20-year study shows that lung cancer screening boosts survival rates
By Kate Madden Yee
Diagnosing early-stage lung cancer with low-dose CT translates to a 20-year survival rate of 81%, according to a large-scale study.
November 7, 2023
(A, B) Two annual repeat low-dose CT scans in a woman who was 60 years old at baseline enrollment in 1999. At baseline enrollment, she was currently smoking and had a 30-pack-year smoking history. No nodules were identified on baseline low-dose CT scans. On the sixth annual low-dose CT scan (B), a right lower lobe solid nodule (arrow) measuring 4.5 mm in maximum diameter was identified. The nodule could be identified in retrospect on the prior annual CT scan (arrow in A), when it measured 2 mm in maximum diameter. Estimated tumor volume doubling time was 161 days. Lobectomy was performed two months later, and diagnosis of stage 1aN0M0 moderately differentiated adenocarcinoma measuring 6 mm in maximum diameter was made. Expert pathologic panel review (22) of the pathologic specimen updated the diagnosis to adenocarcinoma with mixed subtype (80% acinar, 20% bronchoalveolar carcinoma components) with 5 mm of invasion.

Risk-based lung cancer screening mitigates healthcare disparities
By Kate Madden Yee
Risk-based lung cancer screening using a model called the PLCOm2012-Update appears to mitigate racial and ethnic disparities and improve screening performance compared with a protocol based on the USPSTF 2021 criteria.
