    Author: Stewart JR, Carey JA, Merrill WH, Frist WH, Hammon JW, Bender HW.
    Journal: Am Surg; 1992 Feb; 58(2):100-3. PubMed ID: 1550299.
    Abstract:
    From January 1969 through December 1989, 63 patients had 69 operations for pulmonary metastases. Patients ranged in age from 1 to 75 years; there were 36 men and 27 women. Metastasectomy was accomplished through a thoracotomy incision in 59 cases (5 staged, bilateral), and median sternotomy was used in 10 instances. Wedge resection was performed in 54 patients, with segmentectomy in 2, lobectomy in 12, and pneumonectomy in 1. There were no operative deaths. Multiple metastases were present in 29 patients, and a single metastasis in 34. Follow-up ranges from 2 to 204 months (mean = 42 months). Thirty-eight patients remain alive; thirty are free of disease and eight have developed other metastases. Actuarial survival at 5, 10, and 15 years is 40 (CL [confidence limits] 49,31), 36 (CL 44,26), and 24 (CL 35,13) per cent, respectively. Mean actuarial survival is 84 months, and median survival is 58 months. There is no difference in survival whether metastases were single or multiple. Survival is significantly less in groups with primary sarcoma and melanoma (P = .012). While pulmonary metastases may be a manifestation of terminal disease, metastasectomy has an important role in the multidisciplinary management of selected patients when metastatic disease is confined to the lung. Prolonged survival may be achieved in many patients.
