Abstract
BACKGROUND/ PURPOSE: Lamivudine has been recommended as prophylaxis for the reactivation of hepatitis B virus (HBV) infection in patients undergoing chemotherapy. However, information on breast cancer patients in particular has been lacking. The purpose of this meta-analysis was to assess the overall efficacy of lamivudine prophylaxis compared to untreated patients with hepatitis B S-antigen (HBsAg) seropositive breast cancer who had undergone chemotherapy. METHODS: Studies that compared the efficacy of treatment with lamivudine prophylaxis versus no prophylaxis in HBsAg seropositive breast cancer patients were identified through Medline, Cochrane, and Embase databases. RESULTS: Six studies involving 499 patients were analyzed. The rates of HBV reactivation in patients with lamivudine prophylaxis were significantly lower than those with no prophylaxis (risk ratio [RR] = 0.23, 95% confidence interval [CI]: 0.13-0.39, p < 0.00001). Patients given lamivudine prophylaxis had significant reductions in the rates of hepatitis attributable to HBV compared with those not given treatment (RR = 0.20, 95% CI: 0.08-0.47, p = 0.002). The rates of moderate and severe hepatitis in patients with lamivudine prophylaxis were significantly lower compared with those patients who had not received prophylaxis (RR = 0.25, 95% CI: 0.10-0.62, p < 0.003; RR = 0.25, 95% CI: 0.10-0.59, p = 0.002). Patients given lamivudine prophylaxis had significantly fewer disruptions of chemotherapy (RR = 0.36, 95% CI: 0.21-0.64, p = 0.0004). There was no significant heterogeneity in the comparisons. CONCLUSION: Lamivudine prophylaxis in HBsAg seropositive breast cancer patients undergoing chemotherapy is effective in reducing HBV reactivation and HBV-associated morbidity and mortality.
