摘要 目的:研究T淋巴细胞和肿瘤相关巨噬细胞(TAMs)在乳腺病变组织中的分布和意义。方法:收集石蜡包埋的乳腺癌组织119例及乳腺良性病变组织30例,采用免疫组化法检测CD3和CD68标记T淋巴细胞和TAMs,定量分析组织中浸润的阳性细胞数。结果:T淋巴细胞的数量在乳腺癌组织中为(79.0±20.5)个/HPF,明显高于其在乳腺良性病变组织中的(9.8±3.8)个/HPF(P<0.01)。TAMs数量在乳腺癌组织中为(93.0±33.3)个/HPF,乳腺良性病变组织中为(20.9±6.4)个/HPF,两者差异有统计学意义(P<0.01)。ER和PR阳性、肿瘤直径≤2 cm及无淋巴结转移的乳腺癌组织中浸润的T淋巴细胞的数明显多于ER和PR阴性、肿瘤直径>2 cm及有淋巴结转移者(P<0.05)。TAMs与乳腺癌临床病理特征无明显相关,但在淋巴结转移病例有减少趋势。结论:乳腺癌组织中浸润的T细胞和巨噬细胞数量高于乳腺良性病变组织,T细胞和巨噬细胞数量可能是反映机体抗肿瘤免疫状态的指标之一。
