The management and outcome for superior sulcus tumors have remained unchanged for 40 years. The rarity of these tumors has led to varying treatment techniques spanning decades, from which no solid conclusions can be drawn. Recent advances in combined-modality therapy have offered the first inkling that a paradigm shift is on the horizon. Here, we review the history and new advances in treating this challenging pulmonary neoplasm.

He initially thought that these tumors arose from epithelial rest cells from the fifth brachial cleft. Eight years later, Tobias [2] and Pancoast [3] simultaneously, correctly recognized that bronchogenic carcinoma was the primary cause of this syndrome.

HISTORYSuperior sulcus tumors usually arise in the apex of the lung and may invade the second and third ribs, the brachial plexus, the subclavian vessels, the stellate ganglion, and adjacent vertebral bodies [4]. Pancoast syndrome is characterized by pain, which may arise in the shoulder or chest wall or radiate to the neck. Pain characteristically radiates to the ulnar surface of the hand. Horner's syndrome, which is composed of ptosis, meiosis, and anhydrosis, results from invasion of the paravertebral sympathetic chain. Weakness and atrophy of the hand and parasthesias are a common clinical finding resulting from invasion into the C8 and T1 roots of the brachial plexus. More infrequent manifestations include supraclavicular adenopathy, superior vena cava syndrome, and involvement of the phrenic or laryngeal nerves [5].Prior to the 1950s, superior sulcus tumors were uniformly fatal. Chardack and MacCallum [6] reported the The Oncologist ® Lung Cancer
