[Pulmonary metastasectomy]

The lung is the second site of metastasis after the liver, affecting 30 to 40 % of all patients with a malignant tumor. Chemotherapy seems to be ineffective for some types of tumor. Although there are no prospective randomized studies that confirm the benefit of surgical pulmonary metastasectomy, many studies have shown the existence of a group of patients with pulmonary metastases who benefit from a complete resection for curative purposes in case of complete resection of lung metastases. Different approaches are known to achieve a complete resection with maximum lung parenchyma sparing. Minimal invasive approaches appear to offer a better quality of life and have equivalent oncologic outcomes compared to the open approach.
