Abstract

Whether bleeding should be considered a sufficient sign to justify thorough cancer surveillance in atrial fibrillation (AF) patients receiving nonvitamin K antagonist oral anticoagulants (NOACs) remains unclear. We investigated the relationships between bleeding events and new-onset cancers in AF patients receiving NOACs in a prospective cohort (n = 395, mean follow-up duration of 2.8 years). There were 18 patients who were diagnosed with new-onset cancers 584 ± 372 days after the initiation of NOACs. The patients with new-onset cancers had higher HAS-BLED scores (no, preexisting and new-onset cancer: 1.51 ± 0.81, 1.69 ± 0.87, and 2.11 ± 0.96, respectively; p = 0.006) and a higher incidence of bleeding events (22%, 33%, 67%, respectively; p<0.001) than did patients without new-onset cancers. Bleeding events that preceded the diagnosis of new-onset cancers were independently correlated with new-onset cancers (odds ratio: 7.89, p = 0.001) in the multivariate logistic regression. More than half of the patients (61%) with new-onset cancers had either a significant period of drug interruption for at least 2 months or discontinued NOACs. In conclusions, bleeding in AF patients receiving NOACs could be an alerting sign of new-onset cancers and should prompt the initiation of thorough surveillance to detect early cancers.
