Abstract
Fifty-five patients with superior sulcus syndrome were treated at the UCLA Medical Center and Wadsworth VA Hospital (Los Angeles) between 1956 and 1985. Twenty-eight underwent surgery, six of whom were found unresectable at the time of thoracotomy. Twenty-one of 22 in the resected group received preoperative irradiation. Twenty-seven patients received radiation only. Surgical morbidity was 21%, and there were two in-hospital deaths. Five-year survival for extended resection patients was 34%. The radiation only group had no 5-year survivors. Factors associated with a worse prognosis include positive margins, N2 disease, and vertebral body involvement. The best results for superior sulcus tumors are obtained by preoperative irradiation followed by en bloc resection of the tumor. In the event complete resection is impossible, radiation has a role in palliation of pain with occasional prolonged survival.
