Reducing prostate cancer treatment from 5 to 3 doses of radiotherapy
Official title: The PRECISION Study: A Phase II Study of 3 Fractions of Prostate SBRT With RayPilot System and HypoCath Image Guidance for Men With NCCN Low or Intermediate Risk Prostate Cancer
Run by NHS Lothian · NCT06117059 · Data updated 2026-11-12
This study is testing whether giving fewer doses of radiotherapy for early prostate cancer can still be just as effective and have fewer side effects for patients.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include men with low to favorable intermediate risk localized prostate cancer who meet specific health criteria.
✕Probably not a fit
Patients with advanced prostate cancer or those with certain health conditions that complicate treatment may not benefit from this study.

What this trial studies
This study investigates the feasibility of reducing the number of curative radiotherapy doses for localized early prostate cancer from 5 to just 3, using Stereotactic Body Radiotherapy (SBRT). The aim is to ensure that the side effects of this 3-dose treatment are comparable to or lower than those observed in the 5-dose treatment from the UK PACE-B trial. Utilizing the RayPilot HypoCath tumor tracking system, which continuously monitors the prostate's position during treatment, the study seeks to enhance patient experience by minimizing treatment duration while maintaining efficacy. The study is a single-arm Phase II trial conducted at centers equipped with this advanced tracking technology.
Why it matters
Potential benefit: If successful, this approach could significantly reduce the treatment burden for patients with localized prostate cancer while maintaining or improving quality of life.
How similar studies have gone: Previous studies have shown success with similar approaches to reducing treatment doses in prostate cancer, indicating potential for this method as well.
