В статье представлен анализ частоты развития вторичных опухолей после проведения терапии лимфомы Ходжкина (ЛХ) у 508 пациентов в возрасте 0–18 лет в Республике Беларусь.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Пациенты получали программную терапию в рамках протокола DAL-HD-90(m). Сроки наблюдения составили от 10 мес до 25 лет. За весь период наблюдения у 26 (4,1 %) пациентов было диагностировано 27 вторичных злокачественных опухолей (ВО): рак щитовидной железы – 11 (40,7 %), рак желудка – 2 (7,4 %), рак верхнедолевого бронха – 1 (3,7 %), карцинома околоушной слюнной железы – 2 (7,4 %), рак молочной железы – 1 (3,7 %), гепатоцеллюлярный рак печени – 1 (3,7 %), саркома мягких тканей – 2 (7,4 %), почечно-клеточный рак – 1 (3,7 %), опухоль яичника – 1 (3,7 %), базальноклеточный рак кожи – 2 (7,4 %), острый миелоидный лейкоз – 2 (7,4 %), миелодиспластический синдром – 1 (3,7 %). Все случаи ВО системы крови были с летальным исходом.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что солидные ВО развивались в пределах области лучевого воздействия на органы и ткани. Риск развития ВО у пациентов с ЛХ усиливался с увеличением времени наблюдения после окончания лечения. Совокупная частота ВО составила 3,4 ± 0,8 % через 10 лет, 4,6 ± 1,0 % через 15 лет и 7,0 ± 1,6 % через 20 лет после постановки диагноза ЛХ. Латентный период развития ВО после ЛХ – 8,4 года (от 5 мес до 23 лет).</p></sec><sec><title>Выводы</title><p>Выводы. Полученные данные подтверждают необходимость оптимизации объемов лечения, уменьшения доз и сокращения показаний к лучевой терапии (ЛТ) с учетом прогностических факторов, внедрения новых методик ЛТ и использования новых схем лечения пациентов детского возраста с ЛХ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. The article analyzes the incidence of secondary malignant tumors (SMT) after therapy of Hodgkin’s lymphoma (HL) in 508 patients aged 0–18 years in the Republic of Belarus.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Patients received program therapy under the DAL-HD-90(m) protocol. The observation period is from 10 months to 25 years. During the entire follow-up period, 27 secondary malignant tumors were diagnosed in 26 (4.1 %) patients: thyroid cancer – 11 (40.7 %), acute myeloid leukemia – 2 (7.4 %), stomach cancer – 2 (7.4 %), upper lobe bronchus cancer – 1 (3.7 %), parotid salivary gland carcinoma – 2 (7.4 %), breast cancer – 1 (3.7 %), hepatocellular liver cancer – 1 (3.7 %), soft tissue sarcoma – 2 (7.4 %), renal cell carcinoma – 1 (3.7 %), ovarian tumor – 1 (3.7 %), myelodysplastic syndrome – 1 (3.7 %), basal cell skin cancer – 2 (7.4 %). All cases of secondary hematological tumors were fatal.</p></sec><sec><title>Results</title><p>Results. It was found that solid SMT developed within the area of radiation exposure to organs and tissues. The risk of developing SMT in patients with HL increases with increasing follow-up time after treatment. The cumulative incidence of SMT was 3.4 ± 0.8 % after 10 years, 4.6 ± 1.0 % after 15 years, and 7.0 ± 1.6 % 20 years after the diagnosis of HL. The latent period of SMT development after HL was 8.4 years (from 5 months to 23 years).</p></sec><sec><title>Conclusion</title><p>Conclusion. The data confirmed the need to optimize the therapy volume, reduce doses and indications for radiation therapy (RT), consider prognostic factors, introduce new RT methods, and use new treatment regimens for children with HL.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>лимфома Ходжкина</kwd><kwd>дети</kwd><kwd>подростки</kwd><kwd>химиолучевое лечение</kwd><kwd>протокол DAL-HD-90(m)</kwd><kwd>отдаленные последствия</kwd><kwd>вторичные опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Hodgkin’s lymphoma</kwd><kwd>children</kwd><kwd>adolescents</kwd><kwd>chemoradiotherapy</kwd><kwd>DAL-HD-90(m) protocol</kwd><kwd>long-term complications</kwd><kwd>secondary malignant tumors</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mauz-Körholz C., Metzger M.L., Kelly K.M., Schwartz C.L., Castellanos M.E., Dieckmann K., Kluge R., Körholz D.
