Results of the second phase of clinical testing of 6.3 MeV neutrons at the Kiev cyclotron U-120 in treatment of 498 patients

Results of the second phase of clinical testing of 6.3 MeV neutrons in the course of irradiation of 498 patients with tumours of different localizations and different depth under body irradiated surface at various stages of treatment are provided. Using soft tissue sarcomas by way of example, indices of 3-year survival rate of the patients and averaged morphometric data of hystostereological analysis are presented. The conclusion is made on clinical efficiency and advisability of continuation of the study to the thirst stage of testing of 6.3 MeV neutron beam for treating oncological patients
