Dye vs. air: which better guides lung cancer surgery?

Summary

This study compared two ways for surgeons to see the borders between lung segments during surgery for early-stage non-small cell lung cancer. One method uses a green dye and a special camera, the other uses a modified inflation-deflation technique. The trial involved 272 patients across multiple centers and measured how often each method successfully showed the segment border, as well as surgery time and blood loss. The goal is to provide evidence to help surgeons choose the best approach for precise lung-sparing surgery.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Indocyanine green dye
What this could lead to
If successful, this could help surgeons choose the best method to identify lung segment boundaries, potentially improving surgery accuracy and recovery for early-stage lung cancer patients.
What could go wrong
This is a completed trial comparing two techniques, not testing a new treatment. The results may not change practice if one method is not clearly better, and findings may not apply to all patients or hospitals.
