Abstract:
Objective To investigate the expression and clinical significance of pro-inflammation S100A9 protein in intestinal type gastric cancer.Methods We retrospectively analyzed the clinicopathological materials of the 278 patients who were diagnosed as Lauren classification intestinal gastric cancer and underwent surgical treatment between January and December 2008 at the Department of General Surgery,Zhongshan Hospital Fudan University.Immunohistochemistry was used to analyze the expression of S100A9 protein in tumor tissues and para-tumor tissues.Results High expression of S100A9 protein was associated with the depth of tumor invasion (P =0.013),lymph node metastasis (81.4％,53.9％,47.3％ vs.84.7％,69.3％,60.7％,x2 =4.220,P =0.041) and TNM stage (P =0.010).The overall survival rate of these patients with high expression of S100A9 protein was significantly lower than those with low expression of S100A9 protein.In stage Ⅲ/Ⅳ patients,the overall survival rate of these patients with high expression of S100A9 protein was significantly lower than those with low expression of S100A9 protein.Moreover,for those patients who received postoperative chemotherapy,the prognosis of the patients with high expression of S100A9 protein was poorer than those with low expression.By multivariable analysis,the expression of S100A9 protein was not an independent risk factor for the prognosis of intestinal gastric cancer patients.Conclusions High expression of S100A9 protein in intestinal gastric cancer was associated with poor prognosis.
