[Role of fast neutrons in the treatment of soft tissue sarcoma]

The report deals with our data on evaluation of combined photon-neutron radiotherapy (CPNT) received by 33 patients with soft tissue sarcoma at the Clinic of the Urals Neutron Therapy Center. Follow-up ranged 10-80 months (median--68 months). Complete response was reported in 100% (control--45%). All the patients survived 12 months after treatment (control--85%); 5-year survival was 42 and 22%, respectively. Our modality appeared to be the only means of ionizing radiation dose dispensation in cases of early relapse after photon therapy when there was a glimmer of hope of stabilization.
