We reviewed the reports of 784 consecutive patients admitted to our department for newly diagnosed acute myeloid leukemia (AML) over a 16-year period. Median, 5-year and 10-year overall survivals were 9.5 months, 17.3% and 11.7% respectively. Induction treatment (698 patients) resulted in 50% complete remissions (CR) (from 26.5% in secondary AML to 81.2% in patients Ͻ60 years with de novo AML). Period of diagnosis (1980-84/85-89/90-95) demonstrated a major significance for CR achievement and OS in multivariate analysis. In patients у60 years (372), CR rate increased (25% to 36.8%, P = 0.03), and 5-year OS (3.7% to 10.6%, P = 0.022) improved, probably due to an increase in the proportion of patients administered conventional combined chemotherapy (54.5% to 83.8%, P Ͻ 0.0001). In younger patients CR rate continuously increased (61.5% to 74.8%, P = 0.028) with an associated improvement of 5-year OS (19.2% to 35.4%). No significant change in DFS and CR durations was observed. This large single center study on a large cohort of unselected AML patients reflects the improvement achieved in the management of AML patients, likely due to improvement of supportive care practices, administration of conventional induction to more elderly patients, and intensification of induction and post-remission treatments in patients Ͻ60 years.
