非小细胞肺癌(non-small cell lung cancer,NSCLC)术前纵隔淋巴结分期可分为无创性影像学分期和有创性外科学分期。无创性分期技术对纵隔淋巴结术前分期效能较差。其中计算机断层成像(CT)提供了良好的解剖图像已作为常规检查,磁共振成像(MRI)与磁共振扩散加权成像(DWI)目前并未得到普遍应用,电子发射计算机体层显像-X线计算机体层成像(PET-CT)作为最准确的无创分期检查仍有较高的假阳性率及假阴性率。有创性分期技术对纵隔淋巴结分期安全有效。其中纵隔镜术目前作为纵隔淋巴结分期诊断的金标准,超声内镜针吸活检术及电视胸腔镜手术(VATS)亦在临床有效应用。ⅢA期肺癌诱导治疗后的纵隔淋巴结再分期较为困难,首选有创性分期方法。
Non-small cell lung cancer (NSCLC) preoperative mediastinal lymph node staging can be divided into non-invasive imaging staging and invasive surgical staging. Noninvasive staging techniques have poor performance on preoperative mediastinal lymph node staging. Among them, computed tomography (CT) provides a good anatomical image that has not been widely used as a routine examination. Magnetic resonance imaging (MRI) and magnetic resonance diffusion-weighted imaging (DWI) are currently not widely used. Electron emission computed tomography Computed tomography (PET-CT) as the most accurate noninvasive staging examination still has a high false positive rate and false negative rate. Invasive staging techniques are safe and effective for staging mediastinal lymph nodes. Among them, mediastinoscopy is currently used as the gold standard for the diagnosis of mediastinal lymph node staging, and endoscopic ultrasonography and video-assisted thoracoscopic surgery (VATS) are also clinically effective. Stage IIIA lung cancer induction therapy after mediastinal lymph node recanalization more difficult, the preferred method of invasive staging.
