摘要
Since direct-acting antiviral agents(DAAs)have been introduced into hepatitis C virus treatment,the sustained viral response(SVR)rate has significantly increased to more than 95%.Scientific evidence supports the idea that SVR after interferon therapy has beneficial effects related to cirrhosis progression,resulting in a reduction in the incidence of hepatocellular carcinoma(HCC).However,a significant debate exists related to DAA impact on HCC development.We reviewed the current literature highlighting the controversial data related to DAA association with de novo HCC occurrence or recurrence and possible pathophysiology of HCC related to DAAs.After a review of the published literature,we believe that the current evidence does not confirm or repudiate a higher rate of de novo HCC occurrence or recurrence related to DAA therapy.More trials are needed to determine if there is an association between HCC occurrence or recurrence and DAA or if it is related to preexisting liver cirrhosis.
