These agents have expanded the treatment options for cancer patients. Despite the impressive success achieved in the development of immune checkpoint inhibitors (ICIs) and subsequent approval in a broader spectrum of malignant tumors, most patients are not responded the therapy. Currently available predictive markers of efficacy are nonspecific. However, microRNAs are of particular interest, which regulate gene expression and are involved in the carcinogenesis and therapy resistance. Therefore, it is clear that for the most efficient and cost-effective use of ICIs, it is important to have validated biomarkers that will accurately predict the therapeutic response. The published results on molecular genetic changes in patients with renal cell carcinoma (RCC) were analyzed and summarized in order to determine possible prognostic biomarkers when prescribing ICI therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Иммунотерапия онкологических заболеваний включает применение методов лечения для стимуляции иммунной системы и косвенного подавления роста опухолевых клеток. Применение иммуннотерапевтических препаратов позволило расширить возможности лечения онкологических больных. Несмотря на впечатляющий успех, достигнутый в разработке ингибиторов контрольной точки иммунитета (ИКТИ), большинство пациентов не демонстрируют ответа на терапию. Имеющиеся на данный момент маркеры эффективности являются неспецифичными. Для наиболее эффективного и экономичного применения ИКТИ важно идентифицировать специфичные биомаркеры, которые позволят предсказать терапевтический ответ на терапию с высокой точностью и специфичностью. Особый интерес представляют микроРНК, которые регулируют экспрессию генов, вовлечены в процесс канцерогенеза и резистентности к терапии. В статье проведены анализ и обобщение результатов исследований молекулярно-генетических изменений у пациентов с почечно-клеточной карциномой (ПКК) с целью их возможного использования в качестве прогностических биомаркеров при назначении терапии ИКТИ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>immunotherapy</kwd><kwd>resistance</kwd><kwd>exosomal microRNAs</kwd><kwd>prognostic markers</kwd><kwd>renal cell carcinoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>иммунотерапия</kwd><kwd>резистентность</kwd><kwd>экзосомальные микроРНК</kwd><kwd>прогностические маркеры</kwd><kwd>почечно-клеточная карцинома</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This study was funded by Russian Science Foundation, grant number 23-25-00392 “Exosomal microRNAs as possible predictors of antitumor efficacy of immune checkpoint inhibitors”.</funding-statement><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке гранта РНФ № 23-25-00392 «Экзосомальные микроРНК как возможные предикторы противоопухолевой эффективности ингибиторов контрольных точек иммунного ответа».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ross K., Jones R.J.
