Summary
This study tests a new way to give radiation before surgery for retroperitoneal sarcoma, a rare tumor deep in the abdomen. About 80 adults will receive either proton or photon radiation, with a higher dose to high-risk areas of the tumor. The goal is to find the safest highest dose and see if this approach helps control the tumor better while reducing side effects.
