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).

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).

Eileen M. Boyle, MD, PhD, of the Perlmutter Cancer Center, NYU Langone Health, discusses Fc-mediated antibody effector function, inflammation resolution, and oligoclonality and their role in predicting sustained measurable residual disease negativity in patients with newly diagnosed multiple myeloma who were treated with immunotherapy regimens. For the first time, an analysis of T-cell receptors shows that oligoclonal profiles seen on treatment may influence the fitness of the immune response (Abstract 100).

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).

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).

Smita Bhatia, MD, MPH, of the Institute for Cancer Outcomes and Survivorship, University of Alabama at Birmingham, discusses study findings that showed key somatic mutations in the peripheral blood stem cell product increases the risk of developing therapy-related myeloid neoplasms (Abstract 119).
