- W2947950421 abstract "1510 Background: Despite antiviral treatment has been shown to reduce hepato- cellular carcinoma (HCC) recurrence after curative treatment for hepatitis B virus (HBV)-related HCC in patients with high preoperative HBV-DNA levels, it is still unclear whether antiviral therapy is useful in reducing recurrence in patients with low preoperative HBV-DNA levels. Methods: In this randomized controlled trial, 200 patients who underwent curative resection for HCC with low baseline HBV-DNA levels were ran- domly assigned to receive preemptive antiviral therapy or not. The primary endpoints were recurrence-free survival. This study was censored on March 31, 2015 when all surviving patients had a minimum follow-up of 60 months. The analysis was done on an intention-to-treat basis. Results: The baseline clinical, laboratory, and tumor characteristics of the 2 groups were comparable. The 1-, 3-, and 5-year recurrence-free survival rates for the antiviral group and the control group were 85.9%, 55.2%, and 52.0% and 80.6%, 40.9%, and 32.3%, respectively. The corresponding overall survival rates for the 2 groups were 94.0%, 75.7%, and 64.1% and 90.0%, 62.4%, and 43.7%, respectively. The recurrence-free survival and overall survival for the antiviral group were significantly better than the control group (P 1/4 0.016, P 1/4 0.004, respectively). After adjusting for confounding prognostic factors in a Cox model, the relative risks of recurrence and death for antiviral treatment were 0.601 [95% confidence interval (CI), 0.409– 0.884; P 1/4 0.010] and 0.509 (95% CI, 0.333–0.778; P 1/4 0.002), respectively. Antiviral therapy was an independent protective factor of late tumor recur- rence (hazard ratio [HR] 1/4 0.316, 95% CI 0.157 – 0.637; P 1/4 0.001) but not of early tumor recurrence (HR 1/4 0.782, 95% CI, 0.493–1.240; P 1/4 0.296). Conclusions: In patients with low preoperative HBV-DNA levels, antiviral therapy significantly reduced HCC recurrence after R0 hepatic resection.
