    Abstract:
    The serologic and tissue markers of hepatitis B virus (HBV) were studied in 50 patients in whom hepatocellular carcinoma (HCC) was confirmed at autopsy. Serologic and tissue markers included serum hepatitis B surface antigen (HBsAg), tissue HBsAg, tissue hepatitis core antigen (HBcAg), and serum antibody to HBcAg (anti-HBc). Twenty-two patients had HCC arising in alcoholic cirrhosis; 2 of the 22 (9.1%) had one or more of the HBV tissue and serologic markers. This infection rate is similar to the rate of 7.9% observed in 63 control alcoholic cirrhotic patients without HCC. In contrast, 15 of 20 (75.0%) patients with HCC in nonalcoholic chronic active liver disease showed evidence of active HBV infection. One of 8 patients with HCC in normal liver had serum HBV markers. This result indicates that there is an extremely high prevalence of HBV infection among HCC patients with nonalcoholic chronic liver disease in the U.S.A. The prevalence of HBV infection in these patients is as high as that observed in Asia and Africa. Thus, it can be concluded that the lower prevalence rate of active HBV infection in HCC patients in the U.S.A. is the result of statistical dilution of HCC-B-viral disease by the large numbers of the alcoholic cirrhotic patients with HCC, and that if chronic active hepatitis type B were as common in the United States as it is in Africa and Asia, the frequency of occurrence of HCC might also be as high.
