На сегодняшний день в детской практике стратификация пациентов с герминогенными опухолями проводится при первичном обследовании на основании лишь распространенности процесса и характера предшествующей операции, при этом не учитывается скорость снижения опухолевых маркеров. Целью исследования стало создание номограммы для диагностики пролонгированного периода полуэлиминации (ПП) альфафетопротеина (АФП) у пациентов с герминогенными опухолями для выявления когорты больных с химиорезистентными процессами уже после индукционной полихимиотерапии и модификации их программы лечения с переходом на эскалированные и интенсифицированные режимы. Материалы и методы. С 1996 по 2017 г. в отделении химиотерапии и комбинированного лечения злокачественных опухолей у детей НМИЦ онкологии им. Н.Н. Петрова проводилось лечение 72 пациентов в возрасте до 18 лет с экстракраниальными герминогенными опухолями различной локализации, среди них с секретирующими формами были 46 (63,9 %) детей. В настоящем исследовании были произведены расчеты ПП АФП. Результаты. ПП АФП варьировал от 3 до 138 дней (среднее значение составило 15,6 дня). Критическое значение уровня ПП АФП, превышение которого было сопряжено со снижением показателей выживаемости, составило 6 дней. Проведенный унивариантный анализ показал значимое влияние пролонгации кинетических параметров АФП на общую выживаемость (ОВ) больных. ОВ при ПП £ 6 дней была равна 85,2 ± 7,9 %, при ПП &gt; 6 дней – 50,1 ± 12 % (р = 0,01873). Учитывая расчетные значения ПП, была создана функциональная шкала и построена номограмма для диагностики пролонгированного ПП АФП у пациентов с герминогенными опухолями. Информативность ее была следующей: чувствительность – 92,9 %, специфичность – 63,6 %, точность – 72,3 %. Ложноотрицательный результат был зафиксирован лишь в 1 (2,1 %) случае. Выводы. Вторичная стратификация пациентов должна проводиться после индукционного лечения с использованием принципов “response-based”-терапии. В таких случаях для диагностики снижения скорости распада АФП помогает номограмма, позволяющая выявить когорту больных с пролонгацией ПП опухолевого маркера, требующую ранней эскалации и интенсификации лечебных программ.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. Stratification of patients with germ cell tumors is primary carried out depends on stage and previous operation, at the same time is not considered the tumor markers decline. The aim of the study was the nomogram creation for diagnostics of the prolonged alfa-fetoprotein (AFP) half-life (HL) in patients with germ cell tumors in order to identify of a patients cohort with chemoresistant malignancy and to find treatment modification with transition to the escalated and intensified modality therapy. Materials and methods. Seventy-two patients less than 18 years old with extracranial germ cell tumors were treated in N.N. Petron National Medical Research Centre of Oncology between 1996 and 2017, among them with increased AFP were 46 (63.9 %) children. AFP half-life periods were calculated. Results. AFP half-life varied from 3 to 138 days (the average value was 15.6 days). A cut-off point at 6 days was found. An unfavourable decline in AFP was predictive overall survival (OS). OS rates were 85.2 ± 7.9 % and 50.1 ± 12 % in patients with HL £ 6 days, and with &gt; 6 days, respectively (p = 0.01873). Nomogram for diagnostics of the prolonged AFP HL in patients with childhood extracranial germ cell tumors was built. Sensitivity, specificity and diagnostic accuracy of nomogram were 92.9 %, 63.6 % and 72.3 %, respectively. False negative result was in one case (2.1 %). Conclusions. Secondary stratification of patients has to be carried out after induction treatment with use of the principles of “response-based” of therapy. The nomogram allowing revealing the cohort of patients with prolongation of the period of AFP HL demanding early escalation and an intensification of medical programs helps with such cases for diagnostics of reduction in the rate of disintegration of AFP.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>герминогенные опухоли</kwd><kwd>полихимиотерапия</kwd><kwd>первично-резистентное течение</kwd><kwd>альфа-фетопротеин</kwd><kwd>номограмма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>germ cell tumors</kwd><kwd>chemotherapy</kwd><kwd>primary-resistant form</kwd><kwd>alfa-fetoprotein</kwd><kwd>nomogram</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">Olson T.A., Murray M.J., Rodriguez-Calindo C., Nicholson J.C., Billmire D.F., Krailo M.D., Dang H.M., Amatruda J.F., Thornton C.M., Arul G.S., Stoneham S.J., Pashankar F., Stark D., Shaikh F., Gershenson D.M., Covens A., Hurteau J., Stenning S.P., Feldman D.R., Grimison P.S., Huddart R.A., Sweeney C., Powles T., Lopes L.F., dos Santos Agular S., Chinnaswamy G., Khaleel S., Abouelnaga S., Hale J.P., Frazier A.L.
