				        	 Objective:To assess the predictive value of the platelet-to-lymphocyte ratio(PLR), neutrophil-to-lymphocyte ratio(NLR)and tumor-related factors on the peritoneal metastasis in advanced gastric cancer patients.
				        	
				        
				        	Methods:A total of 701 pathologically confirmed gastric cancer patients who underwent surgery at the First Affiliated Hospital of Wenzhou Medical University between Jan 2009 and Jan 2012 were enrolled.
				        	
				        
				        	Results:Univariate analysis indicated that tumor location, tumor size, serosal invasion, depth of invasion, pathological type, lymph node metastasis and PLR were related to peritoneal metastasis(all P<0.05). According to the area under the ROC curve, the optimal cutoff value of PLR for predicting peritoneal metastasis was 132.43 (sensitivity 71.8%, specificity 50.6%). There were significant differences in tumor size, TNM stage, lymph node metastasis and serosal infiltration between high PLR group and low PLR group. Multivariate Logistic analyses revealed that PLR (HR=2.205, P=0.003), lymph node metastasis(HR=3.113, P=0.010)and tumor size(HR=1.150, P=0.014) were independent risk factors for peritoneal metesfasis.
				        	
				        
				        	Conclusions:Preoperative PLR is valuable in predicting peritoneal metastasis of advanced gastric cancer and it is an independent risk factor for peritoneal metastasis of gastric cancer.
