ABSTRACT
Objective To explore the expressions of ER,PR and CerbB-2 in human papillary thyroid carcinoma,and their correlation with the clinical features.Methods The expressions of ER,PR and CerbB-2 were detected by immunohistochemistry in 89 papillary thyroid carcinoma samples and 13 nodular goiter samples.Results In papillary thyroid carcinoma samples,ER,PR and CerbB-2 were detected for 50.56 ％(45/89),43.82 ％ (39/89),24.72 ％ (22/89),respectively.In nodular goiter,ER,PR and CerbB-2 were detected for 15.38 ％ (2/13),7.69 ％ (1/13),0,respectively,there were significant differences between the two groups (x2 =5.649,P=0.017,x2 =6.211,P=0.013,x2 =4.097,P=0.043).The positive rates of PR were 56.26 ％(26/46) in without lymph node metastasis,compared with those lymph node metastasis 30.2 3％ (13/43) were significantly higher,the difference was statistically significant (x2 =6.239,P =0.012).Conclusion The expressions of ER,PR and CerbB-2 are significant higher in papillary thyroid carcinoma.The detection of ER,PR and CerbB-2 might be helpful for early diagnosis and prognosis of papillary thyroid carcinoma.
ABSTRACT
Objective To investigate the expression of ER and PR in hyperplasia of mammary glands and breast cancer. Methods The expression of ER and PR in 68 hyperplasia of mammary glands cases and 168 breast cancer cases were quantified by immunohistochemical method. Results The expression of ER in breast cancer(30%) was significantly higher than that in hyperplasia of mammary glands(10 %)(P ＜0.05) and there was no significant difference in PR between them. The expression of ER in postmenopausal breast cancer was significantly higher than that in postmenopausal hyperplasia of mammary glands (P ＜0.05) and there was no significant difference in ER between two premenopausal groups. The expression of PR in invasive lobular carcinoma was significantly higher than that in invasive ductal carcinoma and other types (P=0.005).Conclusion The expression of ER and PR may identify the characteristics of patholobiology in breast disease.
