雌、孕激素受体在甲状腺肿瘤组织中的表达

目的：检测甲状腺肿瘤组织中ER、RP的表达，并且探讨它们的表达与肿瘤浸润转移的关系。方法：应用免疫组化方法，检测100例甲状腺癌及28例甲状腺良性肿瘤中ER、PR表达。结果：甲状腺癌中ER、PR阳性表达分别为67．0％和62．0％，均与细胞分化程度、组织学类型有关，但其阳性表达与年龄、性别无关。ER、PR在无淋巴结转移组的甲状腺癌阳性率为75．4％和70．5％，显著高于有转移组53．8％和48．7％（P＜0．05）。结论：ER、PR可作为肿瘤分化及恶性程度的评价指标，并且能反映预后。

A Study on Expressions of ER and PR in Thyroid Tumors Tissue

Objecitve To observe the relationship between the expressions of the estrogen receptor (ER),progestogen receptor (PR) and tumor infiltration and metastasis in thyroid cancer.Methods By using immunohistochemical method to study the relationship between the expressions of ER and PR in 100 cases of thyroid carcinamas and 28 cases of benign thyroid lesions.Results The positive rates of ER and RP expression were 67 0% and 62 0% respectively in thyroid carcinomas,it had correlation with well differentiation and type of histology but positive expression did not relate to age and sex.The positive rates of ER and PR in the non-metastasized group were 75 4% and 70 5% respectively;significantly higher than that of the metastasized group which were 53 8% and 48 7% respectively (P<0 05).Concbusions The results suggest that the expressions of ER and PR were related to tumor differentiation and the degree of malignancy,It may indicate that the patients have a poor prognosis.
