ABSTRACT
Objective To investigate the expressions and clinical significance of survivin, and lymphatic vessel endothelial hyaluronan receptor 1 ( LYVE-1) in gastric cancers.Methods The expres-sions of survivin and LYVE-1 were detected with streptavidin avidin-peroxidase ( SP) immunohistochemical method in 70 cases of gastric cancers and 50 cases of normal gastric tissues.The relationship between the expressions of survivin and LYVE-1 with the clinicopathological parameters was analyzed.Results The ex-pression rate of survivin was 65.71%(46/70) in gastric cancers, and 6.00% (3/50) in normal gastric tissues, with statistically significant difference between two groups (χ2 =43.048, P 0.05).The expression rate of LYVE-1 was 32.86%(23/70) in gastric cancers, and 4.00%(2/50) in gastric ulcers, with significant difference between two groups (χ2 =14.726, P 0.05 ) .There was a positive correlation between expressions of survivin and LYVE-1 in gastric cancers ( r =0.271, P <0.05).Conclusions Survivin and LYVE-1 were abnormally expressed in gastric cancers with a colose relationships between two parameters.They might play important roles in tumorigenesis and progression of a gastric cancer.
