Abstract

Summary: Background: The incidence of hepatocellular carcinoma (HCC) in patients with a history of curatively‐treated HCC is higher than in patients with no history of HCC even after sustained virologic response (SVR). Aim: To investigate differences in the patterns of HCC development after SVR in patients with a history of curatively‐treated HCC and those with no history of HCC, based on gadolinium‐ethoxybenzyl‐diethylenetriamine pentaacetic acid‐enhanced magnetic resonance imaging (EOB‐MRI) findings. Methods: EOB‐MRI was performed in 164 patients with HCV cirrhosis who achieved SVR by interferon‐free direct‐acting antiviral (DAA) therapy just before the start of therapy. Changes in EOB‐MRI findings after SVR were compared prospectively between patients with (n = 62) and without (n = 102) a history of HCC. Results: The incidence of HCC after SVR was higher in patients with a history of HCC ( P < 0.0001). The prevalence of nonhypervascular hypointense nodules (NHHNs) by EOB‐MRI was significantly higher in patients with a history of HCC at baseline ( P = 0.05). Although there was no difference in the incidence of the hypervascularisation of baseline NHHNs to typical hypervascular HCC between patients with and without a history of HCC, the incidence of direct emergence of hypervascular HCC despite the absence of NHHNs at baseline was significantly higher in patients with a history of HCC ( P < 0.0001). Conclusion: Direct emergence of hypervascular HCC and a higher prevalence of NHHNs before DD therapy contributed to the higher incidence of HCC after SVR. (UMIN000017020).
