Simulation analysis for tumor radiotherapy based on three‐component mathematical models

Abstract

Objective To setup a three‐component tumor growth mathematical model and discuss its basic application in tumor fractional radiotherapy with computer simulation. Method First, our three‐component tumor growth model extended from the classical Gompertz tumor model was formulated and applied to a fractional radiotherapy with a series of proper parameters. With the computer simulation of our model, the impact of some parameters such as fractional dose, amount of quiescent tumor cells, and α/β value to the effect of radiotherapy was also analyzed, respectively. Results With several optimal technologies, the model could run stably and output a series of convergent results. The simulation results showed that the fractional radiotherapy dose could impact the effect of radiotherapy significantly, while the amount of quiescent tumor cells and α/β value did that to a certain extent. Conclusions Supported with some proper parameters, our model can simulate and analyze the tumor radiotherapy program as well as give some theoretical instruction to radiotherapy personalized optimization.

Re: Simulation analysis for tumor radiotherapy based on three‐component mathematical models

“…We were excited to read the recent article by Hong & Zhang "Simulation analysis for tumor radiotherapy based on three-component mathematical models". 1 This is a topic that deserves much attention, as mathematical predictions of treatment response may ultimately help personalize radiation dose and dose fractionation. 2,3 Hong & Zhang conclude from simulation results of their model four findings:…”

Lung Cancer Radiotherapy: Simulation and Analysis Based on a Multicomponent Mathematical Model

“…As the superiority of simplicity and stability, the ODE model has been widely used in the fields of infection control, pharmacodynamics, and tumor metabolism [18][19][20][21]. In our past work, we have developed a mathematical model based on ODE for tumor radiotherapy [22]. So, the model in this paper is elicited in ODE format.…”

Exposure-response modeling improves selection of radiation and radiosensitizer combinations

“…Numerous quantitative models have been developed to describe the effects of radiotherapy on tumors, with or without chemical intervention [11][12][13][14]. These models range from the simple, yet ubiquitous, linear-quadratic model of radiobiology [15], to complex systems pharmacology models that include particular pathways and processes (such as the cell cycle) that are relevant to the given treatment [16,17].…”
