Материал и методы. В клиническое исследование Nct04817501 включены 48 больных с впервые диагностированными новообразованиями яичников, из которых 42 пациентки с впервые диагностированным раком яичников Ic–IV стадии по FIGO, а также 6 женщин с пограничными новообразованиями яичников (ПОЯ), в возрасте от 36 до 76 лет. Материалом для исследования служили образцы асцитической жидкости и венозной стабилизированной крови. Наличие атипичных/гибридных форм EpCAM+CD45+ клеток в асцитической жидкости определяли методом многоцветной проточной цитометрии. Уровень онкомаркеров СА125 и He4 в сыворотке крови определяли методом ИФА. Результаты. Количество EPCAM+CD45+ клеток в асцитической жидкости больных серозной карциномой яичников составило 1,02 (0,30; 2,68) клеток/мкл, при этом в группе больных Low-grade серозной карциномы яичников (LGSC) их уровень составил 0,55 (0,03; 4,51) клеток/мкл, а в группе High-grade (HGSC) – 1,36 (0,41; 2,68) клеток/мкл. Показано, что количество EpCAM+CD45+ клеток в асцитической жидкости у больных с новообразованиями яичников имеет прямую корреляционную связь с уровнем CA125 и HE4 в сыворотке крови (R=0,60; р&lt;0,01 и R=0,34; р=0,05 соответственно). В группе LGSC между количеством EpCAM+CD45+ клеток в асцитической жидкости и уровнем онкомаркеров СА125 и He4 в крови наблюдается сильная прямая корреляционная связь (R=0,93; р&lt;0,01 и R=0,68; p=0,03 соответственно). Различий в количествах EpCAM+CD45+ клеток в асцитической жидкости и онкомаркеров СА125, HE4 в сыворотке крови у пациенток с HGSC и LGSC серозной карциномой яичников выявлено не было. У больных с ПОЯ наблюдается значимое снижение концентрации атипичных/гибридных форм клеток в асцитической жидкости и СА125, HE4 в сыворотке крови по сравнению с серозными карциномами яичников (р=0,02; p&lt;0,01; p&lt;0,01 соответственно). Заключение. Количество EpCAM+CD45+ клеток в асцитической жидкости пациенток связано с концентрациями СА125 и HE4 в крови у больных серозными карциномами яичников и не отличается от таких показателей у больных HGSC и LGSC.</p></abstract><trans-abstract xml:lang="en"><p>Purpose of the study: to assess the relationship between atypical/hybrid forms of EpCAM+CD45+ cells in ascitic fluid of ovarian cancer patients and the levels of cancer markers, such as CA125 and HE4, and the tumor grade. Material and methods. The study included 48 patients with newly  diagnosed ovarian cancer (42 patients with stage Ic–IV ovarian cancer and 6 patients with borderline ovarian tumors (Bots). The age of the patients ranged from 36 to 76 years. the study material included ascitic fluid and blood samples. the presence of atypical/hybrid forms of EpCAM+CD45+ cells in ascitic fluid was identified by laser multicolor flow cytometry. The levels of CA125 and HE4 markers were measured by ELISA. Results. The number of EpCAM+CD45+ cells in ascitic fluid of patients with serous ovarian carcinoma was 1.02 (0.30; 2.68) cells/µl (0.55 (0.03; 4.51) cells/µl in patients with low-grade serous carcinoma (LGSC) and 1.36 (0.41; 2.68) cells/µl in patients with high-grade serous carcinoma (HGSC). The number of EpCAM+CD45+ cells in ascitic fluid of serous ovarian carcinoma was shown to have a strong  correlation with СА125 and HE4 levels in blood serum (R=0.60; р&lt;0.01 and R=0.34; р=0.05, respectively). In the LGSC group, there was a strong direct  correlation between the number of EpCAM+CD45+ cells in ascitic fluid and the levels of CA125 and HE4 markers in blood serum (R=0.93; p&lt;0.01 and R=0.68; p=0.03, respectively). No differences in the levels of EpCAM+CD45+ cells in ascitic fluid and CA125/ HE4 markers in blood serum between patients with HGSC and LGSC were found. the levels of atypical/hybrid forms of cells in ascitic fluid and CA125/ HE4 markers in blood serum were  significantly lower in patients with Bots than in patients with serous ovarian carcinoma (p=0.02 for EpCAM+CD45+ cells and p&lt;0.01 for СА125/ HE4 levels). Conclusion. The relationship between the number of EpCAM+CD45+ cells in ascitic fluid and the levels of CA125 and HE4 markers in blood serum of patients with serous ovarian carcinoma was found. However, no differences in the levels of EpCAM+CD45+ cells in ascitic fluid and CA125/ HE4 markersin blood serum between patients with HGSC and LGSC were observed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичников</kwd><kwd>асцитическая жидкость</kwd><kwd>атипичные/гибридные формы опухолевых клеток</kwd><kwd>EpCAM+CD45+ клетки</kwd><kwd>CA125</kwd><kwd>HE4</kwd><kwd>HGSC</kwd><kwd>LGSC</kwd><kwd>пограничные опухоли яичников</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>ascitic fluid</kwd><kwd>atypical/hybrid cell forms</kwd><kwd>EPCAM+CD45+ cells</kwd><kwd>CA125</kwd><kwd>HE4</kwd><kwd>HGSC</kwd><kwd>LGSC</kwd><kwd>borderline ovarian tumors</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование выполнено при финансовой поддержке гранта Президента РФ МД-2017.2020.7.</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was supported by a grant from the President of the Russian Federation 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">Penet M.F., Krishnamachary B., Wildes F.B., Mironchik Y., Hung C.F., Wu T.C., Bhujwallan Z.M.
