Plain-language summary
This is a prospective observational study that will follow patients who undergo lung cancer screening at the San Francisco VA Medical Center, University of California, San Francisco (UCSF) Medical Center, and the San Francisco General Hospital. The proposed study will comprise of two primary populations to determine the ctDNA assay performance in a variety of clinical settings.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age ≥ 40 years
* Ability to understand and provide written informed consent
* Willingness to comply with study protocols and provide blood samples.
* Willingness to complete 3-year clinical follow up
Exclusion Criteria:
* Active non-cutaneous malignancy within the past 5 years as per medical record or patient report.
* Exclusion criteria for possible follow-up visit blood draw:
* Anemia - measured by hematocrit level of less than 30%, measured after the first blood draw.
* Malnourishment - determined by BMI less than 19. If subject has BMI greater or equal to 19, but has a history of malnourishment, study staff will measure albumin level of subject's blood after initial blood draw. Albumin level must be greater than 2.5 mg per deciliter, or subject will be excluded.
* Severe Chronic Obstructive Pulmonary Disease (COPD) - defined by Gold Stage IV.
* Unstable heart conditions - defined by stable or unstable angina, recent myocardial infarction (within the last 2 years), active congestive heart failure, ischemic cardiomyopathy, or history of complications because of previous blood donation.
* Liver cirrhosis.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
