PURPOSE: Patients with Lynch syndrome (LS) have a significantly elevated lifetime risk of developing biliary tract cancers (BTCs) compared to the general population. However, few studies have characterized the clinical characteristics, genetic features, or long-term outcomes of mismatch-repair deficient (dMMR) cholangiocarcinomas associated with LS. METHODS: A retrospective review of a prospectively maintained Familial High-Risk GI Cancer Clinic database identified all patients with BTCs evaluated from 2006 to 2016 who carried germline mutations in MLH1, MSH2, MSH6, or PMS2...

BACKGROUND: Gallbladder cancer is the most common malignant cancer of the bile ducts and third most common gastrointestinal malignant in the world for public health. Its relatively low incidence and confused symptoms result in advanced disease at the time of presentation, contributing to poor prognosis and reduced survival associated with this disease. The main function of the gallbladder is to store excreted bile acids from the liver in preparation for a meal. Its main risk factor is prolonged exposure to biliary calculations, although bacterial infections and other inflammatory conditions are associated...

Mesenteric masses are infrequent lesions ranging from benign cysts to aggressive malignancies and often present a diagnostic and therapeutic challenge. The mesentery is a frequent recipient of metastases from the gastrointestinal tract, pancreas, and biliary cancers. Primary mesenteric tumors are relatively rare, mostly mesenchymal in origin and benign in nature. Examples include gastrointestinal stromal tumors and smooth muscle tumors. We describe a 50-year-old woman, who presented with a lump in the left hypochondrium along with altered bowel habits of 2 years' duration...

AIMS: Advanced biliary tract carcinomas (ABC) are malignancies with limited effective therapies for advanced disease. There is little published evidence of outcomes of ABC patients participating in phase I clinical trials. MATERIALS AND METHODS: Patient characteristics, treatment details and outcomes of ABC patients treated at a dedicated phase I unit were captured and analysed from case and trial records. RESULTS: In total, 123 ABC patients were included in the study, of which 48 patients participated in 41 different phase I trials; 75 (61%) did not participate due to rapid disease progression or patient choice...

BACKGROUND/PURPOSE: The use of PBD for managing patients with periampullary cancer awaiting surgery remains controversial. The impact of PBD status and type on surgical outcomes has not been established, leading to a lack of consensus. We aimed to evaluate the impact of preoperative biliary drainage (PBD) on short-term surgical outcomes in curatively resected periampullary cancer. METHODS: We retrospectively reviewed data from patients undergoing curative periampullary cancer resection...

BACKGROUND: Portal vein embolization is essential for patients with biliary cancer who undergo extended hepatectomy to induce hypertrophy of the future remnant liver. Over 830 patients have undergone the portal vein embolization at our institution since 1990. Non-alcoholic fatty liver disease is an entity of hepatic disease characterized by fat deposition in hepatocytes. It has a higher prevalence among persons with morbid obesity, type 2 diabetes, and hyperlipidemia. Neither the mechanism of hepatic hypertrophy after portal vein embolization nor the pathophysiology of non-alcoholic fatty liver disease has been fully elucidated...

Introduction: CA 19-9 is used as a tumor marker in colon, pancreas, biliary, and gastric cancers. Laryngeal cancer is the most common malignant epithelial tumor among head and neck cancers and has no specific tumor marker. Case report: A 66-year-old male patient had severe reflux symptoms during 5 years and had an isolated CA 19-9 elevation. Follow-up analysis revealed that he had larynx cancer and after laryngectomy, CA 19-9 levels decreased to normal range. Discussion: Currently, CA 19-9 is not a marker for malignancy...

OBJECTIVE: Biliary forceps biopsies are essential for differentially diagnosing biliary strictures and evaluating the preoperative superficial intraductal spread of bile duct cancers; however, these biopsies are technically demanding and time consuming. Using controllable biopsy-forceps (C-BF), which enable the tip's angle to be adjusted by up to 90°, may facilitate the procedure and improve the diagnostic yield for biliary biopsies. This study aimed to examine the efficacy of C-BF associated with the diagnosis of biliary strictures...

Overexpression of the oncofetal insulin-like growth factor 2 mRNA-binding protein 2 (IMP2/IGF2BP2) has been described in different cancer types. Gallbladder carcinoma (GBC) is a rare but highly aggressive cancer entity with late clinical detection and poor prognosis. The aim of this study was to investigate the role of IMP2 in human GBC. Tissue microarrays (TMAs) of an international multi-center GBC sample collection from n = 483 patients were analyzed by immunohistochemistry. IMP2 immunoreactivity was found in 74...

Although intrabiliary metastasis of carcinoma in the liver is unusual, intraductal and/or intraepithelial spread of cancer cells along intrahepatic bile ducts is now well recognized as hepatic metastasis. However, several clinical and laboratory findings, including images, lead us to differentially diagnose from primary intrahepatic cholangiocarcinoma. We report here on a case of colonic adenocarcinoma that metastasized to the liver with spread along with the intrahepatic bile duct of S5/6 area. The patient was a 51-year-old man and clinically diagnosed liver metastasis of sigmoid colon cancer (tub2, pMP, ly1, v0, n0), which was diagnosed and treated by sigmoidectomy 7 years ago...

BACKGROUND: Recommended treatments of patients with advanced biliary tract cancer (aBTC) are limited to one chemotherapy doublet. Nevertheless, efficacy of treatment personalisation for aBTCs is supported by accumulating evidences but remains to be evaluated. PATIENTS AND METHODS: Patients with aBTCs included in the prospective clinical trial MOSCATO-01 were treated by at least one previous systemic treatment, had an ECOG performance status of 0-1, and at least one tumour site accessible to biopsy...

Background: Kras mutations and increased Notch activation occur frequently in gallbladder cancer. However, their roles in gallbladder carcinogenesis have not been defined. This study was aimed at determining whether expression of mutant Kras was sufficient to induce gallbladder carcinoma and whether Notch deregulation played a role in this context. Methods: We determined Cre recombination activity of Pdx1-Cre in the gallbladder using a reporter strain and examined gallbladder tumor development in the Kras(LSL- G12D/+);Pdx1-Cre mice...
