Канцероматоз брюшины является одним из наиболее неблагоприятных факторов прогрессирования рака яичников. Он часто сопровождается накоплением жидкости в брюшной полости – асцитом. Прогностические факторы, связанные со злокачественным асцитом, изучены недостаточно.</p></sec><sec><title>Цель</title><p>Цель. Оценка различных популяций EpСam-положительных опухолевых клеток в асцитической жидкости, их связь с наличием перитонеальных «инвазивных» имплантатов и  степенью распространенности канцероматоза по шкале  Predictive Index Value (PIV) у больных раком яичников.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В проспективное исследование  включены 22 больных с впервые диагностированным раком  яичников, с Ic–IV стадиями по системе FIGO, в  возрасте 36–76 лет, поступившие на лечение в НИИ онкологии Томского НИМЦ. Материалом для исследования  служила асцитическая жидкость, стабилизированная ЭДТА,  взятая во время лапароскопии. Количество различных  популяций опухолевых клеток в асцитической жидкости определяли методом многоцветной проточной цитометрии  и проточной цитометрии с визуализацией. Степень  канцероматоза определяли по шкале PIV.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что клеточный состав асцитической  жидкости больных раком яичников представляет собой  гетерогенную популяцию. Положительная корреляционная  связь с PIV, характеризующим степень распространенности  канцероматоза, наблюдалась у асцитических клеток с  фенотипом EpCam+CD45-CD44-CD24+CD133-Ncadherin+ (r = 0,58; p = 0,004) и у атипичных/гибридных форм клеток EpCam+CD45+CD44+CD24+/-CD133+/-Ncadherin+/- (r = = 0,51; р = 0,01).</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты показывают большую гетерогенность опухолевых клеток в асцитической жидкости больных раком яичников. Обнаруженный факт наличия  атипичных (гибридных форм) EpCam-положительных клеток  представляет интерес для клеточной биологии и  требует дальнейших исследований.  </p></sec></abstract><trans-abstract xml:lang="en"><sec><title> Background</title><p> Background. Peritoneal carcinomatosis (PC) is one of the most unfavorable factors of ovarian cancer progression. It is often accompanied by accumulation of fluid in the abdominal cavity, which is called ascites. However, prognostic factors associated with malignant ascites are not well understood.</p><p>The aim of this study was to evaluate dissimilar populations of EpCAM-positive cells in ascitic fluid and their relationship with the presence of invasive peritoneal implants and the prevalence of carcinomatosis on the Predictive Index Value (PIV) scale in ovarian cancer patients.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The prospective study included 22 patients aged 36–76 years with newly diagnosed FIGO stage Ic–IV ovarian cancer, who were admitted for treatment to Cancer Research Institute of Tomsk NRMC. The study material included EDTA-stabilized ascitic fluid sampled during laparoscopy. Various populations of ascites tumor cells were identified by laser multicolor flow cytometry. The degree of carcinomatosis was determined according to the PIV scale.</p></sec><sec><title>Results</title><p>Results. The study identified twelve populations of EpCAM-positive cells in the ascitic fluid of ovarian cancer patients. Epcam+CD45-CD44-CD24+CD133-Ncadherin+ cells (r = 0.58; p = 0.004) and atypical (hybrid) EpCam+CD45+CD44+CD24+/-CD133+/-Ncadherin+/- cells (r = = 0.51; р = 0.01) had a positive correlation with the PIV index.</p></sec><sec><title>Conclusion</title><p>Conclusion. The obtained results show a high degree of heterogeneity of tumor cells in the ascitic fluid of ovarian cancer patients. Identified atypical (hybrid) forms of EpCam-positive cells are of great interest for cell biology and require further investigation. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>гетерогенность опухолевых клеток</kwd><kwd>канцероматоз</kwd><kwd>Predictive Index Value</kwd><kwd>асцитическая жидкость</kwd><kwd>рак яичников</kwd><kwd>жидкостная биопсия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heterogeneity of tumor cells</kwd><kwd>carcinomatosis</kwd><kwd>Predictive Index Value (PIV)</kwd><kwd>ascitic fluid</kwd><kwd>ovarian cancer</kwd><kwd>liquid biopsy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Президента РФ (грант № МД-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">Виллерт А.Б., Коломиец Л.А., Юнусова Н.В., Иванова А.А.
