Purpose
A prostate cancer diagnosis starts a list of events that often leads to fast-moving treatment, thought by many to result in vast over-treatment of this disease. So, discovery of different diagnostic methods that allow clinicians to identify slow-growing from potentially fast-growing disease prior to or at the time of prostate biopsy could result in early and suitable treatment for men at greatest risk, while greatly decreasing the number of biopsies, surgical procedures, hormonal and chemotherapeutic treatments, cost, and patient worry, for those with more slow-growing disease.

| Official Title: | Imaging Prostatic Lipids to Distinguish Aggressive Prostate Cancer |
- Number of participants with increased intraprostatic lipid concentration [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]Determine the correlation between the amount of intraprostatic lipid using 1H magnetic resonance spectroscopic imaging (MRSI) with an endorectal coil obtained prior to prostatectomy with fatty acid synthase protein expression measured in benign and cancer tissue from prostatectomy samples.
- Number of participants with increased tumor aggressiveness [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]Identify the association between fatty acid synthase protein expression in prostatectomy samples, intraprostatic lipid as measured by 1H MRSI, and prostate tumor aggressiveness.
- Number of participants with accumulation of lipid intermediates and proteins [ Time Frame: Up to 3 years ] [ Designated as safety issue: No ]To quantify the association between key metabolic intermediates involved in lipid metabolism, mitochondrial function, inflammation, and apoptosis in prostatectomy samples and fatty acid synthase protein expression, intraprostatic lipid and tumor aggressiveness.
