On multistep tumor growth models of fractional variable-order.

On multistep tumor growth models of fractional variable-order. Biosystems. 2020 Nov 25;:104294 Authors: Valentim CA, Rabi JA, David SA, Tenreiro Machado JA Abstract Fractional mathematical oncology is a research topic that applies non-integer order calculus to tackle cancer problems such as tumor growth analysis or its optimal treatment. This work proposes a multistep exponential model with a fractional variable-order representing the evolution history of a tumor. Model parameters are tuned according to variable fractional order profiles while assessing their capability of fitting a clinical time series. The results point to the superiority of the proposed model in describing the experimental data, thus providing new perspectives for modeling tumor growth.
