70岁及以上乳腺癌患者雌孕激素受体和表皮生长因子受体-2表达与病理的关系

目的 探讨70岁及以上乳腺癌患者雌激素受体(ER)、孕激素受体(PR)、人类表皮生长因子受体2(Her-2)的表达情况及其与临床病理的关系.方法 回顾性分析124例70岁及以上原发性乳腺癌患者的临床和病理资料,采用免疫组化二步法测定乳腺癌组织中ER、PR、Her-2的表达,并对ER、PR、Her-2与病理类型、肿瘤大小、腋窝淋巴结转移状况和病理分期的相关性进行分析.结果 124例患者乳腺癌组织中ER、PR的表达阳性率分别为75.0%(93/124)、71.0%(88/124),Her-2表达+++的阳性率11.3%(14/124),Her-2表达++的阳性率24.2%(30/124).ER、PR的表达与乳腺癌的病理类型、肿瘤大小、淋巴结转移、病理分期均无相关性(P＞0.05),Her-2与乳腺癌的病理类型无相关性(P＞0.05),与肿瘤大小、淋巴结转移、病理分期均呈正相关(均P＜0.05).结论 70岁以上乳腺癌组织中ER、PR表达阳性率高,其与临床病理预后指标不相关;Her-2过度表达与临床病理预后指标相关.

Expressions of estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 and relationships of these expressions with clinical pathology in breast cancer patients aged 70 years old and over

Objective To investigate the expressions of estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER-2) and relationships of these expressions with the clinicopathology in breast cancer patients aged 70 years old and over. Methods The expressions of ER, PR and HER-2 were detected by immunohistochemical staining from 124 elderly breast cancer patients, and the relationships of these expressions with pathological classification, tumor size, lymph node metastasis and TNM stage were analyzed. Results Among 124 patients, the positive expression rate of ER and PR was 75.0% (93/124) and 71.0% (88/124),respectively. They were not associated with pathological classification, tumor size, lymph node metastasis or TNM stage (all P＞0. 05). The positive expression rate of Her-2(+++) and Her-2 (++) was 11.3% (14/124) and 24.2% (30/124), respectively. And the expression of Her-2 was significantly associated with tumor size, lymph node metastasis and TNM stage (P＜0. 05) but not with pathological classification (P＞0. 05). Conclusions The positive expressions of ER and PR are not correlated with the clinicopathology in elderly breast cancer patients. Her-2 overexpression is positively associated with tumor size, lymph node metastasis and TNM stage.
