摘要 目的 :了解颅内肿瘤组织、瘤周脑组织和脑脊液中端粒酶活性的表达情况 ,探讨其临床意义。方法 :选 4 6例颅内肿瘤病人 (恶性 2 3例 ,良性 2 3例 ) ,术中取肿瘤组织和瘤周组织 ,术前 1~ 3d和术后 3~ 5d腰穿取脑脊液 (CSF) ,应用PCR -TRAP法检测其端粒酶活性 ,以 χ2 检验统计分析。结果 :恶性肿瘤组瘤组织端粒酶活性的阳性率为 95 .6 % (2 1/ 2 3) ,瘤周组织为 2 1.7% (5 / 2 3) ,术前CSF为 6 2 .5 % (10 / 16 ) ,术后CSF为 4 0 %(2 / 5 ) ;良性肿瘤组瘤组织端粒酶活性的阳性率为 6 5 % (15 / 2 3) ,瘤周组织为 2 1.7% (5 / 2 3) ,术前CSF为37.5 % (6 / 16 ) ,术后CSF为 0 (0 / 5 ) ;肿瘤全切后脑脊液端粒酶活性阳转阴率 87.5 % (7/ 8) ;恶性肿瘤瘤组织中端粒酶活性的阳性率明显高于良性肿瘤 (χ2 =4 .6 ,P <0 .0 5 )。结论 :颅内良性肿瘤和恶性肿瘤均有端粒酶活性的表达 ,其表达率后者明显高于前者 ;术前脑脊液中端粒酶活性的检测可用于脑肿瘤的临床诊断和鉴别诊断 ;瘤周组织和术前脑脊液中端粒酶活性的检测 ,尤其是术前术后CSF中端粒酶活性阳转阴有望成为评估肿瘤复发的指标。
