title: Current evidence and the evolving role of sunitinib in the management of renal cell carcinoma.
abstract: The development of targeted agents has expanded the anticancer arsenal available to oncologists and revolutionized the field of cancer treatment. In patients with advanced renal cell carcinoma (RCC), small molecule targeted therapies have improved clinical outcomes compared with cytokine-based treatments. Sunitinib malate is one such drug that has demonstrated clinical efficacy in patients with metastatic renal cell carcinoma (mRCC). This oral, multi-targeted tyrosine kinase inhibitor is approved for use in multiple countries for the treatment of advanced RCC and gastrointestinal stromal tumor patients who have progressed on imatinib therapy. In patients with advanced RCC, sunitinib significantly improves clinical outcomes with a favorable safety profile compared with conventional treatment with interferon-a. The clinically proven treatment and safety outcomes have led investigators to evaluate the merits of sunitinib therapy in the adjuvant and neoadjuvant setting in patients with mRCC. In the neoadjuvant setting, preliminary data suggest that sunitinib can effectively reduce the primary tumor and facilitate surgical resection in patients with locally advanced and mRCC. Post-operative complications were observed in some patients, but the overall safety profile and efficacy suggests that mRCC patients with surgically inoperable tumors may benefit from neoadjuvant sunitinib therapy. Ongoing clinical trials should provide insight into the value of sunitinib as adjuvant therapy.
