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).

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).

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).

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).

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).

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).
