- The study analyzed the effectiveness of radiation therapy for 45 patients with uterine cervix cancer or maxillary sinus cancer treated from 2009-2013 at the Transcarpathian Regional Clinical Oncology Dispensary. - Patients who received topometric preparation using CT scans and 3D treatment planning with W PLAN 2000 had better clinical outcomes and fewer/less severe radiation complications compared to patients who received topometric preparation using anatomical atlases and isodose maps. - The use of advanced topometric preparation methods like CT scans and 3D planning allowed for more precise dose delivery and optimization, resulting in improved treatment effectiveness.

FUNCTION OF TOPOMETRIC PREPARATION IN MODERN PLANNING OF RADIATION THERAPY FOR
ONCOLOGIC PATIENTS
In the article is expounded the analyses of radiation therapy effectiveness – for the patients at radiation department of Transcarpathian Regional Clinical Oncologic dispensary, who received treatment concerning cervix of the
uterus cancer and maxillary sinus cancer – during the years of 2009-2013.
In comparison was taken the treatment effectiveness and heaviness of radiation complications within the group of
patients for whom the topometry preparation was held with the help of anatomotopometry atlases, isodos maps
and also group of patients for whom the topometry preparation was held with the help of KT-scanes and threedimensional planning system W PLAN 2000. With all the patients of the second group was registered reliably better clinical result of radiation therapy for the reason of lower quantity and heaviness of radiation complications at
the conditions of giving optimal therapeutic dose.
Key words: distance radiation therapy, topometry preparation, isodose division, radiation complications, cervix of
the uterus cancer, maxillary sinus cancer
