title: Chromosomes, Auer rods and prognosis in acute myeloid leukaemia.
abstract: We have analysed survival time and complete remission (CR) rate after induction treatment including cytosine arabinoside and an anthracycline antibiotic in 94 patients with acute myeloid leukaemia, comparing the results in four different groups according to the presence or absence of Auer rods and the presence (AN/AA) or absence (NN) of abnormal cytogenetic clones at diagnosis. The finding of Auer rods was a positive prognostic factor with respect to CR rate (p less than 0.02) and survival time (p less than 0.02) irrespective of the cytogenetic pattern. The AN/AA pattern was associated with lower CR rate (p less than 0.05) and 6-months survival (p = 0.05) in the 49 Auer rod-negative patients. In the 45 patients with Auer rods, no significant differences in CR rate or survival were seen between AN/AA and NN patients. We conclude that the negative prognostic impact of chromosome abnormalities in acute myeloid leukaemia might be restricted to Auer rod-negative disease.
