摘要 目的观察雄激素受体(AR)及Ki-67在雌激素受体(ER)(-)/人表皮生长因子受体2(HER2)(+)的乳腺癌组织中的表达及AR与临床病理特征、Ki-67强度的相关性。方法收集该科2007年1月至2015年12月经病理学确诊为乳腺癌的62例患者的组织标本,采用免疫组织化学En Vision两步法检测ER(-)/HER2(+)乳腺癌组织中AR和Ki-67的表达,统计分析AR与临床病理特征、Ki-67表达强度的相关性。结果 AR表达率为69.57%,Ki-67表达率为5%~8%。AR表达与肿瘤组织学分级、Ki-67表达强度及淋巴脉管侵犯相关(P〈0.01或0.05),且与Ki-67高强度表达呈负相关(P〈0.05),而与年龄、肿瘤大小、绝经与否、淋巴结转移及临床分期无明显相关性(P〉0.05)。结论 ER(-)/HER2(+)乳腺癌组织中AR表达率较高,与肿瘤分级、Ki-67高强度及淋巴脉管侵犯相关,提示AR高表达者预后较好。
