【摘要】 本文比较分析了１８例神经母细胞瘤的ＤＮＡ含量、Ｎ－ｍｙｃ基因扩增、临床分期、原发部位等因素与预后的关系。结果表明，有Ｎ－ｍｙｃ基因扩增的死亡率（７／１０）明显高于无扩增的（１／８）；ＤＮＡ、含量增高与肿瘤的恶性度成正比；临床分期与Ｎ－ｍｙｃ基因扩增情况相结合与病死率的关系极为密切。更多还原

【Abstract】 In this study,18 children with neuroblastoma were analysed on the relation among DNA content,N- myc gene amplification and the clinical staging.The results reveal:the mortality of patients with N-myc gene amplification(7/10)was higher than those without N-myc gene amplification(1/8);DNA content was related to malignancy of the tumor.combination of N-myc gene amplification and the clinical staging kept close link with the prognosis.更多还原
