Abstract
Lung cancers are often diagnosed at advanced stages with concomitant poor prognosis, making it the leading cause of cancer mortality worldwide. Herein, we aim to validate a panel of protein biomarkers identified from tumor cell-derived exosomes in liquid biopsies as diagnostic biomarkers for lung cancer. Biomarker candidates were identified by quantitative proteomics analyses. Verification and validation of exosomal candidates were performed by western blot and ELISA, respectively. The diagnostic performance for early detection of non-small-cell lung carcinoma was assessed using Receiver Operating Characteristic (ROC) curve analyses. Compared to current cancer biomarker, CEA, several novel exosome proteins were discovered to have greater diagnostic value in lung cancer. Importantly, these exosome proteins and their signatures demonstrated excellent diagnostic performance in the early detection of lung cancer. Hence, the promising results derived from our exosome biomarker studies warrant a large-scale clinical trial.Biography
