Alba Rodriguez-Meira, DPhil, on TP53-Mutated Leukemic Transformation in Myeloproliferative Neoplasms
2021 ASH Annual Meeting & Exposition
Alba Rodriguez-Meira, DPhil, of the University of Oxford, discusses a comprehensive analysis of the genetic, cellular, and molecular landscape of TP53-mediated transformation, providing insights into the evolution of chronic hematologic malignancies toward an aggressive acute leukemia. Because TP53 is the most commonly mutated gene in human cancer, these findings may well be of broad relevance (Abstract 3).

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).

Joe Schroers-Martin, MD, of Stanford University, discusses his latest study findings, which show that follicular lymphoma driver mutations are detectable in blood and saliva years prior to a clinical diagnosis. These data build on previous work and suggest that researchers may be able to stratify people at elevated risk of clinical malignancy (Abstract 709).

Manali Kamdar, MD, of the University of Colorado Cancer Center, discusses phase III results from the TRANSFORM study, which suggest that lisocabtagene maraleucel, a CD19-directed CAR T-cell therapy, improved outcomes with a favorable safety profile and may be a potential new standard of care for second-line treatment of patients with relapsed or refractory large B-cell lymphoma (Abstract 91).

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).
