LEGACY: Lung Cancer Screening in Individuals With a Lung Cancer Family History-Protocol A

This research is being done to determine if an image-based deep learning model (Sybil) can accurately predict the likelihood of future lung cancer based on chest computed tomography (CT) imaging from individuals.

This non-therapeutic study will enroll individuals who have family history of lung cancer. Participants will undergo a low-dose non-contrast computed tomography of the chest (LDCT) and may also send images from any chest CT scan(s) obtained as part of routine clinical care, outside of the study. The images and data collected will be analyzed by an image-based deep learning model (Sybil). Sybil is a type of artificial intelligence model that has been shown to accurately predict individuals' future risk of lung cancer based solely on images from a CT Chest scan, but it remains unclear whether Sybil works well in people with a family history of lung cancer. The goals of this study are: 1) to obtain CT Chest images from individuals with a family history of lung cancer in order to test whether Sybil continues to work well, and 2) offer free screening CT scans to qualifying individuals. It is expected that 250 people will take part in this research study.

Inclusion Criteria:

• Age: Must meet both the upper and lower age limit criteria.
• Upper age limit: ≤80 years of age
• Lower age limit:
• ≥40 years of age OR
• ≥18 years of age AND ≤10 years of youngest relative's age at time of lung cancer diagnosis (e.g., if a relative was diagnosed at 35 years of age, participant can enroll at ≥25 years of age)
• Positive family history of lung cancer (defined as):
• Has ≥1 first-degree relative, OR
• Has ≥2 second-degree relatives with a diagnosis of non-small cell lung cancer or small cell lung cancer (NB: a first-degree relative = parent, sibling, or child, a second-degree relative = grandparent, blood-related aunt or uncle, grandchild, blood-related niece or nephew, half-sibling)

Exclusion Criteria:

• Must not have a personal history of lung cancer at the time of enrollment.
• Must not have a personal history of stage IV cancer of any type at the time of enrollment.
• Must not have had surgical removal of any portion of the lung, excluding needle or core lung biopsy at the time of enrollment.
• Must not have had a chest CT within 12 months prior to trial enrollment.
