Popis: Usefulness of various nutritional indices for management of patients with esophageal squamous cell carcinoma (ESCC) has been reported. Although Controlling Nutritional Status (CONUT) score is among promising indices to predict outcome, the optimal timing for its measurement during the perioperative period remains unknown. Here the prognostic value of the CONUT score was assessed among patients with ESCC.We analyzed 464 patients who underwent subtotal esophagectomy of ESCC, of which 276 patients were treated with neoadjuvant treatment (NAT). The significance of the associations between candidate parameters including the CONUT score and postoperative prognosis were evaluated.Among the 25 candidate predictors, the preoperative CONUT score had the highest correlation with overall survival (OS) after surgery. Patients were categorized as follows: normal, mild, and moderate or severe, on the basis of the preoperative CONUT score. OS was significantly shortened as the CONUT score worsened. Multivariable analysis revealed that the CONUT scores of the subgroups mild (Hazard ratio [HR] 1.69) and moderate or severe (HR 2.18) were independent predictors of poor prognosis for OS. Furthermore, in an analysis limited to patients who underwent NAT, OS was significantly shortened as the preoperative CONUT score worsened. On the contrary, there was no significant difference in RFS among patient groups stratified by the CONUT score determined before NAT.Our study indicates that the preoperative CONUT score serves as a prognosticator in resectable ESCC. The preoperative CONUT value was more useful than that before NAT in patients administered NAT.
