RESUMEN
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.

An evaluation of combined photon-neutron radiotherapy (CPNT) of malignant tumors of the salivary gland (31) is presented. Overall 1-year survival was 100%, 2 years--95%, 3 years--65%, 4 years--57% and 5 years--47%. Radiation-related injury incidence did not vary dramatically: CPNT--15%, photon therapy--11%. Most relapse occurred within the first 24 months.
