Abstract Three sequential trials of treatment for acute myelogenous leukemia (AML) involving 173 patients were analyzed to identify clinical and myeloblast-cell progenitor properties in culture related to outcome. The latter, including self-renewal capacity expressed as plating efficiency (PE2) and drug sensitivity, were determined for a representative group of 45 patients. Despite increasingly intensive remission induction therapy, similar response rates were achieved in the three trials and no increase in the duration of survival was observed. Clinical attributes at presentation by multivariate analyses were not consistently predictable of outcome. Of the blast cell attributes, only PE2 was predictive of duration of survival (p less than 10(-6)). For patients in remission the relapse rate during the first year was 0.63 compared with 0.15 in subsequent years. The percentage marrow myeloblasts at presentation, a measure of disease activity, was significantly higher for the patients having remissions lasting less than one year. These studies demonstrate the importance of disease-related attributes on the outcome of patients with AML.
