↵a Two different tumor-response criteria were applied to the volume data (25/50 uses the same criteria as used for CP-response determinations, 40/65 denotes PR as >65% decrease from baseline and PD as >40% increase from the prior lowest tumor size). Unless otherwise noted, values represent the number of MR imaging time points.
