Sporadic renal cell carcinomas are characterized by EGFR (HER-1) and EGFR-2 (HER-2) expression, however, signal transduction inhibitors of this pathway were clinically ineffective. Clear cell renal cell cancer is hormone-, irradiation- and chemotherapy resistant with moderate sensitivity to immunotherapy. The only clinically effective class of agents in case of this tumor type was proved to be the angiosuppressive agents. In 2005 FDA approved sorafenib for the first line treatment while in 2006 sunitinib for second line treatment in the cytokine resistant medium-risk renal cell carcinoma. This was followed by the European approval of both agents for second line treatment of renal cell cancer. Sunitinib was approved for first line treatment of renal cell cancer in Europe based on a phase III trial comparing it to interferon. Temsirolimus obtained its approval for the treatment of high risk renal cell cancer patients in 2007. Last but not least, FDA approval is on the way in case of bevacizumab as well to treat renal cell cancer. Based on the data demonstrated on the ASCO'2007, various modalities have to be developed for various stages of progression of clear cell renal cell cancer.
