[Angiogenesis inhibition: review of the activity of sorafenib, sunitinib and bevacizumab].

Renal cell carcinoma accounts for approximately 3% of all human malignancies. The use of cytokines in metastatic stage of disease has been the standard until last decades, presenting partial and short duration responses. Research on angiogenesis in renal carcinoma has brought important advances to understand tumor biology and to allow us development of new antiangiogenic drugs. Sunitinib (SUTENT), sorafenib (NEXAVAR) and bevacizumab (AVASTIN) are actually three molecules accepted to use in metastatic renal cell carcinoma (mRCC), with a good tolerability demonstrated in different studies. Clinical evidence shows sunitinib to be reference standard of care for the first-line treatment of mRCC. The use of bevacizumab in combination with interferon alfa (IFN alfa) can also be considered in this setting. Sorafenib is recommended for second-line treatment in cytokine-refractory patients, sunitinib being also accepted in this situation. Other combination of these molecules and their use as neo-adjuvant and adjuvant therapy is being evaluated and should change in the short term the management of the disease.
