Immunotherapy is a potentially attractive treatment option for patients with hepatocellular carcinoma (HCC). We have reported that glypican-3 (GPC3) is an ideal target for anticancer immunotherapy against HCC because its expression is specifically detected in > 80% of HCCs, even during the early stages. Further, increased GPC3 expression is correlated with a poor prognosis. Based on results obtained from a preclinical study using mice, we conducted a phase I clinical trial using a GPC3-derived peptide vaccine. Phase I results showed that the GPC3-derived peptide vaccine was well tolerated. Furthermore, this was the first study to show that the frequency of peptide-specific cytotoxic T lymphocytes was correlated with overall survival in patients with HCC receiving a peptide vaccine. Next, we conducted a phase II clinical trial using the GPC3-derived peptide vaccine in patients with HCC after surgery or radiofrequency ablation (adjuvant setting). We are currently evaluating a third trial involving liver biopsies removed from patients with advanced HCC before and after GPC3-derived peptide vaccination. We expect that the results of these trials will result in future drug development.

Adenovirus serotype 5 (Ad5) is frequently used as an effective vector for induction of therapeutic transgenes in cancer gene therapy or of tumor cell lysis in oncolytic virotherapy. Ad5 can infect target cells through binding with the coxsackie and adenovirus receptor (CAR). Thus, the infectious ability of Ad5-based vectors depends on the CAR expression level in target cells. There are conventional methods to evaluate the CAR expression level in human target cells, including flow cytometry, western blotting and immunohistochemistry. Here, we show a simple system for detection and assessment of functional CAR expression in human tumor cells, using the green fluorescent protein (GFP)-expressing telomerase-specific replication-competent adenovirus OBP-401. OBP-401 infection induced detectable GFP expression in CAR-expressing tumor cells, but not in CAR-negative tumor cells, nor in CAR-positive normal fibroblasts, 24 h after infection. OBP-401-mediated GFP expression was significantly associated with CAR expression in tumor cells. OBP-401 infection detected tumor cells with low CAR expression more efficiently than conventional methods. OBP-401 also distinguished CAR-positive tumor tissues from CAR-negative tumor and normal tissues in biopsy samples. These results suggest that GFP-expressing telomerase-specific replication-competent adenovirus is a very potent diagnostic tool for assessment of functional CAR expression in tumor cells for Ad5-based antitumor therapy.

New Surgical Approach to Large Splenorenal Shunt in Living Donor Liver Transplantation: Diversion of SMV and SPV Blood Flow

Journal of Gastrointestinal Surgery 17 ( 2 ) 403 - 407 2013

Language：English

Introduction: The management of a large splenorenal shunt is important because it affects recipient outcome, particularly in living donor liver transplantation. Methods: To manage large splenorenal shunts in living donor liver transplantation, we diverted superior mesenteric vein and splenic portal vein blood flow by ligation at the root of the splenic portal vein. Result: This procedure was applied for five patients in whom superior mesenteric vein blood flow had been completely stolen by a splenorenal shunt preoperatively. Postoperative course was excellent in all cases. Conclusion: This technique completely prevents morbidity related to large splenorenal shunts after living donor liver transplantation. © 2012 The Society for Surgery of the Alimentary Tract.

TWO CASES OF DIAPHRAGMATIC HERNIA FOLLOWING PERCUTANEOUS RADIOFREQUENCY ABLATION FOR HEPATOCELLULAR CARCINOMA

Language：Japanese Publisher：Japan Surgical Association

Reports of diaphragmatic hernia associated with radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) are rare. We report 2 cases of diaphragmatic hernia that developed after RFA for HCC. Case 1 involved a 65-year-old man who had undergone percutaneous RFA for HCC located in the S5 and S7 areas. Three years later, he underwent surgery from the abdominal cavity side based on the diagnosis of right diaphragmatic hernia made by another hospital. One year later, the right diaphragmatic hernia recurred, necessitating the performance of video-assisted thoracic surgery at our hospital. The defect of the diaphragm was covered with mesh. Case 2 involved a 73-year-old woman who had undergone percutaneous RFA for HCC located in the S7 area. Subsequently, she underwent 3 sessions of RFA for HCC localized in the S3, S1, and S4 areas. Seven years after the first RFA, right diaphragmatic hernia occurred, and we performed surgery via thoracotomy. The defect of the diaphragm was repaired by direct suture. The thoracotomic approach may be a safe and useful option for the treatment of diaphragmatic hernia after RFA.
