2026 IASLC CT Screening and Early Detection Symposium-IASLC CT Screening and Early Detection Symposium (Ticketed)

Video Summary

The workshop opened with an overview of the day’s agenda on lung cancer screening and early detection, covering biomarkers, never-smoker screening, broader health benefits, and AI.  <br /><br />The first session focused on biomarkers. Speakers emphasized that biomarkers should be developed in the target population, using pre-diagnostic samples, adequate sample sizes, and independent validation cohorts. Blood-based protein biomarkers and radiomics were presented as promising tools, but speakers stressed that high AUC alone is not enough: calibration, clinical utility, cost-effectiveness, and implementation feasibility are essential.  <br /><br />The never-smoker session highlighted that lung cancer is increasingly important in people who have never smoked, especially in Asia. Presentations showed that risk-based screening using family history, environmental exposures, and AI may identify high-risk never-smokers while avoiding overdiagnosis. A patient advocate shared a powerful personal story of being diagnosed after an incidental scan, underscoring the need for equitable screening access.  <br /><br />The “beyond cancer detection” session explored incidental findings such as cardiovascular disease, COPD, emphysema, ILD, osteoporosis, and breast abnormalities. Speakers argued that low-dose CT can reveal major treatable comorbidities, but only if there are clear pathways for reporting, follow-up, and action.  <br /><br />The AI session covered AI for nodule detection, malignancy prediction, workflow streamlining, and quantitative CT metrics. AI may help triage scans, reduce workload, and predict future risk, but must be externally validated and integrated carefully into clinical practice.  <br /><br />The afternoon case review workshop illustrated how early lung cancer can mimic infection or benign disease, reinforcing the need for multidisciplinary assessment, prior imaging comparison, and structured training.
