Abstract

Background: Direct-Acting antiviral (DAA) treatment has revolutionized hepatitis C virus (HCV) care. We aimed to evaluate the risk for the development of hepatocellular carcinoma (HCC) in patients aged 75-84 years with chronic hepatitis C after HCV elimination. Methods: This multicenter cohort study included 2405 consecutive patients with chronic hepatitis C without a history of HCC who achieved HCV elimination by DAAs. Patients in whom HCC developed within 1 year of DAA initiation were excluded. Propensity score matching analysis was used to evaluate differences in HCC risk between patients aged 75-84 versus 60-74 years. Results: The median observational period was 3.5 years. Among patients aged 75-84 years with a high Fibrosis-4 (FIB-4) index (≥3.25 at baseline), there was no significant difference in the annual incidence of HCCs between groups with an FIB-4 index ≥3.25 (2.75 per 100 person-years [PY]) versus <3.25 (2.16 per 100 PY) at 12 weeks after the end of treatment, unlike the results in those aged 60-74 years (3.61 and 1.51 per 100 PY, respectively) (adjusted hazard ratio, 2.20; P =. 04). In 495 pairs matched by propensity score matching, in patients without cirrhosis, the cumulative HCC incidence was significantly higher in the 75-84-year than in the 60-74-year age group (P =. 04). Conclusions: Older patients aged 75-84 years remained at high risk for the development of HCC, even after HCV elimination and the improvement of the FIB-4 index to <3.25.
