摘要
Abstract
Objective To investigate the relation between Vav3 expression and tumor invasion and metastasis in gastric cancer tissue and the clinical significance. Methods We collected the paraffin specimens of gastric cancer tissue and carcinoma side normal tissue from 92 patients who received resection for gastric carcinoma in the Third Surgery Department of the Fourth Affiliated Hospital of Hebei Medical University from May 2014 to May 2015. The expressions of Vav3,RelA,PCNA and MMP-2 in gastric cancer tissue and carcinoma side normal tissue were detected by immunohistochemistry staining. The relation between Vav3 expression and clinical and pathological characteristics in gastric cancer tissue was analyzed. The relation among Vav3, RelA,PCNA and MMP-2 expression was investigated by Spearman correlation analysis. Results The positive expression rate of Vav3 in gastric cancer tissue was 78. 3% (72 / 92),higher than 40. 2% (37 / 92)in carcinoma side normal tissue( χ2 = 27. 572,P ﹤ 0. 001). The positive expression rate of RelA in gastric cancer tissue was 88. 0% (81 / 92),higher than 52. 2% (48 / 92)in carcinoma side normal tissue(χ2 = 28. 242,P ﹤ 0. 001). The positive expression rate of PCNA in gastric cancer tissue was 73. 9% (68 / 92),higher than 47. 8% (44 / 92)in carcinoma side normal tissue(χ2 = 13. 143,P ﹤ 0. 001) . The positive expression rate of MMP-2 in gastric cancer tissue was 69. 6% ( 64 / 92 ),higher than 48. 9% ( 45 / 92 )in carcinoma side normal tissue( χ2 = 8. 125,P = 0. 004 ) . There was no significant difference in gender,age,depth of infiltration,and distant metastasis between high expression of Vav3 and low expression of Vav3 ( P ﹥ 0. 05 ) . There was significant difference in tumor differentiation degree,tumor diameter and the extent of lymph node metastasis between high expression of Vav3 and low expression of Vav3(P ﹤ 0. 05). The expression of Vav3 had positive correlation with the expression of RelA,PCNA and MMP-2(rs = 0. 338,P ﹤ 0. 001;rs = 0. 225,P = 0. 031;rs = 0. 267,P = 0. 010). The expression of RelA had positive correlation with the expression of PCNA( rs = 0. 336,P = 0. 001);the expression of RelA had no linear correlation with the expression of MMP-2(rs = 0. 176,P = 0. 094). The expression of PCNA had no linear correlation with the expression of MMP-2(rs = 0. 188,P = 0. 072). Conclusion There is overexpression of Vav3 in gastric cancer tissue,and the increase of Vav3 is associated with tumor metastasis and progress. Vav3 is involved in the progress and metastasis of gastric cancer by regulating RelA,PCNA and MMP-2 expression.关键词
