Childhood Acute Myeloid Leukemia/Other Myeloid Malignancies Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Children with Down Syndrome

continued...

For children with Down syndrome who develop AML, outcome is generally favorable.[18] The prognosis is particularly good (EFS exceeding 80%) in children aged 4 years or younger at diagnosis, the age group that accounts for the vast majority of Down syndrome patients with AML.[19] Appropriate therapy for these children is less intensive than current AML therapy, and hematopoietic stem cell transplant is not indicated in first remission.[3,17,19,20,21,22,23,24]

Children with mosaicism for trisomy 21 are recommended to be treated similarly to those children with clinically evident Down syndrome.[10] Children with Down syndrome who are older than 4 years have a significantly worse prognosis.[21] Although an optimal treatment for these children has not been defined, they are usually treated on AML regimens designed for children without Down syndrome.
