Summary

This pilot study looks at whether special scans (PSMA PET/MRI) and genetic tests can predict how well high-risk prostate cancer responds to hormone therapy and radiation. Thirty participants will be followed for up to 5 years. The goal is to find markers that identify poor responders early, so treatment can be adjusted.
