Abstract:
Background and purpose: Thyroid carcinoma cells spread mainly through lymph node metastasis, and lymphangiogenesis plays an important role during the lymph node metastasis, but it is not very clear to understand the formation mechanism. This study was to investigate the correlative expressions of HPSE, VEGF-C, D2-40 and lymphangiogenesis in thyroid carcinoma. Methods: Immunohistochemistry SP method was used to detect the expressions of HPSE, VEGF-C and D2-40 in 77 patients with thyroid carcinoma including papillary thyroid carcinoma (PTC), follicular thyroid carcinoma (FTC),medullary thyroid carcinoma (MTC), 32 of them with lymph node metastasis was enrolled into the study, D2-40 stained the lymphatic vessels, and lymphatic vessel density (LVD) was scanned under the light-microscope, and the correlation among the above indexes in different thyroid carcinoma types were analyzed respectively. Results: The expressions of HPSE, VEGF-C and D2-40 were observed to have a different degree in thyroid carcinoma, and the highest expression of the protein could be seen in the patients with papillary carcinoma (P<0.05),The expression ratios of HPSE,VEGF-C and D2-40 in different carcinoma types were 54.9%, 68.6%, 12.8±5.7 for PTC, 37.5%, 50%, 8.6±1.7 for FTC, 20% and 20%, 4.9±0.8 for MTC, respectively. There were significant different expressions of HPSE, VEGF-C and D2-40 between the patients with lymph node-positive group and node-negative group (P=0.014, P=0.048, respectively). In addition, the expressions of them were positively correlated (P<0.001, r=0.616). Conclusion: HPSE, VEGF-C and D2-40 have a close relationship with lymph node metastasis, HPSE and VEGF-C are related to the lymphangiogenesis.
