Soft part tumors.

Results of management of rhabdomyosarcoma of childhood have improved in a dramatic manner during the recent 10 years as a consequence of the treatment by three modality approach which relies on an intensive multi-drug multicycle chemotherapy regimen combined with radiation therapy and or surgery. Both local results and total disease-free survival rates are markedly better with this more comprehensive approach. A staging system for sarcoma of soft tissue has just been developed by the A.J.C. Histopathological grade is the important parameter: stage 1,2, and 3 are tumors of histological grades 1, 2, and 3 respectively (an outline of the system is presented). Treatment results of 100 patients with sarcoma of soft tissue (extremities 89, torso 11) treated by radical dose radiation therapy (less than 6300 rad) and limited surgery at M.D. Anderson Hospital are presented. For both local control and disease free survival, results decreased with advancing stage and anatomic site was not a factor per se. Radiation therapy under tourniquet induced hypoxia was not found to be significantly more effective than conventional radical dose therapy. The necessity of planning treatment such that if subsequent surgery is required, the fields will provide the best distribution of unirradiated or low dose tissue for preparation of flaps, etc.
