应用流式细胞仪检测３９例大肠癌患者手术前后Ｔ细胞表面６种细胞表型，发现随着Ｄｕｋｅｓ分期的增高，术前ＣＤ３、ＣＤ４、ＣＤ４／ＣＤ８、ＣＤ１６、ＣＤ６９及ＣＤ３＋／ＨＬＡ－ＤＲ＋逐渐下降，ＣＤ８逐渐增高（Ｐ＜０．０５）；Ａ期大肠癌患者机体免疫功能活跃，术前ＣＤ３、ＣＤ４高于对照组（Ｐ＜０．０５），ＣＤ８、ＣＤ４／ＣＤ８、ＣＤ１６、ＣＤ３＋／ＨＬＡ－ＤＲ＋与对照组相同；根治及姑息性切除术后，ＣＤ８降低，ＣＤ３、ＣＤ４、ＣＤ４／ＣＤ８、ＣＤ１６、ＣＤ６９、ＣＤ３＋／ＨＬＡ－ＤＲ＋升高（Ｐ＜０．０５）；肿瘤未切组术后ＣＤ３、ＣＤ１６、ＣＤ４／ＣＤ８进一步下降（Ｐ＜０．０５）。提示大肠癌患者术前免疫状态与疾病的程度呈负相关，切除肿瘤有益于改善患者细胞免疫功能。
Flow cytometry was used to detect the phenotypes of 6 kinds of cells on the surface of T cells before and after operation in 39 patients with colorectal cancer. It was found that the preoperative CD3, CD4, CD4 / CD8, CD16, CD69 and CD3 + / HLA-DR + CD8, CD4 / CD8, CD16 and CD3 + / CD8 were higher in the patients with stage A colorectal cancer than those in the control group (P <0.05) The levels of CD8, CD4, CD4 / CD8, CD16, CD69, CD3 + / HLA-DR + were significantly increased in the control group after the radical and palliative resection (P <0.05) Postoperative CD3, CD16, CD4 / CD8 decreased further (P <0.05). Prompted that the preoperative immune status of patients with colorectal cancer and the degree of disease was negatively correlated, resection of the tumor is beneficial to improve cellular immune function.
