Метотрексат является одним из основных противоопухолевых препаратов из группы антиметаболитов, входящих в 1-ю линию терапии остеосаркомы. Препарат используется в дозе 12 г/м2 согласно протоколу EURAMOS-1. Спектр метотрексат-индуцированных осложнений включает в себя нефротоксичность, гепатотоксичность, миелосупрессию, поражение слизистых оболочек и кожи, диспепсические расстройства. Одним из грозных, но обратимых осложнений является метотрексат-индуцированная транзиторная энцефалопатия (МИЭ), клинические проявления которой встречаются более чем у 15 % больных, в лечении которых используются высокие дозы метотрексата.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В НИИ ДОиГ им. акад. РАМН Л.А. Дурнова ФГБУ «НМИЦ онкологии им. Н.Н. Блохина» Минздрава России в период с 2013 по 2023 г. зафиксировано 10 случаев МИЭ. Все пациенты получали терапию согласно протоколу EURAMOS-1. У 4 из 10 больных после проведенного курса химиотерапии отмечалось замедление скорости выведения высокодозного метотрексата (HD MTX). Электролитных нарушений на фоне проведения лечения не зарегистрировано. Медиана возникновения осложнения составила 7 сут (от 5 до 12 сут) от введения метотрексата. Наиболее часто оно развивалось после 3 проведенных курсов с использованием HD MTX в дозировке 12 г/м2 , что соответствует 6 введениям препарата. Неврологические симптомы: головная боль, нарушение зрения, афазия, судороги носили транзиторный характер и купировались в среднем через 24 ч от начала терапии.</p></sec><sec><title>Результаты</title><p>Результаты. Всем 10 пациентам в качестве лечения МИЭ проводились обязательная алкализация, массивная инфузионная терапия, применялись нейропротективные препараты, а также противоотечная терапия. В дальнейшем 9 из 10 пациентов продолжили курс лечения с применением метотрексата.</p></sec><sec><title>Выводы</title><p>Выводы. Стандартных рекомендаций по терапии МИЭ в настоящее время не существует. Однако развитие тяжелой нейротоксичности не исключает возможности дальнейшего применения HD MTX в программе лечения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Methotrexate is one of the main chemotherapeutic agents of group antimetabolits, includes in the first line of therapy against osteosarcoma. The drug uses in dose 12 g/m2 according to the protocol EURAMOS-1. The range of methotrexate-induced complications includes renal toxity, hepatotoxicity, myelosuppression, skin and mucosal ulcerations, dyspeptic disorders. One of the formidable, but reversible complications, is methotrexate-induced transient encephalopathy (MIE), the clinical manifestations of which occur in more than 15 % of patients in the treatment of which high doses of methotrexate (HD MTX) are used.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. At the Research Institute of Pediatric Oncology and Hematology named after Academician of the Russian Academy of Medical Sciences L.A. Durnov at N.N. Blokhin National Medical Research Center of Oncology, Ministry of Health of Russia the period from 2013 to 2023 10 cases of MIE were recorded. All patients received therapy according to the protocol EURAMOS-1. The 4 out of 10 patients had a delay in the rate of elimination of HD MTX after the course of chemotherapy. No one patient had electrolyte disturbances with using HD MTX. The median occurrence of the complication’s emerging was 7 days (from 5 to 10 from the start of therapy) and most often developed after 3 courses of methotrexate 12 g/m2 , which corresponds in total 6 doses of methotrexate. Neurological symptoms: headache, visual impairment, aphasia, convulsions were transient and resolved after an average of 24 hours from the start of the treatment.</p></sec><sec><title>Results</title><p>Results. All 10 patients received obligatory alkalization, massive infusion therapy, neuroprotective drugs, as well as decongestant therapy as a treatment of MIE. Subsequently, therapy with methotrexate was continued for the 9 of 10 patients.</p></sec><sec><title>Conclusions</title><p>Conclusions. The standard recommendations for the treatment of MIE do not currently exist. However, the development of severe neurotoxicity does not exclude the possibility of further using of HD MTX in the treatment program</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>остеосаркома</kwd><kwd>метотрексат</kwd><kwd>педиатрия</kwd><kwd>энцефалопатия</kwd><kwd>PRES-синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>osteosarcoma</kwd><kwd>methotrexate</kwd><kwd>pediatrics</kwd><kwd>encephalopathy</kwd><kwd>PRES-syndrome</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">Валиев Т.Т., Шервашидзе М.А., Осипова И.В., Бурлуцкая Т.И., Попова Н.А., Осмульская Н.С., Алескерова Г.А., Сабанцев С.Л., Гордеева З.С., Смирнов В.Ю., Побережная О.А., Юлдашева С.Н., Бабич И.А., Батманова Н.А., Варфоломеева С.Р.
