    English, Scientific journal, Despite the pathological importance of oncofetal fibronectin isoforms associated with cancer cell progression and metastasis, our understanding of the structural and molecular details that occurred in this abundant and ubiquitous extracellular matrix component remains largely unknown. Here, we communicate that site-specific O-glycosylation in the oncofetal fibronectin creates cancer stage-specific serum biomarkers for hepatocellular carcinoma (HCC) by quantitative MS-based glycoproteomic approach. Selective reaction monitoring (SRM) using a structure-defined synthetic glycopeptide library enabled absolute quantitation of the targeted label-free tryptic fragments bearing cancer-relevant O-glycans derived from the type III homology connective segment (IIICS) domain of the oncofetal fibronectin (onfFN) in the sera of HCC patients and healthy controls. We found site-specific O-glycoform alteration from T/sialyl T antigens to Tn/sialyl Tn antigens at the consecutive threonine residues 2155Thr-Thr-Ala2157 within this fragment during cancer progression. Surprisingly, this dynamic glycoform alteration is observed specifically in the patient sera diagnosed newly as stage 2-4 groups not in the normal control and stage 1 patient groups. Our results provide compelling evidence that site-specific glycoform changes observed in the onfFN IIICS domain during the tumor proliferation elaborate new class cancer stage-relevant "dynamic epitopes" as highly potential cancer diagnostic and therapeutic targets.

    Hepatology research : the official journal of the Japan Society of Hepatology, 26 Jul. 2024, [International Magazine]
    English, Scientific journal, AIM: This study was undertaken to evaluate the outcome of curative liver resection, (LR) of Barcelona Clinic Liver Cancer stage C hepatocellular carcinoma (BCLC-C HCC) after tyrosine kinase inhibitors (TKIs) became approved as a treatment option for recurrent lesions. METHODS: Sixty-seven patients with BCLC-C HCC who underwent curative LR were enrolled in this study. The patients were classified into two groups according to whether LR was performed before (n = 24) or after (n = 43) TKI approval ("beforeTKI" and "afterTKI" group, respectively). RESULTS: There was no difference in the median disease-free survival time after LR between the beforeTKI and afterTKI groups (5.6 and 7.1 months, respectively; p = 0.435). However, the median survival time after LR was longer in the afterTKI than beforeTKI group (42.7 and 14.9 months, respectively; p = 0.022). Univariate and multivariate analyses showed that the date of LR was the only independent factor affecting postresection survival. When the patients were limited to those with recurrence, there were no differences in the recurrence pattern or progression of HCC at the time of recurrence between the two groups. The only difference in the treatment distribution was the administration of TKIs (14 of 34 patients in afterTKI group and only 1 of 19 patients in beforeTKI group, p < 0.001). CONCLUSION: These data suggest that TKI therapy for recurrent BCLC-C HCC is associated with improved overall survival. Thus, LR could be a promising option for BCLC-C HCC in the current era of TKI therapy.

    English, Scientific journal, BACKGROUND: Intrahepatic cholangiocarcinoma (ICC) has a high recurrence rate and a poor prognosis. Thus, the development of effective treatment and prognostic biomarkers is required. High expression of diacylglycerol kinase alpha (DGKα) is a prognostic factor for the recurrence of hepatocellular carcinoma. However, the relationship between DGKα expression and prognosis in ICC has not been reported. METHODS: Immunohistochemistry (IHC) with anti-DGKα antibody was performed on surgical specimens of ICC (n = 69). First, DGKα expression in cancer cells was qualitatively classified into four groups (-, 1+, 2+, 3+) and divided into two groups (DGKα- and DGKα+1 + to 3+). The relationship between clinical features and DGKα expression was analyzed. Second, Ki-67 expression was evaluated as a cell proliferation marker. The number of Ki-67-positive cells was counted, and the relationship with DGKα expression was examined. RESULTS: DGKα IHC divided the patients into a DGKα+ group (1+: n = 15; 2+: n = 5; 3+: n = 5) and a DGKα- group (-: n = 44). In the DGKα+ group, patients were older and had advanced disease. Both overall survival and recurrence-free survival (RFS) were significantly worse in the DGKα+ patients. DGKα+ was identified as an independent prognostic factor for RFS by multivariate analysis. Furthermore, the number of Ki-67-positive cells increased in association with the staining levels of DGKα. CONCLUSION: Pathological DGKα expression in ICC was a cancer proliferation marker associated with recurrence. This suggests that DGKα may be a potential therapeutic target for ICC.

    Clinical journal of gastroenterology, 17, 2, 356, 362, Apr. 2024, [Domestic magazines]
    English, Scientific journal, We here present a rare case of development of a postoperative pancreatic fistula and breakdown of the pancreaticojejunal anastomosis 8 months after pancreaticoduodenectomy. A 70-year-old man underwent pancreaticoduodenectomy for distal cholangiocarcinoma and initially recovered well. However, 8 months later, he developed abdominal pain and distention and was admitted to our institution with suspected pancreatitis. On the 17th day of hospitalization, he suddenly bled from the jejunal loop and a fluid collection was detected near the pancreaticojejunal anastomosis site. The fluid collection was drained percutaneously. Subsequent fistulography confirmed breakdown of the pancreaticojejunal anastomosis. Considering the patient's overall condition and the presence of postoperative adhesions, we decided to manage him conservatively. An additional drain tube was placed percutaneously from the site of the anastomotic breakdown into the lumen of the jejunum, along with the tube draining the fluid collection, creating a completely new fistula. This facilitated the flow of pancreatic fluid into the jejunum and was removed 192 days after placement. During a 6-month follow-up, there were no recurrences of pancreatitis or a pancreatic fistula. This case highlights the efficacy of percutaneous drainage and creation of an internal fistula as a management strategy for delayed pancreatic fistula and anastomotic breakdown following pancreaticoduodenectomy.
  • Expression of Wnt5a and ROR2, Components of the Noncanonical Wnt-Signaling Pathway, is Associated with Tumor Differentiation in Hepatocellular Carcinoma.

    Annals of surgical oncology, 31, 1, 262, 271, Jan. 2024, [International Magazine]
    English, Scientific journal, BACKGROUND: Wnt5a is the key ligand of the noncanonical Wnt pathway, and receptor tyrosine kinase-like orphan receptor 2 (ROR2) is a receptor associated with Wnt5a. The association between the noncanonical Wnt-signaling pathway and carcinogenesis in hepatocellular carcinoma (HCC) is unclear. This study investigated the significance of ROR2 expression in HCC. METHODS: The study examined ROR2 expression in liver cancer cell lines. Immunohistochemical staining of ROR2 was performed on 243 resected HCC specimens. The study investigated ROR2 expression and its association with clinicopathologic factors and prognosis. RESULTS: Findings showed that ROR2 was expressed in well-differentiated Huh7 and HepG2 cells, but not in poorly differentiated HLE and HLF cells. Expression of ROR2 was positive in 147 (60.5%) and negative in 96 (39.5%) HCC specimens. A significant association was shown between ROR2 negativity and high alpha-fetoprotein (AFP) level (P = 0.006), poor differentiation (P = 0.015), and Wnt5a negativity (P = 0.024). The 5-year overall survival (OS) rate for the ROR2-negative group (64.2 %) tended to be worse than for the ROR2-positive group (73.8%), but the difference was not significant (P = 0.312). The 5-year OS rate was 78.7% for the ROR2+Wnt5a+ group, 71.3 % for the ROR2+Wnt5a- group, 80.8% for the ROR2-Wnt5a+ group, and 60.5 % for the ROR2-Wnt5a- group. The OS in the ROR2-Wnt5a- group was significantly poorer than in the ROR2+Wnt5a+ group (P = 0.030). The multivariate analysis showed that Wnt5a-ROR2- was an independent prognostic factor (hazard ratio, 2.058; 95% confidence interval, 1.013-4.180; P = 0.045). CONCLUSIONS: The combination of ROR2 and Wnt5a may be a prognostic indicator for HCC. The Wnt5a/ROR2 signal pathway may be involved in the differentiation of HCC. This pathway may be a new therapeutic target for HCC.
  • Real-time tumor-tracking radiotherapy with SyncTraX for primary liver tumors requiring isocenter shift†.

