Актуальными вопросами остаются оптимизация использования метода у детей раннего возраста в аспектах повышения эффективности и снижения рисков ассоциированных осложнений. В статье представлен одноцентровой ретроспективный анализ аферезов СКПК у детей с онкологическими заболеваниями. В исследование включены 97 пациентов, которым выполнено 138 аферезов СКПК. Медиана возраста составила 2 года 11 месяцев, медиана массы тела – 16,05 кг. Мобилизацию СD34+ клеток проводили филграстимом, в 2 случаях использовали плериксафор. Ко дню афереза медиана числа CD34+ клеток составила 100,5 (10,5–1032) клеток/мкл. Абсолютное число CD34+ клеток в результате 1 сеанса варьировала от 0,38 до 71,91, медиана – 4,8·106/кг. Факторами, влияющими на эффективность афереза СКПК, были меньшая масса тела (р=0,039), меньшее количество курсов предшествующей противоопухолевой терапии (р=0,002), большее число ГСК (CD34/45) в 1 мкл периферической крови по результатам мобилизации (р=0,001). Осложнений, связанных с процедурой афереза, зафиксировано не было. Адекватная подготовка и должный объем сопроводительной терапии с учетом прогнозирования всех рисков позволяет предотвратить осложнения и выполнить аферез СКПК с удовлетворительным результатом.</p></abstract><trans-abstract xml:lang="en"><p>Peripheral blood stem cell apheresis (PBSC) is an effective and safe method of collecting hematopoietic stem cells (HSC) in patients with malignant neoplasms (MN) for subsequent high-dose chemotherapy (HDCT) with autologous hematopoietic stem cell transplantation (auto-HSCT) compared to myeloexfusion. Optimization of the method for young children in terms of increasing efficiency and reducing the risks of associated complications remains a challenge. The article presents a single-center retrospective analysis of PBSC apheresis in children with cancer. The study included 97 patients who underwent 138 PBSC apheresis. The median age was 2 years 11 months, the median body weight was 16.05 kg. Mobilization of CD34+ cells was performed with filgrastim, in 2 cases with plerixafor. By the day of apheresis, the median CD34+ cell count was 100.5 (10.5–1032) cells/µl. The absolute CD34+ cell count as a result of 1 session ranged from 0.38 to 71.91, the median was 4.8·106/kg. Factors influencing the efficiency of PBSC apheresis were lower body weight (p=0.039), fewer courses of previous antitumor therapy (p=0.002), and a higher number of HSCs (CD34+/45+) in 1 µl of peripheral blood based on the mobilization results (p=0.001). There were no complications associated with the apheresis procedure. Adequate preparation and the proper concomitant therapy, taking into account the prediction of all risks, allow preventing complications and performing PBSC apheresis with a satisfactory result.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>онкологические заболевания</kwd><kwd>высокодозная химиотерапия</kwd><kwd>аутоТГСК</kwd><kwd>аферез</kwd><kwd>гемопоэтические стволовые клетки</kwd><kwd>мобилизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>oncological diseases</kwd><kwd>high-dose chemotherapy</kwd><kwd>autoHSCT</kwd><kwd>apheresis</kwd><kwd>hematopoietic stem cells</kwd><kwd>mobilization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования Российской Федерации (соглашение № 075-15-2022-301).</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 № 075-15-2022-301).</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">Sergeenko K.
