Background: Recent studies suggested that galectin-3 may act as a pro-inflammatory damage-associated molecular pattern. The aim of this study is to investigate the association between blood galectin-3 and postoperative complications (POC) after colorectal cancer (CRC) surgery.
Methods: Blood samples were taken from 35 patients with CRC before surgery, immediately after surgery, and on postoperative days (POD) 1, 3, 5, and 7. Blood galectin-3 and interleukin-6 levels were measured by commercially available ELISA. Patients were divided into those with (POC group) and without POC (no-POC group).
Results: Significantly higher galectin-3 levels were observed pre- and postoperatively in the POC group (n=10) compared with those of the no-POC group (n=25). Galectin-3 levels on POD1 showed the best predictive potential for POC (cut-off: 3.18 pg/mL, area under the curve: 0.868).
Conclusions: These results indicate that increased perioperative blood galectin-3 levels may be associated with POC after CRC surgery.
