Triple negative breast cancer has no specific treatment sites for chemotherapy and is unfavorable in terms of prognosis. One of the drugs widely used in this cohort of patients is eribulin, which in addition to its antimitotic effect has an effect on the tumor microenvironment. The search for biological criteria that will allow predicting the effectiveness of the drug is assumed relevant since it will help to select patients who may receive the most benefit from certain therapy regimens.</p><p><bold>Objective</bold>: identification of immunological predictors of the therapeutic effectiveness of eribulin in patients with locally advanced or metastatic triple-negative breast cancer.</p><p><bold>Materials and methods</bold>. The study included 20 patients with locally advanced and metastatic triple negative breast cancer. 50 % had a short-term response (progression-free survival &lt;3 months) to eribulin therapy, and 50 % had a long-term response (progression-free survival &gt;6 months). Seven-color immunofluorescence was used to determine the subpopulation composition of tumor-infiltrating lymphocytes and their PD1 expression. Image acquisition and analysis were performed using the Vectra® 3.0 system and InForm® software (Akoya Biosciences, USA).</p><p><bold>Results</bold>. It has been shown that the ratio of the number of PD1-negative to PD1-positive CD20+ B-lymphocytes less than 5.5 associated with the long-term effectiveness of eribulin in patients with locally advanced or metastatic triple negative breast cancer.</p><p><bold>Conclusion</bold>. The results showed that the ratio of the number of PD1-negative to PD1-positive CD20+ B-lymphocytes can be considered as a possible marker to predict the effectiveness of eribulin in patients with breast cancer.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. трижды негативный рак молочной железы не имеет специфических точек приложения для химиотерапии и неблагоприятен по прогнозу течения. Одним из препаратов, широко применяемых у данной когорты больных, является эрибулин, обладающий, помимо антимитотического действия, влиянием на микроокружение опухоли. актуальным представляется поиск биологических критериев, которые позволят предсказать эффективность препарата, что позволило бы отбирать пациентов, которым могут быть наиболее полезны определенные схемы терапии.</p><p><bold>Цель исследования</bold> – выявить иммунологические предикторы терапевтической эффективности применения эрибулина у пациентов с местно-распространенным или метастатическим трижды негативным раком молочной железы. Материалы и методы.  В исследование были включены 20 больных местно-распространенным и метастатическим трижды негативным раком молочной железы, у 50 % наблюдался короткий ответ (выживаемость без прогрессирования &lt;3 мес) на терапию эрибулином, а у 50 % – длительный (выживаемость без прогрессирования &gt;6 мес). мультиплексная иммунофлуоресценция была использована для определения субпопуляционного состава опухоль-инфильтрирующих лимфоцитов и экспрессии ими PD1. Получение и анализ изображений были проведены с помощью системы Vectra® 3.0 и программного обеспечения InForm® (Akoya Biosciences, США).</p><p><bold>Результаты</bold>. Показано, что отношение количества PD1-отрицательных к количеству PD1-положительных CD20+ В-лимфоцитов &lt;5,5 ассоциировано с длительной эффективностью применения эрибулина у пациентов с местно-распространенным или метастатическим трижды негативным раком молочной железы.</p><p><bold>Заключение</bold>. соотношение количества PD1-отрицательных и PD1-положительных  CD20+ B-лимфоцитов  можно рассматривать как возможный маркер для прогнозирования эффективности эрибулина у пациентов с местно-распространенным или метастатическим трижды негативным раком молочной железы.</p></trans-abstract><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>eribulin</kwd><kwd>tumor microenvironment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>эрибулин</kwd><kwd>опухолевое микроокружение</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The article was published with the financial support of Eisai Co., Ltd.
