摘要 目的 分析Ki67指数在各分子分型乳腺癌组织中的表达水平及临床意义。方法 回顾性分析该院2013年1月至2013年12月收治的621例乳腺浸润性导管癌患者的临床病理资料,通过免疫组织化学(IHc)方法测定雌激素受体(ER)、孕激素受体(PR)、表皮生长因子受体-2(HER-2)及Ki67的表达情况以区分不同的分子亚型。结果 621例女性乳腺浸润性导管癌患者的Ki67指数为0%~95%,平均为40.83%。以14%为界,将乳腺癌患者的Ki67指数分为两组,其中,Ki67指数小于或等于14%乳腺癌患者109例(17.6 oA),Ki67〉14Voo乳腺癌患者512例(82.4%)。患者年龄、肿瘤大小、淋巴结转移状态、肿瘤病理分期与Ki67指数均无关(均P〉0.05)。患者组织学分级、ER状态、PR状态、HER-2状态与Ki67指数均有关(均P〈0.01)。Luminal A型、Luminal B型、HER_2过表达型、三阴性患者的Ki67指数分别为10.00%、40.00%、40.00%、70.00%,其中,其他三型的Ki67指数均明显高于Luminal A型(均P〈O.01),Luminal B型、HER-2过表达型、三阴性三者之间的Ki67指数比较差异有统计学意义(P〈0.05)。三阴性乳腺癌患者的Ki67指数(70.00%)显著高于非三阴性乳腺癌患者(30.00%)。结论 Ki67与乳腺癌的临床病理特征有一定的相关性,与ER、PR、HER-2同时检测可能对判断乳腺癌预后有重要意义。
