Objective:

To assess the predictive potential of a model based on DNA methylation biomarkers for lung cancer risk among both ever and never smokers.

Approach:

Key Findings:

• The model demonstrated the ability to predict both short-term and long-term lung cancer risk.
• The study included both ever and never smokers, addressing a gap in current screening guidelines.

Interpretation:

The findings suggest that DNA methylation biomarkers can enhance lung cancer risk prediction, potentially including never smokers in screening strategies.

Limitations:

• The study's applicability may be limited to the populations studied in Germany and Norway.
• The model's performance in diverse populations and settings remains to be evaluated.

Conclusion:

The study highlights the potential of DNA methylation biomarkers in predicting lung cancer risk, which could inform future screening practices.

• Cochrane meta-analysis
• ESTHER Study
• HUNT Study
