Objective:To detect precancerous lesions of gastric cancer and biopsy tissue vascular endothelial growth factor (VEGF)and mutant p53 gene(mtp53)expression,to explore the development of clinical significance of VEGF and mutant p53 gene in gastric cancer.Methods:19 cases by endoscopic biopsies of normal gastric tissues,22 cases of intestinal metaplasia,47 cases of gastro-intestinal mucosal dysplasia, 54 cases of gastric cancer samples by immunohistochemical staining to detect the expression levels of VEGF and mtp53′s.Results: The expression levels of VEGF, mtp53 in normal gastric mucosa, intestinal metaplasia, dysplasia, and gradually increased gastric cancer was the law.mtp53 of VEGF expression in gastric carcinoma and compared with normal gastric tissue,intestinal metaplasia was significantly higher(P<0.05),but with atypical hyperplasia was no significant difference(P>0.05). Conclusion: The abnormal expression of VEGF and mutant p53 may be related to the degree of deterioration of the stomach tissue lesions related.
