Brief Summary:
Optimal non surgical treatment of prostate cancer requires dose escalation which is frequently provided by adding a brachytherapy "boost" to a short course of external beam radiotherapy. The hypothesis in this randomized study is that a High Dose Rate (HDR) brachytherapy boost leads to equivalent or better Prostate Specific Antigen (PSA) recurrence-free survival when compared to a Low Dose Rate (LDR) brachytherapy boost and that it is associated with a more favorable toxicity profile and improved quality of life.

Condition or disease Intervention/treatment Phase
Prostate Cancer Radiation: HDR Radiation: LDR Not Applicable

Detailed Description:
Men with intermediate or high risk prostate cancer who are technically suitable for prostate brachytherapy based on prostate size and voiding function and who are interested in this modality of treatment will be approached for randomization between either high dose rate (single 15 Gray) or low dose rate permanent seed implant (110 Gray) brachytherapy. Baseline International Prostate Symptom score, Quality of Life Assessment and International Index of Erectile Function will be recorded and then every 3 months for the first year and every 6 months to 3 years. Androgen deprivation treatment is allowed for 6 or 12 months.

Arm Intervention/treatment
Active Comparator: LDR boost
After completion of 46 Gy of external beam radiotherapy subjects will undergo a permanent seed radioactive implant to the prostate using iodine-125 seeds to deliver a dose of 110 Gy
Radiation: LDR
Low dose rate brachytherapy boost

Active Comparator: HDR boost
Subjects in this arm will undergo an HDR implant to deliver 15 Gy to the prostate prior to commencing the external beam component of their treatment.
Radiation: HDR
High dose rate brachytherapy

Primary Outcome Measures :
  1. Quality of Life [ Time Frame: 6 months ]
    Quality of life will be measured through validated instruments including International Prostate Symptom Score, the International Index of Erectile Function, and the urinary, bowel and sexual domains of EPIC

Secondary Outcome Measures :
  1. Quality of Life long term [ Time Frame: 3 years ]
    Quality of Life will be assessed to 3 years using the validated instruments International Prostate Symptom Score, International Index Erectile Function and EPIC

Other Outcome Measures:
  1. Efficacy [ Time Frame: 8 years ]
    regular PSA monitoring every 6 months to 3 years and then annually to determine PSA recurrence free survival
