Therefore, the aim of this study was to explore the suitability of integrin αvβ6, CEA, hepatocyte growth factor receptor (cMET), EGFR, epithelial cell adhesion molecule (EpCAM), HER2, uPAR, and VEGFR2 as molecular targets for tumor-targeted imaging of pancreatic adenocarcinoma patients. The gene discussed is CEACAM5; the disease is pancreatic adenocarcinoma.
