 The Department of Hepatobiliary and Pancreatic Oncology treats tumors originating from the liver, biliary system or pancreas, which include hepatocellular carcinoma (HCC), biliary tract cancer and pancreatic cancer. As part of the multi-disciplinary care given at the National Cancer Center Hospital (NCCH), we work closely with surgeons and radiologists who have special expertise in these areas. We also conduct research into the pathophysiology of hepatobiliary and pancreatic tumors and seek to develop new and more effective diagnostic methods and treatments.

The Team and What We Do

 The Department consists of five staff oncologists and several residents. We have used percutaneous ablation therapy as a valuable alternative to surgery for most patients with three or fewer HCC nodules, all of which are smaller than 3 cm in diameter. We also perform transcatheter arterial chemoembolization (TACE), mainly in patients with multiple HCC nodules. Systemic or intra-arterial chemotherapeutic regimens are indicated in advanced HCC patients for whom locoregional intervention and surgery are unsuitable or had been unsuccessful. In patients with unresectable pancreatic cancer or biliary tract cancer, chemotherapy is performed in clinical practice or as a clinical trial to develop active treatment. We have actively introduced endoscopic procedures for imaging diagnosis (endoscopic ultrasonography: EUS, endoscopic retrograde cholangiopancreatography: ERCP), tumor biopsy (EUS-guided fine needle aspiration: EUS-FNA), and biliary drainage including EUSguided hepaticogastrostomy (EUS-HGS) and EUS-guided choledochoduodenostomy (EUSCDS) (Tables 1 & 2).

Research activities

 We published 12 papers as a first author in peer-reviewed journals in 2018.

 The precise proportion of PC patients harboring DNA mismatch repair genes (MMR genes) remains unclear. Among 304 Japanese patients with pathologically proven pancreatic ductal adenocarcinoma, Ohmoto et al. selected 20 (6.6%) patients with a personal or family history involving first- or second-degree relatives fulfilling the revised Bethesda guidelines (RBG), defined as RBG-compatible cases. We analyzed germline variants in 21 genes related to a hereditary predisposition for cancer as well as clinical features in all 20 cases. The RBGcompatible cases did not show any unique clinicopathological features. Targeted sequencing data revealed three patients carrying deleterious or likely deleterious variants. Specifically, these three patients harbored a nonsense variant in ATM, a frameshift variant in ATM, and a concurrent nonsense variant in PMS2 and missense variant in CHEK2 (double-mutation carrier), respectively. Although an MMR gene mutation was identified in only one of the 20 patients, up to 15% of the RBG-compatible PC cases were associated with germline deleterious or likely deleterious variants.

 Biliary tract carcinoma (BTC) is an extremely malignant tumor, but available treatment options are limited. Despite of needs for novel therapies, few BTC-related resources are currently available for evaluation of candidate drugs. To address this issue, Sakamoto et al. have recently established 13 cell lines from surgical specimens from Japanese BTC patients. Four new molecular targeting agents were evaluated using our BTC cell-based assay panel with 17 BTC cell lines. PI3K/mTOR dual inhibitor LY3023414 showed activity at submicromolar concentration ranges against 13 of the 17 cell lines tested, including the ones with gemcitabine insensitivity. In conclusion, we demonstrated that in vitro study with the BTC cell line panel would be an efficient approach to screen for novel therapeutic strategies. Although this is a preliminary result and further investigations are required for confirmation, PI3K/mTOR inhibitor might be a potential target for BTC drug development.

Clinical trials

 26 clinical trials are ongoing, including one phase I trial, twelve phase II trials, ten phase III trials such as adjuvant chemotherapy after resection versus resection alone for patients with resectable tumors, and chemotherapy with a new regimen versus standard therapy for patients with advanced tumors, and 4 registration trials. Our studies are supported by the National Cancer Center Research and Development Fund (Grant No. 29-A-3), Project for Development of Innovative Research on Cancer Therapeutics 17ck0106350h0001, 17ck0106355h0001, 17ck0106354h0001) from the Japan Agency for Medical Research and Development.


 Our staff members are working closely with residents to support their skill development and knowledge expansion in both clinical and research fields. We are conducting conferences daily for clinical practice and weekly for research development. The residents in our department published five papers as a first author in peerreviewed journals in 2018, and are performing 18 ongoing studies as a leading researcher, with assistance from staff members.

Future prospects

 Our department keeps providing best and latest diagnosis, treatment and supportive care, and developing their more effective methods and techniques for all patients with hepatobiliary and pancreatic cancer in this country and all over the world. Among them, conducting clinical trials with novel promising agents for this disease is considered one of the most important tasks, and establishment of cutting-edge endoscopic procedures in this field is the most significant mission for us.