    Journal of radiation research, 22 Nov. 2023, [International Magazine]
    English, Scientific journal, The SyncTraX series enables real-time tumor-tracking radiotherapy through the real-time recognition of a fiducial marker using fluoroscopic images. In this system, the isocenter should be located within approximately 5-7.5 cm from the marker, depending on the version, owing to the limited field of view. If the marker is placed away from the tumor, the isocenter should be shifted toward the marker. This study aimed to investigate stereotactic body radiotherapy (SBRT) outcomes of primary liver tumors treated with SyncTraX in cases where the isocenter was shifted marginally or outside the planning target volume (PTV). Twelve patients with 13 liver tumors were included in the analysis. Their isocenter was shifted toward the marker and was placed marginally or outside the PTV. The prescribed doses were generally 40 Gy in four fractions or 48 Gy in eight fractions. The overall survival (OS) and local control (LC) rates were calculated using the Kaplan-Meier method. All patients completed the scheduled SBRT. The median distance between the fiducial marker and PTV centroid was 56.0 (interquartile range [IQR]: 52.7-66.7) mm. By shifting the isocenter toward the marker, the median distance between the marker and isocenter decreased to 34.0 (IQR: 33.4-39.7) mm. With a median follow-up period of 25.3 (range: 6.9-70.0) months, the 2-year OS and LC rates were 100.0% (95% confidence interval: 100-100). An isocenter shift makes SBRT with SyncTraX feasible in cases where the fiducial marker is distant from the tumor.

    Microsurgery, 43, 6, 606, 610, Sep. 2023, [International Magazine]
    English, Chylous ascites, the leakage of lymphatic fluid into the abdominal cavity caused by lymphatic fluid stasis or lymphatic vessel damage, can be treated by lymphaticovenous anastomosis (LVA). We report rarely performed abdominal LVA to treat a case of refractory ascites possibly caused by ligation of the thoracic duct and pleurodesis in a man aged 60 years requiring weekly ascites drainage. Ligation was abandoned because the leakage site was not determined. The greater omentum (GO) was generally edematous and showed lymphatic effusion by gross appearance, and was considered suitable for LVA. We performed once LVA in the lymphatic vessels and veins of the GO using common microsurgical instrumentation and lateral anastomosis. Lymphatic vessels in the omentum were dilated to 2-3 mm, and LVA was simple. After LVA, GO edema improved. Postoperatively, the patient developed paralytic ileus, which improved within a few days, and the patient was discharged without any increase in ascites after starting to diet. One year post-surgery, there was no recurrence of ascites. LVA at the GO may be effective for the treatment of refractory chylous ascites because of its absorptive lymphatic draining capabilities and large transverse vessels.

    English, Scientific journal, OBJECTIVES: In a previous study of hepatic toxicity, the following three factors were identified to predict the benefits of proton beam therapy (PBT) for hepatocellular carcinomas (HCC) with a maximum diameter of ≤5 cm and Child-pugh grade A (CP-A): number of tumors (one vs ≥2), the location of tumors (hepatic hilum or others), and the sum of the diameters of lesions. The aim of this study is to analyze the association between these three factors and hepatic toxicity. METHODS: We retrospectively reviewed patients of CP-A treated with PBT or photon stereotactic body radiotherapy (X-ray radiotherapy, XRT) for HCC ≤5 cm. For normal liver dose, the V5, V10, V20 (volumes receiving 5, 10, and 20 Gy at least), and the mean dose was evaluated. The albumin-bilirubin (ALBI) and CP score changes from the baseline were evaluated at 3 and 6 months after treatment. RESULTS: In 89 patients (XRT: 48, PBT: 41), those with two or three (2-3) predictive factors were higher normal liver doses than with zero or one (0-1) factor. In the PBT group, the ALBI score worsened more in patients with 2-3 factors than those with 0-1 factor, at 3 months (median 0.26 vs 0.02, p = 0.032) and at 6 months (median: 0.35 vs 0.10, p = 0.009). The ALBI score change in the XRT group and CP score change in either modality were not significantly different in the number of predictive factors. CONCLUSIONS: The predictive factor numbers predicted the ALBI score change in PBT but not in XRT. ADVANCES IN KNOWLEDGE: This study suggest that the number of predictive factors previously identified (0-1 vs 2-3) were significantly associated with dosimetric parameters of the normal liver in both modalities. In the proton group, the number of predictive factors was associated with a worsening ALBI score at 3 and 6 months, but these associations were not found in the photon SBRT group.

    English, Scientific journal, BACKGROUND: A single hepatocellular carcinoma (HCC) is a good indication for hepatic resection regardless of tumor size, but the surgical indications for cases with multiple HCCs remain unclear. METHODS: We retrospectively reviewed the outcomes of hepatectomies for Barcelona Clinic Liver Cancer (BCLC) stage 0, A, and B HCCs. We further subclassified stage A and B into A1 (single nodule <5 cm, or three or fewer nodules ≤3 cm), A2 (single nodule 5-10 cm), A3 (single nodule ≥10 cm), B1 (two to three nodules >3 cm), and B2 (four or more nodules). RESULTS: A total of 1088 patients were enrolled, comprising 88 stage 0, 750 stage A (A1: 485; A2: 190; A3: 75), and 250 stage B (B1: 166; B2: 84) cases. The 5-year overall survival (OS) rates for stage 0, A1, A2, A3, B1, and B2 patients were 70.4%, 74.2%, 63.8%, 47.7%, 47.5%, and 31.9%, respectively (p < 0.0001). Significant differences in OS were found between stages A1 and A2 (p = 0.0118), A2 and A3 (p = 0.0013), and B1 and B2 (p = 0.0050), but not between stages A3 and B1 (p = 0.4742). In stage B1 patients, multivariate analysis indicated that Child-Pugh B cirrhosis was the only independent prognostic factor for the OS outcome. CONCLUSIONS: A hepatectomy should be considered for multiple HCCs if the number of tumors is three or fewer, especially in patients with no cirrhosis or in Child-Pugh A cases, because the long-term results are equivalent to those for a single HCC.

