Abstract
It is well known that primary hepatocellular carcinoma could be derived from chronic hepatitis and liver cirrhosis in epidemiologic studies. However, it is still not clear what kinds of hepatocyte are premalignant cells. Recently we have focused on liver cell dysplasia as a possible premalignant cell, and showed localization of α-fetoprotein in the cytoplasma of these cells. Although the dysplastic cells were often seen in the liver of chronic active hepatitis, hepatitis B virus associated DNA polymerase activity was also significantly high in the sera from the patients with chronic active hepatitis. In this paper, we discuss the possible role of hepatitis B virus through hepatocarcinogenesis in human.
