Pretreatment PSI as a prognostic factor. a Coefficient of determination, R2, for pretreatment PSI and growth rate λ as prognostic factors for tumor volume change after RT (2Gy x 30; q.d. 9 am) dependent on percentage of uncertainty in growth rate λ. b Predicted tumor volume change as a function of pretreatment PSI, dependent on uncertainty in growth rate λ. c Error in estimated patient-specific pretreatment PSI using Eq. 2 due to 5 % noise in measured tumor volumes and uncertainty in growth rate λ for N=10,000 independent simulations
