Long-term results of surgical management of pulmonary metastases from renal cell carcinoma.

ABSTRACT

BACKGROUND: Metastatic renal cell carcinoma (RCC) has a poor prognosis and conventional treatments such as chemoradiotherapy show little efficacy. Surgical resection of pulmonary metastases from RCC is a widely accepted treatment, even if selection criteria based on prognostic factors have still not been defined. The aim of this study was to determine the long-term survival, clinical outcome and prognostic factors after surgery. METHODS: Between 1988 and 2004, 59 patients underwent resection of pulmonary metastases from RCC. Univariate and multivariate analysis of prognostic factors was carried out. RESULTS: Complete resection was achieved in 54 (91.5 %) patients. No intra- or postoperative mortality occurred, 5 (8.5 %) patients experienced postoperative complications. Overall, the 1-, 3-, and 5-year survival rates were 86.5 %, 63 % and 53 %, respectively. Age at the time of pulmonary resection was found to be the only independent factor influencing prognosis. CONCLUSION: Pulmonary resection of metastases from RCC is a safe and effective treatment associated with a low morbidity and mortality and with high long-term survival. The lack of other effective therapies suggests use of the surgical approach whenever possible.
