Radical surgery is currently the best therapy.
In comparison with results of conventional irradiation, postoperative neutron treatment appears to be more effective. The objective was to increase the total administered dose and possibly improve local control, without increasing late normal tissue damage. Five patients received 62.5 Gy in 5 weeks pre-operatively and 3 palliatively. Nineteen of the remaining 21 patients received 75 Gy in 6 weeks with a field size reduction after 5 weeks. Sixteen of 29 tumours were situated in the thigh and only 2 were in the upper limb.
