[Lung cancer screening - risk stratification : Who should undergo screening?]

Area of Science:

• Oncology
• Radiology
• Preventive Medicine

Background:

• Lung cancer is a leading cause of death, with advanced stages limiting curative treatment options.
• Early diagnosis is crucial for improving patient prognosis and enabling potentially curative interventions.
• Current screening methods benefit high-risk individuals, necessitating refined risk stratification.

Purpose of the Study:

• To review risk stratification models from major European and American lung cancer screening studies.
• To explore potential future biomarkers for improving lung cancer risk assessment.
• To enhance the effectiveness of computed tomography (CT) screening by targeting high-risk populations.

Main Methods:

• Review of large-scale European and American lung cancer screening studies.
• Analysis of risk stratification models used in these studies.
• Discussion of emerging biomarkers for risk assessment.

Main Results:

• High-risk populations (e.g., older age, smoking history, family history, overweight) show the most benefit from lung cancer screening.
• Computed tomography (CT) screening effectiveness is maximized when focused on identified high-risk groups.
• Existing risk stratification models aid in targeting screening efforts.

Conclusions:

• Early lung cancer detection is vital for improving survival rates.
• Targeted screening of high-risk populations using CT is effective.
• Future research should focus on novel biomarkers to further refine lung cancer risk stratification and screening strategies.
