In the Russian Federation, breast cancer (breast cancer) occupies a leading position in the structure of morbidity and mortality of female oncological diseases. Many retrospective studies have reported changes in the expression of bio-markers in surgical samples after neoadjuvant therapy. The study of changes in biological subtypes can change approaches to therapy and contribute to an increase in survival rates in such patients. Based on these data, we can talk about the need for repeated assessments of the tumor biotype during treatment, which contributes to an optimal and personalized approach to breast cancer therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Представлен обзор литературы, затрагивающей вопрос изменения фенотипа рака молочной железы (РМЖ) в процессе лечения. В Российской Федерации РМЖ занимает лидирующие позиции в структуре заболеваемости и смертности женских онкологических заболеваний. Во многих ретроспективных исследованиях сообщалось об изменении экспрессии биомаркеров в хирургических образцах после проведенной неоадъювантной терапии. Изучение изменения биологических подтипов способно изменить подходы к терапии и способствовать увеличению показателей выживаемости у таких пациенток. На основании приведенных данных можно говорить о необходимости проведения повторных оценок биотипа опухоли в процессе лечения, что способствует оптимальному и персонифицированному подходу к терапии РМЖ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>phenotype</kwd><kwd>molecular biological subtype</kwd><kwd>biotype transformation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>фенотип</kwd><kwd>молекулярно-биологический подтип</kwd><kwd>трансформация биотипа</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">Tamrazov R.I., Gaisina E.A., Tsarev O.N. et al.
