Stage III is divided into stages IIIA and IIIB. In stage IIIA, the tumor has spread to one branch of the hepatic artery or of the portal vein. In stage IIIB, the tumor has spread to nearby lymph nodes. Cancer has also spread into the wall of the perihilar extrahepatic bile duct (where the bile duct leaves the liver) and may have spread through the wall to nearby fatty tissue, the liver, or to one branch of the hepatic artery or of the portal vein.
