摘要 目的探讨人表皮生长因子受体2(HER2)、p-AKT、脂肪酸合成酶(FASN)及Ki-67在脑膜瘤组织中的表达及临床意义。方法采用免疫组织化学ElivisionTM法检测56例脑膜瘤和15例正常脑膜组织中HER2、p-AKT、FASN及Ki-67表达情况,并分析其表达与临床病理的关系。结果复发者HER2表达强度强于非复发者(P=0.036),WHOⅠ级复发者HER2表达强度强于WHOⅠ级非复发者(P=0.023)。HER2表达情况在不同脑膜瘤病理等级中差异无统计学意义。FASN、p-AKT脑膜瘤组表达强度高于正常脑膜组织(P=0.023,0.018),高级别脑膜瘤FASN、p-AKT表达强度均高于正常脑膜和较低级别脑膜瘤(P<0.05)。Ki-67指数复发者高于非复发者,随着脑膜瘤病理等级升高而显著升高(P<0.05)。HER2与FASN表达强度、FASN表达强度与p-AKT、Ki-67呈正相关(均P<0.05)。HER2中度阳性者术后无进展生存期明显短于阴性和弱阳性者,男性术后无进展生存期明显短于女性(P<0.05)。肿瘤WHO分级、HER2表达强度、Ki-67指数、骨侵犯和年龄与患者复发相关(P<0.05),骨侵犯和Ki-67指数是肿瘤复发的独立影响因素(P<0.01)。结论 HER2阳性表达程度有助于评估脑膜瘤术后无进展生存期,FASN和Ki-67高表达者脑膜瘤恶性程度较高或复发可能性较大,可作为脑膜瘤风险评估的重要指标。
