Abstract

There are reports that the use of regional anesthesia (RA) may be associated with better perioperative surgical stress response in cancer patients compared with general anesthetics (GA). However, the role of anesthesia on the magnitude of the postoperative systemic inflammatory response (SIR) in colorectal cancer patients, within an enhanced recovery pathway (ERP), is not clear. The aim of the present study was to examine the effect of anesthesia, within an enhanced recovery pathway, on the magnitude of the postoperative SIR in patients undergoing elective surgery for colorectal cancer. Database of 507 patients who underwent elective open or laparoscopic colorectal cancer surgery between 2015 and 2019 at a single center was studied. The anesthetic technique used was categorized into either GA or GA + RA using a prospective proforma. The relationship between each anesthetic technique and perioperative clinicopathological characteristics was examined using binary logistic regression analysis. The majority of patients were male (54%), younger than 65 years (41%), either normal or overweight (64%), and were nonsmokers (47%). Also, the majority of patients underwent open surgery (60%) and received mainly general + regional anesthetic technique (80%). On univariate analysis, GA + RA was associated with a lower day 4 CRP (≤150/>150 mg/L) concentration. On day 4, postoperative CRP was associated with anesthetic technique [odds ratio (OR) 0.58; confidence interval (CI) 0.31–1.07; P = .086], age (OR 0.70; CI 0.50–0.98; P = .043), sex (OR 1.15; CI 0.95–2.52; P = .074), smoking (OR 1.57; CI 1.13–2.19; P = .006), preoperative mGPS (OR 1.55; CI 1.15–2.10; P = .004), and preoperative dexamethasone (OR 0.70; CI 0.47–1.03; P = .072). On multivariate analysis, day 4 postoperative CRP was independently associated with anesthetic technique (OR 0.56; CI 0.32–0.97; P = .039), age (OR 0.74; CI 0.55–0.99; P = .045), smoking (OR 1.58; CI 1.18–2.12; P = .002), preoperative mGPS (OR 1.41; CI 1.08–1.84; P = .012), and preoperative dexamethasone (OR 0.68; CI 0.50–0.92; P = .014). There was a modest but an independent association between RA and a lower magnitude of the postoperative SIR. Future work is warranted with multicenter RCT to precisely clarify the relationship between anesthesia and the magnitude of the postoperative SIR.
