Abstract
腦瘤佔臺灣地區所有癌症死亡原因之1.25%,其五年存活率僅約20%。目前有關腦瘤的成因仍未明,已確認的危險因子僅有游離輻射一項。人類第二型乙醯轉移?(NAT2)參與許多致癌物的活化或解毒過程,其代謝速率有顯著的個體差異,一般以帶有一個以上野生型對偶基因(NAT2*4)者為rapid acetylator,其餘基因型稱為slow acetylator。NAT2和許多癌症有關,但和台灣地區腦瘤的相關則尚未有研究。 本研究主要目的為探討乙醯轉移?基因型的分布在腦瘤病患與未罹患癌症之配對對照組中的差異。次要目的為分析不同乙醯轉移?基因型的腦瘤病患其存活率、腫瘤型態、腫瘤分級之差異。 本研究比較27名腦瘤病患及27名正常對照組,以PCR-RFLP方式分析病患之腫瘤切片及對照組的週邊血液檢體,檢測NAT2*5、NAT2*6及NAT2*7,共三個allele。結果發現NAT2*7 allele在腦瘤病患組的比例明顯較對照組高,p=0.001,帶有NAT2*7 allele者罹患腦瘤之odds ratio為6.79(95%, CI 2.06-22.37);帶有NAT2*7 allele的病患中astrocytoma和glioblastoma multiforme的比例較高(p=0.016)。其他次要目的如存活、率腫瘤類型等則未發現有差異。因此,NAT2*7 allele與astrocytoma和glioblastoma multiforme之間的關聯值得進一步探討研究。
