New 3-Week radiation plan aims to cut side effects for sarcoma patients
NCT ID NCT07169344
First seen Jun 27, 2026 · Last updated Jun 27, 2026
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.

Inclusion Criteria: 1. ≥ 18 years of age at the time of informed consent. 2. Histological diagnosis of STS, except rhabdomyosarcoma and Ewing sarcoma. Pleomorphic rhabdomyosarcomas are eligible. 3. Primary tumor localized in head, neck, extremity, girdle and/or trunk wall. 4. Measurable disease according to RECIST v1.1. 5. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 or 2. 6. Before patient registration, written informed consent must be given according to national and local regulations. 7. Ability to fill in patient questionnaires and comply with study procedures, including travelling to Bergen or Oslo for PBT. Exclusion Criteria: 1. Locoregional or distant metastasis as assessed by CT and/or MRI at time of diagnosis. Patients with lung nodules \<10 mm of uncertain etiology may be included. 2. Prior or concurrent malignant disease whose natural history or treatment have the potential to interfere with the safety or efficacy assessment of this clinical trial are not eligible. Patients with a history of breast cancer, requiring continued hormonal treatment (e.g. anti-estrogen or an aromatase inhibitor) may be included. Patients with a history of prostate cancer, requiring continued support with luteinizing hormone releasing hormone (LHRH) agonists, with or without androgens, may be included. 3. Previous radiotherapy to the primary tumor region. 4. Patients with pacemakers and/or implanted defibrillators. 5. Administration of systemic cancer therapy (i.e. chemotherapy, targeted therapy or immune therapy) within 14 days prior to the first fraction of radiotherapy. 6. Patients not able to give an informed consent or comply with study regulations as deemed by study investigator.
