Purpose. To examine the effects of the administration of perioperative sivelestat, a selective neutrophil elastase inhibitor, on tumor immunity and inflammatory mediators in patients who undergo major surgery. Methods. Thirteen patients admitted to the hospital for elective surgery were equally randomized into one of two groups: the Sivelestat group (n = 6) and the control group (n = 7). Thereafter, the immunosuppressive acidic protein (IAP), serum interleukin-6 (IL-6), and type 1/type 2 T-helper cell balance were all assessed at several time points before and after surgical intervention. Results. The serum IL-6 values at 1 and 12h after surgery and on postoperative days 1 and 3 were all significantly lower in the sivelestat group than in the control group. The IAP values at postoperative days 7 and 28 in the sivelestat group were also significantly lower than those in the control group. There was a significant correlation between the IL-6 level at 1h after surgery and the IAP level at postoperative days 7 and 28. Conclusions. In this preliminary study, the perioperative administration of sivelestat was thus suggested to reduce surgical stress by decreasing the cytokine release and preserving the antitumor immunity.
