Objective To investigate the relationship of vascular endothelial growth factor (VEGF), microvessel density (MVD) and progression of gastric carcinoma (GC). Methods The expression of VEGF and MVD in archival waxembedded specimens of 80 cases of GC and 20 gastric benign disease (GBD) were examined by using immunohistochemical staining. ResultsThe positive expression rate (PER) of VEGF in GC was 75.0%, and in GBD 5.0% (P＜0.05). The PER of VEGF in GC with invasive serosa was 95.5%, in those without serosal invasion 50.0% (P＜0.05). 82.8% was the PER of VEGF in GC with lymph node metastasis, 54.5% without lymph node metastasis (P＜0.05).The PER of VEGF in GC accompanied by distant metastasis was 100%, higher than that without distant metastasis (71.0%, P＜0.05). PER of VEGF in pTNM Ⅰ+Ⅱ was 53.1%, in Ⅲ+Ⅳ 89.6% (P＜0.05). MVD correlated significantly with depth of invasion, lymph node metastasis,distant metastasis and pTNM stages (P＜0.05). There was correlationship between MVD and VEGF (P＜0.05).Conclusion VEGF expression upregulation and MVD contribute to the progression of gastric carcinoma.
