В последние годы все большее внимание уделяется поиску маркеров, которые позволяют прогнозировать данный ответ опухоли на неоадъювантную химиотерапию (НАХТ).</p></sec><sec><title>Цель исследования</title><p>Цель исследования: оценка предсказательной значимости ряда молекулярных параметров (цитокератина 5/6, эпидермального фактора роста EGFR1 и маркера клеточной пролиферации Ki-67) у больных базальноподобным трипл-негативным раком молочной железы.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование было включено 44 больных базальноподобным трипл-негативным раком молочной железы, получивших 2–4 курса НАХТ по схемам FAC и CAX. У всех больных в биопсийном материале опухоли определялись рецептор- ный статус (РЭ, РП, Her-2/neu), уровень пролиферативной активности Ki-67, СК 5/6 и эпидермальный фактор роста EGFR1 (шкала Nielsen). Оценка эффективности НАХТ осуществлялась по шкале RECIST.</p></sec><sec><title>Результаты</title><p>Результаты. Наибольшее количество ПМР отмечено у больных с трипл-негативным РМЖ, в опухолевой ткани которых выявлена экспрессии только EGFR1 (69 %, р=0,01). К наиболее значимым характеристикам данного параметра относятся высокий уровень (72 %, р=0,02); умеренная или выраженная экспрессия (90 %, р=0,02). При этом лучший ответ отмечался при высокой пролиферативной активности опухолевых клеток (90 %, р=0,0006) и при использовании схемы САХ (81 %, р=0,004). Разработанная модель логистической регрессии позволяют прогнозировать частоту ПМР с высокими показателями чувствительности (82 %) и специфичности (67 %).</p></sec><sec><title>Выводы</title><p>Выводы. Полученные результаты позволяют рассматривать изученные маркеры в качестве предиктивных параметров, а разработанная модель логистической регрессии – оценивать ожидаемую эффективность в виде достижения ПМР и планировать лечение.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: Pathological complete response is a predictor of favorable clinical outcome in patients with tripl-negative breast cancer. Over the last years there was an increasing interest to the search for predictive markers of tumor response to neoadjuvant chemotherapy (NACH). The purpose of the study is to assess predictive markers: cytokeratin 5/6, epidermal growth factor receptor (EGF1) and proliferation marker Ki-67 in patients with basal-like tripl-negative breast cancer.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: The study included 44 patients with basal-like tripl-negative breast cancer, who received 2–4 courses of NACH with FAC and CAX regimens. Estrogen and progesterone receptors, Her-2/neu, the levels of proliferative activity of Ki-67, CK 5/6 and EGFR1 were determined in all breast cancer biopsies. Response to NACH was assessed using RECIST scale.</p></sec><sec><title>Results</title><p>Results. Pathological complete response was observed in 69 % of breast cancer patients, who had only EGFR1expression in tumor tissue (р=0.01). The best response was noted at high proliferative activity of tumor cells (90 %, р=0.0006) and when using CAX regimen (81 %, р=0.004). The model of logistic regression enables prediction of pathological complete response with high rates of sensitivity (82 %) and specificity (67 %).</p></sec><sec><title>Conclusion</title><p>Conclusion. The results obtained indicate that the studied markers can be used as predictors of clinical outcome and the devised model of logistic regression can be used to predict the chemotherapy response of breast cancer based on clinical pathological variables.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>неоадъювантная химиотерапия</kwd><kwd>предиктивные факторы прогноза</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>neoadjuvant chemotherapy</kwd><kwd>predictive markers</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Brouckaert O., Wildiers H., Floris G., Neven P.
