title: [Comparison of clinicopathological characteristics and prognosis of intrahepatic biliary cystic tumor between male and female patients].
abstract: OBJECTIVE
  To describe the clinicopathological characteristics and prognosis of intrahepatic biliary cystic tumor (IBCT) and compare the difference betwwen male and female patients.
  
  
  METHODS
  11 male and 45 female patients with histological confirmed IBCT from January 2003 to April 2014 were envolved. clinical characteristics, laboratory examination, radiological features, treatment method and prognosis were analyzed.
  
  
  RESULTS
  The mean age of male patients with IBCT was significantly older than that of female patients (54.9±10.1 years vs 46.2±12.9 years, P=0.041). There were no significant differences in radiological features between male and female patients except for mural nodules (10/11 vs 15/45, P=0.001). Intrahepatic biliary cystadenocarcinoma (IBC) was more common in male patients than female patients (8/11 vs 16/45, P=0.041). Male patients had worse prognosis than female patients (P=0.014). 1-year, 3-year, and 5-year survival of male patients was 90.9%,45.5%,30.3%, respectively. However, 1-year, 3-year, and 5-year survival of female patients was 94.8%,82.7%,78.6%.
  
  
  CONCLUSIONS
  Male patients had low incidence of IBCT, and were more common for IBC. Even with complete resection, the long-term survival was still poor, close follow-up were recommended especially for male patients.
