NCT ID NCT07300631
First seen Jun 27, 2026 · Last updated Jul 31, 2026 · Updated 2 times
Summary
This study follows 320 men with prostate cancer who receive a hydrogel spacer (SpaceOAR) before radiotherapy. The spacer is placed between the prostate and rectum to protect healthy tissue. Researchers will collect data from medical records and patient questionnaires over three years to track side effects and long-term safety. The goal is to provide real-world evidence on how well the spacer works and its risks.
