Feasibility of Obtaining and Characterizing Circulating Tumorigenic Cells in Patients With Pancreatic Adenocarcinoma

Patients with pancreatic adenocarcinoma will be enrolled. Venous blood is collected in a standard 10 ml heparin blood collection tube. We may ask for blood samples at different times during the course of the study, specifically, before you start treatment and when your treatment changes. During the one year of the study, the physician anticipates blood samples will be collected a minimum of one and a maximum of four times. The amount of blood collected at any of these times will be 10 mL, about 1 tablespoon.
