(A) 70-year-old woman with pulmonary adenocarcinoma who underwent sublobar resection without evidence for pLVI. 15-mm solid nodule with irregular margins present in right lower lobe (arrow). No tumor recurrence on 37-month follow-up. (B) 75-year-old man with pulmonary adenocarcinoma who underwent wedge resection that exhibited pLVI. 19-mm solid nodule with irregular margins and peritumoral interstitial thickening (arrowheads) present in right upper lobe. Ipsilateral mediastinal and hilar lymph node metastasis occurred after 5-month follow-up (not shown).

Axial chest CT examination in a 54-year-old participant. A, On the axial noncontrast chest CT image, the pectoralis muscle (PM) area was segmented and measured in the section above the aortic arch. B, The subcutaneous adipose tissue (SAT) area as the area between the PM and the skin surface on the same section was also measured and the attenuation of pixels in the SAT area was used to determine the individualized threshold for the intermuscular adipose tissue (IMAT). C, The IMAT within the PM was segmented as the areas with Hounsfield units below this threshold for the IMAT (arrowheads). Image courtesy of the Radiological Society of North America

Ultimately, because LYFS-CT may exclude minority patients who could benefit from LCS and underestimate the benefits of LCS, the authors of this AJR article suggested "augmenting LCS eligibility for minority patients using combinations of models"--specifically, the PLCOm2012 model in conjunction with LYFS-CT and USPSTF-2020.