    English, Scientific journal, BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide. However, the number of patients with chronic kidney disease (CKD) is on the rise because of the increase in lifestyle-related diseases. AIM: To establish a tailored management strategy for HCC patients, we evaluated the impact of comorbid renal dysfunction (RD), as stratified by using the estimated glomerular filtration rate (EGFR), and assessed the oncologic validity of hepatectomy for HCC patients with RD. METHODS: We enrolled 800 HCC patients who underwent hepatectomy between 1997 and 2015 at our university hospital. We categorized patients into two (RD, EGFR < 60 mL/min/1.73 m2; non-RD, EGFR ≥ 60 mL/min/1.73 m2) and three groups (severe CKD, EGFR < 30 mL/min/1.73 m2; mild CKD, 30 ≤ EGFR < 60 mL/min/1.73 m2; control, EGFR ≥ 60 mL/min/1.73 m2) according to renal function as defined by the EGFR. Overall survival (OS) and recurrence-free survival (RFS) were compared among these groups with the log-rank test, and we also analyzed survival by using a propensity score matching (PSM) model to exclude the influence of patient characteristics. The mean postoperative observation period was 64.7 ± 53.0 mo. RESULTS: The RD patients were significantly older and had lower serum total bilirubin, aspartate aminotransferase, and aspartate aminotransferase levels than the non-RD patients (P < 0.0001, P < 0.001, P < 0.05, and P < 0.01, respectively). No patient received maintenance hemodialysis after surgery. Although the overall postoperative complication rates were similar between the RD and non-RD patients, the proportions of postoperative bleeding and surgical site infection were significantly higher in the RD patients (5.5% vs 1.8%; P < 0.05, 3.9% vs 1.8%; P < 0.05, respectively), and postoperative bleeding was the highest in the severe CKD group (P < 0.05). Regardless of the degree of comorbid RD, OS and RFS were comparable, even after PSM between the RD and non-RD groups to exclude the influence of patient characteristics, liver function, and other causes of death. CONCLUSION: Comorbid mild RD had a negligible impact on the prognosis of HCC patients who underwent curative hepatectomy with appropriate perioperative management, and close attention to severe CKD is necessary to prevent postoperative bleeding and surgical site infection.

    Surgical case reports, 8, 1, 63, 63, 08 Apr. 2022, [International Magazine]
    English, Scientific journal, BACKGROUND: Alveolar echinococcosis (AE) is a rare parasitic disease caused by the larva of Echinococcus multilocularis. It nearly always occurs in the liver, and cardiac involvement is extremely rare. Liver resection is the most effective intervention for AE because the only potentially curative treatment is removal of the lesion. Even when complete resection is not performed, long-term survival can be expected after surgical removal of most of the lesion with lifelong administration of albendazole (ABZ). CASE PRESENTATION: A 64-year-old man who lived in Hokkaido was referred to our hospital due to abnormalities in biliary enzymes. According to the findings from enhanced computed tomography and magnetic resource imaging of the abdomen, transthoracic echocardiography and serologic tests, he was diagnosed with hepatic AE with rupture into the pericardium. He underwent extended left hemi-hepatectomy with reconstruction of the inferior vena cava and opening of the pericardium with drainage as reduction surgery. Pathological examination revealed echinococcal infection in the pericardium as well as the liver. He started chemotherapy with 400 mg ABZ per Day 67 days after surgery. Although the surgical margin was positive in the pathological findings, he was alive 19 months later with no regrowth of the echinococcal lesion. CONCLUSION: AE with cardiac involvement is extremely rare. Even if the complete removal of cardiac-involved AE is not possible, surgical debulking with lifelong ABZ treatment can successfully manage the disease.

    Surgical case reports, 8, 1, 47, 47, 21 Mar. 2022, [International Magazine]
    English, Scientific journal, BACKGROUND: Although there is no established treatment strategy for liver metastasis of leiomyosarcoma, liver resection has been reported to be effective in some cases. However, almost all liver resections performed for liver metastasis of primary leiomyosarcoma are reported to be open resections, and there are few reports of liver resection performed by laparoscopy. Here, we report a case of laparoscopic liver resection for liver metastasis of a leiomyosarcoma in the right thigh. CASE PRESENTATION: An 80-year-old man was diagnosed with leiomyosarcoma of the right thigh with liver metastasis. The primary tumor was first resected, and he was discharged on the 25th postoperative day. Four months after primary tumor resection, a laparoscopic right posterior sectionectomy was performed. There were no postoperative complications, and the patient was discharged on the 11th postoperative day with a histopathological diagnosis of liver metastasis of leiomyosarcoma and negative resection margins. Currently, 9 months have passed since the resection of the primary tumor, and 5 months have passed since the laparoscopic liver resection; there is no recurrence. CONCLUSIONS: The liver metastasis of leiomyosarcoma was successfully removed, with good short-term outcomes after the laparoscopic liver resection. Laparoscopic liver resection seems to be effective for liver metastasis of leiomyosarcoma, which is characterized by a high recurrence rate after surgery. However, more case studies may be necessary to examine the effectiveness and long-term results of laparoscopic liver resection for the treatment of liver metastasis of leiomyosarcoma.

    English, Scientific journal, PURPOSE: Active hexose-correlated compound (AHCC), a standardized extract of cultured Lentinula edodes mycelia, exerts antitumor effects through anti-inflammatory and immune-modulatory functions. Adjuvant therapy for patients with hepatocellular carcinoma (HCC) who have undergone curative hepatectomy has not been established. The purpose of this study was to evaluate the efficacy and safety of AHCC as adjuvant therapy in patients with advanced HCC after curative hepatectomy. PATIENTS AND METHODS: The study design was single-armed, non-randomized, open (no one was blinded), and uncontrolled. Patients with HCC who underwent curative hepatectomy were treated with AHCC (1 g) 3 times daily orally for 2 years. The inclusion criteria were HCC diagnosed preoperatively as stages A and B of the Barcelona clinic liver cancer (BCLC) classification and alpha-fetoprotein × protein induced by vitamin K absence or antagonist II (PIVKA-II) ≥ 105 for stage A. RESULTS: A total of 29 patients were treated with AHCC, of which 25 (4 patients discontinued) were followed up. The 2-year recurrence-free survival rate after resection was 48% for those without discontinuations and 55.2% for all patients with a history of treatment. Serum albumin levels decreased to a minimum in the first postoperative month and gradually recovered to the preoperative level at 6 months. Almost no change in lymphocyte percentage was observed during follow-up. Inflammation-based prognostic scores were maintained at favorable levels after hepatectomy. Toxicity and adverse events were not observed in any patient. CONCLUSION: AHCC may be safe and effective in preventing HCC recurrence after curative hepatectomy, and further randomized trials of AHCC for its use in this setting are warranted.This clinical trial was registered in UMIN Clinical Trials Registry (ID UMIN000024396).

    English, Scientific journal, BACKGROUND: The prognosis of advanced hepatocellular carcinoma (HCC) that is not indicated for curative hepatectomy remains poor, despite advances in the treatment of HCC, including the development of tyrosine kinase inhibitors (TKIs). The outcomes of reduction hepatectomy and multidisciplinary postoperative treatment for advanced HCC that is not indicated for curative hepatectomy, including those of recently treated cases, should be investigated. AIM: To examine the outcomes of combination treatment with reduction hepatectomy and multidisciplinary postoperative treatment for advanced HCC that is not indicated for curative hepatectomy. METHODS: Thirty cases of advanced HCC that were not indicated for curative hepatectomy, in which reduction hepatectomy was performed between 2000 and 2018 at the Department of Gastroenterological Surgery I, Hokkaido University Graduate School of Medicine, were divided into postoperative complete remission (POCR) (+) and POCR (-) groups, depending on whether POCR of all evaluable lesions was achieved through postoperative treatment. The cases in the POCR (-) group were subdivided into POCR (-) TKI (+) and POCR (-) TKI (-) groups, depending on whether TKIs were administered postoperatively. RESULTS: The 5-year overall survival rate and mean survival time (MST) after reduction hepatectomy were 15.7% and 28.40 mo, respectively, for all cases; 37.5% and 56.55 mo, respectively, in the POCR (+) group; and 6.3% and 14.84 mo, respectively, in the POCR (-) group (P = 0.0041). Tumor size, major vascular invasion, and the number of tumors in the remnant liver after the reduction hepatectomy were also found to be related to survival outcomes. The number of tumors in the remnant liver was the only factor that differed significantly between the POCR (+) and POCR (-) groups, and POCR was achieved significantly more frequently when ≤ 3 tumors remained in the remnant liver (P = 0.0025). The MST was 33.52 mo in the POCR (-) TKI (+) group, which was superior to the MST of 10.74 mo seen in the POCR (-) TKI (-) group (P = 0.0473). CONCLUSION: Reduction hepatectomy combined with multidisciplinary postoperative treatment for unresectable advanced HCC that was not indicated for curative hepatectomy was effective when POCR was achieved via multidisciplinary postoperative therapy. To achieve POCR, reduction hepatectomy should aim to ensure that ≤ 3 tumors remain in the remnant liver. Even in cases in which POCR is not achieved, combined treatment with reduction hepatectomy and multidisciplinary therapy can improve survival outcomes when TKIs are administered.

