Hepatitis B Virus Infection and Primary Hepatocellular Carcinoma 2 3

Ninety-three patients with biopsy-proven primary hepatocellular carcinoma (PHC) from Uganda, Zambia, and the United States were examined for serologic evidence of hepatitis B virus (HBV) infection. Patients were tested for hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs), antibody to the hepatitis B core antigen (anti-HBc), hepatitis B e antigen (HBeAg), and its antibody (anti-HBe). Active HBV infection, as indicated by positive tests for HBsAg (with or without anti-HBs) and anti-HBc (without anti-HBs), was present in 62% of PHC patients (58 of 93), in contrast with 10% of African controls (9 of 90), and less than 1% of most United States adult populations reported in the literature. The presence of HBeAg or anti-HBe was rare among PHC patients and controls.
