The role of surgical resection of pulmonary metastasis in selected patients is widely accepted, and a survival advantage of aggressive surgical therapy has been demonstrated. Surgical series have demonstrated 5-year survival of 25-42% in the surgical treatment of pulmonary metastasis from different primaries including colorectal cancer osteogenic sarcoma, melanoma, and others. In a prospective study of 5,206 cases of lung metastasectomy, the International Registry of Lung Metastases reported an actuarial survival of 36% at 5 years and 26% at 10 years. These results compared favorably with those who had an incomplete resection achieving a survival of 13% at 5 years and 7% at 10 years.
