Одной из возможных опций эскалации интенсивности терапии у пациентов со злокачественными опухолями группы высокого риска является высокодозная химиотерапия (ВДХТ) с последующей аутологичной трансплантацией гемопоэтических стволовых клеток (аутоТГСК). Тем не менее, указанный метод имеет высокие риски развития ранней и отдаленной токсичности и не во всех случаях отвечает ожидаемой эффективности. Это актуализирует необходимость более деликатного подхода к выбору категории пациентов для использования данной опции лечения с определением наиболее значимых факторов со стороны пациента и типа злокачественного новообразования (ЗНО), определяющих выбор врачей-специалистов.</p></sec><sec><title>Цель исследования</title><p>Цель исследования. Анализ результатов ВДХТ с аутоТГСК у детей с солидными ЗНО группы высокого риска, проведенных в условиях отделения химиотерапии онкогематологических заболеваний и трансплантации костного мозга (ТКМ) для детей ФГБУ «НМИЦ им. В. А. Алмазова».</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Выполнен ретроспективный анализ 55 курсов ВДХТ с аутоТГСК, проведенных в период с 2017 года по 2020 год у 39 пациентов с ЗНО группы высокого риска. Токсичность и эффективность метода оценивалась с учетом частоты инфекционных осложнений, ранней посттрансплантационной летальности, бессобытийной (БСВ) и общей выживаемости (ОВ).</p></sec><sec><title>Результаты</title><p>Результаты. Преобладающей категорией пациентов были дети с опухолями ЦНС (61,5 %). Средний возраст больных составил 2 года 9 месяцев. На момент проведения ВДХТ 35,9 % пациентов находились в полной ремиссии (ПР), у 64,1 % сохранялись признаки активной болезни (АБ). У 59 % пациентов был проведен один курс ВДХТ, у 41 % выполнена тандемная трансплантация, согласно рекомендациям протокола лечения основного заболевания. Наиболее частым режимом кондиционирования был карбоплатин+этопозид (27,3 %). В качестве основного источника гемопоэтических стволовых клеток (ГСК) использовались периферические стволовые клетки (87,3 %). Частота развития инфекционных осложнений в посттрансплантационном периоде составила 100 %, преобладали нейтропенический энтероколит (61,8 %) и фебрильная нейтропения (34,5 %). Отмечена высокая частота реактивации ЦМВ-инфекции (25,4 %), из них в 35,7 % случаев имела место ЦМВ-болезнь. Наиболее важным прогностическим фактором был статус заболевания на момент проведения ВДХТ, при этом 2-летняя ОВ составила 85,7 % и 65,3 %, а БСВ 85,7 % и 39 % в группах пациентов с ПР и АБ соответственно. После завершения этапа ВДХТ с аутоТГСК у 94,8 % пациентов была продолжена противоопухолевая терапия.</p></sec><sec><title>Заключение</title><p>Заключение. Метод ВДХТ с аутоТГСК демонстрирует удовлетворительный профиль токсичности и может улучшать показатели ОВ и БСВ у детей с ЗНО группы высокого риска. Достоверным фактором прогноза, определяющим эффективность метода, является статус основного заболевания на момент ВДХТ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. One of the possible options to intensify therapy in patients with high-risk malignant tumors is high-dose chemotherapy (HDCT) with autologous hematopoetic stem cell rescue. However, this method has a high risk of acute and delayed toxicity, and, sometimes doesn’t meet the expected effectiveness. This confirms the necessity of more considerate approach for choosing the category of patients for this therapeutic option with the determination of the most significant factors on the part of the patient and the type of malignant tumor.</p></sec><sec><title>Objective</title><p>Objective. Analysis of the results of HDCT with autologous hematopoetic stem cell transplantation (HSCT) in children with high-risk solid malignancies, conducted in the Department of pediatric oncohematology and BMT of the Federal State Budgetary Institution “V.A. Almazov National Medical Research Center”.</p></sec><sec><title>Design and methods</title><p>Design and methods. We perform a retrospective analysis of 55 cycles of HDCT with autologous hematopoetic stem cell rescue provided from 2017 to 2020 in 39 patients with high-risk malignant tumors. The toxicity and efficacy of the method were assessed taking into account the frequency of infectious complications, early post-transplant mortality, event-free (EFS) and overall survival (OS).</p></sec><sec><title>Results</title><p>Results. The predominant category of patients were children with CNS tumors (61.5 %). Mean age of the patients was 2 years 9 months. At the time of HDCT 35.9% of patients were in complete remission (CR), 64.1 % had signs of active disease (AD). In 59% of patients, one course of HDCT was performed, in 41 % — tandem transplantation was performed according to the recommendations of the protocol for the treatment of the disease. The most common conditioning regimen was carboplatin + etoposide (27.3 %). The predominant source of hematopoietic stem cells were peripheral stem cells (87.3 %). The frequency of infectious complications in the post-transplant period was 100 %, neutropenic enterocolitis (61.8 %) and febrile neutropenia (34.5 %) were predominant. A high frequency of reactivation of CMV infection (25.4 %) was noted, meanwhile CMV disease occurred in 35.7 % of cases. The most important prognostic factor was the disease status at the time of HDCT. 2-year OS incidence of 85.7 % vs 65.3% and EFS 85.7 % vs 39 % in patients with CR and AD respectively. After completing the course of HDCT with autologous HSCT 94.8 % of patients continued anticancer therapy.</p></sec><sec><title>Conclusion</title><p>Conclusion. HDCT with autologous HSCT demonstrates a satisfactory toxicity profile and can improve OS and EFS in children with high-risk malignant tumors. A reliable prognostic factor that determines the effectiveness of the method is the disease status at the time of HDCT.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>аутологичная трансплантация гемопоэтических стволовых клеток</kwd><kwd>высокодозная химиотерапия</kwd><kwd>группа высокого риска</kwd><kwd>детская онкология</kwd><kwd>опухоли головного мозга</kwd><kwd>опухоли центральной нервной системы</kwd><kwd>солидные опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>autologous hematopoetic stem cell rescue</kwd><kwd>brain tumors</kwd><kwd>central nervous system tumors</kwd><kwd>high-dose chemotherapy</kwd><kwd>high-risk group</kwd><kwd>paediatric oncology</kwd><kwd>solid tumors</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации (соглашение № 075-15- 2020-901)</funding-statement><funding-statement xml:lang="en">This work was financially supported by the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-15- 2020-901)</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">Porrata LF, Adjei AA.
