摘要 目的 探讨VEGF、EphB4受体与其配体EphrinB32在胃癌组织中的表达及其与血管生成的关系。方法 应用免疫组化SABC法检测93例胃癌和30例癌旁组织中VEGF,EphB4受体与其配体EphrinB2的表达及间质微血管密度(MVD)。结果 胃癌组织中肿瘤细胞、闻质新生血管的VEGF,EphB4与EphrinB2高度表达,VEGF阳性表达组的平均MVD值(为583±142)明显高于VEGF阴性表达组(为31.2±13.9.P=0.032),EphB4与EphrinB2阳性表达组的平均MVD值(分别为56.21±15.3和62.41±16.9)也明显高于EphB4与EphrinB32阴性表达组(分别为32.22±12.9和34.12±14.7.P=0.018和P=0.004),此外,VEGF还与EphB4/EphrinB2的阳性表达程度呈明显的正相关。结论 VEGF与EphB4/EphrinB2可以协同作用共同促进胃癌的血管生成。
