Perioperative antiviral therapy improves the prognosis of HBV DNA-negative patients with HBV-related hepatocellular carcinoma

Abstract

ABSTRACT Objective To investigate the effect of perioperative antiviral therapy on the prognosis of hepatitis B virus (HBV) DNA-negative patients with HBV-related hepatocellular carcinoma (HCC). Methods The clinical data of 140 patients who were positive for hepatitis B surface antigen (HBsAg) but negative for HBV DNA before partial hepatectomy were retrospectively analyzed. Propensity score matching (PSM) was used to eliminate the influence of confounding factors on prognosis. Postoperative liver function, HBV reactivation rate, recurrence-free survival (RFS) and overall survival (OS) were compared between antiviral and non-antiviral therapy groups. Results Compared with the non-antiviral therapy group, the antiviral therapy group had a lower rate of HBV reactivation and better postoperative liver function (P < 0.05). The 1-year, 2-year and 3-year survival rates of the antiviral therapy group were better than those of the non-antiviral therapy group before or after PSM (P < 0.05). Prognostic analysis excluding 11 patients with HBV reactivation showed that perioperative antiviral therapy could significantly improve OS (P = 0.004), but had no significant effect on RFS (P = 0.056). Multivariate analyzes showed that antiviral therapy was associated with better OS. Conclusion Perioperative antiviral therapy can significantly reduce the risk of HBV reactivation and improve postoperative liver function, RFS and OS.
