Анализ эффективности программ выявления индивидуумов, предрасположенных к колоректальному раку, на основе имитационного моделирования

Abstract

Работа посвящена оценке эффективности различных программ обследования индивидуумов, предрасположенных к развитию колоректального рака, с помощью математического моделирования. В качестве критерия эффективности программы обследования рассматриваются значения показателей потерянных лет потенциальной жизни и общего количества обследованных индивидуумов за фиксированный период времени. Построена стохастическая индивидуум–ориентированная модель, описывающая динамику численности популяции, появление и рост полипов у конкретных индивидуумов, проведение массового обследования и выявление индивидуумов с полипами. Разработаны вычислительный алгоритм и моделирующая программа на основе методов Монте–Карло. Приведены результаты вычислительных экспериментов с моделью, отражающих различные сценарии проведения обследований индивидуумов популяции. Представлены рекомендации по проведению массового обследования индивидуумов в зависимости от метода выявления полипов, частоты обследования и средней продолжительности жизни в популяции.

We apply mathematical modeling to assert the efficiency of different screening programs for individuals predisposed to colorectal cancer. The criteria of program efficiency are potential years of life lost and the number of examinations within a fixed period of time. A stochastic individual-based model was built describing the dynamics of population size, polyp occurence and growth within the particular individuals, mass examination implementation and polyp detection. The computational algorithm and the modeling program were developed. Computer simulation results reflecting different mass examination scenarios are presented. Recommendations are presented concerning the mass examination programm choice depending on the polyp detection method, the examination frequency and the average life length.
