Gel cushion may shield rectum during prostate cancer radiation
NCT ID NCT05323747
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This completed study tested a hydrogel spacer placed between the prostate and rectum in 20 men undergoing radiation for prostate cancer. The goal was to see if the spacer reduces radiation reaching the rectum. Researchers compared rectal radiation exposure before and after inserting the spacer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hydrogel spacer
- What this could lead to
- If successful, this spacer could help reduce rectal damage during prostate cancer radiation, making treatment safer.
- What could go wrong
- This is a small, early study with only 20 participants. It only measures radiation exposure, not long-term patient outcomes or side effects.
