New radiation regimen aims to cut prostate cancer treatment time
NCT ID NCT00809991
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This Phase 2 study tested a radiation therapy plan that gives a slightly higher dose each day over fewer sessions (16 days instead of the usual 8-9 weeks) for men with early-stage prostate cancer. The goal was to see if this shorter schedule is safe and effective, while also tracking quality of life and side effects. 91 men with low-risk prostate cancer participated, and researchers measured urinary, bowel, and sexual function over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- radiation therapy (hypofractionated, image-guided)
- What this could lead to
- If successful, this could offer a more convenient and equally effective radiation schedule for men with early-stage prostate cancer.
- What could go wrong
- This is a small Phase 2 study, so results may not apply to all patients. The higher daily dose could increase side effects like urinary or bowel issues.

Inclusion Criteria: * Histologically confirmed, locally confined adenocarcinoma of the prostate * Clinical stages T1a to T2b PSA of less than 10 ng per ml * Gleason score of less than 3+4=7 * The patient has decided to undergo external beam radiation as treatment choice for his prostate cancer * Signed study-specific consent form prior to registration Exclusion Criteria: * Stage T3 to 4 disease * Gleason 4+3=7 or higher score * PSA greater than 10 ng per ml * Clinical or Pathological Lymph node involvement N1 * Evidence of distant metastases M1 * Radical surgery for carcinoma of the prostate * Previous Chemotherapy or pelvic radiation therapy * Previous or concurrent cancers other than basal or squamous cell skin cancers or superficial bladder cancer unless disease free for at least 5 years * History of inflammatory bowel disease * Major medical or psychiatric illness which, in the investigator's opinion, would prevent completion of treatment and would interfere with follow up
