ANXA2 and pancreatic adenocarcinoma: Recently, annexin A2, a 36KD calcium‐dependent phospholipid‐binding protein of the annexins family encoded by the ANXA2 gene, has been identified as a novel biomarker in PAAD as elevated ANXA2 expression was found to significantly correlate with poorer overall survival (OS) and disease‐free survival (DFS) of PAAD patients [12].
