摘要 目的观察非小细胞肺癌中CD163+巨噬细胞表达水平变化。方法收集经病理证实的非小细胞肺癌组织47例,采用免疫组化法检测癌巢、癌内间质、癌与正常肺交界区的CD163+巨噬细胞。结果非小细胞肺癌组织中癌内间质及癌与正常交界区CD163+巨噬细胞高表达患者的比例为72%、65%,均高于癌巢中的43%,P均<0.05。癌与正常交界区CD163+巨噬细胞高表达与非小细胞肺癌临床分期及淋巴结受累有关,P均<0.05;交界区CD163+巨噬细胞高表达者平均生存时间(767 d)明显少于低表达者(1 385 d),P<0.05;Cox风险回归多因素分析显示,交界区CD163+巨噬细胞表达、临床分期是非小细胞肺癌患者预后的独立预测指标(HR 4.22,95%CI 1.55~11.53,P<0.05)。结论非小细胞肺癌癌巢组织、癌内间质及癌正常交界区均存在CD+巨噬细胞表达。
