Parasternal lymphoscintigraphy in radiotherapy design in breast cancer

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)
