Carcinoma of the Extrahepatic Bile Ducts
Compared to carcinomas of the gallbladder, carcinomas of the extrahepatic bile ducts are less common, occur more often in men than in women, are usually not associated with lithiasis, and have a different epidemiologic distribution [1–3, 7, 12]. The prognosis for extrahepatic bile duct carcinomas is very poor, with an overall 5-year survival rate of only about 12%. Herein we describe the results of our analysis of the prognostic factors for carcinomas of the extrahepatic bile ducts. This analysis is based primarily on published reports on the prognostic factors in cancers of the extrahepatic bile ducts, including data from the Surveillance, Epidemiology, and End Results (SEER) Program of the National Cancer Institute. No multivariate analysis has been reported on combinations of the different prognostic factors.
