Recruitment status was Not yet recruiting
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.
Genetic: RNA analysis
Genetic: cytogenetic analysis
Genetic: microarray analysis
Other: laboratory biomarker analysis
|Official Title:||Micro RNA Expression Analysis in B-Lineage Adult Acute Lymphoblastic Leukemia From ALL Trial, E2993, Including Patients With Various Cytogenetic and Molecular Abnormalities|
- Comprehensive view of microRNA expression by cytogenetic subgroup [ Designated as safety issue: No ]
- MicroRNA expression in relation to clinical outcome [ Designated as safety issue: No ]
- Differential microRNA expression between normal B-cells and progenitors compared to B-ALL [ Designated as safety issue: No ]
|Study Start Date:||March 2012|
|Estimated Primary Completion Date:||March 2013 (Final data collection date for primary outcome measure)|
- 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.
