Successful Treatment of T4 Renal Cell Carcinoma After a Neoadjuvant Targeted Therapy Using Sunitinib: Report of a Case

Abstract

Since the introduction of targeted therapy, treatment of metastatic renal cell carcinoma (RCC) has undergone dramatic changes. Responses to targeted therapy within the primary tumor and metastatic lesions are novel findings not seen with immunotherapeutic-based strategies. We report here a case of T4 RCC in which cytoreductive nephrectomy became possible after a neoadjuvant targeted therapy using sunitinib. Our experience with the present case suggests that targeted therapy in the neoadjuvant setting may have a variety of potential applications. Further investigations should be encouraged.
