Highlights• Systematic review and meta-analysis of preoperative corticosteroids in surgery for GI cancers • Reports significant association between preoperative corticosteroids and lower postoperative IL-6 and CRP • The relationship between corticosteroids and lower postoperative systemic inflammatory response may underpin the impact on postoperative complications This meta-analysis examined the impact of preoperative corticosteroids on interleukin 6 (IL-6), C-reactive protein (CRP), and complications following surgery for gastrointestinal cancer.

Methods:A systematic review was performed using appropriate keywords. Random-effects metaanalysis was performed.Results:11 RCTs with 474 patients, were included. Corticosteroids were significantly associated with lower IL-6 on postoperative day 1 (mean difference -148 pg/mL, 95% CI -205 to -92, p<0.001), 2 (-33 pg/mL, 95% CI -58 to -8, p=0.01), and 3 (-31 pg/mL, 95% CI -52 to -11, p=0.002), lower CRP on day 3 (-45 mg/L, 95% CI -68 to -21, p<0.001), and 7 (-14 mg/L, 95% CI -27 to -1, p=0.04), and fewer postoperative infective complications (OR 0.47, 95%CI 0.26 to 0.83, p=0.01).
Conclusion:Corticosteroids were associated with reduction in the postoperative systemic inflammatory response and complications following surgery for gastrointestinal cancer.
