结直肠癌患者可溶性CD44v6的检测

sCD44v6 in the diagnosis of colorectum cancer

目的 探讨检测血清可溶性细胞表面分化抗原 (sCD) 4 4v6在结直肠癌诊断中的价值。方法 以酶联免疫吸附测定 (ELISA)法检测 81例结直肠癌患者术前及术后第 1、5、10天共 4个时间点sCD44v6的变化 ,并结合临床资料进行分析。结果 结直肠癌组sCD44v6的水平 [(2 0 0 .5±31.1) μg/L]明显高于正常对照组 [(4 5 .6± 9.5 ) μg/L]和结肠炎组 [(4 8.3± 7.6 ) μg/L],差异均有显著意义 (P均 <0 .0 5 ) ;结直肠癌伴转移组sCD44v6水平 [(2 80 .1± 2 6 .9) μg/L],明显高于未转移组[(16 0 .9± 34 .4) μg/L],差异有显著意义 (P <0 .0 5 ) ;术后第 1、5、10天sCD44v6水平逐渐下降 ,至第 10天降至正常。结论 sCD44v6水平与结直肠癌及其转移有明显关联 ,其可作为结直肠癌的诊断、预后诊断的参考指标 。

Objective To explore the role of sCD44v6 in the diagnosis of colorectum cancer. Methods ELISA was used to detect the concentration of sCD44v6 of 81 patients after or before surgery.Results The level of sCD44v6 in the group of colorectum cancer was 200.5±31.1 ng/ml, which was higher than that of normal controls (45.6±9.5ng/ml) and that of patients with coloritis (48.3±7.6ng/ml). The concentration of sCD44v6 in the group of colorectum cancer with metastasis(280.1±26.9ng/ml) was higher than that of the group without metastasis(160.9±34.4ng/ml). The level of sCD44v6 was related to tumor burden.Conclusions The level of sCD44v6 is closely related to colorectal cancer and its metastasis. It would be useful in the diagnosis, prognosis, and forcasting of metastasis.
