Day 30 SUVmax predicts progression in patients with lymphoma achieving PR/SD after CAR T-cell therapy.

About 70% of patients with large B-cell lymphoma (LBCL) who are treated with axicabtagene ciloleucel (axi-cel) and who achieve a partial response (PR) or stable disease (SD) on the day 30 (D30) positron emission tomography (PET)-computed tomography (CT) scan progress; however, the factors that are predictive of progression are unknown. This a retrospective study of patients with LBCL who were treated with axi-cel at MD Anderson Cancer Center between January of 2018 and February of 2021. Among 50 patients with D30 PR/SD, 13 (26%) converted to a complete response (CR).
