Extrahepatic Bile Duct Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Extrahepatic Bile Duct Cancer
In stage IV, cancer has spread to other parts of the body, such as the liver or lungs.
Extrahepatic bile duct cancer can also be grouped according to how the cancer may be treated. There are two treatment groups:
Localized (and resectable)
The cancer is in an area where it can be removed completely by surgery.
Unresectable, recurrent, or metastatic
Unresectable cancer cannot be removed completely by surgery. Most patients with extrahepatic bile duct cancer have unresectable cancer.
Recurrent cancer is cancer that has recurred (come back) after it has been treated. Extrahepatic bile duct cancer may come back in the bile duct or in other parts of the body.
Metastasis is the spread of cancer from the primary site (place where it started) to other places in the body. Metastatic extrahepatic bile duct cancer may have spread to nearby blood vessels, the liver, the common bile duct, nearby lymph nodes, other parts of the abdominal cavity, or to distant parts of the body.
