Watson走进14家肿瘤中心,助力医生确定更佳治疗方案

IBM的Watson部门日前宣布,来自美国和加拿大的14家肿瘤中心将部署沃森(Watson)计算机系统,根据患者的肿瘤基因选择适当的治疗方案。预示着人工智能机器人快速渗入医疗领域。

卢卡斯·沃特曼(Lukas Wartman)医生刚刚加入到利用基因学对抗癌症的大军中。沃特曼是圣路易斯华盛顿大学癌症基因学副主任,之前患上了急性淋巴细胞白血病



当所有治疗方案都尝试之后,沃特曼的同事希望利用DNA和RNA疗法来帮助他获得新生。这是一个艰苦卓绝的过程,经过多名研究人员数月的努力,沃特曼的病情终于好转。

如今,沃特曼加入到一个利用基因学对抗癌症的项目中,该项目旨在让更多的癌症患者获得DNA测序。华盛顿大学基因研究所是与IBM合作的14家大型癌症研究所之一,利用IBM沃森人工智能系统将患者的基因数据与癌症基因数据库和每一份关于癌症基因学的科学报告相对比。通过IBM沃森计算系统,几分钟就可以处理完毕通常一个专家团队通常需要几个小时或几天来处理的数据。

沃特曼说:“到目前为止,我还不知道其他哪个平台具有如此强大的计算能力,在其他研究中我也从来没见过。”

与14家大型癌症研究所合作也只是IBM将沃森系统引入医疗保健市场所做努力的一部分。除此之外,一个月前,IBM刚刚宣布了与美敦力(Medtronic)、强生和苹果等公司合作。上周,IBM、苹果和保险公司Japan Post又宣布一项合作协议,致力于提高老年人的生活质量。

通过此次与14家大型癌症研究所合作,IBM进入了已经十分拥挤的DNA测序和分析市场。当前,该市场主要竞争对手包括Foundation Medicine、NantHealth和Flatiron Health等。

NantHealth产品既能对患者DNA和蛋白质进行测序,也能对这些数据进行分析,并与患者医疗记录进行交互。而IBM则不同,主要专注于为提供基因测序服务的研究机构提供数据分析服务。

此次与IBM合作的14家肿瘤研究所分别为:芝加哥安妮和罗伯特·卢里儿童医院、BC Cancer Agency、希望之城(City of Hope)、 克利夫兰医学中心、杜克肿瘤研究所、弗莱德和帕梅拉巴菲特肿瘤中心、圣路易斯华盛顿大学麦克唐奈基因组研究所、纽约基因组中心、斯坦福健康(Sanford Health)、勘萨斯大学肿瘤中心、北卡罗来纳大学Lineberger肿瘤中心、南加州大学应用分子医学中心、华盛顿大学医学中心和耶鲁肿瘤中心

通过此次合作,IBM希望沃森系统能基于所处理的基因信息来选择治疗方案,从而取代当前 “肿瘤委员会”(tumor board)用药决定的模式。“肿瘤委员会”是肿瘤治疗实践中建立的一种类似会诊的治疗模式,拥有不同医疗专业技能的医生,如手术外科医师、药剂师等聚集在一起,成立针对某个病例的肿瘤委员会,讨论疑难、少见肿瘤病例的诊断和治疗,制定合理的诊断方法和治疗措施。

北卡罗来纳大学Lineberger肿瘤中心主任诺曼·夏普莱斯(Norman Sharpless)称:“肿瘤委员会的报告结果没有弹性,并不完美。随着任务量的加剧,这种模式也不再可行,我们需要像沃森这样的计算系统。”

虽然如此,夏普莱斯最初对沃森系统还是持谨慎态度,他希望能看到更多的证据。他表示,将密切关注北卡罗来纳大学分析的患者,看看“肿瘤委员会”和沃森系统究竟有多大程度的一致。

IBM沃森医疗部门副总裁史蒂夫·哈维(Steve Harvey)称,其他肿瘤研究中心也要求创建这样的研究报告,并以各研究中心同意的方式对患者身份进行匿名处理。最终,这些数据将属于患者本人。

但是,根据DNA测序结果来选择治疗方案究竟能在多大程度上帮助患者还是个未知数。这种方法确实挽救了一些患者的生命,但至少目前还不多见。此外,沃森系统也需要被进一步证明。此次IBM能与14家肿瘤研究中心签署合作协议确实令人印象深刻,但在医疗保健市场,沃森还是一项尚未被证明的技术。

沃特曼就是最好的例子,虽然治疗起了作用,但仍不是一个完美的解决方案。他进行了第二次骨髓移植,并患上了移植物抗宿主病,即他的新骨髓和他的身体相互攻击对方。沃特曼说:“目前这些问题大部分是可管理的,我还在全职工作,但不能100%投入。”
