Definition

Stage III intrahepatic bile duct cancer is divided into stages IIIA and IIIB. In stage IIIA, the tumor has spread through the capsule (outer lining) of the liver. In stage IIIB, cancer has spread to organs or tissues near the liver, such as the duodenum, colon, stomach, common bile duct, abdominal wall, diaphragm, or the part of the vena cava behind the liver, or the cancer has spread to nearby lymph nodes.
