title: Managing therapy in older adult patients with acute myeloid leukemia.
abstract: Acute myeloid leukemia (AML) is predominantly a disease of older adults, with more than 50% of cases occurring in adults over 60 years of age. Treatment of AML in older adults is complicated not only by comorbidities that are common in this patient population, but also by the prevalence, in this age group, of forms of AML with a poor prognosis. The problems encountered and the strategies that have been used to improve the outlook in older adults with AML are presented. The two main strategies for improving outcomes in older adults with AML are to develop effective chemotherapeutic regimens with improved tolerability, and to reduce drug resistance. In studies to identify optimal chemotherapeutic regimens in older adults, a satisfactory balance between efficacy and toxicity has not yet been achieved. Also, the use of growth factors to promote hematopoietic recovery has yet to yield consistent reductions in treatment-related morbidity or mortality. Drug resistance can be modified by inhibiting drug efflux mechanisms or by increasing sensitivity to cytotoxic agents, but these strategies have not yet been shown to significantly affect outcomes. Novel approaches including antibody-targeted and molecular-targeted chemotherapy may have the potential to improve the prognosis for older adults with AML.
