摘要 目的通过检测乳腺癌中树突状细胞(dendritic ce lls,DC)和T细胞的分布状况和浸润密度,分析其与临床病理资料的关系,探讨DC在乳腺癌局部免疫中的作用。方法应用免疫组化方法检测67例乳腺癌中S100+DC、HLA-DR+DC、CD 1a+DC(DC三参数)、CD 45RO+T细胞的浸润密度和c-erbB-2表达情况。结果S100+DC和HLA-DR+DC浸润密度在癌巢内均显著低于癌巢周围(P值均<0.001),而CD 1a+DC浸润密度在癌巢内显著高于癌巢周围(P=0.001);S100+DC、CD 1a+DC和CD 45RO+T细胞浸润密度在低分化病例均显著高于高、中分化病例(P值均<0.05);S100+DC浸润密度与组织学分级呈明显正相关(rs=0.286,P=0.042);CD 1a+DC阳性表达率在肿瘤≤2 cm的病例显著高于肿瘤>2 cm的病例(P<0.05);DC三参数及CD 45RO+T细胞阳性表达率和浸润密度与有无腋淋巴结转移、临床分期及c-erbB-2表达情况均无关。结论DC三参数在乳腺癌中分布部位不同,可标记不同成熟状态的DC,综合检测DC三参数可更全面地反映乳腺癌局部免疫状态。
