Markers of systemic inflammation, including C-reactive protein (CRP) and white blood cell (WBC), are widely available in clinical practice and are useful to identify patients at risk of infectious complications.6–8 With regard to gastric cancer, the study that has investigated the predictive value of these inflammatory markers for infectious complications is limited.9,10 Furthermore, these studies did not reach a consensus in terms of that what concentration of CRP or what postoperative day is suitable for detecting postoperative infectious complications. This evidence concerns the gene CRP and gastric cancer.
