Abdul Rahman Al Armashi, MD, on AML: Racial Disparities in Mortality Trends
2022 ASH Annual Meeting and Exposition
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).

AML is one of the most prevalent forms of acute leukemia. Despite treatment advances, the High V relative survivor rate still has an eerie percent. In the recent data published by the National Cancer Institute, the death threat didn't show any improvement from 1992 to 2020. We conducted a retrospective analysis evaluating the race-specific mortality trends in an old patient with AML in the United States, giving the vacuity of studies evaluating those disparities. We used the CDC Wonder database which contained national mortality and population data. Also, it includes the cause of death from all death certificates filed in the United States. Our population included all patients who died from AML. We also included all races and ethnic groups in the United States from 2000 to 2019. Age-adjusted mortality was calculated per 1 million per person stratified by race and standardized to the US census of 2000. In our study, we found that the age-adjusted mortality was increased equally in both white and black groups.
Also, we found that the mortality trends increased dramatically in the Asian Pacific Islander Group by 25%. It decreased in the Native Americans by 29%. Also, we found that the mortality trends increased by 5% in Hispanics and 3% in non-Hispanic. To our knowledge, this is the largest real-world data study evaluating race and ethnicity specific mortality trends of AML. Multiple variables might contribute to those disparities, including genetics, risk factors, socioeconomic status, equal access to healthcare, and also a response to treatment. Further studies are needed to evaluate those factors and to develop a method to close this gap.

Tomohiro Aoki, MD, PhD, of the University of British Columbia and the Centre for Lymphoid Cancer at BC Cancer, discusses a novel prognostic model applicable to patients with relapsed or refractory classical Hodgkin lymphoma who were treated with autologous stem cell transplantation. The model has shown the interaction between the biomarker CXCR5 on HRS cells (Hodgkin and Reed/Sternberg cells, hallmarks of Hodgkin lymphoma) with specific follicular T helper cells and macrophages, a prominent crosstalk axis in relapsed disease. This insight opens new avenues to developing predictive biomarkers (Abstract 71).

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).

Andrew Matthews, MD, of the Abramson Cancer Center, University of Pennsylvania, discusses findings from a large, multicenter study that showed superior outcomes with 7 + 3 chemotherapy (cytarabine continuously for 7 days, along with short infusions of an anthracycline on each of the first 3 days) vs venetoclax in patients with acute myeloid leukemia (AML). In this real-world data set, the 7 + 3 cohort outperformed historical benchmarks in overall survival and early mortality, perhaps reflecting improved later lines of therapy and patient selection. Prospective studies (such as NCT04801797) must confirm the superiority of intensive chemotherapy (Abstract 426).

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).

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).
