PSA Levels and Biopsy Samples After Implant Radiation and Hormone Therapy in Patients With Stage I or Stage II Prostate Cancer
RATIONALE: Studying samples of blood and tissue from patients with prostate cancer after receiving implant radiation therapy and luteinizing hormone-releasing hormone agonist may help doctors identify biomarkers related to cancer and help doctors predict how patients will respond to treatment.
PURPOSE: This laboratory study is looking at PSA levels and biopsy samples after undergoing implant radiation therapy and luteinizing hormone-releasing hormone agonist therapy in patients with stage I or stage II prostate cancer.
|Official Title:||Analysis of Biopsy Results at 36 Months After Permanent I-125 Implantation Therapy Plus LHRH-agonist Therapy for Patients With Untreated Intermediate Prostate Cancer.|
- Comparison of PSA levels and biopsy results at 36 months [ Designated as safety issue: No ]
|Study Start Date:||April 2008|
|Estimated Primary Completion Date:||September 2014 (Final data collection date for primary outcome measure)|
- To analyze biopsy results at 36 months after permanent iodine I 125 implantation therapy and luteinizing hormone-releasing hormone (LHRH) agonist therapy for patients with untreated intermediate-risk prostate cancer.
OUTLINE: Patients received luteinizing hormone releasing-hormone (LHRH) agonist therapy and permanent iodine I 125 implantation on protocol JUSMH-BRI-GU05-01.
Patients undergo blood sample collection and tissue biopsy for biomarker/laboratory analysis at 36 months after receiving brachytherapy and releasing-hormone agonist therapy. PSA levels and biopsy results are compared.
