Complete Histologic Remission after Sunitinib Neoadjuvant Therapy in T3b Renal Cell Carcinoma

The authors present the first case report of complete histologic remission after neoadjuvant sunitinib treatment on primary renal tumour and vena cava thrombus. A 78-yr-old woman with an Eastern Cooperative Oncology Group (ECOG) score of 0 presented with a T3b renal tumour. She refused surgical treatment but agreed to percutaneous biopsy and medical treatment. A Fuhrman III renal cell carcinoma was histologically confirmed on percutaneous biopsy, and sunitinib treatment was administered over 6 mo. A significant objective response was observed for tumour size and thrombus. The patient finally accepted surgical treatment. Pathologic examination concluded with a complete response of primary tumour and thrombus. (C) 2008 European Association of Urology. Published by Elsevier B.V. All rights reserved.
