Acute myeloid leukemia (AML) is the common form of acute leukemia in adults, accounting for over 80% of all acute leukemias in individuals aged >18 years. Overall 5-year survival remains poor in older AML patients; it is <5% in patients aged >65 years. In this study, the authors examined whether survival has improved for subsets of geriatric AML patients over 3 successive decades.


Surveillance, Epidemiology and End Results (SEER) data were used to determine trends in relative survival by age among 19,000 patients with AML over 3 successive decades (1977-1986, 1987-1996, and 1997-2006). Relative survival rates (RRs) with 95% confidence intervals (CIs) were calculated as measures of survival.


Overall, the RRs increased for each successive decade (1977-1986, 1987-1996, and 1997-2006) in patients ages 65 to 74 years, with improvements in 12-month survival from 20%, to 25%, to 30%, respectively. Findings were similar for 24-month, 36-month, 48-month, and 60-month survival. However, survival rates did not improve in patients aged ≥75 years. The oldest old patients (aged ≥85 years) had the lowest survival rates, with no apparent improvement.


This analysis of a large data set demonstrated that, although overall survival remained unsatisfactory among older patients, it improved in the younger old (ages 65-74 years). Survival of older old AML patients has not been favorably impacted by available AML therapies or supportive care, and intervention in this age group is best undertaken on a clinical trial.
