確立しているが、当科でも安定した手術成績を残すことができた。(著者抄録), 帯広厚生病院, 日本語

    症例は66歳、男性。他院より紹介され、浸潤性膀胱癌に対して腹腔鏡下膀胱全摘除+尿道摘除+回腸導管造設術を施行した。術後4日目より38℃台の発熱あり、尿路感染あるいはカテーテル感染を考え抗生剤投与を開始したが、改善を認めなかった。各種細菌・真菌培養は陰性、画像上も明らかな感染巣を指摘でなかった。尿管カテーテル抜去時に予防的にCFPN(塩酸セフカペン)の内服を開始したところ発熱とともに急性腎不全となり、一時的に血液透析を導入した。透析導入と同時に腎生検を試行したところ、腎の間質への好酸球も含む、強い炎症細胞浸潤を認めたため、この時点で間質性腎炎として、ステロイド治療を開始した。ステロイド投与後は、解熱し炎症反応も陰性化、腎機能も改善し、透析も離脱した。原因薬剤の検索目的に薬剤負荷リンパ球幼若化試験を施行したところ、CFPNおよびMEPM(メロペネム)が陽性を示し、経過からはCFPNが原因薬剤と考えられた。術後に頻用される抗生剤や非ステロイド性抗炎症剤等の薬剤は腎障害をきたすことが知られており、使用の際には間質性腎炎の発症も念頭に置き、有症時には早期に対応することが必要である。(著者抄録), 市立札幌病院, 日本語

    膀胱憩室腫瘍の発生頻度は稀であり、憩室壁の組織学的特徴などから一般の膀胱腫瘍とは治療方針や予後が異なるとされている。当科における膀胱憩室腫瘍の治療成績を検討した。1986年1月から2007年6月までに診断された膀胱悪性腫瘍646例のうち、膀胱憩室腫瘍10例(1.5%)について検討した。男性8例、女性2例で診断時の年齢の中央値は76歳(66-84歳)と高齢であった。排尿障害を有する症例を6例認めた。膀胱憩室の発生部位は後壁4例、側壁4例、頂部1例、前壁1例であった。治療方法として経尿道的膀胱腫瘍切除術(TUR-Bt)単独が4例、膀胱部分切除術が4例(うち2例で尿管膀胱新吻合術を同時に施行した)。膀胱全摘除術が2例に施行された。組織型は7例が尿路上皮癌、2例が扁平上皮癌であった。異型度はG2以下が7例、G3が3例であり、深達度はT1以下が8例、T3が2例であった。carcinoma in situ(以下cis)の合併を3例に認めた。膀胱を温存した8例中4例で再発をきたしたものの、TUR-Btで治療が可能であった。予後は5年全生存率は63.6%、5年癌特異生存率は68.6%であった。膀胱憩室腫瘍は予後不良とされているが、腫瘍が憩室内に限局していれば早期の診断、治療および術後の注意深い経過観察により膀胱温存が可能であり、一般の膀胱腫瘍と遜色のない予後が得られると考える。(著者抄録), 帯広厚生病院, 日本語
  • 小径腎細胞癌に対する鏡視補助腎部分切除術の臨床的検討

    近年、腎細胞癌はCT、超音波などで画像診断が進歩、普及したことから、早期診断が可能となっている。腫瘍径40mm以下の小径腎細胞癌に対する治療では、根治性とともに患腎機能の温存、合併症の減少、低侵襲性などが目標とされてきた。今回当科で行っている腎部分切除術の治療成績を報告する。当院にて2000年6月から2007年6月の間に行われた腎癌手術は246例で、腫瘍径40mm以下の小径腎細胞癌に対するネフロン温存手術は59例(開放群31例、鏡視補助群28例)であった。2群間で手術時間、出血量、阻血時間、術中合併症、術後合併症、患腎機能の推移について比較検討した結果、手術時間(開放群平均121分、鏡視補助群平均150分)、阻血時間(開放群平均17分33秒、鏡視補助群平均7分56秒)以外有意差を認めなかった。2003年11月より、当院ではより低侵襲な鏡視補助腎部分切除術を導入しているが、根治性、患腎機能温存、合併症頻度に関して開腹手術に比べ遜色ないことがわかった。(著者抄録), 帯広厚生病院, 日本語

    AKR1C1阻害効果のあるフルフェナム酸やメフェナム酸といったフェナム酸系の非ステロイド性抗炎症薬には、膀胱癌細胞のシスプラチン感受性増大効果と細胞浸潤能抑制効果を認めた。臨床検体を用いた検討では、尿路上皮癌転移巣で原発巣に比べAKR1C1は有意に発現亢進しており、AKR1C1阻害剤による転移抑制効果、転移巣に対する抗癌剤治療効果増強が期待される結果であった。現在、マウスに両剤併用投与観察中であり、フェナム酸の適用量を検討している。
