Expression of the selected adhesive molecules (cadherin E, CD44, LGAL3 and CA50) in papillary thyroid carcinoma
open access
Abstract
Material and methods: 47 papillary thyroid carcinoma cases and 11 nonmalignant goiter cases were analyzed by immunohistochemistry.
Results: Galectin-3 (LGAL3) was a sensitive and specific marker, present in 91% of analyzed tumors and only in 5% of tumor margin. The presence of CA50 was 86% and 3% respectively with only 3% positive non-malignant cases. Cadherin E expression was noted in 91% of primary tumors, in 84% of the surrounding tissue and in 63% of non-malignant goiter. CD44 (DF1485) was observed in 89% of primary tumors and 48% of surrounding tissue; the reaction with BBA10 was more characteristic for metastases.
Conclusions: Our study confirms the high diagnostic value of galectin-3 in papillary thyroid carcinoma and reveals the similar efficiency of CA50. CD44 (DF1485) expression in primary tumor is more intensive than in surrounding tissue, but the diagnostical inportance is not high because it is often observed in benign lesions. Using of BBA10 is more sensitive, but less specific. High expression of cadherin E in benign lesions impairs its diagnostical application in papillary thyroid cancer.
