New PET-scan method may sharpen brachytherapy for cervical cancer
NCT ID NCT03315351
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explores whether using a PET-scan at the start of brachytherapy (internal radiation) is feasible for patients with locally advanced cervical cancer. Fourteen participants who have already received chemoradiation will undergo an extra PET-scan during brachytherapy and another four months later. The goal is to see if this approach helps doctors better define the tumor target for treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to more precise brachytherapy for cervical cancer, potentially improving tumor targeting and reducing side effects.
- What could go wrong
- This is a very small, early feasibility study with only 14 participants. It does not test whether the approach actually improves outcomes, so it may not lead to any practical change in treatment.