    English, Scientific journal, BACKGROUND: Pancreaticoduodenal artery aneurysms (PDAAs) are rare visceral aneurysms, and prompt intervention/treatment of all PDAAs is recommended at the time of diagnosis to avoid rupture of aneurysms. Herein, we report two cases of PDAA caused by the median arcuate ligament syndrome, treated with surgical revascularization by aortosplenic bypass followed by coil embolization. CASE PRESENTATION: Case 1 A 54-year-old woman presented with a chief complaint of severe epigastralgia and was diagnosed with two large fusiform inferior PDAAs and celiac axis occlusion. To preserve the blood flow of the pancreatic head, duodenum, liver, and spleen, we performed elective surgery to release the MAL along with aortosplenic bypass. At 6 days postoperatively, transcatheter arterial embolization was performed. At the 8-year 6-month follow-up observation, no recurrent perfusion of the embolized PDAAs or rupture had occurred, including the non-embolized small PDAA, and the bypass graft had excellent patency. Case 2 A 39-year-old man who had been in good health was found to have a PDAA with celiac stenosis during a medical checkup. Computed tomography and superior mesenteric arteriography showed severe celiac axis stenosis and a markedly dilated pancreatic arcade with a large saccular PDAA. To preserve the blood flow of the pancreatic arcade, we performed elective surgery to release the MAL along with aortosplenic bypass. At 9 days postoperatively, transcatheter arterial embolization was performed. At the 6-year 7-month follow-up observation, no recurrent perfusion or rupture of the PDAA had occurred, and the bypass graft had excellent patency. CONCLUSION: Combined treatment with bypass surgery and coil embolization can be an effective option for the treatment of PDAAs associated with celiac axis occlusion or severe stenosis.

    English, Scientific journal, Neuroendocrine tumors (NETs) account for approximately 1-2% of all gastrointestinal tumors. In particular, primary hepatic NETs (PHNETs) are extremely rare. A 42-year-old female patient was given a diagnosis of liver tumor after a medical check-up with ultrasonography. An enhanced CT scan and MRI were suggestive for a hepatic hemangioma or adenoma, but the possibility of hepatocellular carcinoma could not be denied. Moreover, this tumor grew larger, so we performed a laparoscopic partial hepatectomy for the diagnosis and treatment of the patient. Pathological examination revealed that the tumor cells were spindle-shaped, forming glandular-tubular structures, and had less visible nucleoli and increased mitotic figures on H&E staining. Immunohistochemical findings indicated that CK19, MOC-31, CD56, synaptophysin, and chromogranin A were positive; CK7, AFP, and glypican-3 were negative; and the Ki-67 index was 3.6%, so the final diagnosis was a PHNET G2. PHNETs differ from other NETs, as they do not produce biologically active polypeptides or amines. As a result, there are no manifestations of carcinoid syndrome. In addition, PHNETs grow slowly, and most patients show no symptoms in the early stages. Laparoscopic hepatectomy is a very useful procedure for diagnosis and treatment in such cases and can be performed safely.

    Quantitative imaging in medicine and surgery, 11, 6, 2572, 2585, Jun. 2021, [International Magazine]
    English, Scientific journal, Background: Liver elastography with virtual touch quantification (VTQ) measures the velocity of the shear wave generated by a short-duration acoustic force impulse, with values expressed in units of velocity (m/s). VTQ can evaluate right or left hepatic lobes separately. VTQ might be appropriate for the evaluation of future remnant liver after hepatectomy. Methods: We analyzed 95 patients underwent liver elastography with VTQ and both future remnant liver and resected side before hepatectomy of more than two sections, except for central bisectionectomy. We divided the patients into a high VTQ group (≥1.52 m/s, n=37, 39%) and a low VTQ group (<1.52 m/s, n=58, 61%) according to the VTQ of future remnant liver. Transient elastography could not be performed in 22 cases due to tumor size. We defined the group with liver stiffness measurement (LSM) ≥7.9 kPa as the high LSM group (n=29, 40%) and those with LSM <7.9 kPa as the low LSM group (n=44, 60%). We investigated the outcome after hepatectomy and the correlations between the VTQ of future remnant liver and other indicators for hepatic fibrosis. Results: The high VTQ group showed significantly higher postoperative ascites (19% vs. 3%; P=0.01), pathological fibrosis (19% vs. 5%; P=0.03), and rates of patients with postoperative T-bil ≥2.0 mg/dL (70% vs. 40%; P<0.01). The high LSM group showed no significant postoperative outcomes compared to the low LSM group. The high VTQ group showed a higher frequency of male gender (78% vs. 57%; P=0.03), higher indocyanine green retention rate at 15 min (ICGR15) (10.5% vs. 6.3%; P<0.01), hyaluronic acid (100 vs. 67 ng/mL; P=0.02), type IV collagen 7S (7.6 vs. 5.1 ng/mL; P<0.01), Mac-2 binding protein glycan isomer (M2BPGi) (1.19 vs. 1.00; P=0.01), Fibrosis-4 (FIB-4) index (2.25 vs. 1.76; P=0.01), and aspartate aminotransferase to platelet ratio index (APRI) score (0.64 vs. 0.41; P<0.01). We also observed an especially strong positive correlation between the high VTQ and hyaluronic acid or type IV collagen 7S. Conclusions: Elastography with VTQ for future remnant liver before major hepatectomy is an accurate and useful method as a preoperative evaluation.

    English, Scientific journal, AIM: To report the outcomes of stereotactic body radiotherapy (SBRT) using a real-time tumor-tracking radiotherapy (RTRT) system for hepatocellular carcinoma (HCC) patients. METHODS: From January 2005 to July 2018, 63 patients with 74 lesions with a maximum diameter ≤52 mm were treated by SBRT using the RTRT system. No patient with a Child-Pugh Score ≥9 was included and 85.6% had a score of 5 or 6. Using the biological effective dose (BED) with α/β ratio of 10 (BED10 ), the median dose in BED10 at the reference point was 76.8 Gy (range: 60-122.5). Overall survival (OS) and local control (LC) rates were assessed using the Kaplan-Meier method. RESULTS: With a median follow up period of 24.6 months (range: 0.9-118.4), the 1-year and 2-year OS rates were 86.8% (95% confidence interval [95% CI]; 75.8-93.3) and 71.1% (57.8-81.6), respectively. The 2-year OS was 89.6% in patients with the baseline modified albumin-bilirubin (mALBI) grade =1 and 61.7% in patients with grade ≥2a. In the multivariate analysis, the mALBI grade (=1 vs ≥2a) was a significant factor for OS (p=0.028, 95%CI: 1.11-6.18). The 1-year and 2-year LC rates were 100% (100-100) and 92.0% (77.5-97.5). The LC rates were significantly higher in the BED10 ≥100 Gy group than in the BED10 <100 Gy (2-year 100% vs 86.5%, p=0.049) at the reference point. CONCLUSION: This retrospective study of SBRT using RTRT for HCC showed favorable outcomes with lower incidence of toxicities, especially in patients treated with BED10 ≥100 Gy to the reference point.

