The group of patients with stage IIB–IIIB ovarian cancer consisted of 107 patients, average age 50.7±11.5 years. Of these, 43 (40.2%) were women with stage IIB, 46 (43.0%) patients with stage IIIA, 3 (2.8%) patients with stage IIIA2, 15 (14.0%) patients with stage IIIB. Overall survival and progression-free survival were assessed. Statistical methods included survival analysis using the Kaplan–Meier method with the construction of survival curves, medians and standard errors of survival time, and comparison of survival between groups of patients using the log-rank test.</p> <p><bold>RESULTS: </bold>In patients with low-grade serous carcinoma, the five-year progression-free survival rate was higher than in patients with high-grade serous carcinoma (71.1±13.5 and 39.5±7.7%, respectively; p &lt;0.01). Primary surgical treatment performed in gynecological hospitals reduced the median life expectancy and five-year survival rate by 150.0 months and 25.9% (p &lt;0.01; RR=3.4; 95% CI=1.2–9.4). Interval cytoreduction reduced the median time to progression and five-year progression-free survival in patients with stage IIB–IIIB ovarian cancer (53.0±35.2 months and 43.7±16.5%) compared with patients underwent primary surgery (70.0±37.5 months and 57.3±6.0%). The five-year survival rate was higher in patients receiving a combination of platinum and taxanes — 94.7±5.1% (p &lt;0.01; HR=0.2; 95% CI=0.05–0.5).</p> <p><bold>CONCLUSION: </bold>In patients with stage IIB–IIIB ovarian cancer, factors such as primary surgical treatment performed in specialized gynecological oncology hospitals and adjuvant chemotherapy with platinum drugs in combination with taxane agents statistically significantly increase survival.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность.</bold> Актуальность исследования обусловлена остро стоящей проблемой оценки эффективности терапии рака яичников IIB–IIIB стадий.</p> <p><bold>Цель.</bold> Изучение показателей выживаемости пациенток после хирургического лечения различных форм IIB–IIIB стадий рака яичника в зависимости от ряда клинико-морфологических факторов.</p> <p><bold>Материал и методы.</bold> Материалом исследования служили<bold><italic> </italic></bold>долголетние наблюдения за пациентками, получавшими лечение в период с 2004 по 2021 г. в ГБУЗ «Приморский краевой онкологический диспансер», источником — медицинская карта стационарного больного (форма 003/у). Группу больных раком яичников IIB–IIIB стадий составили 107 пациенток, средний возраст 50,7±11,5 года. Из них с IIB стадией были 43 (40,2%) женщины, с IIIA стадией — 46 (43,0%) больных, с IIIA2 стадией — 3 (2,8%) пациентки, с IIIB стадией — 15 (14,0%) женщин. Оценивалась общая выживаемость и выживаемость без прогрессирования. Статистические методы включали анализ выживаемости методом Каплана–Мейера с построением кривых выживаемости, медианы и стандартных ошибок времени дожития, сравнения дожития групп пациенток с помощью логрангового критерия.</p> <p><bold>Результаты.</bold> У больных серозной карциномой low-grade пятилетняя выживаемость без прогрессирования выше, чем у пациенток с серозной карциномой high-grade (71,1±13,5 и 39,5±7,7% соответственно; р &lt;0,01). Первичное хирургическое лечение, выполненное в стационарах гинекологического профиля, снижало медиану продолжительности жизни и пятилетнюю выживаемость на 150,0 мес и 25,9% (р &lt;0,01; ОР=3,4; 95% ДИ=1,2–9,4). Интервальная циторедукция снижает медиану времени до прогрессирования и пятилетнюю выживаемость без прогрессирования у больных раком яичников IIB–IIIB стадий (53,0±35,2 мес и 43,7±16,5%) по сравнению с больными, оперированными первично (70,0±37,5 мес и 57,3±6,0%). Выше пятилетняя выживаемость у пациенток, получавших комбинацию препаратов платины и таксанов, — 94,7±5,1% (р &lt;0,01; ОР=0,2; 95% ДИ=0,05–0,5).</p> <p><bold>Вывод.</bold> У пациенток с раком яичников IIB–IIIB стадий статистически значимо повышают выживаемость такие факторы, как первичное хирургическое лечение, выполненное в специализированных стационарах онкогинекологического профиля, проведение адъювантной химиотерапии препаратами платины в комбинации с таксановыми агентами.</p></trans-abstract><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>stages IIB–IIIB</kwd><kwd>surgery</kwd><kwd>overall survival</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак яичника</kwd><kwd>IIB–IIIB стадии</kwd><kwd>хирургическое лечение</kwd><kwd>общая выживаемость</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Программа здравоохранения ГБУЗ «Приморский краевой онкологический диспансер»</institution></institution-wrap><institution-wrap><institution xml:lang="en">Healthcare program of the State Budgetary Healthcare Institution “Primorsky Regional Oncology Dispensary”</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Stewart C, Ralyea C, Lockwood S.
