Background and study aims Biliary stenting of unresectable malignant bile duct obstruction is generally accepted as the standard of care but it can be hampered by tumor ingrowth and stent dysfunction. We aimed to test the feasibility, safety, and biliary patency rate of a new endoscopically applied intraductal radiofrequency ablation (RFA) device. Patients and methods Eighteen patients with inoperable malignant biliary obstruction underwent endoscopic retrograde cholangiopancreatography (ERCP)-directed RFA and stenting...

Surgery is the mainstay curative treatment in most cancer. We aimed to test the new hypothesis that cancer surgery performed during holiday periods is associated with worse long-term prognosis than for non-holiday periods. This nationwide Swedish population-based cohort study included 228,927 patients during 1997-2014 who underwent elective resectional surgery for a cancer where the annual number of resections was over 100. The 16 eligible cancer sites were grouped into 10 cancer groups. The exposure, holiday periods, was classified as wide (14-weeks) or narrow (7-weeks)...

Primary neuroendocrine tumors of the extrahepatic bile ducts are extremely rare - up to date, only 77 cases have been reported in the literature, which represents between 0.2-2% of all gastrointestinal carcinoid tumors. The paper focuses on the case of a woman patient, aged 37 years, admitted to the Clinic with the diagnosis of obstructive jaundice, unaccompanied by pain and where imaging indicates a tumor in the third average of the common bile duct (CBD). The surgery involved the excision of CBD, lymphadenectomy and restoring the biliodigestive continuity of Roux-en-Y hepaticojejunostomy...

Diphenylarsinic acid (DPAA), a neurotoxic organic arsenical used as a chemical warfare agent, is present in the groundwater and soil in some regions of Japan due to illegal dumping after World War II. We previously demonstrated that DPAA promotes diethylnitrosamine-induced liver carcinogenesis in a medium-term rat liver bioassay. The purpose of the present study was to evaluate the potential carcinogenicity of DPAA, including investigation of whether the bile duct hyperplasia in the liver that was observed in a previous 52 week rat chronic study develops into a tumor, when administered to rats in their drinking water for 104 weeks...

Biliary tract cancer (BTC) is one of the most devastating types of malignant neoplasms worldwide. However, the mechanisms underlying the development and progression of BTC remain unresolved. BTC includes extrahepatic bile duct carcinoma (EBDC), gallbladder carcinoma (GBC) and ampulla of Vater carcinoma (AVC), named according to the location of the tumor. Although genetic alterations of intrahepatic cholangiocarcinoma have been investigated, those of EBDC, GBC and AVC have not yet been fully understood. The present study analyzed somatic mutations of 50 cancer-associated genes in 27 Japanese BTC cells, including: 11 EBDC, 14 GBC and 2 AVC...

INTRODUCTION: The use of adjuvant treatment (AT) in resected biliary tract cancers (BTC) is still controversial. No efficacy comparison has been performed between chemotherapy (CT) and chemoradiotherapy (CTRT). A systematic review of the available evidence regarding adjuvant chemotherapy (AC) in resected BTC was performed. METHODS: PubMed, EMBASE, Web of Science, SCOPUS and The Cochrane Library databases were searched for relevant articles published. Only studies including at least 50 patients affected by tumors of gallbladder, intrahepatic, perihilar, and distal bile ducts were considered...

REVIEW

The ErbB/HER family comprises four distinct tyrosine kinase receptors, EGFR/ErbB1/HER1, ErbB2/HER2, ErbB3/HER3 and ErbB4/HER4, which trigger intracellular signals at the origin of essential cellular functions including differentiation, proliferation, survival and migration. Epithelial cells, named cholangiocytes, that line intrahepatic and extrahepatic bile ducts, contribute substantially to biliary secretory functions and bile transport. Although ErbB receptors have been widely studied in cholangiocarcinoma (CCA), a malignancy of the biliary tract, knowledge of these receptors in biliary epithelium physiology and in non-malignant cholangiopathies is far from completed...

Labile iron pool is a cellular source of ions available for Fenton reactions resulting in oxidative stress. Living organisms avoid an excess of free irons by a tight control of iron homeostasis. We investigated the altered expression of iron regulatory proteins and iron discrimination in the development of liver fluke-associated cholangiocarcinoma. Additionally, the levels of labile iron pool and the functions of transferrin receptor-1 on cholangiocarcinoma development were also identified. Iron deposition was determined using the Prussian blue staining method in human cholangiocarcinoma tissues...

