BACKGROUND: Biliary tract cancers are a group of rare heterogeneous malignant tumours. They include intrahepatic and extrahepatic cholangiocarcinomas, gallbladder carcinomas, and ampullary carcinomas. Surgery remains the optimal modality of therapy leading to long-term survival for people diagnosed with resectable biliary tract carcinomas. Unfortunately, most people with biliary tract carcinomas are diagnosed with either unresectable locally-advanced or metastatic disease, and they are only suitable for palliative chemotherapy or supportive care...

Cancers of the bile ducts or cholangiocarcinomas are a rare entity whose incidence is increasing in France. Surgical resection of cholangiocarcinoma remains the only curative therapy. Adjuvant therapy with capecitabine at a fixed dose of 1250mg/m2 twice daily from day 1 to day 14 (21-day cycle) for a 6 months period is now the standard of care after curative surgery. At a metastatic stage, the reference treatment consists of the combination of a platinum salt in addition to gemcitabine. No biomarker has been identified to predict the response to chemotherapy...

Hepatocellular carcinoma (HCC) and biliary tract cancer (BTC) are more frequent in East Asia including Japan. Compiling 1,340 multi-ethnic HCC genomes, the largest cohort ever reported, identified comprehensive landscape of HCC driver genes, which constitutes three core drivers (TP53, TERT and WNT signaling) and combination of infrequent alterations in various cancer pathways. By contrast, five core driver genes (TP53, ARID1A, KRAS, SMAD4 and BAP1) with characteristic molecular alterations including fusion transcripts involving FGFR2 and the PKA pathway, and IDH1/2 mutation constituted the BTC genomes...

Gallbladder cancer (GBC) is the most general biliary tract malignancy, with poor prognosis due to rapid tumor progression and lack of specific symptoms. Lactate dehydrogenase-A (LDHA) can promote Warburg effect to produce lactate and Adenosine Triphosphate (ATP) in aerobic condition, which contributes to oncogenesis metastasis and drug resistance in various cancers. However, the expression and functional role of LDHA in GBC are largely unknown. We determined that LDHA was over-expressed in GBC tumor tissues compared with normal tissues, which was also an independent prognostic factor for the overall survival of GBC patients by tissue microarrays analysis...

BACKGROUND: Recent studies have reported TIMs play an important role in tumors progression or regression, but the effect of TIMs in biliary tract cancer remains unclear. The aim of this study is to investigate the prognostic value of tumor infiltrating mast cells (TIMs) and its influence on gemcitabine-based adjuvant chemotherapy (ACT) benefits in biliary tract cancer patients after surgery. METHODS: TIMs were evaluated by immunohistochemical staining of tryptase in 250 patients with resected gallbladder carcinoma (GBC) or extrahepatic bile duct carcinoma (EBDC) from Zhongshan Hospital...

Bronchobiliary fistula (BBF) is a rare condition, defined as an abnormal communication between the bronchial system and the biliary tree. Patients with this condition usually present with massive biliptysis, and the mortality rate is high. BBF has been reported to occur in patients with congenital conditions, complications of trauma, hepatic abscesses and biliary tract obstruction (surgical as well as non-surgical). However, to the best of our knowledge, BBF as a complication of transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC) has not been reported to date...

Hepatobiliary tract cancers (HBTC) are a heterogeneous group of cancers with high mortality. Because most of these cancers, with the exception of hepatocellular carcinoma (HCC) are rare, few data are available concerning the population level survival expectations of patients with HBTC. Here, we describe survival of patients with HBTC in Germany with comparison to survival in the United States (US). Therefore, data were extracted from 12 databases in Germany and the Surveillance, Epidemiology and End Results (SEER13) database in the US...

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, we have recently established 13 cell lines from surgical specimens from Japanese BTC patients. In the present study, we evaluated four new molecular targeting agents 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...

Worldwide hepatobiliary cancers are the second leading cause of cancer related death. Despite their relevance, hepatobiliary cancers have a paucity of approved systemic therapy options. However, there are a number of emerging therapeutic biomarkers and therapeutic concepts that show promise. In hepatocellular carcinoma, nivolumab appears particularly promising and recently received US FDA approval. In intrahepatic cholangiocarcinoma, therapies targeting FGFR2 and IDH1 and immune checkpoint inhibitors are the furthest along and generating the most excitement...

Pancreatic cancer is the second most common malignancy of the gastrointestinal tract in the US, and adenocarcinoma has been identified as the most common type of pancreatic cancer. Different types of pancreatic cancers have been classified: adenocarcinoma, ductal adenosquamous carcinoma, solid pseudopapillary tumors, endocrine neoplasms, acinar cell carcinoma, squamous cell carcinoma, cystic tumors, primary lymphoma of the pancreas, and metastatic lesions of the pancreas. Adenosquamous carcinoma is extremely rare, behave in a very aggressive way and is responsible for the 1 to 4% of the pancreatic exocrine neoplastic lesions...

Kras mutations are among the most common genetic abnormalities in human neoplasms, including cholangiocarcinomas, pancreatic cancer and colon cancer. PTEN has previously been associated with cholangiocarcinoma development in murine models. Here, we have established novel mouse models of neoplasms by liver-specific and biliary-pancreatic Kras activation and PTEN deletion. By liver-specific disruption of PTEN and activation of Kras in mice caused rapid development of intrahepatic biliary epithelial proliferative lesions (Intrahepatic cholangiocarcinoma, ICC), which progress through dysplasia to invasive carcinoma...

Gallbladder carcinoma (GBC) is one of the common malignancy of the biliary tract. Several genome wide and candidate gene studies have reported associations between multiple cancer types and single-nucleotide polymorphisms on 5p15.33 and 8q24.21 loci. However, predisposition potential of these genetic variants has not been assessed in GBC. We performed the present study to assess the potential of five polymorphisms on 5p15.33 and one on 8q24.21 locus in GBC risk and treatment response in patients undergoing chemoradiotherapy...

An 82-year-old Caucasian woman with a history of basal cell carcinoma on vismodegib presented with nausea, vomiting and intermittent abdominal pain. Laboratory results were remarkable for the elevation of liver enzymes. Endoscopic retrograde cholangiopancreatography and percutaneous transhepatic cholangiogram (PTC) did not show evidence of intrahepatic or extrahepatic obstruction of the biliary tract. During PTC external biliary catheter was placed; however, bilirubin continued to rise. Further, laboratory work-up and imaging studies ruled out other possible aetiologies for hepatotoxicity such as infections, autoimmune hepatitis and other drugs known to be hepatotoxic thus leaving vismodegib the most likely cause of hepatotoxicity...

Gallbladder carcinoma (GBC) is the most common malignancy of the biliary tract with extremely poor prognosis. The malignant transformation of GBC is associated with cell proliferation, invasion, and epithelial-mesenchymal transition (EMT). However, the molecular mechanisms underlying GBC progression are poorly understood. We found that serine threonine tyrosine kinase 1 (STYK1) was elevated in GBC and was negatively correlated with clinical outcomes and prognosis. Overexpression of STYK1 in GBC cell lines gave rise to increased cell proliferation, colony formation, migration and invasion, thus committing cells to undergoing EMT...
