Systemic therapy for patients with advanced, unresectable or metastatic renal cell carcinoma: moving to guidelines
AbstractUntil recently, patients with advanced, unresectable or metastatic renal cell cancer (RCC) had very few therapeutic options. Cytokine therapy, consistingmainly of interferon-a and interleukin-2, was considered the mainstay of therapy. A better understanding of the biology of RCC has led to the development of novel therapeutic agents that target angiogenesis. Inactivation of thevon Hippel-Lindau tumour-suppressor gene VHL, which is present in the vast majority of clear-cell RCC tumours, leads to overexpression of the vascular endothelial growth factor, which in turn promotes angiogenesis. Recent observationsfrom a number of positive studies with agents such as sunitinib malate, sorafenib, temsirolimus and bevacizumab have led to a rapid and exciting change in the standard of care for patients with advanced renal cell carcinoma. This article reviews these agents in the context of their use in clinical practiceand provides suggestions about the appropriateness of various agents inspecific clinical situations.
