BackgroundPreoperative nutritional and inflammatory indices have been reported to be associated with the prognosis of patients with malignancy. We evaluated clinicopathological factors, including nutritional and inflammatory indices, and recurrence prognosis in patients with stage IIA colon cancer (CC) who underwent curative surgery.MethodsThis retrospective study included 197 patients with stage IIA CC who had undergone curative resection. We evaluated the association between prognostic nutritional index (PNI), neutrophil-lymphocyte ratio (NLR), and platelet-lymphocyte ratio (PLR) with clinicopathological factors and prognosis for recurrence. For the recurrence-free survival (RFS) analysis, receiver operating characteristic (ROC) curves were used to determine appropriate cutoff values for PNI, NLR, and PLR.ResultsUnivariate analyses showed that PNI<44.8 (P = 0.028) was significantly associated with worse RFS in patients with stage IIA CC patients. In the multivariate analyses, PNI<44.8 (hazard ratio [HR] 2.082; 95% confidence interval [CI] 1.005-4.317; P = 0.049) independently and significantly predicted RFS.ConclusionPNI is a useful marker for predicting recurrence prognosis in post-resection patients with stage IIA CC.Copyright © 2020 Elsevier Inc.
