Screening for lung cancer in the middle-aged

Area of Science:

• Public Health
• Radiology
• Oncology

Background:

• A long-standing lung disease screening program has been active in the German Democratic Republic for over 30 years.
• The program utilizes biennial posterior-anterior chest X-rays for individuals aged 40 and above.

Purpose of the Study:

• To evaluate the effectiveness of the lung disease screening program in reducing lung cancer mortality.
• To assess the relative risk of lung cancer death associated with participation in the latest screening round.

Main Methods:

• Analysis of data from a population-based screening program.
• Biennial chest X-ray examinations (70 x 70 mm posterior-anterior).
• Comparison of lung cancer mortality risk between participants and non-participants in screening rounds.

Main Results:

• For individuals under 60, the adjusted relative risk of dying from lung cancer was 0.93 (95% CI 0.65-1.33) for those in the last screening round compared to those screened previously but not in the last round.
• The confidence interval includes 1, indicating no statistically significant difference in mortality risk.

Conclusions:

• The current lung cancer screening program, based on biennial chest X-rays, did not demonstrate a significant reduction in mortality for the under-60 population.
• Further investigation into the optimal screening strategies and target populations for lung cancer is warranted.
