Summary

This study tests whether adding prostate cryoablation (freezing the tumor) and a low-dose chemotherapy drug (cyclophosphamide) to standard hormone therapy can delay cancer progression in men with newly diagnosed metastatic prostate cancer. About 104 men aged 18-80 will receive the combination treatment and be monitored for side effects and progression. The goal is to see if this approach works better than hormone therapy alone.
