No-Marker tumor tracking could make lung cancer radiation safer
NCT ID NCT04310891
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new X-ray technique to track lung tumors during radiation without needing implanted markers. Five adults with early-stage lung cancer will be observed to see if the markerless method matches the standard marker-based tracking within 3 millimeters. If it works, it could make radiotherapy less invasive and more comfortable.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Markerless Tumour Tracking (intrafraction kilovoltage X-ray imaging)
What this could lead to
If successful, this could make lung cancer radiotherapy more accurate and less invasive by removing the need for implanted markers.
What could go wrong
This is a very small, early-phase study with only 5 participants, so results may not apply to all patients. The tracking method may not be accurate enough for routine use.
