The aim of this study is to systematically evaluate the prognostic significance of above nutritional and inflammatory indexes for overall survival (OS) and surgical complications in esophageal cancer patients.Methods: Esophageal cancer patients who underwent esophagectomy were retrospectively collected. PNI, NLR, PLR, and SII were introduced to evaluate the baseline nutritional and inflammatory status.Results: A total of 407 patients were included in the present study. Kaplan–Meier survival analysis revealed that PNI-low group, NLR-high group and PLR-high group, all showed a significantly shorter OS (34.38% vs 49.46%, P < 0.001; 36.13% vs 48.26%, P = 0.026 and 33.33% vs 48.52%, P = 0.001 respectively), while no significant difference was found in SII groups (42.33% vs 46.31%, P = 0.067). Multivariable analyses identified PNI (P = 0.002) was an independent prognostic factor for OS, but NLR (P = 0.672) and PLR (P = 0.186) were not. Postoperative complications occurred significantly more frequently in the low-PNI group (29.69% vs 13.26%, P < 0.001). However, no significant differences were found in the postoperative complication rates between different NLR (16.67% vs 22.69%, P = 0.124), PLR (18.03% vs 19.61%, P = 0.867) and SII (15.34% vs 20.49%, P = 0.326) groups. Multivariate logistic regression analysis showed only PNI (P = 0.008) was an independent prognostic factor for postoperative complications.Conclusion: Preoperative low PNI was not only an independent prognostic factor for worse survival in esophageal cancer patients but also associated with high incidence of postoperative complications.Keywords: esophageal cancer, prognostic nutritional index, prognosis, postoperative complications |
