MR-Linac-Guided Radiotherapy for Recurrent Prostate Cancer

This study, called TUMORNATOR II, is looking at a new way to treat prostate cancer that has come back after previous radiation therapy. It uses MR-Linac-guided Stereotactic Body Radiation Therapy (SBRT), a precise type of radiation, along with Androgen Deprivation Therapy (ADT) using medications like Leuprolide, Degarelix, or Relugolix. The main goal is to see how safe this treatment is and to track any urinary side effects over two years. You might be able to join if you are a man aged 18 or older with prostate cancer that has returned after prior external beam radiation therapy. The study plans to enroll 28 participants, but its current status is unclear.
