Eunice S. Wang, MD, on AML: Gemtuzumab Ozogamicin Plus Standard Induction Chemotherapy Improves Outcomes
2022 ASH Annual Meeting and Exposition
Eunice S. Wang, MD, of Roswell Park Comprehensive Cancer Center, discusses the outcomes of patients newly diagnosed with acute myeloid leukemia (AML) who were treated with cytarabine plus daunorubicin plus gemtuzumab ozogamicin (GO). These patients experienced higher rates of measurable residual disease–negative complete remission and complete remission with incomplete count recovery, compared to those treated with cytarabine plus idarubicin daunorubicin alone. Although adding GO was not associated with improved overall survival, longer follow-up is warranted to determine an absolute survival advantage of this regimen (Abstract 58).

Stephen M. Ansell, MD, PhD, and Patrizia Mondello, MD, PhD, both of the Mayo Clinic, discuss the 20% of patients with follicular lymphoma (FL) who relapse early and experience a poor prognosis. The researchers found that FLs with high levels of IRF4 expression are associated with a suppressive tumor microenvironment, and selective IRF4 silencing restores antilymphoma T-cell immunity. Further investigation is warranted to identify the mechanisms by which IRF4 controls tumor immunity to develop precision therapies for this population (Abstract 70).

Anand P. Jillella, MD, of Georgia Cancer Center at Augusta University, discusses results from the ECOG-ACRIN EA9131 Trial, which showed that using a simplified treatment algorithm and management recommendations made by a group of specialists, resulted in a dramatic improvement in 1-year survival of patients with acute promyelocytic leukemia (Abstract 421).

Joseph Schroers-Martin, MD, of Stanford University, discusses immunogenomic features reflecting divergent biology in posttransplant lymphoproliferative disorders (PTLD). These include evidence of mismatch repair defects in Epstein-Barr virus–positive PTLD, tumor microenvironment depletion, and MYC pathway enrichment in certain patients (Abstract 72).

Kathryn R. Tringale, MD, of Memorial Sloan Kettering Cancer Center, discusses an assessment of 559 patients with primary central nervous system (CNS) lymphoma and the factors associated with consolidation therapy selection, outcomes after consolidation therapy accounting for patient factors, and patterns of disease failure. The initial treatment response was prognostic and predictive of relapse patterns (Abstract 557).

Julie Côté, MD, of CHU de Québec–Université Laval, discusses findings from the Canadian Myeloma Research Group database, which showed that integrating bortezomib and lenalidomide into the autologous stem cell transplant (ASCT) sequence produces a median overall survival rate ≥ 10 years in most patients with newly diagnosed multiple myeloma. These observations highlight the contribution of post-ASCT maintenance, particularly lenalidomide given until disease progression, when used in multiple patient groups including those with and without high risk, as well as those requiring a second induction regimen (Abstract 117).
