Abstract:
Objective To explore the relationship between systemic immune inflammatory index and ferritin(SF)and the clinicopathologic features and prognosis of gastric cancer(GC).Methods A retrospective analysis was conducted on 152 gastric cancer patients who underwent D2 gastrectomy at the Radiation Oncology Department of Qingbaijiang District People's Hospital in Chengdu from January 2017 to December 2020.Neutrophil count was divided by lymphocyte count to calculate Neutrophil to lymphocyte ratio(NLR).The SF level in plasma was evaluated by ELISA kit.According to the results of multivariate analysis,a new prognosis prediction system including NLR-SF score(NSS)was established.Results Multivariate Cox regression analysis showed that NLR(HR=1.053,95%CI=1.014~1.094,P=0.007),tumor grade(HR=1.944,95%CI=1.279~2.955,P=0.002)and SF(HR=1.005,95%CI=1.002~1.008,P=0.002)were independent factors affecting the prognosis of GC patients.ROC analysis showed that when the cutoff value of SF was 215.5,the AUC of predicting the death of GC patients was 0.800(95%CI=0.731~0.869),the sensitivity was 68.5%,and the specificity was 86.7%.When the cutoff value of NLR was 3.36,the AUC of predicting the death of GC patients was 0.869(95%CI=0.810~0.928),the sensitivity was 81.5%,and the specificity was 91.7%.Higher NSS was significantly correlated with the number of lymph node metastasis>3 cases,the number of deaths,the increase of neutrophil,platelet,SF,NLR and PLR levels(P<0.05),and the decrease of lymphocytes(P<0.05).Kaplan-Meier survival curve analysis showed that the higher the NSS,the shorter the survival time(χ2=75.168,P<0.001).ROC analysis showed that the AUC of NSS in predicting the death of GC patients was 0.902(95%CI=0.852~0.952),the sensitivity was 90.2%,and the specificity was 80.0%.Conclusions This study confirms that NLR and SF are independent prognostic factors of GC patients,and the NSS constructed by combining them is of great value in predicting the overall postoperative survival.
