The relationship between anaesthetic technique, clinicopathological characteristics and the magnitude of the postoperative systemic inflammatory response in patients undergoing elective surgery for colon cancer

The magnitude of the postoperative systemic inflammatory response (SIR) is now recognised to be associated with both short and long-term outcomes in patients undergoing surgery for colon cancer. During such surgery, it is unclear whether the anaesthetic regimens influence the magnitude of the postoperative SIR, independent of other factors. The aim of the present study was to examine the association between anaesthetic agents, clinicopathological characteristics and the magnitude of the postoperative SIR in patients undergoing elective surgery for colon cancer. Patients with colon cancer who underwent elective open or laparoscopic surgery between 2008 and 2016 (n = 409) were studied at a single center. The relationship between type of anaesthesia, surgical technique; open (n = 241) versus laparoscopic (n = 168) and clinicopathological characteristics was examined by using chi-square testing. The chi-square test was used to determine which anaesthetic group influences the POD 2 CRP for only patients undergoing elective open colon surgery. The majority of patients were
