Abstract
BACKGROUND

Prospective studies of the long-term outcomes of patients with hepatitis C virus (HCV) infection after treatment with interferon-based therapy (IBT) or direct-acting antivirals (DAA) are limited in many Asian countries.

AIM

To elucidate the incidences of hepatocellular carcinoma (HCC) and death/transplantation based on treatment with IBT or DAA, to compare the outcomes of the sustained virologic response (SVR) to IBT and DAA, and to investigate outcome-determining factors after SVR.

METHODS

This cohort included 2054 viremic patients (mean age, 57 years; 46.5% male; 27.4% with cirrhosis) prospectively enrolled at seven hospitals between 2007 and 2019. They were classified as the untreated group (n = 619), IBT group (n = 578), and DAA group (n = 857). Outcomes included the incidences of HCC and death/transplantation. The incidences of the outcomes for each group according to treatment were calculated using an exact method based on the Poisson distribution. A multivariate Cox regression analysis was performed to determine the factors associated with HCC or death/transplantation, followed by propensity score matching to confirm the results.

RESULTS

During a median of 4.1 years of follow-up, HCC and death/transplantation occurred in 113 and 206 patients, respectively, in the entire cohort. Compared with the untreated group, the incidences of HCC and death/transplantation were significantly lower in the IBT group [adjusted hazard ratio (aHR) 0.47, 95%CI: 0.28-0.80 and aHR 0.28, 95%CI: 0.18-0.43, respectively] and the DAA group (aHR 0.58, 95%CI: 0.35-0.96, and aHR 0.19, 95%CI: 0.20-0.68, respectively). Among 1268 patients who attained SVR with IBT (n = 451) or DAA (n = 816), the multivariable-adjusted analysis showed no differences in the risks of HCC (HR 2.03; 95%CI: 0.76-5.43) and death/transplantation (HR 1.38; 95%CI: 0.55-3.49) between the two groups. This was confirmed by a propensity score-matching analysis. Independent factors for HCC after SVR were age, genotype 1, and the presence of cirrhosis.

CONCLUSION

Treatment and achieving SVR with either IBT or DAA significantly reduced the incidences of HCC and mortality in the Asian patients with HCV infection. The risks of HCC and mortality were not significantly different regardless of whether SVR was induced by IBT or DAA.

Core Tip: Treatment and sustained virologic response (SVR) with either interferon-based treatment (IBT) or direct-acting antiviral (DAA) significantly reduced the incidences of hepatocellular carcinoma and mortality in our Asian prospective cohort. The risks of HCC and all-cause of mortality were not significantly different regardless of whether SVR was induced by IBT or DAA. After achieving SVR, age, the presence of cirrhosis, and genotype 1 hepatitis C virus infection were indicators of worse clinical outcomes.
