摘要 目的探讨乳腺癌患者外周血中T淋巴细胞亚群及调节性T细胞的变化和临床意义。方法采用流式细胞技术检测30例乳腺癌患者外周血中T淋巴细胞亚群及调节性T细胞的变化,并与健康对照组进行比较。结果乳腺癌患者外周血CD4+CD25+及CD4+CD25+high调节性T细胞占CD3+CD4+T细胞的比率为(15.52±1.54)%及(3.49±0.54)%,高于健康对照组(6.11±0.72)%及(1.42±0.61)%,差异有统计学意义(P<0.05);乳腺癌患者CD3+T淋巴细胞比率为(50.98±6.79)%、CD4+Th细胞比率为(28.37±7.58)%和Th/Ts比值为(1.05±0.38),显著低于健康对照组(67.55±5.98)%、(40.12±5.27)%和(1.59±0.65),差异有统计学意义(均P<0.05),而CD8+Ts细胞比率为(30.05±7.79)%,与健康对照组(29.97±7.14)%比较,差异无统计学意义(P>0.05)。结论乳腺癌患者外周血调节性T细胞水平升高,T淋巴细胞及Th细胞降低可能是乳腺癌患者细胞免疫功能受损的重要原因之一。
