About one quarter of all patients belong to a high-risk group characterized by a poor prognosis. In spite of high-dose chemotherapy (HDCT) with autologous hemopoietic stem cell transplantation (auto-HSCT) being traditionally viewed as a possible option for high-risk patients, there is stills no consensus on indications for this method in EWS patients.</p><p><bold>Study objective:</bold> to evaluate the HDCT effectiveness and most important prognostic factors in a prospective cohort of high-risk EWS patients. Materials and methods. A total of 73 EWS patients receiving treatment in R.M. Gorbacheva Memorial Institute were included in the study. All patients were characterized by one or several high-risk features: local (primary tumor volume &gt;200 ml, axial localization, poor response to chemotherapy; n = 55; 76 %), primary disseminated disease (n = 58; 80 %), first chemoresponsive relapse (n = 7; 9 %). All patients received a myeloablative consolidation regimen consisting of busulfan 16mg/kg and melphalan 140mg/m<sup>2</sup>. In patients with primary disseminated disease an additional evaluation according to risk scale by R. Ladenstein et al. was performed. Based on risk points all patients were stratified as standard (n = 20), high (n = 26), and ultrahigh risk (n = 12).</p><p><bold>Results.</bold> The 5-year overall and event-free survivalfor a whole studied cohort were 40 and 37 %, accordingly. In patients with high-risk localized disease the 5-year overall and event-free survival were 48 and 45 %, accordingly. The HDCT regimen was characterized by acceptable toxicity. The main non-hematologic toxicities were infectious complications (n = 61) and gastrointestinal tract mucositis (n = 31). One patient of 76 died due to treatment-related complications. The multivariate analysis revealed the following risk factors: therapy response (hazard ratio (HR) 2.2; p &lt;0.01), bone marrow involvement (HR 5.0; p = 0.01), primary tumor volume (HR 1.9; p = 0.01), and number of bone metastases (HR 2.2; p = 0.05). The risk group determined by R. Ladenstein score was also a good predictor for outcome with only 8 % of ultrahigh risk patients surviving 5 years past auto-HSCT.</p><p><bold>Conclusion. </bold>HDCT with auto-HSCT may potentially improve treatment results in some high-risk patient subgroups. While risk scale may help to determine patients most likely to benefit from this approach, the outcome in ultrahigh risk patients are still dismal.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Саркома Юинга (СЮ) — 2-я по частоте встречаемости злокачественная опухоль костной ткани у детей. Более четверти пациентов относятся к группе высокого риска с крайне неблагоприятным прогнозом. Несмотря на то что высокодозная полихимиотерапия (ВДПХТ) с аутологичной трансплантацией гемопоэтических стволовых клеток (ауто-ТГСК) рассматривается как один из способов улучшения результатов в группе неблагоприятного прогноза, единый подход к использованию этого метода пока отсутствует.</p><p><bold>Цель исследования</bold> — оценить эффективность применения ВДПХТ с ауто-ТГСК и описать основные прогностические факторы в проспективной когорте пациентов с СЮ группы высокого риска.</p><p><bold>Материалы и методы</bold>. В исследование включены 73 пациента с СЮ, получавших лечение в НИИДОГиТ им. Р.М. Горбачевой. Все пациенты относились к группе высокого риска в связи с выявлением одного или нескольких факторов риска: локальных (исходный объем опухоли &gt;200 мл, осевая локализация, плохой ответ на терапию; n = 55; 76 %), метастатического поражения (п = 58; 80 %), развития химиочувствительного рецидива заболевания (п = 7; 9 %). Всем пациентам проводилась ВДПХТ по схеме бусуль-фан 16мг/кг, мелфалан 140мг/м<sup>2</sup>. Для дополнительной оценки факторов риска у пациентов с первично-диссеминированными формами заболевания использована балльная шкала R. Ladenstein и соавт., в соответствии с которой пациентов делили на группы стандартного (n = 20), высокого (n = 26) и сверхвысокого (n = 12) риска.</p><p><bold>Результаты.</bold> Пятилетняя общая и бессобытийная выживаемость для всей группы пациентов составила 40 и 37 % соответственно. В группе пациентов с неоперабельным первичным очагом осевой локализации 5-летняя общая и бессобытийная выживаемость составила 48 и 45 % соответственно. Режим характеризовался приемлемой токсичностью, основными негематологическими проявлениями были инфекционные осложнения (n = 61) и мукозит желудочно-кишечного тракта (n = 31). Один пациент умер в связи с развитием осложнений. В рамках многофакторного анализа основными факторами риска были ответ на полихимиотерапию (hazard ratio (HR) 2,2;p &lt;0,01), поражение костного мозга (HR 5,0;p = 0,01), объем первичного очага (HR 1,9;p = 0,01), число метастазов в кости (HR 2,2;p = 0,05). Значение по шкале R. Ladenstein коррелировало с прогнозом заболевания, 5-летняя общая выживаемость в группе сверхвысокого риска составила 8 %.</p><p><bold>Заключение.</bold> ВДПХТ с ауто-ТГСК потенциально способна улучшить результаты лечения у пациентов с СЮ группы высокого риска. Клиническая балльная шкала позволяет прогнозировать исход заболевания. Прогноз группы сверхвысокого риска остается крайне неблагоприятным.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Ewing sarcoma</kwd><kwd>high-risk group</kwd><kwd>high-dose chemotherapy</kwd><kwd>autologous hemopoietic stem cell transplantation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркома Юинга</kwd><kwd>группа высокого риска</kwd><kwd>высокодозная химиотерапия</kwd><kwd>аутологичная трансплантация гемопоэтических стволовых клеток</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Delatte O., Zucman J., Plougastel B. et al.
