  • Clinical stages T1-T2c N0 M0 as staged by the treating investigator. (AJCC Criteria 7th Ed.- appendix III).
  • Histological evaluation of prostate biopsy with assignment of a Gleason score to the biopsy material; Gleason score must be in the range of 2-7. \> 6 cores are strongly recommended.
  • PSA values \< = 20 ng/ml within 90 days prior to randomization. Obtained prior to biopsy or at least 21 days after prostate biopsy.
  • ECOG performance status 0-1 (appendix II) assessed within 90 days of randomization.
  • Patients must sign IRB approved study specific informed consent.

  • Patients must be able to start treatment within 56 days of randomization.
  • Patients must be at least 18 years old.
  • For brachytherapy, an IPSS ≤ 21, or ≤ 17 if patient is on medications to improve urination.
  • For brachytherapy, prostate volume must be less than 55cc prior to AS.

Exclusion

  • Pelvic lymph nodes \> 1.5 cm in greatest dimension unless the enlarged lymph node is biopsied and negative.
  • Previous prostate cancer surgery to include: prostatectomy, hyperthermia and cryosurgery.
  • Previous pelvic radiation for prostate cancer.

  • Prior systemic chemotherapy for prostate cancer.
  • History of proximal urethral stricture requiring dilatation.
  • Current and continuing anticoagulation with warfarin sodium (Coumadin), heparin, low- molecular weight heparin, Clopidogrel bisulfate (Plavix), or equivalent (unless it can be stopped to manage treatment related toxicity or to have a biopsy if needed).
  • Major medical, addictive or psychiatric illness which in the investigator's opinion, will prevent the consent process, completion of the treatment and/or interfere with follow-up. (Consent by legal authorized representative is not permitted for this study).
  • Evidence of any other cancer within the past 5 years and \< 50% probability of a 5 year survival. (Prior or concurrent diagnosis of basal cell or non-invasive squamous cell cancer of the skin is allowed).
