There is still no consensus on the feasibility of repeated surgeries for lung metastases.<bold>Aim</bold>. To compare the short-term and long-term outcomes of primary and repeated surgeries for lung metastases.<bold>Materials and methods</bold>. This retrospective study included patients with lung metastases from colorectal cancer, germ cell tumors, renal cell carcinoma, osteogenic sarcomas, and soft tissue sarcomas operated on in N. N. Blokhin National Medical Research Center of Oncology between 1997 and 2017. Overall survival and the incidence of postoperative complications (Clavien–Dindo classification) were the main parameters evaluated.<bold>Results</bold>. We identified 613 patients who had undergone resection of lung metastases; of them, 65 patients (10.6) had had repeated surgeries for lung metastases. R0 resection was the only prognostic factor for overall survival in patients with repeated surgeries for lung metastases (hazard ratio 7.691; 95 % confidence interval 3.163–18.702; р &lt;0.001). Postoperative complications were observed in 48 patients after primary surgeries (7.8 %) and 11 patients after repeated surgeries (16.9 %) (р = 0.02). Five patients after primary surgeries (0.8 %) and 2 patients after secondary surgeries (3.1 %) died (р = 0.139). R0 resections were achieved in 576 (94 %) and 57 (87.7 %) patients after primary and secondary surgeries, respectively (р = 0.065). The five-year overall survival rate was 61.2 % after primary surgery and 53 % after repeated surgery (р = 0.91).<bold>Conclusions</bold>. Repeated surgeries for resectable lung metastases ensure long-term outcomes comparable to those after primary operations. Repeated surgeries are associated with an increased risk of postoperative complications, but not postoperative mortality</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение</bold>. Отсутствует консенсус относительно оправданности повторных операций по поводу метастазов злокачественных новообразований в легких.<bold>Цель исследования</bold> – сравнительный анализ непосредственных и отдаленных результатов после первичных и повторных резекций легких, выполненных по поводу их метастатического поражения.<bold>Материалы и методы</bold>. Выполнен ретроспективный анализ историй болезни пациентов, которым выполняли удаление метастазов в легких в ФГБУ «Национальный медицинский исследовательский центр онкологии им. Н.Н. Блохина» Минздрава России в период с 1997 по 2017 г. В анализ включались пациенты с метастазами колоректального рака, герминогенных опухолей, рака почки, остеогенных сарком и сарком мягких тканей. Основными оцениваемыми параметрами были общая выживаемость и частота послеоперационных осложнений (Clavien–Dindo).<bold>Результаты</bold>. В архиве клиники были идентифицированы данные 613 пациентов, которым была выполнена резекция метастазов в легких, из них 65 (10,6 %) пациентам были выполнены повторные операции по поводу метастазов злокачественных новообразований в легких. Единственным прогностическим критерием общей выживаемости для повторных операций по поводу метастазов в легких было их удаление в объеме R0: отношение рисков 7,691; 95 % доверительный интервал 3,163–18,702; р &lt;0,001. Послеоперационные осложнения развились у 48 (7,8 %) больных после первичных операций и у 11 (16,9 %) – после повторных (р = 0,02). Послеоперационная летальность отмечена у 5 (0,8 %) и 2 (3,1 %) пациентов соответственно (р = 0,139). Частота R0-резекций составила 576 (94 %) и 57 (87,7 %) соответственно (р = 0,065). Пятилетняя общая выживаемость составила 53 % у пациентов, которым было выполнено повторное удаление метастазов, и 61,2 % у пациентов, оперированных однократно (р = 0,91).<bold>Выводы</bold>. Повторное удаление резектабельных метастазов злокачественных новообразований в легких позволяет добиться отдаленных результатов, сопоставимых с таковыми при первичном лечении. Выполнение повторных операций связано с повышенным риском развития послеоперационных осложнений, но не послеоперационной летальности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>lung metastases</kwd><kwd>repeated surgeries</kwd><kwd>surgical treatment</kwd><kwd>postoperative complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>метастазы в легких</kwd><kwd>повторные операции</kwd><kwd>хирургическое лечение</kwd><kwd>послеоперационные осложнения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
