摘要
Aim Assess impact of direct-acting antivirals introduction on outcomes after liver resection for hepatocellular carcinoma. Methods 391 patients (1991-2021) treated with resection for hepatocellular carcinoma on Hepatitis C background were divided according to receiving Hepatitis C treatment, treatment type, achievement of sustained virological response (SVR), time of resection pre- (Era 1, 1991-2011) and post-direct acting antivirals introduction (Era 2, 2012-2021). Survival was estimated with Kaplan-Meier curves, Cox regression analysis performed to identify survival predictors. Results Majority of patients had single lesion (67.8%), diameter >2cm in 60.6%, no evidence of macroscopic vascular invasion on imaging. Pathology showed vascular invasion in 69.6% of patients, 76.5% microvascular. Recurrence developed in 247 patients (63.2%). 194 patients (49.6%) achieved SVR. Overall survival at 1-, 3-, 5-years was 94.6%, 85.7%, 78.8% for patients who achieved SVR, 80.1%, 48.1%, 29.9% in those who did not (p<0.001). 220 patients (56.3%) were in Era 1, 171 (43.7%) in Era 2. Survival at 1-, 3-, 5-years was 76.1%, 49%, 36% in Era 1, 94.5%, 82.5%, 70.3% in Era 2 (p<0.001). SVR was an independent predictor of survival on multiple Cox Regression analysis. Discussion While many aspects of HCC management have evolved, SVR following direct-acting antivirals independently improves HCC resection outcomes.
