S100P and xiap expression in pancreatic ductal adenocarcinoma: Potential novel biomarkers as a diagnostic adjunct to fine needle aspiration cytology
Carcinoma, Pancreatic Ductal
X-Linked Inhibitor of Apoptosis Protein
Two novel biomarkers have very high sensitivity and specificity in the diagnosis of PDA in RSs. S100P has slightly lower sensitivity and higher specificity of PDA than XIAP in EUS-FNA specimens. We recommend using both biomarkers as cytological diagnostic adjuncts, especially in difficult cases of well-differentiated PDA versus reactive ductal epithelium.
