肿瘤生长与营养的关系:规律性与稳定性

Tumor Growth with Nutrients: Regularity and Stability

Matt Jacobs, Inwon Kim, Jiajun Tong

摘要:

本文研究了一个含营养物的肿瘤生长模型。由于肿瘤细胞之间存在接触抑制,该模型给出了动态补丁解。我们表明,当营养物质不扩散和细胞不死,肿瘤密度表现出规则化的动态。特别是,我们提供的收缩估计,指数率的渐近收敛,和边界的肿瘤补丁的正则性。这些结果与营养扩散模型或肿瘤细胞死亡率模型形成鲜明对比。

英文摘要:

In this paper we study a tumor growth model with nutrients. The model presents dynamic patch solutions due to the contact inhibition among the tumor cells. We show that when the nutrients do not diffuse and the cells do not die, the tumor density exhibits regularizing dynamics. In particular, we provide contraction estimates, exponential rate of asymptotic convergence, and boundary regularity of the tumor patch. These results are in sharp contrast to the models either with nutrient diffusion or with death rate in tumor cells.
