Lung Cancer Risk for Patients Undergoing Cardiac Chest CT: Identification of a New High Risk Population for Lung Cancer Screening.
Patients getting heart scans show unexpectedly high lung cancer rates and represent a readily identifiable group who could benefit from earlier cancer screening.
This Stanford 13-year retrospective study of 17,232 cardiac CT patients demonstrates that this population has a lung cancer incidence significantly higher than the general population, yet the majority (including 72 lung cancer cases) did not qualify for USPSTF-guideline lung cancer screening at the time of their cardiac CT. The findings suggest that cardiac CT recipients—who already have documented cardiovascular risk factors—represent a novel, readily identifiable high-risk cohort for opportunistic lung cancer screening, with implications for guideline expansion.

Why it surfaced
Large single-center retrospective (n=17,232) identifying cardiac CT recipients as underserved high-risk lung cancer screening population; EARLY_CANCER_DETECTION flag triggers HIGH priority despite score 7. Actionable finding: advocacy for broader chest imaging in this population. Design quality=1 for retrospective single-center.
