Reconciling the Role of Vascular Endothelial Growth Factor-Targeted Therapies in Adjuvant Renal Cell Carcinoma Treatment

Abstract

Abstract. Up to 40% of patients with high risk, localized RCC will relapse after nephrectomy and are at risk of eventually succumbing to the disease. Historically, phase 3 clinical trials failed to demonstrate meaningful benefit of adjuvant therapy in RCC, likely because these early trials used treatments that did not demonstrate meaningful clinical efficacy in mRCC. However, the clear clinical activity demonstrated by VEGF-TKIs in mRCC patients renewed the promise of adjuvant therapy. ASSURE, S-TRAC, and PROTECT are the first three trials to examine the clinical efficacy of 1 year of adjuvant VEGF-TKI therapy in patients with high-risk RCC following nephrectomy. In this review we reconcile the results of these studies and explore the future of adjuvant RCC therapy.
