Data on 200 patients aged 30 to 65 years with primary BC (Stages IIB-IIIA), who had been treated at the Rostov Cancer Research Institute in 2006 to 2009, served as a material for the study. The levels of steroid hormones of the estrogenic, androgenic, and glucocorticoid series were studied before and after neoadjuvant CT.<bold>Results</bold>. When neoadjuvant poly-CT (PCT) was performed on automedia, the levels of total estrogens were almost unchanged; the frac- tions of estrone and estriol also remained stable. Only estradiol levels were recorded to show a certain declining tendency.There were considerable changes in the expression of all steroid hormones during preoperative systemic PCT.According o the drug therapy option, significant differences were found in the time course of changes in blood cortisol levels. <bold>Conclusion</bold>. Neoadjuvant CT on automedia results in diminished estrogenization irrespective of age and the phase of the menstrual cycle.</p></abstract><trans-abstract xml:lang="ru"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>neoadjuvant chemotherapy</kwd><kwd>levels</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>неоадъювантная химиотерапия</kwd><kwd>уровни гармонов</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
