[Surgical treatment of pulmonary metastases of sarcoma].

Lungs are the most common target of metastases from osteogenic and soft tissue sarcomas. Metastases can be successfully treated by surgery. Only a few patients with non treated pulmonary metastases from sarcomas are alive after 5 years. In fact, without surgery the 1-year mortality is 50\%. The number of metastases, the site in one or both lungs, the disease-free period and the tumoral doubling time have important prognostic significance. The authors report two interesting cases successfully treated with surgical therapy.
