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

EXPERIMENTAL

Group 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.

Device: Endorectal BalloonRadiation: Radiation therapy

Rectal spacer - Radiation therapy

EXPERIMENTAL

Group 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.
