Shorter Course, Hypofractionated Pre-Surgery Radiation Therapy in Treating Patients With Localized, Resectable Soft Tissue Sarcoma of the Extremity of Superficial Trunk

Resectable Soft Tissue Sarcoma Clinical Trial

Official title: Prospective Trial of Hypofractionated Pre-Operative Radiation Therapy for Localized, Resectable Soft Tissue Sarcoma of the Extremity or Superficial Trunk (HYPORT-STS)

Status Active, not recruiting

Clinical Trial Summary

This phase II trial studies the wound complication risk of shorter course, hypofractionated pre-surgery radiation therapy in treating patients with localized soft tissue sarcoma of the extremity of superficial trunk that can be removed by surgery. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Shorter course hypofractionated pre surgery radiation therapy may be more convenient for patients with soft tissue sarcoma than a longer course of radiation therapy, and may result in fewer complications.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine, in patients with localized, resectable soft tissue sarcoma, whether there is a non-inferior major wound complication rate for patients receiving 42.75 Gy in 15 fractions over 3 weeks compared to historical controls who received 50 Gy in conventional fractionation over 5-6 weeks.

SECONDARY OBJECTIVES:

I. To determine whether local control rates among patients treated with 42.75 Gy in 15 fractions is similar to that observed in previous studies for patients treated with 50 Gy in conventional fractionation over 5-6 weeks.

II. To determine whether patterns of local relapse, relapse free survival, overall survival, or metastatic disease free survival for patients treated with 42.75 Gy in 15 fractions are similar to previously reported studies.

III. To determine where there is a difference in pathologic response in tumor specimens treated with 42.75 Gy in 15 fractions compared to previously reported rates of hyalinization, fibrosis, or necrosis.

IV. To explore quality of life, as measured by the Functional Assessment of Cancer Therapy-General (FACT-G), financial toxicity as measured by the Comprehensive Score for financial Toxicity (COST) Instrument, and patient reported outcomes, as measured by the Toronto Extremity Salvage Score (TESS), among individuals undergoing a shorter, hypofractionated course of pre-operative radiation therapy for soft tissue sarcoma of the extremity or superficial trunk.

V. To gather subjective data on patient treatment preferences and experiences among individuals undergoing a shorter, hypofractionated course of pre-operative radiation therapy for soft tissue sarcoma of the extremity or superficial trunk.

OUTLINE:

Patients receive hypofractionated radiation therapy in 15 daily fractions over 3 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3-4 months for 2 years, every 6 months for 3 years, and then every year for up to 10 years. ;
