Hepatobiliary cancers are common worldwide and highly lethal. Hepatocellular carcinoma is the most common hepatobiliary malignancy and the seventh most common cancer worldwide. Gallbladder cancer is the most common biliary tract malignancy, accounting for approximately 5000 newly diagnosed cases in the United States. Cholangiocarcinomas are diagnosed throughout the biliary tree and are usually classified as intrahepatic or extrahepatic. Intrahepatic cholangiocarcinomas arise from intrahepatic small-duct radicals, whereas extrahepatic cholangiocarcinomas encompass hilar carcinomas (including Klatskin's tumors). These guidelines discuss these subtypes of hepatobiliary cancer and the epidemiology, pathology, etiology, staging, diagnosis, and treatment of each subtype.
