New imaging technique could help doctors predict cancer treatment response
NCT ID NCT01235052
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a PET scan using a tracer called FMISO can measure oxygen levels (hypoxia) in head and neck cancers. Sixteen patients received the scan before starting radiotherapy. The goal was to see if the amount of hypoxia seen on the scan could predict how well the cancer responded two years later. The results were not used to change treatment, but to see if this imaging method could be useful in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-FMISO (a radioactive tracer used in PET scans)
- What this could lead to
- If successful, this could help doctors better predict how head and neck cancers will respond to radiotherapy, potentially guiding more personalized treatment plans.
- What could go wrong
- This was a very small study (16 people) and only looked at whether the scan could predict outcomes—it did not test a new treatment. The results may not apply to all patients.
