В исследование ретроспективно включено 57 больных РЯ low grade, прооперированных в отделении онкогинекологии НМИЦ онкологии имени Н. Н. Блохина с 2018 по 2023 г. Первичной конечной точкой исследования являлась безрецидивная и общая выживаемость больных. Вторичной конечной точкой являлась оценка факторов, влияющих на выживаемость пациенток.Результаты. У 17 (29,9 %) пациенток была диагностирована ранняя стадия болезни, а у 40 (70,1 %) – распространенный процесс. При распространенных стадиях частота поражения регионарных лимфатических узлов составила 27,5 %. Первичная циторедуктивная операция выполнена у 28 (70 %) больных, остальным 12 (30 %) проведена интервальная циторедукция. В зависимости от полноты циторедукции первичные операции распределились следующим образом: полные – 21 (75 %), оптимальные – 6 (21,4 %), неоптимальные 1 (3,6 %); интервальные: полные – 5 (41,7 %), оптимальные – 4 (33,3 %), неоптимальные – 2 (16,7 %), у 1 больной (8,3 %) – эксплоративная лапаротомия. Для первичной полной циторедукции средний индекс PCI составил 7,5 балла, для оптимальной – 11,5 балла, для полной и оптимальной интервальной операции – 8 и 13 баллов соответственно. В группе раннего РЯ 3-летняя общая выживаемость (ОВ) и безрецидивная выживаемость (БРВ) составили 100 % при медиане наблюдения в 30,4 (12–57) мес. В группе диссеминированного РЯ low grade 3-летняя ОВ при первичной циторедукции составила 100 %, в группе интервальной циторедукции – 66,7 % при медиане наблюдения в 35,5 (3–72) мес. Первичная циторедуктивная операция статистически значимо увеличивала ОВ. Общая частота рецидивов составила 40 %, при этом в группе первичных циторедуктивных операций частота рецидивов была равна 25 %, а в группе интервальных – 75 %. Среднее время до прогрессирования составило 11,6 (3–34) мес, медиана наблюдения – 35,5 (3–68) мес. В группе первичной циторедуктивной операции 3-летняя выживаемость без прогрессирования (ВБП) – 72,8 % и 17,5 % в группе интервальных операций.Выводы. Наши данные подтверждают, что для больных серозным РЯ low grade полная циторедуктивная операция коррелирует с улучшением показателей как ВБП, так и ОВ. Однако первичная циторедуктивная операция по сравнению с интервальной имеет достоверно лучшие отдаленные онкологические результаты. Рассматриваемая категория пациенток должна получать хирургическое лечение в онкологическом центре с высоким уровнем хирургической помощи и возможностью привлечения хирургов смежных специальностей.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to analyze treatment outcomes in patients with low-grade ovarian cancer (OC) of all stages and evaluate factors affecting overall survival (OS) and progression-free survival (PFS).Materials and methods. A retrospective analysis of 57 patients with low-grade OC was performed at the N. N. Blokhin National Medical Research Center of Oncology from 2018 to 2023. The primary endpoint was disease-free survival (DFS) and overall survival (OS). The secondary endpoint was assessment of survival-affecting factors. Statistical analysis included descriptive statistics and survival analysis.Results. Early-stage disease was diagnosed in 17 patients (29.9 %), advanced stage in 40 patients (70.1 %). In advanced stages, regional lymph node involvement was observed in 27.5 % of cases. Primary debulking surgery was performed in 28 patients (70 %), interval debulking surgery in 12 patients (30 %). Regarding the completeness of cytoreduction, primary complete resection was achieved in 21 (75 %) of cases, and optimal resection in 6 (21.4 %), suboptimal – 1 (3,6 %) case. In the interval debulking surgery, complete resection was achieved in 5 (41.7 %) of cases, and optimal removal in 4 (33.3 %), while 2 patients (16.7 %) underwent suboptimal surgery and 1 patient (8.3 %) underwent exploratory laparotomy. The PCI score for primary complete surgery was 7.5 points, for optimal surgery – 11.5 points. For complete interval surgery, the PCI was 8 points, for optimal interval surgery – 13 points. In the early-stage ovarian cancer (OC) group, 3-year OS and DFS were 100 % with a median follow-up of 30.4 months (12–57 months). In the advanced stage low-grade OC, 3-year OS was 100 % in patients who underwent primary cytoreductive surgery, while in the interval cytoreduction group it was 66.7 % with a median follow-up of 35.5 months (3–72 months). Primary debulking surgery significantly improved overall survival rates. The overall recurrence rate was 40 % (n=16), with a recurrence rate of 25 % (n=7) in the primary debulking surgery group and 75 % (n=9) in the interval debulking surgery group. The mean time to recurrence was 11.6 (3–34) months, with a median follow-up of 35.5 (3–68) months. The progression-free survival (PFS) was 72.8 % in the primary debulking surgery group and 17.5 % in the interval debulking surgery group.Conclusion. Our data confirm that in patients with low-grade serous OC, complete debulking surgery correlates with improved PFS and OS. However, primary debulking surgery compared to interval debulking surgery, demonstrates significantly better oncological outcomes. Patients with low grade OC should receive surgical treatment in an oncology center with a high level of surgical care and the possibility of involving surgeons from other specialties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичников</kwd><kwd>рак яичников low grade</kwd><kwd>циторедуктивная операция</kwd><kwd>хирургическое стадирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>low-grade ovarian cancer</kwd><kwd>cytoreductive surgery</kwd><kwd>debulking surgery</kwd><kwd>surgical staging procedure</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">Kurman R.
