Trial summary

Despite intensive research efforts, there are still no simple and effective screening tools to detect early lung cancer. The majority of newly diagnosed patients have higher stage, often disseminated, non-resectable disease. Read more about this study

About this study

Despite intensive research efforts, there are still no simple and effective screening tools to detect early lung cancer. The majority of newly diagnosed patients have higher stage, often disseminated, non-resectable disease. A better understanding of the natural biology and molecular abnormalities in early lung lesions may aid in the development of more effective screening tools. This study will investigate the effectiveness of bronchoscopy by white light (WL) alone and in combination with Lung Imaging Fluorescence Endoscopy (LIFE) for the detection of early lung lesions in patients with a high risk for developing lung cancer. LIFE is a FDA approved adjunct to WL bronchoscopy for the screening of lung cancer and this study will provide a standardized setting in which a direct comparison between a combination of WL and LIFE versus traditional WL bronchoscopy can be made.

In addition, the study will set the stage for the collection of a unique set of biopsy specimens that will be used to learn more about the natural biology and the molecular changes in early lung lesions. We will study abnormalities in p53 by immunohistochemistry and by molecular analyses. The p53 results will be compared with histological grade and with genomic instability. Measures for genomic instability will be the loss of chromosomal information and cellular aneuploidy. Recent advances in molecular pathology, such as the development of Laser Capture Microdissection (LCM), have made the molecular profiling of these extremely small lesions feasible. The information obtained by these techniques will be used for comparison with clinical and exposure information. Future plans include the culturing of bronchial epithelial cells to study genomic instability in the multistep process of cancer progression. It is our hope that the application of these new technologies will improve the early detection of human lung cancer and provide insight into the natural biology and molecular changes of early lung lesions which may progress towards overt cancers.

The majority of newly diagnosed patients have higher stage, often disseminated, non-resectable disease. A better understanding of the natural biology and molecular abnormalities in early lung lesions may aid in the development of more effective screening tools. The Lung Imaging Fluorescence Endoscopy (LIFE) is FDA approved as an adjunct to WL bronchoscopy for the screening of lung cancer.

Using the LIFE unit, this study will set the stage for the collection of a unique set of biopsy specimens that will be used to learn more about the natural biology and molecular changes in early lung lesions.

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer, run by National Institute of Environmental Health Sciences (NIEHS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Nov 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Genetic abnormalities (time frame: 6 months, 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00512642, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Nov 2019; AzTrials last refreshed its copy on 7 Nov 2026.
