摘要
目的 分析糖类抗原125(CA125)、糖类抗原199(CA199)、细胞角蛋白19片段(CYFRA-21)、癌胚抗原(CEA)对非小细胞肺癌(NSCLC)患者脑转移的诊断价值.方法 选取NSCLC患者共96例,根据其是否存在脑转移将其划分为转移组(32例)及未转移组(64例);另将行体检的75例健康体检者纳入健康组.抽取全部研究对象的晨起空腹静脉血,检测血清CA125、CA199、CYFRA-21及CEA水平.绘制受试者工作曲线(ROC),分析CA125、CA199、CYFRA-21、CEA联合检测对NSCLC患者脑转移的诊断价值.结果 转移组的CA125、CA199、CYFRA-21、CEA水平高于未转移组、健康组,且未转移组的CA125、CA199、CYFRA-21、CEA水平高于健康组,差异有统计学意义(P<0.05).ROC结果显示,CA125、CA199、CYFRA-21、CEA联合检测诊断NSCLC患者脑转移的曲线下面积(AUC)高于CA125、CA199、CYFRA-21、CEA单独诊断.结论 CA125、CA199、CYFRA-21、CEA在出现脑转移的NSCLC患者血清中的表达较高,四者联合检测能够有效诊断出患者是否存在脑转移,具有一定的诊断价值.
Abstract
Objective To analyze the diagnostic value of carbohydrate antigen 125(CA125),carbohydrate antigen 199(CA199),cytokeratin 19 fragment(CYFRA-21),and carcinoembryonic antigen(CEA)for brain metastasis in non-small cell lung cancer(NSCLC)patients.Methods A total of 96 NSCLC patients were selected and divided into a metastatic group(32 cases)and a non metastatic group(64 cases)based on the presence of brain metastasis;75 healthy examinees who underwent physical examinations were included in the health group,and fasting venous blood from all study subjects was extracted in the morning,and serum CA125,CA199,CYFRA-21,and CEA levels were detected.Receiver operating curve(ROC)was plotted to analyze the di-agnostic value of combined detection of CA125,CA199,CYFRA-21,and CEA for brain metastasis in NSCLC patients.Results The levels of CA125,CA1 99,CYFRA-21,and CEA in the transfer group were higher than those in the non transfer group and the healthy group,and the levels of CA125,CA199,CYFRA-21,and CEA in the non transfer group were higher than those in the healthy group,with statistical significance(P<0.05);The ROC results showed that the area under the curve(AUC)for the com-bined detection of CA125,CA199,CYFRA-21,and CEA in diagnosing brain metastases in NSCLC patients was higher than that of CA125,CA199,CYFRA-21,and CEA alone.Conclusion CA125,CA199,CYFRA-21,and CEA are highly expressed in NSCLC patients with brain metastases.The combination of the four can effectively diagnose the presence of brain metastases in patients and has certain diagnostic value.
