Sequential therapy in renal cell carcinoma

Abstract

Because of the recent approval of several drugs for the treatment of renal cell carcinoma (including sorafenib, sunitinib, temsirolimus, and, in Europe, bevacizumab plus interferon), the use of sequential therapy has become routine practice. There is now evidence that administering these targeted agents sequentially provides clinical benefit by inducing tumor shrinkage and prolonged progression-free survival (PFS) in a large number of patients. However, data regarding overall survival (OS) are still pending. By adding these drugs in an adequate order, one can expect an increase in overall PFS of up to 27 months and a subsequent improvement in the OS of patients with renal cell carcinoma. It has been recently reported that the OS of patients treated with sunitinib in the first-line setting was 26 months. Expecting a survival of 40 months does appear possible based on currently available data, although this assumption will have to be proven in the future. © 2009 American Cancer Society.
