This trial is a prospective, single-arm, multi-center clinical trial designed to assess whether adaptive radiotherapy with urethral sparing for low to intermediate risk localized prostate cancer will translate into a decreased rate of patient reported acute urinary side effects, as measured by the patient reported EPIC-26 questionnaire, compared with the historically reported rate for non-adaptive, non-urethral sparing prostate SBRT.
Inclusion Criteria: 1. Patient has NCCN low or intermediate risk prostate cancer that is biopsy proven. 2. Prostate volume is ≤80cc as assessed by MRI prior to radiotherapy. 3. AUA/IPSS score is ≤ 15. 4. ECOG performance status is ≤2 (or Karnofsky score is ≥60%). 5. Patient has no PIRADS 4 or 5 lesion on prostate MRI contacting the urethra (determined at physician discretion). 6. Patient has the ability to complete required patient questionnaires. 7. Patient age ≥ 18 years (or greater than the local age of majority). 8. Patient has the ability to understand and the willingness to sign a writt…
The radiation plan for each daily fraction is adapted from the initial plan based on cone beam CT imaging acquired while the participant is laying on the treatment machine.
