NCT ID NCT04946357
First seen Mar 10, 2026 · Last updated Jun 23, 2026 · Updated 15 times
Summary
This phase 2 trial tests a shorter course of proton or carbon ion radiation (2-3 weeks instead of 5) given before surgery for extremity soft tissue sarcoma. The main goal is to see if this approach reduces wound healing problems after tumor removal. The study enrolls 42 adults with resectable sarcoma and no distant spread.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
proton or carbon ion radiation
What this could lead to
If successful, this shorter radiation schedule could become a new standard before sarcoma surgery, reducing side effects and improving quality of life.
What could go wrong
This is a small early-phase trial with only 42 participants, so results may not apply broadly. The main risk is wound healing problems after surgery, which the study is specifically measuring.
