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).

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).

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).

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).

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).

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).
