[Therapy of acute myeloid leukemia in the elderly patient]

Incidence and mortality rates of acute myeloid leukemia (AML) increase exponentially with advancing age. AML diagnosed in elderly patients differs from that diagnosed in younger patients. But not only disease-specific differences are important. Treating elderly patients with AML age-associated differences in the patients general presentation, such as physiological changes in organ function, decreased ability to react to stress, dependence in activities of daily living, existence of other morbidities (co-morbidity), the need to take drugs for those diseases and the reduced life expectancy can force alterations in the disease management. Clinical trials for the treatment of AML have been excluding elderly patients for years. Even trials accepting elderly patients with AML did select the group of otherwise healthy elderly patients for participation in the trial. Thus the data for AML management in elderly patients do not reflect the whole group of elderly patients with AML. If the patient is treated with curative intention, therapy of choice is the so-called 3 + 7 protocol for induction of complete remission, followed by a consolidation therapy and in some cases by maintenance therapy. In some situations, especially in very old patients, a palliative intention to treatment is favored. There are no generally accepted criteria to measure treatment benefit in this setting nor established chemotherapy protocols for this situation. Further trials for elderly patients with AML have to offer treatment options for the whole group of patients and have to determine what treatment approach is the best for which individual patient.
