Overview
Classification
Cholangiocarcinoma may be classified according to location of the tumor into three subtypes:[1]
- Extrahepatic bile duct cancer
- Perihilar bile duct cancer
- Intrahepatic bile duct cancer
Cellular Classification of Cholangiocarcinoma
Extrahepatic Bile Duct Cancer
- Carcinoma in situ
- Adenocarcinoma, not otherwise specified (NOS)
- Adenocarcinoma
- Intestinal type
- Mucinous type
- Clear cell type
- Signet-ring cell carcinoma
- Adenosquamous carcinoma
- Squamous cell carcinoma
- Small cell (oat cell) carcinoma
- Undifferentiated carcinoma
- Spindle cell type
- Giant cell type
- Small cell type
- Papillomatosis
- Papillary carcinoma
- Noninvasive
- Papillary carcinoma
- Invasive
- Carcinoma, NOS
Perihilar Bile Duct Cancer The histologic types include the following:
- Carcinoma in situ
- Adenocarcinoma, not otherwise specified (NOS)
- Adenocarcinoma:*Intestinal type
- Mucinous type
- Clear cell type
- Signet-ring cell carcinoma
- Adenosquamous carcinoma
- Squamous cell carcinoma
- Small cell (oat cell) carcinoma
- Undifferentiated carcinoma
- Spindle cell type:*Giant cell type
- Small cell type
- Papillomatosis
- Papillary carcinoma:*Noninvasive
- Papillary carcinoma*:Invasive
- Carcinoma, NOS
Intrahepatic Bile Duct Cancer
- Mass-forming tumor growth pattern
- Periductal-infiltrating tumor growth pattern
- Mixed mass-forming and periductal-infiltrating growth pattern
Bismuth-Corlette classification
The Bismuth-Corlette classification is a classification system for perihilar cholangiocarcinomas, which is based on the extent of ductal infiltration:
Type I Limited to the common hepatic duct, below the level of the confluence of the right and left hepatic ducts
Type II Involves the confluence of the right and left hepatic ducts
Type IIIa Type II and extends to the bifurcation of the right hepatic duct
Type IIIb Type II and extends to the bifurcation of the left hepatic duct
Type IV Extending to the bifurcations of both right and left hepatic duct or multifocal involvement
Type V Stricture at the junction of common bile duct and cystic duct
The classification system may be used both for cholangiocarcinoma and benign strictures ref required.
