Clinical Course and Survival after Liver Transplantation for Hepatitis B Virus Infection Complicated by Hepatocellular Carcinoma

Objectives and Methods : The outcome after liver transplantation for HBsAg-positive liver disease complicated by hepatocellular carcinoma is not clearly defined, and in the present study we analyzed the clinical course in 39 patients transplanted for hepatitis B virus (HBV)-re-lated liver disease (group 1) compared with 16 patients with chronic HBV and hepatocellular carcinoma (group 2) and 52 patients with primary hepatocellular carcinoma seronegative for HBsAg (group 3). Results : Despite similar pretransplant viral serology, HBV recurred more often in patients with tumor (group 2) than in nontumor cases (group 1), with 1-yr actuarial cumulative reinfection rates of 85.4% versus 65.0%, respectively ( p < 0.05). In group 2 cases, we observed a more aggressive pattern of HBV-related graft injury with a higher frequency of graft loss (56.3% vs . 12.8%, p < 0.001). Long-term outcome was worse in the group 2 cases, with 5-yr actuarial survival rates of 16.7% compared with 73.2% and 28.2% for groups 1 and 3, respectively. In group 2, recurrence of HBV in the graft, rather than tumor recurrence, was the principal cause of the high mortality observed (56.2% vs. 12.5%), which, in some cases, may have been potentiated by adjuvant chemotherapy. Conclusion : The poor outcome of patients transplanted for HBsAg-positive cirrhosis and hepatocellular carcinoma is due to HBV reinfection of the graft, rather than tumor recurrence. Antiviral agents in association with hepatitis B immunoglobulin would be the most promising approach to improving survival in this patient population.
