Prognostic Impact of Somatic Copy Number Alterations in Childhood B-Lineage Acute Lymphoblastic Leukemia

AbstractPurpose of ReviewThe high prevalence of relapse in pediatric B-lineage acute lymphoblastic leukemia (B-ALL) despite the improvements achieved using current risk stratification schemes, demands more accurate methods for outcome prediction. Here, we provide a concise overview about the key advances that have expanded our knowledge regarding the somatic defects across B-ALL genomes, particularly focusing on copy number alterations (CNAs) and their prognostic impact.Recent FindingsThe identification of commonly altered genes in B-ALL has inspired the development of risk classifiers based on copy number states such as theIKZF1plus and the United Kingdom (UK) ALL-CNA classifiers to improve outcome prediction in B-ALL.SummaryCNA-risk classifiers have emerged as effective tools to predict disease relapse; though, their clinical applications are yet to be transferred to routine practice.
