[Fast neutrons 6.3 MeV in the combined treatment of patients with local recurrence of breast cancer].

The article is devoted to the problem of treatment of patients with locally advanced breast cancer recurrences as well as a study of neutron therapy influence on normal tissues and various critical organs. The use of fast neutrons of 6.3 MeV in these patients is often the only treatment option. A 6-year survival rate of patients without repeated signs of recurrent breast cancer after neutron and neutron-photon therapy is 92.2 ± 5.7%.
