This study is about using a special kind of radiation treatment called focal stereotactic body radiotherapy (SBRT) to help men with prostate cancer that has come back after they already had radiation treatment. Prostate cancer is a disease where cells in the prostate grow uncontrollably. The study looks at how safe and effective this treatment is, focusing on side effects and how well it works to control the cancer. SBRT is a precise way to deliver radiation to the cancer, and it’s less invasive, meaning it’s not like surgery where you cut into the body. The study involves 60 patients and lasts over 6 years.

• The study requires a few tests like PET-PSMA and MRI scans to check the cancer location.
• Participants need to have an empty bladder and rectum during treatment planning.
• The study does not routinely require hormonal treatment.

If you have prostate cancer that has come back after radiation and meet the study's criteria, this could be an option to consider. It could help expand treatment options in the future.
