The purpose of this study is to determine the effects of CyberKnife radiosurgery in patients with early stage prostate cancer.
The investigators hypothesize that hypofractionated stereotactic radiotherapy via the CyberKnife® can deliver tumor ablating doses of radiation to prostate tumors safely and effectively while sparing the adjacent tissues (rectum, bladder, ureters, urethra, penile bulb, and bowel) from receiving damaging doses of radiation.

- Local control rate [ Time Frame: 5-10 years ]
- To assess the effects of hypofractionated stereotactic radiosurgery on the long-term local tumor control of prostate cancer (through documentation of the rate of biochemical Disease-Free Survival [bDFS], Phoenix and ASTRO definitions, at 5 and 10 years).
- To document the rates of acute and late grade 3-5 gastrointestinal and genitourinary toxicity observed during the years following CyberKnife SRS for prostate cancer.
- Overall survival [ Time Frame: 5-10 years ]To measure the following in the study population: rates of local failure, distant failure, disease-free survival, disease-specific survival; quality of life (QOL) in generic and organ-specific domains.
