The value of cervical mediastinoscopy.
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.
