Which patients with carcinoma of the superior pulmonary sulcus are suitable for surgery? Is surgery suitable for patients whose tumors have already invaded blood vessels and brachial plexus nerves? First, the patient should not have distant metastasis, including metastasis to bone, brain, adrenal gland, liver and other important areas; second, the patient’s cardiopulmonary function can tolerate surgery; third, the local invasion of the superior pulmonary sulcus, especially the nerve invasion, should be carefully evaluated. Among the brachial plexus nerves, we look more at the cervical 8 nerve and the thoracic 1 nerve. If the tumor invasion exceeds the cervical 8 nerve, the patient will experience muscle weakness or loss of muscle strength in the affected upper extremity. Therefore, when the tumor invades more than the cervical 8 nerve, such patients are generally less suitable for surgery. In addition, if the cancer of the superior pulmonary sulcus invades the spinal cord in the back, it is also not suitable for surgery. Fourth, tumor invasion of blood vessels is generally considered to be operable. Nowadays, the technology of artificial blood vessel is mature, and in the supraglottic sulcus carcinoma, the main artificial blood vessel that needs to be replaced is the subclavian artery in the apical part of the lung, which usually takes about 20 minutes.
