S9031-S9126-S9333-S9500-B Biomarker Expression in Patients With Acute Myeloid Leukemia
Topoisomerase 2 Expression and Acute Myeloid Leukemia (AML)
RATIONALE: Studying samples of bone marrow 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 biomarker expression in bone marrow samples from patients with acute myeloid leukemia.

详细说明
OBJECTIVES:
- Estimate the distributions of topoisomerase 2 (TOP2) expression and single nucleotide polymorphisms (SNPs) in patients with newly diagnosed acute myeloid leukemia (AML).
- Estimate the distributions of mutations in TOP2 phosphorylation sites (by SNP analysis) in these patients.
- Investigate whether expression of TOP2 or mutations in TOP2 phosphorylation sites vary with patient or disease characteristics in these patients.
- Test whether TOP2 expression correlates with complete remission rates, relapse-free survival, and overall survival of these patients.
- Conduct preliminary analyses to estimate the distributions of TOP2 expression and mutations in TOP2 phosphorylation sites (by SNP analysis) in patients with relapsed and/or refractory AML.
- Investigate whether expression of TOP2 and mutations in TOP2 phosphorylation sites vary with patient or disease characteristics in patients with relapsed and/or refractory AML.
- Test whether TOP2 expression and mutations in TOP2 phosphorylation sites differ between previously untreated and relapsed/refractory AML patients.
OUTLINE: This is a multicenter study.
Archived RNA specimens are analyzed for topoisomerase 2 transcriptional expression by quantitative real-time polymerase chain reaction (PCR) and for mutations within TOP2 phosphorylation sites by single nucleotide polymorphism analysis.
