RESUMO
Altogether 82 breast cancer patients were investigated to determine a possibility of the use of parasternal lymphoscintigraphy with colloid finely divided radiopharmaceuticals 99mTc and 198Au to form individual irradiation fields; 43 patients with fibroadenomatosis were taken as controls. Variants of the localization of parasternal lymph nodes were defined, standard and "optimum" (individual) parasternal irradiation field values were compared. 54.9% of the patients were shown to be in need of correction by increasing a standard irradiation field (5 cm wide).

The comparison of results of axillary lymphoscintigraphy with those of morphological examination of surgically removed lymph nodes in 78 patients with breast cancer showed overall reliability of the method to be 0.72, specificity--0.56 and sensitivity--0.92. Data of lymphoscintigraphy performed in 82 breast cancer patients to form fields of parasternal lymph node irradiation suggested enlarging standard field by 4 cm in 90.2% of cases and by 5 cm--in 54.9%.
