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).

Abdul Rahman Al Armashi, MD, of Seidman Cancer Center, Case Western University, University Hospitals Cleveland Medical Center, discusses a retrospective analysis, using a CDC database, in one of the largest subgroup-based racial population studies analyzing mortality trends in patients with acute myeloid leukemia (AML). Between 2000 and 2019, AML mortality was the highest in Whites and the lowest in American Indians or Alaska Natives. The highest rate of increase in mortality was seen in Asians or Pacific Islanders. Dr. Al Armashi talks about the many variables that might contribute to these inequalities (Abstract 600).

Alex F. Herrera, MD, of the City of Hope National Medical Center, discusses results from the POLARIX study, which showed that circulating tumor DNA (ctDNA) analysis has prognostic value for patients with previously untreated diffuse large B-cell lymphoma. Patients who did not achieve 2.5 or greater log-fold change and/or did not have ctDNA clearance following one cycle of polatuzumab vedotin along with rituximab, cyclophosphamide, doxorubicin, and prednisone had inferior outcomes than those who did. Early changes in ctDNA levels may be of use in risk-adapted trial designs to identify patients in need of alternative treatment. (Abstract 542).

Jiye Liu, PhD, of Dana-Farber Cancer Institute, discusses study findings that demonstrate KDM6A regulates CD38 and CD48 expression in multiple myeloma. Dr. Liu’s team validated combination treatment with an FDA-approved EZH2 inhibitor plus daratumumab, which can overcome daratumumab resistance in preclinical multiple myeloma models, providing the rationale for combination clinical trials to improve patient outcome (Abstract 148).

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).

Tycel J. Phillips, MD, of the City of Hope National Medical Center, discusses data that showed fixed-duration glofitamab monotherapy induced high and durable complete response rates in patients with mantle cell lymphoma (MCL) who received obinutuzumab pretreatment. This is one of the largest data sets and longest follow-ups reported with a CD20/CD3 bispecific monoclonal antibody for patients with relapsed or refractory MCL (Abstract 74).
