  • Expressions of Snail and VEGF Gene in Invasion Ductal Carcinoma of Breast

    ObjectiveTo investigate the expressions of Snail and VEGF gene in invasion ductal carcinoma tissues and analyze their clinicopathologic relationship. MethodsThe expressions of Snail and VEGF gene were detected on mammary gland hyperplasia (30 cases), intraductal breast cancer (30 cases), and invasion ductal carcinoma (70 cases) by in situ hybridization, to compare with the expression difference of the two genes in the different pathological changed tissues of mammary gland and among the clinicopathological facters of invasion ductal carcinoma as well as the relationship. ResultsThe expression rate of Snai mRNA in mammary gland hyperplasia, intraductal breast cancer, and invasion ductal carcinoma was 23.3% (7/30), 46.7% (14/30), and 81.4% (57/70), respectively, there was statistical difference among them (χ 2=32.4, Plt;0.05); The expression rate of VEGF mRNA in mammary gland hyperplasia, intraductal breast cancer, and invasion ductal carcinoma was 33.3% (10/30), 50.0% (15/30), and 71.4% (50/70), respectively, there was statistical difference among them (χ 2=13.4, Plt;0.05). The expression rates of Snail mRNA and VEGF mRNA in lymphatic metatasis group were significantly higher than those in no lymphatic metatasis group 〔92.7% (38/41) vs. 65.5% (19/29), χ 2=8.29, Plt;0.05; 85.4% (35/41) vs. 51.7% (15/29), χ 2=9.42, Plt;0.05, respectively 〕. The expression rates of Snail mRNA and VEGF mRNA in Ⅲ-Ⅳ stage of TNM clinical stage were significantly higher than those in Ⅰ-Ⅱ stage 〔939% (46/49) vs. 52.4% (11/21), χ 2=14.14, Plt;0.05; 81.6% (40/49) vs. 47.6% (10/21), χ 2=8.32, Plt;0.05〕. The expressions of Snail mRNA and VEGF mRNA were related to the expressions of ER, PR, HER-2, and vessel cancer embolus (Plt;0.01). The expressions of Snail mRNA and VEGF mRNA were not related to age, tumor size, and histological grade (Pgt;0.05). There was a positive correlation between the expressions of Snail mRNA and VEGF mRNA (r=0.67, Plt;0.05). ConclusionsThe overexpressions of Snail mRNA and VEGF mRNA in invasion ductal carcinoma has a synergetic effect on occurrence and development, therefore, combined detecting the expressions of Snail mRNA and VEGF mRNA are some significance to predict infiltration and metastasis of the invasion ductal carcinoma.
