Abstract:
Objective To explore the expression and significance of Kiss-1, Ki-67 and VEGF-C in papillary thyroid carcinoma(PTC) and thyroid follicular adenoma (FA).Methods Forty-four cases of PTC and twelve cases of FA paraffin-embedded tissues were used .Immunohistochemical staining and microscopic image analysis technique were used to analyze the expression of Kiss-1, Ki-67 and VEGF-C.Results The integrated optical density (IOD) of Kiss-1, and VEGF-C in the PTC groups was 475.56 ±126.02 and 805.29 ±226.05,respectively.The proliferation index of Ki-67 protein was (3.36 ±1.11) %and the difference between the PTC and FA groups was statistically significant (P<0.05).The IOD of the above two indices was 408.12 ±124.05 and 912.63 ±108.12 in the PTC with lymph node metastasis group , respectively, while the proliferation index of Ki -67 protein was (3.93 ±0.92) % and the difference vs the group without lymph node metastasis was significant ( P <0.05 ) .In the PTC with capsular infiltration group the IOD of above two was 425.58 ±87.38 and 891.37 ±149.36, the proliferation index of Ki -67 protein was (3.79 ±1.09) %and the difference with PTC group without capsular infiltrtion was statistically significant (P<0.05).Linear correlation analysis showed that Ki-67 and VEGF-C were with positively correlated in PTC and FA tissues (P<0.05),while Kiss-1 and Ki-67, VEGF-C were with negatively correlated in PTC and FA tissues (P<0.05).Conclusion Kiss-1, Ki-67 and VEGF-C can facilitate the differential diagnosis of PTC and FA , serving as prognostic indicators in patients with PTC .
