Acute myeloblastic leukaemia in the elderly.

Acute myeloblastic leukaemia (AML) is a disease of the elderly with a median age at presentation in the seventh decade and a peak incidence in the U.K. of greater than 20 patients per 100,000 population per yr between the ages of 80 and 84. Most major AML trials are carried out on a younger population of patients with low recruitment of the elderly. The results in older patients are much worse than younger patients and often no better than the natural history of the disease. These poor results may be partly due to poor tolerance of treatment in the elderly, but are also due to intrinsic differences between AML in the elderly and AML in younger patients. These problems all justify randomised, prospective trials designed specifically for elderly patients to test prognostic scoring and various levels of intensity of therapy.
