Abstract Biliary tract cancers are uncommon malignancies arising from biliary epithelium intrahepatically (peripheral cholangio- carcinoma), in the extrahepatic bile duct, the gall bladder and the ampulla of Vater. Treatment has been challenging because of late presentation, complex surgery, complex biliary obstruction with jaundice and a paucity of high quality data on which to establish standard care. With improvements in imaging, biliary stenting, surgical management and the establishment of a national investigational programme we hope to define the modern management of biliary tract cancers and enable a platform for further research.

Key Words: biliary tract cancer, surgery, , , clinical trials

Introduction factors fall primarily into two groups: genetic and inflammatory (Table I). Biliary tract malignancy comprises adenocarcinomas The incidence of BTC in the western world is of biliary epithelium. These are geographically dis- primarily related to gallstones and primary sclerosing tinct, arising from biliary epithelium within hepatic cholangitis (PSC), whereas that in the Far East is substance, known as peripheral cholangiocarcinomas, related to infective causes.

Perito- neal and distant metastasis increases to 50% with serosal involvement of the gall bladder, thus careful preoperative evaluation of the extent of gall bladder involvement is critical. Those tumours limited to the mucosa of the gall bladder (T12 tumours) should be treated with cholecystectomy. Any more advanced tumours should be treated with aggressive lymphatic and nodule resection, although there are few rando- mized data to suggest this improves survival. There are only two major surgical series of GBC (Table VI). There is a single adjuvant study reporting an improvement in survival for GBC patients receiving Figure 5.
