Read our Prostate Cancer research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing radiation therapy — either proton radiation or conventional radiation — given after prostate surgery to help prevent prostate cancer from returning or to treat cancer that has already come back. The study will look at how well the treatment works and what side effects patients experience, with treatment plans tailored based on whether the cancer is considered high-risk or low-risk.
After prostate surgery, some men face a higher chance that cancer will return. This trial is trying to determine the best way to use radiation therapy to lower that risk and improve long-term outcomes.

Depending on whether your cancer is high-risk or low-risk, and whether the radiation is being given after surgery or to treat returning cancer, you will receive a course of radiation therapy targeting your prostate bed. High-risk patients will receive multiple types of radiation (conventional and proton boost), while low-risk patients will receive proton radiation alone. The treatment typically involves several weeks of daily or near-daily radiation sessions as an outpatient.
