Study of the relationship between HAI and HBsAg,HCV expression in HCC,pericarcinomatous tissues with immunohistochemistry / 中华传染病杂志

ABSTRACT

Objective To study the relationship between HAI and HBsAg, HCV in HCC, pericarcinomatous tissues. Methods The patterns of HBsAg and HCV in 100 cases of hepatocellular carcinoma(HCC) and their surrounding liver tissues were studied on paraffin-embeded sections with immunohistochemistry technique, and pericarcinomatous tissues were scored in Knodell’s histological activity index(HAI). Results The score of HAI in the group of co-infection of HBV, HCV is the highest in the four groups(12.62?3.88). The score of HAI in the group which is not infected by HBV, HCV is the lowest in the four groups(6.67?2.58). HBV, HCV virus infection were positively correlated with HAI(rs=0.39,P=0.0001). HBsAg and HCV were detected both in HCC and pericarcinomatous tissues. The positive rate of HBsAg in Pericarcinomatous Tissues(79%) was higher than that of in HCC tissues(23%). HCV expressions in HCC(15%) and pericarcinomatous tissues(23%) had no differences. Conclusions As for the tissues of liver cancer with virus infection background, the HAI is obviously higher than that without virus infection background. HBV, HCV virus infection were correlated with HAI significantly, perennial virusemia will aggravate pathological changes of liver tissue.
