Brief Summary
This research study is looking at biomarkers in DNA samples from patients with acute lymphoblastic leukemia or acute myeloid leukemia. Studying samples of DNA from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.

Outcome Measures
Primary Outcomes (7)
Differences in induction outcome, dichotomized into complete remission or no remission
Assessed with Fisher's exact test.
Up to 8 years
Differences in induction outcome, dichotomized into complete remission or no remission
Assessed with Pearson's chi square statistic test
Up to 8 years
Differences in overall survival
Evaluated using the log rank statistic.
Up to 8 years
Disease-free survival (DFS)
Evaluated using the log rank statistic.
Time from the end of induction to relapse or death, assessed up to 8 years
Relapse-free survival
Evaluated using the logrank statistic.
Time from the end of induction to marrow relapse or death from progressive disease, censoring on deaths from other causes, assessed up to 8 years
Etiology of leukemia: Chi square test
Chi square test will be used to determine the differences in distribution of genotypes between cases and controls.
Up to 8 years
Etiology of leukemia: Fisher's exact test
Fisher's exact test will be used to determine the differences in distribution of genotypes between cases and controls.
Up to 8 years
Study Arms (1)
Ancillary-Correlative (genetic polymorphisms)
Previously collected DNA samples are analyzed for polymorphisms at a variety of loci. Gene expression and expression profiles are correlated with genotype and therapy outcomes.

Eligibility Criteria
You may qualify if:
- DNA samples available from patients meeting the following criteria:
- Infants with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML)
- Patients with pre-B ALL, including responders vs non-responders in selected genotypes \[hyperdiploid, hypodiploid, t(12;21), t(9;22), t(1;19), and t(4;11)\] and responders and non-responders regardless of genotype
- Pediatric patients with AML registered on POG-9421
- Adult patients with ALL, including t(8.21), inv(16), t(15;17), complex cytogenetics, and secondary AML
- Pediatric patients with relapsed ALL enrolled on COG-AALL01P2
- Pediatric patients enrolled on COG-9900 and other CCG or POG trials
