Abstract
Background: Metastasectomy has been proved to be an opportunity for long-term survival for patients with various neoplasms with pulmonary metastases. A retrospective study was performed to analyze the results and identify the prognostic factors of surgical treatment for pulmonary metastases. Methods: From 1991 to 2003, a total of 73 patients who underwent surgical treatment for pulmonary metastases at the Kaohsiung Veterans General Hospital were enrolled for analysis. Results: The overall 5-year survival rate was 25.1%. The operation-related mortality rate was 2.74%. Gender, origins of the primary cancers, number of pulmonary metastases, and surgical procedures had no significant effect for those patients who underwent pulmonary metastasectomies. However, patients who had a disease-free interval longer than 36 months had a better 5-year survival rate than those who had a shorter disease-free interval (29.6% vs. 10.5%). Conclusion: Pulmonary metastasectomy is a safe and potentially curative procedure. The disease-free interval is an important prognostic factor for patients with pulmonary metastases.
