Implementation planning for lung cancer screening in China.

Area of Science:

• Oncology
• Public Health
• Radiology

Background:

• Lung cancer is the leading cause of cancer death in China, with mortality increasing significantly.
• While low-dose computerized tomography (LDCT) screening improves survival in Western trials, smoking's lower contribution to lung cancer in China necessitates tailored approaches.

Purpose of the Study:

• To review existing lung cancer screening programs in China.
• To discuss the challenges and requirements for establishing effective, China-specific LDCT screening strategies.
• To highlight the urgent need for further research to address the lung cancer epidemic.

Main Methods:

• Review of 23 completed or ongoing lung cancer screening programs in China since the 1980s.
• Analysis of preliminary results from Chinese programs, indicating a distinct high-risk subpopulation.
• Discussion of implementation factors including population recruitment, screening protocols, nodule management, and cost-effectiveness, drawing on international evidence.

Main Results:

• Most Chinese LDCT screening programs have reported preliminary findings suggesting a different high-risk lung cancer subpopulation compared to Western countries.
• Current Chinese screening programs often lack stringent smoking-based entry criteria.
• International evidence on LDCT screening implementation exists, but China-specific data is limited.

Conclusions:

• China requires the development of specific lung cancer screening strategies, potentially integrating tobacco control measures.
• The high-risk population eligible for screening in China has not yet been definitively confirmed.
• Urgent, China-focused research is essential to combat the escalating lung cancer epidemic effectively.
