В обзоре рассматриваются применяемые в настоящее время иммуногистохимические и циркулирующие маркеры для ее диагностики, обсуждаются чувствительность и специфичность данных параметров. Вместе с тем подчеркивается актуальность поиска новых биохимических показателей наличия инсулиномы и ее характеристик, а также изучения механизмов опухолевого роста и гормональной гиперсекреции. Одним из первостепенных методов решения данных задач является иммуногистохимическое тестирование с определением циркулирующих маркеров. Приводятся результаты последних исследований альтернативных секреторных продуктов, в частности, кокаин- и амфетамин-регулируемого транскрипта (CART), хромогранина В, нейроэндокринного секреторного протеина 55 (NESP55). Кроме того, рассматривается вопрос экспрессии различных рецепторов в ткани инсулиномы, в том числе в контексте определения молекулярных мишеней для ее визуализации или радиотерапии. В частности, охарактеризована экспрессия рецепторов к глюкагоноподобному пептиду 1 в ткани опухоли. Уточняется возможная роль рецепторов к мелатонину МТ1 (MTNR1a) и МТ2 (MTNR1b) в патогенезе инсулиномы. Также в статье обсуждается возможное применение опухолевого протеина D52 (TPD52) в качестве нового прогностического биомаркера для дифференциальной диагностики доброкачественной и злокачественной инсулиномы.</p></abstract><trans-abstract xml:lang="en"><p>Insulinoma is the most common functioning pancreatic neuroendocrine tumor. The review examines the currently used immunohistochemical and circulating markers for its diagnosis, and discusses the sensitivity and specificity of these parameters. At the same time, the relevance of searching for new biochemical indicators of the presence of insulinoma and its characteristics, as well as studying the mechanisms of tumor growth and hormonal hypersecretion is emphasized. One of the primary methods for solving these problems is immunohistochemical testing with the determination of circulating markers. The results of recent studies of alternative secretory products, in particular, cocaine - and amphetamine - regulated transcript (CART), chromogranin B, and neuroendocrine secretory protein 55 (NESP55) are presented. In addition, the question of expression of various receptors in the insulinoma tissue is considered, including in the context of determining molecular targets for its visualization or radiotherapy. In particular, the expression of receptors for glucagon-like peptide 1 in the tumor tissue is characterized. The possible role of melatonin receptors MT1 (MTNR1a) and MT2 (MTNR1b) in the pathogenesis of insulinoma is clarified. The article also discusses the possible use of tumor protein D52 (TPD52) as a new predictive biomarker for the differential diagnosis of benign and malignant insulinoma.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>инсулинома</kwd><kwd>нейроэндокринная опухоль</kwd><kwd>иммуногистохимия</kwd><kwd>биомаркеры</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Insulinoma</kwd><kwd>neuroendocrine tumor</kwd><kwd>immunohistochemistry</kwd><kwd>biomarkers</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа проведена в рамках выполнения государственного задания «Наследственные опухолевые синдромы и множественные эндокринные неоплазии: персонализация диагностики и лечения, прогнозирование рисков, идентификация ядерных семей» на 2018–2020 гг.</funding-statement><funding-statement xml:lang="en">The work was carried out within the framework of the state assignment "Hereditary tumor syndromes and multiple endocrine neoplasias: personalization of diagnosis and treatment, risk prediction, identification of nuclear families" for 2018–2020.</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">Giovanella LC.
