The identification of the cellular origin of cancer is important for our understanding of the mechanisms regulating carcinogenesis, thus the cellular origin of cholangiocarcinoma (CCA) is a current topic of interest. Although CCA has been considered to originate from biliary epithelial cells, recent studies have suggested that multiple cell types can develop into CCA. With regard to the hilar and extrahepatic bile ducts, peribiliary glands (PBGs), a potential stem cell niche of biliary epithelial cells, have attracted attention as the cellular origin of biliary tract cancer...

Biliary tract cancer, carcinoma of the extrahepatic bile ducts, carcinoma of the gall bladder, ampullary carcinoma and intrahepatic cholangiocarcinoma are often identified at an advanced stage and have poor prognoses. Although effective chemotherapy regimens are needed, their development remains unsatisfactory. From the results of a phase III clinical trial (ABC-02 trial), gemcitabine plus cisplatin is the standard first-line chemotherapeutic regimen for advanced biliary tract cancer. A phase III trial of gemcitabine plus cisplatin vs...

Background: The mortality rates for different cancers are no longer an efficient tool for making national policy. The purpose of this study were to quantify the lifetime risks, life expectancies (LEs) after diagnosis, expected years of life lost (EYLL), and lifetime health care expenditures for 19 major cancers in Taiwan. Methods: A total of 831,314 patients with 19 pathologically proven cancers were abstracted from the Taiwan Cancer Registry from 1998 to 2012. They were linked to the National Mortality Registry (1998-2014) and National Health Insurance reimbursement database (1998-2013) for survival and health care costs...

Immunotherapy using either checkpoint blockade or the adoptive transfer of antitumor lymphocytes has shown effectiveness in treating cancers with high levels of somatic mutations-such as melanoma, smoking-induced lung cancers and bladder cancer-with little effect in other common epithelial cancers that have lower mutation rates, such as those arising in the gastrointestinal tract, breast and ovary1-7 . Adoptive transfer of autologous lymphocytes that specifically target proteins encoded by somatically mutated genes has mediated substantial objective clinical regressions in patients with metastatic bile duct, colon and cervical cancers8-11 ...

BACKGROUND: Double cancers of the biliary tract system are rare. Most of these cancers are synchronous double cancers of the gall bladder and bile duct, associated with pancreaticobiliary maljunction (PBM). Synchronous double cancers of the extrahepatic bile duct without PBM are especially rare, and only 4 cases have been reported. CASE PRESENTATION: A 78-year-old woman was admitted to our hospital for examination of hyperbilirubinemia and liver dysfunction. Contrast-enhanced abdominal computed tomography, Magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography revealed 2 stenotic regions in the common bile duct: at its junction with the cystic duct and in the distal bile duct...

BACKGROUND: The role of adjuvant chemotherapy has not yet been established for patients with resected biliary tract cancer. S-1 has been shown to exert activity against advanced biliary tract cancer. Therefore, we evaluated the feasibility of adjuvant chemotherapy with S-1 in patients with resected biliary tract cancer. METHODS: Patients with complete macroscopic resection of intrahepatic/extrahepatic bile duct, gall bladder, or ampullary cancer were eligible. S-1 was administered orally twice daily for 4 weeks every 6 weeks, up to 4 cycles...

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...

BACKGROUND AND AIMS: ERCP-guided biliary drainage (ERCP-BD) is a criterion standard treatment for malignant biliary obstruction when curative surgery is not an option. Alternative methods such as percutaneous transhepatic biliary drainage would significantly lower the quality of life. EUS-guided biliary drainage (EUS-BD) has been developed and performed by experienced endoscopists. Therefore, the aims of this study were to evaluate the efficacy and safety of EUS-BD compared with ERCP in malignant biliary obstruction...

Confocal laser endomicroscopy (pCLE) provides real-time histologic imaging of human tissues at a depth of 60-70 μm during endoscopy. pCLE of the extrahepatic bile duct after fluorescein injection demonstrated a reticular pattern within fluorescein-filled sinuses that had no known anatomical correlate. Freezing biopsy tissue before fixation preserved the anatomy of this structure, demonstrating that it is part of the submucosa and a previously unappreciated fluid-filled interstitial space, draining to lymph nodes and supported by a complex network of thick collagen bundles...

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...

Bile acids are important cholesterol-derived nutrient signaling hormones, synthesized in the liver, that act as detergents to solubilize dietary lipids. Bile acid 7α-dehydroxylating gut bacteria generate the toxic bile acids deoxycholic acid and lithocholic acid from host bile acids. The ability of these bacteria to remove the 7-hydroxyl group is partially dependent on 7α-hydroxysteroid dehydrogenase (HSDH) activity, which reduces 7-oxo-bile acids generated by other gut bacteria. 3α-HSDH has an important enzymatic activity in the bile acid 7α-dehydroxylation pathway...

The sensitivity of bile cytology for biliary tract cancer varies from 6-64%, and hence remains unsatisfactory. Sialylated carbohydrate antigen KL-6 mucin is positive in biliary tract cancer tissues and serum KL-6 levels are significantly increased in intrahepatic ductal adenocarcinoma patients compared with healthy individuals. The aim of the present study was to evaluate the usefulness of the KL-6 concentration of bile for the diagnosis of biliary tract cancer. Bile cytology and measurements of bile KL-6 concentration were conducted for 43 patients (25 biliary tract cancers and 18 benign biliary disease)...

Bile acids or bile salts, belong to a large family of biological steroid derivatives found predominantly in the bile of mammals and other vertebrates. These amphipathic molecules possess numerous functions, including eliminating cholesterol from the body, driving the flow of bile to eliminate catabolites, emulsifying fat-soluble vitamins to enable their absorption, aiding in motility and in reducing the bacteria flora found in the small intestine and biliary tract. In this review, we investigate progress towards synthetic bile acid derivatives, with special emphasis on how they might be used for various biological applications and the challenges that remain in developing these compounds as potent drugs of the future especially in the field of microbiology (antimicrobial activities) and cancer (anticancer agents)...

The liver fluke Opisthorchis viverrini is a food-borne, zoonotic pathogen endemic to Thailand and adjacent countries in Southeast Asia. The adult developmental stage of the O. viverrini parasite excretes and secretes numerous proteins within the biliary tract including the gall bladder. Lesions caused by the feeding activities of the liver fluke represent wounds that undergo protracted cycles of healing and re-injury during chronic infection, which can last for decades. Components of the excretory/secretory (ES) complement released by the worms capably drive proliferation of bile duct epithelial cells and are implicated in establishing the oncogenic milieu that leads to bile duct cancer, cholangiocarcinoma...

Bile is a lipid-rich sterile solution produced in the liver that can be infected resulting in bactibilia. A higher incidence of postoperative infectious complications has been seen in patients with bactibilia. Recently, gram-negative bacteria have been linked to a tumor-associated inflammatory status. This study is a retrospective cohort study of 39 patients, who are over 80 years of age only (53.85% males and 46.15% females), hospitalized with diseases of the biliopancreatic system in one teaching hospital in Italy from January 2011 to December 2012 with a follow-up of 5 years...
