ABSTRACT
Objective@#To assess the clinical value of neutrophil-to-lymphocyte ratio (NLR) in predicting anastomotic leak of postoperative rectal cancer patients.@*Methods@#The clinical data of 787 rectal cancer patients who underwent anterior resection from January 2014 to December 2017 in Affiliated Tumor Hospital of Zhengzhou University were collected. The postoperative numbers of white blood cell (WBS) on postoperative day (POD)1, 3 and 5 were detected, and the NLR was calculated. The relationship of NLR and the incidence of anastomotic leak was analyzed, and the area under the receiver-operating characteristic (ROC) curves was calculated. The accuracy of postoperative NLR in predicting the incidence of anastomotic leak was evaluated.@*Results@#WBC counts of patients with leak on POD1, POD3 and POD5 were 13.2×109/L, 9.1×109/L and 8.9×109/L, respectively, while those of patients without leak were 12.9×109/L, 9.0×109/L and 8.8×109/L. The WBC count was not significantly different between patients with or without leak (P>0.05). The average NLR values of patients with or without leak were 13.3 and 11.6 on POD1, 10.9 and 7.6 on POD3, 9.3 and 5.3 on POD5, respectively. The NLR values of patients with leak on POD3 and POD5 were significantly higher than those of patients without leak (P<0.05). The cutoff value of NLR on POD3 was 8.6, the sensitivity and specificity of detecting the leakage was 73.2% and 75.6%, respectively, and the area under curve (AUC) was 0.744. The cutoff value of NLR on POD5 was 5.5, the sensitivity and specificity was 69.6% and 75.5%, the AUC was 0.726. The multivariate analysis result showed that NLR >8.6 was an independent factor for anastomotic leak prediction.@*Conclusion@#Postoperative NLR on day 3 is useful in predicting anastomotic leak and can decrease the incidence of complication in rectal cancer patients who underwent anterior resection.
