A 9-year-old boy with non-resectable hepatocellular carcinoma was treated with irradiation and intra-hepatic arterial infusion of antitumor agents. His blood was positive for hepatitis B surface antigen (HBs Ag), but negative for hepatitis B e antigen (HBe Ag). Maternal transmission was suspected, because his mother's blood was positive for HBs Ag and his grand mother died from hepatic cirrhosis. The patient received a total dose of 4000 rad in 30 fractions. A chemotherapy cycle consisted of 5-FU (6 mg/M2/day, given continuously), EX (300 mg/M2, given on 1st, 3rd, 5th, 7th, and 9th week), VCR (1.5 mg/M2, on 2nd, 4th, 6th, 8th, and 10th week), and ADM (30 mg/M2, on 13th and 16th week). Since 6 months after the initiation of the chemotherapy, alpha-fetoprotein has become negative (less than or equal to 100n g/ml), and now, 2 years and 11 months after the diagnosis was settled, the patient remains a disease free state. His blood continues to be positive for HBs Ag.

A 62-year-old Japanese man who was positive for hepatitis B surface antigen (HBsAg) and anti-HBe antibody, underwent chemotherapy for non-Hodgkin's lymphoma (NHL). Mutations were detected in the precore region (nt1896) of HBV. Because steroid-containing regimen may cause reactivation of hepatitis B virus (HBV) and hepatitis may progress to be fulminant after its withdrawal, we administered CHO (CPA, DOX and VCR) therapy and the patient obtained complete response. However, he developed acute exacerbation of hepatitis due to HBV reactivation. Recovery was achieved with lamivudine (100 mg/d) and plasma exchange. The present case suggests that acute exacerbation of hepatitis can occur with steroid-free regimen. Because the efficacy of the prophylactic use of lamivudine has been reported and the steroid enhances curability of malignant lymphoma, the steroid containing regimen with prophylaxis of lamivudine should be evaluated further.
