Detailed Description:

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.
