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

PURPOSE: This research study is studying biomarkers in tissue samples from young patients with acute myeloid leukemia.

Condition Intervention
Genetic: DNA methylation analysis
Genetic: gene expression analysis
Genetic: microarray analysis
Genetic: reverse transcriptase-polymerase chain reaction

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Identification of differential patterns of promoter hypermethylation and gene expression in pairwise comparisons with other cohorts and normal controls [ Designated as safety issue: No ]

Estimated Enrollment: 32
Study Start Date: November 2010
Estimated Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • To determine whether the pattern of global and TSG-specific promoter CpG island hypermethylation and gene silencing that we have shown characterizes MLL-rearranged (MLL-r) infant bilineage ALL is also characteristic of other subsets of MLL-r leukemia.

OUTLINE: Previously collected cryopreserved cells from diagnosis are analyzed for promoter methylation via HELP arrays, gene expression arrays, and RT-qPCR.

PROJECTED ACCRUAL: A total of 32 samples (8 from each of 4 biologically defined cohorts) will be analyzed.
