Moderate Dose Diethylstilbestrol Diphosphate Therapy in Hormone Refractory Prostate Cancer

Abstract

Objective: To examine the efficacy and toxicity of a moderate dose (250 mg/day) of diethylstilbestrol diphosphate (DES-DP) intravenously administered to patients with hormone refractory prostate cancer (HRPC) as well as the influence of this agent on the endocrine system. Patients and methods: Sixteen patients with HRPC were treated with a daily intravenous injection of 250 mg of DES-DP for 28 days. Eastern Cooperation Oncology Group (ECOG) performance status and pain score were used for subjective evaluation and PSA was used for objective evaluation. Testosterone, free testosterone, dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEA-S) were used for hormonal parameters. Results:
