TP53 Mutations are Associated with CD19 Negative Relapse and Inferior Outcomes after Blinatumomab in Adults with ALL.

Despite the success of the CD19xCD3 T cell engager blinatumomab in B-cell acute lymphoblastic leukemia (B-ALL), treatment failure is common and can manifest with antigen loss and extramedullary disease (EMD) relapse. To understand the impact of leukemia genetics on outcomes, we reviewed 267 adult patients with B-ALL treated with blinatumomab and used next generation sequencing to identify molecular alterations. Patients received blinatumomab for relapsed/refractory (R/R) disease (n=150), minimal residual disease (MRD+) (n=88), upfront as induction (n=10), or as consolidation in MRD- state (n=19).

Cognitive functioning of older adults prior to hematopoietic stem cell transplantation.

Hematopoietic cell transplantation is increasingly used in older adults with hematological malignancies. Younger adult patients who undergo HCT have shown to commonly present with cognitive impairment and depression prior to transplant; however, little research has been done to understand the cognitive and emotional functioning of older adults undergoing HCT. This study aimed to investigate the rate of cognitive impairment in a retrospective sample of older adult HCT candidates prior to transplant using a comprehensive battery.
