Acute Myeloid Leukemia in the Elderly: A Unique Disease
November 17, 2006
Acute myeloid leukemia (AML) is a disease of the elderly, with the majority of patients diagnosed in their 6th and 7th decade of life. Older patients with AML are less likely to achieve complete remission after induction chemotherapy, and they suffer from higher rates of leukemia relapse compared to younger cohorts. Suboptimal outcomes are the result of adverse biologic characteristics of leukemia in the elderly, as well as the presence of medical comorbidities and patient or physician preferences as to initiating treatment. In addition, there is a distinct lack of randomized, prospective data to guide management decisions for the treatment of AML in the elderly. Patients who are over age 75, with poor performance status, multiple comorbidities, or poor prognostic features, should be considered for a clinical trial or palliative therapy. Elderly patients who are candidates for standard induction chemotherapy and achieve complete remission are unlikely to benefit from intensive postremission therapy and should be referred to a clinical trial when possible. Further prospective trials are needed to identify a tolerable, effective treatment regimen for older patients with AML.
