Brief Summary
Radiation therapy is considered a standard treatment option for the management of localized prostate cancer. Among the 20-30% of patients who recur, there is no consensus on the optimal salvage therapy. Salvage options available for isolated local recurrence include; temporary or permanent implantation of radioactive seeds into the prostate, complete removal of the prostate gland, use of low temperatures to treat the disease (cryotherapy), and high frequency ultrasound to treat the disease. There are risks of complications associated with all these treatments, and there is presently no consensus as to which treatment is the best. The aim of this pilot study is to look at the feasibility and toxicities of whole gland salvage treatment of the prostate using temporary implantation of radioactive seeds into the prostate.

Interventions
Eligibility Criteria
You may qualify if:
- Biopsy confirmed locally recurrent prostate adenocarcinoma \> 30mths after completion of XRT by stereotactic transperineal biopsy
- Staging T2-weighted, DWI- and DCE- MRI that demonstrates recurrence confined to prostate, and correlates with stereotactic transperineal biopsy
- Previous external beam radiotherapy for prostate cancer with standard/conventional fractionation (1.8-2.0 Gy per fraction), or moderate hypofractionation (2.4-3.4 Gy per fraction).
- Staging CT or MRI (abdomen and pelvis) and bone scan are negative for metastases
- IPSS \< 15
- Baseline (post XRT) serum PSA \< 10ng/mL
- Prostate volume as measured by TRUS \< 50cc
- ECOG performance status 0-1
You may not qualify if:
- Disease adjacent to the urethra as visible on MRI
- Any of the following prior therapies; TURP, radionuclide prostate brachytherapy, prostatectomy or prostatic cryosurgery, HIFU, bilateral orchiectomy, chemotherapy for prostatic carcinoma
- Evidence of castrate resistance (defined as PSA \> 3ng/mL while testosterone is \< 1.7nmol/L) Patients could have been on combined androgen blockade with initial XRT but are excluded if this was started due to PSA progression
