Abstract:
Objective:To evaluate the impact and predictive value of neutrophil-to-lymphocyte ratio( NLR) ,derived neutrophil-to-lymphocyte ratio( d-NLR) ,platelet-to-lymphocyte ratio( PLR) and lymphocyte-to-monocyte ratio( LMR) on the prognosis of patients with colorectal cancer with curative resection.Methods: Retrospective analysis of 205 cases of clinical data and returning data after patients with colorectal cancer surgery,ROC curve was applied to determine thresholds for four biomarkers and their prognostic values were assessed using Kaplan-Meier curve,univariate and multivariate COX regression models of patients with NLR,D-NLR,PLR and LMR and other clinicopathological factors and the relationship between the 5-year recurrent-free survival( RFS).Results:According to the ROC curve,LMR could not be used as a potential diagnostic biomarker for subsequently analysis,for its AUC was less than 0.50, The optimal cut-off values were 3.12 with the highest specificity and sensitivity ( 75% and 73.1%) for NLR, while in the univariate analysis show,NLR,D-NLR and PLR were all risk factors of poor recurrence-free survival ( P<0.05 ) , the multivariate regression analysis,NLR≥3.12 and colorectal cancer staging were independent risk factors of prognosis of colorectal cancer.Conclusion:NLR≥3.12 can provide improved accuracy for predicting clinical outcomes in surgical CRC patients under surgery resection.
