目的:通過檢測髓母細胞瘤(Medulloblastoma)中凋亡抑制蛋白(survivin)的表達情況,探討它的臨床意義,為髓母細胞瘤的治療尋求新的思路。方法:對50例髓母細胞瘤及10例正常腦組織石蠟切片行免疫組化檢測,通過對survivin蛋白在髓母細胞瘤患者與正常腦組織中的表達差異,并運用相關(guān)統(tǒng)計分析方法分析它在不同性別、年齡段、腫瘤大小、病理類型、臨床分期的表達差異及其與預后的相關(guān)性。結(jié)果:(1)髓母細胞瘤中survivin蛋白陽性表達率為72%,明顯高于正常腦組織的陽性表達率0%,二者表達差異明顯(P lt;0.01);亞組分析發(fā)現(xiàn)在survivin蛋白陽性組(n=36)和陰性組(n=14)病例中,性別分布、腫瘤部位、腫瘤大小、病理分型等因素在兩者間無明顯差別(P gt;0.05),而年齡及TM臨床分期在兩組間差異顯著(P分別為0.044和0.027)。(2)survivin陽性患者預后與和陰性組相比差異顯著(P=0.001)。結(jié)論:survivin可能參與了對髓母細胞瘤細胞凋亡的調(diào)控,并對髓母細胞瘤的發(fā)生發(fā)展可能起著重要作用。由于survivin蛋白表達與髓母細胞瘤患者年齡、臨床分期及預后等也密切相關(guān),可作為判斷病情和評價預后的指標。
