This study aimed to investigate the association between androgen deprivation therapy (ADT) in prostate cancer patients and subsequent cardiovascular disease (CVD) and all-cause mortality. The results showed that ADT was associated with composite CVD, myocardial infarction, stroke, heart failure, and all-cause mortality. These associations persisted in patients with low and moderate CVD risk and ADT duration longer than 7 months.
Studies have suggested that prostate cancer (PCa) patients receiving androgen deprivation therapy (ADT) are at increased risk of developing or exacerbating cardiovascular disease (CVD). We aimed to explore the association between ADT for PCa and subsequent CVD and all-cause mortality in this nationwide, longitudinal study. We also evaluated the role of cardiovascular risk and ADT duration to determine effect modification. Norwegian registry data were used to identify patients with PCa from 2008-18 and who received primary ADT in the first year after diagnosis. The associations between ADT and composite cardiovascular events, and the individual components of myocardial infarction, stroke and heart failure, in addition to atrial fibrillation and all-cause mortality, were explored using time-varying Cox regression models. We included 30 923 PCa patients, of whom 8449 (27%) received primary ADT. Mean follow-up was 2.9 and 3.8 years for CVD events and mortality, respectively. We found an association between ADT and composite CVD (adjusted HR 1.13: 95% CI 1.05-1.21), myocardial infarction (1.18: 1.05-1.32), stroke (1.21: 1.06-1.38), heart failure (1.23: 1.13-1.35) and all-cause mortality (1.49: 1.39-1.61). These associations persisted in those with low and moderate CVD risk and ADT longer than 7 months. A relationship between ADT and composite CVD and all-cause mortality was observed, especially in those with moderate CVD risk and longer treatment duration. Future studies with more detailed cancer data are needed to verify the clinical relevance of these results, especially when considering all-cause mortality within the context of treatment guidelines and benefits of ADT.
