The prognostic significance of inflammation-based markers in patients with recurrent gastric cancer

Abstract

Purpose

The aim of this study was to evaluate the prognostic impact of inflammation-based markers, including the neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI), in patients with recurrent gastric cancer (RGC).

Methods

This study reviewed 167 patients with RGC. A receiver operating characteristics (ROC) curve analysis was performed to determine the NLR and PNI cutoff values. The prognostic significance of the NLR and PNI was evaluated by a multivariate analysis.

Results

The optimal NLR and PNI cutoff values for predicting the 1-year survival after recurrence were 2.2 and 47, respectively. A univariate analysis revealed that the NLR (p < 0.001) and PNI (p < 0.001) were significantly associated with the survival time after recurrence, along with the histology, peritoneal recurrence, carbohydrate antigen 19-9, and chemotherapy for recurrence. In the multivariate analysis, a higher NLR (p < 0.001) and a lower PNI (p = 0.002) were independent predictors of a shorter survival time. Among the patients who underwent chemotherapy, the NLR and PNI were also independent prognostic factors.

Conclusions

Inflammation-based markers, including the NLR and PNI, are simple and useful clinical biomarkers that can be used to predict the survival time of patients with RGC.
