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).

Paolo Ghia, MD, PhD, of the Università Vita-Salute San Raffaele and IRCCS Ospedale San Raffaele, discusses disease-free survival results from the measurable residual disease cohort of the phase II CAPTIVATE trial. This multicenter trial focuses on first-line ibrutinib plus venetoclax in patients with chronic lymphocytic leukemia (Abstract 68).

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).

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.

Romanos Sklavenitis-Pistofidis, MD, of Dana-Farber Cancer Institute, discusses study findings on a next generation of clinical assays to assess both tumor biology and immune state, as well as common clinical biomarkers in the marrow or blood. These biomarkers may accurately predict which patients with smoldering multiple myeloma might benefit from early treatment, monitor response to immunotherapy, and improve patient outcomes (Abstract 330).
