The published studies have proven the informativeness and safety of standard techniques of sentinel lymph node biopsy after neoadjuvant treatment for cN0 patients. For group cN1 and regression of metastases after neoadjuvant treatment, standard sentinel lymph node biopsy techniques have failed. The use of combined methods of double detection and an increase in the number of examined lymph nodes to 3 and more increased the detection rate of sentinel node biopsy after neoadjuvant therapy and reduced false-negative rate. Long-term results, questions of methodology lymph nodes evaluation, radiation therapy in this group of patients require further investigation.</p></abstract><trans-abstract xml:lang="ru"><p>Закономерным следствием достижений системной предоперационной терапии рака молочной железы является деэскалация хирургического лечения. Все большее распространение  получают удаление и исследование ограниченного количества подмышечных лимфатических узлов (ЛУ) после неоадъювантной терапии и отказ от лимфаденэктомии при отсутствии метастатического поражения. Проведенные исследования доказали информативность и безопасность стандартных методик биопсии сигнальных ЛУ после неоадъювантного лечения при сN0. При cN1 и регрессе изменений в результате неоадъювантного лечения стандартные методики оценки состояния ЛУ оказались несостоятельны. Применение комбинированных методов двойной детекции и увеличение количества исследованных ЛУ до 3 и более повысили информативность методики и позволили снизить частоту ложноотрицательных результатов. Отдаленные результаты, вопросы методологии исследования ЛУ, лучевой терапии в этой группе пациентов требуют дальнейшего изучения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neoadjuvant therapy</kwd><kwd>breast cancer</kwd><kwd>sentinel lymph node biopsy</kwd><kwd>targeted lymph node dissection</kwd><kwd>axillary lymph node dissection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неоадъювантная терапия</kwd><kwd>рак молочной железы</kwd><kwd>биопсия сигнальных лимфатических узлов</kwd><kwd>таргетная лимфодиссекция</kwd><kwd>подмышечная лимфаденэктомия</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">Semiglazov V.F., Chagunava O.L.
