Relation Between Cachexia, Diabetes and periNeural Invasion in PANcreatic Cancer- Biomarkers Substudy

The purpose of this study is to determine the interrelationship between cachexia, neural invasion and diabetes in patients with pancreatic cancer. Thus the investigators propose to identify the protein expression levels of Activin and Midkine in plasma of patients with different stages of pancreatic adenocarcinoma compared with healthy patients and to evaluate the possible correlation with diabetes, tumor size and tumor stage.
