Clinical Utility of a Plasma-Based miRNA Signature Classifier Within Computed Tomography Lung Cancer Screening: A Correlative MILD Trial Study

In an effort to provide diagnostic information complementary to radiographic screening for lung cancer, the authors evaluated the diagnostic performance of plasma mRNA.  The mRNA signature classifier demonstrated 87% sensitivity and 81% specificity, with a negative predictive value of 99%.  In contrast, low dose CT had a sensitivity of 79% and a specificity of 81%.  Combining the mRNA signature classifier and low dose CT resulted in a 5-fold decrease in false positive findings based on CT alone.
