Outline Patients receive neoadjuvant therapy comprising leuprolide acetate intramuscularly for 3 months and oral bicalutamide once daily for 30 days, beginning on the first day of leuprolide acetate administration. Patients then undergo interstitial brachytherapy implantation with I-125. Following brachytherapy, patients receive adjuvant leuprolide acetate every 3 months for an additional 6 months. Quality of life is assessed at baseline and at every treatment and follow-up visit. After completion of study therapy, patients are followed every 3 months for 2 years, every to 4-6 months for 3 years, and then annually thereafter.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
