【摘要】 目的探讨血管内皮生长因子(VEGF)在老年进展期胃癌的表达及其与预后的关系。方法选择60例老年进展期胃癌患者为观察组,同期32例健康体检者为对照组。应用免疫组织化学法检测胃癌组织与正常胃黏膜组织VEGF及微血管密度(MVD)的表达情况,并对MVD、VEGF表达水平与患者预后进行分析。结果观察组胃癌组织VEGF及MVD阳性率显著高于对照组(P<0.01);观察组不同肿瘤TNM分期和有无淋巴结转移癌患者中VEGF及MVD表达差异有统计学意义(P<0.01);VEGF阳性者3年生存率和5年生存率显著低于VEGF阴性胃癌患者(P<0.01)。结论 VEGF表达与血管生成和肿瘤进展、淋巴结转移密切相关,可作为判断老年进展胃癌预后的重要参考指标。更多还原

【Abstract】 Objective To explore the relationship between the expression of vascular endothelial growth factor (VEGF) and prognostic evaluation in patients with elderly advanced gastric cancer. Methods Sixty patients of elderly advanced gastric cancer were selected as the study group, and 32 healthy individuals were enrolled as the control group. Immunohistochemical study was performed in the two groups to investigate the expression of VEGF and microvessel density (MVD). The relationship between the levels of VEGF and MVD and prognosis was analyzed. Results The positive rates of VEGF and MVD were much higher in the study group than the control group (P<0.01); There was statistically significant difference in the expression of MVD and VEGF in different TNM stages and lymphatic metastasis (P<0.05). The three-year survival rate and five-year survival rate were significantly lower in patients with positive expression of VEGF than patients with negative expression of VEGF. Conclusion The expression of VEGF is closely associated with angiogenesis, tumor growth and tumor metastasis. VEGF can be the prognostic discriminators in prostate cancer.更多还原
