The aim of the study is to improve the results of surgical treatment of metastases of osteogenic sarcomas in the lungs, analysis of factors that may affect the effectiveness of surgical treatment. Methods. The study included 120 patients with lung metastases of bone sarcomas who were treated from 1997 to 2013. Among the patients, there were 64 (53.3%) men and 56 (46.7%) women. The median age for diagnosis was 25 years (13 to 68 years). Most osteogenic tumors were osteosarcomas (56.7%). The indication for surgery in most cases (55%) was metastases in the lungs as the only manifestation of the disease. Most often, operations were performed with unilateral lung damage (57%). Results. Surgeries were predominantly performed with thoracotomy access. The most commonly performed surgeries were atypical lung resections. 23 (19%) patients required a lobectomy. In 113 (94%) patients, operations were performed in the volume of R0. Postoperative complications were noted in 10 (8.5%) patients. The most common postoperative complication was pneumonia, in 1 patient it led to postoperative mortality, in another patient - it led to pulmonary failure. The median followup in the study group was 53.2 months (from 3.5 months to 252 months). When analyzing the frequency of therapeutic pathomorphism in patients with bone sarcoma metastases who underwent chemotherapeutic treatment prior to resection, it was shown that the frequency of achieving complete therapeutic pathomorphism was relatively low - only in 5.5% of patients, in 15% moderate and in 79.5% of patients the effect of chemotherapy was not achieved or only a weak therapeutic pathomorphism was achieved. The overall 5-year survival rate in the study group was 56.4%. Conclusion. Surgical treatment can lead to long-term survival in patients with sarcoma metastases in the lungs, while the best treatment results are achieved with a long relapse-free interval, a small number of metastases and their removal in the amount of R0. Performing operations from thoracoscopic access does not worsen the long-term results of treatment.</p></abstract><trans-abstract xml:lang="ru"><p>Цель исследования. Целью проводимого исследования является улучшение результатов хирургического лечения метастазов остеогенных сарком в легких, анализ факторов, которые могут влиять на эффективность хирургического лечения. Материалы и методы. В исследование включены 120 пациентов с метастазами сарком костей в легких, которые получали лечение в период с 1997 по 2013 г. Среди пациентов было 64 (53,3%) мужчины и 56 (46,7%) женщин. Медиана возраста постановки диагноза составила 25 лет (от 13 до 68 лет). Большинство остеогенных опухолей были представлены остеосаркомами (56,7%). Показанием к операции в большинстве (55%) случаев были метастазы в легких в качестве единственного проявления заболевания. Наиболее часто операции выполнялись при одностороннем поражении легкого (57%). Результаты. Операции преимущественно выполнялись из торакотомного доступа. Наиболее часто выполняемым объемом операции были атипичные резекции легкого. 23 (19%) пациентам потребовалось выполнение лобэктомии. У 113 (94%) пациентов операции были выполнены в объеме R0. Послеоперационные осложнения отмечены у 10 (8,5%) пациентов. Наиболее частым послеоперационным осложнением была пневмония, у 1 пациента она послужила причиной послеоперационной летальности, еще у 1 пациента - причиной развития легочной недостаточности. Медиана наблюдения в исследуемой группе составила 53,2 мес (от 3,5 до 252 мес). При анализе частоты лечебного патоморфоза у пациентов с метастазами сарком костей, которым до резекции проводилось химиотерапевтическое лечение, показано, что частота достижения полного лечебного патоморфоза была относительно низкой - только у 5,5% пациентов, у 15% умеренный, и у 79,5% пациентов не достигнуто эффекта от химиотерапии или достигнут лишь слабый лечебный патоморфоз. Общая 5-летняя выживаемость в исследуемой группе составила 56,4%. Заключение. Хирургическое лечение может привести к долгосрочной выживаемости у пациентов с метастазами сарком в легких, при этом наилучшие результаты лечения достигаются при наличии длительного безрецидивного интервала, небольшого количества метастазов и их удалении в объеме R0. Выполнение операций из торакоскопического доступа не ухудшает отдаленные результаты лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>thoracotomy</kwd><kwd>osteosarcoma</kwd><kwd>pulmonary metastasis</kwd><kwd>surgical treatment</kwd><kwd>computed tomography</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>торакотомия</kwd><kwd>остеосаркома</kwd><kwd>метастазы в легкие</kwd><kwd>хирургическое лечение</kwd><kwd>компьютерная томография</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Pastorino U.
