Outcome Measures
Primary Outcomes (1)
Incidence of Patient-reported Acute Toxicity Based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 4
To compare acute toxicity (as defined by CTCAE v4.0) and to compare Rectal dose (V35, max rectal dose). Acute radiation toxicities are side effects that occur on treatment or in the immediate post treatment period (within 90 days from the start of radiation treatment).
Baseline to 1 year
Secondary Outcomes (4)
Measure the Effect of Treatment on Patients' Using Health Related Quality of Life Based on Expanded Prostate Cancer Index Composite Questionnaire
1 year
Number of Participants With Recurrence-free Survival
1 year
Comparing Several Parameters That Are Involved in Treatment Planning in Patients Randomized to Two Radiation Therapy Modalities.
5 years
Incidence of Patient-reported Toxicity (Late Toxicity) Based on the Common Terminology Criteria for Adverse Events (CTCAE) Version 4
post RT to 1 year
Other Outcomes (2)
Measuring Number of Participants Changes in the Microbiome That is Associated With Normal Tissue Toxicities Resulting From Radiation From Baseline to End of Treatment
baseline, post radiation follow up
Comparing Neutrophile:Lymphocyte Ratio (NLR) at Different Time Points to Assess Impact of SBRT in All the Participants
1 month, 6 months, 1 year
Study Arms (2)
Endorectal balloon - Radiation therapy
EXPERIMENTALGroup 1 : Endorectal balloon (ERB): Immobilization device manually placed into the rectum prior to radiation treatment planning CT and daily treatment delivery, to immobilize the prostate and reduce prostate motion. Patients on each arm will receive 5 fractions of radiation, 7.25Gy per fraction, delivered 2-3 times a week (every other day excluding weekends), to total dose of 36.25 Gy. The total duration of treatment will be no shorter than 10 days.
Rectal spacer - Radiation therapy
EXPERIMENTALGroup 2 : Rectal spacer (RS): Biodegradable gel that is transperineally injected between the rectum and prostate under transrectal ultrasound guidance, to increase physical distance and thereby reduce radiation dose to the anterior rectal wall. The spacer begins to biodegrade in 2-3 months, and is fully absorbed within 6 months. Patients on each arm will receive 5 fractions of radiation, 7.25Gy per fraction, delivered 2-3 times a week (every other day excluding weekends), to total dose of 36.25 Gy. The total duration of treatment will be no shorter than 10 days.

Eligibility Criteria
You may qualify if:
- Biopsy-proven diagnosis of prostate adenocarcinoma, diagnosed within 1 year of randomization
- Either NCCN-defined low-risk disease (T1c-T2a, Gleason score 3+3=6, PSA \<10), intermediate-risk disease (Gleason score 3+4=7, 4+3=7, T2b-c and/or PSA 10-20; ) or high-risk disease due to Gleason score 8-10 and/or PSA \>20 ng/ml, but not due to T3-T4 disease on physical exam.
You may not qualify if:
- History of prior pelvic radiation (external beam or brachytherapy)
- Prior or concurrent lymphomatous/hematogenous malignancy, or history of prior/concurrent invasive malignancy during the past 5 years
- Very high risk prostate cancer (T3b-T4 on clinical exam, Primary Gleason pattern 5, or \>4 cores with Gleason score 8-10)
- History of prior chemotherapy for prostate cancer
- History of irritable bowel disease
- Evidence of lymph node involvement
- AUA score \>15
- Prostate size \> 90 cc