    English, Scientific journal, Prevalence of inflammatory bowel disease has been on the rise in recent years, especially in pediatric populations. This study aimed to provide precise identification and stratification of pediatric patients with diagnosed ulcerative colitis (UC) according to the severity of their condition and the prediction for standard treatment according to the specific expression of candidate miRNAs. We enrolled consecutive, therapeutically naïve, pediatric UC patients with confirmed pancolitis. We examined formalin-fixed paraffin-embedded specimens of colonic tissue for the expression of 10 selected candidate miRNAs. We performed receiver operating characteristic curve analysis, using area under the curve and a logistic regression model to evaluate the diagnostic and predictive power of the miRNA panels. Sixty patients were included in the final analysis. As a control group, 18 children without macroscopic and microscopic signs of inflammatory bowel disease were examined. The combination of three candidate miRNAs (let-7i-5p, miR-223-3p and miR-4284) enabled accurate detection of pediatric UC patients and controls. A panel of four candidate miRNAs (miR-375-3p, miR-146a-5p, miR-223-3p and miR-200b-3p) was associated with severity of UC in pediatric patients and a combination of three miRNAs (miR-21-5p, miR-192-5p and miR-194-5p) was associated with early relapse of the disease. Nine patients out of the total were diagnosed with primary sclerosing cholangitis (PSC) simultaneously with ulcerative colitis. A panel of 6 candidate miRNAs (miR-142-3p, miR-146a-5p, miR-223-3p, let-7i-5p, miR-192-5p and miR-194-5p) identified those patients with PSC. Specific combinations of miRNAs are promising tools for potential use in precise disease identification and severity and prognostic stratification in pediatric patients with ulcerative pancolitis.

    English, Scientific journal, BACKGROUND: In terms of anatomical liver sectionectomy approaches, both a central hepatectomy (CH) and major hepatectomy (MH) are feasible options for a centrally located hepatocellular carcinoma (HCC). METHODS: We retrospectively reviewed the surgical outcomes of central HCC patients who underwent CH or MH. MH includes hemihepatectomy or trisectionectomy, whereas CH involves a left medial sectionectomy, right anterior sectionectomy, or central bisectionectomy. The surgical outcomes were compared before and after propensity score matching (PSM). RESULTS: A total of 233 patients were enrolled, including 132 in the CH group and 101 in the MH group. The MH group cases were pathologically more advanced and had poorer overall survival rates than the CH group. After PSM, 68 patients were selected into each group, both of which showed similar overall and recurrence-free survival outcomes. The CH group showed a tendency for a longer operation time; however, other perioperative outcomes were similar between the two groups. Multivariate analyses of our matched HCC patients revealed that the type of surgery (CH or MH) was not an independent prognostic factor. More patients in the matched CH group experienced a repeat hepatectomy for recurrence and no patients in this group underwent a preoperative portal vein embolization. CONCLUSIONS: The short- and long-term surgical outcomes of CH and MH for a centrally located HCC are similar under a matched clinicopathological background. CH has the advantage of not requiring a preoperative portal vein embolization and increased chances of conducting a repeat hepatectomy for recurrence.

    English, Scientific journal, BACKGROUND: Preoperative portal vein embolization (PVE) is a widely used strategy to enable major hepatectomy in patients with insufficient liver remnant. PVE induces hypertrophy of the future liver remnant (FLR) and a shift of the functional reserve to the FLR. However, whether the increase of the FLR volume (FLRV) corresponds to the functional transition after PVE remains unclear. AIM: To investigate the sequential relationship between the increase in FLRV and functional transition after preoperative PVE using 3-dimensional (3D) computed tomography (CT) and 99mTc-galactosyl-human serum albumin (99mTc-GSA) single-photon emission computed tomography (SPECT) fusion images. METHODS: Thirty-three patients who underwent major hepatectomy following PVE at the Department of Gastroenterological Surgery I, Hokkaido University Hospital between October 2013 and March 2018 were enrolled. Three-phase dynamic multidetector CT and 99mTc-GSA SPECT scintigraphy were performed at pre-PVE, and at 1 and 2 wk after PVE; 3D 99mTc-GSA SPECT CT-fused images were constructed from the Digital Imaging and Communications in Medicine data using 3D image analysis system. Functional FLRV (FFLRV) was defined as the total liver volume × (FLR volume counts/total liver volume counts) on the 3D 99mTc-GSA SPECT CT-fused images. The calculated FFLRV was compared with FLRV. RESULTS: FFLRV increased by a significantly larger extent than FLRV at 1 and 2 wk after PVE (P < 0.01). The increase in FFLRV and FLRV was 55.1% ± 41.6% and 26.7% ± 17.8% (P < 0.001), respectively, at 1 wk after PVE, and 64.2% ± 33.3% and 36.8% ± 18.9% (P < 0.001), respectively, at 2 wk after PVE. In 3 of the 33 patients, FFLRV levels decreased below FLRV at 2 wk. One of the three patients showed rapidly progressive fatty changes in FLR. The biopsy at 4 wk after PVE showed macro- and micro-vesicular steatosis of more than 40%, which improved to 10%. Radical resection was performed at 13 wk after PVE. The patient recovered uneventfully without any symptoms of pos-toperative liver failure. CONCLUSION: The functional transition lagged behind the increase in FLRV after PVE in some cases. Evaluating both volume and function is needed to determine the optimal timing of hepatectomy after PVE.

    Surgery today, 04 Jan. 2021, [Domestic magazines]
    English, Scientific journal, Hepatectomy had a high mortality rate in the previous decade because of inadequate techniques, intraoperative blood loss, liver function reserve misdiagnoses, and accompanying postoperative complications. However, the development of several modalities, including intraoperative ultrasonography (IOUS), has made hepatectomy safer. IOUS can provide real-time information regarding the tumor position and vascular anatomy of the portal and hepatic veins. Systematic subsegmentectomy, which leads to improved patient outcomes, can be performed by IOUS in open and laparoscopic hepatectomy. Although three-dimensional (3D) computed tomography and gadoxetic acid-enhanced magnetic resonance imaging have been widely used, IOUS and contrast-enhanced IOUS are important modalities for risk analyses and making decisions regarding resectability and operative procedures because of the vital anatomical information provided and high sensitivity for liver tumors, including "disappearing" liver metastases. Intraoperative color Doppler ultrasonography can be used to delineate the vascular anatomy and evaluate the blood flow volume and velocity in hepatectomy patients and recipients of deceased- and living-donor liver transplantation after vessel reconstruction and liver positioning. For liver surgeons, IOUS is an essential technique to perform highly curative hepatectomy safely, although recent advances have also been made in virtual modalities, such as real-time virtual sonography with 3D visualization.

