What the trial is, and whether it could suit you

CA19-9 is an acidic glycoside containing sialic acid, called ganglioside. Lewis blood group antigen is the precursor for the synthesis of CA19-9, which is formed by the combined action of sialic acid transferase and fucosyltransferase (FUT3). The ability to produce soluble blood group substances is determined by the alpha (1,2) fucosyltransferase gene (FUT2), which can be divided into secretory Se, weakly secretory Sew, and non secretory SE. The Lewis antigen positive (Lewis+) population has normal CA19-9 secretion function, while the Lewis antigen negative (Lewis -) population (about 7%) usually shows no or low secretion of CA19-9. Therefore, when CA19-9 is used as a biomarker, the combined detection of Lewis antigen status is a marker to judge the prognosis of pancreatic cancer, which can divide pancreatic cancer patients into high/medium/low malignant phenotypes.
