Glowing dye could help lung cancer patients keep more healthy lung tissue
NCT ID NCT02570815
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a dye called indocyanine green (ICG) can help surgeons see the exact boundary of a lung cancer tumor during robotic surgery. The dye makes the healthy lung glow, leaving the cancerous segment dark. The surgeon then removes only that dark segment, sparing more healthy tissue. The trial involves 250 adults with early-stage non-small cell lung cancer and aims to see if this technique is accurate and safe.
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 (ICG) dye
- What this could lead to
- If successful, this technique could allow more patients with early lung cancer to have a smaller, lung-sparing surgery instead of removing an entire lobe.
- What could go wrong
- This is an early Phase 1 trial focused on feasibility, not yet on long-term outcomes. The dye may cause allergic reactions, and the approach may not work for all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age \> 18 years 2. Tumor size \<3 cm 3. Clinical Stage 1 Non-Small Cell Lung Cancer (NSCLC) 4. CT-imaging confirming that the tumour is confined to the one broncho-pulmonary segment, rendering the patient a candidate for segmental resection. Exclusion Criteria: 1.
