Study Summary

This trial uses a new technology called optical biopsy to improve the accuracy of lung cancer diagnosis.

Who is the study for?
This trial is for adults with suspicious lung lesions identified on CT scans, who are already scheduled for a lung biopsy. They must consent to 2-3 extra samples for research and be able to give informed consent. It's not open to minors, prisoners, pregnant women, or those unable to consent due to language barriers or cognitive impairments.Check my eligibility
What is being tested?
The study is testing real-time optical biopsy using confocal microscopy during standard lung biopsies. The goal is to see if this technology can better diagnose lung cancer and distinguish between cancerous and non-cancerous lesions found in CT screenings.See study design
What are the potential side effects?
Since the intervention involves additional biopsy samples rather than medication, side effects may include typical risks associated with biopsies such as discomfort at the biopsy site, bleeding, infection risk, and very rarely collapsed lung.

Experimental Treatment
Group I: Diagnostic (lung biopsy)Experimental Treatment2 Interventions
Patients undergo extraction of up to 3 additional lung biopsies from target lesions that are at least 2-3 cm in diameter using the 19 gauge SuperCore biopsy needle or the 20 gauge Rotax needle. The extracted tissue is imaged via confocal fluorescence microscopy using a variety of fluorescent contrast agents, such as fluorescein sodium, methylene blue, indocyanine green and then undergo hematoxylin and eosin processing.
