The group of children and adolescents received BV is not sufficient yet to assess the effectiveness and toxicity as in adults. In multicenter randomized trials BV was shown to be highly effective in adult patients. Aims: to evaluate the effectiveness and toxicity of anti-relapse therapy with BV followed by hematopoietic stem cell transplantation in children, adolescents and young adults with primary refractory forms of Hodgkin's Lymphoma (HL) and in patients with relapses of the disease. This study was approved by the Independent Ethical Committee and the Academic Council of Dmitriy Rogachev National Medical Research Center of Pediatric Hematology, Oncology, Immunology Ministry of Healthcare of Russian Federation. In the 2012–2019 period 54 patients with primary refractory course and relapses of LH (Hodgkin's Lymphoma) were enrolled, among them 24 (44.4%) boys and 30 (55.6%) girls aged 4 to 25 years at the time of diagnosis of HL (average age-13.84.4 years). Therapy included BV as a part of block BB (brentuximab vedotin, ribomustin, dexamethasone) (n = 44) and BV monotherapy (n = 12). Complete response was achieved for 44 (81.4%) patients (pts) received BV (as a part of block BB - 37 pts and as monotherapy – 7 pts). Seven (12.9%) among 54 patients were transferred to therapy with PDL1 inhibitors (nivolumab, pembrolizumab) due to progression/refractoriness. Three (5.7%) patients were lost from observation. In our study, toxicity was observed in 7.4% of patients (n = 4) received brentuximab as a part of block BB: grade 4 hematological toxicity (n = 3) and infectious complications in the form of mucositis (n = 1). There was no evidence of any toxicity among pts received BV as monotherapy. BV in children, adolescents and young adults with primary refractory course and relapses of LH had shown high efficiency, which was not accompanied by significant toxicity.</p></abstract><trans-abstract xml:lang="ru"><p>В рамках международных мультицентровых рандомизированных исследований брентуксимаб ведотин (БВ) показал высокую эффективность у взрослых пациентов с первично-рефрактерными формами и рецидивами лимфомы Ходжкина (ЛХ). Группа населения детского и подросткового возраста, получавшая БВ, пока недостаточно велика для того, чтобы сделать выводы об эффективности и токсичности этого препарата. Цель работы: оценить результаты противорецидивной терапии препаратом БВ с последующей трансплантацией гемопоэтических стволовых клеток у детей, подростков и молодых взрослых с первично-рефрактерными формами ЛХ и у пациентов с рецидивами заболевания. Данное исследование одобрено Независимым этическим комитетом и утверждено решением Ученого совета НМИЦ ДГОИ им. Дмитрия Рогачева Минздрава России. В исследование было включено 54 пациента с первично-рефрактерным течением и рецидивами ЛХ, проходящих терапию, включающую БВ в различных режимах введения: в составе блока ВВ (n = 42) или в монотерапии (n = 12), в НМИЦ ДГОИ им. Дмитрия Рогачева Минздрава России в период с 2012 по 2019 год. Среди этих пациентов 24 (44,4%) мальчика и 30 (55,6%) девочек в возрасте от 4 до 25 лет на момент постановки диагноза ЛХ (средний возраст – 13,8 ± 4,4 года). Полный ответ был достигнут у 44 (81,4%) пациентов, получавших БВ (37 человек – блок ВВ; 7 – монотерапию БВ). В связи с прогрессией/рефрактерностью ЛХ 7 (12,9%) человек были переведены на терапию ингибиторами PDL1 (ниволумаб, пембролизумаб); 3 (5,7%) пациентов потеряны из-под наблюдения. В нашем исследовании токсичность наблюдалась у 4 (7,4%) пациентов, получавших БВ в составе блока ВВ: гематологическая токсичность 4-й степени (n = 3) и инфекционные осложнения в виде мукозита (n = 1). При использовании БВ в монотерапии нежелательных эффектов не отмечено. Применение БВ у детей, подростков и молодых взрослых с первично-рефрактерным течением и рецидивами ЛХ показало высокую эффективность и не сопровождается значительной токсичностью.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Hodgkin's Lymphoma</kwd><kwd>children</kwd><kwd>relapse</kwd><kwd>primary refractory course</kwd><kwd>treatment methods</kwd><kwd>brentuximab vedotin</kwd><kwd>nivolumab</kwd><kwd>pembrolizumab</kwd><kwd>bendamustin</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>лимфома Ходжкина</kwd><kwd>дети</kwd><kwd>рецидив</kwd><kwd>первично-рефрактерное течение</kwd><kwd>методы лечения</kwd><kwd>брентуксимаб ведотин</kwd><kwd>ниволумаб</kwd><kwd>пембролизумаб</kwd><kwd>бендамустин</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Siddiqi T., Thomas S.H., Chen R.
