Изучение взаимосвязи опухолевого поражения НСМ с традиционными клинико-морфологическими факторами прогноза и влияния данного параметра на результаты лечения раннего эндометриоидного РТМ.Пациенты и методы. В исследование были включены 506 пациенток с эндометриоидным РТМ I стадии (по классификации Международной федерации гинекологов и акушеров (International Federation of Gynaecology and Obstetrics – FIGO)), проходивших хирургическое или комбинированное лечение в Медицинском радиологическом научном центре им. А. Ф. Цыба – филиал ФГБУ «НМИЦ радиологии» (г. Обнинск, Российская Федерация) в 2002–2024 гг. Медиана наблюдения составила 81,1 мес. Пациентки были разделены на две группы в зависимости от наличия или отсутствия опухолевого поражения НСМ по данным гистологического заключения: соответственно 1-я группа – 175 (34,6 %) пациенток, 2-я группа – 331 (65,4 %) пациентка.Результаты. Вовлечение НСМ было установлено у 34,6 % больных. Обнаружено, что у данных пациенток чаще встречались такие факторы, как лимфоваскулярная инвазия (ЛВИ) (р &lt; 0,001) и глубокая инвазии в миометрий (р &lt; 0,001). В целом, поражение НСМ зарегистрировано у 23 % больных с отсутствием традиционных неблагоприятных факторов прогноза и у 50 % – с наличием этих факторов (р &lt; 0,001). При этом более распространенные формы заболевания, влияющие на изменение патоморфологической стадии, чаще были обнаружены в группе больных с поражением НСМ – 20,0 % против 5,1 % в группе без вовлечения НСМ (р &lt; 0,001). Таким образом, при поражении НСМ риск обнаружения после гистологического исследования более распространенного опухолевого процесса повышается в 3,9 раза по сравнению со случаями отсутствия поражения НСМ. Анализ выживаемости на текущем сроке наблюдения показал статистически значимое снижение показателей общей и пятилетней выживаемости больных РТМ I стадии при поражении НСМ – соответственно 87,9 % и 75,3 ± 4,8 % по сравнению с 93,4 % и 93,1 ± 2,5 % – без поражения НСМ (соответственно р = 0,044 и р &lt; 0,001).Заключение. Опухолевое поражение НСМ можно рассматривать в качестве потенциального диагностического предиктора обнаружения более распространенных форм РТМ I стадии и прогностического показателя неблагоприятного исхода эндометриоидного заболевания.</p></abstract><trans-abstract xml:lang="en"><p>In modern clinical practice, when deciding on the amount of adjuvant therapy for cancer of the uterine body (UBC), such a factor as a tumor lesion of the lower uterine segment (LUS) is not considered, although a number of studies indicate its possible connection with a more aggressive course of the disease.Purpose of the study. To study the relationship between tumor involvement of the LUS and traditional clinical and morphological prognostic factors, and the impact of this parameter on the treatment outcomes of early endometrial cancer.Patients and methods. The study included 506 patients with stage I endometrioid UBC according to the classification of the International Federation of Gynecologists and Obstetricians (FIGO) who underwent surgical or combined treatment at the A. Tsyb Medical Radiological Research Center – Branch of the National Medical Research Radiological Center (Obninsk, Russian Federation) in 2002–2024. The median follow-up was 81.1 months. The patients were divided into two groups depending on the presence or absence of a tumor lesion of the LUS according to the histological conclusion: respectively Group 1–175 (34.6 %) patients, group 2–331 (65.4 %) patients.Results. LUS involvement was found in 34.6 % of patients. It was found that these patients more often had factors such as lymphovascular invasion (LVI) (p &lt; 0.001) and deep invasion into the myometrium (p &lt; 0.001). Overall, LUS involvement was recorded in 23 % of patients without traditional unfavorable prognostic factors and in 50 % of patients with these factors (p &lt; 0.001). At the same time, more common forms of the disease affecting the pathomorphological stage were more frequently detected in the group of patients with LUS involvement – 20.0 % versus 5.1 % in the group without LUS involvement (p &lt; 0.001). Thus, in cases of LUS involvement, the risk of detecting a more common tumor process after histological examination increases 3.9 times compared to cases without LUS involvement. Survival analysis at the current follow-up period showed a statistically significant decrease in overall and five-year survival rates in patients with stage I UBC with LUS involvement – 87.9 % and 75.3 ± 4.8 %, respectively, compared with 93.4 % and 93.1 ± 2.5 % without LUS involvement (with p = 0.044 and p &lt; 0.001, respectively).Conclusion. Tumor involvement of the LUS can be considered a potential diagnostic predictor for the detection of more common forms of stage I UBC and a prognostic indicator of an unfavorable outcome of endometrioid disease.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак тела матки</kwd><kwd>нижний сегмент матки</kwd><kwd>эндометриоидная аденокарцинома</kwd><kwd>факторы риска прогрессирования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>uterine cancer</kwd><kwd>lower uterine segment</kwd><kwd>endometrioid adenocarcinoma</kwd><kwd>risk factors for progression</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">Злокачественные новообразования в России в 2023 году (заболеваемость и смертность).
