Biomarkers in Tissue Samples From Young Patients With Acute Myeloid Leukemia
Promoter Methylation in MLL-Rearranged Childhood AML

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.


  • 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.

Observational Model: Case-Only
Time Perspective: Retrospective
Not Provided
Retention:   Samples With DNA
