First seen Feb 01, 2026 · Last updated May 09, 2026 · Updated 16 times

Summary

This study compares a shorter, 3-week course of radiation before surgery to the standard 5-week course for people with soft tissue sarcomas. The goal is to see if the shorter schedule leads to similar wound healing after surgery and keeps the cancer from coming back just as well. About 168 participants will be randomly assigned to one of the two radiation schedules.
