IFNA1 and hepatocellular carcinoma: The one- and two-year HCC recurrence rate was higher in the DAA arm than in the Peg-IFN/RBV arm (48.1%, 58.4% vs. 20.6%, 45.4% respectively, Log-rank test, p = 0.002), as seen in Figure 2A. In the Peg-IFN/RBV arm, patients with and without SVR had comparable HCC recurrence rate (51.8% vs. 51.2%, p = 0.9560).
