[The value of tumor nephrectomy in metastatic renal cell carcinoma]

In the case of an organ-confined RCC, tumor nephrectomy is the undisputed therapy of choice even though overall 5-year survival has not surpassed the 60% threshold. Further improvement will most likely have to await the development of more effective systemic treatment strategies. For an exclusively surgical therapy of metastatic RCC, tumor nephrectomy, sometimes in combination with metastasectomy, can be applied. However, more commonly used is a multimodality approach consisting of a cytoreductive operation followed by immunotherapy. Alternatively, one may select immunotherapy first followed by adjuvant nephrectomy in the case of a response, or one may proceed directly to immunotherapy only. Long-term survival does not exceed 5-10%, and patient selection appears to have a higher prognostic impact than any treatment strategy available. Concepts and progress in the field clearly are of increasing value for modern oncologic urologists. The current standard, a multimodality treatment of metastatic RCC, in which an operation becomes necessary at a certain point in time, easily justifies a central role for the urologic surgeon.
