Selective Plasma Adsorption of Extracellular DNA in Prevention of Intraoperative Metastasis in Pancreatic Cancer (Pilot Study)

The goal of this clinical trial is to learn if selective plasma adsorption of extracellular DNA works to prevent formation of metastases of pancreatic cancer during surgical removal of the tumor. It will also help researchers to learn about the safety of selective plasma adsorption of extracellular DNA during the surgery. The main questions it aims to answer are: * Does selective plasma adsorption of extracellular DNA improve the survival of participants after surgical removal of pancreatic cancer? * Does selective plasma adsorption of extracellular DNA reduce the risk of the recurrence of pancreatic cancer? * What medical problems do participants have when they receive selective plasma adsorption of extracellular DNA during surgical removal of pancreatic cancer? Researchers will compare clinical data of participants who had selective plasma adsorption of extracellular DNA and those who did not to see if there are any differences in their health. Participants who are scheduled for surgical removal of pancreatic cancer by their doctor according to medical indications will: * Either receive selective plasma adsorption of extracellular DNA during surgical removal of pancreatic cancer and on the next day after the surgery, or not. * Do blood tests prior to surgery, during the surgery, on the next day after the surgery, one week after the surgery, 3, 6, 9, and 12 months after the surgery. * Do computed tomography scans 3, 6, 9, and 12 months after the surgery. Participants will receive selective plasma adsorption of extracellular DNA, blood tests, and computed tomography scans for free.
