Elderly patients with acute myeloid leukemia who only receive supportive care in the Surveillance, Epidemiology and End Results-Medicare database: demographics, treatment patterns and outcomes.

This study analyzed data on elderly patients with acute myeloid leukemia (AML) who were only treated with supportive care. The source of this data was the Surveillance, Epidemiology and End Results (SEER)-Medicare database. Of the 7665 patients diagnosed with AML during 2008­2015, 3209 (41.9%) received supportive care only. Their mean age at index date was 79 years; slightly more than half of these were males (50.5%). Almost half of these patients (48.2%) died within the first 3 months and approximately two-thirds (67.3%) died within the first 6 months. Only a small proportion (13%) of these patients were alive after 1 year. These patients who were alive after one were likely to be in remission (there was decrease in the signs and symptoms of AML). The results of this study showed that elderly AML patients who only received supportive care were more likely to die early if they also had chronic kidney disease, chronic obstructive pulmonary disease, history of acute myocardial infarction or hypertension. As elderly AML patients may be in poor general health and have other diseases (comorbidities), this could be the reason why they may not be treated with antileukemic therapy. Instead of treatment with supportive care only, these patients should ideally receive antileukemic therapy in addition to supportive care. More research should be done to find alternate treatments for these elderly AML patients.
