Summary

This study reviewed medical records from over 1,300 men with metastatic prostate cancer that still responds to hormone therapy. Researchers wanted to see how long patients actually take the pills apalutamide or enzalutamide when prescribed by their own doctors in routine care. The goal is to understand real-world treatment patterns, not to test a new drug.
