Study Summary

This trial is testing whether using a needle-based laser to get real-time images of tissue during a bronchoscopy, along with the dye fluorescein, is better than just using the bronchoscopy alone for diagnosing lung cancer in patients with peripheral pulmonary nodules.

Who is the study for?
This trial is for adults over 21 who suspect they have lung cancer with nodules sized between 8-30mm on a CT scan. They must understand and sign consent forms, not be pregnant or breastfeeding, and can't have used beta-blockers or certain anticoagulants recently. Those allergic to fluorescein or unable to tolerate general anesthesia are excluded.Check my eligibility
What is being tested?
The study tests if using needle-based confocal laser endomicroscopy (nCLE) with an imaging agent called fluorescein alongside standard EBUS TBNA improves lung cancer diagnosis in patients with peripheral pulmonary nodules compared to just EBUS TBNA.See study design
What are the potential side effects?
Potential side effects may include allergic reactions to fluorescein, complications from the bronchoscopic procedure like bleeding or infection, and issues related to general anesthesia such as nausea or breathing difficulties.
