[Reflections on screening tests for lung cancer]

Area of Science:

• Oncology
• Public Health
• Radiology

Background:

• Lung cancer screening remains a contentious topic with significant global mortality concerns.
• Primary prevention strategies for lung cancer require further development.
• Projected increases in lung cancer mortality in Europe necessitate re-evaluation of screening protocols.

Purpose of the Study:

• To evaluate the effectiveness of annual minimal mass roentgen screening for lung cancer.
• To compare the stage distribution and resection rates of screened versus unscreened individuals.
• To assess the potential impact of screening on treatment outcomes and quality of life.

Main Methods:

• Analysis of data from over 4.3 million individuals undergoing annual minimal mass roentgen screening in Hungary.
• Comparison of oncological staging and resection rates between screened and symptomatic, unscreened patient groups.
• Retrospective analysis of screening program data.

Main Results:

• Screened, asymptomatic individuals showed higher detection rates in earlier stages (Stage 1: 21.4%) compared to symptomatic, unscreened individuals (Stage 1: 8.7%).
• The resection rate was significantly higher in the screened group (34.3%) than in the unscreened group (13.7%).
• Minimal mass roentgen screening facilitates earlier lung cancer detection.

Conclusions:

• Annual minimal mass roentgen screening enables earlier diagnosis of lung cancer.
• Earlier detection through screening offers improved treatment possibilities, potentially enhancing survival rates and patient quality of life.
• The effectiveness of minimal mass roentgen screening for lung cancer warrants a comprehensive revision.
