The C-reactive Protein to Prealbumin Ratio Is an Independent Prognostic Factor for Patients With Gastric Cancer Who Receive Curative Surgery.

Background/aim: The C-reactive protein to prealbumin ratio (CPAR) has been proposed and introduced in gastrointestinal cancer management. This study aimed to evaluate the clinical impact of the CPAR in patients with gastric cancer (GC) who received curative treatment.
Patients and Methods: This study included 447 patients who underwent curative treatment for GC between 2013 and 2017. The prognosis and clinicopathological parameters were compared between patients with high and low CPARs.
Results: Overall survival (OS) stratified by each clinical factor was compared using the log-rank test, and a significant difference was observed using a pretreatment CPAR of 5.0. Significant differences were observed in the 3- and 5-year OS rates of the CPAR-low (CPAR <5.0) and CPAR-high (CPAR ≥5.0) groups. The 3- and 5-year OS rates were 92.6% and 87.8%, respectively, in the CPAR-low group and 88.0% and 75.4% in the CPAR-high group. The CPAR was determined to be a significant prognostic factor for OS in a multivariate analysis (p=0.032). Similar results were observed for recurrence-free survival.
Conclusion: The CAPR is a prognostic factor for GC patients. Therefore, the CAPR may be a promising nutritional biomarker of inflammation that can be applied in the management of GC patients.
