This study compares two types of radiation treatments for men with prostate cancer that has either returned or spread a bit. **Stereotactic Body Radiation Therapy (SBRT)** is a special kind of radiation that targets tumors precisely and can be done in about 1-2 weeks. **Hypofractionated Radiotherapy** delivers higher doses over 4-6 weeks. Both aim to minimize damage to healthy tissue while treating cancer. The study checks which treatment has fewer side effects, especially those affecting the urinary and digestive systems. **Key points to consider:** - **Duration:** SBRT takes 1-2 weeks, while hypofractionated therapy takes 4-6 weeks. - **Visits:** Regular follow-ups are required, initially every 3 months, then annually for up to 5 years. - **Risks:** Possible side effects include urinary and digestive issues, which are monitored closely during the study. Eligibility requires a confirmed diagnosis of prostate cancer with specific conditions. Certain medical histories, like previous pelvic radiation or serious heart issues, may exclude participation. Participants must be able to start treatment within 120 days of joining the study.
