ABSTRACT

BACKGROUND: In patients with isolated meta- or synchronous pulmonary metastases from renal cell cancer, lung metastasectomy could be an appropriate treatment option after successful treatment of primary cancer. OBJECTIVES: Presentation of lung metastasectomy as a treatment option in patients with pulmonary metastatic renal cell cancer and the postoperative outcome. Description of alternative treatment modalities focusing on "targeted therapies". MATERIALS AND METHODS: Systematical literature research and qualitative analysis of studies on patients undergoing lung metastasectomy after primary nephrectomy published since 01 January 2000. We assessed operative findings, survival data, and prognostic factors. RESULTS: Pulmonary metastasectomy results in a median postmetastasectomy survival of 26-94 months. The 5­year survival rates vary between 33 and 58%. The patients' prognosis depends on a prolonged disease-free interval and complete resection of all suspected metastases. In particular, number and location of lung metastases should play a minor role for the indication for lung metastasectomy. CONCLUSIONS: Pulmonary metastasectomy should be considered the treatment of choice in selected patients with successfully resected primary cancer showing no evidence of extrapulmonary metastases and having guaranteed operability and complete resection.
