RESUMO
BACKGROUND: We examined the significance of neutrophil lymphocyte ratio(NLR)in gastric cancer and colon cancer in the perioperative period. METHOD: There were 46 patients(21 with gastric cancer and 25 with colon cancer). We examined the association between preoperative NLR and other indicators of nutritional status, as well as the relationship between preoperative NLR and the incidence of postoperative complications(all complications/infectious complications). RESULT: NLR was higher in those with zinc<65 mg, prognostic nutritional index(PNI)≤40, and modified Glasgow prognostic score(mGPS)of 2 (p<0.05). NLR showed no difference among all patients with complications(12 cases), but was higher in patients with infectious complications(p<0.05). CONCLUSION: Preoperative NLR is correlated with PNI as a predictor of infectious complications.
