Key clinical point: Long-term aspirin use may reduce the risk for hepatocellular carcinoma (HCC) in patients with chronic hepatitis B virus (HBV) infection.
Major finding: After adjusting for confounding factors, aspirin use was associated with a decreased likelihood of HCC in the entire population (adjusted hazard ratio [aHR] 0.84; P = .002) and in the matched cohort (aHR 0.87; P = .01).
Study details: The data come from a cohort study including 161,673 patients aged ≥40 years with chronic HBV infection and no history of HCC, of which 9837 patients were aspirin users (for ≥3 years). A 1:4 propensity score matching yielded 9837 matched pairs of users and nonusers.
Disclosures: The study was sponsored by the Korea Health Industry Development Institute through “Social and Environmental Risk Research” funded by the Ministry of Health & Welfare. The authors declared no conflicts of interest.
