Summary

This study follows about 500 men with advanced prostate cancer that still responds to hormone therapy. Researchers are comparing two drug combinations (apalutamide or enzalutamide plus standard hormone therapy) to see how well they work in real-world settings. The goal is to understand differences in cancer control, quality of life, and side effects like fatigue and anxiety.
