METHOD FOR TREATING LOCAL RELAPSES OF MAMMARY CANCER Russian patent published in 2006 - IPC A61N5/10 

FIELD: medicine, oncology.

SUBSTANCE: one should carry out radiation therapy with quick neutrons 6.3 Mev twice weekly in two stages: at the first stage it is necessary to prescribe 3-4 seances of neutron therapy at interval of 48-72 h directly onto area of tumoral relapse and onto surrounding normal tissues at the distance of about 3-5 cm against tumoral foci, single focal dosage being 1.6-2.0 Gy, relative biological efficiency corresponds to 2.91-2.79, onto the skin - 2.0-2.2 Gy, up to total focal dosage being 6.6±1.5 Gy, onto the skin - 8.3±1.3 Gy, at the second stage it is necessary to carry out gamma- or electronic therapy at single focal dosage being 2.0-3.0 Gy, 5 fractions weekly, moreover, total course dosage of neutron-photon irradiation per a focus corresponds to 60 Gy by isoeffect at duration of irradiation course of about 20-25 d.

EFFECT: higher efficiency of therapy.
