Summary

This study tests whether a personalized 3-week course of proton radiation before surgery for soft tissue sarcoma can reduce long-term side effects compared to standard X-ray radiation. About 110 adults in Norway will receive either proton or X-ray therapy, chosen individually for each patient. The main goal is to see if this approach lowers surgical complications within 120 days after surgery, while also tracking cancer control and quality of life.
