In the current issue international practices and own experience in relapsed/refractory pediatric NHL are presented: lymphoblastic lymphomas, anaplastic large cell lymphoma, and heterogeneous group of mature B-cell lymphomas. Chemotherapy protocols, results of nelarabine, rituximab, crizotinib, brentuximab vedotin, stem cell transplantation use for relapsed/refractory pediatric NHL treatment are presented. In 27 relapsed NHL patients treated inN.N.BlokhinNationalMedicalResearchCenterof Oncology, overall survival was 29.1 ± 7.9% (median follow-up 56.3 ± 14.4 months). Primary refractory NHL cases were fatal. Own and literature data make it necessary further study of new therapeutic approaches aimed at improvement of results in relapsed/refractory NHL.</p></abstract><trans-abstract xml:lang="ru"><p>Несмотря на разработку и активное использование современных высокоэффективных протоколов лечения неходжкинских лимфом (НХЛ) у детей, результаты терапии рецидивов и рефрактерных форм остаются неудовлетворительными. В настоящей статье приведен мировой и собственный опыт лечения рецидивов/рефрактерных форм различных вариантов НХЛ у детей: лимфобластных лимфом из клеток-предшественников, анапластической крупноклеточной лимфомы и гетерогенной группы лимфом из зрелых В-клеток. Представлены противорецидивные схемы лечения, результаты использования неларабина, ритуксимаба, кризотиниба, брентуксимаба ведотина, трансплантации гемопоэтических стволовых клеток в лечении рецидивов и рефрактерных форм НХЛ. При анализе терапии рецидивов 27 больных с НХЛ, проходивших лечение в ФГБУ «НМИЦ онкологии им. Н.Н. Блохина» МЗ РФ, показатель общей выживаемости составил 29,1 ± 7,9 % (медиана наблюдения 56,3 ± 14,4 мес). Попытки терапии первично рефрактерного течения НХЛ оказались неудачными. Собственные и литературные данные заставляют проводить дальнейший поиск терапевтических решений, направленных на повышение результатов терапии рецидивов и рефрактерных форм НХЛ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>non-Hodgkin’s lymphomas</kwd><kwd>relapse</kwd><kwd>treatment</kwd><kwd>children</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>неходжкинские лимфомы</kwd><kwd>рецидивы</kwd><kwd>лечение</kwd><kwd>дети</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Valiev T.T., Popa A.V., Levashov A.S. et al.
