Abstract:
Objective To investigate the relationship between the staging of endoscopic ultrasonography(EUS) and the expression of carcinoma metastasis associated genic in the patients with gastric carcinoma.Methods Sixty-three patients with gastric cancer were diagnosed by electric gastroscopy and EUS.The preoperative staging of gastric cancer was measured by EUS and compared by pathologic staging and MMP-9 expression.MMP9 level of peripheral serum was measured by enzyme-linked immunosorbent assay,while the expression of MMP-9 protein was tested by immunohistochemistry and hybridization in situ in the gastric carcinoma tissue.Results The total accuracy rate of EUS in estimating invasive depth of gastric cancer was(80.95)%,while that of lymphatic metastasis was(73.02)%.The expression level of MMP-9 in serum was consistent with the expression of MMP-9 protein and MMP-9 mRNA in tissue,which was closely correlative with invasive degree,staging with EUS,lymphatic metastasis in gastric cancer(P
