Aims: To investigate the surgical approach and outcomes, as well as prognostic factors for pulmonary metastasectomy. Methods: Clinical data of 201 patients treated by pulmonary metastasectomy between January 1990 and December 2009 were retrospectively reviewed. One hundred thirty three patients were received an approach of thoracotomy while 68 with video-assisted thoracoscopic surgery (VATS). There were 54 lobectomies, 139 wedge resections and 8 pneumonectomies. Hilar or mediastinal lymph nodes dissection or sampling was carried out in 38 patients with lobectomy. The Kaplan-Meier method was used for the survival analysis. Cox proportional hazards model was used for multivariate analysis. Results: The 5 years survival rate of patients after metastasectomy was 50.5%, and the median survival time was 65.9 months. The median survival time of patients with hilar or mediastinal lymph nodes metastasis was 23 months. By univariate analysis, significant prognostic factors included disease-free interval (DFI), number of metastases, number of affected lobe, surgical approach (open vs. VATS) and pathology types. DFI, number of metastases, and pathology types were revealed by Cox multivariate analysis as independent prognostic factors. Conclusion: Surgical resection of pulmonary metastases is safe and effective. Palpation of the lung is still seen as necessary to detect the occult nodule. More accurate and sensitive pre-operative mediastinal staging are required.
