Patients were divided into antiviral and non-antiviral groups based on whether they received nucleos(t)ide analogue (NA) treatment when they were diagnosed with HCC in our hospital for the first time. We used 1:4 frequency matching by age, gender, tumor size, Barcelona Clinic Liver Cancer (BCLC) staging, anti-tumor therapy, cirrhosis, diabetes, and hyperlipoidemia to compare the antiviral (n = 366) and non-antiviral (n = 100) groups. A Cox multivariate regression analysis was employed to evaluate the effects of NA therapy on the hazard ratio (HR), and the Kaplan–Meier survival curve was used to determine the mortality risk in patients with HCC. A Log rank test was performed to analyze the effects of NA therapy on the survival rate of patients with HCC.Results: After propensity score matching, the 1-, 3-, and 5-year overall survival (OS) rates for the antiviral and non-antiviral groups were 82.5%, 68.6%, and 52.2%, and 61.0%, 51.0%, and 38.0%, respectively. The l-year progression-free survival (PFS) rates for the two groups were 68.0% and 47.0%, respectively. The OS of the antiviral group was significantly higher than that of the control group (P < 0.001, P = 0.001, and P = 0.013, respectively). The 1-year PFS for the antiviral group was also significantly better than that for the non-antiviral groups (P = 0.005). After adjusting for confounding prognostic factors in the Cox model, the HR of 5-year death after antiviral treatment was 0.721 (95% confidence interval [CI], 0.530– 0.980, P = 0.037). Antiviral therapy is an independent protective factor for 5-year mortality in patients with HCC and low-level viremia.Conclusion: Antiviral therapy significantly reduced mortality in HCC patients with low HBV-DNA levels.Keywords: antiviral therapy, hepatitis B virus, low-level viremia, hepatocellular carcinoma, prognosis, nucleos(t)ide analog
