Results from Lung Cancer Screening Outreach Utilizing a Mobile CT Scanner in an Urban Area

Area of Science:

• Pulmonology
• Radiology
• Public Health

Background:

• Low-dose CT (LDCT) screening reduces lung cancer mortality in high-risk individuals.
• Barriers to lung cancer screening access persist, necessitating innovative outreach strategies.

Purpose of the Study:

• To assess the outreach and effectiveness of a mobile lung cancer screening program.
• To increase lung cancer screening accessibility and facilitate early detection.

Main Methods:

• A mobile CT unit was deployed in a high-traffic New York City area, offering free LDCT screening.
• Characteristics of the mobile screening cohort were compared to a hospital-based cohort.

Main Results:

• 216 patients underwent mobile LDCT screening.
• Mobile screening engaged younger, uninsured individuals with lower smoking intensity, and diverse ethnicities compared to hospital-based screening.
• Two lung cancers were diagnosed; 28.2% had significant non-cancer findings (e.g., coronary artery calcification, emphysema).

Conclusions:

• Mobile LDCT screening is effective for lung cancer and other findings, reaching distinct high-risk demographics.
• Low screening rates in certain populations highlight the need for strategies addressing diverse access barriers.
• Care navigation is critical for ensuring high-quality care for all patients.
