Interestingly, difference also existed between follicular carcinoma and follicular adenoma (p = 0.028), and between follicular carcinoma and benign thyroid lesions (without Hurthle cell adenomas; p = 0.006) Having insight in ROC coordinates, the values less than 12.5 % of follicular cells expressing CD56, have sensitivity of 58 % and specificity of 92.4 % for carcinoma. Here, NCAM1 is linked to thyroid gland follicular carcinoma.
