Tumor microenvironmental influences on tumor growth using non-extensive entropy

We have used non-extensive entropy to study the influence of the non-immunogenic tumor microenvironmental effects on dynamics of tumor growth. For this purpose, we have first employed the Tsallis and Abe entropies with different parameters. Then, we have applied the phenomenological model equation to determine the steady-state distribution for investigating tumor growth. Numerical results show that the steady-state distribution can change with some factors. We also plot this quantity versus the tumor population for studying the properties of steady state of tumor growth. (author)
