The Cytotoxic Effect of Rtks Inhibitors on Glioblastoma Cells. A Mathematical Model for Treatment Protocols Optimization

Medical oncology has seen an exponential growth in the last 20 years with the vast majority of malignancies receiving new therapeutic options with substantial benefits to patients� survival and quality of life. Glioblastomas (GBMs), however, have remained largely incurable, with over 90% of patients dying within 5 years of diagnosis. The estimation of a dose�effect type ratio, regarding the action of an oncological drug on tumor cells, leads to relevant conclusions in establishing the optimal medication, specific to the chemotherapeutic act. The identification of the optimal dose of agent is very important, based on experiments on cell lines with regards to cellular kinetics. In this study, we developed a mathematical model based on the specific transfer function of a dose�response action type of a drug on tumor cells in vitro.
