Abstract

Target agents such as tyrosine kinase inhibitors have improved renal cell carcinoma (RCC) patient outcomes. However, complete remission (CR) with target agents is rare. Furthermore, CR of bone metastasis is much less common. We report a case of CR in bone and lung metastatic RCC. Radical nephrectomy was performed first, and clear cell RCC was diagnosed. Thereafter, sunitinib was started, and bone and lung metastases resolved entirely after 8 months of treatment. Sunitinib therapy was discontinued after 2 years because of the adverse event of proteinuria. However, the patient has remained in CR for over 1 year after sunitinib cessation.
