Wealth of Riches in RCC Treatment: How Do We Avoid 'Devaluing the Dollar'?

September 01, 2007

The treatment of metastatic renal cell carcinoma (RCC) has changed dramatically over the past few years. An improved understanding of the biology of RCC has resulted in the development of novel targeted therapeutic agents that have altered the natural history of this disease. In particular, the hypoxia-inducible factor (HIF)/vascular endothelial growth factor (VEGF) pathway and the mammalian target of rapamycin (mTOR) signal transduction pathway have been exploited. Sunitinib malate (Sutent), sorafenib tosylate (Nexavar), bevacizumab (Avastin)/interferon alfa, and temsirolimus (Torisel) have improved clinical outcomes in randomized trials by inhibiting these tumorigenic pathways. Combinations and sequences of these agents are being evaluated. Other novel multitargeted tyrosine kinase inhibitors (pazopanib and axitinib) and mTOR inhibitors (everolimus) are in clinical development. Recently reported and ongoing clinical trials will help further define the role of these agents as therapy for metastatic RCC.

Testicular Cancer: Maintaining the High Cure Rate

February 01, 2003

The management of germ cell tumors has advanced dramatically,with cure rates approaching 90% to 95%. Treatment of stage I/Aseminomas generally includes orchiectomy and adjuvant radiotherapy.Treatment of stage I/A nonseminomatous germ cell tumors involvesorchiectomy followed by retroperitoneal lymph node dissection oractive surveillance. One of the major advances has been the introductionof cisplatin-based chemotherapy for metastatic disease and thedevelopment of a system of risk attribution. The logical managementof any patient with curable disease is to provide curative therapy andthen follow the patient in a structured manner, to diagnose and treatany complications in a timely manner.
