Анализ ранних иммуноопосредованных нежелательных явлений (ИНЯ) иммунотерапии ингибиторами PD‑1 пациентов с метастатическим раком паренхимы почки.Материалы и методы. Под наблюдением находились 97 пациентов обоих полов (медиана возраста 62 года) с метастатическим почечноклеточным раком: IV стадии de novo, или прогрессирование с возникновением отдаленных метастазов при более ранней стадии заболевания. Пациенты получали в монорежиме пембролизумаб, гуманизированное моноклональное антитело, которое селективно блокирует взаимодействие между рецептором PD‑1 и его лигандами PD-L1 и PD-L2. Препарат вводили при внутривенной инфузии в дозировке 400 мг 1 раз в 42 дня. На протяжении всего срока наблюдения осуществлялся постоянный мониторинг с включением клиникоинструментальных и лабораторных методов исследования. Для оценки видов и степени выраженности / тяжести ИНЯ использовали шкалу NCI CTCAE V6.0.Результаты. Было зарегистрировано общее количество ИНЯ – 228 случаев (в среднем 2,35 на пациента). Наиболее часто встречающимися ранними ИНЯ 1–2 степени тяжести были почечная (54,7%), кожная (49,5%), гастроинтестинальная (36,1%), печеночная (16,5%), легочная (12,4%), эндокринная (12,4%) и гематологическая (11.3%) токсичность.Заключение. Понимание временной динамики и профиля токсических эффектов анти-PD‑1 имеет первостепенное значение для постоянного мониторинга, эффективного клинического ведения пациентов.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the study was to analyse early immune-mediated adverse events (IMAEs) of PD‑1 inhibitor immunotherapy in metastatic renal cell carcinoma patients.Materials and methods. 97 patients of both sexes (median age 62 years) with metastatic renal cell carcinoma: stage IV de novo or progression with distant metastases from an earlier stage of the disease were under observation. Patients as a single agent received pembrolizumab, a humanized monoclonal antibody that selectively blocks the interaction between the PD‑1 receptor and its ligands PD-L1 and PD-L2. The drug was administered by intravenous infusion at a dose of 400 mg every 42 days.Continuous monitoring, including clinical, instrumental and laboratory tests, was performed throughout the entire observation period. The NCI CTCAE V6.0 scale was used to assess the types and severity of AEs. Results. A total of 228 AEs were recorded (an average of 2.35 per patient). The most common early grade 1–2 AEs were renal (54.7%), cutaneous (49.5%), gastrointestinal (36.1%), hepatic (16.5%), pulmonary (12.4%), endocrine (12.4%), and hematological (11.3%) toxicity.Conclusion. Understanding the time course and toxicity profile of anti-PD‑1 is crucial for ongoing monitoring and effective clinical management of patients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>метастатический почечно-клеточный рак</kwd><kwd>иммунотерапия</kwd><kwd>ингибиторы PD-1</kwd><kwd>нежелательные явления</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metastatic renal cell carcinoma</kwd><kwd>immunotherapy</kwd><kwd>PD-1 inhibitors</kwd><kwd>adverse events</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">Parvez A, Choudhary F, Mudgal P, Khan R, Qureshi KA, Farooqi H, Aspatwar A.
