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).

L. Elizabeth Budde, MD, PhD, of City of Hope, discusses phase I/II findings that showed mosunetuzumab monotherapy induces deep and durable remissions in patients with relapsed or refractory follicular lymphoma who have received two or more prior lines of treatment, including those with double-refractory disease. Because follicular lymphoma is associated with frequent relapses and decreasing progression-free intervals with successive lines of conventional therapy, these data are encouraging (Abstract 127).

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.

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).

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).
