RATIONALE: Studying samples of blood or tumor tissue 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 studying biomarkers in DNA samples from patients with newly diagnosed high-risk acute lymphoblastic leukemia.

Primary Outcome Measures:
  • Identification of loci enriched for genetic variation suggestive of pre-B leukemogenesis [ Designated as safety issue: No ]
  • Correlation between high-risk acute lymphoblastic leukemia with clinical phenotypes, co-morbidities, toxicities, outcomes to the genes or pathways found to harbor a significant increase in genetic variation [ Designated as safety issue: No ]

Estimated Enrollment: 350
Study Start Date: September 2010
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Detailed Description:


  • To perform pooled DNA sequencing in 56 genes from the genomic DNA of unaffected children and matched non-tumor and blast DNA from patients with high-risk (HR) acute lymphoblastic leukemia (ALL) enrolled on COG HR ALL protocols.
  • To identify loci enriched for genetic variation between DNA of unaffected children and DNA of these patients.
  • To individually validate novel, putatively functional single nucleotide polymorphisms (SNPs) identified via pooled sequencing with another genotyping platform.
  • To correlate HR ALL with clinical phenotypes, co-morbidities, toxicities, outcomes to the genes or pathways found to harbor a significant increase in genetic variation.

OUTLINE: DNA specimens from unaffected children (pool 1) and from patients with non-tumor (pool 2) and leukemia blasts (pool 3) are analyzed for genetic pathophysiology of pre-B acute lymphoblastic leukemia by microarray and PCR assays. Sequencing is performed on each of the 3 PCR pools of DNA.
