RNA sequencing reveals cellular hierarchies impacting prognosis in pediatric acute myeloid leukaemia, suggesting improved treatment strategies.

The research aims to identify cellular hierarchies in pediatric acute myeloid leukaemia (AML) to understand prognostic implications.
Summary RNA sequencing was conducted on 262 pediatric AML patients.
Adult single-cell RNA-sequencing signatures were utilized for deconvolution.
Principal component analysis differentiated pediatric from adult AML based on cellular hierarchies.
Five cellular hierarchy subtypes were identified: primitive, LSPC-Cycle, ProMono-like, GMP-like, and intermediate.
LSPC-Cycle was linked to poor prognosis with a significant overall survival odds ratio of 11.33 against GMP-like.
Mutations such as FLT3-ITD and NUP98::KDM5A were associated with poorer outcomes, emphasizing the need for tailored treatment strategies.

Komori et al. (2026) studied this question.
