In 15–20% of patients, distant metastases are detected at the time of diagnosis of OS. In more than 80% of cases, metastases are located in the lungs and are the most common disease-related cause of death in OS patients. OS can only be cured if complete surgical remission (CSR) in the lungs is achieved through surgery involving palpation, identification and resection of all detected metastases. Among thoracic surgeons, it is common practice to perform wedge resection of the affected lung parenchyma as it spares more healthy lung tissue. Lobectomy or pneumonectomy can be carried out if either is indicated in the patient. There is, however, no consensus on the best surgical approach for metastasectomy. Our study includes 24 patients who underwent simultaneous bilateral thoracotomy at the Department of Oncology and Pediatric Surgery of the D. Rogachev NMRCPHOI in the period from February 2018 to May 2021. The study was approved by the Independent Ethics Committee and the Scientific Council of the D. Rogachev NMRCPHOI. Eighteen patients underwent primary surgery as part of combination protocol treatment, and six patients were surgically treated for relapse. In 66.7% of the patients treated with upfront surgery, the number of lesions was underestimated, as evident from computed tomography images and intraoperative findings. Post-treatment necrosis grade IV was detected only in 3 patients, in 21.1% of the resected metastases. The median time from bilateral thoracotomy to systemic anti-cancer therapy reinitiation was 12 days. Two patients experienced progression of metastatic disease in the lungs during and immediately the protocol treatment. At the last follow-up, 3 patients were alive with evidence of disease, and 2 patients had died of OS progression. A total of 33.3% of the patients who had had primary surgery developed metastatic (n = 6) and local (n = 1) relapses. </p></abstract><trans-abstract xml:lang="ru"><p>Остеосаркома (ОС) – самая частая первичная опухоль костей у детей и взрослых. Выявление отдаленных метастазов на момент постановки диагноза ОС имеет место у 15–20% пациентов. Более чем в 80% случаев метастазы локализуются в легких и наиболее часто являются причиной болезньассоциированной смерти пациентов с ОС. Излечение от ОС возможно только в случае достижения полной хирургической ремиссии в легких путем проведения оперативного вмешательства с мануальной пальпацией, обнаружением и удалением всех определяемых метастазов. Среди специалистов, занимающихся торакальной хирургией, общепринятым является проведение клиновидной резекции паренхимы с патологическими очагами, позволяющей сохранить больший объем ткани легкого, по показаниям – выполнение лобэктомии или пульмонэктомии. При этом единого мнения в отношении выбора оперативного доступа при проведении метастазэктомии нет. В настоящее исследование включены 24 пациента, которым в период с февраля 2018 г. по май 2021 г. в отделении онкологии и детской хирургии НМИЦ ДГОИ им. Дмитрия Рогачева проведены симультанные билатеральные торакотомии. Данное исследование одобрено независимым этическим комитетом и утверждено решением ученого совета НМИЦ ДГОИ им. Дмитрия Рогачева. Восемнадцати пациентам операция проведена первично в рамках комбинированного протокольного лечения, 6 – в рецидиве заболевания. У 66,7% пациентов, оперированных первично, по результатам компьютерной томографии и последующих операций количество очагов было недооценено. Только у 3 пациентов и в 21,1% удаленных метастазов выявлена IV степень посттерапевтического патоморфоза. Медиана срока возобновления системного противоопухолевого лечения после билатеральной торакотомии составила 12 дней. У 2 пациентов отмечалась метастатическая прогрессия в легких на терапии и непосредственно после завершения протокольного лечения. При катамнестическом наблюдении 2 пациента умерли от прогрессии ОС, 3 – живы с признаками болезни. У 33,3% пациентов, оперированных первично, развились метастатический (n = 6) и локальный (n = 1) рецидивы. </p></trans-abstract><kwd-group xml:lang="en"><kwd>osteosarcoma</kwd><kwd>pulmonary metastases</kwd><kwd>lesions</kwd><kwd>computed tomography</kwd><kwd>surgical treatment of metastasis</kwd><kwd>thoracotomy</kwd><kwd>bilateral thoracotomy</kwd><kwd>children</kwd><kwd>adolescents</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>остеосаркома</kwd><kwd>метастазы в легких</kwd><kwd>очаги</kwd><kwd>компьютерная томография</kwd><kwd>хирургия метастазов</kwd><kwd>торакотомия</kwd><kwd>билатеральная торакотомия</kwd><kwd>дети</kwd><kwd>подростки</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Meyers P.A., Heller G., Healey J.H., Huvos A., Applewhite A., Sun M., et al.
