A quarter of patients with clinical N1 (cN1) non-small cell lung cancer (NSCLC) based on positron emission tomography–computed tomography (PET-CT) imaging have occult mediastinal nodal involvement (N2 disease). In a prospective study, endosonography alone had an unsatisfactory sensitivity (38%) in detecting N2 disease. The current prospective multicentre trial investigated the sensitivity of preoperative mediastinal staging by video-assisted mediastinoscopy (VAM) or VAM-lymphadenectomy (VAMLA). Consecutive patients with operable and resectable (suspected) NSCLC and cN1 after PET-CT imaging underwent VAM(LA). The primary study outcome was sensitivity to detect N2 disease. Secondary endpoints were the prevalence of N2 disease, negative predictive value (NPV) and accuracy of VAM(LA). Out of 105 patients with cN1 on imaging, 26% eventually developed N2 disease. Invasive mediastinal staging with VAM(LA) had a sensitivity of 73% to detect N2 disease. The NPV was 92% and accuracy 93%. Median number of assessed lymph node stations during VAM(LA) was 4 (IQR 3–5), and in 96%, at least three stations were assessed. VAM(LA) has a satisfactory sensitivity of 73% to detect mediastinal nodal disease in cN1 lung cancer, and could be the technique of choice for pre-resection mediastinal lymph node assessment in this patient group with a one in four chance of occult-positive mediastinal nodes after negative PET-CT. Videomediastinoscopy reaches a sensitivity of 73% detecting N2 disease in cN1 NSCLC patients; N2 prevalence is 26% http://ow.ly/VrzL30gIOWm

视频纵隔镜在临床 N1 非小细胞肺癌中的纵隔分期:一项前瞻性多中心研究

基于正电子发射断层扫描 - 计算机断层扫描 (PET-CT) 成像的临床 N1 (cN1) 非小细胞肺癌 (NSCLC) 患者中有四分之一有隐匿性纵隔淋巴结受累(N2 疾病)。在一项前瞻性研究中,单独的超声内镜在检测 N2 疾病方面的敏感性不令人满意 (38%)。目前的前瞻性多中心试验通过视频辅助纵隔镜检查 (VAM) 或 VAM 淋巴结切除术 (VAMLA) 研究了术前纵隔分期的敏感性。PET-CT 成像后可手术和可切除(疑似)NSCLC 和 cN1 的连续患者接受 VAM(LA)。主要研究结果是检测 N2 疾病的敏感性。次要终点是 N2 疾病的患病率、阴性预测值 (NPV) 和 VAM(LA) 的准确性。在 105 名影像学检查为 cN1 的患者中,26% 最终发展为 N2 疾病。VAM(LA) 侵入性纵隔分期检测 N2 疾病的敏感性为 73%。NPV 为 92%,准确度为 93%。VAM(LA) 期间评估的淋巴结站点中位数为 4 (IQR 3–5),并且在 96% 中,至少评估了三个站点。VAM(LA) 在检测 cN1 肺癌的纵隔淋巴结疾病方面具有令人满意的 73% 的敏感性,并且可能是该患者组切除前纵隔淋巴结评估的首选技术,有四分之一的机会出现隐匿性阳性PET-CT 阴性后的纵隔淋巴结。视频纵隔镜在 cN1 NSCLC 患者中检测 N2 疾病的灵敏度达到 73%;N2 流行率为 26% http://ow.ly/VrzL30gIOWm VAM(LA) 期间评估的淋巴结站点中位数为 4 (IQR 3–5),并且在 96% 中,至少评估了三个站点。VAM(LA) 在检测 cN1 肺癌的纵隔淋巴结疾病方面具有令人满意的 73% 的敏感性,并且可能是该患者组切除前纵隔淋巴结评估的首选技术,有四分之一的机会出现隐匿性阳性PET-CT 阴性后的纵隔淋巴结。视频纵隔镜在 cN1 NSCLC 患者中检测 N2 疾病的灵敏度达到 73%;N2 流行率为 26% http://ow.ly/VrzL30gIOWm VAM(LA) 期间评估的淋巴结站点中位数为 4 (IQR 3–5),并且在 96% 中,至少评估了三个站点。VAM(LA) 在检测 cN1 肺癌的纵隔淋巴结疾病方面具有令人满意的 73% 的敏感性,并且可能是该患者组切除前纵隔淋巴结评估的首选技术,有四分之一的机会出现隐匿性阳性PET-CT 阴性后的纵隔淋巴结。视频纵隔镜在 cN1 NSCLC 患者中检测 N2 疾病的灵敏度达到 73%;N2 流行率为 26% http://ow.ly/VrzL30gIOWm 并且可能是该患者组切除前纵隔淋巴结评估的首选技术,PET-CT 阴性后有四分之一的机会出现隐匿性纵隔淋巴结。视频纵隔镜在 cN1 NSCLC 患者中检测 N2 疾病的灵敏度达到 73%;N2 流行率为 26% http://ow.ly/VrzL30gIOWm 并且可能是该患者组切除前纵隔淋巴结评估的首选技术,PET-CT 阴性后有四分之一的机会出现隐匿性纵隔淋巴结。视频纵隔镜在 cN1 NSCLC 患者中检测 N2 疾病的灵敏度达到 73%;N2 流行率为 26% http://ow.ly/VrzL30gIOWm
