Resumen
Owing to pegylated interferon (PegIFN)-free direct-acting antivirals (DAAs) against chronic hepatitis C virus infection, a sustained virological response (SVR) rate >95% can be attained with a satisfactory tolerability and shorter treatment duration. However, it still remains controversial whether there is any difference in prognosis depending on treatment regimens?PegIFN or DAAs. After adjusting for imbalance between patients treated with PegIFN-based vs. DAA-based regimens, the post-SVR risk of hepatocellular carcinoma development was comparable according to treatment regimens. Furthermore, the risk was also similar between patients treated with sofosbuvir-based vs. sofosbuvir-free DAA regimens. Further studies with a longer follow-up period are required.
