Изучение редкого спорадического случая метастатической гастриномы, ассоциированной с мутациями в генах MEN1 и TSC2, у мужчины 25 лет.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Был проведен ретроспективный анализ истории болезни пациента 25 лет с наличием спорадической гастриномы с высоко агрессивным клиническим течением и высоким метастатическим потенциалом. Секвенирование ДНК, экстрагированной из  операционного биоптата опухоли, проводили на секвенаторе Illumina NextSeq 550 (Illumina Inc., США) со  средним покрытием не менее 100× с применением таргетной панели AmpliSeq Comprehensive Cancer Panel for  Illumina для исследования экзонных регионов 409 генов, мутации в которых ассоциированы с онкопатологией.</p></sec><sec><title>Результаты</title><p>Результаты. Представлен результат комплексной  диагностики и успешного лечения метастатической гастриномы с применением современных  локорегиональных методов лечения и препаратов из  группы аналогов соматостатина. С помощью секвенирования нового поколения и секвенирования по Сэнгеру в экстрагированной ДНК были выделены спорадические мутации в генах MEN1 и TSC2 с выраженным клиническим значением.</p></sec><sec><title>Заключение</title><p>Заключение. Идентифицированные мутации, являясь  драйверами опухолевого процесса, очевидно, определили  нетипичное развитие представленного клинического случая  – спорадического синдрома Золлингера – Эллисона. Полная морфологическая и иммуногистохимическая  верификация нейроэндокринной опухоли до начала лечения определила его успешную тактику, включавшую  применение аналогов соматостатина в адъювантном и неоадьювантном режимах в сочетании с  химиоэмболизацией печеночных метастазов. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title> Aim</title><p> Aim. To study a rare sporadic case of metastatic gastrinoma associated with mutations in the MEN1 and TSC2 genes in a 25-year-old male.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of the history of a 25-year-old patient with sporadic gastrinoma with a highly aggressive clinical course and high metastatic potential was performed. Sequencing of the DNA  extracted from the surgical tumor biopsy was performed on the Illumina  NextSeq 550 sequencer (Illumina Inc., USA) with the mean coverage of at least 100× using the AmpliSeq target panel for Illumina Comprehensive Cancer Panel for studying exons of 409 genes, mutations in which are associated with oncopathology.</p></sec><sec><title>Results</title><p>Results. The article presents the results of complex diagnosis and treatment of metastatic gastrinoma using modern locoregional therapy and drugs from the group of somatostatin analogues. Using next generation sequencing and Sanger sequencing, sporadic mutations in the MEN1 and TSC2 genes with pronounced clinical significance were identified in the extracted DNA.</p></sec><sec><title>Conclusion</title><p>Conclusion. The identified mutations, being the drivers of the tumor process, apparently determined the atypical development of the presented clinical case – the sporadic Zollinger – Ellison syndrome. Complete morphological and immunohistochemical validation of the neuroendocrine tumor before treatment determined a successful treatment strategy, including the use of somatostatin analogues in adjuvant and neoadjuvant therapies in combination with chemoembolization of hepatic metastases. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейроэндокринная опухоль</kwd><kwd>синдром Золлингера – Эллисона</kwd><kwd>секвенирование нового поколения</kwd><kwd>метастазы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>neuroendocrine tumor</kwd><kwd>Zollinger – Ellison syndrome</kwd><kwd>next generation sequencing</kwd><kwd>metastases</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">Ellison E.C., Johnson J.A.
