Of the 165 pancreatic and periampullary adenocarcinoma specimens collectively present on the TMA, 159 specimens (96 %) could successfully be microscopically quantified for integrin αvβ6 expression, 158 (96 %) for CEA, 159 (96 %) for cMET, 156 (95 %) for EGFR, 151 (92 %) for EpCAM, 152 (92 %) for HER2, 155 (94 %) for VEGFR2, and 152 (92 %) for uPAR. Here, PLAUR is linked to periampullary adenocarcinoma.
