Проведен анализ данных у детей с морфологически подтвержденными диагнозами нефробластомы (n = 31), забрюшинной нейробластомы и нейробластомы надпочечника (n = 58), гепатобластомы (n = 20). Построены нелинейные модели с использованием функции Гомпертца и экспоненциальной функции, описывающие рост опухоли. Сравнительный анализ показал, что данные более точно аппроксимируются S-образной зависимостью. По результатам статистических расчетов и математического моделирования синхронизированы возраст пациентов и сроки реализации метастатического потенциала для нейробластомы и гепатобластомы. Полученные данные могут использоваться при разработке скрининговых программ в детской онкологии.</p></abstract><trans-abstract xml:lang="en"><p>Volumetric and kinetic characteristics of embryonic tumors were studied following an initial ultrasound diagnosis of malignant neoplasms (MN) of 109 children of both sexes at the age of 1-366 days. Analysis was made of the data for children with morphologically confirmed diagnosis of the nephroblastoma (n = 31), retroperitoneal neuroblastoma, neuroblastoma adrenal (n = 58), and hepatoblastoma (n = 20). Nonlinear models were built using the Gompertz function and the exponential functions describing the tumor growth. The comparative analysis showed that the data are more exactly approximated by of the S-shaped relationship. According to the results of statistical calculations and mathematical modeling, the patient age and the time of realizing the tumor metastatic potential were synchronized. The estimated age period suggests the possibility of early visualization of MN in the first four months of life in much smaller quantities that are actually diagnosed.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Braun J., Garsia K. // GDMS. 2004.
