  Purpose

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.

Primary Outcome Measures:
  • Comparison of PSA levels and biopsy results at 36 months [ Designated as safety issue: No ]

Estimated Enrollment: 420
Study Start Date: April 2008
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

  • 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.
