Overall survival (OS) of patients with high and low PNLR. (A) Kaplan-Meier OS curves in months from the diagnosis of metastatic adenocarcinoma of patients with PNLR below and above the cut-off of 2,000. Log-rank test P<0.001; (B) forest plot results of the logistic regression analysis using the Cox-proportional hazards model of OS as the outcome variable and PNLR, age, CEA (≤5 µg/L), LDH (>210 U/L), metastasectomy and ECOG >1 at presentation of metastatic disease as the predictor variables. PNLR, platelet-neutrophil to lymphocyte ratio; ECOG PS, Eastern Cooperative Oncology Group performance status; CEA, carcinoembryonic antigen; LDH, lactate dehydrogenase; HR, hazard ratio.
