Рак яичников (РЯ) является одним из самых агрессивных и тяжело поддающихся лечению онкологических заболеваний. Около 75% случаев РЯ выявляется на поздних стадиях заболевания. Асцитическая жидкость является перспективным биологическим материалом для получения информации о характере опухолевого процесса при РЯ. Перитонеальная диссеминация считается одним из наиболее неблагоприятных факторов прогрессирования злокачественных опухолей. Однако прогностические факторы, связанные со злокачественным асцитом, изучены недостаточно.</p><p>Целью данного исследования явилась оценка различных популяций опухолевых клеток в асцитической жидкости больных РЯ методом многоцветной проточной лазерной цитометрии на основе молекулярной панели маркеров EpCam, СD45, CD44, CD24, CD133 и N-cadherin. В проспективное исследование включены 16 больных с впервые диагностированным РЯ, стадии Ic–IV по системе FIGO, возраст 36–76 лет, поступившие на лечение в НИИ онкологии Томского НИМЦ.</p><p>Материалом для исследования служила асцитическая жидкость, стабилизированная ЭДТА, взятая во время лапароскопии. Различные популяции асцитических опухолевых клеток (с признаками стволовости, с признаком ЕМТ (epithelial-mesenchymal transition), без признаков стволовости и ЕМТ, с сочетанием этих признаков, а также атипичные / гибридные популяции клеток определяли методом многоцветной проточной лазерной цитометрии на аппарате BDFACSCanto (США) с помощью меченных различными флуорохромами моноклональных антител к EpCam, СD45, CD44, CD24, CD133 и N-cadherin и программного обеспечения BD FACSDiva.</p><p>В результате исследования в асцитической жидкости больных РЯ было выявлено 12 популяций Ерcam-положительных клеток. Клеточный состав асцитической жидкости больных РЯ представляет собой гетерогенную популяцию. Большую концентрацию асцитических опухолевых клеток представляют собой атипичные / гибридные формы опухолевых клеток с признаком стволовости, а также стволовые опухолевые клетки Epcam+CD45-CD44+CD24+CD133+/- как с признаком ЕМТ, так и без него. </p></abstract><trans-abstract xml:lang="en"><p>Ovarian cancer is one of the most aggressive and hard-to-treat cancers. About 75% of ovarian cancer cases are detected at later stages of the disease. Ascitic fluid is promising biological material to get information about the tumor nature in ovarian cancer. Peritoneal dissemination is one of the most unfavorable factors of malignant tumor progression. However, prognostic factors associated with malignant ascites are not well understood.</p><p>The aim of the study was to evaluate various tumor cell populations in ascitic fluid of ovarian cancer patients by laser multicolor flow cytometry using a molecular panel of EpCam, CD45, CD44, CD24, CD133, and N-cadherin markers. The prospective study included 16 patients aged 36 to 76 years with newly diagnosed FIGO stage Ic–IV ovarian cancer, who were admitted for treatment to the CancerResearch Institute of Tomsk National Research Medical Center. </p><p>The study material included EDTAstabilized ascitic fluid sampled during laparoscopy. Various populations of ascitic tumor cells (with stemness features, with epithelial mesenchymal transition (EMT) features, without stemness and EMT features, with a combination of these features, as well as atypical / hybrid cell populations) were identified by multicolor flow cytometry on a BDFACSCanto apparatus (USA) using fluorochrome-labeled EpCam, CD45, CD44, CD24, CD133, and N-cadherin monoclonal antibodies and the BD FACSDiva software. The study revealed twelve populations of Epcam-positive cells in ascitic fluid of ovarian cancer patients. The cell composition of ascitic fluid in ovarian cancer patients is represented by a heterogeneous population. A large fraction of ascitic tumor cells are atypical / hybrid tumor cells with stemness features as well as Epcam+CD45–CD44+CD24+CD133+/-cancer stem cells, both with and without EMT features. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичников</kwd><kwd>асцитические опухолевые клетки</kwd><kwd>стволовые опухолевые клетки</kwd><kwd>многоцветная проточная цитометрия</kwd><kwd>жидкостная биопсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>ascitic tumor cells</kwd><kwd>cancer stem cells</kwd><kwd>multicolor flow cytometry</kwd><kwd>liquid biopsy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность руководителю отделения патологической анатомии и цитологии НИИ онкологии Томского НИМЦ проф.
