Cytoreductive nephrectomy in patients with metastatic renal cell carcinoma in the era of targeted therapy: a bibliographic review.

PURPOSE: To evaluate the role of cytoreductive nephrectomy (CN) in metastatic renal cell carcinoma (mRCC), against a background of lack of evidence following the introduction of targeted therapy.

METHODS: A literature review was performed in January 2017 using the MEDLINE/PubMed and EMBASE databases. The PRISMA guidelines were followed for conduct of the study. Two authors independently screened the 270 papers retrieved from the search, and the finally selected publications were identified by consensus between the two reviewers. A total of 55 studies were included in the present review.

RESULTS: Globally, the indications for CN have decreased over recent years. Although current guidelines consider CN an adequate option in selected patients based on prospective studies in the cytokine era, evidence for CN in the era of targeted therapy is based on retrospective studies only.

CONCLUSIONS: The results of ongoing prospective studies are still awaited. Retrospective data suggest that young male patients with oligometastatic disease and a good performance status can be considered suitable surgical candidates who may benefit from CN.
