Abstract

Backgrounds/Aims: The aim of this study was to investigate the prognostic significance of neutrophyil?lymphocyte ratio (NLR), platelet- lymphocyte ratio (PLR), CRP and CA19-9 in patients were diagnosed with pancreatic ductal adenocarcinoma (PDAC) to better verify pre-operative risk stratification and management.
Methods: This retrospective study included data from 133 consecutive patients with PDAC, who were treated between 2013 and 2015. PDAC diagnosis was made by cytology or assumed by radiological assessment or surgical resection samples. All clinico-pathological data were retrieved from medical records at our institution. The laboratory data were obtained before any treatment modality. Dates of death were obtained from the central registry.
Results: There was a statistically significant relation between radiological staging and CA19-9 and survival (p=0.001, p=0.005) and there are significant differences in CA19-9 level between stage I and III, I and IV, II and III, and II and IV. Both CRP and CA19-9 levels were statistically significantly higher in patients with radiological lymph node metastasis than patients with N0 disease (p=0.037, p=0.026). NLR and CA19-9 levels were also higher in metastatic disease (p=0.032, p=0.007). According to Spearman’s correlation analysis, we found in all patients that there was a negative correlation between the survival time and CRP and neutrophil count (p=0.019, p=0.011).
Conclusions: Preoperative CRP, CA19-9 and NLR are simple, repeatable, inexpensive and well available marker, can give information on lymph node and solid organ metastasis and survival, give clues to prognosis and be useful in clinical staging of patients with PDAC.
