Clinical significance of preoperative neutrophil-lymphocyte versus platelet-lymphocyte ratio in patients with operable colorectal cancer

摘要

The objective of this study was to clarify whether the neutrophil-lymphocyte ratio (NLR) and the platelet-lymphocyte ratio (PLR) are significant prognostic markers in patients with resectable colorectal cancer (CRC). A total of 200 patients who underwent curative resection for CRC were enrolled.The NLR and PLR were positively correlated (p < 0.001). Both the NLR and PLR were shown to be good prognostic biomarkers of overall survival (OS) (p = 0.002 and p = 0.001, respectively). The PLR was an independent prognostic factor of OS based on multivariate analysis (hazard ratio, 1.971 ; 95% confidence interval, 1.102-3.335;p=0.021).
