RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is looking at biomarkers in tissue samples from young patients with acute myeloid leukemia previously enrolled on clinical trial POG-9421.

Condition Intervention
Genetic: gene expression analysis
Genetic: microarray analysis
Genetic: proteomic profiling

Primary Outcome Measures:
  • Profiling of basal and potentiated phospho-protein networks (PPPNs) using tissue samples [ Designated as safety issue: No ]
  • Classification of AML-based signal transduction mechanisms [ Designated as safety issue: No ]
  • Correlation of basal and PPPN profiles with specific molecular lesions (e.g., FLT3-ITD, NPM, WT1, c-kit, CEPBα, PASGΔ75, and karyotype) and gene expression profiles. [ Designated as safety issue: No ]

Estimated Enrollment: 90
Study Start Date: October 2009
Estimated Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • To profile basal and potentiated phospho-protein networks (PPPNs) using tissue samples from pediatric patients with de novo acute myeloid leukemia (AML) previously enrolled on clinical trial POG-9421.
  • To classify AML-based signal transduction mechanisms.
  • To correlate profiles of basal and PPPNs with specific molecular lesions (e.g., FLT3-ITD, NPM, WT1, c-kit, CEPBα, PASGΔ75, and karyotype) and profiles of gene expression in tumor tissue samples.

OUTLINE: Banked tissue samples are collected for laboratory studies, including phospho-protein signaling and gene expression profiling studies.
