摘要 目的探讨联合检测血清肿瘤标志物癌胚抗原(CEA)、神经元特异性烯醇化酶(NSE)、细胞角蛋白19片段(CYFRA21-1)及经纤维支气管镜肺活检(TBLB)对周围型肺癌的诊断价值。方法回顾性分析336例病理确诊的周围型肺癌患者术前的血清CEA、NSE、CYF211水平及TBLB检查结果,分析不同病灶直径大小、病理类型时4项指标及联合检测的阳性率。结果 336例周围型肺癌患者中,CEA、NSE、CYFRA21-1及TBLB的检出率分别为51.79%、35.12%、44.94%及61.61%,与四项联合检测的检出率(85.12%)比较,差异有统计学意义(χ^2=86.4、175.2、119.3、47.5,P均〈0.01)。当病灶直径〈2 cm时,CEA、NSE、CYFRA21-1及TBLB的检出率分别为28.89%、26.67%、33.33%及10.96%;四项联检检出率为51.11%,高于CEA、NSE及TBLB单独检测的检出率,差异有统计学意义(χ^2分别为4.6、5.7和9.6,P均〈0.05)。随着病灶直径的增大,TBLB的检出率呈现明显的上升趋势。四项联检阳性检出率高于单项检测。病灶直径为2~6 cm和〉6 cm时,四项联检的检出率均高于各项指标单独检测(P均〈0.05)。鳞癌、腺癌组四项联检的阳性检出率均明显高于单独检测(P均〈0.05);小细胞肺癌组除NSE外,其余指标单独检测阳性率均低于四项联检(P均〈0.05);未分化肺癌组四项联检阳性率较CEA单项检测阳性率低,差异有统计学意义(P〈0.05)。结论 CEA、NSE、CYFRA21-1及TBLB对诊断周围型肺癌有重要价值,四项联检可进一步提高周围型肺癌的检出率。
