Impact of New Systemic Therapies in Overall Survival in Non-Metastatic Castration Resistant Prostate Cancer: Systematic Review and Meta-Analysis.

There was a high medical need for patients with non-metastatic castration-resistant prostate cancer (nmCRPC) when several next-generation anti-androgens (apalutamide, enzalutamide, and darolutamide) demonstrated clinically relevant delays in metastasis onset. However, to date, few publications have assessed the pooled effect of these treatments on overall survival (OS).
