Liao X, et al. - Researchers performed this investigation to assess the prognostic biomarkers for patients with early-stage pancreatic ductal adenocarcinoma (PDAC) after pancreaticoduodenectomy. In this work, they constructed a prognostic signature of 9 genes that demonstrated good performance for predicting 1-year overall survival. A new prospect for prognostic biomarkers of PDAC after pancreaticoduodenectomy provided in this work could have a value in clinical application.
