Methods: Immunohistochemistry was used to detect HCV antigen and HBxAg. Results: HCV C33c antigen was present in the cytoplasm of cancer cells and hepatic cells and HCV core antigen was present mainly in the nuclei of cancerous tissues and in the cytoplasm of pericancerous liver tissues. In cancerous tissues and pericancerous tissues the positive rates of HCV C33c antigen were 60% (21/35) and 100% (21/21 ) respectively; the positive rates of HCV core antigen were 87. 8% (29/ 33 ) and 61. 9% (13/21) respectively; the positive rates of HBxAg were 74. 3% (26/35) and 76. 2% (16/21) respectively; the simultaneously positive rates of C33c and HBxAg were 48. 6% (17/35) and 76. 2% (16/21). Conclusion: Besides hepatitis B virus (HBV) infection, HCV infection may play an important role in the carcinogenesis of PIC.展开更多
