Further study details as provided by Children's Oncology Group:

Primary Outcome Measures:
  • Frequency of AML that originate in CD33+ or in which uncontrolled growth is restricted to CD33+ precursors [ Designated as safety issue: No ]
  • Extent of clonal hematopoiesis in small numbers of AML cells [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Estimated Enrollment: 20
Study Start Date: October 2010
Estimated Primary Completion Date: January 2100 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the frequency of acute myeloid leukemia (AML) that originates in CD33+ precursors or in which uncontrolled growth is restricted to CD33+ precursors.

OUTLINE: Cryopreserved acute myeloid leukemia cell samples are separated from endothelial cell by fluorescent-activated cell sorting (FACS) and analyzed for X-chromosome inactivation patterns by cytogenetic/molecular analysis and/or Humara assay.
