The aim of this study was to evaluate the use of sunitinib as third-line therapy for metastatic renal cell carcinoma (mRCC). This study included a total of 35 consecutive Japanese patients with mRCC who were treated with third-line sunitinib after sequential use of cytokine therapy (interferon-alpha and/or interleukin-2) and sorafenib between September 2008 and December 2010. The clinical outcomes of third-line sunitinib in these patients were retrospectively reviewed. Of the 35 patients, 3 (8.6%), 28 (80.0%) and 4 (11.4%) were judged to have a partial response, stable disease and progressive disease, respectively, as the best response to sunitinib. The median progression-free survival (PFS) and overall survival (OS) of these patients following the introduction of sunitinib were 10.9 and 14.2 months, respectively. Of several factors examined, response to sorafenib and performance status appeared to be independently associated with PFS and OS, respectively, on multivariate analyses. The common grade 3-4 adverse events related to third-line sunitinib were thrombocytopenia (51.4%), neutropenia (42.9%) and hypertension (14.3%). Despite the low response rate, third-line sunitinib is well tolerated and could provide comparatively favorable prognostic outcomes in Japanese patients with mRCC after first-line cytokine therapy and second-line sorafenib; therefore, treatment with sunitinib could be one on the therapeutic options for patients with mRCC even after the failure of sequentially performed systemic therapies, such as cytokine therapy and sorafenib.
