Cytoreductive nephrectomy: A medical oncologist's perspective

The role of cytoreductive nephrectomy (CN) was firmly established in the cytokine era on the basis of 2 randomized studies employing adjunctive interferon therapy. However, systemic therapy for metastatic renal cell carcinoma has evolved markedly over the past decade, with targeted therapies representing the standard of care in the front-line setting. The preponderance of retrospective data generated to date appears to suggest that the benefit of CN is maintained in the targeted therapy era. However, these studies are inherently prone to selection bias and cannot substitute prospective evidence. Herein, we discuss ongoing prospective studies evaluating CN and propose novel strategies to evaluate this surgical technique in the context of an evolving therapeutic landscape.
