Currently there is no definite optimal treatment strategy for this neoplasm. This study is supported by the Independent Ethics Committee and approved by the Academic Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. This study included patients with a verified diagnosis of CPC at the age 0 to 18 years in the period from 01.01.2009 to 31.12.2019. A total of 32 patients were registered. The median age was 2.65 years; 93.5% of CPCs were localized in the lateral ventricles. Initial metastases were found in 21.8% of cases; 5-year event-free survival (EFS) in children with metastases was lower than in those who did not have metastases 29 ± 17% and 49 ± 12%. In our cohort, gross total resection (GTR) was performed in 65.6% of patients. The five-year EFS in patients with complete CPC removal was higher than in patients who underwent subtotal and partial resection (63 ± 13%, 12 ± 11%, and 0%, respectively). In addition, overall survival (OS) was slightly higher in those who underwent GTR compared with subtotal and partial resection (74 ± 12%, 67 ± 16%, and 0%, respectively). Of the 32 children with CPCs, 15 children received programm chemotherapy, 17 non-programm chemotherapy, 5-year EFS in patients who received programm and non-programm chemotherapy was 79 ± 11% and 0%, respectively (p = 0.0006), 5-year OS in patients who received programm and non-programm chemotherapy was 93 ± 7% and 36 ± 14% (p = 0.0054). </p></abstract><trans-abstract xml:lang="ru"><p>Хориоидкарцинома (ХК) представляeт собой редкую, агрессивную опухоль головного мозга у детей с низкими показателями выживаемости. В настоящее время не существует определенной оптимальной стратегии лечения этого новообразования. Данное исследование одобрено независимым этическим комитетом и утверждено решением ученого совета ФГБУ «НМИЦ ДГОИ им. Дмитрия Рогачева» Минздрава России. В исследование были включены больные с верифицированным диагнозом «хориоидкарцинома» в возрасте от 0 до 18 лет в период с 01.01.2009 по 31.12.2019. Всего было зарегистрировано 32 пациента. Медиана возраста составила 2,65 года, 93,5% ХК локализовались в боковых желудочках. Метастазы на момент постановки диагноза были обнаружены в 21,8% случаев, 5-летняя бессобытийная выживаемость (БСВ) у детей с метастазами была ниже, чем у пациентов без метастазов: 29 ± 17% и 49 ± 12% соответственно. В нашей когорте полное удаление опухоли было выполено 65,6% пациентов. Пятилетняя БСВ у пациентов с полным удалением ХК была выше по сравнению с детьми, которым было выполнено субтотальное и частичное удаление опухоли (63 ± 13%, 12 ± 11% и 0% соответственно). К тому же общая выживаемость (ОВ) была немного выше у тех, кому было выполнено полное удаление опухоли, по сравнению с субтотальным и частичным удалением (74 ± 12%, 67 ± 16% и 0% соответственно). Из 32 детей с ХК программную химиотерапию (ХТ) получили 15 детей, непрограммную ХТ – 17, 5-летняя БСВ у пациентов, получивших программную и непрограммную ХТ, составила 79 ± 11% и 0% соответственно (р = 0,0006), 5-летняя ОВ у пациентов, получивших программную и непрограммную ХТ, составила 93 ± 7% и 36 ± 14% соответственно (р = 0,0054). </p></trans-abstract><kwd-group xml:lang="en"><kwd>choroid plexus carcinoma</kwd><kwd>choroid plexus tumors</kwd><kwd>children</kwd><kwd>chemotherapy</kwd><kwd>surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хориоидкарцинома</kwd><kwd>опухоли сосудистого сплетения</kwd><kwd>дети</kwd><kwd>химиотерапия</kwd><kwd>хирургия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sun M.Z., Oh M.C., Ivan M.E., Kaur G., Safaee M., Kim J.M., et al.
