Background:
Lung cancer screening (LCS) using low-dose computed tomography (LDCT) can reduce lung cancer mortality; however, screening uptake remains low.
Purpose:
This study aimed to identify factors influencing LDCT-LCS participation among high-risk individuals in Vietnam.
Methods:
A cross-sectional study was conducted among 3288 high-risk individuals (aged 50-74) in Hanoi, Vietnam, in 2024. Potential participants were informed about the LCS project through mass media and local commune health stations. Eligible individuals were subsequently invited for fully subsidized LDCT. Demographic data, health status, behaviors, and LCS-related factors were collected through structured interviews. Logistic regression and classification tree models were used to assess the factors associated with LCS participation.
Results:
Overall, the LCS participation rate was 63.87%. Women who did not drink alcohol had the highest participation (88.7%), while men with irregular health checkups, good health, and past smoking had the lowest (11.4%). Key predictors for higher LCS participation included higher education (adjusted odds ratio = 1.48; 95% CI: 1.25-1.74), high-risk occupations (1.51; 1.22-1.86), current smoking (4.37; 3.06-6.23), ≥30 pack-years of smoking (1.66; 1.41-1.95), family cancer history (3.11; 2.46-3.94), regular exercise (1.44; 1.19-1.75), and regular health checkups (2.42; 2.05-2.85). Lower participation was linked to high income (0.50; 0.42-0.59), drinking alcohol (0.43; 0.35-0.51), and normal/good self-perceived health (0.21; 0.15-0.29).
Conclusions:
This study highlights the complexity of participation in LCS, revealing the interplay of multiple interrelated factors influencing individuals' engagement in the screening process. These findings underscore the urgent need for community awareness campaigns and contextually tailored interventions to enhance LCS uptake in Vietnam.

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
