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.

Sangeetha Venugopal, MD, of The University of Texas MD Anderson Cancer Center, discusses a retrospective analysis of 562 patients with treated secondary acute myeloid leukemia and prior exposure to hypomethylating agents (HMAs). The results showed that an HMA plus venetoclax yielded significantly higher overall response rates and improved overall survival compared with intensive chemotherapy or low-intensity chemotherapy, particularly in patients 60 years or older who had a karyotype without adverse risk (Abstract 794).

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).

Carsten Utoft Niemann, MD, PhD, of Copenhagen University Hospital, discusses a primary analysis of the phase II Vision HO141 trial, which showed the feasibility of stopping and restarting ibrutinib and venetoclax in patients with relapsed or refractory chronic lymphocytic leukemia who have undetectable measurable residual disease. A favorable benefit-risk profile was demonstrated, with no new safety signals (Abstract 69).

Daniel A. Ermann, MD, of the Huntsman Cancer Institute, University of Utah, discusses results from the largest retrospective study on outcomes utilizing radiotherapy in early-stage diffuse large B-cell lymphoma. Adding radiation to front-line multiagent chemotherapy was associated with a survival benefit for all patients with early-stage disease. An overall survival benefit was seen with the addition of radiation to front-line multiagent chemotherapy for patients with nodal involvement and those with specific extranodal involvement in the testes, thyroid, skin and soft tissue, and head and neck (Abstract 49).

Talha Badar, MD, of the Mayo Clinic, discusses the near-universal poor outcomes for patients with TP53-mutated acute myeloid leukemia and the findings that show allogeneic stem cell transplantation appears to improve the long-term survival in a subset of these patients. Effective therapies may successfully bridge patients to transplant and prolong survival for those who are transplant-ineligible (Abstract 797).
