Abstract

Background: Low circulating levels of adiponectin are associated with the occurrence of infection after surgery in patients with cancer. Data are lacking on whether surgical stress is associated with a reduction in circulating levels of adiponectin. Furthermore, the relationship between oxidative stress and postoperative complications has not been investigated.

Objective: The aim of this study was to evaluate the pre-, intra-, and postoperative levels of adiponectin in patients who underwent major abdominal surgery for malignancy and their association with postoperative complications.

Methods: An observational, prospective, single-center study was conducted in patients undergoing abdominal surgery for cancer. Circulating levels of adiponectin and of two biomarkers of oxidative stress were measured preoperatively, at the end of surgery, 24 and 48 hours after surgery. Patients were divided into two groups: complicated (CL+) and uncomplicated (CL-), according to the Clavien-Dindo classification. Temporal patterns of adiponectin and markers of oxidative stress were followed at different time points.

Results: Twelve patients were enrolled, seven with postoperative complications (CL+) and five without (CL-). The preoperative median levels of adiponectin were statistically different between CL+ and CL- groups (3.2 µg/ml vs 10.9 µg/ml; p=0.03). Levels of preoperative adiponectin were inversely related to the severity of postoperative complications (Rho= -0.68; p= 0.02). Pre-, intra- and postoperative levels of oxidative stress products were not statistically different between the two groups. Adiponectin levels decreased during surgery in both groups, while those of oxidative stress tended to increase.

Conclusions: Preoperative adiponectin levels correlate with postoperative complications after cancer surgery.

Keywords: Adiponectin, cancer surgery, oxidative stress, postoperative complications, surgical stress.
