This study is designed to collect saliva and blood samples from subjects going through the Lung Cancer Screening Program to compare biomarker test results to develop lung cancer clinical risk prediction models further. Also, this study will store blood samples in a biorepository.

This collaborative study was developed by the Lung Cancer Mutation Consortium (LCMC) and supported by the Thoracic Surgery Oncology Group (TSOG). The purpose of this study is to determine if it is possible to identify genetic changes in the tumors or blood of patients with early-stage lung cancers using both blood-based and tumor-based testing when cancer is suspected or first diagnosed. In this trial, participants will be asked to provide blood samples at three different time points. They will also be asked for permission for tumor tissue to be sent to the researchers. Tumor tissue will be collected if there is a leftover sample from a participant's surgery. These samples will be sent to the researchers to be analyzed for genetic changes. The researchers hope that in the future, genetic changes can help doctors determine what the best treatment is for patients with early-stage lung cancer.

The purpose of this study is to create a de-identified, public use,
repository of data of Chronic Obstructive Pulmonary Disease (COPD)
patients with by Alpha-1 antitrypsin deficiency (AATD), a rare genetic
condition that can cause COPD and emphysema.

The purpose of this study is to collect blood samples to determine if a blood-based test can be used to identify lung cancers that may or may not also be seen on images of lungs. Additionally, the study aims to see if a blood-based test can identify other types of cancers and health conditions.

A main focus of the study is to identify characteristics that can be changed such as smoking, vaping and diet, environmental exposures (e.g. pollution such as car exhaust, allergies such as pet dander) that affect lung function and risk of future lung disease. We also are looking for biomarkers (e.g. measurements of specific substances in nose, blood, and urine samples) and genetic markers that can provide us with information about lung health. The findings in this study are considered research and are not the same as "genetic testing."
