Preoperative Evaluation and Indications for Pulmonary Metastasectomy.

Most patients with pulmonary metastases will not be candidates for pulmonary metastasectomy. Preoperative evaluation determines whether a patient is both fit enough for surgery and has disease that is actually resectable. Both components are necessary for patients who undergo resection with curative intent. In general, to be considered for pulmonary metastasectomy, patients must fit the following criteria: the primary disease site and any extrathoracic disease are both controlled; complete resection of pulmonary involvement is achievable with adequate pulmonary reserve; and there are no effective medical therapies.
