Abstract

目的 探讨雌激素受体(ER)、孕激素受体(PR)、生长因子受体(HER-2)、P-糖蛋白(P-gp)和谷胱甘肽-S-转移酶(GST-π)在乳腺癌中的表达与临床意义.方法 应用免疫组织化学技术,检测85例乳腺癌患者中ER、PR、HER-2和P-gp、GST-π多药耐药的表达.结果 85例乳腺癌患者中ER阳性率为52%,PR阳性率为51%,HER-2阴性率为54%,P-gp检测为(-)~(+)占85%,GST-π检测为(-)~(+)占69%,与乳腺癌临床化疗有相关性.结论 ER、PR、HER-2、P-gp联合表达与乳腺癌化疗密切相关,检测ER、PR、HER-2、P-gp和GST-π对乳腺癌化疗方案的制定具有重要的意义。
