"Intrahepatic cholangiocarcinoma staging is conducted most commonly in accordance with the TNM staging classification of the American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC). As of 2018, the staging criteria are in their 8th edition and reflected below 1. The rare mixed hepatocholangiocarcinoma (combined hepatocellular and cholangiocarcinoma) is also staged according to the intrahepatic bile duct classification 2. However, cancers of the perihilar and distal bile ducts are staged differently."
