由桑格研究所领导的一支国际合作团队最近证明了一种可以在未来帮助癌症患者真正实现个体化治疗的新概念。这些发现能够用于为急性髓系白血病(AML)患者找到最佳的治疗选择。相关研究结果发表在国际学术期刊Nature Genetics上。

AML是一种由骨髓细胞形成的侵袭性血液癌症。该研究团队曾经报道有11种AML存在不同的基因特征。在这项最新研究中他们又介绍了如何利用病人的基因信息预测结果,帮助进行治疗选择。

研究人员利用1540名AML病人的数据构建了一个“知识库”,整合了每位病人的基因特征信息,治疗计划和治疗结果。借助这些信息该研究团队开发了一种工具用以展示如何通过知识库的数据为新患者提供有关治疗选择的个体化治疗信息。

对年轻的AML病人来说主要有两个治疗选择——干细胞移植和化疗。干细胞移植整体治愈率较高,但是每四名接受治疗的病人中就会有一人死于并发症,还有许多病人需要承受长期副作用。如何权衡利弊选择最合适的治疗方法对于病人和医生来说都很困难。而该研究表明这些好处和风险都可以针对每个病人的情况进行精确计算,保证病人获得个性化的治疗方案。

研究人员估计相比于目前的情况使用这种工具以后最高每三名病人中就会有一人获得不同的治疗方案。不过该工具目前只提供给用于研究的科学家们,在真正应用之前还需要进行进一步的检测。

该文章作者Dr. Moritz Gerstung表示:“长期以来癌症一直被当作一种复杂遗传疾病。我们的研究提供了一个很好的范例如何将详细的遗传和临床信息恰当地用于每位病人的临床治疗选择。我们只在一种白血病中进行了这种概念的检测,但是理论上来说,这种概念也可以用于其他难以进行治疗选择的癌症。我们的分析结果表明需要构建多达10000名病人的知识库来获得常规临床应用的准确性。”
