Journal Article
Which Nutritional Scoring System Is More Suitable for Evaluating the Short- or Long-Term Prognosis of Patients with Gastric Cancer Who Underwent Radical Gastrectomy?
2020
Overview
Objective
To evaluate the effects of three nutritional scoring systems: Prognostic Nutritional Index (PNI), Controlling Nutritional Status (CONUT), and Naples Prognostic Score (NPS) on the short- or long-term prognosis of gastric cancer (GC) patients who underwent radical gastrectomy.
Methods
The clinicopathological data of 2182 patients who underwent radical gastrectomy at the Fujian Medical University Union Hospital (FMUUH) from 2009 to 2014 were retrospectively analyzed. The effects of the PNI, CONUT, and NPS on the short- or long-term prognosis of GC patients were analyzed.
Results
Overall, 359 (16.5%) patients had postoperative complications. There was no significant association between the PNI, CONUT, and NPS and postoperative complications (
P
> 0.05); however, high CONUT and NPS were significantly associated with severe postoperative complications (
P
< 0.05). Univariate analysis showed that PNI, CONUT, and NPS were all associated with overall survival (OS) (
P
< 0.001). However, multivariate analysis showed that only PNI was an independent risk factor for OS (
P
= 0.004), and the 5-year OS rate in the low PNI group was significantly lower than that in the normal PNI group (55.5% vs 75.4%,
P
< 0.05). The area under the curve (AUC) and the c-index of PNI were significantly higher than those of CONUT and NPS. The prognostic efficiency of combining PNI and TNM stage was also significantly better than that of TNM staging alone (
P
< 0.05).
Conclusion
The current study demonstrated that CONUT and NPS are important for assessing the risk of severe postoperative complications. However, PNI is an independent risk factor for the long-term prognosis of GC patients who underwent radical gastrectomy and can improve the prognostic efficiency of TNM staging.
