Roni Shouval, MD, PhD, on TP53-Mutant Large B-Cell Lymphoma and CAR T-Cell Therapy
2021 ASH Annual Meeting & Exposition
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).

Eunice S. Wang, MD, of Roswell Park Comprehensive Cancer Center, discusses phase III results showing that gilteritinib and azacitidine led to significantly higher composite complete response rates in patients with newly diagnosed FLT3-mutant acute myeloid leukemia who are ineligible for intensive induction chemotherapy. Overall survival was similar to that of azacitidine alone (Abstract 700).

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).

Anil Aktas-Samur, PhD, of Dana-Farber Cancer Institute, discusses study findings on the genomic characterization of non-progressor smoldering multiple myeloma, results that may provide a molecular definition of the disease as well as its risk-driving features. Combining this low-risk model with current high-risk models may possibly improve clinical trials for patients with this early precursor to myeloma (Abstract 545).

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).

Nikhil C. Munshi, MD, PhD, of Dana-Farber Cancer Institute, discusses the findings from a large nationwide Veterans Affairs study, which showed that, for patients with multiple myeloma, the effectiveness of the COVID-19 vaccine is reduced, likely due to patients’ immunosuppression. Dr. Munshi describes what next steps should be taken (Abstract 400).
