    Abstract:
    PURPOSE: We evaluated prognostic indicators based on inflammatory and nutritional factors, namely, the modified Glasgow Prognostic Score (mGPS), the Prognostic Nutritional Index (PNI), the neutrophil/lymphocyte ratio (NLR), and the platelet/lymphocyte ratio (PLR), to determine their efficiency and significance after pancreaticoduodenectomy for pancreatic cancer. METHODS: The subjects of this study were 46 patients who underwent pancreaticoduodenectomy for pancreatic cancer between October 2007 and December 2014. Patients were divided into preoperative mGPS (0/1 and 2), PNI (<40 and ≥40), NLR (<2.5 and ≥2.5), and PLR (<200 and ≥200) groups, to evaluate various perioperative outcomes. RESULTS: Hemoglobin concentrations were significantly lower (P = 0.019), whereas intra-abdominal bleeding was significantly higher (P = 0.040) in the PNI (<40) group than in the PNI (≥40) group. The incidence of postoperative pneumonia was significantly higher in the mGPS (2) group (P = 0.009), and surgical complications greater than grade 3 (Clavien-Dindo classification) were significantly increased in the NLR (≥2.5) group (P = 0.041). Overall survival rates in the PNI (<40) (P = 0.019), NLR (≥2.5) (P = 0.001), and PLR (≥200) (P < 0.001) groups were significantly lower than those in the other groups. The PLR was the only independent prognostic indicator (P = 0.002) according to multivariate analysis. CONCLUSIONS: The mGPS, PNI, and NLR were effective predictive indicators of postoperative complications. The PLR was the most useful prognostic indicator for pancreatic cancer patients after pancreaticoduodenectomy.
