Gallbladder carcinoma (GBC) is the most common biliary tract malignancy with high mortality. The median survival time is 6 months, and the 5-year survival rate less than 5% for GBC patients. Thus, it is imperative to investigate the molecular mechanisms underlying the pathogenesis of GBC. miR-133a may exert anti-tumor effects on a variety of cancers. However, the role of miR-133a in the pathogenesis of GBC remains unclear. In this study, quantitative real-time polymerase chain reaction (qRT-PCR) showed the miR-133a-3p expression markedly decreased in GBC as compared to adjacent normal tissues...

Intrahepatic cholangiocarcinoma (ICC) is an aggressive and lethal malignancy with limited therapeutic options. Trabectedin has a high antitumor activity in preclinical models of biliary tract carcinoma (BTC), being a promising alternative treatment. Here, we studied the effect of trabectedin at transcriptomic level on an ICC patient derived xenograft (PDX) and on the derived cell line, MT-CHC01. Further, putative targets of trabectedin were explored in the in vitro model. In vitro, trabectedin inhibited genes involved in protein modification, neurogenesis, migration, and motility; it induced the expression of genes involved in keratinization, tissues development, and apoptotic processes...

Gallbladder cancer (GBC) is the most common and aggressive form of biliary tract carcinoma with an alarmingly low 5-year survival rate. Despite its high mortality rate, the underlying mechanisms of GBC pathogenesis are not completely understood. Recently, from a growing volume of literature, long non-coding RNAs (lncRNAs) have emerged as key regulators of gene expression and appear to play vital roles in many human cancers. To date, a number of lncRNAs have been implicated in GBC, but their potential roles in GBC have not been systematically examined...

BACKGROUND AND AIMS: The incidence of gallstones and gallbladder sludge is higher in patients after total gastrectomy than in general population. Formation of gallstones after gastrectomy is multifactorial. Here, we investigate the changes in gallbladder and biliary tract functions by cholescintygraphy and monitored changes in cholecystokinin (CCK) release in long-term survivors after total gastrectomy for gastric carcinoma. MATERIAL AND METHODS: Patients had undergone total gastrectomy for gastric carcinoma at least five years ago...

Advanced biliary tract cancers (ABTC) are among the deadliest malignancies with limited treatment options after progression on standard-of-care chemotherapy, which includes gemcitabine (GEM) and oxaliplatin (OX). The epidermal growth factor receptor inhibitor erlotinib has been explored in ABTC with modest efficacy. Erlotinib given continuously may antagonize the action of chemotherapy against cycling tumor cells, but pulsatile dosing of erlotinib with chemotherapy may improve efficacy. The purpose of this study was to assess the safety of pulsatile erlotinib with GEMOX...

We recently reported several driver genes of biliary tract carcinoma (BTC) that are known to play important roles in oncogenesis and disease progression. Although the need for developing novel therapeutic strategies is increasing, there are very few BTC cell lines and xenograft models currently available for conducting preclinical studies. Using a total of 88 surgical BTC specimens and 536 immunodeficient mice, 28 xenograft models and 13 new BTC cell lines, including subtypes, were established. Some of our cell lines were found to be resistant to gemcitabine, which is currently the first choice of treatment, thereby allowing highly practical preclinical studies to be conducted...

Biliary tract cancers (BTC) are malignancies that arise from the epithelium of the biliary system and comprise the second most common type of hepatobiliary cancer worldwide. BTC are sub-classified as intrahepatic cholangiocarcinoma (iCCA), perhilar/hilar cholangiocarcinoma (pCCA), distal cholangiocarcinoma (dCCA), and gallbladder carcinoma. Due to the differences in their etiologic risk factors, pathogenesis, and molecular and genetic characteristics, each of these subtypes is considered a separate biological entity...

INTRODUCTION: The over-expression of P53 protein in gallbladder carcinoma is a biomarker correlating with a poor survival. However, the significance of P53 expression in peritumor tissues is unknown. We experienced a case of gallbladder carcinoma where the operative specimen showed over-expression of P53 on the peritumor epithelium, and early recurrence developed at the biliary tract. PRESENTATION OF CASE: A 74-year-old female patient was referred to our hospital due to wall thickening of the gallbladder on ultrasonography...

