However, only 30 % of patients with advanced or metastatic EC have a clinical response when treated with pembrolizumab and lenvatinib. In this regard, there is an obvious need to identify biomarkers that allow accurate selection of candidates for this type of therapy.<bold>Aim. </bold>To determine the predictive value of subpopulations of lymphocytes and macrophages, their expression of PD-1, expression of estrogen receptors, as well as vessel density in immunotargeted therapy for advanced or metastatic EC.<bold>Materials and methods. </bold>An open-label non-randomized observational association study was performed, involving a total of 22 patients with advanced or metastatic MSS/pMMR EC treated with pembrolizumab and lenvatinib. Duration of clinical effectiveness was used as a parameter to stratify patients. Using TSA-associated multiplex immunofluorescence, the proportions of CD8+ T lymphocytes, CD20+ B lymphocytes, FoxP3+ T regulatory lymphocytes and CD163+macrophages in tumor samples before the start of immunotargeted therapy were analyzed.<bold>Results. </bold>Three microenvironmental parameters were found to be associated with duration of clinical efficacy: the proportion of CD20+ B cells, the proportion of FoxP3+ T regulatory lymphocytes, and the ratio of CD8+/CD20+ lymphocytes in the tumor microenvironment. However, the CD8+/CD20+ lymphocyte ratio had the greatest predictive value; a value below 3.219 was associated with long clinical efficacy in patients with advanced or metastatic EC.<bold>Conclusion. </bold>The ratio of cytotoxic and B-lymphocytes in the microenvironment is a reliable predictor marker of the duration of the period of clinical effectiveness of immunotargeting therapy in advanced or metastatic EC.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Включение ленватиниба в схему иммунотерапии у больных MSS/pMMR раком эндометрия (РЭ) обусловлено его способностью модулировать микроокружение опухоли, что позволяет использовать пембролизумаб в низкоиммуногенных опухолях. Тем не менее только у 30 % пациенток с прогрессирующим или метастатическим РЭ при комбинированном лечении пембролизумабом и ленватинибом наблюдается клинический ответ. В связи с этим очевидна потребность в выявлении биомаркеров, позволяющих точно отбирать кандидаток для данного вида терапии.</p><p><bold>Цель исследования </bold>– определение предикторной ценности субпопуляций лимфоцитов и макрофагов, экспрессии на них PD-1, экспрессии эстрогеновых рецепторов, а также плотности сосудов при иммунотаргетной терапии прогрессирующего или метастатического РЭ.</p><p><bold>Материалы и методы. </bold>Проведено открытое нерандомизированное обсервационное ассоциативное исследование, включавшее в общей сложности 22 пациентки с прогрессирующим или метастатическим MSS/pMMR РЭ, которые получали терапию пембролизумабом и ленватинибом. В качестве параметра для стратификации пациенток была использована продолжительность клинической эффективности. С помощью TSA-ассоциированной мультиплексной иммунофлуоресценции были проанализированы доли CD8+ Т-лимфоцитов, CD20+ В-лимфоцитов, FoxP3+ Т-регуляторных лимфоцитов и CD163+ макрофагов в образцах опухоли до начала иммунотаргетной терапии.</p><p><bold>Результаты. </bold>Были обнаружены 3 параметра микроокружения, которые связаны с продолжительностью клинической эффективности: доля CD20+ В-лимфоцитов, доля FoxP3+ Т-регуляторных лимфоцитов и соотношение CD8+/CD20+ лимфоцитов в опухолевом микроокружении. Однако наибольшей предикторной ценностью обладало соотношение CD8+/CD20+ лимфоцитов, значение которого ниже 3,219 было ассоциировано с длительной клинической эффективностью у больных прогрессирующим или метастатическим РЭ.</p><p><bold>Выводы. </bold>Соотношение цитотоксических и В-лимфоцитов в микроокружении является надежным предикторным маркером длительности периода клинической эффективности иммунотаргетной терапии при прогрессирующем или метастатическом РЭ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>endometrial cancer</kwd><kwd>immunotargeted therapy</kwd><kwd>predictors of response</kwd><kwd>progression-free survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак эндометрия</kwd><kwd>иммунотаргетная терапия</kwd><kwd>предикторы ответа</kwd><kwd>выживаемость без прогрессирования</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was performed with financial support from the Russian Science Foundation (grant No. 20-75-10033-P).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 20-75-10033-П).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Shakhzadova A.O., Starinsky V.V., Lisichnikova I.V.
