肺癌患者血清IL-6、IL-8及TNF-α的表达及临床意义

摘要

目的 研究肺癌患者血清白介素-6(IL-6)、IL-8及肿瘤坏死因子-α(TNF-α)的表达,并探讨其在肺癌发病中的作用.方法 用ELISA法检测45例肺癌患者血清IL-6、IL-8及TNF-α的水平,并与30例健康人做比较.结果 肺癌患者血清中IL-6、IL-8及TNF-α的表达水平明显高于健康对照组(P＜0.01),肺癌患者血清中IL-6、IL-8及TNF-α的表达水平随着临床分期的进展而升高.结论 IL-6、IL-8及TNF-α参与了肺癌的发生、发展,检测其血清含量对了解肺癌患者体内免疫状态和预后判断有重要意义.%Objective To investigate the clinical significance of detection of serum levels of interleukin-6 (IL-6) , interleukin-8 (IL-8) , tumor necrosis factor-a( TNF-a) in patients with lung cancer. Methods The serum concentrations of IL-6, IL-8 and TNF-a from 45 patients with lung cancer and 30 healthy subjects were detected by ELISA. Results The serum levels of IL-6, IL-8 and TNF-α in patients with lung cancer were significantly higher than those of healthy subjects ( P <0. 01) . The serum levels of IL-6, IL-8 and TNF-a in patients with lung cancer were closely correlated with tumor' s TNM stages. Conclusion The expressions of IL-6, IL-8 and TNF-a are increased in patients with lung cancer. IL-6, IL-8 and TNF-a are involved in the development and metastasis of lung cancer. The detection of the serum levels of these cytokines plays an important role in understanding the patients' immunological status and evaluating patients' prognosis.
