摘要
目的探讨乳腺癌原发灶和淋巴结转移灶中雌激素受体(ER)、孕激素受体(PR)表达及其与肿瘤分期、病理类型的关系。方法采用免疫组化SP法,检测36例乳腺癌术后患者原发灶和淋巴结转移灶中的ER、PR表达。结果乳腺癌原发灶中的ER阳性率69.5%、PR阳性率55.6%,淋巴结转移灶中分别为63.9%、44.4%;原发灶和淋巴结转移灶中的ER、PR表达呈正相关(P均<0.01),与肿瘤分期、病理类型无明显相关性(P均<0.01)。结论判断乳腺癌患者的预后应综合考虑其原发灶和转移灶的生物学特性。
Objective To investigate the protein expressions of estrogen receptor （ ER ）, progesterone receptor（PR） in breast cancer and their lymph-node metastatic tumor and the correlation between ER, PR and tumor staging, pathological type. Methods High sensitive S-P immunohistochemical method was used to detect the protein expressions of ER, PR in primary lesion or metastasis in 36 breast cancers. Results ER positive rate in primary lesion was 69.5%, PR positive rate in primary lesion was 55.6%. ER and PR positive rate in metastasis was separately 63.9% , 44.4%. The expressions of ER were positively associated with PR in primary lesion and lymphatic metastasis（ P 〈 0.01 ）, and were not correlated with tumor staging and pathological type. Conclusion Biological characteristic in primary lesion and metastasis of breast cancers should be synthetically considered to predict the prognosis of patients.
