Background: Hepatocellular carcinoma (HCC) is a major cause of morbidity and mortality among patients with cirrhosis. The risk of HCC recurrence after a complete response among patients treated with direct-acting antivirals (DAAs) has not been fully elucidated yet. Aim: To assess the risk of HCC recurrence after DAA therapy for hepatitis C virus (HCV). Methods: A systematic review across PubMed, Scopus and Scholar up to November 2020, including full-text studies that assessed the pattern of HCC recurrence after DAA therapy for HCV. Random-effect meta-analysis and univariable metaregression were applied to obtain pooled estimates for proportions and relative risk (RR) and variables influential for the outcome, respectively. Results: Thirty-one studies with 2957 patients were included. Overall, 30% (CI, 26–34%) of the patients with a history of HCC experienced HCC recurrence after DAA therapy, at mean time intervals ranging from 4 to 21 months. This result increased when going from European studies (23%, CI, 17–28%) to US studies (34%, CI, 30–38%), to Egyptian studies (37%, CI, 27–47%), and to Asian studies (33%, CI, 27–40%). Sixty-eight percent (CI, 45–91%) of recurrent HCCs developed within 6 months of follow-up since DAA treatment, among the eight studies providing stratified data. Among the studies providing head-to-head comparisons, the HCC recurrence risk was significantly lower after DAA therapy than IFN (RR, 0.64; CI, 0.51–0.81), and after DAA therapy than no intervention (RR, 0.68; CI, 0.49–0.94). Conclusions: The recurrence of HCC after DAA is not negligible, being higher soon after the end of treatment and among non-European countries. DAA therapy seems to reduce the risk of HCC recurrence compared to an IFN regimen and no intervention.

Introduction:Globally, between 64 and 103 million people are chronically infected with Hepatitis C virus (HCV), with more than 4.6 million people in the United States and is associated with more than 15.000 deaths annually. Chronic infection can result in cirrhosis and hepatocellular carcinoma.Explanation:Epidemiological studies have indicated that persistent infection with hepatitis C virus (HCV) is a major risk for the development of hepatocellular carcinoma (HCC), mainly through chronic inflammation, cell deaths, and proliferation. Despite the new direct-acting antiviral drugs (DAA’s) being able to clear the HCV, HCC recurrence rate in these patients is still observed.Conclusion:In this review we highlighted some aspects that could be involved in the onset of HCV-induced HCC such as immune system, viral factors and host genetics factors.Moreover, we focused on some of the last reports about the effects of DAA’s on the HCV clearance and their potential implications in HCC recurrence.

By pegylated interferon (PegIFN)-free direct-acting antivirals (DAAs) against hepatitis C virus (HCV) infection, a sustained virological response (SVR) rate >95% can be attained with a satisfactory tolerability and shorter treatment duration. However, it remains controversial whether there is any difference in prognosis depending on regimens—PegIFN or DAAs. We compared the probabilities of hepatocellular carcinoma (HCC) development between patients achieving an SVR by PegIFN/ribavirin (PegIFN group, n = 603) and DAAs (DAAs group, n = 479). The DAAs group was significantly older and had a higher proportion of cirrhosis than the PegIFN group. Before adjustment, the DAAs group had a higher HCC incidence than the PegIFN group (p < 0.001). However, by multivariate analyses, the DAAs (vs. PegIFN) group was not associated with HCC risk (adjusted hazard ratio 0.968, 95% confidence interval 0.380–2.468; p = 0.946). Old age, male, higher body mass index, cirrhosis, and lower platelet count were associated with increased HCC risk (all p < 0.05). After propensity score matching (PSM), a similar HCC risk between the two groups was observed (p = 0.372). We also compared HCC incidences according to sofosbuvir (SOF)-based and SOF-free DAAs, showing a similar risk in both groups before adjustment (p = 0.478) and after PSM (p = 0.855). In conclusion, post-SVR HCC risks were comparable according to treatment regimens; PegIFN- vs. DAA-based regimens and SOF-based vs. SOF-free DAA regimens. Further studies with a longer follow-up period are required.
