Hepatitis B virus surface and core antigens in the liver of primary hepatocellular carcinoma cases in Virginia.
Zenker-fixed paraffin-embedded sections of biopsy liver tissue from 64 cases of primary hepatocellular carcinoma (PHC) were stained for hepatitis B surface antigen (HBsAg) and for hepatitis B core antigen (HBcAg) by histochemical and/or immunohistochemical techniques in a retrospective study. PHC arose in livers with postnecrotic cirrhosis in 30 (46.9%) cases. Controls included liver biopsy sections from 123 miscellaneous liver disorders and from 67 randomly selected autopsy specimens, none of which were known to be associated with hepatitis B virus (HBV) infection. HBsAg was detected in tumorous hepatocytes in only one of the 64 cases of PHC. HBsAg was identified in nontumorous hepatocytes of 8 (20%) of 40 specimens that contained adequate nontumorous liver tissue. All of these HBsAg positive cases of PHC were associated with cirrhosis. Thus HBsAg was detected in 8 (33.3%) of 24 cases of PHC with cirrhosis, but in none of the remaining 16 cases without cirrhosis. HBcAg was not detected in the hepatocytes of those HBsAg positive PHC cases tested. Our results suggest that HBV infection may successively lead to chronic hepatitis, cirrhosis and ultimately PHC.
