    Abstract:
    BACKGROUND: Preoperative nutritional and immunological patient factors have been found to be associated with prognostic outcomes of malignant tumors; however, the clinical significance of these factors in pancreatic ductal adenocarcinoma (PDAC) remains controversial. OBJECTIVE: The aim of this study was to evaluate the prognostic value of nutritional and immunological factors in predicting survival of patients with PDAC. METHODS: Retrospective studies of 329 patients who underwent surgical resection for PDAC and 95 patients who underwent palliative surgery were separately conducted to investigate the prognostic impact of tumor-related factors and patient-related factors, including Glasgow Prognostic Score (GPS), modified GPS, Prognostic Nutritional Index (PNI), neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio, and lymphocyte/monocyte ratio. RESULTS: In multivariate analysis for patients with surgical resection for PDAC, PNI was an independent factor for overall survival (OS) and disease-free survival. The median OS of patients with PNI ≤ 45 was significantly shorter than that of patients with PNI > 45 (17.5 and 36.2 months, respectively; p < 0.001). In multivariate analysis for patients undergoing palliative surgery for PDAC, only NLR was an independent prognosis factor. The median OS of patients with NLR > 5 was significantly shorter than that of patients with NLR ≤ 5 (2.7 and 8.9 months, respectively; p < 0.001). CONCLUSIONS: PNI in patients with surgical resection and NLR in patients with palliative surgery for PDAC may be useful prognostic factors.
