Background In patients with acute myeloid leukemia (AML), thepresence or absence of recurrent cytogenetic aberrations isused to identify the appropriate therapy. However, the currentclassification system does not fully reflect the molecular heterogeneityof the disease, and treatment stratification is difficult, especiallyfor patients with intermediate-risk AML with a normal karyotype.
Methods We used complementary-DNA microarrays to determine thelevels of gene expression in peripheral-blood samples or bonemarrow samples from 116 adults with AML (including 45 with anormal karyotype). We used unsupervised hierarchical clusteringanalysis to identify molecular subgroups with distinct gene-expressionsignatures. Using a training set of samples from 59 patients,we applied a novel supervised learning algorithm to devise agene-expressionbased clinical-outcome predictor, whichwe then tested using an independent validation group comprisingthe 57 remaining patients.
Results Unsupervised analysis identified new molecular subtypesof AML, including two prognostically relevant subgroups in AMLwith a normal karyotype. Using the supervised learning algorithm,we constructed an optimal 133-gene clinical-outcome predictor,which accurately predicted overall survival among patients inthe independent validation group (P=0.006), including the subgroupof patients with AML with a normal karyotype (P=0.046). In multivariateanalysis, the gene-expression predictor was a strong independentprognostic factor (odds ratio, 8.8; 95 percent confidence interval,2.6 to 29.3; P<0.001).
Conclusions The use of gene-expression profiling improves themolecular classification of adult AML.
