摘要:
 【摘 要】 目的:通过借鉴经典Gompertz肿瘤生长数学模型,构建肿瘤放疗的分次放疗模型,探讨基于模型的肿瘤放疗个体化优化。 方法:分析经典Gompertz肿瘤生长模型,选择合适的参数,构建分次放疗模型,并利用计算机模拟,从基本模型、单次放疗、分次放疗等方面进行分析,讨论单次剂量、分次剂量以及α/β值对放疗效果的影响。 结果:整体模型均能稳定运行并收敛到稳定的结果。模拟结果显示放疗剂量和α/β值均对放疗效果影响明显,需要大量精确的数据支持以实现放疗的个体化优化。 结论:基于Gompertz肿瘤生长数学模型的放疗模型能在一定程度上模拟放射治疗的疗效,为指导放疗个体化优化提供理论上的指导。
Abstract:
 Abstract: Objective To discuss the optimization of personalized radiotherapy based on the fractional radiotherapy mathematical model derived from classical Gompertz mathematical model of tumor growth. Methods The classical Gompertz model of tumor growth was analyzed, and the proper parameters were selected to establish a fractional radiotherapy model. With the computer simulation, we discussed the effects of single dose, fractional dose and α/β value on the therapeutic effect. Results The whole model run stably and output stable results. The simulation results revealed that both the radiotherapy dose and α/β value had remarkable effects on the therapeutic effect of radiotherapy, which indicated that lots of accurate data were necessary for the optimization of personalized radiotherapy. Conclusion To some extent, the Gompertz model-based radiotherapy model can simulate the therapeutic effect of radiotherapy as well as provide some theoretical instructions for the optimization of personalized radiotherapy.
