title: Targeted therapy for metastatic renal cell carcinoma: a home run or a work in progress?
abstract: Recent advances in the understanding of the biology of renal cell carcinoma (RCC) have been translated into clinical treatment options in metastatic disease. The introduction of targeted therapy against the vascular endothelial growth factor (VEGF) pathway and related elements has produced robust clinical effects, exceeding those of historical treatment options. Sunitinib (Sutent) and bevacizumab (Avastin) plus interferon have established roles in the initial treatment of metastatic RCC. Sorafenib (Nexavar) is established for cytokine-refractory RCC and is being explored in other settings. Temsirolimus (Torisel) is the only agent to extend overall survival to date, although this finding has been restricted to a poor-risk population. Several clinical questions have thus emerged in regard to the optimal timing, type, and sequence of targeted therapy in metastatic RCC. Novel agents targeting the VEGF or alternative pathways have also emerged and are beginning to undergo clinical testing.
