Cholangiocarcinoma (staging)

Cholangiocarcinoma staging is most commonly classified using the TNM staging systems of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC), which starting January 1, 2018 is according to its 8 edition. There are separate systems depending on whether the cholangiocarcinoma arises primarily from intrahepatic, perihilar/hilar (Klatskin), or extrahepatic (distal) bile ducts . These are detailed separately:

• intrahepatic cholangiocarcinoma (staging)
• perihilar cholangiocarcinoma (staging)
• distal cholangiocarcinoma (staging)

• Bismuth-Corlette classification of perihilar cholangiocarcinoma
