Молекулярные изменения, ассоциированные с возрастом, определяют терапевтические подходы, которые, в свою очередь, влияют на процессы рецидивирования. Обсуждается два основных механизма рецидивирования: прогрессия доминантного аллеля драйверной мутации и эволюция клонального состава, инициируемая схемами химиотерапии. Представлена оценка вклада эпигенетических механизмов в прогрессию опухоли как способа формирования химиорезистентности и эволюционно устойчивых клонов, а также роль аберрантного метилирования как самостоятельного функционального механизма с учётом изменения мутационного спектра рецидивирующей опухоли. </p></abstract><trans-abstract xml:lang="en"><p>The work highlights the variability of the mutational profile and clonal evolution of AML from diagnosis to relapse, with an emphasis on pediatric AML. The significance of molecular changes associated with age determines therapeutic approaches, which, in turn, influence the processes of relapse. Two main mechanisms of relapse are discussed: progression of the dominant allele of the driver mutation and evolution of clonal composition initiated by chemotherapy regimens. The contribution of epigenetic mechanisms in tumor progression as a way of forming chemoresistance and evolutionarily stable clones is assessed. As well as the role of aberrant methylation as an independent functional mechanism, taking into account the change in the mutational spectrum of a recurrent tumor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>острый миелоидный лейкоз</kwd><kwd>ОМЛ</kwd><kwd>клональная эволюция</kwd><kwd>эпигенетическая регуляция</kwd><kwd>рецидив</kwd><kwd>мутации  I/II типов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acute myeloid leukemia</kwd><kwd>AML</kwd><kwd>clonal evolution</kwd><kwd>epigenetic regulation</kwd><kwd>relapse</kwd><kwd>mutations of types I/II</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Минобрнауки России для ФГБНУ «МГНЦ» на 2024 г.</funding-statement><funding-statement xml:lang="en">The study was carried out according to the state assignment of the Ministry of Science and Higher Education of the Russian Federation    for the Research Centre for Medical Genetics.</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">Pediatric Acute Myeloid Leukemia (AML): From Genes to Models Toward Targeted Therapeutic Intervention.
