Masayuki Umeda, MD, on Pediatric AML: Identifying a Key Subtype-Defining Lesion
2021 ASH Annual Meeting & Exposition
Masayuki Umeda, MD, of St. Jude Children's Research Hospital, discusses his research which showed that UBTF-TD (upstream binding transcription factor-tandem duplications) define a unique subtype of acute myeloid leukemia that previously lacked a clear oncogenic driver. UBTF-TD is associated with FLT3-ITD and WT1 mutations, adolescent age, and poor outcomes. These alterations are critical for future risk-stratification for this patient cohort.

Musa Yilmaz, MD, of The University of Texas MD Anderson Cancer Center, discusses study results suggesting that quizartinib with decitabine and venetoclax is active in patients with FLT3-ITD–mutated acute myeloid leukemia and that RAS/MAPK mutations continue to drive primary and secondary resistance (Abstract 370).

Leslie S. Kean, MD, PhD, of Dana-Farber/Boston Children's Cancer and Blood Disorders Center, discusses findings from her analysis of the International Blood and Marrow Transplant Research Database, which led to the recent FDA approval of abatacept for the prevention of acute graft-vs-host disease (GVHD) in adult and pediatric patients. The data suggest improved overall survival with the immunosuppressant abatacept in combination with a calcineurin inhibitor and methotrexate following 7/8 HLA–matched unrelated allogeneic hematopoietic stem cell transplantation (Abstract 3912).

Tycel Phillips, MD, of the Rogel Cancer Center, University of Michigan, discusses phase II findings from the CITADEL-204 study of parsaclisib, a next-generation inhibitor of phosphatidylinositol 3-kinase. The agent, used as a monotherapy, appeared to benefit patients with relapsed or refractory marginal zone lymphoma who had a rapid and durable clinical response (Abstract 44).

Roni Shouval, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses his findings, which show, for the first time, that TP53 alterations are a valuable prognostic and potentially predictive marker in patients with large B-cell lymphoma who receive CD19–CAR T-cell therapy. Gene-expression profiling suggests that TP53 alterations result in an immunosuppressive tumor microenvironment and impaired apoptosis signaling, which could lead to decreased CAR T-cell therapy efficacy (Abstract 710).

Andrew Matthews, MD, of the Abramson Cancer Center, University of Pennsylvania, discusses findings from a retrospective study at an academic institution, which showed there was no statistically significant difference in overall survival between induction with CPX-351 and venetoclax/azacitidine for adults with acute myeloid leukemia. Prospective studies to confirm similar effectiveness with careful attention to side effects, quality of life, and impact on transplant outcomes may help clinicians decide between these therapies (Abstract 795).
