    Abstract:
    BACKGROUND & AIMS: To assess the risk for the development of hepatocellular carcinoma (HCC) according to the underlying liver status and on-treatment viral response during long-term lamivudine therapy in patients with hepatitis B virus-related liver disease. PATIENTS AND METHODS: Between March 1997 and February 2005, a total of 872 patients were treated with lamivudine for more than one year. Between 1983 and 1998, a total of 699 patients were enrolled as historical controls. RESULTS: For patients with compensated cirrhosis, HCC occurred in 4.9% (5/103) of cases with sustained viral suppression (persistently <141,500 copies/ml), 11.8% (20/170) in cases with viral breakthrough, and 19.4% (7/36) in cases with a suboptimal response (persistently 141,500 copies/ml): the mean follow-up was 5.1+/-2.7, 5.4+/-2.3, and 3.7+/-1.8 years, respectively. For the control group, HCC developed in 25.0% (37/148) of the cases during a mean follow-up of 6.1+/-4.3 years. Thus, the annual incidence of HCC was 0.95%, 2.18%, 5.26%, and 4.10% in patients with sustained viral suppression, viral breakthrough, suboptimal response, and the control group, respectively. The cumulative incidence of HCC in patients with sustained viral suppression was significantly lower than in patients with a suboptimal response and the controls (p=0.002 and p=0.005, respectively). In patients without cirrhosis and with decompensated cirrhosis, the preventive effects of lamivudine on the development of HCC were not observed (p=0.446 and p=0.123, respectively). CONCLUSION: Lamivudine therapy reduced the incidence of HCC in patients with compensated cirrhosis when the viral suppression was sustained.