Cholangiocarcinoma (CCA) is an epithelial cell malignancy arising from bile ducts and/or peribiliary glands. Even though it is considered as a rare neoplasm, its incidence is raising, particularly in developed countries. Prognosis is generally poor with few patients who present the inclusion criteria for surgery (the mainstay treatment for this tumour). Several genetic alterations potentially driving tumour progression have been described, representing a possible target for new compounds. Areas covered: A clinical trial search in Clinicaltrials...

INTRODUCTION: For carcinoma of the ampulla of Vater, lymph node metastasis around the abdominal aorta is an inoperable factor equivalent to distant metastasis, such as hepatic metastasis or peritoneal carcinomatosis, making the cancer unresectable. PRESENTATION OF CASE: A 53-year-old man was referred to our hospital and was diagnosed as having carcinoma of the ampulla of Vater with lymph node metastases around the abdominal aorta. Although only chemotherapy was initially scheduled, the chemotherapy was effective, and the metastases were dramatically reduced after 4 cycles of chemotherapy...

BACKGROUND/PURPOSE: Cholangiocarcinoma (CC) is a fatal malignancy originating from biliary tracts and constitutes approximately 10-20% of hepatobiliary cancers. CC is characterized by a very poor prognosis. The definite molecular mechanisms leading to oncogenesis remain unclear. This study aimed to perform mutation analysis and copy number changes of KRAS and BRAF genes of CC in Taiwan. METHODS: A total of 182 cases of biliary tact CC were studied for point mutation and quantitative real-time polymerase chain reaction analysis of KRAS and BRAF genes...

PURPOSE: Progranulin (PGRN), characterized as an autocrine growth and survival factor, is known to stimulate the proliferation and survival of several cancer cell types. However, little is known about the prognostic role of PGRN in advanced biliary tract cancers (BTCs). METHODS: A retrospective analysis was performed on patients with advanced BTC who received palliative chemotherapy between July 2004 and November 2014. PGRN expression was immunohistochemically evaluated according to staining intensity of tumor and peritumoral cells...

BACKGROUND: Hepatocyte Paraffin 1 (Hep Par 1) was being extensively used to recognize the hepatocellular carcinomas, until recognition of its expression in tumors without hepatocellular differentiation. AIMS AND OBJECTIVES: The aim of this study was to analyze if Hep Par 1 stain can serve as a specific marker of the small intestinal (SI) adenocarcinomas, versus other gastrointestinal tract (GIT) primary tumors. MATERIALS AND METHODS: In this retrospective cross-sectional study, normal GIT mucosa (n - 60), corresponding adenocarcinomas (n - 60) and nodal metastatic foci (n - 60) from the same patients, including 10 cases each from the esophagus, stomach, SI periampullary region, colon, rectum, and gall bladder were included...

Pancreaticobiliary maljunction (PBM) is a congenital malformation in which the pancreatic and bile ducts join anatomically outside the duodenal wall. Because of the excessive length of the common channel in PBM, sphincter action does not directly affect the pancreaticobiliary junction, which allows pancreatic juice to reflux into the biliary tract. According to the results of a nationwide survey, bile duct and gallbladder cancers were found in 6.9 and 13.4 % of adult patients with congenital biliary dilatation, respectively, and in 3...

Andres M Acosta, Elizabeth Louise Wiley
Mixed adenoneuroendocrine carcinomas (MANECs) are composite neoplasms with areas of adenocarcinoma or squamous cell carcinoma intermingled with neuroendocrine carcinoma or neuroendocrine tumor, each composing at least 30% of the neoplasm. MANECs are very infrequent overall, and they are more commonly diagnosed in the appendix, colon, and stomach. Biliary MANECs are particularly rare, and their histogenesis is debated because neuroendocrine cells are seldom identified in the normal biliary tract. They can show one of the 3 different architectural patterns described in Lewin's original classification: collision tumors, combined lesions, or amphicrine neoplasms...

REVIEW
Thomas B Brunner, Thomas Seufferlein
Cholangiocarcinoma can arise in all parts of the biliary tract and this has implications for therapy. Surgery is the mainstay of therapy however local relapse is a major problem. Therefore, adjuvant treatment with chemoradiotherapy was tested in trials. The SWOG-S0809 trial regimen of chemoradiotherapy which was tested in extrahepatic cholangiocarcinoma and in gallbladder cancer can currently be regarded as highest level of evidence for this indication. In contrast to adjuvant therapy where only conventionally fractionated radiotherapy plays a role, stereotactic body radiotherapy (SBRT) today has become a powerful alternative to chemoradiotherapy for definitive treatment due to the ability to administer higher doses of radiotherapy to improve local control...
