NCT05917301

Brief Summary

This study is being done to examine whether proton therapy for certain kinds of sarcomas (extremity and trunk soft tissue) is safe and effective. As part of the study, patients will have five fractions of proton therapy before the participants have surgery for the sarcoma. The study will measure wound complications and functional outcomes / quality of life after the procedures. Patients will be asked to complete questionnaires about the treatment and quality of life from the time of enrollment until about two years after surgery. Otherwise, the participants will have standard of care follow ups with the treatment team.

Outcome Measures

Primary Outcomes (1)

  • Rate of major wound complications

    Number of major wound complications as defined by the CAN-NCIC-SR2 trial ("secondary operation under general or regional anaesthesia for wound repair (debridement, operative drainage, and secondary wound closure including rotationplasty, free flaps, or skin grafts), or wound management without secondary operation…\[including\] an invasive procedure without general or regional anaesthesia (mainly aspiration of seroma), readmission for wound care such as intravenous antibiotics, or persistent deep packing for 120 days or longer.")

    90 days after surgery

Secondary Outcomes (8)

  • Incidence of acute grade ≥3 adverse events

    2 years after treatment

  • Rate of local recurrence free survival

    1 and 2 years after enrollment

  • Rate of metastasis free survival

    1 and 2 years after enrollment

  • Rate of late grade ≥2 radiation toxicity

    median two year follow up

  • Musculoskeletal Tumor Rating Scale scores

    baseline, 2-12 weeks after end of radiation therapy, after surgery (3-6 month follow up), every 3 months during follow up for 2 years

  • +3 more secondary outcomes

Study Arms (1)

Pre-operative hypofractionated proton therapy

EXPERIMENTAL

Patients will have 5 fractions of proton therapy prior to surgical resection of their sarcoma.

Radiation: hypofractionation

Interventions

This study is being done to see if hypofractionation in treating sarcoma, will also provide patients with a faster and safer treatment outcome.
