Surgical versus radiotherapeutic margins in the treatment of soft tissue sarcoma of the extremities Schematic description of margins used in the therapy of ESTS. Margins used for radiotherapy differ from those used in surgical resection of the tumour. Nevertheless both include an extra rim of healthy tissue as an attempt to include all microscopic disease around the vast tumour. CC = Cranio-caudal, CTV = clinical target volume, GTV = gross tumour volume, LM = Latero-medial, RT = Radiotherapy
