Tumours in which the cancerous cells infiltrate the surrounding healthy tissue are particularly difficult to treat and currently have a rather poor prognosis. An example of such a type of cancer is a glio-blastoma multiforme (GBM), the most common form of primary, malignant brain tumour, which afflicts around 2000 people per year in the UK alone. Despite recent improvements in treatment, this essentially remains incurable. Boron Neutron Capture Therapy (BNCT), the subject of this project, is a form of cancer radiotherapy and looks particularly well-suited to treating this type of tumour. In this, an isotope of boron, boron-10, is administered to the patient in such a way that it accumulates in the cancerous cells. Boron-10 is stable and harmless, until it reacts with thermal neutrons. The products of this reaction destroy the cancerous cells in which they are created. The treatment then proceeds by passing a beam of neutrons though the tumour once the boron-10 has accumulated, thereby destroying most of the cancer cells. The remainder can be treated with standard radiotherapy. Recent studies of this therapy in Japan have shown very promising results. The aim of this project is to create a technology driver for a BNCT facility in Birmingham University and the Queen Elizabeth Hospital in Birmingham. This will be done in two phases: the first determining the changes required to an existing facility to deliver this and the second implementing them. Once complete, this will be used to undertake clinical trials of the therapy to demonstrate its effectiveness for a number of types of cancer. At a later stage, this driver will also be used to design a BNCT facility that can be constructed commercially and used in other large radiotherapy departments in the UK and elsewhere.

癌细胞浸润周围健康组织的肿瘤特别难以治疗，目前预后相当差。此类癌症的一个例子是多形性胶质母细胞瘤 (GBM)，它是最常见的原发性恶性脑肿瘤，仅在英国每年就有约 2000 人受到这种癌症的影响。尽管最近治疗方法有所改进，但这基本上仍然无法治愈。该项目的主题硼中子捕获疗法（BNCT）是癌症放射疗法的一种形式，看起来特别适合治疗此类肿瘤。在此过程中，向患者施用硼同位素硼 10，使其在癌细胞中积聚。硼 10 是稳定且无害的，直到它与热中子发生反应。该反应的产物会破坏产生它们的癌细胞。一旦硼 10 积累起来，治疗就会通过将中子束穿过肿瘤来进行，从而破坏大部分癌细胞。其余的可以用标准放射疗法治疗。日本最近对这种疗法的研究显示出非常有希望的结果。该项目的目的是为伯明翰大学和伯明翰伊丽莎白女王医院的 BNCT 设施创建技术驱动程序。这将分两个阶段完成：第一个阶段确定现有设施所需的更改以实现此目的，第二个阶段实施这些更改。一旦完成，这将用于进行该疗法的临床试验，以证明其对多种癌症的有效性。在稍后阶段，该驱动程序还将用于设计 BNCT 设施，该设施可以商业化建造并用于英国和其他地方的其他大型放射治疗部门。
