Abstract

Purpose: No tumor marker has been shown to be useful in screening for pancreatic cancer. CA 19–9 is a widely used serological marker for pancreatic cancer, however, its role in screening and establishing the diagnosis of early stage disease is limited. Recently, syndecan-1 has been shown to be overexpressed early in pancreatic carcinogenesis. This transmembrane heparan sulfate-bearing proteoglycan can regulate adhesion, migration, and growth factor activity, processes critical to the early metastatic potential of pancreatic cancer. Syndecan-1 is frequently shed into the blood from malignant tissues. Indeed, serological assessment of this cell surface proteoglycan has been shown to be a useful marker in the diagnosis/prognosis in lung cancer and myeloma. Therefore, we hypothesized that serum syndecan-1 levels would be an accurate marker for pancreatic cancer.
