Aim: New hormonal agents are available for treating metastatic castration-resistant prostate cancer (mCRPC). We aim to define the incidence and relative risk (RR) of cardiovascular events in mCRPC patients treated with these agents. Methods: Prospective studies were identified by searching the MEDLINE/PubMed, Cochrane Library and ASCO Meeting abstracts. Combined relative risks (RRs) and 95% confidence intervals (CIs) were calculated using fixed- or random-effects methods. Results: We included six articles in this meta-analysis covering a total of 6735 patients who were used to evaluate cardiac toxicity. The use of new hormonal agents was associated with an increased risk of all grades of such toxicity (RR = 1.32, 95% CI, 1.08-1.60; p = 0.006) compared to a placebo, even if the absolute difference in terms of incidence was small at 14.8% versus 11.5%, respectively. No increased risk of grade 3-4 events (RR = 1.35, 95% CI, 0.90-2.03; p = 0.15) was observed.A total of 7830 patients were used to evaluate hypertension, and it was found that the use of new hormonal agents compared to a placebo was associated with an increased risk of all-grades (RR = 1.84, 95% CI, 1.37-2.46; p <. 0.001) and grade 3-4 events (RR = 1.77, 95% CI, 1.13-2.77; p = 0.01). The absolute incidence was 12.5% versus 7.5% for all-grades and 3.7% versus 2.4% for grade 3-4. Conclusions: This analysis revealed a significant increase in the incidence and RR of cardiovascular toxicity in mCRPC treated with new hormonal agents as opposed to a placebo, even though the occurrence of all- and grade 3-4 events rose only 14% and 4%, respectively. Follow-ups for the onset of treatment-related cardiovascular events should therefore be considered in these patients.