    English, Scientific journal, Background and Aim: Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (EOB-MRI) has been recognized as a useful imaging technique to distinguish the biological behavior of hepatocellular carcinoma (HCC). Methods: We analyzed 217 hepatectomy recipients with HCCs measuring 10 cm or less. We divided the patients into a decreased intensity (DI) group (n = 189, 87%) and an increased or neutral intensity (INI) group (n = 28, 13%) according to the ratio of tumor intensity to liver intensity during the hepatobiliary phase (HBP). According to the ratio of the maximum tumor diameter (including peritumoral hypointensity) between HBP images and precontrast T1-weighted images (RHBPP), we divided the patients as follows: The group whose RHBPP was ≥1.036 was the high RHBPP group (n = 60, 28%), and the group whose RHBPP was <1.036 was the low RHBPP group (n = 157, 72%). We investigated the prognoses and clinicopathological characteristics of these patients. Results: DI versus INI was not a prognostic factor for either survival or recurrence; however, a high RHBPP was an independent predictor of unfavorable survival and recurrence in patients. In addition, the INI group showed significantly lower α-fetoprotein (AFP) levels and higher rates of well-differentiated HCC and ICGR15 ≥15% than the DI group. The high RHBPP group showed significantly higher rates of vascular invasion and poorly differentiated HCC than the low RHBPP group. Conclusions: A high RHBPP by EOB-MRI is a preoperative predictor of vascular invasion and an unfavorable prognostic factor for survival and recurrence. These patients might be considered for highly curative operations such as anatomical liver resection.

    English, Scientific journal, The N‑glycoforms of glycoproteins modify protein function and control a number of biological pathways. The aim of the present study was to investigate the correlation between alterations in N‑glycans and cancer aggressiveness in terms of cancer cell invasion ability. The expression of urokinase‑type plasminogen activator (uPA) and N‑acetylglucosaminyltransferase V (GnT‑V) in liver cancer cell lines was analyzed by western blotting. Cell invasiveness was analyzed by Matrigel invasion assays. uPA and GnT‑V expression in liver cancer cell lines was knocked down by RNA interference. Furthermore, uPA was overexpressed in liver cancer cells using lentiviral vectors, and a mutant strain of HepG2 cells overexpressing uPA deficient in N‑glycans was established. A glycoblotting‑assisted matrix‑assisted laser desorption/ionization‑time‑of‑flight/mass spectrometry‑based quantitative analysis of liver cancer cell lines was performed, in which invasiveness was altered by modifying the expression of uPA and GnT‑V. N‑glycan profiles were found to differ between the highly invasive liver cancer cell line HLE and the less invasive cell line HepG2. The expression of several N‑glycans, including a form with m/z=1892, was changed according to invasiveness controlled by knockdown and overexpression of uPA. The invasiveness of HepG2 cells with mutant uPA did not increase regardless of the level of expression of uPA. Following GnT‑V knockdown and N‑glycan alteration, uPA expression did not change, whereas cell invasiveness decreased. One N‑glycan (m/z=1892) was common among N‑glycans in the comparative analysis between HLE and HepG2, HLE and uPA knockdown HLE, HepG2 and uPA‑overexpressing HepG2, and HLE and GnT‑V knockdown HLE cells and among N‑glycan profiles in human uPA. Therefore, N‑glycosylation is an important factor controlling invasiveness of liver cancer cells, and a specific N‑glycan (m/z=1892) associated with the invasion of liver cancer cells via uPA was identified in the present study.

    Hepatology research : the official journal of the Japan Society of Hepatology, 50, 2, 258, 267, Feb. 2020, [Peer-reviewed], [International Magazine]
    English, Scientific journal, AIM: A new classification of combined hepatocellular cholangiocarcinoma (CHC) was recently reported. Cancer stem cells have been associated with CHC carcinogenesis. This study examined the association of cancer stem cell marker expression and prognosis in CHC classified using the new classification. METHODS: We enrolled 26 CHC patients and classified them according to the new classification. We evaluated the expression of cancer stem cell markers (CD56, CD133, and epithelial cell adhesion molecule [EpCAM]) by immunohistochemical staining in each component. We analyzed the association between expressions and prognosis. RESULTS: Seven cases were hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) (cHCC-CCA), 12 were HCC and intermediate cell carcinoma (HCC-INT), and seven were intermediate cell carcinoma (INT). The CD133-positive rate tended to be higher in the CCA (42.9%) and INT component (50.0%) than the HCC component (14.3%) in cHCC-CCA. In HCC-INT, the CD133-positive rate in the INT component (83.3%) was significantly higher than the HCC component (8.3%; P = 0.001). For EpCAM, the positive rate in the CCA component (71.4%) and INT component (50.0%) tended to be higher than the HCC component (14.3%) in cHCC-CCA. Overall survival and disease-free survival were significantly worse in cases with CD133-positive (P = 0.048 and P = 0.048, respectively) or EpCAM-positive (P = 0.041 and P = 0.041, respectively) CCA component in cHCC-CCA. CONCLUSIONS: INT and CCA components showed higher expression rates of cancer stem cell markers than the HCC component. CD133 or EpCAM expression in the CCA component was associated with poor prognosis in cHCC-CCA.

    English, Scientific journal, BACKGROUND: Numerous driver mutations have been identified in colorectal cancer (CRC), but their relevance to the development of targeted therapies remains elusive. The secondary effects of pathogenic driver mutations on downstream signaling pathways offer a potential approach for the identification of therapeutic targets. We aimed to identify differentially expressed genes as potential drug targets linked to driver mutations. METHODS: Somatic mutations and the gene expression data of 582 CRC patients were utilized, incorporating the mutational status of 39,916 and the expression levels of 20,500 genes. To uncover candidate targets, the expression levels of various genes in wild-type and mutant cases for the most frequent disruptive mutations were compared with a Mann-Whitney test. A survival analysis was performed in 2100 patients with transcriptomic gene expression data. Up-regulated genes associated with worse survival were filtered for potentially actionable targets. The most significant hits were validated in an independent set of 171 CRC patients. RESULTS: Altogether, 426 disruptive mutation-associated upregulated genes were identified. Among these, 95 were linked to worse recurrence-free survival (RFS). Based on the druggability filter, 37 potentially actionable targets were revealed. We selected seven genes and validated their expression in 171 patient specimens. The best independently validated combinations were DUSP4 (p = 2.6 × 10-12) in ACVR2A mutated (7.7%) patients; BMP4 (p = 1.6 × 10-04) in SOX9 mutated (8.1%) patients; TRIB2 (p = 1.35 × 10-14) in ACVR2A mutated patients; VSIG4 (p = 2.6 × 10-05) in ANK3 mutated (7.6%) patients, and DUSP4 (p = 7.1 × 10-04) in AMER1 mutated (8.2%) patients. CONCLUSIONS: The results uncovered potentially druggable genes in colorectal cancer. The identified mutations could enable future patient stratification for targeted therapy.

    English, Scientific journal, BACKGROUND: Percutaneous transhepatic portal embolization (PTPE) is useful for safe major hepatectomy. This study investigated the correlation between hepatic hypertrophy and hemodynamics of portal venous flow by ultrasound sonography after PTPE. METHODS: We analyzed 58 patients with PTPE, excluding those who underwent recanalization (n = 10). Using CT volumetry results 2 weeks after PTPE, the patients were stratified into a considerable hypertrophy group (CH; n = 15) with an increase rate of remnant liver volume (IR-RLV) ≥ 40% and a minimal hypertrophy group (MH; n = 33) with an IR-RLV < 40%. We investigated the hemodynamics of portal venous flow after PTPE and the favorable factors for hepatic hypertrophy. RESULTS: Univariate and multivariate analysis identified the indocyanine green retention rate at 15 min (ICGR15) and increase rate of portal venous flow volume (IR-pFV) at the non-embolized lobe on day 3 after PTPE as independent favorable factors of IR-RLV. Patients with IR-pFV on day 3 after PTPE ≥100% and ICGR15 ≤ 15% (n = 13) exhibited significantly increased IR-RLV compared with others (n = 35). CONCLUSIONS: Cases with high IR-pFV on day 3 after PTPE exhibited better hepatic hypertrophy. Preserved liver function and increased portal venous flow on day 3 were important.

