Integration of artificial intelligence and point-of-care manufacturing may further streamline production and patient selection. Continued innovation will determine the long-term impact of CAR T-cell therapy as a scalable pillar of precision hematologic oncology.

High SFRP1 expression in B-ALL BMSCs suppresses osteogenesis and contributes to bone loss in B-ALL cohorts by inhibiting Wnt/β-catenin signaling, which afford a potential translatable target to reprogram bone homeostasis and prevent bone fragility in ALL patients. Given the negative correlation between SFRP1 overexpression in BMSCs of pediatric B-ALL related bone mass loss, precisely targeting SFRP1 in MSCs for intervention holds promise as a therapeutic strategy to rescue bone loss in this disease category.

TCF3::HLF-positive B-ALL represents an ultra-high-risk leukemia requiring allo-HSCT for long-term remission. CAR-T serves as a bridge to transplantation, while RAS and CD33-directed therapies warrant further investigation. These findings provide critical insights into disease biology and potential treatment.

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.

This model might provide a new strategy to support ex vivo B-cell differentiation using the powerful properties of WJ-MSC. This study implements a new approach to improve understanding of B-leukemogenesis and B-cell acute lymphoblastic leukemia (B-ALL) pathophysiology.

IL-27 constrains B-cell haematopoiesis and B-ALL progression through coordinated progenitor inhibition and BM niche remodelling, revealing a cytokine-driven strategy with the potential to enhance leukaemia therapy.

B-ALL patients who relapse after allo-HSCT may benefit from either donor- or patient-derived CAR T-cell therapy, but the risk of graft-versus-host disease may be higher for donor-derived products.

PDGFRB-rearranged ALL in children is uncommon, is most often detected in B-ALL, and presents at a relatively older age. Fusion partners are diverse and frequently co-occur with additional gene mutations. Despite high initial remission, MRD negativity and molecular clearance rates remain suboptimal, and allogeneic hematopoietic stem cell transplantation may improve prognosis.

For management, we evaluate conventional therapies (corticosteroids, etoposide) and emerging immunomodulatory agents (anakinra, ruxolitinib, emapalumab), emphasizing the 2023 treatment regimen by the American Society of Transplantation and Cellular Therapy (ASTCT). By integrating risk stratification, early diagnostic criteria, and tailored therapeutic approaches, this review aims to improve clinical outcomes for IEC-HS patients.
