Talha Badar, MD, on TP53-Mutated AML and the Impact of Allogeneic Stem Cell Transplantation on Survival
2021 ASH Annual Meeting & Exposition
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).

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).

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.

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).

L. Elizabeth Budde, MD, PhD, of City of Hope, discusses phase I/II findings that showed mosunetuzumab monotherapy induces deep and durable remissions in patients with relapsed or refractory follicular lymphoma who have received two or more prior lines of treatment, including those with double-refractory disease. Because follicular lymphoma is associated with frequent relapses and decreasing progression-free intervals with successive lines of conventional therapy, these data are encouraging (Abstract 127).

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).
