Проведение циторедуктивных операций у пациенток с распространенным раком яичников нередко подразумевает выполнение обширных комбинированных хирургических вмешательств, что может влиять на развитие послеоперационных осложнений.</p></sec><sec><title>Цель</title><p>Цель. Оценить непосредственные результаты хирургического лечения у пациенток с распространенным раком яичников.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включены 190 пациенток с IIB–IVB стадией рака яичника, проходивших лечение в условиях онкогинекологического отделения НМИЦ онкологии имени Н. Н. Петрова (Санкт-Петербург) с августа 2017 по сентябрь 2020 года. Оценка степени диссеминации по брюшине проводилась при помощи подсчета индекса перитонеального карциноматоза (PCI). Степень сложности хирургического вмешательства оценивалась при помощи классификации Aletti. Анализ тяжести послеоперационных осложнений проводился в соответствии с классификацией Clavien – Dindo.</p></sec><sec><title>Результаты</title><p>Результаты. Частота развития послеоперационных осложнений зависела от индекса хирургической сложности операции (5 % – при низком индексе хирургической сложности, 15 % – при среднем, 63 % – при высоком; р &lt; 0,0010). В группе первичных циторедуктивных операций преобладали вмешательства средней (48,90 %) и высокой сложности (24,44 %), в группе интервальных циторедуктивных вмешательств преобладали операции низкого (52,40 %) и среднего (36,50 %) уровня сложности. Индекс хирургической сложности зависел от степени диссеминации опухолевого процесса (PCI). Длительность операции, объем кровопотери, длительность госпитализации, необходимость выполнения резекции кишки зависели от индекса перитонеального карциноматоза и сложности хирургического вмешательства (р &lt; 0,0001).</p></sec><sec><title>Выводы</title><p>Выводы. Уровень сложности хирургического вмешательства у пациенток с распространенным раком яичника зависит от степени перитонеального распространения. Выполнение первичных оптимальных циторедуктивных операций сопряжено с более высокой сложностью хирургического вмешательства, что повышает частоту развития послеоперационных осложнений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Cytoreductive surgery in patients with advanced ovarian cancer often involves extensive combined surgical interventions, which can affect the development of postoperative complications.</p></sec><sec><title>Aim</title><p>Aim. To evaluate the results of surgical treatment in patients with advanced ovarian cancer.</p></sec><sec><title>Methods</title><p>Methods. The study included 190 primary IIB–IV stage ovarian cancer patients who underwent surgical treatment in the oncogynecological department of the National Medical Research Centre of Oncology n. a. N. N. Petrov (Saint Petersburg, Russia) from August 2017 to August 2020. The dissemination in the peritoneum was assessed by calculating the peritoneal carcinomatosis index (PCI). Surgical complexity score was assessed using Aletti’s classification. Analysis of postoperative complications was carried out in accordance with the Clavien – Dindo classification.</p></sec><sec><title>Results</title><p>Results. The incidence of postoperative complications depended on the index of surgical complexity score (5 % – with a low index, 15 % – with median, 63 % – with a high one, p &lt; 0.0010). In the group of primary cytoreductive surgeries, cases of median (48.9 %) and high complexity score (24.44 %) prevailed; in the group of interval debulking surgery, cases of low (52.4 %) and median (36.5 %) complexity score prevailed. The index of surgical complexity score depended on the peritoneal carcinomatosis index (PCI). The operation time, the volume of blood loss, the duration of hospitalization, frequency of bowel resection depended on the peritoneal carcinomatosis index and the surgical complexity score (p &lt; 0.0001).</p></sec><sec><title>Conclusions</title><p>Conclusions. The level of surgical complexity score in patients with advanced ovarian cancer depends on the peritoneal carcinomatosis index. The level of surgical complexity score is higher in the group of primary debulking surgery, which effect on frequency of postoperative complications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рак яичников</kwd><kwd>индекс перитонеального карциноматоза</kwd><kwd>циторедуктивные операции</kwd><kwd>послеоперационные осложнения</kwd><kwd>сложность хирургического вмешательства</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ovarian cancer</kwd><kwd>peritoneal carcinosis index</kwd><kwd>debulking surgery</kwd><kwd>postoperative complications</kwd><kwd>surgical complexity score</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">Kotsopoulos J, Rosen B, Fan I, Moody J, McLaughlin JR, Risch H, May T, Sun P, Narod SA.
