[Current status in molecular-targeted therapy and IFNα for renal cell carcinoma in Japan].

: It has been two years since molecular-targeted therapy became available for advanced renal cell carcinoma (RCC) in Japan. It shall be validated whether molecular-targeted therapy really improved the prognosis of patients with advanced RCC in the near future. Here we review the two phase III clinical studies that demonstrated the superiority of sunitinib and temsirolimus over IFNα and discuss optimal therapy including IFNα for advanced RCC in the future biomarker era.
