肝炎病毒感染与肝门部胆管癌发病关系的探讨

目的　探讨乙型肝炎 (乙肝 )和丙型肝炎 (丙肝 )病毒感染在肝门部胆管癌发病中的作用。　方法　采用免疫组织化学方法对 6 8例石蜡包埋肝门部胆管癌患者手术标本中乙肝病毒X蛋白和丙肝病毒C蛋白水平进行检测 ,并结合临床资料进行分析。　结果　 6 8例肝门部胆管癌中乙肝病毒X蛋白阳性率为 8 8% (6 / 6 8) ,丙肝病毒C蛋白阳性率为 35 3% (2 4 / 6 8) ,两者均阳性 1例(1 5 % ) ;乙肝、丙肝病毒感染的肝门部胆管癌在分化程度 (χ2 =8 7,P <0 0 1)、浸润程度 (χ2 =6 7 8,P<0 0 1)、淋巴结转移 (χ2 =4 3,P <0 0 5 )、根治程度 (χ2 =5 1,P <0 0 5 )与非病毒感染的肝门部胆管癌比较差异有显著意义。　结论　乙肝病毒X蛋白、丙肝病毒C蛋白可能在乙肝、丙肝病毒感染肝门部胆管癌的发病原因中起重要作用。乙肝、丙肝病毒感染的肝门部胆管癌恶性程度高 ,可能预后较差

Pathogenesis of hilar cholangiocarcinoma and infection of hepatitis virus

Objective To study the correlation between hepatic hilar cholangiocarcinoma and the infection of HB(C)V. Methods Combined with clinical data, immunohistochemistry was used to detect HBXAg antigen and HCV C protein in 68 formalin fixed and paraffin embedded samples of hilar cholangiocarcinoma. Results Six cases(8 8%) were positive to HBXAg antigen and 24 cases (35 0%) to HCV C protein respectively. One case was positive to both HBXAg antigen and HCV C protein. There were statistical differences in differentiation and invasion, lymph node metastasis, treatment between hilar cholangiocarcinomas infected HB(C)V and those non infected. Conclusions HBXAg antigen and HCV C protein may play an important role in the pathogenesis of hilar cholangiocarcinoma. Hilar cholangiocarcinoma infected HB(C)V may have a high malignancy and more poor prognosis.
