摘要 目的观察肺癌患者外周血CD8+CD2+8、CD4+CD2+5调节性T淋巴细胞水平变化,并探讨其临床意义。方法采用流式细胞术检测86例肺癌(肺癌组)、65例肺良性肿瘤患者(良性组)及50例健康体检者(对照组)外周血中的CD8+CD2+8、CD4+CD2+5调节性T淋巴细胞。结果肺癌组术前CD8+CD2+8、CD4+CD2+5调节性T淋巴细胞分别为17.35%±3.03%、9.65%±2.01%,术后分别为12.97%±2.29%、12.23%±2.19%;良性组分别为12.22%±2.22%、14.91%±2.49%,对照组分别为11.81%±2.19%、15.22%±2.55%;肺癌组手术前后、肺癌组与良性组、对照组比较,P均<0.01;肺癌组术后与对照组比较,P均<0.05。外周血CD8+CD2+8、CD4+CD2+5调节性T淋巴细胞水平与肺癌TNM分期及淋巴结转移有关(P均<0.05),与病理类型无关(P>0.05)。结论肺癌患者外周血中CD8+CD2+8调节性T淋巴细胞水平降低、CD4+CD2+5调节性T淋巴细胞水平升高;外周血CD8+CD2+8、CD4+CD2+5调节性T淋巴细胞水平检测有助于肺癌的临床分期及疗效判定。
