To describe the immediate and long-term results of a series of cases of the use of epoetin alfa in preoperative therapy of malignant tumors of the female reproductive system, performed at a single clinical center.</p><p><bold>Materials and methods</bold>. The article presents the experience of treating anemia (2–3 degrees of severity) of various origins with erythropoiesis-stimulating drugs in monotherapy or in combination with iron preparations in 5 patients who sought medical care at the Federal Research and Clinical Center for Specialized Medical Care and Medical Technologies, Federal Biomedical Agency of the Russian Federation for the period from August 2024 to February 2025 due to malignant tumors of the female reproductive system of various localizations, for whom surgical treatment was indicated.</p><p><bold>Results</bold>. The mean age of patients at the time of surgery was 55.4 ± 32.5 years. The mean body mass index of patients was 25.6 ± 1.6. The mean hemoglobin level in the blood at the time of diagnosis was 78.2 ± 3 g / L. The mean duration of preoperative drug therapy was 4.4 ± 1.5 weeks, during which 2 (40 %) patients received monotherapy with epoetin alfa (40,000 IU once a week subcutaneously), 3 (60 %) patients with serum ferritin &lt;100 ng / ml and serum transferrin iron saturation &lt;20 % – combination therapy in combination with iron [III] hydroxide sucrose complex (intravenous jet stream 200 mg 3 times a week). The mean hemoglobin level at the time of surgery was 102.2 ± 8.5 g / L. The average postoperative hospital stay was 7.2 ± 5.5 days. No intra- or perioperative complications were observed. The average postoperative follow-up period was 7 (3–9) months, during which no recurrence of the disease was detected (0 %).</p><p><bold>Conclusion</bold>. The correction of multifactorial anemia of 2–3 degrees of severity in the preoperative period in malignant tumors of the female reproductive system using erythropoietins in monotherapy or in combination with iron preparations within a reasonable time ensures the achievement of the target hemoglobin level for subsequent surgical treatment, an acceptable quality of life for patients, and also allows to reduce the risk of perioperative complications and avoid unnecessary blood transfusions.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – описать непосредственные и отдаленные результаты серии клинических случаев применения эпоэтинаальфа в предоперационной терапии злокачественных опухолей женской репродуктивной системы, выполненной на базе одного клинического центра.</p><p><bold> Материалы и методы.</bold> Представлен опыт терапии анемии (II–III степени тяжести) различного генеза эритропо эзстимулирующими препаратами в монотерапии или в комбинации с препаратами железа у 5 пациенток, обратившихся за медицинской помощью в Федеральный научно-клинический центр специализированных видов медицинской помощи и медицинских технологий Федерального медико-биологического агентства России за период с августа 2024 г. по февраль 2025 г. по поводу злокачественных опухолей женской репродуктивной системы раз личных локализаций, которым было показано хирургическое лечение. Результаты. средний возраст пациенток на момент операции составлял 55,4 ± 32,5 года, средний индекс массы тела – 25,6 ± 1,6 кг / м2, средний уровень гемоглобина крови на момент установления диагноза – 78,2 ± 3 г / л. среднее время предоперационной лекарственной терапии составило 4,4 ± 1,5 нед, в течение которого 2 (40 %) пациентки получали монотерапию эпоэтином альфа (40 000 Ме 1 раз в неделю подкожно), 3 (60 %) пациентки с показателями уровня сывороточного ферритина &lt;100 нг / мл и насыщения железом сывороточного трансферрина &lt;20 % – комбинированную терапию в сочетании с железа [III] гидроксид сахарозным комплексом (внутривенно струйно 200 мг 3 раза в неделю). средний уровень гемоглобина на момент проведения операции составил 102,2 ± 8,5 г / л, среднее число послеоперационных койко-дней – 7,2 ± 5,5. Интра- и периоперационных осложнений не отмечалось. средний период послеоперационного наблюдения составил 7 (3–9) мес, в течение которого не было выявлено рецидивов заболевания (0 %).</p><p><bold>Выводы</bold>. Коррекция многофакторной анемии II–III степени тяжести в предоперационном периоде при злокачественных опухолях женской репродуктивной системы с помощью эритропоэтинов в монотерапии или в комбинации с препаратами железа в разумные сроки обеспечивает достижение целевого уровня гемоглобина для проведения последующего хирургического лечения и приемлемое качество жизни пациенток, а также позволяет снизить риск развития периоперационных осложнений и избежать проведения необоснованных гемотрансфузий.</p></trans-abstract><kwd-group xml:lang="en"><kwd>epoetin alfa</kwd><kwd>anemia</kwd><kwd>tumor of the female reproductive system</kwd><kwd>preoperative therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>эпоэтин альфа</kwd><kwd>анемия</kwd><kwd>опухоль женской репродуктивной системы</kwd><kwd>предоперационная терапия</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was conducted with the financial support of JSC “Sotex” (Russia).
