Abstract:
:The identification of high-risk patients with thyroid cancer and the preoperative differentiation between follicular adenoma and carcinoma remain clinically challenging. Our study was conducted to analyze whether the quantification of matrix metalloproteinases (MMPs) and urokinase-type plasminogen activator receptor (u-PAR) and transcription factor binding to the u-PAR promoter improve prognostic predictability and differential diagnosis of thyroid tumors. Tumor/normal tissue was collected from 69 prospectively followed patients with thyroid carcinomas (papillary, medullary, follicular and anaplastic, PTC, MTC, FTC and ATC) or follicular adenomas. U-PAR, MMP-1, MMP-7 and MMP-9 amounts were determined by ELISA, and transcription factor binding was determined by electrophoretic mobility shift assay. Binding of transcription factors to the u-PAR promoter was observed, but not associated with u-PAR expression. Carcinomas except MTC expressed significantly more u-PAR/MMPs than adenomas/normal tissues, this being associated with advanced pT- or M-stages. MMP-1 and MMP-9 were significantly higher in follicular carcinomas than in adenomas. In carcinomas, high u-PAR-gene expression correlated significantly with high MMP-9, the latter being associated with MMP-7 in normal tissues. Poor survival in differentiated tumors was associated in trend (p = 0.07); poor survival of all patients (p = 0.043) and especially of patients with carcinomas of follicular origin (including ATC), but not medullary carcinomas, were significantly associated with high u-PAR-protein (p = 0.015). Quantification of u-PAR is of prognostic relevance in thyroid carcinomas of non-c-cell origin, and u-PAR in part may be regulated nontranscriptionally in thyroid cancers. This is the first study to suggest MMP-1/-9 as significant differentiation markers between follicular adenoma and follicular carcinoma.
