Figure 3From: Perioperative immune responses in cancer patients undergoing digestive surgeriesPerioperative changes of measurements of IFN-γ in surgical patients. (Black squares – gastric resection (n = 40), black circles – colorectal resection (n = 34), black triangles – hepatic resection (n = 20), white squares – laparoscopic cholecystectomy(n = 12)). There were no significant differences in the percentage of CD4+ IFN-γ+T cells among all groups prior to surgery. Significant decrease, however, in the postoperative percentage of CD4+ IFN-γ+T cells were not seen other than the reduction on POD 2 in the hepatic resection group.Back to article page
