摘要 目的观察老年宫颈癌患者外周血调节性T细胞(Treg细胞)、T细胞亚群(CD4^+T细胞、CD8^+T细胞)及CD4^+/CD8^+水平及其与宫颈癌临床病理特点的关系。方法选择南通市港闸区宫颈癌筛查中老年宫颈癌患者90例作为宫颈癌组,宫颈正常老年女性90例作为对照组。采用流式细胞术测定外周血Treg细胞、CD4^+T细胞、CD8^+T细胞,计算CD4^+/CD8^+比值。分析Treg细胞、CD4^+、CD8^+细胞水平与宫颈癌临床病理特征的关系。结果宫颈癌外周血Treg细胞、CD4^+T细胞、CD4^+/CD8^+高于对照组(P<0.05),CD8^+T细胞低于对照组(P<0.05)。宫颈癌外周血Treg细胞、CD4^+细胞、CD8^+细胞、CD4^+/CD8^+T与宫颈癌临床分期、分化程度、淋巴结转移有关(P<0.05),其中临床分期高、分化程度低、有淋巴结转移者外周血Treg细胞、CD4^+细胞、CD4^+/CD8^+明显高于临床分期低、分化程度高、无淋巴结转移者,CD8^+细胞明显低于临床分期低、分化程度高、无淋巴结转移者;宫颈癌外周血Treg细胞、CD4^+T细胞、CD8^+T细胞和CD4^+/CD8^+与宫颈癌年龄、宫颈癌类型、肿瘤直径、肌层浸润深度、脉管癌栓无关(P>0.05)。结论老年宫颈癌患者外周血Treg细胞和T细胞亚群水平失调,外周血Treg细胞和T细胞亚群水平与宫颈癌的临床分期、分化程度和淋巴结转移有关。
