Clinical data from medical records were obtained and analyzed retrospectively, all patients underwent clinical, laboratory, and pathomorphological examination. Patients' survival rates were evaluated using the statistical method of Survival Analysis with calculation of descriptive characteristics of life time in the form of a life table and construction of Kaplan–Meier curves.</p> <p><bold>Results. </bold>In the present study, clear-cell variant of CPN occurred in 84.4 %, low-differentiated tumors – 21.9 %; synchronous metastases – 21.9 % and multiple metastases 59.4 %. A favorable prognosis according to IMDC was noted in 34.4 % of patients. Lung metastases were detected most often (53,1 %), the predominant number of patients (96.9 %) were treated with systemic therapy with targeted drugs. The length of hospital stay was 3.8 ± 6.2 % days, 30-day mortality – 3.1 %. The 3- and 5-year overall survival rates were 74 % and 62 %, respectively.</p> <p><bold>Conclusion. </bold>The tactics for cytoreductive partial nephrectomy in mRCC are currently undefined. Multivariate analysis revealed an independent negative effect of gender (<italic>p</italic> = 0.041), bone (<italic>p</italic> = 0.003) and lung (<italic>p</italic> = 0.022) metastases, and ECOG status (<italic>p </italic>= 0.03) on overall survival rates.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение. </bold>Циторедуктивная резекция почки (ЦРП) при метастатическом почечно-клеточном раке (мПКР) в настоящее время используется нечасто, и в данный момент не определены прогностические факторы, влияющие на показатели выживаемости при данном циторедуктивном хирургическом вмешательстве.</p> <p><bold>Цель исследования</bold> – определение факторов прогноза, влияющих на показатели выживаемости больных мПКР при выполнении ЦРП в реальной клинической практике.</p> <p><bold>Материалы и методы. </bold>В ретроспективное исследование включены 32 пациента, которым была выполнена ЦРП на базе Городской онкологической больницы № 62 г. Москвы и в Городском онкологическом диспансере г. Санкт-Петербурга за период с 2014 по 2022 г. Клинические данные из медицинских карт были получены и проанализированы ретроспективно, всем пациентам были проведены клинико-лабораторное, патоморфологическое исследования. Показатели выживаемости пациентов оценивали с помощью статистического метода анализа времени жизни (Survival analysis) с расчетом описательных характеристик времени жизни в форме таблицы жизни и построения кривых Каплана–Майера.</p> <p><bold>Результаты. </bold>Светлоклеточный вариант ПКР встречался у 84,4 % исследуемых, низкодифференцированные опухоли – у 21,9 %, синхронные метастазы – у 21,9 % и множественные метастазы – у 59,4 %. Благоприятный прогноз по IMDC (International Metastatic Renal Cell Carcinoma Database Consortium) отмечен у 34,4 % больных. Наиболее часто были выявлены метастазы в легких (53,1 %), преобладающему числу пациентов (96,9 %) проводилась системная терапия таргетными препаратами. Продолжительность пребывания в стационаре составила 3,8 ± 6,2 дня, 30-дневная смертность достигла 3,1 %. Показатели 3- и 5-летней общей выживаемости составили 74 и 62 % соответственно.</p> <p><bold>Заключение. </bold>На данный момент не определена тактика проведения ЦРП при мПКР. В многофакторном анализе выявлено независимое негативное влияние на показатели общей выживаемости пола (<italic>p</italic> = 0,041), метастазов в кости (<italic>p</italic> = 0,003) и легкие (<italic>p</italic> = 0,022), а также статуса ECOG (Eastern Cooperative Oncology Group) (<italic>p</italic> = 0,03).</p></trans-abstract><kwd-group xml:lang="en"><kwd>metastatic renal cancer</kwd><kwd>predictive factor</kwd><kwd>cytoreductive renal resection</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метастатический рак почки</kwd><kwd>прогностический фактор</kwd><kwd>циторедуктивная резекция почки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Padala S.A., Barsouk A., Thandra K.C. et al.
