5-Day radiation before sarcoma surgery could spare healthy tissue
NCT ID NCT06905132
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a 5-day course of radiation given before surgery for soft tissue sarcoma in the arms, legs, or trunk. The goal is to see if this shorter treatment is safe and effective at controlling the cancer while preserving more healthy tissue. About 40 adults will receive radiation daily for a week, followed by standard surgery 2-6 weeks later. Researchers will monitor wound healing and tumor response.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Hypofractionated radiation therapy (a shorter, higher-dose radiation course over 5 days)
- What this could lead to
- If successful, this could offer a more convenient and less disruptive treatment option for soft tissue sarcoma patients, potentially reducing side effects and preserving healthy tissue.
- What could go wrong
- This is a small, early-phase trial with only 40 participants, so results may not apply to all patients. The shorter radiation course may not be as effective as standard treatment and could still cause wound complications or other side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Willingness and provision of informed consent via signed and dated copy. * Histologically confirmed STS of extremity or trunk. * Male or female, aged greater than or equal to 18 years old * ECOG performance status 0-3 * Meets screening criteria for receipt of radiotherapy. * Deemed eligible for wide local excision. * Patient and/or physician identified possible barriers to receiving a 5-week course of conventionally fractionated preoperative radiotherapy. Potential barriers include but are not limited to concern for local progression that could precluded or complicate limb sparing surgery, concern for distant progression that could result in patient being non-operative, financial and/or physical burden of travel for daily treatments, financial burden of time away from work or caregiving. Exclusion Criteria: * Distant metastatic disease * Prior radiation therapy in the proposed treatment area * Simultaneous treatment of another malignancy * Women who are pregnant or plan to become pregnant during the period of radiation therapy * Planned concurrent administration of chemotherapy and radiation therapy
