Could 5 days of radiation replace 25 for sarcoma patients?
NCT ID NCT06087861
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a 5-day course of radiation before surgery is as safe and effective as the standard 25-day course for adults with soft tissue sarcoma. Researchers will track complication rates and whether the cancer comes back. The goal is to make treatment faster and more convenient without compromising outcomes.
