The reliability of mediastinoscopy as described by Carlens was evaluated in 170 patients with lung cancer. When the primary tumour was located in the left upper lobe, the result of the mediastinoscopy was false-negative in 12 (31%) out of 39 patients. Other invasive procedures, such as left parasternal mediastinoscopy, might be more accurate in these patients.
在170例肺癌患者中评估了卡伦斯所描述的纵隔镜检查的可靠性。当原发性肿瘤位于左上叶时，39例患者中有12例（31%）纵隔镜检查结果为假阴性。对于这些患者，其他侵入性检查，如左胸骨旁纵隔镜检查，可能更准确。
