This approach has significantly increased the long-term survival rate, but it has been associated with toxicity, requiring supportive care. Factors that predict toxicity were identified, including genes involved in the metabolism (<italic>MTHFR</italic>) or transport (<italic>SLCO1B1</italic>) of methotrexate. The analysis of methotrexate metabolism has identified additional genes responsible for the elimination of this drug, allowing for more effective prevention and treatment of methotrexate-associated toxicity.</p><p><bold>Aim. </bold>To study the genetic polymorphisms of enzymes involved in the methotrexate metabolism and associated toxicity in the treatment of pediatric acute lymphoblastic leukemia and non-Hodgkin’s lymphomas.</p><p><bold>Materials and methods. </bold>Data were analyzed in specialized medical databases such as Pubmed, Scopus, Web of Science, Frontiers, and Google Scholar from 2001 to 2024.</p><p><bold>Results. </bold>The main predictors of high-dose methotrexate-associated toxicity are gene polymorphisms in <italic>MTHFR</italic>, <italic>SLCO1B1</italic>, <italic>ARID5B</italic>.</p><p><bold>Conclusion. </bold>Despite the contradictory data presented in the literature, it is important to consider the detection of polymorphisms during high-dose methotrexate treatment in order to administer timely supportive care and prevent significant toxicity.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Введение.</bold> Большим достижением в лечении высокоагрессивных неходжкинских лимфом и острого лимфобластного лейкоза стало включение в протоколы терапии высокодозного (1000–5000 мг/м2) метотрексата. Подобный подход позволил существенно повысить показатели многолетней выживаемости больных, но оказался сопряжен с токсичностью лечения, требующей проведения сопроводительной терапии. Поиск факторов, которые могли бы предопределить развитие токсичности, позволил выделить гены, участвующие в метаболизме (например, <italic>MTHFR</italic>) или транспорте (<italic>SLCO1B1</italic>) метотрексата. Дальнейший анализ метаболизма метотрексата, определение дополнительных генов, участвующих в элиминации этого препарата, позволят более эффективно профилактировать и лечить токсические осложнения, сопряженные с противоопухолевыми эффектами метотрексата.</p><p><bold>Цель исследования</bold> – изучение генетических полиморфизмов ферментов, участвующих в метаболизме метотрексата, и ассоциированной с ними токсичности при лечении острого лимфобластного лейкоза и неходжкинских лимфом у детей.</p><p><bold>Материалы и методы.</bold> Проведен анализ данных в специализированных медицинских базах PubMed, Scopus, Web of Science, Frontiers, Google Scholar с 2001 по 2024 г.
