Overview
Cholangiocarcinoma may be classified according to location of the tumor into three subtypes: extrahepatic bile duct cancer, perihilar bile duct cancer, and intrahepatic bile duct cancer.[1] Perihilar cholangiocarcinoma may be classified according to Bismuth-Corlette classification into five subtypes based on the extent of ductal infiltration.
Classification
Cholangiocarcinoma may be classified according to location of the tumor into three subtypes:[2]
- 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
- 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
- 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
Perihilar cholangiocarcinoma may be classified according to Bismuth-Corlette classification into five subtypes based on the extent of ductal infiltration:[3]
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
