Summary
RATIONALE: Studying samples of bone marrow and blood from patients with cancer who failed treatment may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer resistance. It may also help doctors find better ways to treat cancer.

PURPOSE: This research trial studies biomarkers in samples from adult patients with acute myeloid leukemia who failed standard-of-care treatment.
Detailed Description
OBJECTIVES:

- Define a "non-response" signature that will help up-front identification of cases of intermediate-risk acute myeloid leukemia (AML) destined to fail existing standard-of-care therapy.

- Identify biological pathways in the "non-response" group that can provide targets for novel therapeutics.

OUTLINE: DNA and RNA extracted from cryopreserved bone marrow cells and/or blood cells are analyzed for mutations and gene expression signatures (genome-wide methylation, mRNA and miRNA expression, and single nucleotide polymorphism (SNP) analysis) by microarray assays.
Criteria for eligibility
Healthy Volunteers: No
Maximum Age: 65 Years
Minimum Age: 18 Years
Gender: Both
Criteria: DISEASE CHARACTERISTICS:

- Samples from previously untreated non-M3 acute myeloid leukemia (AML)

- Normal karyotype (NK) intermediate-risk disease

- Two or more vials of cryopreserved pretreatment bone marrow cells and/or two or more vials of cryopreserved pretreatment blood cells available from the Intergroup AML Repository
