摘要 目的 分析乳腺导管原位癌(DCIS)发展至浸润性导管癌(IDC)的过程中,雌激素受体(ER)、孕激素受体(PR)、c-erb B2基因(HER-2)和增生细胞核抗原(Ki-67)表达水平的变化,以及它们和临床病理指标的联系。方法 选取了220例老年乳腺癌术后标本,包括42例DCIS和178例IDC。所有标本均通过免疫组化测定ER、PR、HER-2和Ki-67的表达。用线性回归分析ER、PR、HER-2、Ki-67与临床病理的相关性。结果 与DCIS相比,IDC中ER和PR的表达降低(分别为38.1%vs 22.5%,χ~2=4.371,P=0.037;28.6%vs 14.0%,χ~2=5.126,P=0.024)。但是在IDC中HER-2的表达增加(11.9%vs 26.4%,χ~2=3.958,P=0.047)。Ki-67的表达在DCIS和IDC中并没有显著差异(14.3%vs 15.7%,χ~2=0.054,P=0.816)。结论 ER、PR和HER-2的表达变化与老年乳腺癌的进展有关联。
