摘要
目的评价血清肿瘤标志物CEA、CYFRA21-1、NSE、CA125、CA153、CA199在肺癌诊断和分期中的价值。方法检测肺癌、良性肺疾病和健康人血清中肿瘤标志物含量。CEA采用酶联免疫化学发光法,其余指标采用电化学发光法。结果 CA125、CA153在肺癌和良性肺疾病组水平均较健康对照组升高,CEA、CYFRA21-1、NSE只在肺癌组中升高,CA199在三组间的差异无统计学意义;以良性肺疾病作对照,这5项指标的灵敏度分别为CEA 52%、CYFRA21-1 60%、NSE 10.7%、CA125 48%、CA153 22.7%,特异性相对应分别为90.4%、75.3%、98.6%、72.6%、90.4%;肺癌患者的血清CEA、CYFRA21-1、CA125和肺癌分期呈正相关(P<0.01);通过回归分析得到一个判别式,对肺癌患者是否发生远处转移进行判别,判对率为61.3%。结论 CEA、CYFRA21-1和NSE仍是诊断肺癌最有价值的肿瘤标志物,CEA、CYFRA21-1和CA125有助于肺癌患者的临床分期,CA153、CA199对肺癌的诊断意义不大,可辅助判断患者是否发生远处转移。
