Abstract
Background and Aims
The influence of direct-acting antivirals (DAAs) on chronic hepatitis C (CHC)-related hepatocellular carcinoma (HCC) remains controversial. We investigated the effect of eradicating CHC using DAAs on treatment outcomes in patients with CHC-related HCC treated with transarterial chemoembolization (TACE).
Methods
This nationwide, multi-center, retrospective study recruited patients with CHC-related HCC treated with TACE as the first-line anti-cancer treatment, and who achieved a sustained virological response (SVR) using DAAs (DAA group) between 2006 and 2017. Patients achieving an SVR following interferon-based treatment (IFN group) and those without treatment (control group) were also recruited for comparison.
Results
A total of 425 patients were eligible for the study. Of these, 356 (83.8%), 26 (6.1%), and 43 (10.1%) were allocated to the control, IFN, and DAA groups, respectively. A multivariate analysis showed that liver cirrhosis, segmental portal vein thrombosis, and larger maximal tumor size independently predicted an increased risk of progression (all p < 0.05), whereas, the DAA group (vs. IFN and control groups) independently predicted a reduced risk of progression (hazard ratio (HR) = 0.630, 95% confidence interval 0.411–0.966, p = 0.034). The cumulative incidence rate of HCC progression in the DAA group was significantly lower than that in the IFN and control groups (p = 0.033, log-rank test). In addition, the DAA group (vs. IFN and control groups) was independently associated with a reduced risk of mortality (p = 0.042).
Conclusions
DAA treatment provided significantly prolonged progression-free survival in patients with CHC-related HCC treated with TACE compared to that in patients administered IFN or no treatment.
