Molecular Landscape of Acute Myeloid Leukemia in Pediatric Patient-Age-Related Correlations: A Systematic Review.

Acute myeloid leukemia (AML) accounts for 15-20% of childhood leukemia cases; however, it is characterized by very high aggressiveness and has the highest mortality rate among leukemias, with relapse rates ranging from 34% to 38%. It is a disease characterized by high molecular diversity, and the frequency of specific genetic alterations in children is different from that in adults. Furthermore, mutations and rearrangements vary with age within the pediatric population. To date, a wide spectrum of genetic alterations has already been studied, but the molecular landscape of each patient is unique. An analysis of rearrangements and mutations specific to children of different ages appears to be crucial in order to individualize diagnosis and therapy appropriately. The aim of the following review is to analyze the molecular landscape of pediatric AML by age in detail in order to prioritize therapeutic strategies dedicated to specific age groups.