    English, The prognosis of metastatic gastrointestinal stromal tumor (GIST) has improved since the introduction of imatinib mesylate; however, acquired resistance has been reported, so alternative treatment option is needed. We evaluated the efficacy of hepatectomy for metastatic GIST. Six patients with liver metastases from GIST underwent hepatectomy. Four were treated with imatinib mesylate before hepatectomy, and all the patients were treated with imatinib mesylate after hepatectomy. Patients were followed-up for a mean duration of 113.5 months after hepatectomy. Complete resection was accomplished in four patients, with incomplete resection performed in the remaining two patients due to peritoneal dissemination. One patient with incomplete resection died 10 months after surgery. One patient with complete resection has survived without disease progression since initial hepatectomy. The remaining four patients with progressive disease during imatinib mesylate treatment developed tumor recurrence and three of them underwent a second hepatectomy. These three patients underwent complete resection during repeat surgery. In total, three patients died during the follow-up period, all of whom had tumors of small intestine origin. Primary tumor site (small intestine vs. others) was identified as a risk factor of mortality (P = 0.02). Although not statistically significant, there was a trend toward better outcomes in patients with exon 11 mutations. Surgical resection for metastatic GIST was shown to be effective and needed to achieve a better prognosis. Repeat hepatectomy demonstrated efficacy in selected patients. Hepatectomy should be considered based on tumor characteristics such as primary tumor site and c-KIT mutation status.
  • Fatty acid-binding protein 5 function in hepatocellular carcinoma through induction of epithelial-mesenchymal transition.

    English, Scientific journal, Hepatocellular carcinoma (HCC) is a highly prevalent cancer with poor prognosis. The correlation between overexpression of fatty acid-binding protein 5 (FABP5) and malignant potential of tumor growth and metastasis in several cancers has been previously reported. However, the correlation between FABP5 expression and HCC malignant behavior remains unknown. We compared FABP5 expression and patient characteristics in paired HCC and adjacent noncancerous liver tissues from 243 patients who underwent surgical resection of primary HCC. Cell proliferation, invasion, and migration assays were performed in HCC cell lines overexpressing FABP5 or downregulated for FABP5. Tumor growths were monitored in xenograft model, and liver and lung metastasis models were established. In the 243 HCC patients, FABP5-positive staining (n = 139/243, 57.2%) was associated with poor prognosis and recurrence (P < 0.0001) and showed positive correlation with distant metastasis, tumor size and vascular invasion (P < 0.05). Cell proliferation, invasion, and migration in vitro were enhanced by upregulation of FABP5 and decreased by downregulation of FABP5 in HCC cell lines. Similar results in tumor formation and metastasis were obtained through in vivo analyses. PCR array results revealed upregulation of SNAI1 in FABP5-overexpressing HepG2 cells. Western blot analysis showed significantly increased expression of E-cadherin and ZO-1 and decreased SNAI1 expression and nuclear translocation of β-catenin by knockdown of FABP5. We revealed a significant role for FABP5 in HCC progression and metastasis through the induction of epithelial-to-mesenchymal transition. FABP5 may be a potential novel prognostic biomarker and new therapeutic target for HCC.

    Japanese, Scientific journal, We analyzed 26 cases of unresectable or recurrent gastric cancer treated with oxaliplatin(OX)combination therapy between September 2014 and January 2016. The number of unresectable gastric cancer cases was 14 and there were 12 recurrent cases. The number of patients receiving S-1 plus OX(SOX), SOX plus trastuzumab(Tmab), capecitabine(Cape)plus OX(CapeOX), and CapeOX plus Tmab was 17, 1, 6, and 2, respectively. The starting dose of OX was 130mg/m2 in 12 patients and 100mg/m2 in 14. The median follow-up duration from the first treatment was 6 months(1-14). The median number of treatment cycles was 5(1-19). Dose reductions occurred in 14 cases, and treatment delay occurred in 13 cases. Grade 3 adverse events occurred in 2 cases(8%); thrombocytopenia and stomatitis occurred in 1 case. The response rate was 23%, the disease control rate was 69%, and the median relapse-free survival time was 4 months(1-14). OX combination therapy for unresectable or recurrent gastric cancer was feasible in terms of safety and might be effective for disease control.

    Japanese, Scientific journal, Sorafenib is the first molecularly targeted drug recommended as a treatment for advanced hepatocellular carcinoma (HCC). Herein, we report the efficacy of sorafenib for extrahepatic recurrence of HCC. From September 2004 to March 2015, 47 patients who were diagnosed with recurrent HCC after liver resection were treated with sorafenib. The overall response rate was 17.5% (complete response: CR 1, partial response: PR 6, stable disease: SD 17, progressive disease: PD 13, SD beyond PD 3), and the disease control rate was 67.5%. The median time to disease progression, including extrahepatic recurrence, was significantly better than in the group with only intrahepatic metastasis (p=0.034).

    English, Scientific journal, A 36-year-old man who presented with a nosebleed and anemia was referred to our hospital. Laboratory test results showed platelet depletion, decreased levels of fibrinogen, and increased fibrinogen degeneration products. CT showed a 13-cm splenic tumor. T2 -weighted MRI revealed a high-intensity mass. We preoperatively diagnosed splenic hemangioma with chronic disseminated intravascular coagulation and scheduled an operation to relieve the disseminated intravascular coagulation. We also performed hand-assisted laparoscopic splenectomy to ensure easy handling of the splenomegaly. The resected specimen microscopically consisted of hemorrhages and hemangiomatous lesions, and multiple angiomatoid nodules were scattered and separated by fibrocollagenous stroma with inflammatory cells. Three types of vessels (capillaries, sinusoids and small veins) were contained in the angiomatoid nodules, and the pathological diagnosis was sclerosing angiomatoid nodular transformation. The results of this case suggest that we should consider sclerosing angiomatoid nodular transformation in the differential diagnosis of patients with splenic tumors, as sclerosing angiomatoid nodular transformation with hemangiomatous features may cause coagulation disorders for which splenectomy should be performed.

    Japanese, Scientific journal, A 64-year-old man with hepatocellular carcinoma located in the left lateral lobe and segment 5 was referred to our hospital for surgical treatment. We performed left lateral sectionectomy and segmentectomy 5. The pathological diagnosis was moderately to poorly differentiated hepatocellular carcinoma, and the pathological stage was stage III. Eight months later, intrahepatic recurrence in segment 1 and lymph node metastasis in the hepatoduodenal ligament occurred. Partial resection of segment 1 was performed, and the metastatic lymph node was surgically removed. Twenty four months after the first operation, lymph node metastases along the lesser curvature and retropancreatic space were extirpated. Lymph node metastases along the common hepatic artery were removed 76 months after the first operation. The patient developed jaundice 88 months after the initial surgery, and the bile duct tumor thrombus derived from intrahepatic recurrence in segment 1 caused obstructive jaundice. After percutaneous transhepatic biliary drainage, we performed median sectionectomy and bile duct tumor thrombus removal without bile duct resection. At his 8-year follow-up visit after the primary operation, the patient was healthy and did not show any signs of recurrence. Lymph node metastasis and bile duct tumor thrombus are rare patterns of hepatocellular carcinoma recurrence, and aggressive surgery can result in long-term survival when complete resection is anticipated.

