Акромегалия – редкое заболевание, связанное с гиперпродукцией инсулиноподобного фактора роста 1 вследствие наличия у пациента аденомы гипофиза. Для таких пациентов лечение 1‑й линии – хирургическое удаление образования с целью нормализации гормонального статуса. Хирургическое лечение может быть неэффективным по следующим причинам: опухоли больших размеров (по данным магнитно‑резонансной томографии головного мозга), высокие показатели уровня инсулиноподобного фактора роста 1 до операции, инвазии опухоли в кавернозный синус. Поиск новых предикторов рецидива опухолей остается актуальной проблемой.</p><p>Цель исследования – обнаружение новых маркеров агрессивного течения опухолей гипофиза.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы.

Такие интраоперационные характеристики аденомы гипофиза, секретирующей соматотропный гормон, как багрово‑серый цвет солидного компонента, высокая васкуляризация, а также плотно‑эластичная консистенция опухоли, могут рассматриваться как факторы высокого риска в отношении продолженного роста опухоли в первые 6 мес после хирургического лечения или рецидива заболевания в течение года наблюдения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Acromegaly is a rare disease associated with insulin‑like growth factor 1 hyperproduction due to the presence of pituitary adenoma in the patient. The first‑line treatment of such patients is surgical removal of the formation in order to normalize hormonal status. The main predictors of the ineffectiveness of surgical treatment and relapse of the disease are large tumor size, tumor invasion into the cavernous sinus, and high preoperative levels of growth hormone, as well as Ki‑6 % expression. The search for additional risk factors for disease recurrence, which according to various sources is approximately 30 % after primary surgical treatment, is an urgent task for researchers. In our work, we studied the intraoperative characteristics of the tumor, size of pituitary adenomas according to preoperative magnetic resonance imaging of the brain, degree of invasion of the tumor into the cavernous sinus according to the Knosp classification and compared them with disease outcomes after a year of follow‑up after surgical treatment.</p></sec><sec><title>Aim</title><p>Aim. To identify new markers of aggressive progression of pituitary tumors.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. A retrospective analysis of medical documentation, protocols of operations of 90 patients aged between 19 and 73 years with the diagnosis of growth hormone‑secreting pituitary adenoma was performed. The dia gnosis was confirmed based on clinical picture, laboratory and instrumental examination methods. All patients underwent endoscopic transsphenoidal removal of pituitary adenoma by one surgeon in one medical institution between 2017 and 2019.</p></sec><sec><title>Results</title><p>Results. Intraoperative characteristics of the tumor, such as the color of the solid component, density, degree of vascularization were compared with the results of laboratory and instrumental data, as well as the results of surgical treatment after a year of follow‑up.</p></sec><sec><title>Conclusion</title><p>Conclusion. Such intraoperative characteristics of growth hormone‑secreting pituitary adenomas as the purplish‑gray color of the solid component, high vascularization, as well as dense‑elastic consistency of the tumor, can be considered high risk factors for continued tumor growth in the first 6 months after surgical treatment or relapse of the disease during a year of follow‑up.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>акромегалия</kwd><kwd>транссфеноидальная хирургия</kwd><kwd>рецидив акромегалии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acromegaly</kwd><kwd>transsphenoidal surgery</kwd><kwd>recurrence of GH‑secreting adenomas</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">Fleseriu M., Biller B.M.K., Freda P.U. et al.
