Основным методом лечения является эндоскопическая резекция слизистой (ЭРС), однако в ряде случаев применяется адъювантная терапия аналогами соматостатина (АС). Вопрос об эффективности такого подхода остаётся дискуссионным.</p></sec><sec><title>   Цель</title><p>   Цель: Определить, как назначение АС у больных НЭО желудка 1‑го типа (cT1–2N0M0, Grade I–II) влияет на частоту повторных ЭРС, выполняемых в связи с появлением метахронных опухолевых очагов.</p></sec><sec><title>   Материалы и методы</title><p>   Материалы и методы: Проведено ретроспективное одноцентровое исследование, включавшее пациентов с НЭО желудка 1‑го типа, перенёсших ЭРС в период с 2007 по 2024 годы. Для оценки влияния адъювантной терапии АС сформированы две группы: 1) получавшие АС после ЭРС; 2) динамическое наблюдение без противоопухолевого лечения. Для устранения групповых различий применён метод «псевдорандомизации» (propensity score matching) с использованием “cardinality matching”. Основным критерием эффективности служила частота повторных ЭРС. Статистический анализ выполнен с помощью t‑критерия Стьюдента.</p></sec><sec><title>   Результаты</title><p>   Результаты: В итоговый анализ вошли 104 пациента (52 в каждой группе), сбалансированные по полу, возрасту, Ki67, Grade, TNM‑стадии и другим факторам. Не выявлено статистически значимого снижения частоты повторных ЭРС в группе, получавшей АС, по сравнению с группой динамического наблюдения (р &gt; 0,05). Также не отмечено достоверных различий в количестве выполняемых контрольных гастроскопий (р &gt; 0,05).</p></sec><sec><title>   Выводы</title><p>   Выводы: Назначение аналогов соматостатина в адъювантном режиме у больных НЭО желудка 1‑го типа статистически значимо не влияет на частоту повторных вмешательств. Таким образом, рутинное использование АС для профилактики метахронных очагов после ЭРС представляется нецелесообразным.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>   Background</title><p>   Background: Gastric type 1 neuroendocrine neoplasms (gNENs) are relatively indolent malignancies with low metastatic potential. Endoscopic resection (ER) is considered the primary treatment, while somatostatin analogs (SSAs) have proven anti-secretory and anti-proliferative effects. However, routine adjuvant SSA therapy after ER is not universally recommended.</p></sec><sec><title>   Objective</title><p>   Objective: To determine whether adjuvant therapy with SSAs in patients with type 1 gNENs affects the rate of repeated endoscopic resections due to metachronous lesions.</p></sec><sec><title>   Methods</title><p>   Methods: We conducted a retrospective, single-center study which included patients with gNENs cT1–2N0M0, Grade I–II who underwent ER from 2007 to 2024. Two groups were compared: one received SSAs in the adjuvant setting, the other remained under observation only. Propensity score matching using a “cardinality matching” approach ensured balanced cohorts. The primary endpoint was the frequency of repeated ER. Statistical analyses were performed using Student’s t-test.</p></sec><sec><title>   Results</title><p>   Results: After matching, there was no statistically significant reduction in repeated ER among patients receiving SSAs (p &gt; 0.05). Furthermore, no significant difference in the number of endoscopic examinations was observed between the groups.</p></sec><sec><title>   Conclusion</title><p>   Conclusion: Routine adjuvant SSA therapy after ER does not appear to reduce the frequency of repeated resections in patients with type 1 gastric NENs, suggesting that such practice may be unnecessary.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>нейроэндокринные опухоли желудка</kwd><kwd>аналоги соматостатина</kwd><kwd>опухоли желудка</kwd><kwd>нейроэндокринные неоплазии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric neuroendocrine tumors</kwd><kwd>somatostatin analogs</kwd><kwd>gastric tumors</kwd><kwd>neuroendocrine neoplasms</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья подготовлена без спонсорской поддержки</funding-statement><funding-statement xml:lang="en">The article was prepared without sponsorship</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">Fortin S.P., Johnston S.S., Schuemie M.J.
