В настоящее время основным методом лечения T1N0M0 рака почки является хирургическое вмешательство, преимущественно в объеме резекции почки. Однако не все пациенты могут быть прооперированы, при этом чаще всего из-за тяжести сопутствующей патологии некоторые пациенты отказываются от операции. В таких случаях возникает необходимость поиска приемлемого альтернативного метода лечения. Таким требованиям может соответствовать стереотаксическая лучевая терапия (СТЛТ), являясь неинвазивным методом лечения почечно-клеточного рака.</p></sec><sec><title>Цель</title><p>Цель. Определить показатели общей выживаемости (ОВ), локального контроля и почечной токсичности после лечения T1N0M0 почечно-клеточного рака (ПКР) методом стереотаксической лучевой терапии.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. С 2011 по 2022 год в Челябинском областном клиническом центре онкологии и ядерной медицины 50 пациентам с верифицированным ПКР проводилась СТЛТ до 30–45 Гр за три фракции на аппарате CyberKnife. Средний возраст больных составил 69,8 года. Первичная опухоль диагностирована в 44 случаях, в 6 – рецидив после предшествующего оперативного лечения, в том числе у одного пациента – рецидив рака обеих почек. Средний объем опухоли составил 29,1 см3 .</p></sec><sec><title>Результаты</title><p>Результаты. Медиана ОВ не была достигнута, так как большинство пациентов на момент исследования живы. Показатели 1-, 3- и 5-летней ОВ – 94,8, 87,3 и 75,1% соответственно. В 74,5% случаев по критериям RECIST 1.1 спустя 6 месяцев после СТЛТ зафиксирована стабилизация процесса, в 21,6% случаях – частичный ответ, в 3,9% – прогрессирование процесса. Однолетний локальный контроль – 98%. Ренальная токсичность возникла у 26% пациентов спустя 6 месяцев после проведенной лучевой терапии, но в течение года функция почек у этих пациентов была восстановлена.</p></sec><sec><title>Выводы</title><p>Выводы. Стереотаксическая лучевая терапия T1N0M0 рака почки в СОД = 30–45 Гр позволяет стабилизировать опухолевый процесс с достаточно высокими результатами общей выживаемости и локального контроля при низкой почечной токсичности, соответственно, может быть применена в лечении неоперабельных пациентов с локализованным почечно-клеточным раком.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Currently, the main treatment for T1N0M0 kidney cancer is surgery, mainly in the amount of kidney resection. However, not all patients can be operated on, and most often due to the severity of comorbidity, some patients refuse surgery. In such cases, it becomes necessary to search for an acceptable operation of an alternative method of treatment. Such requirements can be met by stereotactic radiotherapy (SBRT), being a non-invasive method of treating renal cell carcinoma.</p></sec><sec><title>Purpose</title><p>Purpose. To determine overall survival (OS), local control, and renal toxicity after treatment of T1N0M0 renal cell carcinoma (RCC) with stereotactic radiotherapy.</p></sec><sec><title>Material and methods</title><p>Material and methods. Since 2011 to 2022 in the Chelyabinsk Regional Clinical Centre of Oncology and Nuclear Medicine, 50 patients with verified RCC underwent SBRT up to 30–45 Grey in three fractions using the CyberKnife. The mean age of the patients was 69.8 years. Primary tumor was diagnosed in 44 cases, recurrence after previous surgical treatment in 6 cases, including one patient with recurrence of cancer of both kidneys. The average tumor volume was 29.1 cm3 .</p></sec><sec><title>Results</title><p>Results. Median overall survival was not reached as most patients were alive at the time of the study. Indicators of 1-, 3- and 5-year OS are 94.8%, 87.3% and 75.1%, respectively. In 74.5% of cases, according to the RECIST 1.1 criteria, stabilization of the process was recorded 6 months after STLT, in 21.6% of cases – a partial response, in 3.9% – progression of the process. One-year local control – 98%. Renal toxicity occurred in 26% of patients 6 months after radiation therapy, but within a year, kidney function was restored in these patients.</p></sec><sec><title>Conclusions</title><p>Conclusions. Stereotactic radiation therapy T1N0M0 of kidney cancer in SOD = 30–45 Grey allows to stabilize the tumor process with sufficiently high results of overall survival and local control with low renal toxicity, respectively, can be used in the treatment of inoperable patients with localized renal cell carcinoma.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак почки</kwd><kwd>локализованный рак почки</kwd><kwd>стереотаксическая лучевая терапия</kwd><kwd>рецидив рака почки</kwd><kwd>почечная токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>kidney cancer</kwd><kwd>localized kidney cancer</kwd><kwd>stereotactic radiotherapy</kwd><kwd>kidney cancer recurrence</kwd><kwd>renal toxicity</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">Клинические рекомендации МЗ, 2021 г.
