RESUMO
Xu XP,Xiao N);Department ofGeneral Surgery,Pingxiang People's Hospital,Pingxiang,Jiangxi 337000,China(Rong J) Objective To study the expression of vascular endothelial growth factor(VEGF),S100A4 and survivin in thyroid carcinoma and their clinical significance.Methods The expression of VEGF,S100A4 and survivin in normal thyroid tissues from 28 people and thyroid cancer tissues obtained from 73 patients were detect by immuno-histochemistry method.Results The positive rates of VEGF,S100A4 and survivin in thyroid cancer were 84.93%, 86.30% and 79.45%,which in the normal thyroid tissues were 3.57%,7.14% and 14.29%,respectively.There were significant differences between every two groups,thyroid cancer and the normal thyroid tissues,statistically(χ2 =57.08,55.28,36.26,all P =0.000).VEGF,S100A4 and survivin in the positive expression of capsular infiltration carcinoma group were 97.37%,97.74%,97.74%,which in lymph node metastasis positive group cancer rates were 97.30%,94.60%,97.30% were significantly increased compared with no capsular infiltration group (71.43%, 77.14%,62.86%,respectively)and lymph node metastasis group(72.22%,77.78%,61.11%),the differences were statistically significant(χ2 =8.96,4.37,14.63,9.58,4.77,11.34,all P <0.05);the positive expression rate of three with thyroid cancer histological grade increased.Conclusion VEGF,S100A4 and survivin are closely related to the aggressive and metastatic character of thyroid cancer.A combination of VEGF,S100A4 and survivin may be of grate significance for predicting high aggressive and metastatic character in thyroid carcinoma.
