Background

CA242 is a tumor marker for sialylated Lewis carbohydrates associated with adenocarcinomas and e-selectin-mediated metastatic risk. It is commonly tested along with CEA, CA19-9, and CA242 for detecting pancreatic cancer. The specificity of CA242 is higher than similar markers. Current research dictates that diagnostic efficiency is highest when various tumor markers are tested for at once.
