[The expression of hepatitis C antigen in hepatitis and liver cancer tissues]

30 specimens of hepatocellular carcinoma (HCC) from laporotomy biopsy and 15 specimens of hepatitis from aspiration biopsy were subjected to hepatitis C (HCV) immunohistochemistry. Anti-HCV core monoclone antibodies and ABPAP detection method were used. The results showed that 5 specimens (17%) in the HCC group and 3 (20%) in the hepatitis group were positive, with a total positive rate of 18%. The expression pattern was scattered, located in the cytoplasm. There were positive signals in the para-carcinomatous tissues of the 5 positive cases of HCC, and there were scattered positive signals just inside the cytoplasm of the cancer cells in 3 positive HCC specimens.
