In this study, we aimed to determine the influence of systemic inflammation-based scores and nutrition status on the outcome in patients receiving chemotherapy for unresectable pancreatic cancer. Patients and Methods: A total of 93 consecutive patients who underwent chemotherapy for unresectable pancreatic cancer at Osaka Medical College Hospital, Takatsuki, Japan, between January 2008 and December 2014 were eligible for this study. The outcomes assessment included one- and two-year overall survival (OS) rates, according to changes in LMR and PNI prior to, and following chemotherapy. Results: LMR<3.4 (OR=5.02, 95%CI=1.559-19.85, p=0.005) and PNI<43 (OR=3.53, 95%CI=1.057-14.21, p=0.03) independently predicted a poor outcome in patients receiving chemotherapy for unresectable pancreatic cancer using multivariate analysis. According to changes in LMR and PNI prior to, and following chemotherapy, compared to patients who maintained LMR≥3.4, patients whose LMR decreased from ≥3.4 to <3.4 had significantly lower OS rates (p<0.001). Similarly, compared to patients who maintained PNI≥43, patients whose PNI deteriorated had significantly lower OS rates (56.2% versus 25.8% at one year, and 12.5% versus 0% at two years; p=0.003). Conclusion: LMR<3.4 and PNI<43 are identified as independent predictors of poor outcome in patients receiving chemotherapy for unresectable pancreatic cancer. LMR and PNI may help clinicians identify patients at high risk for poor prognosis. ER -
