Stages of Extrahepatic Bile Duct Cancer
In stage III, cancer has spread:
- to the main portal vein or to both right and left branches of the portal vein; or
- to the hepatic artery; or
- to other nearby organs or tissues, such as the colon, stomach, small intestine, or abdominal wall.
Cancer may have spread to nearby lymph nodes also.
In stage IV, cancer has spread to lymph nodes and/or organs far away from the extrahepatic bile duct.
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
Unresectablecancer 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 abdominalcavity, or to distant parts of the body.
