First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at whether combining a PET scan with an endoscopic ultrasound-guided needle biopsy can accurately diagnose suspicious lymph nodes in the chest. Researchers tested this less invasive approach in 75 patients who had abnormal lymph nodes on PET scans. The goal was to see if this method could replace more invasive surgical biopsies and help guide treatment decisions.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Endoscopic ultrasound-guided needle biopsy (EUS-guided puncture)
- What this could lead to
- If successful, this approach could provide a less invasive way to diagnose cancer in chest lymph nodes, reducing the need for more risky surgical biopsies.
- What could go wrong
- This is a small, early feasibility study with only 75 participants, so results may not apply to everyone. The technique may not be accurate enough to replace standard methods, and there is a small risk of complications from the biopsy.
