13日在京闭幕的第七届亚洲细胞治疗组织年会上,与会各国专家肯定了该方案对全球作出的贡献。

作为一种恶性血液疾病,白血病的死亡率占儿童恶性疾病死亡率的第一位、成人恶性疾病死亡率的第六位。治疗该病的最有效方法是进行造血干细胞移植即骨髓移植。然而,骨髓移植须在人类白细胞抗原(HLA)100%全相合的情况下进行,否则极易发生严重排异反应。但即使是同胞兄妹,全相合概率也仅有25%,而没有血缘关系的人群,全相合的概率只有十万分之一。因此,骨髓供体来源不足成为长期困扰白血病治疗领域的世界性难题。
从上世纪末开始,世界各国纷纷开展单倍体骨髓移植技术的临床研究。所谓单倍体移植,是指在骨髓干细胞半相合的情况下,也能让患者接受移植的技术。但这一技术刚推出时,接受移植的患者排异反应大,移植后生存率仅有20%。

1996年起,由北京大学血液病研究所所长黄晓军带领的团队开始自主探索粒细胞集落刺激因子在人体内抑制细胞排异功能的机制,在此基础上逐渐形成了中国原创的单倍体骨髓移植技术体系。如今,这种“人人有供体”的单倍体移植技术已成熟,其术后成功率达到70%,与全相合骨髓移植成功率相当,而英美等国同类移植技术的成功率仅40%。截至2015年底,通过该方案治愈的中国白血病患者已经超过5000人。

目前,该方案在法国、意大利、以色列、日本、韩国等国作为临床常规应用,覆盖全球50%以上的同类移植。2016年,该方案被世界骨髓移植协会正式命名为白血病治疗的“北京方案”,并推荐作为全球缺乏全相合供体的移植可靠方案。该方案还被写入国际骨髓移植权威教材,并被美国、英国等国骨髓移植协会相关指南引用。

“日本有20%的白血病患者找不到全相合的供体,采用中国方案治疗后,愈后效果良好。”世界细胞治疗组织副主席下坂皓洋说,中国在白血病治疗上的原创方案对世界影响深远。欧洲血液学会的前主席费比表示,中国方案为白血病骨髓移植技术制定了新的标准,全球数千万白血病患者都因此受益,“目前,欧洲、美国的患者采用中国治疗方案的比例大幅度上升。”

“饿死”癌细胞的药物IACS-10759已进入临床试验阶段

美国MD安德森癌症中心应用癌症科学研究所(IACS)对一个旨在“饿死”癌细胞的新药启动了首项临床研究,该药物编号为IACS-10759。该研究将招募急性髓系白血病病人参与研究,并得到了白血病和淋巴瘤学会治疗加速项目的350万美元支持。“我们非常高兴这项里程碑研究得到了白血病和淋巴瘤学会治疗加速项目的支持,我们希望能够尽快看到病人对IACS-10759这种药物产生良好的应答,就像我们在临床前模型观察

内部承载着骨髓细胞(概念艺术作品)的一根医用针的复合彩色扫描电子显微照片(SEM)。图片来源: STEVE GSCHMEISSNER Getty Images 一个美日合作团队发现,一种基础氨基酸在生成造血干细胞方面起着重要作用。科学家表示这一发现或为治疗血癌患者进行的化疗和放射治疗提供一种替代疗法。 人们通过食用蛋白质获得的氨基酸缬氨酸似乎对形成造血干细胞有着重要作用。近日发表于《科学》

Cancer Dis:白血病治疗新方法让癌基因变“乏力”

一些基因的重新激活会导致造血干细胞发生异常自我更新从而发生白血病,这些与自我更新有关的基因发生异常激活可能由DNA包装过程中的一些结构性修饰引起。最近一项研究发现有两种染色质调节因子能够介导这些表观遗传修饰的变化,并且白血病细胞非常依赖这两种因子。来自美国的科学家取得了上述研究进展,他们证明利用靶向药使这两种染色质调节因子失活可以破坏白血病细胞的自我更新程序使白血病细胞发生逆转重新变成正常血细胞。

Nature:揭示白血病细胞抵抗治疗新机制

一项新的研究揭示出白血病细胞如何能够在癌症治疗中存活下来,这提示着人们有可能阻止它们进一步发展。 白血病是血癌,而且具有比较高的癌症死亡率。这部分上是因为存在较高的复发率,这是因为一些白血病细胞在初始治疗时能够存活下来。这些存活的细胞经常抵抗癌症治疗,从而允许血癌扩散和变得致命性。 这些抵抗治疗的白血病细胞如何在初始化疗时存活下来仍未得到充分了解。一种流行的理论是它们潜藏在骨髓内的特定微环境中
