Abstract: 目的:探讨肿瘤标记物在孤立性肺结节(solitary pulmonary nodule,SPN)中的诊断价值.方法:选择北京大学第一医院2011年1月至2013年1月经手术病理明确诊断的SPN患者175例,检测血清癌胚抗原(carcinoembryonic antigen,CEA)、鳞状上皮细胞癌抗原(squamous cell carcinoma,SCC)、神经元特异性烯醇化酶(neuron-specific enolase,NSE)和细胞角蛋白19片段(cytokerantin-19-fragment,CYFRA21-1)水平,采用ROC曲线及曲线下面积比较诊断价值,计算诊断灵敏度、特异性和准确度.结果:175例SPN患者中,肺癌125例,良性病变50例.恶性SPN组血清CEA、SCC和CYFRA21-1水平明显高于良性SPN组(P<0.05),恶性SPN组CEA、SCC和CYFRA21-1以及4种标记物联合检测的阳性率均高于良性SPN组(P<0.05).CEA、NSE、SCC和CYFRA21-1的ROC曲线下面积分别为0.633±0.045、0.494±0.047、0.664±0.042和0.711 ±0.041.4项指标联合检测对恶性SPN诊断的灵敏度和特异度分别为52.0%和76.0%.吸烟SPN患者中,良恶性SPN间CEA、NSE、SCC和CYFRA21-1的阳性率无明显差异.结论:血清CEA、SCC和CYFRA21-1在恶性SPN中阳性率增高,对于恶性SPN有一定的诊断价值.
