Objective: To investigate the expressions of D2-40, CK19, galectin-3, VEGF, and EGFR in papillary thyroid carcinoma and their clinical significances. Methods: The expressions of D2-40, CK19, galectin-3, VEGF, and EGFR in 38 cases of papillary thyroid carcinoma and 12 cases of thyroid papillary hyperplasia were detected by immunohistochemical staining. Results: The positive expression rates of D2-40, CK19, Galectin-3, VEGF and EGFR in patients with papillary thyroid carcinoma were all significantly higher than those in patients with thyroid papillary hyperplasia (all P< 0.05). The expressions of D2-40, VEGF, and EGFR in papillary thyroid carcinoma with lymph node metastasis were significantly higher than those without lymph node metastasis (P< 0.05). The expressions of GK19 and galectin-3 showed no significant differences between the papillary thyroid carcinomas with and without lymph node metastasis (P> 0.05). Conclusions: The detection of D2-40, CK19, galectin-3, VEGF, and EGFR is helpful for the diagnosis and differential diagnosis of papillary thyroid carcinoma and thyroid papillary hyperplasia.
