Surgical resection for metastatic neoplasms of the lung: experience at the University of Minnesota Hospitals.


Pulmonary resection for metastatic disease in 167 patients undergoing 207 thoracotomies resulted in a cumulative survival rate of 29% at five years and 20% at 10 years, with an operative mortality of 0.6%. The most favorable prognosis was associated with testicular and renal cell carcinomas and sarcomas. Less favorable tumors were malignant melanoma, carcinoma of the colon and rectum, and cervix uteri. A significant factor influencing survival was duration of disease-free interval with a 50% five-year survival rate in patients whose primary tumor was treated over five year ago. Patients with multiple pulmonary metastases had a five-year survival rate of 27% vs. 22% of patients with solitary metastases. Of 23 patients with tumor extending to the chest wall, diaphragm, or pleura, only two survived five years. Of 26 patients with mediastinal involvement none survived two years.
