凋亡抑制基因Survivin在颅咽管瘤中的表达及意义

目的 研究Survivin基因在颅咽管瘤中的表达及意义.方法 选取四川大学华西医院2000年至2005年颅咽管瘤石蜡标本50例,采用免疫组化和计算机数字图像分析技术定量分析Survivin的表达情况.结果 所有颅咽管瘤标本均发现有Survivin表达,而正常脑组织未见表达.造釉细胞型的表达强于鳞形乳头型(P=0.036),男性患者的表达强于女性患者(P=0.002),≤16岁患者的表达强于>16岁患者(P=0.002),复发组的表达强于非复发组(P=0.011),Survivin在颅咽管瘤不同肿瘤性质(P=0.057)及不同病程中(P=0.083)未显示统计学差异.结论 Survivin的表达可作为评估肿瘤复发的有意义的参考指标.

Expression and significance of apoptotie suppressor gene survivin in craniopharyngioma

Objective To study the expression and significance of survivin,an apoptotic suppressor gene,in craniopharyngioma. Methods Fifty specimens were collected from patients with craniopharyngioma admitted in West China Hospital of Sichuan University from 2000 to 2005. By using immunohistocbemistry (S-P) method, the expression of survivin in craniopharyngioma was detected. The results were analyzed quantitatively by using digital image analysis. Results Survivin positive expression was observed in craniopharyngioma but not in normal brain tis-sue. There was more expression of survivin in adamantinomatous craniopharyngiomas than in squamous papillary types( P = 0.036 ) , in male than in female (P = 0.002 ), in children ≤ 16 years than in adults > 16 years, and in re-current group than in non-recurrent group( P = 0.011 ). There was no significant difference among different properties of craniopharyngioma ( P = 0. 057 ), and different courses of disease ( P = 0. 083 ). Conclusions Survivin may be considered as a significant index for assessment of tumor recurrence.
