Popis: | Metastatic dissemination of papillary thyroid cancer has been reported to be strongly associated with expression of platelet-derived growth factor (PDGFR) α and altered TTF1 function. However, the status of PDGF ligands in papillary thyroid cancer and the potential role of these ligands in metastatic disease are obscure. We assessed the prevalence of PDGF ligands in benign and malignant thyroid tumors to determine if ligand upregulation is associated with α-isoform (PDGF-AA or PDGF-BB) or the β-isoform (PDGF-BB or PDGF-DD) of PDGFR in individual tumors. The immunohistochemical expression of PDGFRα, PDGF-AA, PDGF-BB, and PDGF-DD was surveyed in follicular adenomas (n=55), papillary thyroid carcinomas (103 with and 59 without nodal metastases), and lymph node metastasis (n=12). There is an augmented tendency for PDGF-AA expression in node-positive papillary thyroid cancer metastases (P |
