Clinical manifestations of the disease vary and depend on the patient’s age. One of the most common complications of neurofibromatosis type 1 is plexiform neurofibroma – a benign tumor affecting peripheral nerves. For a long time, there had been no standard care for such patients in the Russian Federation; treatment of plexiform neurofibromas was usually limited to symptomatic therapy and repeated surgical interventions. In the last few years, treatment approach to patients with neurofibromatosis type 1 complicated by plexiform neurofibromas changed, since a targeted drug, selumetinib became available. In clinical trials, 65 % of children receiving selumetinib demonstrated a partial response (reduction in the volume of plexiform neurofibromas by 20 % or more) for more than 3 cycles (months), 56 % of children demonstrated a long-term response (a year or more) without traumatic surgical interventions. In our country, more than 200 children have already received selumetinib under the early access program after its registration in the Russian Federation (January 2021). In Yu.E. Veltischev Research and Clinical Institute for Pediatrics and Pediatric Surgery, the drug was prescribed to 104 patients; of them, 54 patients were followed up between April 2021 and October 2023. The most common adverse events associated with selumetinib in our patients included skin rash (acne/maculopapular rash or eczema), dry skin, hair discoloration and hair loss, paronychia, and an asymptomatic elevation of creatine phosphokinase. This article provides information on the most common adverse events of selumetinib therapy, preventive measures, and recommendations for patient follow-up.</p></abstract><trans-abstract xml:lang="ru"><p>Нейрофиброматоз 1-го типа – мультисистемное генетическое заболевание, предрасполагающее к развитию доброкачественных и злокачественных опухолей, обусловленное мутациями гена <italic>NF1.</italic> Клинические проявления заболевания разнообразны и носят возрастзависимый характер. Одним из наиболее частых осложнений нейрофиброматоза 1-го типа является развитие доброкачественных опухолей периферических нервов – плексиформных нейрофибром. стандартов оказания медицинской помощи пациентам с нейрофиброматозом в РФ ранее не было, и лечение его осложнений, плексиформных нейрофибром, ограничивалось лишь симптоматической терапией и повторными хирургическими вмешательствами. В последние несколько лет подход к лечению пациентов с нейрофиброматозом 1-го типа, осложненным плексиформными нейрофибромами, изменился благодаря возможности применения таргетного препарата селуметиниба. В клинических исследованиях у 65 % пациентов детского возраста был достигнут частичный ответ (уменьшение объема плексиформных нейрофибром на 20 % и более) более 3 циклов (месяцев), у 56 % – длительный ответ на терапию (год и более) без применения травмирующих хирургических вмешательств. В нашей стране по программе раннего доступа и после регистрации в РФ (с января 2021 г. и по настоящее время) селуметинибом были обеспечены более 200 детей. В Научно-исследовательском клиническом институте педиатрии и детской хирургии им. акад. ю.е. Вельтищева препарат был назначен 104 пациентам, из них под динамическим наблюдением в период с апреля 2021 г. по октябрь 2023 г. находилось 54 пациента. Наиболее частыми нежелательными явлениями на фоне приема селуметиниба у наших пациентов были кожная сыпь (угревидная сыпь/макуло-папулезные или экзематозные высыпания), сухость кожи, изменение цвета и выпадение волос, паронихии и бессимптомное повышение уровня креатинфосфокиназы. В статье представлена информация по основным нежелательным явлениям селуметиниба и мерам их возможной профилактики, даны рекомендации по динамическому наблюдению пациентов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>neurofibromatosis type 1</kwd><kwd>plexiform neurofibromas</kwd><kwd>selumetinib</kwd><kwd>adverse events</kwd><kwd>toxicity control</kwd><kwd>prevention of complications</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>нейрофиброматоз 1-го типа</kwd><kwd>плексиформные нейрофибромы</kwd><kwd>селуметиниб</kwd><kwd>нежелательные явления</kwd><kwd>контроль токсичности</kwd><kwd>профилактика осложнений</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">Instructions for medical use of the drug Koselugo® (selumetinib) LP-007563 dated November 1, 2021.</mixed-citation><mixed-citation xml:lang="ru">Инструкция по медицинскому применению лекарственного препарата Коселуго® (селуметиниб) ЛП-007563 от 01.11.2021.</mixed-citation></citation-alternatives></ref><ref id="B2"><label>2.</label><citation-alternatives><mixed-citation xml:lang="en">2.
