Identifying Cancer Genes in in Blood and Bone Marrow Samples From Patients With Acute Myeloid Leukemia

OBJECTIVES: * To identify and validate individual genes for diagnosis of three major translocations in acute myeloid leukemia. * To correlate transcript expression data in the various translocations with age, sex, race, response to treatment, and survival and with other known mutations. OUTLINE: Blood and/or bone marrow samples previously procured from patients on CALGB-9665 are obtained from the CALGB Leukemia Tissue Bank from patients enrolled on CALGB AML treatment studies. Mononuclear cells are isolated from samples and mRNA is extracted. Gene expression profiles are analyzed via custom mRNA microarray and confirmed by quantitative real-time PCR.
