BACKGROUND: The aim of this single-center study was to analyze factors predicting long-term outcomes following surgical resection of pulmonary metastases in patients with renal cell carcinoma. METHODS: Two hundred two consecutive patients entered the study. Overall survival was analyzed by the Kaplan-Meier method. Multivariate analysis was performed using Cox regression models. RESULTS: In 175 cases (87%), curative resection of the pulmonary metastases was achievable, with median survival of 43 months. Multivariate analysis revealed complete metastasectomy (R0), metastasis size >3 cm, positive nodal status of the primary tumor, synchronous metastases, pleural infiltration, and tumor-infiltrated hilar or mediastinal lymph nodes as independent prognostic factors for survival. On the basis of these findings, a new scoring system (the Munich score) was established to predict survival, which discriminates 3 groups with low, intermediate, and high risk for poor outcomes (median survival, 90, 31, and 14 months, respectively, P < .001). CONCLUSIONS: The aim of the Munich score is to define patients with low, intermediate, and high risk for poor survival and will help identify patients who may benefit from further adjuvant therapy.
