При этом стандартный подход, предусматривающий введение всем пациентам одних и тех же цитостатиков (доксорубицин, цисплатин, метотрексат) и перед, и после операции, остается неизменным на протяжении последних десятилетий. К сожалению, результаты его использования у больных с плохим ответом (патоморфозом) опухоли на предоперационную ХТ малоудовлетворительны, а недавно завершившиеся исследования не показали их улучшения за счет интенсификации послеоперационной ХТ. В результате стандартом лечения этих больных остается продолжение после операции ХТ, оказавшейся неэффективной на дооперационном этапе. Статья посвящена критическому анализу целесообразности подобной практики и оценке возможных позитивных и негативных последствий отказа от послеоперационной ХТ у больных с плохим патоморфозом опухоли.</p><p> </p></abstract><trans-abstract xml:lang="en"><p>Chemotherapy (CT) has significantly increased the chance of cure for patients with resectable osteogenic sarcoma and is now an integral part of their treatment. At the same time, the standard approach is represented by administration of the same СT (doxorubicin, cisplatin, methotrexate) to all patients both before and after the surgery has remained unchanged over the past decades. Unfortunately, the results of its application in patients with a poor pathologic response of a tumor to preoperative CT are not satisfactory, and recently published studies have not shown their improvement due to the intensification of postoperative CT. As a result, the standard of treatment for these patients remains a continuation after surgery the same CT, which has proved ineffective at the preoperative stage. The article is devoted to a critical analysis of the feasibility of such practices and an assessment of the possible positive and negative consequences of the rejection of postoperative CT in patients with poor pathologic response.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>остеогенная саркома</kwd><kwd>лечебный патоморфоз</kwd><kwd>неоадъювантная терапия</kwd><kwd>адъювантная терапия</kwd><kwd>выживаемость</kwd><kwd>клинические исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteogenic sarcoma</kwd><kwd>medical pathomorphosis</kwd><kwd>neoadjuvant therapy</kwd><kwd>adjuvant therapy</kwd><kwd>survival</kwd><kwd>clinical studies</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование проведено без спонсорской поддержки.</funding-statement><funding-statement xml:lang="en">The study was performed without external funding.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">DeVita V.T.
