A Continuum Mechanics Model of Enzyme-Based Tissue Degradation in Cancer Therapies

Abstract: We propose a mathematical model to describe enzyme-based tissue degradation in cancer therapies. The proposed model combines the poroelastic theory of mixtures with the transport of enzymes or drugs in the extracellular space. The effect of the matrix degrading enzymes on the tissue composition and its mechanical response are accounted for. Numerical simulations in 1D, 2D and axisymmetric (3D) configurations show how an injection of matrix degrading enzymes alters the porosity of a biological tissue. We eventu… Show more

“…However, these models are not designed for describing the proliferation gradient that is observed in tumor spheroids. More complex models are needed to account for such a gradient [11,26,29,36] as well as the drug penetration in 3D tumors [16].…”

“…The governing equations are set in the fixed reference domain -the tissue at the initial timedenoted by Ω 0 . For the sake of simplicity, we assume that our system undergoes very small perturbations (see [Deville et al, 2018] for more details).…”

“…Different macroscale aspects of tumor growth have been investigated by continuum methods. 1,[11][12][13][14][15] Mechanical interactions, cell-cell adhesion, cell-matrix interactions, and ECM stiffness are studied by the so called method which occur in macroscales. On the other hand, most models use discrete framework to treat tumor growth numerically.…”
