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).

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).

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).

Leslie S. Kean, MD, PhD, of Dana-Farber/Boston Children's Cancer and Blood Disorders Center, discusses findings from her analysis of the International Blood and Marrow Transplant Research Database, which led to the recent FDA approval of abatacept for the prevention of acute graft-vs-host disease (GVHD) in adult and pediatric patients. The data suggest improved overall survival with the immunosuppressant abatacept in combination with a calcineurin inhibitor and methotrexate following 7/8 HLA–matched unrelated allogeneic hematopoietic stem cell transplantation (Abstract 3912).

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).

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).
