Moreover, malignant ovarian tumors, as a rule, are detected only in the late stages of the disease, so ovarian cancer is the main cause of unfavorable and fatal outcomes in gynecological oncology. Accordingly, clinical criteria and instrumental studies are not enough to distinguish the forms of tumors from each other, to assess the possibility of transformation of a borderline tumor into a malignant one, as well as to determine the stage of development of the tumor process, therefore, genetic markers of transformation of borderline ovarian tumors into highly differentiated ovarian cancer are used and studied for diagnostic purposes. This paper provides information on genetic markers of the transformation of borderline ovarian tumors into highly differentiated ovarian cancer. Based on the analysis of literature data, it was analyzed that mutational changes in genes such as BRAF, KRAS, PTEN, p53 affect the level of aggressiveness of tumor cells. A comprehensive study of genetic markers in clinical practice allows for early diagnosis of neoplasms, differential diagnosis of tumors, as well as increasing the efficiency of diagnosis and treatment of ovarian neoplasms.</p></abstract><trans-abstract xml:lang="ru"><p>Новообразования яичников находятся на лидирующих позициях в структуре онкологических заболеваний репродуктивной системы женщин. Злокачественные опухоли яичников, как правило, обнаруживаются только на поздних стадиях заболевания, поэтому рак яичников является главной причиной неблагоприятных и смертельных исходов в онкологической гинекологии. Чтобы отличить формы опухолей друг от друга, оценить возможность трансформации пограничной опухоли в злокачественную, а также определить стадию развития опухолевого процесса, клинических критериев и инструментальных исследований бывает недостаточно, поэтому в диагностических целях используются и исследуются генетические маркеры трансформации пограничных опухолей яичников в высокодифференцированный рак яичников. В данной работе приводятся сведения по генетическим маркерам трансформации пограничных опухолей яичников в высокодифференцированный рак яичников. Исходя из анализа данных литературы, выявили, что мутационные изменения в таких генах, как BRAF, KRAS, PTEN, p53, влияют на уровень агрессивности клеток опухоли. Комплексное исследование генетических маркеров в клинической практике позволяет проводить раннюю диагностику новообразования, дифференциальную диагностику опухолей, а также повысить эффективность диагностики и лечения новообразований яичников.</p></trans-abstract><kwd-group xml:lang="en"><kwd>genetics</kwd><kwd>histology</kwd><kwd>ovarian tumor</kwd><kwd>borderline ovarian tumor</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>генетика</kwd><kwd>гистология</kwd><kwd>опухоль яичника</kwd><kwd>пограничная опухоль яичника</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Новикова Е.Г., Баталова Г.Ю.
