Рак яичника – одна из самых агрессивных злокачественных опухолей женской репродуктивной системы, отличающаяся высокой смертностью и сложностью раннего выявления. На начальных стадиях рак яичника, как правило, протекает бессимптомно, что затрудняет его диагностику до момента, когда заболевание достигает продвинутых клинических стадий.</p></sec><sec><title>Ц е л ь</title><p>Ц е л ь . Продемонстрировать клинико-морфологические и прогностические особенности рака яичника с иммуногистохимической экспрессией CD117.</p><p>М а т е р и а л ы и м е т о д ы . Проведен анализ различных литературных источников, рассматривающих проблему рака яичника, ассоциированного с экспрессией CD117. Для поиска литературы использованы базы данных PubMed, Scopus, Research Square и Web of Science. В обзор включены статьи, опубликованные с 2021 по 2024 годы.</p></sec><sec><title>Р е з у л ь т а т ы</title><p>Р е з у л ь т а т ы . Анализ данных научной литературы подтвердил значимость высокого уровня экспрессии CD117 в опухолевых клетках в сочетании с другими иммуногистохимическими маркерами, характерными для серозного рака яичника высокой степени злокачественности (SOX2, COT4 и NANOG). Активация CD117 при раке яичников приводит к активации нисходящих сигнальных путей, с вовлечением генов: RAS/ERK, PI3K, SRC, JAK/ STAT, Wnt и Notch, в результате которой формируются популяции раковых стволовых клеток, обусловливая высокий агрессивный биологический потенциал опухоли.</p></sec><sec><title>З а к л ю ч е н и е</title><p>З а к л ю ч е н и е . Высокая экспрессия CD117 связана с неблагоприятным прогнозом, более агрессивным течением заболевания и склонностью к метастазированию.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>I n t r o d u c t i o n</title><p>I n t r o d u c t i o n . Ovarian cancer is one of the most aggressive malignant tumors of the female reproductive system, characterized by high mortality and difficulty in early detection. At the early stages, ovarian cancer is usually asymptomatic, which complicates its diagnosis until the disease reaches advanced clinical stages.</p></sec><sec><title>A i m</title><p>A i m . To demonstrate the clinical, morphological and prognostic features of ovarian cancer with CD117 expression.</p><p>M a t e r i a l s a n d m e t h o d s . An analysis of various literature sources considering the problem of ovarian cancer associated with CD117 expression was performed. PubMed, Scopus, Research Square and Web of Science databases were used to search for literature. The review includes articles published from 2021 to 2024.</p></sec><sec><title>R e s u l t s</title><p>R e s u l t s . The analysis of the literature data confirmed the presence of high CD117 expression in tumor cells in combination with other immunohistochemical markers characteristic of high-grade serous ovarian cancer (SOX2, COT4, and NANOG). CD117 activation in ovarian cancer leads to activation of downstream signaling pathways involving the genes: RAS/ERK, PI3K, SRC, JAK/STAT, Wnt, and Notch, resulting in the formation of cancer stem cell populations, which determines high aggressiveness of the tumor.</p></sec><sec><title>C o n c l u s i o n</title><p>C o n c l u s i o n . High expression of CD117 is associated with poor prognosis, more aggressive disease progression and tendency to metastasizing.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичника</kwd><kwd>CD117 (c-kit)</kwd><kwd>раковые стволовые клетки (РСК)</kwd><kwd>диагностика и прогноз</kwd><kwd>иммуногистохимическое исследование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>CD117 (c-kit)</kwd><kwd>cancer stem cells (CSC)</kwd><kwd>diagnosis and prognosis</kwd><kwd>immunohistochemical study</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">Frąszczak K., Barczyński B.
