摘要 目的探讨PTEN、VEGF和Ki-67在人脑胶质瘤中的表达及其与肿瘤恶性程度的关系。方法应用免疫组织化学方法检测60例脑胶质瘤和10例脑外伤内减压脑组织中PTEN、VEGF和Ki-67的表达,并与肿瘤的恶性程度进行分析。结果 PTEN、VEGF和Ki-67在正常脑组织和脑胶质瘤组织中表达差别有意义(P<0.05);在高分化脑胶质瘤组(I-II级)和低分化恶性胶质瘤组(III-IV级)表达差别有意义(P<0.05);PTEN在正常脑组织中高表达,随脑胶质瘤恶性程度的增高,PTEN表达强度下降;VEGF和Ki-67在正常脑组织中表达不明显,随肿瘤恶性程度增高表达强度上升。结论 PTEN表达的降低在脑胶质瘤中的发生、发展过程中起作用;VEGF和Ki-67的表达反应了肿瘤的血管增殖和分化的一般规律;三者结合检测有利于判断脑胶质瘤的生物学行为和评估预后。
