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).

Eva Hoster, PhD, of Munich University, discusses results from the European MCL Elderly Trial, which confirmed the strong efficacy of rituximab maintenance in minimal residual disease (MRD)-negative patients with mantle cell lymphoma (MCL) after induction. Omitting maintenance based on MRD-negativity is thus discouraged. Considering the short time to progression, more effective treatment strategies should be explored in MRD-positive patients to improve long-term prognosis (Abstract 544).

Jennifer R. Brown, MD, PhD, of Dana-Farber Cancer Institute, discusses phase III findings of the ALPINE study, which showed that zanubrutinib is more efficacious and better tolerated than ibrutinib as a treatment for patients with relapsed or refractory chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). In this first head-to-head comparison of the two BTK inhibitors, the superior progression-free survival of zanubrutinib was observed across all major subgroups, including high-risk patients (Abstract LBA-6).

Paolo F. Caimi, MD, of the Taussig Cancer Institute, Cleveland Clinic, discusses new findings showing that patients with diffuse large B-cell lymphoma (DLBCL) who achieve a complete response after salvage therapy with rituximab, ifosfamide, carboplatin, and etoposide (R-ICE) can achieve long-term disease control, regardless of the time to relapse from initial therapy, particularly if they proceed to autologous stem cell transplant (ASCT). These results suggest that second-line chemotherapy followed by ASCT and/or CAR T-cell therapy for chemosensitive and chemorefractory patients may maximize patient outcomes, regardless of time to relapse (Abstract 156).

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).

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).
