Etoposide in prostate cancer

Hormone refractory prostate cancer is a disease that kills approximately 39,000 people per year. No single chemotherapeutic agent or regimen has been demonstrated to provide a survival advantage in this disease. Etoposide as a single agent, both in i.v. and oral formulations has not proven to be effective. In the 1990s, however, etoposide has been combined with several agents to create novel treatment regiments for patients with hormone refractory disease. Several of these regimens, all involving oral etoposide, have demonstrated promising results in Phase II trials and early results suggest that they may increase survival for hormone refractory patients, although this remains to be tested in a Phase III trial setting.
