Efficacy of neutron and neutron-photon therapy in complex treatment of breast cancer local recurrence

The efficacy of neutron and neutron-photon therapies in the complex treatment of 88 patients with T2-4N0-2M0 breast cancer local recurrence was studied. Complete regression of recurrent tumor was observed in 100 % of patients who received neutron therapy, in 93 % of patients who received neutron-photon therapy and in 61 % of patients after electron therapy (control group). The 5-year survival rate for patients who underwent neutron and neutron-photon therapy was significantly higher than that of the control group (91,7 ± 6,2 % versus 51,5 ± 9,1 %, p=0,0001). The overall 5-year survival rate was 80,3 ± 9,2 % for patients treated with neutron and neutron-photon therapies concurrent with adjuvant chemotherapy according to CAF regimen and 56,8 ± 9,4 % for the control group (p