    Gan to kagaku ryoho. Cancer & chemotherapy, 38, 12, 2481, 2483, 12, Nov. 2011, [Peer-reviewed], [Domestic magazines]
    Japanese, Scientific journal, For recurrent hepatic tumors with treatment history or cirrhosis, small region including extrahepatic tumors that cannot be identified on routine ultrasonography, we used a fluorescent imaging with indocyanine green (ICG) for repeated resection of hepatocellular carcinoma. The patients were consisted of 4 men and 2 women with a mean age of 61.5 (37-66) years. Five cases of intra or extra hepatic tumors could be identified with fluorescent imaging system. Two cases were a local recurrence after TACE, 1 case was a small tumor exited in liver surface, 1 case could be identified the area of vascular invasion of subcutaneous recurrence, and 1 case was a mediastinal small lymph node metastasis of hepatocellular carcinoma. Fluorescent imaging using ICG was considered to be useful for identification of recurrent hepatocellular carcinoma that cannot be identified by a routine ultrasonography.

    Surgery today, 41, 9, 1252, 4, Sep. 2011, [Domestic magazines]
    English, Scientific journal, Abdominal wound dehiscence is a serious complication of laparotomy, and fascial dehiscence in a patient with a stoma is especially difficult to manage. We describe how we performed local skin flap reconstruction for abdominal wound dehiscence in two patients with stomas. One patient underwent sigmoidectomy with a colostomy for peritonitis caused by perforated diverticulitis of the sigmoid colon. Postoperative fascial dehiscence was repaired by rhomboid flap reconstruction. The other patient underwent total gastrectomy, cholecystectomy, and splenectomy. An ileostomy was performed for digestive tract perforation, which was complicated by abdominal dehiscence with necrosis of the fascia. This was repaired by rotation flap reconstruction. The abdominal walls in both patients were repaired successfully without tension.

    The mortality rate of pancreatic adenocarcinoma is the highest among all cancer types, because of a lack of specific symptoms in the early stages, limitations of diagnostic methods, and the lack of response to all present treatments. We conducted plasma proteomics to identify the plasma proteins, the expression of which is aberrantly regulated in pancreatic cancer, in order to develop the specific and sensitive tumor markers for early diagnosis. To reduce the complexity and dynamic range of plasma proteome, we combined multi-dimensional liquid chromatography with 2D-PAGE. In our system, highly abundant proteins were depleted by Multiple Affinity Removal Column (Agilent) and the flow through fraction was separated by anion exchange column. For accurate quantitative comparison of protein expression profiles, the fractioned proteins were labeled with fluorescent dyes, which were developed for two-dimensional difference gel electrophoresis (2D-DIGE). The number of protein spots was increased from 290 to 403 spots by depleting the abundant proteins, then further increased up to 1098 by fractionation with anion exchange chromatography, provably due to the reduced complexity and dynamic range of plasma proteome. We selected 39 protein spots, whose intensity was significantly different in amount by more than 2-fold between the patients with pancreatic cancer and the healthy volunteers. The proteins corresponding to the selected protein spots were determined by mass spectrometry, and the identification of the proteins was confirmed by specific antibodies. A combination of multi-dimensional liquid chromatography with 2D-PAGE is a powerful tool for plasma proteomics. The identified proteins will be a candidate for diagnostic tumor marker and provide a clue to understand the molecular background of pancreatic cancer.

    これまでの糖鎖解析を行う癌に関する研究は、患者血清を用いるものが多かったが、患者背景:併存する疾患、人種などの影響があり、癌細胞上で行われる糖鎖修飾がどのように癌細胞の生物学的な悪性度を関連性があるかは未解決である。肝癌細胞株での実験で、これまで報告された患者血清から検出された糖鎖と異なるものが、浸潤能に関与していることが分かったため、実際の切除検体である癌細胞組織での検討が必要であるとの考えに至った。
    今年度は、実際の切除検体である癌細胞組織での糖鎖解析による検討を行った。2001年から2006年までの肝細胞癌切除例48例の凍結検体の網羅的糖鎖解析による糖鎖発現を全自動血清糖鎖プロファイル解析で行った。1325.55m/zから3336.24m/zまでの39個の糖鎖を検出でき、肝癌組織のN型糖鎖プロファイルを解析できた。凍結保存された肝細胞癌切除標本の糖鎖解析が普遍的に可能であることが検証された。今後、同一患者さんで、非癌部の肝組織、血清での発現と、今回検出できた糖鎖との関連性を検証していく。さらにこれらの結果と臨床病理学的所見・組織病理学的所見、切除後の予後・再発との関連性を検討する予定であり、実際の肝細胞癌組織と癌悪性度、浸潤能などとの関連性がある特異の糖鎖が発見され、この糖鎖修飾を阻害することができる阻害剤が見つかれば、創薬の点からも癌治療に大きく貢献できると確信している。肝切除かあるいは分子標的薬による薬物治療かの治療選択基準となりうる新規バイオマーカーを検出できる可能性がある。

    The prognosis of pancreatic cancer (PC) is extremely poor and it is difficult to diagnose PC in early stage. We analyzed leucine-rich alpha-2-glycoprotein (LRG) in serum as a new diagnostic marker of PC. We used the serum of PC patients (n=68) and healthy volunteer (n=10) and analyzed the serum concentration of LRG by ELISA. We found that LRG levels of PC patients in all stages were significantly up-regulated compared with those of healthy volunteers. Moreover, LRG concentrations were highly expressed in 22 of 25 PC patients whose serum levels of CA19-9 were low. LRG is a candidate of new diagnostic marker of PC. We plan to isolate LRG from serum and analyze differentially expressed glycans of LRG in future research.

    We previously reported that adenomatous polyposis coli-binding protein EB1 (EB1) is overexpressed in HCC tissues by proteomics. In present study, ①EB1 expression significantly correlated with the degree of histological differentiation, AFP, vascular invasion status in HCC patients. Moreover, overall survival and recurrence rate was significantly poor in EB1-high expressed HCC patients. ②EB1 promoted cell proliferation, migration, invasion, tumor growth in HCC cell lines. ③Microarray analysis revealed that EB1 might regulate the expression level of Dlk-1. As a conclusion, EB1 may become a new biomarker of HCC and a potential molecular target of HCC therapy.

    We analyzed the correlation between the expression of FABP5 and malignant behavior of HCC using HCC tissues and cell lines. A total of 243 HCC samples were subjected to immunohistochemistry, and protein expression of FABP5 in HCC cell lines was assessed by Western blot. The intensity of immunostaining in HCC tissues were divided into a strong staining group and a weak staining group. In the strong group, 5-year overall survival rate was 59.5%, compared with 89.9% in the weak group , and 5-year relapse free survival rate in the strong group was 23.7%, compared with 47.2% in the weak group . In vitro, Western blot showed protein expression of highly invasive cell lines was high, while lowly invasive cell was low. The knockdown of FABP5 in highly invasive cell lines also inhibited cell proliferation, migration and invasiveness significantly. FABP5 was closely related with malignancy, and also behaved as a significant prognostic and recurrence factor for HCC patients.
