Significant differences between COP-NLR and age (P<0.001), maximum tumor diameter (P<0.001), WBC count (P<0.001), platelet count (P<0.001), neutrophil ratio (P<0.001), lymphocyte ratio (P<0.001), monocyte ratio (P = 0.028), Hb (P<0.001), LDH (P = 0.039), albumin (P<0.001), fibrinogen (P<0.001), D-dimer (P = 0.001), NLR (P<0.001), intraoperative blood loss (P = 0.030), and survival period (P<0.001) were shown. This evidence concerns the gene GSTM1 and neoplasm.
