Secondary pulmonary malignancy.

Patients with pulmonary metastases were previously relegated to palliative medical management. Since the first metastasectomies in the nineteenth century, general acceptance of this technique has occurred. Although, initially, indications for resection of pulmonary metastases were limited to patients with solitary nodules, over time, indications have broadened to include multiple lesions, recurrent disease, and nearly all histologies. With appropriate patient selection and the absence of extrathoracic disease, survival may be improved. For patients with disseminated and symptomatic disease, surgical therapy may also provide some relief.
