This paper deals with the cancer invasion model {u(t) = Delta u - chi del center dot (u del v) - xi del center dot (u del w) + mu u(1 - u - w), x is an element of Omega, t >0, u(t) = Delta v - v + u, x is an element of Omega, t >0, w(t) = -vw + eta w(1 - w - u), x is an element of Omega, t >0 in a bounded smooth domain Omega subset of R-2 with zero-flux boundary conditions, where chi, xi, mu and eta are positive parameters. Compared to previous mathematical studies, the novelty here lies in: first, our treatment of the full parabolic chemotaxis-haptotaxis system; and second, allowing for positive values of eta, reflecting processes with self-remodeling of the extracellular matrix. Under appropriate regularity assumptions on the initial data (u(0), v(0), w(0)), by using adapted L-p-estimate techniques, we prove the global existence and uniqueness of classical solutions when mu is sufficiently large, i.e., in the high cell proliferation rate regime.
