Cardiovascular Adverse Events Associated with Prostate Cancer Treatment: A Disproportionality Analysis from the Food and Drug Administration Adverse Event Reporting System Database

Abstract

Background/Objectives: Several drugs used to treat prostate cancer have been reported to cause cardiovascular adverse events, and this study sought to identify the real-world risk. Methods: This study utilized real-world data from the FAERS to analyze the association between prostate cancer treatment and cardiovascular adverse events. It evaluated men treated with LHRH agonists and antagonists, antiandrogens, androgen synthesis inhibitors, and PARP inhibitors from 2003 to 2023. This study included patients treated with leuprolide, goserelin, triptorelin, degarelix, relugolix, bicalutamide, flutamide, apalutamide, nilutamide, abiraterone, enzalutamide, olaparib, rucaparib, talazoparib, and niraparib. The main outcome measure was the reported odds ratio (ROR) of adverse cardiovascular event associated with these treatments. Results: Among the 4,049,329 unique adverse event reports, 4391 cardiovascular events were identified. Leuprolide (ROR 0.481, 95% CI: 0.423–0.547), triptorelin (ROR 0.527, 95% CI: 0.305–0.909), enzalutamide (ROR 0.393, 95% CI: 0.341–0.452), and olaparib (ROR 0.145, 95% CI: 0.054–0.386) reduced the risk of myocardial infarction. Goserelin increased the risk of myocardial infarction (ROR 2.235, 95% CI: 1.367–3.654). Degarelix and relugolix both increased the risk of heart failure (ROR 3.136, 95% CI: 2.186–4.497), and enzalutamide was associated with an increased risk of heart failure (ROR 1.305, 95% CI: 1.135–1.501). Bicalutamide increased the risk of unstable angina (ROR 3.019, 95% CI: 1.621–5.622) and heart failure (ROR 3.730, 95% CI: 3.085–4.510). Niraparib increased the risk of hypertension (ROR 4.154, 95% CI: 1.709–10.092). Conclusions: These findings underscore the need for clinicians to monitor cardiac complications in patients undergoing these therapies.
