С 2011 по 2021 г. на базе Челябинского областного клинического центра онкологии и ядерной медицины (ЧОКЦО и ЯМ) 42 пациентам с морфологически верифицированным диагнозом рака почки проводилась СТЛТ до СОД от 30 до 45 Гр за 3 фракции на аппарате CyberKnife. СТЛТ проводилась в случае неоперабельности пациента с учетом различных факторов (возраст, тяжесть сопутствующей патологии, степень анестезиологического риска ASA IV), отказа пациентов от хирургического лечения, в случае размеров опухоли до 5,0 см в диаметре. Не проводилась СТЛТ при размерах опухоли более 5,0 см в диаметре, при значимом нарушении функции почек (хроническая болезнь почек С5), генерализации процесса, при декомпенсации сопутствующей патологии. Средний возраст больных составил 67,9 года. У 93 % пациентов была I стадия рака почки. Первичная опухоль была диагностирована в 37 случаях, в 6 – рецидив после предшествующего оперативного лечения, в том числе у 1 пациента – рецидив рака обеих почек. Средний объем опухоли составил 28,1 см3.</p></sec><sec><title>Результаты</title><p>Результаты. Медиана общей выживаемости (ОВ) не была достигнута в связи с тем, что большинство пациентов (n=36) на момент анализа результатов исследования были живы. Показатели 1-, 3- и 5-летней ОВ составили 94,1; 88,7 и 72,6 % соответственно. Зафиксирован уровень 1-летнего локального контроля в 93 %. Частичный ответ по критериям RECIST 1.1 спустя 3–6 мес после СТЛТ отмечен в 26,2 % случаев, в 66,8 % – стабилизация процесса, в 7 % (n=3) – прогрессирование процесса. Ренальная токсичность возникла у 23,8 % пациентов спустя 3 мес после проведенной лучевой терапии, но в течение года функция почек у этих пациентов была восстановлена.</p></sec><sec><title>Заключение</title><p>Заключение. СТЛТ рака почки демонстрирует высокую эффективность при минимальной токсичности, что позволяет применять данный метод в лечении рака почки у неоперабельных пациентов.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study: to evaluate the overall survival and local control in patients with inoperable kidney cancer treated with stereotactic body radiotherapy (SBRT).</p></sec><sec><title>Material and Methods</title><p>Material and Methods. From 2011 to 2021, 42 patients with histologically verified kidney cancer underwent SBRT to a total dose ranging from 30 to 45 Gr in 3 fractions using the CyberKnife robotic radiosurgical system. SBRT was performed for inoperable patients, taking into account various factors (age, severity of concomitant pathology, ASA IV physical status level), patients’ refusal of surgical treatment, and tumor size of ≤5.0 cm in diameter. SBRT was not performed for patients with tumor size of ≥5.0 cm in diameter, impaired renal function, generalization of cancer and decompensation of concomitant pathology. The median age of the patients was 67.9 years. 93 % of patients had stage I kidney cancer. The primary tumor was diagnosed in 37 cases, recurrence after previous surgical treatment in 6, including 1 patient with recurrence of cancer of both kidneys. The average tumor volume was 28.1 cm3.</p></sec><sec><title>Results</title><p>Results. The median overall survival (OS) was not reached due to the fact that the majority of patients (n=36) were alive at the time of the study. The 1-, 3- and 5-year OS rates were 94.1 %, 88.7 %, and 72.6 %, respectively. The 1-year local control rate was 93 %. At 3-6 months, 26.2 % of patients showed partial response, 66.8 % had stable disease and 7 % had disease progression (according to the RECIST 1.1 criteria). Renal toxicity occurred in 23.8 % of patients 3 months after radiation therapy; however, kidney function was restored in these patients within a year.</p></sec><sec><title>Conclusion</title><p>Conclusion. SBRT has demonstrated high efficacy with minimal toxicity in the treatment of inoperable patients with kidney cancer. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>стереотаксическая лучевая терапия</kwd><kwd>рак почки</kwd><kwd>рецидив рака почки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>stereotactic radiation therapy</kwd><kwd>kidney cancer</kwd><kwd>recurrent kidney cancer</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">NCCN Guidelines Updates: Kidney Cancer. 2022; 20(1). https://doi.org/10.6004/jnccn.2022.201glup.</mixed-citation><mixed-citation xml:lang="en">NCCN Guidelines Updates: Kidney Cancer. 2022; 20(1). https://doi.org/10.6004/jnccn.2022.201glup.</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">de la Pinta C., Latorre R.G., Fuentes R.
