Abstract

Brain tumors are among the deadliest types of cancer and the most challenging to treat. Predicting the growth behavior of tumors can help physicians choose the best treatment program. Herein, a numerical technique based on the meshless radial point interpolation methods is presented for simulating the growth of brain tumors under the effects of radiotherapy and chemotherapy. In this work, the stress field induced in the brain due to tumor growth and its effect on tumor diffusion is analyzed. In the meshfree method, to obtain the system of discrete equations, the weak-form of the coupled nonlinear system of governing equations is developed. Part of the simulations is based on clinical data obtained from other research; additionally, data found in the literature is used to validate the results. The effects of various conventional treatment programs, with and without considering the effect of the stress field in brain tissue, are analyzed and compared. Furthermore, the order of radiotherapy and chemotherapy treatments is investigated. It is shown that when the stress effect is considered, the points with maximum stress are where tumor growth is highest. After the cell density reaches its maximum value at these points, growth is transferred to the surrounding areas.