A 63-year male was admitted with abdominal pain, fever and jaundice. The contrast-enhanced computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiography showed a mass in the hepatic hilar region with dilation of the intrahepatic bile duct. The left branch of portal vein was also compressed by the mass. The patient was diagnosed as intrahepatic bile duct carcinoma and underwent the left hemihepatectomy together with right hepatic duct jejunum anastomosis (Roux-en-Y)combined with hepatoduodenal ligament lymphadenectomy...

BACKGROUND: The Hippo pathway plays a vital role in liver regeneration and development by determining cellular lineage and regulating cell proliferation and apoptosis. In this study, we aimed to assess the role of the Hippo pathway in hepatic carcinogenesis and morphogenesis by examining Yes-associated protein 1 (YAP1) expression in the spectrum of hepatic carcinomas based on cellular lineage. METHODS: We examined 913 primary hepatic carcinomas, including hepatocellular carcinomas (HCCs), combined hepatocellular and cholangiocarcinomas (cHC-CCAs), intrahepatic cholangiocarcinomas (IHCCAs) and perihilar extrahepatic bile duct carcinomas (EHBCAs)...

The aim of this study was to investigate the relationship between the clinicopathological characteristics of intrahepatic cholangiocarcinoma (ICC) and both disease-free survival (DFS) and overall survival (OS) in intrahepatic cholangiocarcinoma (ICC) patients who underwent radical resection (R0). We retrospectively analyzed the clinicopathological characteristics of 319 patients who underwent radical resection of ICC between October 1999 and December 2003. The independent adverse prognostic factors that affected DFS after radical resection of ICC were as follows: maximum tumor diameter (HR = 1...

BACKGROUND: Rupture of the common bile duct is a life-threatening condition, usually observed after a trauma or in association with choledocholithiasis or an obstructive tumor of the bile duct. However, a spontaneous rupture of the common bile duct is a rare entity. CASE PRESENTATION: We report a new observation of a spontaneous rupture of the common bile duct, associated with biliary peritonitis and pancreatitis, in a 15-year-old North African girl. Etiological aspects, specificities of clinical presentation, means of diagnosis, as well as surgical and perioperative management are discussed...

Pancreaticobiliary maljunction (PBM) is a congenital malformation that is associated with biliary cancer development. When patients are diagnosed with PBM, a diversion operation is recommended. Although a risk remains for developing residual bile duct carcinoma following diversion, the development of a carcinoma of the ampulla of Vater after a diversion operation for PBM is rare. We present a treated case of carcinoma of the ampulla of Vater after a diversion operation for PBM. A 65-year-old woman presented with abdominal pain...

Cholangiocarcinoma is a primary malignant tumor of the bile duct epithelium. Cholangiocarcinoma is usually detected at an advanced stage when successful treatment is no longer possible. As the tumor originates from the bile duct epithelium, bile is an ideal source of tumor biomarkers for cholangiocarcinoma. In this study, we used a quantitative proteomics approach to identify potential tumor-associated proteins in the bile fluid of six cholangiocarcinoma patients. Three different gross-appearance tumor types were used in the analysis: mass-forming type ( n = 2), periductal infiltrating type ( n = 2), and intraductal growth type ( n = 2)...

BACKGROUND AND AIMS: Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with unclear etiology that may show functioning or non-functioning features. Primary tumor localization often requires integrated imaging. The European Neuroendocrine Tumors Society (ENETS) guidelines proposed wireless-capsule endoscopy (WCE) as a possible diagnostic tool for NETs, if intestinal origin is suspected. However, its impact on therapeutic management is debated. We aimed to evaluate the yield of WCE in detecting intestinal primary tumors in patients showing liver NET metastases when first-line investigations are inconclusive...

INTRODUCTION: Intraductal papillary neoplasms of the bile duct have been recognized as a differentiated entity to other biliary tumors since 2001. They are characterized by intraductal growth, with or without mucus production, and have malignant potential, although they have a better prognosis than other types of cholangiocarcinoma. MATERIAL AND METHODS: From January 2010 to August 2015, we included three patients with a confirmed diagnosis of bile duct intraductal papillary neoplasia with malignancy that were treated at our center...
