Противоопухолевая терапия с использованием химиотерапевтических препаратов различных классов в детском возрасте оказывает негативное влияние на «препубертатные» и «пубертатные» гонады. Санкт-петербургская группа по сохранению фертильности у детей с онкологическими заболеваниями НМИЦ онкологии им. Н.Н. Петрова (руководитель группы – А.П. Карицкий) разработала программу «Снежинка», первичной целью которой является сохранение фертильности у онкологических пациентов до 17 лет, конечной – создание криобанка биологического материала.</p><p>Цель работы – представить первые результаты таргетного набора пациентов в программу «Снежинка», а также проанализировать скорость этого набора.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В ФГБУ «НМИЦ онкологии им. Н.Н. Петрова» Минздрава России инициированы протоколы клинического исследования по сохранению фертильности у девочек и мальчиков препубертатного и пубертатного возраста. Запланированное число участников исследования – 125 человек. Прогноз набора – 5 пациентов в месяц, или 60 пациентов в год.</p></sec><sec><title>Результаты</title><p>Результаты. За время работы программы на предмет риска развития гонадотоксичности после противоопухолевого лечения были скринированы 28 первичных пациентов в возрасте от 1 года до 17 лет. Четырнадцать пациентов не соответствовали критериям включения в программу, в финальный отчет были включены 14 детей. Причинами исключения стали низкий риск гонадотоксичности (n = 9), отказ от инвазивного вмешательства (n = 5), для семьи одного мальчика генетическое отцовство не являлось приоритетным. В 6 случаях диагностированы герминогенноклеточные опухоли гонад, 3 пациента были с саркомами мягких тканей и 2 – с лимфомами, по 1 – с остеосаркомой, опухолью Вильмса и медуллобластомой. Криоконсервация ткани яичника выполнена 6 девочкам, ткани яичка – 4 мальчикам и еще 4 подросткам – извлечение спермы с помощью мастурбации. Задержки начала противоопухолевого лечения не было ни в одном случае.</p></sec><sec><title>Выводы</title><p>Выводы. Необходимы дальнейшие исследования гонадотоксичности, поскольку в ближайшие годы число выживших пациентов, перенесших рак в детском возрасте, будет расти.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Antitumor therapy using various different classes chemotherapy drugs in childhood has a negative impact on prepubertal and pubertal gonads. One of the groups dealing with the problems of pediatric oncofertility was the St. Petersburg Group for the Preservation of Oncofertility in Children with Cancer. The primary goal of the “Snowflake” program (N.N. Petrov National Medical Research Center of Oncology, leader A.P. Karitsky) is to preserve fertility in patients under 17 years old with tumors, the end point is the creation of a cryobank of biological material.</p><p>The purpose of the work is to present the first results of targeted recruitment of patients to the “Snowflake” program, as well as to analyze the speed of this recruitment.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The N.N. Petrov National Medical Research Center of Oncology initiated clinical study protocols for preserving fertility in prepubescent and puberty girls and boys. The planned number of study participants is 125 people. The recruitment forecast is 5 patients per month, or 60 patients per year.</p></sec><sec><title>Results</title><p>Results. During the program, 28 primary children aged one to 17 years were screened for the risk of developing gonadotoxicity after anticancer treatment. Fourteen patients did not meet the inclusion criterias, 14 children were included in the final report. The reasons for exclusion were low risk of gonadotoxicity (n = 9), refusal of invasive intervention (n = 5), genetic paternity was not a priority for the family of one boy. In 6 cases, germ cell tumors were diagnosed, 3 cases were patients with soft tissue sarcomas and 2 were patients with lymphomas, one each with osteosarcoma, Wilms tumor and medulloblastoma. Cryopreservation of ovarian tissue was performed for 6 girls, testicular tissue for 4 boys, 4 more teenagers performed sperm extraction using masturbation. There was no delay in initiating anticancer treatment in either case.</p></sec><sec><title>Conclusions</title><p>Conclusions. Further studies of gonadotoxicity are needed as the number of survivors with childhood cancer will increase in the coming years.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>подростки</kwd><kwd>злокачественные опухоли</kwd><kwd>сохранение фертильности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>adolescents</kwd><kwd>malignant tumors</kwd><kwd>fertility preservation</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">Колыгин Б.А., Кулева С.А.
