Immunologic changes to autologous transfusion after operational trauma in malignant tumor patients:Neopterin and Interleukin-2

Objective:To estimate the impact of autologous transfusion on the status of perioperative immune activation inmalignant tumor patients.The Serum Neopterin and Interleukin-2(IL-2)were measured.Methods:Sixty patients undergoingelective radical resection for malignant stomach tumor were enrolled in the prospective study and assigned to the following groups:(Ⅰ)Group A received autologous transfusion;(2)Group H received allogeneic transfusion.The perioperative course(Beforeinduction of anesthesia,after operation and 5 d after operation)of Neopterin and IL-2 was compared.Results:In group A,SerumNeopterin was significantly lower than baseline alter operation and IL-2 had no significant changes.In group H,both SerumNeopterin and IL-2 were significantly lower than baseline alter operation and 5 d after operation.Compared with group A,SerumNeopterin was significantly lower than baseline alter operation and 5 d after operation and IL-2 was significantly lower thanbaseline 5 d alter operation.Conchision:Autologous
