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 <0.01) .The expres-sion of survivin was different in gastric cancers:survivin expression rate was 76.92%in poorly differentia-ted gastric carcinomas, 75.00%in T3 ~T4 gastric carcinomas, 75.61%in the positive lymph node metas-tasis of gastric cancers, and 77.08%in the Ⅲ~Ⅳ gastric cancer tissues; which was significantly higher than the highly differentiated (51.61%), T1 ~T2(38.89%), lymph node-negative (51.72%), andⅠ~Ⅱperiod (40.91%) ( P <0.05).The expression of survivin in gastric cancers was no obvious correlation with the age, gender and tumor site ( 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 <0.01) .The expression of LYVE-1 was different in gastric cancers:LYVE-1 expression rate was 40.38%in T3 ~T4 gastric carcinomas, 46.34%in the positive lymph node metastasis of gastric canc-ers, 41.67% in the Ⅲ ~Ⅳ gastric cancer tissues; which was significantly higher than the T1 ~T2 (11.11%), lymph node-negative (13.79%), andⅠ~Ⅱperiod (13.64%) ( P <0.05).The expres-sion of LYVE-1 in gastric cancers was no obvious correlation with the age, gender, tumor site, and the de-gree of differentiation ( 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.
