New Study Finds Higher Likelihood of AML in Children With Down Syndrome
Posted May 10, 2021

A new study published in the March issue of The Journal of Pediatrics found that children with Down Syndrome have an estimated 150-fold higher risk of developing acute myeloid leukemia (AML) before the age of five. 

Dr. Emily Marlow, PhD, from the University of California (UC) Davis led the study which analyzed data of just over 3.9 million children born from 1996-2016 in the United States and Canada. Leukemia was diagnosed in 124 of the 4401 children with Down syndrome (2.8%) and 1941 of 3,900,998 of the other children (0.05%).  

The researchers concluded that Down Syndrome remains a risk factor for the development of childhood AML, and this data shows that the association with AML is stronger than previously reported.

According to Dr. Marlow, “One main strength of this study is its large cohort with more leukemia cases in children with Down syndrome than most previous studies. This allowed more precise risk estimation, especially for rare leukemia types such as AML-7, previously estimated from small case reports.” 

Due to the much higher risk of AML in children with Down Syndrome, it is crucial for parents of these children to understand the signs and symptoms of AML and watch for them, especially during the child’s early years. If identified and treated early, AML in children is often treatable. 

Signs and symptoms of AML include pale skin, fatigue, frequent infections, easy bleeding or bruising and shortness of breath. A prompt visit to a pediatrician is warranted if children exhibit these symptoms.
