Further study details as provided by Eastern Cooperative Oncology Group:

Primary Outcome Measures:
  • Comprehensive view of microRNA expression by cytogenetic subgroup [ Time Frame: 1 year ]
  • MicroRNA expression in relation to clinical outcome [ Time Frame: 1 year ]
  • Differential microRNA expression between normal B-cells and progenitors compared to B-ALL [ Time Frame: 1 year ]

Enrollment: 186
Actual Study Start Date: January 6, 2012
Study Completion Date: February 6, 2012
Primary Completion Date: February 6, 2012 (Final data collection date for primary outcome measure)
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.
