AimThe impact of sustained virologic response (SVR) on surgical outcomes for patients with hepatitis C virus (HCV)‐related hepatocellular carcinoma (HCC) remains controversial. This study aimed to evaluate the influence of SVR on long‐term surgical outcomes after hepatectomy.MethodsThis multicenter study included 504 patients who underwent curative resection for HCV‐related HCC. Patients with a history of HCC treatment, HBV infection, poor liver function, and tumor with major vascular invasion were excluded. Long‐term surgical outcomes (overall survival [OS] and recurrence‐free survival [RFS]) among patients who achieved SVR before hepatectomy (Pre‐SVR group: 58 patients), after hepatectomy (Post‐SVR group: 54 patients), and without SVR (Non‐SVR group: 186 patients) were compared after adjusting for 13 confounding factors. Using the surgically resected specimens, comparison of the pathological changes in liver fibrosis between the first and second hepatectomy were analyzed.ResultsPatients with SVR were younger, had better liver function, and less liver fibrosis compared to patients without SVR. Propensity score‐matched OS and RFS were significantly better in Pre‐SVR group than Non‐SVR group (P = .029 and P = .009, respectively). Inverse probability‐weighted OS and RFS were also significantly better in the Post‐SVR group (P = .001 and P = .021, respectively) than in the Non‐SVR group. Histopathological evaluation revealed that only the patients with SVR had regression of liver fibrosis (P < .05).ConclusionAchievement of SVR before or after hepatectomy is essential for improving long‐term surgical outcomes in patients with HCV‐related HCC.
