Using control theory to make cancer chemotherapy beneficial from phase dependence and resistant to drug resistance

Marek Kimmel (Rice University, USA) | Andrzej Świerniak (Silesian University of Technology, Poland) |
Two major obstacles against successful chemotherapy of cancer are the cell-cycle-phase dependence of treatment, and the emergence of resistance of cancer cells to cytotoxic agents. One way to understand and overcome these two problems is to apply optimal control theory to mathematical models of cell cycle dynamics. These models should include division of the cell cycle into subphases and/or the mechanisms of drug resistance. We review our relevant results in mathematical modelling and control of the cell cycle and of the mechanisms of gene amplification (related to drug resistance), and estimation of parameters of the constructed models.
