Primary Outcome Measures:
- To Determine the Effect of Short-term Intake of Daily Dutasteride Prostate Cancer Volume, Distribution Within the Gland and Gleason Score Sum in Patients in Comparison to Placebo After Adjusting for Changes in Prostate Gland Volume. [ Time Frame: 24 Months ]The effect of Dutasteride intake on the following parameters as detected by mapping biopsy vs. initial trans-rectal biopsy in the treatment arm and the control group: change in prostate gland volume, change in distribution within the gland, and change in Gleason score sum.

| Primary Completion Date: | January 2013 (Final data collection date for primary outcome measure) |
| Arms | Assigned Interventions |
|---|---|
|
Experimental: Dutasteride
The drug, Dutasteride, will be administered at 0.5 mg dose and given everyday (QD), for 3 months.
|
Drug: Dutasteride
Dutasteride will be administered at 0.5 mg dose and it will be given every day (QD), for approximately 3 months, followed by 3D mapping biopsy.
Other Name: Avodart
|
|
Placebo Comparator: Placebo
The placebo group will receive a placebo drug for 3 months, instead of the intervention drug, Dutasteride.
|
Other: Placebo
The placebo group will receive the same standard of care as the intervention group, but instead of receiving the intervention drug, Dutasteride, participants will receive a placebo drug for the same 3 month period.

Detailed Description:
This is a study of men who have undergone a standard 10 or more core biopsy for detection of prostate cancer and determined to have prostate cancer by having a Gleason score ≤ 7 (low to moderate risk 2-7). Of these men, one arm of a two arm randomized group will be administered a treatment regime of Dutasteride versus the control group who receive standard of care, prior to mapping biopsy. This proposal aims at studying the apparent effect of the use of Dutasteride (3 months) on initial tumor volume (at diagnosis) in men with low volume cancer before undergoing 3D mapping biopsy.
