We conducted a single-center retrospective study of 69 patients treated with Tisagenlecleucel, to evaluate the prognostic impact of TP53 alterations (TP53Alt), including mutations and/or deletions...These findings identify TP53 alterations as a strong adverse prognostic factor in patients with r/r B-ALL treated with CAR-T therapy. Screening for TP53Alt may guide risk-adapted strategies, including early consolidation with hematopoietic stem cell transplantation or alternative therapies.

CD19-targeted CAR T cells, such as tisagenlecleucel, have demonstrated high rates of complete remission and long-lasting responses in clinical trials...Despite these innovations, further research is needed to refine manufacturing processes, reduce costs, and improve long-term outcomes. This review emphasizes the transformative potential of CAR-T therapy for pediatric B-ALL and discusses critical challenges and future directions in the field.
By contrast, CARpos T cells obtained from infusion products in long-term responders are enriched in the CD38-CD73-Tim-3-HLA-DR+ phenotype, characterized by a decreased ability to produce adenosine, memory-like transcriptomic characteristics, and leveraging of mitochondrial metabolism and oxidative phosphorylation. Our study reveals that the CD38-CD73-Tim-3-HLA-DR+ phenotype contributes to long-term remission in patients with BCP-ALL who receive tisagenlecleucel.
