摘要 目的检测乳腺癌患者外周血T淋巴细胞总数及T淋巴细胞亚群中的CD4+T细胞、CD8^+T细胞、CD45RA^+T细胞、CD45RO^+T细胞的百分率以评价患者的免疫状态。方法试验组选择女性原发性乳腺肿瘤患者40例,其中Ⅰ期乳腺癌23例,Ⅱ+Ⅲ期乳腺癌17例;以女性健康体检者30例为对照组。应用流式细胞仪,采用三色荧光免疫标记技术分别检测各组外周血T淋巴细胞亚群的数量,统计分析各组检测结果的差异性。结果试验组CD3^+T细胞、CD4^+T细胞百分率明显低于对照组(P<0.05),Ⅱ+Ⅲ期患者明显低于Ⅰ期患者(P<0.05)。与对照组比较,试验组CD45RA^+T细胞明显减少,而CD45RO^+T细胞明显增多(P<0.05);与Ⅰ期乳腺癌患者比较,Ⅱ+Ⅲ期乳腺癌患者CD45RA^+T细胞明显减少,而CD45RO^+T细胞明显增多,差异有统计学意义(P<0.05)。结论 T细胞亚群检测是评价肿瘤患者细胞免疫功能的重要指标,具有重要的临床应用价值。乳腺癌患者免疫功能与肿瘤恶变的发生、发展及临床分期有一定相关性,随着病情的进展,机体免疫功能呈现下降趋势。
