血清抗存活素抗体水平在肺部良恶性肿瘤中的对照研究

目的 比较血清抗存活素抗体水平在肺部良、恶性肿瘤之间表达的差异,为将抗存活素抗体作为非小细胞肺癌筛查指标提供依据.方法 采用ELISA法检测健康体检者60名(对照组)、肺良性病变60例(肺良性病变组)、非小细胞肺癌60例(非小细胞肺癌组)血清中抗存活素抗体的含量.结果 抗存活素抗体在对照组11.7%(7/60)]中几乎不表达,在肺良性病变组中表达率为20.0%(12/60)],两者之间表达差异无统计学意义.在非小细胞肺癌组的外周血中阳性表达率68.3%(41/60),与肺良性病变组之间表达差异有统计学意义(x2=38.352,P＜0.01),与对照组比较差异亦有统计学意义(x2=41.798,P＜0.01).结论 抗存活素抗体在健康人群及肺良性病变患者中不表达,而在非小细胞肺癌中高表达,可为非小细胞肺癌诊断提供重要依据,并可作为非小细胞肺癌的筛查指标.

Abstract：

Objective To compare the serum anti-survivin antibody levels between benign and malignant lung tumor,thus to provide evidence for using anti-survivin antibody as an indicator in non-small cell lung cancer.Methods ELISA was used to measure the level of anti-survivin antibody in healthy population(control group,n=60),benign lung tumor patients(benign lung tumor group,n=60) and non-small cell lung cancer patients(non-small cell lung cancer group,n=60). Results The anti-surviving antibody did not express 11.7%(7/60) in the control group and almost no expression 20.0%(12/60) in the benign lung tumor group,with no significant difference between the two groups(P＞0.05).In the non-small cell lung cancer group,the anti-survivin antibody expressed in 41 patients,which was significantly higher than those in the benign lung tumor group(x2=38.352,P＜0.01).Conclusion Anti-survivin antibody does not express in the healthy population and the benign lung tumor patients,whereas shows high expression in non-small cell lung cancer.This finding indicates that anti-survivin antibody can provide important evidence for non-small cell lung cancer diagnosis,and can be used as an indicator for non-small lung cancer screening.
