Brief Summary:

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer.

PURPOSE: This research study is studying biomarkers in samples from patients with acute lymphoblastic leukemia enrolled on ECOG-2993 clinical trial.

Condition or disease Intervention/treatment
Leukemia Genetic: RNA analysis Genetic: cytogenetic analysis Genetic: microarray analysis Other: laboratory biomarker analysis

Detailed Description:


  • To identify microRNAs that behave as oncogenes or as tumor suppressor genes in B-lineage acute lymphoblastic leukemia (ALL) in vitro and in vivo.
  • To examine if single microRNA or signatures of microRNA correspond to different clinical outcomes in cytogenetically distinct B-ALL groups.

OUTLINE: RNA from archived samples are analyzed for microRNA expression profile in vitro and in vivo.
