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).

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).

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).

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).

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).

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).
