Summary

This trial looks at whether two weeks of radiation has the same effects as 6 weeks of radiation.

Who is the study for?
Men aged 18+ with metastatic prostate cancer, either low or high volume, are eligible. They must be fit for daily activities (ECOG 0 or 1), planning to receive external beam radiation therapy (EBRT) while on hormone therapy +/- ARAT. Prior chemotherapy is okay if it was over six weeks ago. Men with active inflammatory bowel disease or conditions that rule out radiotherapy, especially prior pelvic radiation, can't join.
What is being tested?
This study compares two schedules of delivering radiation treatment for metastatic prostate cancer: one group will receive treatments every other day for two weeks and the other once weekly for six weeks. The goal is to see if side effects differ between these schedules.
What are the potential side effects?
Radiation may cause fatigue, skin reactions in treated areas, frequent urination with possible discomfort, bowel changes like diarrhea or pain during movements, and a risk of erectile dysfunction.
