The C‐reactive Protein to Albumin Ratio Predicts Long‐Term Outcomes in Patients with Pancreatic Cancer After Pancreatic Resection

Abstract

BACKGROUND: The C-reactive protein to albumin (CRP/Alb) ratio, a novel inflammation-based prognostic score, is associated with outcomes in septic patients. The prognostic value of CRP/Alb ratio has not been established in cancer patients. The aim of this study is to evaluate the significance of CRP/Alb ratio in therapeutic outcome after pancreatic resection for pancreatic cancer. METHODS: The study comprised 113 patients who had undergone pancreatic resection for pancreatic cancer between April 2001 and December 2011. We retrospectively investigated the relation between CRP/Alb ratio and disease-free as well as overall survival. RESULTS: The optimal cut-off level of the CRP/Alb ratio was 0.03. For disease-free survival, preoperative biliary drainage (p = 0.011), advanced tumor-node-metastasis (TNM) classification (p = 0.002), and higher CRP/Alb ratio (p = 0.049) by univariate analysis, and advanced TNM classification (p = 0.003) by multivariate analysis, were independent and significant predictors of cancer recurrence. For overall survival, preoperative biliary drainage (p = 0.012), advanced TNM classification (p = 0.001), and higher CRP/Alb ratio (p = 0.023) by univariate analysis, and advanced TNM classification (p = 0.003) and higher CRP/Alb ratio (p = 0.035) by multivariate analysis, were independent and significant predictors of poor patient outcome. CONCLUSIONS: The CRP/Alb ratio may be an independent and significant indicator of poor long-term outcomes in patients with pancreatic cancer after pancreatic resection.
