At the Scientific and Research Department of Radiation Oncology of the National Cancer Institute since 2001 have been conducted scientific trials. 183 patients have been treated during mentioned period. These patients were stratified to 3 groups. First group (95 patients) received radiotherapy on the Rokus AM and the Teratron. The second group (57 patients) received radiotherapy on the electron linear accelerator Mevatron KD2. The third group (31 patients) received radiotherapy on the electron linear accelerator Clinac 2100. Patients in third group, underwent the precise geometric 3D planning with further planning of the radiation fields. Analysis of the study results revealed the lower percentage of manifestations of the radiation side reactions and better response in the third group in the consequences of use the three-dimensional planning, summing up of the lower doses to the critical organs and tissues through the use of laser devices, locking devices, multileaf collimator and the wedge-shaped filters that allowed more precisely and accurately treat patients.
