De novo acute myeloid leukemia: A population‐based study of outcome in the United States based on the Surveillance, Epidemiology, and End Results (SEER) database, 1980 to 2017

Several important treatment and supportive care strategies have been implemented over the past 4 decades in the management of acute myeloid leukemia (AML).The authors identified 29,107 patients who were diagnosed with de novo AML between 1980 and 2017 in the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Patients were categorized into 5 age groups (ages birth to 14, 15-39, 40-59, 60-69, and ≥70 years) and 4 calendar periods (1980-1989, 1990-1999, 2000-2009, and 2010-2017). The outcomes of patients who had AML within these categories were analyzed.The overall 5-year survival rates in patients with AML were 9%, 15%, 22%, and 28% in the decades 1980 to 1989, 1990 to 1999, 2000 to 2009, and 2010 to 2017, respectively. Among patients aged 15 to 39 years, the 5-year survival rates were 24%, 41%, 52%, and 63%, respectively; among those aged ≥70 years, the 5-year survival rates were 1%, 2%, 3%, and 5%, respectively. Four-week mortality was surprising high among adults and older patients (range, 20%-45%), even in modern times. Overall, survival continued to improve over the calendar periods and was best in the period from 2010 to 2017. Survival improvement was noticeable across all age groups except patients aged ≥70 years, in whom the estimated 5-year survival rate remained 5% even during the period from 2010 to 2017.The outcomes of patients with AML showed incremental improvement over time in a population-based study of the Surveillance, Epidemiology, and End Results data. The introduction since 2017 of targeted therapies among older patients and optimizations in supportive care hopefully will continue to improve outcomes in AML, particularly among older patients.
