Surgical management of superior sulcus tumors.
Superior sulcus tumor refers to any primary lung cancer presenting with constant pain in the nerve distribution of the eighth cervical, first and second thoracic nerve roots and Horner's syndrome caused by invasion of the stellate ganglion. The pain is steady, severe, and unrelenting, involving the shoulder, the vertebral margin of the scapula and ulnar distribution of the arm to the elbow and finally to the ulnar surface of the forearm, and the small and ring fingers of the hand (Pancoast-Tobias syndrome). Weakness and atrophy of the hand muscles can also occur as the lesions spreads to involve the first and second ribs and vertebrae. Radiologically, there is a small shadow at the extreme apex of the lung with rib and possible vertebral body invasion. Pulmonary symptoms are less frequent because of the peripheral location of the lesions. Since Shaw and Paulson approached superior sulcus tumors in 1961 by using preoperative radiation-therapy (30 to 45 Gy in four weeks including the primary tumor, mediastinum and supraclavicular region) followed by surgical resection, this radiosurgical approach shortly became the standard treatment yielding better disease control and survival than that offered by other treatment modalities. It has now become evident that en bloc resection of the chest wall, involved adjacent structures as well as lobectomy must be considered the standard surgical approach for superior sulcus tumors combined with external radiation (preoperative, postoperative, or both). The goal of the operation is the complete and en bloc resection of the upper lobe in continuity with the invaded ribs, transverse processes, subclavian vessels, T1 nerve root, upper dorsal sympathetic chain and prevertebral muscles.
