Acute Myeloid Leukemia (AML) - Pediatric
Advances in understanding the cytogenetic and molecular abnormalities of acute myelogenous leukemia (AML) have improved the ability to risk stratify both adult and pediatric patients in order to identify those who would benefit most from hematopoietic cell transplantation (HCT).
Pediatric AML is a relatively rare disease, with an incidence of approximately seven cases per million children younger than 15 years. 
Research demonstrates that allogeneic HCT in complete first remission for children and adults with high-risk AML results in outcomes comparable to outcomes of standard-risk patients.  And a 2017 multi-center study found that transplant survival in children with unfavorable karyotype AML has improved significantly over time, and was due to decrease in relapse risk. 
Figure 1 demonstrates how transplant outcomes have steadily improved over time in pediatric patients with AML undergoing unrelated donor transplantation.

Review outcomes for transplants in pediatric patients with AML below. View additional AML slides showing demographic data and transplant trends.
Pediatric AML patients who receive transplants in first or second complete remission (CR) experience significantly improved survival compared to those transplanted with advanced disease (primary induction failure, active disease, or CR3 and beyond).

Referral Timing Guidelines
These guidelines highlight disease categories that include patients at risk for disease progression and who should be referred for a consultation for autologous or allogeneic transplantation. 
Transplant Consultation Guidelines: Pediatric AML
High-resolution HLA typing is recommended at diagnosis for all patients
Early after initial diagnosis, all patients with AML including:
- Age <2 years at diagnosis
- Primary induction failure
- Minimal residual disease after initial therapy
- CR1 – except favorable risk AML [defined as: t(16;16); inv 16; t(8;21); t(15;17); normal cytogenetics with NPM1 or isolated biallelic CEBPA mutation and without FLT3-ITD]
- Monosomy 5 or 7
- Treatment-related leukemia
- First relapse
- CR2 and beyond, if not previously evaluated
