We illustrate four use cases of ASHOP: (1) stratification of DUX4-rearranged B-cell leukemias into Early/Multipotent and Committed subgroups with distinct outcomes, (2) characterization of HOXA/HOXB expression patterns in acute myeloid leukemias, (3) correlating mutational burden with mismatch repair deficiency and mutational signatures, (4) investigation of TP53 alteration landscape. ASHOP is an open-access resource to inform genomic and transcriptomic data interpretation for hematologic malignancies, and will expand to support additional diseases and data modalities from the ASH community.

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.

NUDT15 deficiency is furthermore prevalent on the Western coast of South and Central America but absent in Africa. Overall, our results provide a valuable resource for population-specific NUDT15 allele and metabolizer phenotype distributions, which can guide thiopurine risk assessment on a global scale.

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.

Here, we analyzed the sensitivity of T-ALL to inhibitors of BCL-2 (venetoclax), BCL-XL (A1331852), MCL-1 (AZD5991) and dual inhibition of BCL-2/BCL-XL (AZD4320) and evaluated their combination effects with natural killer (NK) cells. Importantly, NK cell-mediated killing could be further enhanced by combining NK cells with AZD4320, proposing this combination as a potential effective treatment. Taken together, we demonstrated promising potential of BH3-mimetics and NK cells for the treatment of T-ALL alone and in combination, warranting further preclinical and potential clinical evaluation.

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.
