Current epidemiology of cholangiocarcinoma in Western countries

Cholangiocarcinomas are cancers arising from bile ducts, either found within the liver (intrahepatic) or outside the liver (extrahepatic). In Western countries, deaths due to intrahepatic cancers are rising at a higher rate than deaths due to extrahepatic cancers. This may be due to rising cases of liver disease and misclassification of the different cancer types.(c) 2022 The Author(s).

Automated summary

Cholangiocarcinomas are cancers that originate from the bile ducts and can occur within or outside the liver. In Western countries, the death rate due to intrahepatic cancers is rising at a higher rate than that of extrahepatic cancers, possibly due to an increase in cases of liver disease and misclassification of cancer types.
