The number of lymphogenic metastases in the axillary region is the most important predictor of parenchymal metastasis in breast cancer (BC). The proliferation index Ki67 (IP) in lymphogenic metastasis cells as a predictor of metastasis to parenchymal organs has not been studied enough to date. Patients and methods. Comparative analysis of IP in primary tumor cells and lymphogenic metastatic cells are done in 58 patients with luminal BC T1-4N1-3. Results. It was found that the discrepancy of IP (IPdis) in the cells of luminal BC and its lymphogenic metastases occurs in 82.8% of cases. It was found that lymphogenic metastases in the group of patients IP(-)dis higher than in patients IP(+)dis. However, the difference was not statistically significant. Much more detected significant IPdis. In 5 cases, a higher IP in lymphogenic metastatic cells may be the cause of diagnosis of aggressive luminal B molecular subtype of BC, followed by prediction of a higher risk of parenchymal metastasis. Conclusions. The results of comparative analysis of IP in primary tumor cells and lymphogenic metastatic cells in patients with luminal BC N1-3 in the long term can be used as a predictor of high metastatic potential and as a consequence of a short period of relapse-free survival.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Количество лимфогенных метастазов аксиллярной области - важнейший фактор прогноза при карциноме молочной железы (КМЖ). Значение показателя пролиферативной активности КМЖ, определяемого по иммуногистохимической экспрессии маркера Ki67 в клетках лимфогенного метастаза как предиктора отдаленного метастазирования изучено недостаточно. Цель исследования. Провести сопоставление показателей пролиферативной активности, определяемой по индексу Ki67, в клетках первичной люминальной КМЖ (58 пациентов) и ее лимфогенных метастазах аксиллярной зоны. Результаты. В 82,8% наблюдений выявлен диссонанс пролиферативной активности индекса пролиферации Ki67 (md/s) КМЖ и ее лимфогенных метастазов. В 41,4% случаев пролиферативная активность опухолевой ткани метастатического лимфоузла превосходила таковую в первичной карциноме, при этом в 31% она была выше на 5% и более. Установлено, что число (медиана) лимфогенных метастазов в группе пациентов ИП(-)С/5 выше, чем у пациентов ИП(+)С/5. Однако разница оказалась статистически недостоверной. В пяти наблюдениях КМЖ со значительным ИП(-)С/э вариантом, в которых по данным ИПоп был диагностирован люминальный А подтип опухоли, высокий показатель ИП в клетках лимфогенного метастаза стал основанием для верификации более агрессивного люминального В подтипа КМЖ. Выводы. Методика сопоставления ИП в клетках первичной КМЖ и ее лимфогенных метастазах в перспективе может быть использована для уточнения морфологического подтипа опухоли, коррекции лечения и прогнозирования выживаемости при КМЖ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>luminal breast cancer</kwd><kwd>lymphogenic metastases</kwd><kwd>parenchymal metastasis</kwd><kwd>Ki67 proliferation index</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>люминальная карцинома молочной железы</kwd><kwd>лимфогенный метастаз</kwd><kwd>отдаленное метастазирование</kwd><kwd>паренхиматозное метастазирование</kwd><kwd>пролиферативная активность</kwd><kwd>индекс пролиферации Ki67</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Гуров А.Н., Балканов А.С., Катунцева Н.А., Огнева Е.Ю.
