Определить предиктивную значимость уровня опухолевого маркера СА‑125 перед началом терапии. Проанализировать частоту нежелательных явлений, потребовавших редукции дозы или отмены препарата.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы: Проведен ретроспективный анализ данных 110 пациенток с серозным раком яичников высокой степени злокачественности I–IV стадий с мутацией в генах BRCA1 / 2, получавших поддерживающую терапию олапарибом в СПб ГБУЗ «Городской клинический онкологический диспансер» в период с 2020 по 2024 гг. Пациентки были стратифицированы на три группы: назначение олапариба в первой линии (1L, n = 64), после первого рецидива (ПР1, n = 24) и после двух и более рецидивов (ПР2+, n = 22). Статистический анализ включал оценку выживаемости по методу Каплана — Мейера и многофакторный анализ с использованием регрессии Кокса.</p></sec><sec><title>Результаты</title><p>Результаты: Медиана ВБП в группе 1L не была достигнута. В группах ПР1 и ПР2+ медиана ВБП составила 49 и 20 месяцев соответственно (p &lt; 0,001). Исходно повышенный уровень СА‑125 (&gt; 35 Ед / мл) перед началом терапии олапарибом был ассоциирован со статистически значимым увеличением риска прогрессирования в 3,2 раза (отношение рисков [ОР] 3,2; 95 % ДИ 1,5–6,8; p = 0,003). Токсичность, потребовавшая коррекции дозы, зарегистрирована у 14,1 %, 12,5 % и 13,6 % пациенток в группах 1L, ПР1 и ПР2+ соответственно.</p></sec><sec><title>Выводы</title><p>Выводы: Поддерживающая терапия олапарибом продемонстрировала высокую клиническую эффективность и управляемый профиль безопасности в условиях реальной практики. Наибольшая польза от терапии наблюдается при ее назначении в первой линии. Повышенный уровень СА‑125 (&gt; 35 Ед / мл) перед началом лечения является неблагоприятным прогностическим маркером.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim: To evaluate the efficacy of olaparib maintenance therapy in real-world clinical practice in patients with BRCA-mutated ovarian cancer.</p></sec><sec><title>Objectives</title><p>Objectives: To evaluate progression-free survival (PFS) by olaparib therapy line. To determine the predictive value of the level of the cancer marker CA-125 before therapy. To analyze the incidence of adverse events requiring dose reduction or drug discontinuation.</p></sec><sec><title>Materials and Methods</title><p>Materials and Methods: A retrospective analysis included data of 110 patients with Stage I–IV BRCA1 / 2 mutated high-grade serous ovarian cancer, who received olaparib maintenance therapy at the St. Petersburg Municipal Clinical Oncology Dispensary from 2020 to 2024. Patients were stratified into three groups: first-line olaparib (1L, n = 64), olaparib after the first recurrence (AR1, n = 24), and olaparib after two or more recurrences (AR2+ , n = 22). Statistical analysis included Kaplan-Meier survival estimates and multivariate analysis using Cox regression.</p></sec><sec><title>Results</title><p>Results: The median PFS was not reached in the 1L group. In the AR1 and AR2+ groups, the median PFS was 49 and 20 months, respectively (p &lt; 0.001). An elevated baseline CA-125 level (&gt; 35 U / mL) before initiation of olaparib therapy was associated with a statistically significant 3.2-fold increase in the risk of progression (odds ratio [OR] 3.2; 95 % CI 1.5–6.8; p = 0.003). Toxicities requiring dose adjustment were reported in 14.1 %, 12.5 %, and 13.6 % of patients in the 1L, AR1, and AR2+ groups, respectively.</p></sec><sec><title>Conclusions</title><p>Conclusions: Olaparib maintenance therapy demonstrated high clinical efficacy and a manageable safety profile in real-world settings, with the greatest benefit observed in the first-line setting. Elevated pre-treatment CA-125 levels (&gt; 35 U / mL) are an unfavorable prognostic marker.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичников</kwd><kwd>олапариб</kwd><kwd>поддерживающая терапия</kwd><kwd>BRCA</kwd><kwd>СА‑125</kwd><kwd>выживаемость без прогрессирования</kwd><kwd>токсичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>olaparib</kwd><kwd>maintenance therapy</kwd><kwd>BRCA</kwd><kwd>CA-125</kwd><kwd>progression-free survival</kwd><kwd>toxicity</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">Webb P.M., Jordan S.J.
