[Association of liver cirrhosis, hepatitis B virus infection and hepatocellular carcinoma--immunohistochemical study].

In order to assess frequency and importance of the presence of alpha fetoprotein (AFP) and AlAChy as well as hepatitis B virus (HBV) infection antigens in the tissue of hepatocellular carcinoma (HCC) and in the liver tissue outside a tumour, there have been performed retrospective light-microscopic and immunohistochemical examinations of the liver tissue in 65 cases of HCC (39 autopsy and 26 biopsy cases). The finding of AlAChy in 100% of autopsy cases of HCC and 80.7% of biopsy cases of HCC compared with the presence of AFP in 33% of autopsy and 61.5% of biopsy cases point out that AlAChy is a more sensitive marker than AFP in diagnosing HCC. The presence of HBV infection antigens in 43.5% of autopsy cases and 23.5% of biopsy cases of HCC point to an important role of HBV infection in development of HCC in the studied population.
