Salvage Therapy with Bevacizumab-Sunitinib Combination after Failure of Sunitinib Alone for Metastatic Renal Cell Carcinoma: A Case Series

We present a case series of seven patients with metastatic renal cell carcinoma treated with bevacizumab (10 mg/kg) in combination with sunitinib 25-50 mg as salvage therapy after disease progression under sunitinib monotherapy. Two patients had a partial response, four had stable disease, and one patient had disease progression. After a median follow-up of 17.2 mo, median progression-free survival and overall survival were 8.5 and 15.1 mo, respectively. Two patients experienced exacerbation of their preexisting hypertension; there were no grade 4 toxicities. The bevacizumab-sunitinib combination in sunitinib-refractory patients seems active and has a tolerable toxicity profile.
