像Ryder这样的年幼癌症患者家属相信,这一突破将改变生活。

目前,医学专家警告称,在现行医疗指导方针下,大量病例正被完全漏掉。

在众多受惠患儿中,Ryder是一个成功的案例。他在仅10个月大时就被诊断出患有侵袭性脑肿瘤,在勇敢忍受了数年痛苦治疗后,如今终于恢复健康。

对于Ryder的母亲Kelly来说,这个诊断结果虽令人揪心,却并不意外,因为她有着沉重的脑肿瘤家族史。

据Kelly回忆,多年前她的姨妈就死于脑肿瘤,但受限于当时的医疗技术,一直无法找到病因。

如今,随着技术进步,医生终于锁定了Ryder病案中的遗传诱因。Kelly感慨道,得知存在基因联系且不幸遗传给孩子时,她感到非常震惊。

儿童癌症研究所(CCI)的这项新研究,详细分析了约500名年幼患者。结果显示,每六人中就有一人出生时便带有这种特定的基因变化。

CCI的研究员Noemi Fuentes-Bolanos解释称,这种DNA变化会导致基因无法正常运作。她指出,临床发现带病基因的比例远超预期,这意味着为患儿找到精准治疗方案的可能性也随之提高。

然而,研究团队指出,由于现行的传统临床标准覆盖面过窄,一半符合条件的病例会被漏掉。基于这一现状,该团队强烈呼吁政府和医疗机构扩大基因检测的适用范围。

Ryder的父亲Alan对这一医学突破寄予厚望。他坚信,能够精确锁定癌症与基因之间的联系,将彻底改变无数正面临类似绝境的家庭的未来。
