Is autologous transplant in relapsed DLBCL patients achieving only a PET+ PR appropriate in the CAR T-cell era?

ABSTRACT: For relapsed chemosensitive diffuse large B-cell lymphoma (DLBCL), consolidation with autologous hematopoietic cell transplantation (auto-HCT) is a standard option. With the approval of anti-CD19 chimeric antigen receptor T cells in 2017, the Center for International Blood and Marrow Transplant Research (CIBMTR) reported a 45% decrease in the number of auto-HCTs for DLBCL in the United States. Using the CIBMTR database, we identified 249 relapsed DLBCL patients undergoing auto-HCT from 2003 to 2013 with a positive positron emission tomography/computed tomography (PET/CT)+ partial response prior to transplant were identified. The study cohort was divided into 2 groups: early chemoimmunotherapy failure (ECF), defined as patients with primary refractory disease (PRefD) or relapse within 12 mo
