Brief Summary
This purpose of this study is to evaluate the safety and effectiveness of a technique called focal high-dose-rate (HDR) brachytherapy as treatment for prostate cancer that has come back in the prostate after prior radiotherapy. The study will examine the safety and efficacy of the treatment. The type of radiation that participants in this research will receive is targeted directly at the areas of the prostate where recurrent disease is evident, while avoiding treatment of the normal appearing prostate. This involves the placement of a radioactive material in the affected area of the prostate temporarily, where it remains for a short period of time, and then is subsequently removed using a minimally invasive technique called HDR Brachytherapy.

Eligibility Criteria
You may qualify if:
- Biopsy proven locally recurrent adenocarcinoma of the prostate after the completion of definitive radiation therapy for initially diagnosed prostate cancer.
- Biopsy must be performed within 182 days of trial registration
- Biopsy should be a standard sextant biopsy AND either a targeted MR/ultrasound guided biopsy or saturation biopsy or both.
- Initial cancer diagnosis that fits these specific criteria:
- Stages T1-T3a
- Nx or N0
- Mx or M0
- Eligible initial definitive radiotherapy modalities include:
- External beam radiotherapy, with photon or proton beam therapy
- Conventional or moderately hypofractionated radiotherapy
- Extremely hypofractionated external beam radiotherapy (Stereotactic body radiation therapy)
- Definitive Brachytherapy:
- Low-dose rate
- High-dose rate
- Locally recurrent disease confined to the prostate +/- seminal vesicles and immediately adjacent tissue, as evaluated by the following:
- +9 more criteria
You may not qualify if:
- Preregistration GI or GU toxicity (for any reason) grade ≥ 3 as defined in CTCAE version 4.03. That is, grade ≥ 3 GU or GI toxicity after first course of radiotherapy
- Patients receiving any other investigational agents.
- Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, severely symptomatic congestive heart failure, cardiac arrhythmia, recent myocardial infarction in last 6 months, or psychiatric illness/social situations that could limit compliance with study requirements.
- Patients who have received chemotherapy or immunotherapy within one month prior to study enrollment, other than ADT
