A Prey-Predator Model for Immune Response and Drug Resistance in Tumor Growth
In this paper the interaction between cancer and immunological system is analysed. The model is a modification of a one proposed by de Vladar and Gonzales. For our model the stability is analysed. Furthermore, the effect of a therapy schedule with fixed concentration is investigated. Mathematically, the effect of therapy is viewed as a moderating term both for tumor cell growth rate and for T-cells death rate. In conclusion, a systematic computational analysis is associated to the obtained theoretical results.
