Because of the ongoing debate on the benefit of ultrasound (US) screening for hepatocellular carcinoma (HCC), we assessed the impact of screening on hepatitis C virus (HCV)‐related compensated cirrhosis patients aware of their HCV status. A Markov model simulated progression from HCC diagnosis to death in 700 patients with HCV‐related compensated cirrhosis aware of their HCV status to estimate life expectancy (LE) and cumulative death at 5 years. Five scenarios were compared: S1, no screening; S2, screening by currently existing practices (57% access and effectiveness leading to the diagnosis of 42% at Barcelona Clinic Liver Cancer stage [BCLC‐0/A]); S3, S2 with increased access (97%); S4, S2 with an efficacy of screening close to that achieved in a randomized controlled trial leading to the diagnosis of 87% of patients at stage BCLC‐0/A; S5, S3+S4. The analysis was corrected for lead‐time bias. Currently existing practices of HCC screening increased LE by 11 months and reduced HCC mortality at 5 years by 6% compared to no screening ( P = 0.0013). Compared to current screening practices, we found that: 1) increasing the rate of access to screening would increase LE by 7 months and reduce HCC mortality at 5 years by 5% ( P = 0.045); 2) optimal screening would increase LE by 14 months and reduce HCC mortality at 5 years by 9% ( P = 0.0002); 3) the combination of an increased rate of access and optimal effectiveness of HCC screening would increase LE by 31 months and decrease HCC mortality at 5 years by 20% ( P < 0.0001). Conclusion : The present study shows that US screening for HCC in patients with compensated HCV‐related cirrhosis aware of their HCV status improves survival and emphasizes the crucial role of screening effectiveness.
