Neuro-Oncology:大脑体积能够预测脑癌风险?

2018-11-11 佚名 中国生物技术网

最近一项研究表明,拥有一个更大的大脑可能会使人面临罹患恶性脑癌的风险。研究人员认为,这或许是由于涉及大量脑细胞所致。

最近一项研究表明,拥有一个更大的大脑可能会使人面临罹患恶性脑癌的风险。研究人员认为,这或许是由于涉及大量脑细胞所致。

根据目前的估计,今年美国将有23880名成年人被确诊患上中枢神经系统肿瘤,其中高达90%的病例为脑肿瘤。

胶质瘤是一种常见类型的脑肿瘤,它起源于神经胶质细胞,即控制和支持神经元的非神经元脑细胞。神经胶质瘤占所有脑肿瘤的33%。它通常有几种类型,其中一些比较罕见,但却比其他的神经胶质瘤更具威胁。

对于哪些因素会增加神经胶质瘤的风险,我们知之甚少。因为尽管吸烟等生活方式因素在很多其他癌症的风险中扮演重要角色,但是对脑肿瘤却没有那么大影响。

然而,一些研究认为,拥有更多干细胞可以分裂的组织可能会增加患癌症的风险。这可能完全是基于细胞分裂时产生突变的统计学机率更高。

为此,挪威科技大学的Even Hovig Fyllingen博士及其同事们推测,大脑的体积或能够预测高级别神经胶质瘤的风险,这是神经胶质瘤的最晚期和最具攻击性的类型。

Fyllingen博士解释这项研究的动机时说:“有些研究表明,不同器官的体积是癌症发展的重要因素之一。比如,胸部更大的女性患乳腺癌风险更高。我们想知道脑瘤是否也遵循这种规律。”该研究已发表《Neuro-Oncology》上。

大脑体积和神经胶质瘤之间的关联

在该研究中,研究人员对124名患有高级别胶质瘤患者的颅内容量进行了测试,并与995名普通人的颅内容量进行比较。

研究人员获取了Nord-Trndelag健康研究的数据。这是一项大型研究,分析了成千上万名挪威人的生活方式、健康记录和血液样本,试图理解为什么有些人比其他人更容易患某些疾病。

在这项研究中,Fyllingen博士及其团队使用核磁共振成像扫描和三维大脑模型测量了参与者的颅内容量。然后他们利用二项logistic回归模型分析了颅内容积和性别对一个人患高级别神经胶质瘤的影响。

脑体积大的女性尤其面临风险

总体来看,该研究发现颅内容量与高级别神经胶质瘤之间存在强相关性。

Fyllingen博士解释说:“这项分析还显示,男性比女性更容易患脑肿瘤。男性的大脑比女性大,因为男性的体型通常都比较大。”

他解释说:“但这并不意味着男人更聪明,但是他们需要更多的大脑细胞来控制更大的身体。对于动物来说也是如此,体型更大的动物,它们的心脏、肺以及大脑等器官也更大。”

然而,这项研究还发现,颅内容量大的女性患脑瘤的风险要高于颅内容量大的男性。

Fyllingen博士总结说:“患脑癌的男性比女性多70%,但是当我们修正了头部大小之后,这个数字对女性就不那么有利了。大脑体积大的女性面临的风险尤其高。我不知道这是为什么。”

在修正了颅内容量之后,女性患高级别神经胶质瘤的风险更高。神经胶质瘤的发生与大脑体积有关,很大程度上可能是因为面临风险的细胞数量更多。”
