Evaluation of insulin-like growth factor (IGF-1) and retinol binding protein (RBP-4) levels in patients with newly diagnosed pancreatic adenocarcinoma (PDAC)

Diabetes accompanying PDAC does not influence the level of IGF-1 as opposed to diabetes in the course of CP. The IGF-1 level can be useful for early diagnosis of PDAC. High concentration of RBP-4 is not specific to pancreatic cancer, so it does not appear to be a useful biomarker for PDAC.
