Treatment and Patient Selection for Patients with Metastatic Castration-resistant Prostate After Progression on Docetaxel and Abiraterone/Enzalutamide: When to Play Your CARD and When to Do Your PARP

For patients with metastatic castration-resistant prostate cancer (mCRPC) progressing after an androgen receptor axis–targeted therapy and docetaxel, poly (ADP-ribose) polymerase (PARP) inhibitors and chemotherapy with cabazitaxel have shown promise. We address the trials for the two approaches and consider possible sequencing of these drugs. We suggest that only patients with a BRCA2 mutation should receive a PARP inhibitor, and docetaxel or cabazitaxel should be favored in the absence of BRCA2 alterations, provided the patient is naïve to these drugs.
