В настоящее время отмечен повышенный интерес к изучению молекулярно-биологических характеристик циркулирующих опухолевых клеток. Недавние исследования показали наличие различных популяций циркулирующих опухолевых клеток в крови у онкологических больных. Часть клеток являются стволовыми опухолевыми клетками, часть опухолевых клеток находятся в состоянии emt (epithelial-mesenhimal transition), и большая часть циркулирующих опухолевых клеток не имеют признаков стволовости и emt. </p><p>Целью исследования явилась оценка пятилетней безметастатической выживаемости у больных с инвазивной карциномой молочной железы в зависимости от наличия различных популяций циркулирующих опухолевых клеток в крови до начала лечения. </p><sec><title>Материал и методы</title><p>Материал и методы. В проспективное исследование включено 47 больных с впервыедиагностированным инвазивным раком молочной железы t1–4N0–3m0 стадии, в возрасте от 31 до 69 лет, поступивших на лечение в НИИ онкологии, Томский НИМЦ. В крови больных до начала лечения с помощью меченных различными флюорохромами моноклональных антител к epcam, Сd45, cd44, cd24 и N-cadherin определяли наличие различных популяций ЦОК методом многоцветной проточной цитометрии на аппарате BdFacscanto. Пятилетнюю безметастатическую выживаемость оценивали методом Каплана–Мейера. Различия считались достоверными при уровне значимости р&lt;0,05.  </p></sec><sec><title>Результаты</title><p>Результаты. Полученные результаты показали, что наличие циркулирующих опухолевых клеток с признаками ЕМТ как стволовых, так и нестволовых с фенотипами  epcam+cd45-cd44-cd24-Ncadherin+, epcam+cd45-cd44+cd24-Ncadherin+ и epcam(м)-cd45-cd44+cd24-Ncadherin+ в крови у больных РМЖ до лечения снижает пятилетнюю безметастатическую выживаемость. </p></sec><sec><title>Заключение</title><p>Заключение. Таким образом, циркулирующие опухолевые клетки с признаками ЕМТ являются информативным объектом для жидкостной биопсии с целью оценки риска гематогенного метастазирования и могут рассматриваться как мишени для подбора персонифицированной химиотерапии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Localized and metastatic tumors are known to lead to the formation of circulating tumor cell (CTC ) clusters in the blood. Currently, there is a heightened interest in the study of molecular and biological characteristics of CTC s. Recent studies have shown the presence of different populations of CTC s in the blood of cancer patients. Some cells are cancer stem cells, some tumor cells undergo epithelial-mesenchymal transition (EMT), and most CTC s do not have features of either stem cells or EMT.</p><p>The aim of the study was to evaluate the five-year metastasis-free survival rate in patients with invasive breast carcinoma, depending on the presence of various populations of circulating tumor cells in the blood before treatment.</p><sec><title>Material and Methods</title><p>Material and Methods. A prospective study included 47 patients with newly diagnosed invasive breast cancer (T1–4N0–3M0), who were treated at Cancer Research Institute, Tomsk National Research Medical Center. The patients aged 31 to 69 years. The presence of different populations of CTC s in the blood of patients before treatment was determined by multicolor flow cytometry on the BD FACS Canto system, using different fluorochrome-labeled monoclonal antibodies to EpCam, CD 45, CD 44, CD 24, and N-cadherin. Five-year metastasis-free survival was evaluated by the Kaplan–Meier method. The differences were considered significant at p&lt;0.05.</p></sec><sec><title>Results</title><p>Results. The results obtained demonstrated that the presence of both stem-like and non-stem CTC s showing signs of EMT with Epcam+CD 45-CD 44-CD 24-Ncadherin+, Epcam+CD 45-CD 44+CD 24-Ncadherin+, and Epcam(m)- CD 45-CD 44+CD 24-Ncadherin+ phenotypes in the blood of breast cancer patients before  treatment reduced the five-year metastasis-free survival rate (p=0.0016, p=0.017 and p=0.011, respectively).</p></sec><sec><title>Conclusion</title><p>Conclusion. Thus, CTC s in the EMT state are informative for liquid biopsy to assess the risk of hematogenous metastasis and can be considered as targets for selection of personalized chemotherapy. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак молочной железы</kwd><kwd>гетерогенность ЦОК</kwd><kwd>пятилетняя безметастатическая выживаемость</kwd><kwd>циркулирующие стволовые опухолевые клетки</kwd><kwd>эпителиально-мезенхимальный переход</kwd><kwd>жидкостная биопсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>breast cancer</kwd><kwd>CTC heterogeneity</kwd><kwd>five-year metastasis-free survival</kwd><kwd>circulating cancer stem cells</kwd><kwd>epithelial-mesenchymal transition</kwd><kwd>liquid biopsy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта Президента РФ МД-544.2018, МД-2017.2020.7.</funding-statement><funding-statement xml:lang="en">The study was supported by the grant of the President of the Russian Federation MD-544.2018, MD-2017.2020.7.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Каприн А.Д., Старинский В.В., Петрова Г.В.
