Preoperative inflammatory or nutritional biomarkers and clinicopathological features may be survival predictors in resectable esophageal squamous cell carcinoma.We included 118 patients with resectable squamous esophageal carcinoma (stages I-IV), assessing preoperative CRP- and albumin-based modified Glasgow prognostic score, the modified controlling nutritional status score, C-reactive protein, neutrophil/lymphocyte ratio, platelet/lymphocyte ratio, pathologic stage, and tumor location(s), looking for correlation with overall survival and relapse-free survival. Using univariate and Cox analysis, we selected the most reliable prognostic factors.Five-year overall survival and recurrence-free survival were 54.9% and 48.5%, respectively. C-reactive protein values correlated negatively with hypoalbuminemia (P = 0.0036). On univariate analysis, tumor stage, invasion depth, location, nodal involvement, albumin, and modified Glasgow prognostic score were significant prognostic factors for overall and recurrence-free survival. Preoperative C-reactive protein was prognostic factor for overall survival, but not for relapse-free survival (P = 0.017, 0.063, respectively). The Cox proportional hazards model showed the modified Glasgow prognostic score to be an independent prognostic factor for relapse-free survival and overall survival after using the stepwise variable selection procedure. Cox analysis including clinicopathological factors and modified Glasgow prognostic scores showed that only tumor location(s) and pathologic stage were independent prognostic factors for overall survival and recurrence-free survival.Although the modified Glasgow prognostic score is not superior to pathologic stage and tumor location as a biomarker of preoperative nutrition/inflammation and clinicopathological factors, it remains an important prognostic marker in resectable esophageal cancers. Preoperative decreased inflammatory response and improved nutritional status may contribute to prognosis in patients with esophageal cancer. |
