| Abstract: | Eight patients with primary hepatocellular carcinoma (PHC) whose blood was positive for hepatitis B surface antigen (HBsAg) received treatment with cyclophosphamide, adriamycin, and 5-fluorouracil. In 4 cases, a rise in serum HBsAg titer occurred after chemotherapy. In 2 cases involving drug-related leukopenia, the rise in HBsAg titer was marked and associated with a sharp rise in the serum transaminase level (SGOT), up to 1700 in 1 case. Lower-dosage chemotherapy was safely resumed after SGOT had returned to pretreatment levels. No evidence of immunodeficiency after chemotherapy was revealed by in vitro testing of lymphocyte and granulocyte function, percentage of circulating T-cells, and immunoglobulin and complement levels. All 8 cases were negative for e antigen (eAg) and 4 were anti-positive. In 3 of 4 cases, anti-e became negative after chemotherapy, but all remained eAg negative. The negative eAg tests in these cases of PHC suggest they are not highly infectious, in spite of increased HBsAg titers in blood following chemotherapy. |
