Abstract
OBJECTIVE: The role of postoperative of the ratio of c-reactive protein to albumin (CRP/Alb ratio) in the prognosis of gastric cancer is rarely evaluated. Our purpose was to investigate the correlation of the postoperative CRP/Alb ratio and long-term prognosis of gastric cancer. METHODS: We enrolled 430 patients who suffered from radical gastrectomy. The commonly used inflammatory indices, clinical-pathological characteristics and oncologic outcomes were recorded. The median was used to the cut-off value for preoperative and postoperative CRP/Alb ratio, respectively. Kaplan-Meier analysis and Cox proportional hazards regression model were performed to determine its prognostic significance. RESULTS: In univariate analysis, there were significant differences were observed in overall survival (OS) according to perioperative CRP/Alb ratio, c-reactive protein (CRP), serum albumin (Alb), respectively. According to the multivariate analysis, higher postoperative CRP/Alb ratio (HR 2.03, 95% CI 1.55-2.66, P < 0.001), lower postoperative albumin (Alb), higher preoperative c-reactive protein (CRP) and higher postoperative CRP were indicated a shorter overall survival. CONCLUSION: Postoperative inflammatory factors in patients with gastric cancer should be pay attention, especially postoperative CRP/Alb ratio may be an independent predictor of long-term prognosis of gastric cancer.
