Pediatric acute myeloid leukemia with genetic alterations.
Annually, it is estimated that approximately 150-200 children aged 0-16 years are diagnosed with acute myeloid leukemia (AML). In Japan, clinical studies with ANLL91, AML99, CCLSG-AML9805, and JPLSG-AML05 protocols were performed historically, and the risk stratification with a combination of chemotherapy and hematopoietic stem cell transplantation resulted in the improvement of clinical outcomes. Regarding the onset of pediatric AML at the molecular level, mutations in FLT3-ITD or KIT (Class I mutation) showed a poor prognosis, but the ratio of mutations in Class III-V genes was smaller than that in adult AML. In contrast, several pediatric AML cases are complicated due to chromosome fragility syndrome or congenital bone marrow failure syndrome. To improve the clinical outcomes, clinical application of next generation sequencing may allow for personalized therapy in each patient in the future.
