摘要
目的探讨纵隔镜检查术在纵隔或肺门淋巴结PET/CT(positron emission tomography-computed tomography)代谢阳性的非小细胞肺癌中(non-small cell lung cancer,NSCLC)的应用价值。方法回顾性分析纵隔镜检查术前PET/CT纵隔或肺门淋巴结异常的NSCLC病例,以病理结果为标准,计算纵隔镜检查术诊断纵隔淋巴结转移的敏感度、特异性、阳性预测值、阴性预测值和准确率以及PET/CT的假阳性率。结果 2007年4月—2011年12月期间,73例患者符合条件。纵隔镜检查术诊断纵隔淋巴结转移的敏感度、特异性、阳性预测值、阴性预测值和准确率分别为91.3%、100%、100%、87.1%和94.5%。PET/CT诊断纵隔淋巴结转移的假阳性率高达30.8%。如果将非巨块型纵隔淋巴结代谢升高且双侧肺门淋巴结代谢升高定义为纵隔淋巴结阴性,其阳性预测值升高至81.1%。结论在PET/CT纵隔或者肺门淋巴结代谢升高的NSCLC,纵隔镜检查术诊断纵隔淋巴结转移的敏感度和特异性高。对PET/CT代谢阳性的纵隔淋巴结需要病理确认,特别是合并双侧肺门对侧性代谢增高的纵隔淋巴结。
