Primary Outcome Measures:
  • Diagnostic accuracy of biomarkers by mRNA expression analysis [ Designated as safety issue: No ]
  • Correlate levels of gene expression with the aggressiveness of differentiated thyroid cancer in FNA biopsy samples [ Designated as safety issue: No ]

Estimated Enrollment: 400
Study Start Date: July 2005
Estimated Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Detailed Description:


  • Evaluate the diagnostic accuracy of biomarkers and mRNA expression analysis using fine-needle aspiration (FNA) biopsy samples from patients with thyroid nodules.
  • Correlate the level of gene expression with the aggressiveness of differentiated thyroid cancer in FNA biopsy samples.

OUTLINE: Patients undergo fine-needle aspiration (FNA) biopsy as part of routine care. Additional thyroid tissue is collected during the biopsy for gene expression analysis. Patients who have already had a biopsy undergo FNA biopsy during thyroidectomy.

Tissue samples will be examined for gene expression by reverse transcriptase-polymerase chain reaction (PCR), real-time quantitative PCR, and immunohistochemistry.

PROJECTED ACCRUAL: A total of 400 patients will be accrued for this study.
