Elderly patients with acute myeloid leukaemia: characteristics in biology, patients and treatment. Recommendations of the Working Group Geriatric Oncology of the German Society for Haematology and Oncology (DGHO), the Austrian Society for Haematology and Oncology (OGHO) and the German Society for Geriatrics (DGG).
While the incidence rate of acute myeloid leukaemia (AML) is increasing with the age of the patients, the 5-year-survival rates are decreasing in an age-dependent manner. Patients with AML are considered to be old when they have reached the age of 60. This consideration is due to patient- and disease-specific parameters, which reveal differences between older and younger patients with AML. Standard of therapy is a dose-intensive chemotherapy aiming at the induction of complete remission, followed by different kinds of post-remission therapies. A small percentage of patients can be cured by this approach. However, most patients will die within the first 2 years after diagnosis due to resistance or relapse of the disease or therapy-related complications. The improvements achieved in the treatment of patients with AML are mainly restricted to the group of younger patients. The small percentage of patients who are cured, and the high rate of treatment-related mortality in elderly patients with AML give rise to the question which patients benefit from a primarily curative approach, and which should be treated with a palliative approach. The value of a palliative approach has not yet been consistently assessed in clinical trials. Geriatric assessment will be an important tool in clinical trials for elderly patients with AML to be used in the decision making process. There is hope that new classes of drugs and treatment modalities such as inhibitors of signal transduction, monoclonal antibodies, inhibitors of angiogenesis, or allogenic blood stem cell therapy after non-myeloablative conditioning regimens will improve the therapy of elderly patients with AML in the near future.
