Renal cell cancer: State of the art in adjuvant therapy

Renal cell cancer is fastly growing in incidence worldwide. No adjuvant therapy has been unarguably proven feasible so far, although an autologous vaccine has achieved a significant benefit. An effective agent in adjuvant therapy against renal cell cancer must achieve several goals. It should be relatively non toxic, have estabilished efficacy in the metastatic setting, and have demonstrated efficacy against the standard of care in randomized phase III trials. The development of adjuvant therapy requires the properly identification of patients at highest risk of relapse, as potential benefactors of adjuvant therapy development. Our ability to predict when and where patients will recur has much room for improvement. Therefore several models and nomograms including the most important prognostic and predictive factors have been developed. Nevertheless, during the past few years, major advances have been made concerning the metastatic setting of the disease with the arrival of new drug classes such as tyrosine kinase inhibitors and monoclonal antibodies, strongly improving overall and progression free survivals, renewing hopes on activity regarding the adjuvant therapy. Several trials are today in progress to evaluate the effectiveness of antiangiogenic agents in this area. An overall review of the completed and upcoming trials and patents shall be discussed here. © 2010 Bentham Science Publishers Ltd.
