Radiation treatment comparison for metastatic prostate cancer
Official title: Consolidative Prostate Radiotherapy in Patients With Metastatic Prostate Cancer
Run by University Health Network, Toronto · NCT05656794 · Data updated 2026-11-12
This study is testing whether getting radiation treatment every other day for two weeks causes different side effects compared to getting it once a week for six weeks in men with metastatic prostate cancer.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include adults aged 18 and older with histologically-proven metastatic prostate cancer and specific criteria regarding the volume and location of metastases.
✕Probably not a fit
Patients with prior pelvic radiotherapy or conditions that contraindicate radiotherapy may not benefit from this study.

What this trial studies
This phase II trial investigates the side effects of two different radiation treatment schedules for patients with metastatic prostate cancer. Participants will receive radiation either every other day for two weeks or once weekly for six weeks. The study aims to determine if the frequency of treatment affects the side effects experienced by patients. It is a randomized trial, meaning participants will be assigned to one of the two treatment groups by chance.
Why it matters
Potential benefit: If successful, this study could help optimize radiation treatment schedules to minimize side effects for patients with metastatic prostate cancer.
How similar studies have gone: While this approach is being tested in this specific context, similar studies have shown varying results in optimizing radiation schedules for cancer treatment.
