Randomised Trial of Volume of Post-operative Radiotherapy Given to Adult Patients With eXtremity Soft Tissue Sarcoma
- Conditions
- Sarcoma
- Interventions
- Radiation: radiotherapy
- Registration Number
- NCT00423618
- Brief Summary
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy after surgery may kill any tumor cells that remain after surgery. It is not yet known whether giving radiation therapy to a smaller area of tissue surrounding the tumor is as effective as giving radiation therapy to a wider area of tissue surrounding the tumor in treating soft tissue sarcoma.
PURPOSE: This randomized phase III trial is studying giving external-beam radiation therapy to a small area of tissue surrounding the tumor to see how well it works compared with giving external-beam radiation therapy to a wider area of tissue surrounding the tumor in treating patients who have undergone surgery for soft tissue sarcoma of the arms, hands, legs, or feet.
- Detailed Description
OBJECTIVES:
Primary
* Determine if reduced volume adjuvant radiotherapy increases limb function without compromising local control in patients with previously resected extremity soft tissue sarcoma.
Secondary
* Determine the toxicity of this regimen in these patients.
* Determine the overall level of disability in patients treated with this regimen.
* Determine the disease-free survival and overall survival of these patients.
OUTLINE: This is a randomized, controlled, prospective, multicenter study. Patients are stratified according to tumor grade (1 vs 2 vs 3), adequacy of surgical clearance (R0 vs R1), and treatment center. Patients are randomized to 1 of 2 treatment arms.
* Arm I (control): Patients undergo external beam radiotherapy (EBRT), including full margins, once daily 5 days a week for 6½ weeks .
* Arm II: Patients undergo EBRT as in arm I but only reduced margins are included.
After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

Group Intervention Description Research arm radiotherapy Radiotherapy Research arm A total of 33 fractions each of 2Gy should be given once a day for 5 days per week over 6 weeks and 3 days in week 7, totalling 66Gy. The 66Gy in 33 fractions will be delivered to CTV2 alone. No attempt will be made to include drain/biopsy sites or the surgical scar. Control arm radiotherapy Radiotherapy Conventional treatment arm A total of 33 fractions each of 2Gy should be given once a day for 5 days per week over 6 weeks and 3 days in week 7, totalling 66Gy. The first 50 Gy in 25 fractions will be given to CTV1 and subsequent 16 Gy in 8 fractions will be delivered to CTV2.
