A six-gene leukemic stem cell score identifies high risk pediatric acute myeloid leukemia.


ABSTRACT: Recently, mRNA-expression signature enriched in LSCs was used to create a 17-gene leukemic stem cell (LSC17) score predictive of prognosis in adult AML. By fitting a Cox-LASSO regression model to the clinical outcome and gene-expression levels of LSC enriched genes in 163 pediatric participants of the AML02 multi-center clinical trial (NCT00136084), we developed a six-gene LSC score of prognostic value in pediatric AML (pLSC6). In the AML02 cohort, the 5-year event-free survival (EFS) of patients within low-pLSC6 group (n?=?97) was 78.3 (95% CI?=?70.5-86.9%) as compared with 34.5(95% CI?=?24.7-48.2 %) in patients within high-pLSC6 group (n?=?66 subjects), p?
