^*Difference in volumes defined on first and last posttracer scans (6 d).

^†Difference in volumes defined on first and last posttherapy scans (~6 d).

^‡Difference in product of largest perpendicular diameters at 2 mo compared with the first posttracer imaging time point.

Results for individual tumors are given in the supplemental material.
