Summary

This trial will examine a shorter course of radiation to treat soft tissue sarcomas. Instead of 25 days, it may only need 5.

Who is the study for?
This trial is for adults over 18 with confirmed soft tissue sarcoma in limbs, trunk, or retroperitoneum. Participants must have a life expectancy of at least 6 months and be fit enough for standard preoperative radiation and surgery. Women able to bear children need a negative pregnancy test. Those who've had prior radiation in the area or plan to use other cancer treatments like chemo alongside can't join.
What is being tested?
The study tests the safety and effectiveness of a short, 5-day course of preoperative external beam radiotherapy for soft tissue sarcoma patients compared to the usual longer treatment that takes about 25 days.
What are the potential side effects?
Potential side effects may include skin changes, fatigue, swelling in treated areas, pain or discomfort during treatment sessions. Long-term effects could involve changes to bone or muscle structure and function.
