The role of sex in the outcomes of patients with biliary tract cancers remains unclear: A population-based study - 06/12/18
Abstract |
Background |
Differences in outcomes between males and females with biliary tract cancer (BTC) has been previously reported but not studied.
Methods |
This was a population-based retrospective cohort study of patients undergoing BTC resection in Ontario between 2002 and 2012. Descriptive statistics on patient, disease, and treatment-related factors in each BTC subtype were reported. Kaplan Meier Curves and Cox Proportional Hazards analysis were used to examine the univariate relationship between sex and overall survival.
Results |
714 patients underwent resection of a BTC. Kaplan Meier Curves shows trends towards different survival for males and females in different BTC subtypes: improved for females with intrahepatic and ampullary cancers and poorer survival for females with perhilar and distal cholangiocarcinomas. These trends were not statistically significant.
Conclusions |
Sex may be an important factor in overall survival following resection of BTC. Further work is needed to better characterize the relationship between sex and outcomes of BTC.

• | Biliary tract cancer (BTC) subtypes represent individual disease processes and should be studied separately. |
• | This study describes sex-related survival differences between BTC subtypes. These trends, however, did not reach statistical significance. |
• | Collaborative work is required to establish larger cohorts to characterize the relationship between sex and outcomes in BTC. |
