High neutrophil to lymphocyte ratio (NLR) can be a predictor of poor outcomes in various malignancies, including pancreatic cancer (PC). Based on these data, we investigated NLR as prognostic markers in MPC pts who received first-line chemotherapy with nab-paclitaxel/gemcitabine; furthermore a prognostic model using inflammatory-based scores to predict survival was planned.


We assessed 70 pts with histologically confirmed MPC who received chemotherapy with nab-paclitaxel/gemcitabine at two different European oncologic centres between January 2012 and November 2015. The cut-off for the NLR was 5. Variables assessed for prognostic correlations included age ≥ 66, sex, Karnofsky PS score, primary tumor site, baseline CA19.9 level ≥ 59xULN, 12-week decrease of CA19.9 level ≥ 50% from baseline, basal bilirubin level, baseline neutrophil to lymphocyte ratio, biliary stent implantation and liver metastasis. Survival analyses were generated according to the Kaplan-Meier method. Univariate and multivariate analyses were performed by Cox proportional hazard model.


With a median follow up of 32 months, median PFS and OS were 7.0 months (95% C.I. 6.221 – 7.779) and 12 months (95% C.I. 9.926-14.074), respectively with a 12-month OS rate of 34.3%. According to NLR values, the patients were divided into two groups. Median PFS and OS were 5 months and 7 months (p= 0.02) and 7 months and 13 months (p= 0.003) in high (NLR ≥ 5) and low (NLR


Baseline NLR is an indipendent predictor of survival of patients with MPC receiving palliative chemotherapy and could be useful to develop a simple clinical score to identify a subgroup of patients with a low chance to benefit from chemotherapy.
