T2 (tumor invades perimuscular connective tissue; no extension beyond serosa or into liver) gallbladder cancer has generally been treated by S4aS5 subsegmentectomy (S4aS5 HR). We investigated the therapeutic effect of full-thickness cholecystectomy (FC) and gallbladder bed resection (GBR), in terms of tumor location and resection margin (distance from the tumor). At our department we employ the following protocol to determine the extent of resection needed to achieve R0 status: (1) A tumor located in the gallbladder fundus (Gf) or body (Gb) and only on the free peritoneal side was classified as P-type, for which full-thickness cholecystectomy and regional lymph node dissection were performed...

The term of biliary tract cancer (BTC) refers to all tumors that arise from the biliary tract or the biliary drainage system, including the intra- and extra-hepatic bile ducts as well as the gallbladder. BTCs are aggressive tumors with limited treatment options and poor overall survival. Currently, surgery remains to be the only potentially curative treatment, and most patients develop recurrence. For advanced tumors, only limited effective treatment modalities exist today. Gemcitabine plus cisplatin is considered as a standard option for advanced biliary cancer...

Context: Gastrointestinal Stromal Tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract arising from the interstitial cells of Cajal. Succinate dehydrogenase (SDH) deficient GISTs are a unique class of GIST defined by: loss of immunohistochemical expression of SDHB indicating dysfunction of the mitochondrial complex 2, lack of driver mutations in KIT and PDGFRA, and a distinctive morphology and natural history. To date, all reported SDH-deficient GISTs have arisen in the stomach...

The Fibrolamellar variant of Hepatocellular Carcinoma (FLHCC) is a rare form of liver cancer that presents in the 3(rd) decade of life, is rarely associated with cirrhosis or chronic Hepatitis B/C virus infection, and usually presents with normal serum alpha-fetoprotein (AFP) levels. FLHCC presenting during pregnancy is extremely rare, with only 4 cases reported. We present a case of FLHCC in pregnancy and discuss the dilemmas in management. A 26 year-old primigravida, 26 weeks of gestation presented with a month's history of obstructive jaundice secondary...

PURPOSE: High intensity focused ultrasound (HIFU) is a non-invasive therapeutic technique that can thermally ablate tumors. Boiling histotripsy (BH) is a HIFU approach that can emulsify tissue in a few milliseconds. Lesion volume and temperature effects for different BH sonication parameters are currently not well characterized. In this work, lesion volume, temperature distribution, and area of lethal thermal dose were characterized for varying BH sonication parameters in tissue-mimicking phantoms (TMP) and demonstrated in ex vivo tissues...

Cholangiocarcinoma (CCA) is an aggressive malignancy of the bile ducts, with poor prognosis and limited treatment options. Here, we describe the integrated analysis of somatic mutations, RNA expression, copy number, and DNA methylation by The Cancer Genome Atlas of a set of predominantly intrahepatic CCA cases and propose a molecular classification scheme. We identified an IDH mutant-enriched subtype with distinct molecular features including low expression of chromatin modifiers, elevated expression of mitochondrial genes, and increased mitochondrial DNA copy number...

BACKGROUND Adenocarcinoma of the colon frequently invades adjacent organs, spreads intraperitoneal, and metastasizes to intestinal lymph nodes, lungs, and the liver. Metastasis solely to the extrahepatic bile duct is extremely rare and has only been previously reported on 15 occasions. The accurate determination that an extrahepatic common bile duct lesion is of colonic origin has critical therapeutic implications. CASE REPORT The patient was a 50-year-old male with a history of colon cancer S/P surgical resection in September 2014...

Fascioliasis is a rarely encountered parasitic infection in Turkey that mainly affects the liver and bile ducts. Other defined localizations of the parasite are the lungs, gastrointestinal system, and subcutaneous fatty tissue. Two cases of female patients who presented to the hospital with abdominal pain and whose physical examination and laboratory findings were normal except peripheral eosinophilia, were detected to have liver masses with necrotic areas. Segmental hepatectomies were performed in both cases with the preliminary diagnosis of liver tumors...

Intrahepatic cholangiocarcinoma (iCC) is a primary carcinoma of the liver with increasing significance and major pathogenic, clinical and therapeutic challenges. Classically, it arises from malignant transformation of cholangiocytes bordering small portal bile duct (BD) to second-order segmental large BDs. It has three major macroscopic growth pattern [mass-forming (MF), periductal infiltrative (PI), and intraductal growth (IG)] and histologically is a desmoplastic stroma-rich adenocarcinoma with cholangiocyte differentiation...

Intrahepatic cholangiocarcinoma (ICC) is the second most common malignancy arising from the liver. ICC makes up about 10% of all cholangiocarcinomas. It arises from the peripheral bile ducts within the liver parenchyma, proximal to the secondary biliary radicals. Histologically, the majority of ICCs are adenocarcinomas. Only a minority of patients (15%) present with resectable disease, with a median survival of less than 3 years. Multidisciplinary management of ICC is complicated by large differences in disease course for individual patients both across and within tumor stages...

Background: Intraductal papillary neoplasm of the bile duct (IPNB) is a specific entity for which there has been no classification that correlates clinical presentation with patient survival. We, therefore, propose a new classification based on radio-pathological appearance correlated with clinical findings including outcome. Methods: We retrospectively reviewed the medical and pathological records of 103 IPNB patients who underwent curative-intent hepatic resection between January 2008 and December 2011. A morphological classification was then created based on the presence of (a) bile duct dilatation, (b) intraductal mass(es), (c) cystic lesion(s), and (d) macro-invasion of the liver...
