Objective To explore value of preoperative neutrophil-to-lymphocyte ratio (NLR) combined with carbohydrate antigen 19-9 (CA19-9) in evaluating prognosis for patients with pancreatic head carcinoma.Methods The clinical data of patients with pancreatic head carcinoma underwent radical pancreaticoduodenectomy in the Lanzhou University Second Hospital from February 2011 to August 2017 were retrospectively analyzed. The preoperative serum albumin (ALB), CA19-9, NLR, carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), N stage, tumor differentiated degree, and other indicators were recorded and the patient’s overall survival was recorded. Linear correlation analysis was used to examine the association of NLR with serum CA19-9. The receiver operating characteristic (ROC) curve was used to calculate the cutoff values of NLR and CA19-9 corresponding to the overall survival rate of 2-year. Kaplan-Meier method was used for survival analysis. Cox proportional hazards regression model was used to evaluate the prognostic value of preoperative CA19-9 and NLR.Results ① A total of 121 patients were enrolled in this study. There was no significant correlation between the preoperative serum CA19-9 and NLR (r=0.100 05, P=0.272 9). ② Multivariate analysis showed that higher NLR, higher CA19-9 level, higher N stage, and lower tumor differentiation were the risk factors for overall survival of pancreatic head carcinoma (P<0.05). ③ The cutoff values of CA19-9 and NLR in evaluating the 2-year overall survival rate were 123.3 U/mL and 2.34 respectively by the ROC curve analysis, the area under ROC curve of CA19-9, NLR, and CA19-9 combined with NLR were 0.763, 0.686, and 0.823, respectively. ④ The proportions of patients with CEA≥5 μg/L and ≥N1 stage were higher in the patients with CA19-9≥123.3 U/mL as compared with patients with CA19-9<123.3 U/mL (P<0.05); The proportions of patients with preoperative serum ALB level <35 g/L and CEA≥5 μg/L, ≥N1 stage, and poor differentiation were higher in the patients with NLR≥2.34 as compared with the patients with NLR<2.34 (P<0.05). ⑤ Kaplan-Meier survival analysis showed that patients with CA19-9≥123.3 U/mL and NLR≥2.34 had worse overall survival than those patients with CA19-9<123.3 U/mL and NLR<2.34 (HR=3.599, P<0.01; HR=2.506, P<0.01). The patients with CA19-9≥123.3 U/mL and NLR≥2.34 (n=42), CA19-9≥123.3 U/mL or NLR≥2.34 (n=48), CA19-9<123.3 U/mL and NLR<2.34 (n=31) had better overall survival in turn (overall and between groups, all P<0.01).Conclusion Preoperative serum CA19-9 combined with NLR has an important value in evaluating prognosis for patients with pancreatic head carcinoma.
