LUNG CANCER, INTERSTITIAL LUNG DISEASE
Interstitial lung abnormalities (ILA) are CT scan findings suggestive of interstitial lung disease (ILD). These can be observed in individuals who have no prior diagnosis or suspicion of (ILD) [Progressive fibrotic ILD is among the most clinically significant forms of ILD with respect to morbidity and mortality [Evaluating CT lung cancer screening (CTLS) cohorts may provide an opportunity to identify ILA and undiagnosed ILD. The individuals in these cohorts are high-risk for ILD by virtue of their smoking history, and most are followed over a period of years which can capture progression. In this study, we evaluated the prevalence of ILA, the associations with mortality, hospitalization and lung cancer, and the incidence and timing of subsequent ILD diagnosis, including IPF, among participants in our institution’s clinical CTLS program.
