Prise en charge des sarcomes des tissus mous des membres par radiothérapie externe

Soft tissue sarcomas are rare tumours. Conservative surgery followed by postoperative radiation therapy represents the gold standard in the majority of cases. Postoperative radiotherapy improves local control without affecting survival. Besides the quality of surgical excision, which remains the major prognostic factor, the importance of the irradiation volume and particularly margins used in external beam radiotherapy were also found to influence local control of the disease. In this study, we propose to conduct a literature review on the present state of our knowledge on this subject in the form of an articulated controversy: in favour or opposed to large margins in external radiotherapy.
