| Summary: | Acute myeloid leukemia (AML) patients exhibit diverse molecular and cytogenetic changes with heterogeneous outcomes. The functionally-derived LSC17 gene expression score has demonstrated strong prognostic significance in retrospective analyses of adult and pediatric AML cohorts, where above-median scores are associated with worse outcomes compared to below-median scores in intensively-treated patients. Here we used a laboratory-developed clinically-validated NanoStringbased LSC17 assay to test the prognostic value of the LSC17 score in a prospective multicentre study of 276 newly-diagnosed AML patients. Each patient’s score was classified as high or low by comparison to a previously-established reference score. In the entire cohort, a high LSC17 score was associated with poor risk features, including advanced age and unfavorable genetic mutations. In the subset of 190 patients treated intensively, a high LSC17 score was associated with lower remission rates (63% vs 94% after induction, P |
