Classification based on quantitative standardized uptake value for total functional burden (SUVtotal) changes during first 12 weeks of therapy for (A) Progression-free survival (PFS) and (B) radiographic PFS. Patients classified as having progressive disease using quantitative thresholds of change in SUVtotal had poorer progression-free interval. Log-rank tests showed significant differences in progression-free intervals across response groups (P < .001 for both PFS and radiographic PFS).
