Core Tip
Core tip: Hepatobiliary cancers are highly lethal cancers which are difficult to diagnose early and for which few therapeutic options are available. Its etiological factors have been suggested to include chronic inflammation, obstruction of the bile ducts, and impaired bile flow, as well as infection with Helicobacter species, such as Helicobacter bilis and Helicobacter hepaticus, in a manner that is similar to the reported role of Helicobacter pylori in distal gastric cancer. Population genetics, geographical and environmental factors, cholelithiasis, obesity, parity, and endemic infection with liver flukes have been identified as risk factors that influence the development of biliary tract tumors.
