The recurrence developed in 19 patients (group 1), in 63 the recurrence was not diagnosed (group 2). Data prior to surgery (clinical characteristics, level CA-125), during surgery (cytokine concentration in peritoneal fluid, immunohistochemical analysis in capsule of ovarian endometriomas), postoperative therapy were evaluated as risk factors for recurrence. The Mann-Whitney U-test, the Fisher exact test was used to compare the groups. Specificity, sensitivity, accuracy, AUC ROC and threshold values were calculated.</p></sec><sec><title>Results</title><p>Results. The recurrence rate of ovarian endometriomas was 23%. There were no differences between groups according to age, proportion of smokers, body mass index, gynecological anamnesis, obstetric status and postoperative hormone therapy. Preoperative concentrations of CA-125 in group 1 were higher than in group 2: 62.5 U/ml [40.7; 112.3] vs 40.3 U/ml [20.3; 68.8], р &lt; 0.05. The concentration of IL-6, IL-8, TNFα, IL-1β, IL-17, VEGF, MCP 1 in peritoneal fluid taken during surgery was statistically significantly higher in group 1. The highest AUC ROC was received for VEGF 0.875 (0.778–0.973) and IL-8 0.953 (0.896–1.009). For VEGF the threshold value was 125.6 pg/ml, sensitivity 100%, specificity 71%, accuracy 79.8%. For IL-8 the threshold value was 128.78 pg/ml, sensitivity 93%, specificity 87.1%, accuracy 88.9%. In group 1, higher expression values of VEGF and CD34 angiogenesis markers in ovarian endometriomas were recorded. The highest AUC ROC was noted for CD34 — 0.844 (0.683–1.000), threshold value was 2.5%, sensitivity 90%, specificity 75%, accuracy 80.8%.</p></sec><sec><title>Conclusion</title><p>Conclusion. Risk factors for recurrence of ovarian endometriomas after operative treatment include VEGF and IL-8 levels in peritoneal fluid and expression of CD34 in the capsule.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Определить факторы риска рецидива эндометриоидных кист яичников (ЭКЯ) после хирургического лечения.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ретроспективное когортное исследование включены 82 пациентки, прооперированные впервые по поводу ЭКЯ, период наблюдения составил 30 мес. Рецидив развился у 19 пациенток (группа 1), у 63 — рецидив не диагностирован (группа 2). В качестве факторов риска рецидива оценены данные до операции (клинические особенности, уровень СА-125), во время операции (концентрация цитокинов в перитонеальной жидкости, иммуногистохимический анализ капсулы ЭКЯ), послеоперационная терапия. Для сравнения групп использовался U-критерий Манна — Уитни, точный критерий Фишера. Рассчитаны специфичность, чувствительность, точность, AUC ROC и пороговые значения.</p></sec><sec><title>Результаты</title><p>Результаты. Частота рецидивов ЭКЯ составила 23%. Не выявлено отличий между группами по возрасту, доле курящих, индексу массы тела, гинекологическому анамнезу, акушерскому статусу и послеоперационной гормональной терапии. Предоперационная концентрация СА-125 в группе 1 была выше, чем в группе 2: 62,5 Ед/мл [40,7; 112,3] vs 40,3 Ед/мл [20,3; 68,8], р &lt; 0,05. Концентрация IL-6, IL-8, TNFα, IL-1β, IL-17, VEGF, MCP 1 в перитонеальной жидкости, взятой во время операции, была статистически значимо выше в группе 1. Наибольшая AUC ROC получена для VEGF — 0,875 (0,778–0,973) и IL-8 — 0,953 (0,896–1,009). Для VEGF пороговое значение составило 125,6 пг/мл, чувствительность 100%, специфичность 71%, точность 79,8%. Для IL-8 пороговое значение составило 128,78 пг/мл, чувствительность 93%, специфичность 87,1%, точность 88,9%. В группе 1 регистрировались более высокие значения экспрессии маркеров ангиогенеза VEGF и CD34 в ЭКЯ. Наибольшая AUC ROC отмечена для CD34 — 0,844 (0,683–1,000), пороговое значение составило 2,5%, чувствительность 90%, специфичность 75%, точность 80,8%.</p></sec><sec><title>Заключение</title><p>Заключение. К факторам риска рецидива ЭКЯ после оперативного лечения относятся уровень VEGF и IL-8 в перитонеальной жидкости и экспрессия CD 34 в капсуле.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эндометриоидные кисты яичников</kwd><kwd>факторы риска рецидивирования</kwd><kwd>рецидив</kwd><kwd>углеводный антиген 125 (СА-125)</kwd><kwd>перитонеальная жидкость</kwd><kwd>сосудистый эндотелиальный фактор роста (VEGF)</kwd><kwd>интерлейкин-8 (IL-8)</kwd><kwd>CD34</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian endometrioma</kwd><kwd>risk factors of recurrence</kwd><kwd>recurrence</kwd><kwd>carbohydrate antigen 125 (CA-125)</kwd><kwd>peritoneal fluid</kwd><kwd>vascular endothelial growth factor (VEGF)</kwd><kwd>interleukin 8 (IL-8)</kwd><kwd>CD34</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Протасова А.Э, Вандеева Е.Н., Кузьмина Н.С.
