Set-up of different simulations an their biological outcomes. Each row indicates the numerical values used for the chemotherapeutic parameters αA (cytotoxicity), σ (diffusion coefficient), μ (infusion rate), and the position of ω ⊂ Ω ⊂ ℝ2. Simulation 1 was performed in a two-dimensional domain Ω = [0, 1] × [0, 1], while simulations 2–5 were performed in a one-dimensional domain Ω = [0, 1].
