Lung Cancer Screening in Asia: An Expert Consensus Report

Area of Science:

• Oncology
• Public Health
• Radiology

Background:

• Lung cancer incidence and mortality are highest in Asia.
• Early diagnosis is crucial for effective lung cancer treatment and reduced mortality.
• Healthcare disparities in Asia necessitate tailored lung cancer screening and diagnostic approaches.

Purpose of the Study:

• To discuss and recommend affordable and accessible lung cancer screening modalities for the Asian population.
• To address the unique challenges of lung cancer screening and early detection in Asian countries.

Main Methods:

• A virtual Steering Committee meeting was convened with 19 advisors from 11 Asian countries.
• Discussions focused on identifying cost-effective and accessible lung cancer screening methods suitable for Asian populations.

Main Results:

• Key risk factors for lung cancer in Asian smokers include age (50-75) and smoking history (≥20 pack-years); family history is significant for non-smokers.
• Annual low-dose computed tomography (LDCT) is recommended for patients with abnormalities and risk factors.
• Screening cessation is advised for individuals over 80 or those unable/unwilling to undergo curative treatment.

Conclusions:

• Implementing LDCT screening in Asia faces challenges like economic limitations and lack of government programs.
• Strategies are proposed to overcome these barriers and improve early lung cancer detection in Asia.
