^∗Because of unavailable PET, MTV could not be derived for 1 patient not in CR and was marked as 0 mL for 8 patients in CR.

^†Similarly, MTV could not be derived for 2 patients not in CR and marked as 0 mL for 10 patients in CR.

^‡ctDNA on day 0 was used as baseline in 1 patient without prelymphodepletion ctDNA.

^§ctDNA was not checked in 3 patients without disease progression.

^‖ctDNA was not checked in 11 patients without disease progression.
