Array-based genome-wide transcriptome analysis of Minimally invasive follicular thyroid carcinomas

Minimally invasive follicular thyroid carcinoma (MI-FTC) is characterized by limited capsular and/or vascular invasion with good long-term outcomes. However, some cases of MI-FTC show a poor prognosis because of severe distant metastasis. Nonetheless, no method has been established for predicting the prognosis of MI-FTC. This study was conducted to identify novel prognostic factors for metastatic MI-FTC by use of the formalin-fixed paraffin-embedded (FFPE) specimens of this carcinoma. The tumorous and non-tumorous regions of FFPE thyroid specimens from 3 MI-FTC patients.
