- Abstract
BACKGROUND: Perioperative blood transfusion in pancreatic cancer patients has been linked to decreased survival;however, a causal mechanism has not been determined. During the processing and storage of packed erythrocytes,biologically active molecules accumulated in the acellular plasma fraction; therefore, the authors hypothesized thatthe plasma fraction of stored packed erythrocytes promoted tumor progression. METHODS: Proliferation and migration of murine pancreatic cancer and control cells were determined in vitro in response to the plasma fraction fromleukocyte and nonleukocyte-reduced fresh versus stored packed erythrocytes. Last, an immunocompetent murinemodel was used to assess the effect of the plasma fraction of stored and processed packed erythrocytes on pancreatic cancer progression. RESULTS: Incubation of pancreatic cancer cells with the plasma fraction of packed erythrocytes increased proliferation and migration. Intravenous delivery of the acellular plasma fraction to mice withpancreatic cancer significantly increased the tumor weight in both leukocyte-reduced and nonleukocyte-reducedpacked-erythrocyte groups (P < .01), although tumor growth and morbidity were greatest in the nonleukocyte-reduced group. CONCLUSIONS: The plasma fraction of stored packed erythrocytes promoted murine pancreatic cancer proliferation and migration in vitro and when administered intravenously, significantly augmented pancreaticcancer growth in immunocompetent mice.
