Contemporary management of superior pulmonary sulcus (Pancoast) lung tumors.

Abstract

For more than three decades following the initial report by Shaw et al. in 1961, the standard treatment of Pancoast lung tumors consisted of induction radiotherapy followed by en bloc resection through a posterolateral thoracotomy. Overall 5-year survival rates with this regime were typically 30 to 40%, with poor prognosis in patients with positive mediastinal lymph nodes, T4 involvement, or incomplete resection. During the past decade, advancements in surgical technique and adjuvant therapy have improved the safety and completeness of resection as well as the probability of long-term survival. Alternative surgical approaches have been developed to facilitate more complete resection of tumors involving subclavian vessels and brachial plexus, and aggressive vertebral body resection has been performed in conjunction with neurosurgeons. Arguably the most important advance in the treatment of Pancoast tumors has been the recognition that induction chemoradiation substantially improves both the rate of complete resection and medium-term survival.
