Summary

This trial is looking at a new treatment for men with prostate cancer. The treatment involves giving a targeted dose of radiation to the prostate. The goal of the trial is to develop a protocol for this treatment

Who is the study for?
Men aged 18 or older with intermediate risk localized prostate cancer, Gleason score between 3+3 and 4+3, MRI stage T2 or less. They must have a visible tumor on MRI that's less than half the size of the prostate and PSA <20 ng/ml. Short-term hormone therapy is allowed.
What is being tested?
The trial tests a new way to give radiotherapy for prostate cancer using an MR Linac machine. It aims to tailor the radiation dose specifically to each patient's tumor, potentially reducing side effects by either increasing or decreasing the dose as needed.
What are the potential side effects?
Potential side effects include acute and late urinary (GU) and gastrointestinal (GI) toxicity which can affect bladder and bowel function respectively, as well as possible impacts on sexual quality of life.
