Few investigations discussing an association between ABO blood groups and pancreatic cancer exist. We have selected a series of 224 patients with histologically-confirmed pancreatic cancer, and their ABO blood groups distribution was compared with two control groups: 7086 patients with various diseases (Group 1) and 7320 voluntary blood donors (Group 2). There was an increased number of pancreatic cancer among the patients with blood group B (relative risk 1.5 vs Group 1 p = 0.021; 1.7 vs Group 2 p = 0.0025) and a decreased number in patients with blood group O, when compared with the two control groups.

Abstract
Few investigations discussing an association between ABO blood groups and pancreatic cancer exist. We have selected a series of 224 patients with histologically-confirmed pancreatic cancer, and their ABO blood groups distribution was compared with two control groups: 7086 patients with various diseases (Group 1) and 7320 voluntary blood donors (Group 2). There was an increased number of pancreatic cancer among the patients with blood group B (relative risk 1.5 vs Group 1 p = 0.021; 1.7 vs Group 2 p = 0.0025) and a decreased number in patients with blood group O, when compared with the two control groups.
