Daily Adaptive Radiation Therapy for Prostate Cancer

This study is testing a new way to deliver radiation therapy called daily adaptive SBRT with urethral sparing (DEVICE) for men with low or intermediate risk prostate cancer. This treatment adjusts the radiation plan each day based on imaging to protect the urethra (the tube that carries urine out of the body). The main goal is to see if this approach reduces urinary side effects, which will be measured by a questionnaire 90 days after treatment ends. You might be able to join if you are a man aged 18 or older with biopsy-proven prostate cancer, a prostate size of 80cc or less, and a low urinary symptom score. The study plans to enroll 132 participants.
