Lung cancer screening eligibility?

Lung cancer screening eligibility?

• A. 50-80 with 20 pack-year
• B. 55-80 with 30 pack-year current or quit within 15 years
• C. 60-75 with 15 pack-year
• D. 40-50 with 10 pack-year

Answer: (B)

Screening with low-dose CT is targeted to adults at high risk from long-term smoking. The best match is someone aged roughly 55 to 80 years with a 30-pack-year smoking history who currently smokes or quit within the past 15 years. This profile reflects the group shown in key studies and guidelines to benefit from annual LDCT screening, balancing the potential to reduce lung-cancer deaths against the harms of screening. The other scenarios fall short because they either have a lower pack-year history, reducing the expected benefit, or fall outside the age range that has demonstrated a favorable balance of benefits and harms.
