Vaccination for pancreatic ductal adenocarcinoma: A hard nut to crack

Abstract

No immunotherapy strategy is yet offering consistent results against pancreatic ductal adenocarcinoma. A randomized clinical trial testing repeated immunization with a Listeria monocytogenes-based vaccine encoding for mesothelin in combination with a GM-CSF-transfected allogeneic pancreatic cell vaccine reports no survival benefit for the vaccinated patients.
