The Impact of Fibrinogen to Prognostic Nutritional Index Rate on Prognosis of Pancreatic Ductal Adenocarcinoma

Introduction: The aim of the present study was to evaluate the prognostic value of the ratio of serum fibrinogen to prognostic nutritional index (PNI; Fbg/PNI) in patients undergoing resection for pancreatic ductal adenocarcinoma.Methods: A total of 140 patients who had undergone resection for pancreatic cancer were included. Patients were divided into two groups according to a Fbg/PNI >= 8.8 or <8.8. Survival data were analyzed using the log-rank test for univariate analysis and Cox proportional hazards for multivariate analysis.Results: Fbg/PNI was a significant prognostic indicator in univariate analysis for overall survival (OS) and disease-free survival (DFS). Fbg/PNI retained significance in multivariate analysis for OS (hazard ratio, 1.81; 95% confidence interval, 1.19-2.77; P < .01) in addition to tumor differentiation and nodal involvement. Fbg/PNI was a significant independent prognostic indicator of poor DFS on multivariate analysis (hazard ratio, 1.54; 95% confidence interval, 1.05-2.26; P = .03).Conclusion: Preoperative Fbg/PNI is a novel significant independent prognostic indicator for OS and DFS following resection of pancreatic cancer with curative intent.
