We evaluated this combination in 25 patients with progressive hormone refractory prostate cancer. Of 24 patients with an elevated prostate specific antigen (PSA) level at the start of treatment 13 (54%, 95% confidence limits 34 to 74%) had a greater than 50% decrease in PSA levels on at least 3 consecutive biweekly determinations. The median decrease in PSA in responding patients was 64% (mean 71.7%) and the median duration of response was 7 months. In 5 patients with bidimensionally measurable disease 2 partial responses were observed. Treatment was well tolerated, with mild and manageable toxicity. This is a well tolerated outpatient treatment regimen for patients with hormone-refractory prostatic cancer which deserves further investigation. © 1992 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited ByScher H and Kelly W (2018) Editorial: States and State Transitions are All That Really MatterJournal of Urology, VOL. 168, NO. 6, (2451-2453), Online publication date: 1-Dec-2002.OH W and KANTOFF P (2018) MANAGEMENT OF HORMONE REFRACTORY PROSTATE CANCER: CURRENT STANDARDS AND FUTURE PROSPECTSJournal of Urology, VOL. 160, NO. 4, (1220-1229), Online publication date: 1-Oct-1998.Joyce R, Fenton M, Rode P, Constantine M, Gaynes L, Kolvenbag G, DeWolf W, Balk S, Taplin M and Bubley G (2018) HIGH DOSE BICALUTAMIDE FOR ANDROGEN INDEPENDENT PROSTATE CANCER: EFFECT OF PRIOR HORMONAL THERAPYJournal of Urology, VOL. 159, NO. 1, (149-153), Online publication date: 1-Jan-1998.Hartley-Asap B, Vukanovic J, Joseph I, Strandgarden K, Polacek J and Isaacs J (2018) Anti-Angiogenic Treatment with Linomide as Adjuvant to Surgical Castration in Experimental Prostate CancerJournal of Urology, VOL. 158, NO. 3, (902-907), Online publication date: 1-Sep-1997.Iversen P, Rasmussen F, Asmussen C, Christensen I, Eickhoff J, Klarskov P, Larsen E, Mogensen P, Mommsen S and Rosenkilde P (2018) Estramustine Phosphate Versus Placebo as Second Line Treatment After Orchiectomy in Patients With Metastatic Prostate Cancer: Daproca Study 9002Journal of Urology, VOL. 157, NO. 3, (929-934), Online publication date: 1-Mar-1997.Cox R and Crawford E (2018) Estrogens in the Treatment of Prostate CancerJournal of Urology, VOL. 154, NO. 6, (1991-1998), Online publication date: 1-Dec-1995.
