OBJECTIVE: The modified Glasgow Prognostic Score (mGPS) is an inflammation-based measure of malnutrition that reflects a state of cachexia in cancer patients. We evaluated mGPS as an index to predict surgical site infection (SSI) incidence in patients undergoing colorectal cancer surgery. SUBJECTS AND METHODS: We retrospectively analyzed 351 patients who underwent colon cancer resection. Factors correlated with the incidence of SSIs were identified by logistic analysis and stepwise selection. RESULTS: SSIs were observed in 32 patients, with an incidence of 9.1%. Univariate logistic analysis revealed mGPS (Score 2), laparotomy, resection of other organs, colostomy, excessive blood loss (>423 mL), long duration of surgery (>279 minutes), pulmonary dysfunction, prognostic nutritional index (PNI) ≤40, neutrophil lymphocyte ratio (NLR)(>4), and controlling nutritional status (CONUT) ≥2 to be associated with an increased incidence of SSIs. Multivariate analysis with variables selected by the stepwise procedure also revealed mGPS (Score 2) (Odds ratio (OR) =3.55, 95% Confidence interval (CI) 1.30-9.56; p=0.01), colostomy (OR=6.56, 95%CI 1.60-31.38; p=0.01), excessive blood loss (OR=3.20, 95%CI 1.23-8.42; p=0.02), and NLR (>4)(OR=3.24, 95%CI 1.31-8.17; p=0.01) to be independent risk factors. CONCLUSION: mGPS is an independent risk factor for SSIs. Our results suggest that cachexia before surgery in patients with colorectal cancer might predict the incidence of SSIs.
