Summary

This trial will study whether reducing the amount of radiation delivered to normal tissues during prostate cancer treatment improves patient outcomes.

Who is the study for?
This trial is for men with low or intermediate risk localized prostate cancer, specifically those with a Gleason score of 7 or less, PSA under 20, and no more than half of biopsy cores involved with tumor. It's not for men who've had hip replacements, inflammatory bowel diseases, severe reactions to prostate biopsies, or are on certain anticoagulant therapies.
What is being tested?
The study tests if using advanced MRI in planning and daily CBCT imaging during treatment can improve outcomes by reducing radiation doses to non-cancerous parts like the rectum and bladder. The trial has two stages: first integrating advanced imaging without changing dose plans; secondly reducing doses to healthy tissues.
What are the potential side effects?
While the trial focuses on minimizing side effects by precisely targeting radiation, potential risks may include typical radiotherapy side effects such as skin irritation at the treatment site, fatigue, urinary issues, and gastrointestinal discomfort.
