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...

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...

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...

BACKGROUND: While surgery offers the best curative-intent treatment, many patients with biliary tract malignancies have poor long-term outcomes. We sought to apply a non-mixture cure model to calculate the cure fraction and the time to cure after surgery of patients with peri-hilar cholangiocarcinoma (PHCC) or gallbladder cancer (GBC). METHODS: Using the Extrahepatic Biliary Malignancy Consortium, 576 patients who underwent curative-intent surgery for gallbladder carcinoma or peri-hilar cholangiocarcinoma between 1998 and 2014 at 10 major hepatobiliary institutions were identified and included in the analysis...

BACKGROUND: Although gemcitabine and platinum-based agents (GP) are currently regarded as the standard chemotherapy for advanced biliary tract cancer (BTC), the prognosis remains poor. Combinations with fluoropyrimidines and targeted therapy have demonstrated modest benefits. Therefore, we conducted a meta-analysis of randomized controlled trials to evaluate the efficacy of different chemotherapy regimens. METHODS: The PubMed, EMBASE, Cochrane Library, Scopus, and ClinicalTrials...

INTRODUCTION: Primary biliary cholangitis (PBC) is an autoimmune disease of the liver characterized by destruction and inflammation of the intrahepatic bile ducts. The disease affects mainly women. The disease is often discovered through abnormal alkaline phosphatase (ALP) activity, and is confirmed when anti-mitochondrial antibodies (AMA) are present. The etiology of PBC is poorly understood. Cigarette smoking, immune dysregulation, nail polish, urinary tract infections, and low socioeconomic status have been implicated but none have been confirmed...

Biliary tract carcinomas (BTC) are malignant tumors with limited therapeutic options. Clinical experiences with anti-EGFR therapies have produced unsatisfactory results. The strategies of combined inhibition of EGFR and MEK1/2 could be a promising therapeutic option in BTC treatment. Preclinical activity of Panitumumab and Trametinib was tested in in vitro (EGI-1, MT-CHC01 and WITT cells) and in in vivo (xenograft) BTC models with different K-RAS mutational status. Trametinib reduced MAPK phosphorylation in wild type (WT) WITT cells and in both K-RAS mutated cells; in EGI-1 was also able to switch off EGFR activation...

Primary biliary diseases have been associated in several studies with various malignancies. Understanding the risk and optimizing surveillance strategy of these malignancies in this specific subset of patients are an important facet of clinical care. For instance, primary sclerosing cholangitis is associated with an increased risk for cholangiocarcinoma (which is very challenging to diagnose) and when IBD is present for colorectal cancer. On the other hand, primary biliary cirrhosis patients with cirrhosis or not responding to 12 months of ursodeoxycholic acid therapy are at increased risk of hepatocellular carcinoma...

Intraductal papillary neoplasm of the bile duct (IPNB) is a variant type of the bile duct carcinoma characterized by intraductal growth. IPNB is also recognized as a precursor of invasive carcinoma. We describe herein an extremely rare case of IPNB arising from the cystic duct. A 68-year-old man was admitted to our hospital for investigation of epigastralgia and abnormal levels of biliary tract enzyme. Computed tomography and magnetic resonance imaging showed a mass lesion spreading from the cystic duct to the upper-middle bile duct...

BACKGROUND: The development of hepatocellular carcinoma (HCC) is a common consequence of advanced liver fibrosis but the interactions between fibrogenesis and carcinogenesis are still poorly understood. Recently it has been shown that HCC promotion depends on Toll-like receptor (TLR) 4. Pre-cancerogenous events can be modelled in mice by the administration of a single dose of diethylnitrosamine (DEN), with HCC formation depending amongst others on interleukin (IL) 6 production. Mice lacking the hepatocanalicular phosphatidylcholine transporter ABCB4 develop liver fibrosis spontaneously, resemble patients with sclerosing cholangitis due to mutations of the orthologous human gene, and represent a valid model to study tumour formation in pre-injured cholestatic liver...

BACKGROUND: Selenium status is suboptimal in many Europeans and may be a risk factor for the development of various cancers, including those of the liver and biliary tract. OBJECTIVE: We wished to examine whether selenium status in advance of cancer onset is associated with hepatobiliary cancers in the EPIC (European Prospective Investigation into Cancer and Nutrition) study. DESIGN: We assessed prediagnostic selenium status by measuring serum concentrations of selenium and selenoprotein P (SePP; the major circulating selenium transfer protein) and examined the association with hepatocellular carcinoma (HCC; n = 121), gallbladder and biliary tract cancers (GBTCs; n = 100), and intrahepatic bile duct cancer (IHBC; n = 40) risk in a nested case-control design within the EPIC study...
