Session Title: Mathematical Modeling in Cancer Therapy
Question 1: Which of the following parameters have been derived from clinical outcome data?
Reference:Grassberger, C., and H. Paganetti. "Methodologies in the modeling of combined chemo-radiation treatments." Physics in Medicine & Biology 61.21 (2016): R344.
Choice A:Optimal drug dosing schedules
Choice B:General radio-sensitization factor (x*D)
Choice C:Differential cell cycle drug- and radiation sensitivity
Choice D:Radiation equivalent cell kill by drug
Choice E:B and E.
Question 2: Which of the following constitute the main challenges when modeling molecularly targeted agents compared to traditional chemotherapy based on clinical data?
Reference:Zhao, Boyang, Michael T. Hemann, and Douglas A. Lauffenburger. "Modeling tumor clonal evolution for drug combinations design." Trends in cancer 2.3 (2016): 144-158.
Choice A:Longer time scales in administration of targeted agents
Choice B:Mechanisms of action and their differences not well understood
Choice C:Genetically distinct subpopulations with great differential in terms of sensitivity (sensitive – resistant)
Choice D:Patient response more unpredictable with targeted agents
Choice E:A and C.
Question 3: Physical processes in cancer are important, including:
Reference:Mechanistic patient-specific predictive correlation of tumor drug response with microenvironment and perfusion measurements. J Pascal, EL Bearer, Z Wang, EJ Koay, SA Curley, V Cristini, Proceedings of the National Academy of Sciences 110 (35), 14266-14271
Choice A:Perfusion of drug molecules and cell substrates
Choice B:Cell-cell and cell-stroma mechanical interactions
Choice C:Drug and nanocarrier specific and nonspecific interactions with endothelium
Choice D:All of the above
Question 4: Physical processes do not appear in vitro because of:
Reference:Integrated nanotechnology platform for tumor-targeted multimodal imaging and therapeutic cargo release. H Hosoya, AS Dobroff, WHP Driessen, V Cristini, LM Brinker, FI Staquicini, ... Proceedings of the National Academy of Sciences 113 (7), 1877-1882
Choice A:Absence of transport gradients of drug and cell substrates
Choice B:Cells do not interact
Choice C:Cells do not uptake
Choice D:Cells do not move
Question 5: Biomechanical model-based deformable image registration (DIR) has the potential to be more accurate than intensity-based DIR when the images present no or few other features than the boundaries of the structure to register:
Reference:Velec, Michael et al. “Utility and validation of biomechanical deformable image registration in low-contrast images” Practical Radiation Oncology, Volume 5 , Issue 4 , e401 - e408
Choice A:True
Choice B:False
Question 6: Considering organs with uniform or spatially heterogenous elastic properties for biomechanical model-based image registration has always been found to have low impact on registration accuracy:
Reference:Savamati, Navid et al. “Effect of material property heterogeneity on biomechanical modeling of prostate under deformation.” Physics in Medicine & Biology, Volume 60, Number 1
Choice A:True
Choice B:False
