METHOD FOR APPLYING PHOTON-CAPTURING TUMOR THERAPY

摘要

FIELD: medicine. ^ SUBSTANCE: method involves introducing means containing heavy elements into tumor and expose it to X-ray radiation. A heavy chemical element having number of 53, 55-83 is used. The means contains one or several of said elements with additional ligand introduced as iminodiacetic acid or its derivatives or crownethers or porphyrins and a water-soluble polymer. The means is introduced in systemic or direct way into tumor with following X-ray irradiation of power of 10-200 keV being applied. ^ EFFECT: increased photon therapy dose concentrated in tumor tissue with concurrently reduced radiation exposure upon the unaffected tissues. ^ 4 cl, 4 dwg, 6 tbl
