Outcome Measures
Primary Outcomes (1)
Acute and Late Genitourinary and Lower Gastrointestinal Toxicity Using the Radiation Therapy Oncology Group Acute and Late Morbidity Scales.
Acute and late genitourinary and lower gastrointestinal toxicity will be evaluated using the Radiation Therapy Oncology Group Acute and Late Morbidity Scales, which range from 0-5, where a high score corresponds to a worse outcome/worse toxicity. Toxicity will be measured weekly during radiation, and every 6-12 months following radiation through patient interview. The acute toxicity score will be defined as the highest score obtained from measurements taken during radiation for each participant. The late toxicity score will be defined as the highest score obtained from measurements taken following completion of radiation for each participant.
Assessed weekly during radiation (from day 1 up to 3 weeks) for acute toxicity, and every 6-12 months following completion of radiation (from 3 weeks up to 84 months) for late toxicity.

Eligibility Criteria
You may qualify if:
- Male with any age (typically 50 to 70 years old) with a low risk disease. This is defined as a Gleason's score of 6 or less, clinical stage of T2a or less, and a PSA of less than 15. We will also include patients with Gleason's score of 3+4=7 if there are fewer than 2 cores positive, with no more than 5mm of tumor in aggregate dimension.
You may not qualify if:
- Prior surgery or radiotherapy for prostate cancer, PSA over 10, Gleason scores 7, 8, 9, or 10 (except Gleason 7 as noted, above), or clinical stage T2b, T2c, T3, or T4.
