Abstract:
Purpose:To investigate the expression and clinical significance of estrogen receptor and Cyclin D1 in the differentiated thyrord carcinoma. Methods:We investigated the expression of ER and Cyclin D1 in thyroid normal tissue, thyroid adenoma and DTC by SP immunohistochemical technique. We have collected 89 specimens from surgical resections, and all the sections were formalin-fixed and paraffin-embedded, each has detailed clinical data, two pathologists classified the histopathologic types. DTC 43 cases (papillary thyroid carcinoma, 39 cases, follicular thyroid carcinoma, 4 cases); thyroid follicular adenoma 30 cases, and 16 cases of normal thyroid tissues taken from around the thyroid adenoma. Results:The positive rates of ER and CyclinD1 in the DTC were 53.5%(23/43), 65.1%(28/43) respectively; the positive rates of ER and CyclinD1 in the thyroid adenoma were 26.7%(8/30), 36.7%(11/30) respectively; the positive rates of ER in normal thyroid tissues were 12.5%(2/16), while CyclinD1 were negative. The ER expression in DTC was significantly higher than that in the thyroid adenoma and the normal thyroid tissues(P
