Phase II Trial of Transdermal Estradiol for Hormone Refractory Prostate Cancer

Multiple trials have shown the efficacy of estrogen therapy in metastatic prostate cancer, and most recently trials have supported the use of transdermal estrogens (patch) in the patient population with a decreased risk of cardiovascular disease as compared to the oral estrogens. We plan to study the use of transdermal estrogen at a dose of 0.4mg qd. We will evaluate the toxicities and measure quality of life. We will assess PSA response and measurable disease response. This will be a trial available to the Cancer Institute of New Jersey Oncology Group. We will enroll a total of 33 patients. We will plan to enroll 10 at CINJ.Patients will wear the patches (4) continuously. We will obtain blood work and clinic evaluations every three weeks. We will assess quality of life through a questionnaire given to patient every three weeks.
