Abstract

Background: Pretherapy serum neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have both been identified as prognostic in pancreatic ductal adenocarcinoma (PDAC). The aim of this study was to identify the prognostic implication of pretherapy NLR and PLR in patients with resectable PDAC. Methods: Data were collected retrospectively on patients operated at our institution between 2004 and 2014. A Cox proportional hazards model was used to investigate the relationship between clinical and pathological parameters, NLR and PLR to overall survival (OS). Survival data were analyzed using the Kaplan–Meier method. Results: 217 patients were analyzed with a median overall survival (OS) of 17.5 months. Factors identified as being predictive of OS by univariate analysis included age, receipt of adjuvant therapy, margin positivity, pathologic angiolymphatic invasion, T-stage, and N-stage (P < 0.05). Factors identified as being independently predictive of OS by multivariate analysis included age and angiolymphatic invasion (P < 0.05). NLR and PLR were not predictive of OS. Survival analysis demonstrated no difference in OS in patients who had high or low NLR or PLR. Discussion: Pretherapy NLR and PLR do not predict survival in patients who underwent pancreatectomy for PDAC at our institution.
