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...

Neuroendocrine tumors (NETs) of the extrahepatic bile duct are extremely rare and reported infrequently in the literature. These tumors are difficult to diagnose preoperatively, and the prognosis is variable, often determined by extent of disease, tumor grade and resectability. This case report presents a 45-year-old male with history of biliary obstruction relieved by endobiliary stents with common hepatic duct stricture just above the cystic duct, thought to be a Klatskin's cholangiocarcinoma. Final pathological examination was consistent with primary extrahepatic NET...

The Hippo signaling pathway and the Notch signaling pathway are evolutionary conserved signaling cascades that have important roles in embryonic development of many organs. In murine liver, disruption of either pathway impairs intrahepatic bile duct development. Recent studies suggested that the Notch signaling receptor Notch2 is a direct transcriptional target of the Hippo signaling pathway effector YAP, and the Notch signaling is a major mediator of the Hippo signaling in maintaining biliary cell characteristics in adult mice...

Cholangiocarcinoma (CCA) is a highly malignant bile duct cancer that tends to invade and metastasize early. The epithelial-mesenchymal transition (EMT) has been implicated in cancer cell invasion and metastasis, as well as in cancer cell evasion of host immunity. In this study, we investigated the interaction between atypical protein kinase C-iota (aPKC-ι) and Snail in the regulation of EMT and its relationship to CCA immunosuppression. Our results demonstrated that aPKC-ι, Snail, and infiltrated immunosuppressive cells were significantly up-regulated in CCA tumor tissues and were linked to poor prognosis...

OBJECTIVE: Intrahepatic cholangiocarcinoma (ICC) is a malignant tumor that arises from the intrahepatic bile ducts. Although the pathologic and imaging features of ICC have been clearly identified, recent updates have addressed the pathologic classification and imaging features of ICC using new imaging techniques. First, a proposed new pathologic ICC subclassification includes perihilar large duct and peripheral small duct ICCs. Second, advanced MR-based imaging features of ICC, such as hepatobiliary phase imaging using hepatocytespecific contrast material and DWI, have recently been described...

Remarkable advancements in techniques of genomic profiling and bioinformatics have led to the accumulation of vast amounts of knowledge on the genomic profiles of biliary tract cancer (BTC). Recent largescale molecular profiling studies have not only highlighted genomic differences characterizing tumors of the intrahepatic and extrahepatic bile ducts and gallbladder, but have also revealed differences in genomic profiles pertaining to associated risk factors. Novel genomic alterations such as FGFR2 fusions and IDH1/2 mutations in intrahepatic cholangiocarcinoma (ICC) and ERBB2 alterations in gallbladder cancer (GBCA) are emerging as targeted therapy options capable of advancing precision medicine for the care of these patients...

CLINICAL RELEVANCE: Cholangiocarcinoma is a cancer of bile duct cells for which no effective biomarker exists. Tumor masses are often not identifiable by imaging modalities as a result of the location of the tumor in the hilum of the liver or within the bile ducts. Because of the problems with obtaining a definitive tissue diagnosis, treatment and management decisions for patients with biliary strictures that may be malignant are difficult. The work presented here highlights the potential role of fucosylated fetuin-A as a biomarker of cholangiocarcinoma and may help in the early detection of this deadly cancer...

Extension of ampulloma into the lower common bile duct (CBD) is observed in up to 30% of cases. This biliary extension can prevent complete tumor resection thus is considered as a contraindication for endoscopic and even surgical ampullectomy. For ampullomas associated with a prolonged biliary extension, a pancreaticoduodenectomy is associated with a high morbidity and can be considered as an overtreatment for a benign neoplasm. The present study describes a new surgical approach including ampullectomy with complete resection of the intrapancreatic CBD and restoration of both biliary and pancreatic flow by two separate anastomoses...

Intraductal papillary epithelial neoplasms of the pancreatobiliary system (intraductal papillary neoplasm of the bile duct (IPNB) and intraductal papillary mucinous neoplasm (IPMN)) seem to share many clinicopathological features; however, IPNB has not been fully characterized. In order to understand the clinicopathological/immunohistochemical features of IPNB better, we compared 52 cases of IPNB with 42 cases of IPMNs with mural nodules. The IPNB cases were divided into two groups according to their histological similarity and according to five key histological findings...

Cholangiocarcinoma is an epithelial malignancy arising in the region between the intrahepatic bile ducts and the ampulla of Vater at the distal end of the common bile duct. The effect of current chemotherapy regimens against cholangiocarcinoma is limited, and the prognosis of patients with cholangiocarcinoma is poor. Aberrant DNA methylation and histone modification induce silencing of tumor suppressor genes and chromosomal instability during carcinogenesis. Studies have shown that the tumor suppressor genes and microRNAs (miRNAs) including MLH1, p14, p16, death-associated protein kinase (DAPK), miR-370 and miR-376c are frequently methylated in cholangiocarcinoma...
