Background: The high postoperative recurrence rate of hepatocellular carcinoma (HCC) is a significant challenge. Patient metabolic factors are potential disease modifiers and should be examined as risk factors for postoperative prognosis. Here, we assessed the association between long-term statin use and HCC recurrence after surgical resection of hepatitis B virus (HBV)-related HCC. Methods: Patients who initially underwent curative resection for HBV-related HCC between 2005 and 2015 were recruited and followed up until December 2019. Patients were classified into statin user and non-statin user groups based on whether or not they had been prescribed statins for ≥2 years. The primary outcome was HCC recurrence, and the secondary outcome was liver-related mortality. The cumulative incidence by statin use was estimated using the Kaplan–Meier method and compared using the log-rank test. Adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using multivariable Cox regression. Results: Among 5653 patients with a median 6.1 years of follow-up, HCC recurrence and liver-related mortality occurred in 1603 and 316 patients, respectively. The 5-year cumulative incidence of HCC recurrence in the statin user group (15.9%) was significantly lower than that in the non-user group (21.3%; p =.019). From multivariable Cox regression analysis, statin use was significantly associated with a reduced risk of HCC recurrence (aHR 0.77, 95% CI: 0.61–0.98; p =.035) and liver-related mortality (aHR 0.48, 95% CI: 0.25–0.90; p =.023). Conclusion: Long-term statin use was significantly associated with reduced risk of HCC recurrence and liver-related mortality after curative resection of HBV-related HCC.
