Favorable dosimetric characteristics of stereotactic radiation techniques justify the use of such treatments for local radiation control in children with oligometastatic recurrent MB. Given the constant risk of metastatic dissemination and in order to potentiate response to radiation therapy and improve progression-free survival, metronomic molecular-targeted antiangiogenic therapy (MEMMAT, Medulloblastoma European Multitarget Metronomic AntiAngiogenic Trial) can be considered in children with recurrent/progressive MB. Here, we report 2 clinical cases that demonstrate the effectiveness of the treatment approach involving stereotactic irradiation followed by the metronomic MEMMAT regimen for oligometastatic recurrent MB in pediatric patients. The patients’ parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.</p></abstract><trans-abstract xml:lang="ru"><p>Низкие показатели выживаемости детей с рецидивом медуллобластомы (МБ) диктуют необходимость поиска терапевтических стратегий, являющихся альтернативными действующим стандартам лечения. Благодаря дозиметрическим характеристикам в целях локального лучевого контроля при олигометастатических рецидивах МБ в педиатрической практике оправдано применение стереотаксических методов облучения. Учитывая сохраняющийся риск метастатической диссеминации, для потенцирования достигаемого облучением ответа и улучшения выживаемости без прогрессии может быть рассмотрена метрономная и молекулярнонаправленная антиангиогенная терапия для детей с рецидивирующей/прогрессирующей МБ MEMMAT (Medulloblastoma European Multitarget Metronomic Anti-Angiogenic Trial). Целью работы является описание 2 клинических случаев, демонстрирующих эффективность стратегии последовательного применения стереотаксического облучения и метрономного режима МЕММАТ в лечении олигометастатического рецидива МБ у пациентов детского возраста. Родители пациентов дали согласие на использование информации, в том числе фотографий детей, в научных исследованиях и публикациях.</p></trans-abstract><kwd-group xml:lang="en"><kwd>medulloblastoma</kwd><kwd>recurrence</kwd><kwd>children</kwd><kwd>stereotactic irradiation</kwd><kwd>metronomic therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>медуллобластома</kwd><kwd>рецидив</kwd><kwd>дети</kwd><kwd>стереотаксическое облучение</kwd><kwd>метрономная терапия</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">Sabel M., Fleischhack G., Tippelt S., Gustafsson G., Doz F., Kortmann R., et al.; SIOP-E Brain Tumour Group.
