Brief Summary
RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. PURPOSE: This clinical trial is studying how well proton radiation therapy works in treating patients with prostate cancer.

Outcome Measures
Primary Outcomes (2)
As a feasibility precaution patients will be treated and followed for a minimum of 60 days after completion of radiotherapy to determine feasibility
5 years
Acute toxicity as assessed by NCI CTC Version 3.0
90 days
Secondary Outcomes (2)
Late toxicity as assessed by RTOG/EORTC late morbidity scoring system
90 days
Biochemical/clinical progression-free survival
Time from start of radiotherapy to either documented increase in PSA or clinical progression of disease, death due to any cause or last patient contact alive
Study Arms (1)
Arm I
EXPERIMENTALPatients undergo proton radiotherapy once daily 5 days a week for approximately 9 weeks in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- Histologically confirmed prostate adenocarcinoma within 365 days of registration
- Clinical stages T1a-T2a N0 M0
- For any pelvic lymph node \>= 1.5cm, biopsy of the lymph node is mandatory
- PSA values \< 10 ng/ml within 90 days prior to registration, done either prior to prostate biopsy or at least 21 days after prostate biopsy.
- Alkaline phosphatase within 60 days prior to registration. If alkaline phosphatase is elevated \> 2 x the upper limit of institutional normal (UNL), patient must have radiological correlation to assess for metastases
- Zubrod status 0-1 documented within 60 days of registration
- Prior androgen deprivation is allowed; however, androgen deprivation will not be continued concurrently or as an adjuvant therapy
- Patients must give IRB-approved study-specific informed consent
- Patients must complete all required tests listed within the specified time frames
- Patients must be able to start treatment within 56 days of registration
- Members of all races and ethnic groups are eligible for this trial
You may not qualify if:
- Clinical stages T2c or greater
- PSA of 10 ng/ml or greater
- Gleason score 7 or higher
- Evidence of distant metastasis
- Evidence of lymph node involvement
- Previous prostate cancer surgery to include: prostatectomy, hyperthermia and cryosurgery
- Previous pelvic radiation for prostate cancer
- Androgen deprivation therapy prior to radiation is allowed; however, it is not acceptable if continued during radiation or as adjuvant therapy
- Active rectal diverticulitis, Crohn's disease, or ulcerative colitis are not allowed
- Prior systemic chemotherapy for prostate cancer
- History of proximal urethral stricture requiring dilatation
