Parameters Of Complete Blood Count Might Predict The Prognosis Of Patients With Advanced Gastric Cancer

Abstract PurposeMetastatic gastric cancer is a common disease with poor prognosis. In this common disease, estimating the prognosis with a simple complete blood count has attracted the attention in many studies. However, the results of the studies are incompatible with each other. The aim of the study was to evaluate the relationship between parameters of the complete blood count and disease prognosis in patients with advanced gastric cancer(AGC).MethodsBetween 2009 and May 2019, the files of patients with AGC were retrospectively evaluated. Blood counts of the patients were examined before receiving any treatment at the time of diagnosis of AGC. All parameters derived from complete blood count and defined in literature were evaluated in this study. These were; Neutrophil lymphocyte ratio(NLR), platelet lymphocyte ratio(PLR), monocyte lymphocyte ratio(MLR), systemic immune-inflammation index(SII), hemoglobin, lymphocyte, platelet. The patients were divided in two subgroups according to the median values of NLR, PLR, MLR and SII.ResultsA total of 105 patients with AGC were included in the study. The median survival in the patients with low NLR group was 14.6 months compared with high NLR group was 7.9 months (p=0.008). In low PLR and MLR group the median survivals were 12.7 and 14.6 months compared with high PLR and MLR were 8.2 and 7.9 months respectively (p=0.019, p=0.06). There was no significant relationship with SII (p=0.375). Multivariate analysis showed that NLR was an independent predictor of overall survival.ConclusionThrough the parameters derived from complete blood count, NLR appears to be a promising prognostic marker in patients with AGC.
