Soft Tissue Sarcomas Treated by Electron Beams

Soft tissue sarcomas are nonepithelial tumors arising from tissue other than bone (except for the reticuloendothelial system, subtentacular tissue of viscera and organs) and from the peripheral and sympathetic nervous system [7]. All sarcomas developed in viscera, Kaposi’s sarcoma, soft tissue metastases, and soft tissue tumors in children [5] are excluded from this study.
