Abstract
BACKGROUND: Antiviral therapy should reduce the recurrence of hepatitis B virus-related hepatocellular carcinoma (HBV-related HCC) after surgical resection. However, there is little research on whether various antiviral drugs have different prognostic effects in patients with HBV-related HCC after curative liver resection. The present study compared the effects of nucleotide analog (NtA) and nucleoside analog (NsA) antiviral therapies after surgical resection on the prognosis of HBV-related HCC. METHODS: A total of 1303 patients with HBV-related HCC who received curative hepatectomy at five institutes between April 2014 and April 2019 were retrospectively enrolled and analyzed. Propensity matching analysis was used to compare the outcomes of HCC patients given NsA versus NtA therapy. Subgroup analysis of patients treated with entecavir (ETV) and tenofovir disoproxil fumarate (TDF) was also performed. RESULTS: Among 1303 patients, 759 (58.2%) patients developed recurrence, and 460 (35.3%) patients died. Multivariable analyses revealed that NtA therapy significantly decreased the risk of HCC recurrence (hazard ratio [HR], 0.64; 95% confidence interval [CI], 0.51-0.80; p < 0.001) and HCC-related death (HR, 0.52; 95% CI, 0.36-0.76; p = 0.001) compared to that with NsA therapy. Subgroup analysis showed that TDF treatment was associated with significantly lower rates of HCC recurrence (HR, 0.64; 95% CI, 0.49-0.83; p = 0.001) and death (HR, 0.32; 95% CI, 0.20-0.50; p < 0.001) than ETV treatment. CONCLUSIONS: Nucleotide analog treatment, but not NsA treatment, significantly reduced the risk of HCC recurrence in patients with HBV-related HCC and improved overall survival after curative hepatic resection.
