Despite the lack of randomized trials, lung metastasectomy is currently proposed for colorectal cancer patients under certain conditions. Many retrospective studies have reported different prognostic factors of poorer survival, but eligibility for pulmonary metastasectomy remains determined by the complete resection of all pulmonary metastases. The aim of this review is to clarify which pre-operative risk factors reported in systematic reviews or meta-analysis are determinant for survival in colorectal metastatic patients. Different criteria have been now identified to select which patient will really benefit from lung metastasectomy.
