Sex disparity in clinical characteristics and long-term prognosis after liver resection for patients with intrahepatic cholangiocarcinoma: A propensity score matching analysis.

Aim: To compare the survival outcomes between male and female patients with intrahepatic cholangiocarcinoma who underwent liver resection.

Methods: Data from 976 consecutive intrahepatic cholangiocarcinoma patients undergoing liver resection between January 2005 and May 2013 at the Eastern Hepatobiliary Surgery Hospital were prospectively collected and retrospectively reviewed. Patient clinicopathological characteristics, overall survival, and cumulative recurrence rates were compared between male and female patients using propensity score matching.
