Abstract
Background and Objectives
Follicular tumors can present a difficult diagnostic challenge for cytological evaluation and ultrasound findings. Therefore, new methods which could help distinguish follicular adenoma from follicular carcinoma simply and accurately are greatly desired. This study investigated the usefulness of immnunohistochemical expression of CXC chemokine receptor 4 (CXCR4) and galectin-3 as marker of differentiated thyroid carcinomas.
Materials and Methods
Expression of CXCR4 and galectin-3 were examined immunohistochemically in the 60 paraffin embedded tissues which were already diagnosed as follicular adenoma (n=20), follicullar carcinoma (n=20), and papillary carcinoma (n=20) of thyroid.
Results
Galatin-3 was expressed significantly high in follicular carcinoma than follicular adenoma (p=0.022). CXCR4 was also expressed significantly high in follicular carcinoma than follicular adenoma (p=0.027). The sensitivity of CXCR4 and galectin-3 was 70% and 80% and specificity, 65% and 60% for differential diagnosis of follicular tumors.
