Purpose: To evaluate the clinical benefit of Radium-223 (Ra-223) in delaying symptomatic skeletal events (SSEs) in patients with metastatic castration-resistant prostate cancer (mCRPC).
Procedure: A systematic search was conducted in PubMed and Cochrane Library to identify studies on Ra-223 in mCRPC patients with bone metastases up to March 10, 2023. The pooled incidence and time to first SSE were analyzed using random-effects meta-analysis.
Result: A total of 37 studies with 8,103 patients were included. The pooled incidence of SSEs was 19% (95% CI: 15 -25%).Median time to first SSE was 17.14 months (95% CI: 11.98 -23.02). Ra-223 significantly delayed SSE onset compared to placebo. Combination therapy further extended the time to first SSE.
Conclusion: Ra-223 effectively delays SSEs in mCRPC, especially in combination regimens, supporting its clinical utility.
