Study Description

Brief Summary: RATIONALE: Studying samples of bone marrow and blood 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 laboratory study is looking at DNA in bone marrow and blood samples from young patients with acute myeloid leukemia or acute lymphoblastic leukemia.

Detailed Description: OBJECTIVES: * Characterize the clinical, morphologic, immunologic, cytogenetic, and molecular heterogeneity of acute lymphoblastic leukemia or acute myeloid leukemia (AML) in infants and monoblastic variants of AML in young patients. * Characterize the clinical, morphologic, immunologic, cytogenetic, and molecular heterogeneity of secondary AML in young patients. * Compare secondary AML vs de novo AML at the level of Southern blot, breakpoint sequence, and DNA topoisomerase II cleavage sites. OUTLINE: This is a multicenter study. Bone marrow or blood are collected and analyzed by Southern blot for chromosome 11q23 breakpoints and translocations. Samples from patients with secondary acute myeloid leukemia are also examined for MLL gene rearrangements. PROJECTED ACCRUAL: A total of 250 patients will be accrued for this study.
