Less than 10% of patients at autopsy have metastatic disease confined to the lungs.

Endobronchial lesions are always primary lung tumors.

CT scan can underestimate the number of malignant nodules by up to 75%.

A solitary lesion is more likely to be metastatic if the primary tumor is breast carcinoma.

Percutaneous biopsy should be performed in order to plan operative management.

Disease-free interval has not been shown to have prognostic value for survival.

Patients with a greater number of metastatic nodules have poorer survival..

CEA levels do not affect 5-year survival after resection of metastatic colon carcinoma.

Metastatic head and neck cancers have poor outcome after pulmonary resection.
