Among tumor markers, carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA 19-9), and Duke pancreatic monoclonal antigen type 2 (DUPAN-2) were within normal ranges, but cytokeratin-19 fragment (CYFRA 21-1) was elevated to 4.1 ng/mL (reference range: <3.5 ng/mL). This evidence concerns the gene CEACAM5 and neoplasm.
