  Purpose
This study is based on previous observation that, in men with localized prostate cancer, non-cancerous prostate tissue is hypoxic, and on the known contribution of hypoxia to the progression of cancer. Patients undergoing diagnostic prostate biopsy with serum prostate specific antigen (PSA) less than 10ng/ml and who have given informed consent will have oxygen measurements of the prostate and peri-prostatic tissue taken with the Eppendorf electrode at the time of biopsy. The oxygenation of normal prostate tissue will be compared to that of cancerous prostate tissue. In men with negative biopsies, the prostate tissue oxygen measurements will be compared with the peri-prostatic tissue oxygen measurements.

Condition Intervention Phase
Prostatic Neoplasms Procedure: Oxygen measurement - Eppendorf machine Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Oxygenation of the Prostate Gland: a Polarographic Electrode Study in Men Undergoing Prostate Biopsy.

Secondary Outcome Measures:
  • Median pO2 and HP5 for the prostate gland in each patient with negative biopsy result will be compared with the median pO2 and HP5 for peri-prostatic tissue. [ Time Frame: 7 years ]

Estimated Enrollment: 40
Study Start Date: April 2001
Study Completion Date: March 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)
