BACKGROUND: The aim of this study was to evaluate the clinical significance of preoperative classification of intrahepatic cholangiocarcinoma (ICC) into perihilar and peripheral types using dynamic computed tomography (CT). PATIENTS AND METHODS: A retrospective cohort study was performed to analyze the differences in clinical characteristics between perihilar and peripheral ICC samples from patients between 1990-2014. RESULTS: A total of 87 patients were divided into three ICC subtypes; perihilar (n=34), peripheral (n=44), and unclassifiable ICC (n=9)...

Agostino Di Ciaula, Valerio Gennaro
The recent finding of asbestos fibres in drinking water (up to 700.000 fibres/litres) in Tuscany (Central Italy) leads to concerns about health risks in exposed communities. Exposure to asbestos has been linked with cancer at several levels of the gastrointestinal tract, and it has been documented, in an animal model, a direct cytotoxic effect of asbestos fibres on the ileum. It has been recently described a possible link between asbestos and intrahepatic cholangiocarcinoma, and asbestos fibres have been detected in humans in histological samples from colon cancer and in gallbladder bile...

Intrahepatic cholangiocarcinoma (ICC) is a rare yet deadly malignancy with limited treatment options. Activation of the Notch signalling cascade has been implicated in cholangiocarcinogenesis. However, while several studies focused on the Notch receptors required for ICC development, little is known about the upstream inducers responsible for their activation. Here, we show that the Jagged 1 (Jag1) ligand is almost ubiquitously upregulated in human ICC samples when compared with corresponding non-tumorous counterparts...

Oriental cholangiohepatitis is a condition occurring in the Asian population, characterised by recurrent bacterial cholangitis and presence of calculi within the intrahepatic bile ducts, biliary strictures and an increased risk for cholangiocarcinoma. It is an uncommon disease in the West that may not always be considered. The therapeutic approach is multidisciplinary and highly individual, and includes antibiotic therapy, endoscopic and percutaneous biliary drainage with stone removal and dilation of strictures, and in selected cases surgical resection of affected liver segments...

INTRODUCTION: Primary neuroendocrine tumors (NET) of the extrahepatic biliary tree are a rare entity with less than 100 reported cases in the literature. PRESENTATION OF CASE: Here, we report a case of NET of the extrahepatic bile duct in a 64-year-old male patient presenting with painless jaundice, direct hyperbilirubinemia, and mildly elevated transaminases. Diagnostic workup with an ultrasound revealed dilation of the intrahepatic biliary ducts, without cholelithiasis or choledocholithiasis...

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...

Background: Intrahepatic cholangiocarcinoma (IHCCA) is an aggressive tumor for which surgical resection is a mainstay of treatment. However, recurrence after resection is common associated with a poor prognosis. Studies regarding recurrence of mass-forming IHCCA are rare; therefore, we investigated the pattern with our dataset. Methods: We retrospectively reviewed the medical and pathological records of 50 mass-forming IHCCA patients who underwent hepatic resection between January 2004 and December 2009 in order to determine the patterns of recurrence and prognosis...

OBJECTIVES: Vascular endothelial growth factor overexpression, seen in 42% to 76% of biliary tract cancers (BTCs), correlates with poor survival. We explored the safety/efficacy and potential biomarkers for bevacizumab in combination with gemcitabine-capecitabine in advanced BTCs. PATIENTS AND METHODS: Inoperable stage III/IV BTC patients in our prospective study were given 1000 mg/m of gemcitabine (on days 1, 8), 650 mg/m of capecitabine (on days 1 to 14), and 15 mg/kg of bevacizumab (on day 1) in 21-day cycles...

IgG4-related disease represents a heterogeneous group of disease characterized by infiltration of various tissues by IgG4 plasmocytes. In case of liver infiltration, this condition classically mimics primary sclerosing cholangitis or multifocal cholangiocarcinoma due to inflammation that preferentially affects the intra- and extrahepatic bile duct. Diagnostic criteria have recently been reviewed in order to better define the disease and help physicians make the diagnosis. Herein, we present the case of a patient who died after liver surgery for suspected cholangiocarcinoma that finally turned out to be IgG4-associated liver disease, a condition being out of current consensual criteria...

BACKGROUND: Decrease in skeletal muscle mass and function, known as sarcopenia, is associated with poor prognosis. Visceral fat accumulation also is related to mortality. This study investigated the impact of preoperative skeletal muscle mass, muscle quality, and visceral adiposity on outcomes in patients undergoing resection of intrahepatic cholangiocarcinoma (ICC). METHODS: A retrospective analysis was performed of 109 patients undergoing resections of ICC between January 2004 and April 2015...

Hepatic stem/progenitor cells (HPC) reside quiescently in normal biliary trees and are activated in the form of ductular reactions during severe liver damage when the replicative ability of hepatocytes is inhibited. HPC niches are full of profibrotic stimuli favoring scarring and hepatocarcinogenesis. The Cyr61/CTGF/NOV (CCN) protein family consists of six members, CCN1/CYR61, CCN2/CTGF, CCN3/NOV, CCN4/WISP1, CCN5/WISP2, and CCN6/WISP3, which function as extracellular signaling modulators to mediate cell-matrix interaction during angiogenesis, wound healing, fibrosis, and tumorigenesis...

Hepatocellular carcinoma (HCC), the fifth most common cancer globally and third leading cause of cancer-related mortality is a heterogeneous disease with a highly variable clinical course. The inherent biological diversity of hepatic carcinomas may hinder therapeutic decision making and prognostication for patients. One distinct, albeit rare, subtype of primary hepatic carcinoma is combined intrahepatic cholangiocarcinoma and hepatocellular carcinoma (cHCC-ICC), which carries an overall worse prognosis than either HCC or intrahepatic cholangiocarcinoma (ICC) alone...

Biliary tract cancers represent an uncommon, heterogenous malignant group of tumors that include gallbladder cancers (GBC) and cholangiocarcinomas that are frequently detected in the locally advanced or metastatic setting. The randomized phase III ABC-02 trial established the combination regimen of cisplatin plus gemcitabine as standard of care therapy. Nevertheless, despite prior and subsequent attempts utilizing a variety of treatment strategies clinical outcomes for these cancers remains disappointing, necessitating the innate call for improvements in treatment approaches...

Biliary tract cancers (BTC) are aggressive gastrointestinal malignancies that are associated with a poor prognosis. This rare group of tumors includes cancers of the gallbladder, intrahepatic, and extrahepatic biliary tree. Chronic inflammatory processes such as cholelithiasis and chronic bacterial infection of the biliary system remain the most common underlying risk factor although most cases occur sporadically. The majority of patients present with advanced disease accompanied by nonspecific symptoms, making BTCs a therapeutic challenge for clinicians...

The pathology of biliary carcinomas is diverse with different gross and histological features in tumors arising in the different segments of the biliary system. Various epidemiological risk factors, varied genetic makeup, and tissue microenvironment are contributory factors. As biliary tumors have been shown to be a part of the Lynch syndrome tumor spectrum, it is plausible to speculate that DNA mismatch repair (MMR) deficiency plays a role in biliary tumors. Literature data suggest that DNA MMR deficiency indeed occurs in these tumors, albeit infrequently with the reported frequencies (weighted for sample size) of high level microsatellite instability (MSI) being 5% each for gallbladder carcinoma and carcinoma of extra-hepatic bile ducts, and 10% each for intrahepatic cholangiocarcinoma and ampullary carcinoma...
