Duration and cost-effectiveness of hepatocellular carcinoma surveillance in hepatitis C patients after viral eradication


Background and aims: Successful treatment of chronic hepatitis C with oral direct-acting antivirals (DAAs) leads to virological cure, however, the subsequent risk of hepatocellular carcinoma (HCC) persists. Objective of the present study was to evaluate the cost-effectiveness of biannual surveillance for HCC in patients cured of hepatitis C and the optimal age to stop surveillance.
Methods: The authors developed a microsimulation model of the natural history of HCC in individuals with hepatitis C and advanced fibrosis or cirrhosis who achieved virological cure with oral DAAs. They used published data on HCC incidence, tumor progression, real-world HCC surveillance adherence, and costs and utilities of different health states. Biannual HCC surveillance using ultrasound and alpha-fetoprotein for varying durations of surveillance (from 5 years to lifetime) versus no surveillance was compared.
Results: In virologically cured patients with cirrhosis, the incremental cost-effectiveness ratio (ICER) of biannual surveillance remained below USD 150,000 per additional quality-adjusted life year (QALY) (range: USD 79,500 – USD 94,800) when surveillance was stopped at age 70, irrespective of the starting age (40–65). Compared with no surveillance, surveillance detected 130 additional HCCs in “very early”/early stage and yielded 51 additional QALYs per 1000 patients with cirrhosis. In virologically cured patients with advanced fibrosis, the ICER of biannual surveillance remained below USD 150,000/QALY (range: USD 124,600 – USD 129,800) when surveillance was stopped at age 60, irrespective of the starting age (40–50). Compared with no surveillance, surveillance detected 24 additional HCCs in “very early”/early stage and yielded 12 additional QALYs per 1000 patients with advanced fibrosis.

Conclusion: Biannual surveillance for hepatocellular carcinoma in patients cured of hepatitis C is cost-effective until the age of 70 for patients with cirrhosis, and until the age of 60 for patients with stable advanced fibrosis.
