RATIONALE: Studying blood samples 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 trial studies biomarkers related to chemotherapy resistance and outcomes in samples from older patients with acute myeloid leukemia.

Condition Intervention
Genetic: DNA methylation analysis
Genetic: RNA analysis
Genetic: gene expression analysis
Genetic: microarray analysis
Genetic: nucleic acid sequencing
Other: laboratory biomarker analysis

Study Type: Observational

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

Primary Outcome Measures:
  • Genetic and epigenetic determinants of chemoresistance and adverse outcomes
  • Perturbed biologic pathways with clinical, prognostic, and therapeutic relevance
  • Identification and validation of lesions and pathways that are highly associated with chemo-sensitive and chemo-refractory disease

Estimated Enrollment: 257
Study Start Date: September 2011
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • Delineate the spectrum of genetic and epigenetic lesions occurring in elderly patients with acute myeloid leukemia (AML).
  • Determine the biological functions perturbed by these lesions.
  • Identify and validate lesions or pathways that are most highly associated with chemo-sensitive and chemo-refractory disease, and with adverse outcome in elderly AML.
  • Identify potential classifiers and biomarker lesions that we can then evaluate prospectively in the E2906 trial which is about to begin enrollment.

OUTLINE: DNA and RNA extracted from cell samples are analyzed for genetic and epigenetic expression by Agilent SureSelect sequencing, Illumina HiSeq2000 platform coding and sequencing, DNA methylation, and microarray assays. Results are then associated with patients' overall survival, progression-free survival, and complete response rate. Results are also analyzed assessing the prognostic relevance of known mutations and epigenetic alterations that have shown to have an impact on overall survival and response to therapy in younger patients with acute myeloid leukemia (AML) in E1900 including, but not limited to, FLT3, DNMT3A, IDH1, IDH2, TET2, ASXL1, WT1, and MLL, and 15-gene DNA methylation classifier, and with novel recurrent mutations identified by other AML-profiling efforts.
