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).

Mark R. Litzow, MD, of the Mayo Clinic, discusses phase III results from the ECOG-ACRIN E1910 Trial, which show that adding blinatumomab to consolidation chemotherapy resulted in a significantly better overall survival in adult patients aged 30 to 70 years with newly diagnosed B-lineage acute lymphocytic leukemia (ALL) who were measurable residual disease–negative after receiving intensification chemotherapy. The authors believe this may represent a new standard of care for this population (Abstract LBA-1).

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).

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).

Jia Ruan, MD, PhD, of Meyer Cancer Center, Weill Cornell Medicine, and NewYork-Presbyterian Hospital, discusses trial results demonstrating that the triple chemotherapy-free combination of acalabrutinib, lenalidomide, and rituximab is well tolerated, highly effective, and produces high rates of minimal residual disease (MRD)-negative complete response as an initial treatment for patients with mantle cell lymphoma, including those with TP53 mutations. Real-time MRD analysis may enable treatment de-escalation during maintenance to minimize toxicity, which warrants further evaluation. An expansion cohort of acalabrutinib/lenalidomide/obinutuzumab is being launched (Abstract 73).

Elias Jabbour, MD, of The University of Texas MD Anderson Cancer Center, discusses an analysis confirming that olverembatinib is a potentially viable treatment option for patients with chronic myeloid leukemia (CML) and Philadelphia chromosome–positive acute lymphoblastic leukemia (ALL), including those with CML whose disease did not respond to ponatinib or asciminib, or who had a T315I mutation (Abstract 82).
