Abstract:
Objectives To investigate the expression and differential diagnosis value of Galectin-3 and Cyclin D1 in benign and malignant thyroid mass.Methods The expression of Galectin-3 and Cyclin D1 protein in 31 cases of nodular goiter(group A),65 cases of papillary thyroid carcinoma(PTC,group B) and 10 cases of normal thyroid tissues(group C,the control group)was detected by SP immunohistochemical method.The clinical data were analyzed.Results The expression level of Galectin-3 in group B was 83.03％ (54/65),significantly higher than that in group A(19.35％,6/31) and group C(0％).The difference of group A and group B in terms of the expression level of Galectin-3 protein had statistical significance(x2 =36.360,P ＜0.05).The expression level of Cyclin D1 protein in group B was 72.30％ (47/65),significantly higher than that in group A(12.90％,4/31)and group C(0％).The difference of group A and group B in terms of the expression level of Cyclin D1 protein had statistical significance(x2 =29.740,P ＜ 0.05).The combination detection of the positive expression of Galectin-3 and Cyclin D1 in benign and malignant thyroid mass showed that the difference between group A and group B had statistical significance(P ＜ 0.01).The expression of Galectin-3 and Cyclin D1 was positively correlated in group B(R =0.509,P ＜0.05).The positive expression rate of Cyclin D1 protein was 90％ (18/20) and 64.44％ (29/45)respectively in PTC patients with lymph node metastasis and without lymph node metastasis.The difference had statistical significance (P ＜ 0.05).Conclusions The expression of Galectin-3 and Cyclin D1 is positively correlated in PTC and the expression of the 2 proteins in PTC is higher than that in nodular goiter and normal thyroid tissues,indicating that the 2 proteins can be used as valuable markers for patients with thyroid carcinoma.Combined detection of Cyclin D1 and Galectin-3 protein in thyroid tissues is useful for the diagnosis of thyroid cancer.
