Core Tip
Core tip: Our meta-analysis has demonstrated that pre-chemotherapy may affect the efficacy and toxicity of abiraterone treatment in patients with metastatic castration-resistant prostate cancer. Abiraterone was associated with significantly increased radiographic-progression-free survival, objective response rate, and prostate-specific antigen response rate in the pre-chemotherapy setting when compared to the post-chemotherapy setting. In addition, abiraterone in the pre-chemotherapy setting had a significant lower risk of all-grade fluid retention and edema (P < 0.001), and hypokalemia (P < 0.001), but had a higher risk of all-grade hypertension (P < 0.001) when compared to post-chemotherapy.
