摘要 目的探讨结肠癌患者外周血CD_4^+CD_(25)^+调节性T细胞检测的临床意义。方法采用流式细胞技术对51例结肠癌患者和30例健康体检者外周血淋巴细胞CD_4及CD_(25)进行了检测。结果(1)结肠癌组CD_4^+CD_(25)^+细胞明显高于正常对照组(P<0.05),CD_4^+CD_(25)^-细胞则显著低于正常对照组(P<0.05);(2)结肠癌组手术后患者CD_4^+CD_(25)^+、CD_4^-CD_(25)^+细胞与手术前相比显著下降(P<0.05);(3)结肠癌组淋巴结转移患者CD_4^+CD_(25)^+细胞明显高于未转移组(P<0.001)。结论CD_4^+CD_(25)^+调节性T细胞数可以反映肿瘤患者免疫系统存在抑制状态,且可能与肿瘤的免疫耐受有关,并可反映肿瘤淋巴结转移状况。
