Gn-RH antagonist possible response, after Gn-RH agonist failure in a man with metastatic prostate cancer

Anticancer Res. 2005 Jan-Feb;25(1B):577-8.

Abstract

Gn-RH agonists or surgical castration are considered standard treatment for patients affected by metastatic prostate cancer. Despite greater cost, chemical castration is often considered the treatment of choice as it is psychologically better tolerated. We report our experience of one patient undergoing treatment with Gn-RH agonist who developed an early resistance to the administered drug, with serum testosterone levels within the range of normality.
