This study involves Stereotactic Body Radiation Therapy (SBRT) followed by prostatectomy (removal of the prostate). SBRT is a relatively new radiation technique in which a few doses of radiation are delivered to small, well-defined tumors. It has been used effectively in other cancers like lung and liver. The radiation will be given for only 5 days.
The purpose of this study is to compare the effects, good and/or bad, of different doses of SBRT given before prostatectomy.

Experimental: Stereotactic Body Radiation Therapy, followed by Prostatectomy
Patients will receive 6 Gy per day of Stereotactic Body Radiation Therapy (SBRT) per day for 5 days, followed by prostatectomy in 3 weeks.
Device: Stereotactic Body Radiation Therapy (SBRT)
- Measure of PSA (Prostate Specific Antigen) [ Time Frame: Up to 12 months ]Measure of PSA through treatment. PSA is expected to be undetectable (<0.2 mg/ml) after prostatectomy and radiation therapy.
- Number of symptomatic adverse anastomotic events [ Time Frame: Up to 12 months ]Number of symptomatic anastomotic events related to pre-operative SBRT.
- Mean Catheterization Time [ Time Frame: Up to 4 weeks post surgery ]Average time of catheterization following prostatectomy
- Mean Hospital Stay [ Time Frame: Up to 2 week post surgery ]Average time of hospitalization after prostatectomy
- Quality of Life assessment [ Time Frame: Baseline, at 2 weeks, 4 weeks, 2 months and every 3 months up to 12 months post surgery ]Quality of Life will be assessed using 2 questionnaires: International Prostate Symptom Score (IPSS) and Sexual Health Inventory for Men (SHIM). The IPSS is an eight question questionnaire of symptoms ranging from 0 "not at all" to 5 "always". The SHIM is a five question questionnaire ranging from 1 "almost never or never" to 5 "almost always or always" to determine erectile dysfunction.
