【摘要】：目的:研究胃癌患者外周血T淋巴细胞亚群变化的临床意义。方法:选取2015年10月至2016年5月北京世纪坛医院肿瘤内科收治的67例胃癌患者,抽取外周血,采用流式细胞术检测T细胞及其亚群,同时抽取外周血检测肿瘤标记物CEA、CA199,对结果进行分析比较,并对患者进行随访。结果:67例胃癌患者中,Ⅲ期患者Tc(CD8+CD28+)均值为12.3±5.1,Ⅳ期患者Tc(CD8+CD28+)均值为9.9±4.6,两者比较差异具有统计学意义(P=0.043);CEA升高的患者Tc(CD8+CD28+)均值为9.3±3.6,而CA199未升高的患者Tc(CD8+CD28+)均值为12.1±5.6(P=0.025)。CA199升高的患者Tc(CD8+CD28+)均值为9.3±4.2,而CEA未升高的患者Tc(CD8+CD28+)均值为12.1±5.3(P=0.029),Tc(CD8+CD28+)下降的患者较未下降的患者的总生存时间(overall survival,OS)降低(8.1个月vs.15.1个月,P=0.008)。结论:胃癌患者随着TNM分期的提高,其机体的细胞免疫功能呈现逐渐下降的趋势;CEA、CA199升高的患者Tc(CD8+CD28+)降低,二者呈负相关;Tc(CD8+CD28+)降低,患者的OS缩短。
[Abstract]:Objective: to study the clinical significance of T lymphocyte subsets in peripheral blood of patients with gastric cancer. Methods: from October 2015 to May 2016, 67 patients with gastric cancer were selected from Department of Oncology, Beijing Shijitan Hospital. Peripheral blood was extracted, T cells and their subsets were detected by flow cytometry, and tumor marker CEA,CA199, was detected by peripheral blood. The results were analyzed and compared, and the patients were followed up. Results: in 67 patients with gastric cancer, the mean value of Tc (CD8 CD28) was 12.3 卤5.1 in stage 鈪，
