Given the poor outcome of refractory and relapsing T-ALL, identifying prognostic markers is still challenging. Using SNP-array analysis, we provide a comprehensive analysis of genomic imbalances in a cohort of 317 newly-diagnosed T-ALL patients including 135 children and 182 adults with respect to clinical and biological features and outcomes. SNP-array results identified at least one somatic genomic imbalance in virtually all T-ALL patients (~96%). Del(9)(p21) (~70%) and UPD(9)p21)/CDKN2A/B (~28%) were the most frequent genomic imbalances...
