The surgical management of pulmonary metastasis: current concepts.

Lung metastases have been found in 25-30% of all patients with cancer at autopsy. Those patients satisfying criteria for surgical resection represent a much smaller subgroup. Given the potentially curative nature of pulmonary metastasectomy in the absence of disseminated disease, it has become widely accepted as an important treatment option for a variety of malignancies with metastasis to the lungs. A standardized approach remains unfounded however, given limited numbers of patients, various histologic subtypes and few published studies utilizing randomized prospective methodology.Ultimately, the development of metastasis represents a major determinant of survival for patients with cancer. Pulmonary metastasectomy is an important treatment modality for patients with metastatic pulmonary disease. The indications for pulmonary metastasectomy and the surgeon's role in pulmonary metastatic disease continue to evolve. Future prospective studies and the compilation of comparable data yielding prognostic factors for specific histologies will better define indications for resection.
