Adjuvant therapy in renal cell carcinoma in the immunotherapy era: where do we stand?

Abstract

Locoregional, as well as metastatic renal cell carcinoma, tends to relapse after nephrectomy or metastasectomy. Adjuvant therapy seems to be aneffective strategy to reduce the risk of recurrence. Allanti-VEGF tyrosine kinase inhibitorsexcept sunitinib have failedto show any benefit in the adjuvant setting in patients with locally advanced disease and an intermediate-to-high chance of recurrence. On the other hand, immune checkpoint inhibitors, which are now used in the first-line in the metastatic setting, are being tested in the adjuvant setting. Pembrolizumab has shown benefit in the adjuvant setting in patients with a high risk of recurrence or with resected metastatic disease with no evidence of disease. Results for other checkpoint inhibitors are still awaited.
