The tumor structure in breast cancer is characterized not only by morphological heterogeneity of tumor cells, but also by a high degree of heterogeneity of tumor microenvironment, which contains immune cells, cell matrix elements, and other components that may have procarcinogenic or anticarcinogenic effects. Therefore, personalized approaches to selecting the most effective breast cancer treatment protocols cannot be used without comprehensive analysis of the target cancer markers and cellular microenvironment biomarkers.</p><p>This review is aimed at systematizing the data on tumor microenvironment biomarkers and evaluating the prognostic value of the analysis of tumor microenvironment biomarkers in breast cancer.</p><p>Biomarkers of the tumor microenvironment are important prognostic factors. Molecular genetic analysis of the profile of these biomarkers, as well as immunohistochemical studies of the mutual arrangement of tumor cells and tumor microenvironment can be used for high-accuracy cancer diagnosis and for the selection of effective personalized therapy in breast cancer. This comprehensive research is necessary because of the plasticity of tumor microenvironment cells, which can either support tumor growth, block immune response, and provide resistance to drugs, or exhibit antitumor activity.</p><p>The key elements of the tumor microenvironment in breast cancer have been analyzed, and examples of interaction between tumor cells and the microenvironment, as well as data on the prognostic and diagnostic values of tumor microenvironment biomarkers, have been summarized. The tumor microenvironment has been shown to affect the formation of drug resistance and the efficiencies of various breast cancer therapies.</p></abstract><trans-abstract xml:lang="ru"><p>Рак молочной железы является наиболее частой нозологией в структуре женской онкологической заболеваемости. Опухолевая структура при раке молочной железы характеризуется не только морфологической гетерогенностью опухолевых клеток, но и высокой степенью гетерогенности опухолевого микроокружения, включающего клетки иммунной системы, элементы клеточного матрикса и другие компоненты, которые могут оказывать проонкогенное и противоонкогенное действие. Таким образом, применение персонализированных подходов для выбора наиболее эффективных протоколов терапии рака молочной железы невозможно без комплексного исследования целевых онкомаркеров и биомаркеров клеточного микроокружения.</p><p>Цель работы – систематизировать данные о биомаркерах опухолевого микроокружения и провести оценку прогностической ценности исследования биомаркеров опухолевого микроокружения при раке молочной железы. Биомаркеры опухолевого микроокружения являются важным прогностическим фактором. Молекулярно-генетический анализ профиля таких биомаркеров, а также иммуногистохимические исследования взаимного расположения клеток опухоли и опухолевого микроокружения могут использоваться для высокоточной онкодиагностики и для подбора эффективной персонализированной терапии при раке молочной железы. Необходимость такого широкого комплексного исследования определяется пластичностью клеток микроокружения опухоли, которые могут как поддерживать опухолевый рост, блокировать иммунный ответ и обеспечивать резистентность к лекарственным препаратам, так и проявлять противоопухолевую активность.</p><p>В настоящем обзоре проанализированы ключевые элементы микроокружения опухоли, встречающиеся при раке молочной железы, примеры взаимодействия опухолевых клеток с микроокружением, данные прогностической и диагностической ценности биомаркеров микроокружения опухоли. Показано, что микроокружение опухоли влияет на образование лекарственной устойчивости и эффективность различных методов терапии рака молочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>tumor microenvironment</kwd><kwd>biomarkers</kwd><kwd>detection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>микроокружение опухоли</kwd><kwd>биомаркеры</kwd><kwd>детекция</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation through the grant No. 075-15-2021- 937 (NanoToBio project)</funding-statement><funding-statement xml:lang="ru">Данная работа была поддержана грантом № 075-15-2021-937 (проект NanoToBio) Министерства науки и высшего образования Российской Федерации.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sung H., Ferlay J., Siegel R.L. et al.
