简要总结
This trial aims to assess the long-term efficacy of moderately hypofractionated neoadjuvant radiotherapy for soft tissue sarcoma in the limbs or trunk wall. The primary outcome is local disease control, assessed by the cumulative incidence of progression/recurrence.
After informed consent has been obtained and eligibility criteria have been checked, a baseline assessment will be performed followed by the experimental treatment: intensity-modulated radiotherapy with a moderately hypofractionated regimen consisting in 15 fractions of 2.7 Gy administered over 3 weeks.
a follow-up assessment will be performed 3 to 4 weeks after the last radiotherapy session.
Tumor resection will be performed 4 to 8 weeks after the radiotherapy. Patients will then be followed up until the end of the study; planned 5 years after the last inclusion.
Radiotherapy will be evaluated in terms of safety and efficacy.
详细描述
The NEORASARC clinical trial aims to assess the long-term efficacy of moderately hypofractionated neoadjuvant radiotherapy for soft tissue sarcoma in the limbs or trunk wall.
After informed consent has been obtained and eligibility criteria have been checked, a baseline assessment will be performed 8 weeks prior to the start of experimental treatment. This baseline assessment will consist in of a clinical examination, an MRI scan, and the completion of the MSTS and QLQ-C30 questionnaires. After a blood sample has been taken for translational research, the patient will receive the experimental treatment : intensity-modulated radiotherapy delivered in a moderately hypofractionated scheme consisting in 15 fractions of 2.7 Gy over 3 weeks. The total prescribed dose will be 40.5 Gy.
3 to 4 weeks after the last radiotherapy session, patients will undergo an MRI scan.
Tumor resection will be performed 4 to 8 weeks after the radiotherapy. A blood sample will be taken prior to this surgery for translational research.
Patients will then be followed up every 4 months for the first 2 years, every 6 months for 3 years and then annually until the end of the study. At each follow up, a clinical examination, an MRI scan and the completion of the MSTS and QLQ-C30/F17 questionnaires will be performed.
