title: The treatment of acute myeloid leukaemia preceded by the myelodysplastic syndrome.
abstract: Most cases of acute myeloid leukaemia in the elderly and about 15% of the cases in younger patients follow a myelodysplastic disease. This disease may differ biologically from de novo AML making cure more difficult. Understanding post-MDS AML is difficult because of its preponderance in the elderly and the many complicating factors of treating old people. However, it is likely that post-MDS AML is more resistant to chemotherapy than de novo AML, that periods of pancytopenia last longer following chemotherapy and remissions are shorter. In younger patients high complete remission rates are achievable with aggressive chemotherapy and good supportive care. Such patients are best served by subsequent allogeneic bone marrow transplantation if possible, and if not then bone marrow autograft or a maintained remission should be considered. For older patients cure is unlikely and the choice between low-dose cytarabine and aggressive chemotherapy must be made if treatment is to be contemplated at all. The former leads to less hospitalisation and fewer side effects, but the latter gives a greater chance of a complete remission. This will not be long lasting.
