Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Correlations between levels of pY-Stat3 and levels of upstream cytokine receptors [ Designated as safety issue: No ]
  • Association of constitutive and/or increased pY-Stat3 and c-kit genotype [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: September 2009
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Detailed Description:


  • Determine the frequency of ligand-independent phosphorylation of Stat3 in a small cohort of samples from pediatric patients with acute myeloid leukemia including, but not limited to, samples known to express mutated c-kit.
  • Measure the level of Stat3 phosphorylation in these samples after stimulation of three key cytokine receptors expressed on hematopoietic cells IL-6R, G-CSFR, and c-kit.

OUTLINE: Cryopreserved samples are analyzed for levels of various components of the Stat3 pathway via western blotting.
