Advanced Renal Cell Carcinoma

Current and Emerging Management Strategies
Therapy In Practice

Abstract

Management of renal cell carcinoma (RCC) has made considerable progress in recent years, and new emerging strategies are being developed. On the basis of the results of two randomised studies in the early 2000s, nephrectomy has now become the standard as cytoreductive surgery before embarking on systemictreatment with cytokines. Interleukin (IL)-2 and interferon were the standard treatment in metastatic RCC (MRCC) until 2006. The efficacy of these two drugs, which have now been used for >20 years in MRCC, is still controversial. On the basis of many studies, these drugs should not be given to patients with a poor prognosis. In patients with good prognostic factors, a cytokine-based regimen should remain the standard as either a high-dose IL-2 or subcutaneous regimen. In patients with intermediate risk, the results of the French Percy Quattro study encourage the use of new targeted therapies as first-line therapy.

Development of targeted therapies in RCC has been necessary largely because the Von Hippel-Lindau (VHL) gene is often mutated in sporadic RCC. VHL protein abnormalities lead to accumulation of hypoxia-inducible factor (HIF)-α and activation of a series of genes, including vascular endothelial growth factor (VEGF), thus inducing angiogenesis. Results from many recent studies with new agents that block the VEGF pathway have been reported and offer new strategic options for patients with MRCC. Sunitinib and sorafenib, two tyrosine kinase inhibitors, improve progression-free survival in RCC compared with standard treatment and have been recently approved. Temsirolimus, a mammalian target of rapamycin inhibitor regulating HIF-α, improves survival in RCC patients with poor risk features. Bevacizumab, a monoclonal antibody against VEGF, has shown very promising efficacy. Overall, treatment of MRCC is currently moving from the cytokine era to the targeted agent era. However, many questions still remain regarding the efficacy of combination treatments and on the best way to achieve complete remission, which is probably the best hope of curing MRCC.
