Оценить диагностическую информативность определения концентрации маркера пролиферации МСМ5 в маточном аспирате для выявления рака тела матки и дифференциального выделения группы риска больных с подозрением на неэндометриоидный рак эндометрия.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 104 пациентки с диагнозом РТМ и 32 здоровые пациентки контрольной группы. По гистологическому типу у 79 (76 %) пациенток выявлен эндометриальный рак, у 16 (15%) – серозный и у 9 (9 %) – светлоклеточный рак. Аспирационный биоптат эндометрия получали при пайпель-биопсии с использованием двухканального катетера Pipelle. Определение концентрации МСМ5 в клеточном гомогенате маточного аспирата осуществляли методом твердофазного иммуноферментного анализа с помощью специфических тест-систем MCM5 ELISA.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что при превышении концентрации МСМ5 в маточном аспирате выше 11,38 пг/мл выявление РТМ ранних стадий возможно с диагностической чувствительностью 96,12 % и специфичностью 78,79 %. При превышении концентрации МСМ5 в маточном аспирате выше 56,9 пг/мл относительный риск выявления редких форм РТМ повышается (p &lt; 0,0001) в 59,7 раза.</p></sec><sec><title>Вывод</title><p>Вывод. Определение концентрации белка семейства минихромосомной защиты MCM5 в аспирате полости матки информативно для раннего выявления РТМ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate the diagnostic informativeness of determining the concentration of the MCM5 proliferation marker in the uterine aspirate for the detection of uterine body cancer (UBC) and the differential identifiation of the risk group for patients with suspected non-endometrioid endometrial cancer.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. 104 patients diagnosed with UBC and 32 healthy patients of the control group were examined. According to the histological type, 79 (76 %) patients had endometrial cancer, 16 (15 %) had serous and 9 (9 %) clear cell cancer. Endometrial aspiration biopsy was obtained by Pipel biopsy using a two-channel Pipelle catheter. Direct quantitative determination of the concentration of MCM5 in the uterine aspirate cell homogenate was carried out by enzyme-linked immunosorbent assay using specifi MCM5 ELISA test systems.</p></sec><sec><title>Results</title><p>Results. It was found that when the concentration of MCM5 in the uterine aspirate exceeds 11.38 pg/ml, the detection of early-stage UBC is possible with a diagnostic sensitivity of 96.12 % and a specifiity of 78.79 %. When the concentration of MCM5 in the uterine aspirate exceeds 56.9 pg/ml, the relative risk of detecting rare forms of UBC increases (p &lt; 0.0001) by 59.7 times.</p></sec><sec><title>Conclusions</title><p>Conclusions. Determination of the concentration of the protein of the minichromosomal protection family MCM5 in the aspirate of the uterine cavity is informative for the early detection of UBC.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эндометриальная аденокарцинома</kwd><kwd>серозный рак тела матки</kwd><kwd>светлоклеточный рак тела матки</kwd><kwd>аспират полости матки</kwd><kwd>дифференциальная диагностика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>endometrial adenocarcinoma</kwd><kwd>serous uterine body cancer</kwd><kwd>clear cell uterine body cancer</kwd><kwd>uterine cavity aspirate</kwd><kwd>differential diagnosis.</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">Siegel R.
