Abstract
Serological evidence of hepatitis B virus (HBV) infection and serum alphafetoprotein (AFP) were assayed in sera from 112 Korean patients with primary hepatocellular carcinoma (PHC) and from 63 age- and sex-matched controls. Serological evidence of HBV infection was found in 100% of PHC patients and in 97% of controls. The majority of PHC patients (87%) were positive for hepatitis B surface antigen (HBsAg). In contrast, only 14% of control individuals were positive for HBsAg, but 82% were positive for antibody to HBsAg (anti-HBs). Hepatitis B e antigen (HBeAg) was detected in a high percentage (38%) of HBsAg-positive PHC patients, but in none of the nine HBsAg-positive control individuals. Serum AFP was detectable in 83% of PHC patients but in only one of 63 controls (1.5%). These results document that HBV infection may be the major factor in the development of PHC in this country.
