Role of Prognostic Nutritional Index in patients with gastric cancer: a meta-analysis.

The aim of this study was to determine the role of Prognostic Nutritional Index in predicting gastric cancer.Studies were searched in PubMed, EMBASE and ISI Web of Science. The hazard ratios and 95% confidence interval for survival estimate were extracted from the articles and the pooled HR was computed.Nine studies with 3203 participants met the inclusion criteria. Low PNI was associated with poor overall survival (pooled HR 1.92, 95% CI: 1.68-2.19).Prognostic Nutritional Index was an effective indicator for the prognosis of gastric cancer.
