title: [The retrospective analysis of HBV and HCV infection in cholangiocarcinoma].
abstract: OBJECTIVE
  In order to study the diagnosis and treatment of HBV and HCV infection.
  
  
  METHODS
  We retrospectively analysed clinical data of 680 patients with cholangiocarcinoma from 1995 to 2001 and stated by SPSS software.
  
  
  RESULTS
  (1) The fastigium of cholangiocarcinoma was 60 - 65 years old. The incidence of cholangiocarcinoma was higher in aged males and the sex ratio (male:female) was 1.36:1. (2) The proximal cholangiocarcinoma was most (41.6%) and distant cholangiocarcinoma was secondly (28.7%). (3) Most patients of cholangiocarcinoma were late. The resection rate was low and the rate of radical operation was 21.6% (147/680). (4) The incidence of proximal cholangiocarcinoma was higher in the positive Serologic marks for HBV and HCV and course of diseases was short. Moreover, the pathology of. positive Serologic marks for HBV and HCV trended to low-differentiation and invasion, metastasis and the resection rate was lower.
  
  
  CONCLUSIONS
  Cholangiocarcinoma is common in the aged males. The infection of HB(C)V and hilar cholangiocarcinoma are correlated and incline to the proximal bile duct. The hilar cholangiocarcinoma infected HB(C)V may have higher malignant degree in biological characteristics and more badly prognosis.
