Fast neutron radiotherapy for soft tissue sarcomas. University of Washington experience and review of the world's literature.

Sixteen patients with inoperable soft tissue sarcomas were treated definitively with fast neutrons at the University of Washington between August, 1970 and May, 1982. Eleven of these 16 patients were treated with curative intent and form the basis of this report. Actuarial plots are shown for local tumor control and survival. This work is placed in the context of worldwide experience in using fast neutrons to treat unresectable soft tissue sarcomas.
