Nottingham, UK – In a monumental leap forward for oncology, scientists and medical professionals in Nottingham have unveiled a revolutionary ultra-rapid method for genetically diagnosing brain tumours. This groundbreaking innovation promises to slash the agonizing wait time for a definitive diagnosis from the current 6-8 weeks to an astonishing two hours, a change poised to profoundly improve care for thousands of patients across the UK each year.
The development, a testament to interdisciplinary collaboration, emerges from the combined expertise of scientists at the University of Nottingham and clinicians at Nottingham University Hospitals NHS Trust (NUH). Detailed in a seminal study published today in the prestigious journal Neuro-Oncology, this new approach marks a pivotal moment in the fight against one of the most aggressive and challenging forms of cancer.
The Unbearable Wait: Understanding the Traditional Pathway
For too long, the journey following a suspected brain tumour diagnosis has been fraught with uncertainty, anxiety, and critical delays. The current diagnostic protocol, while thorough, is inherently slow and emotionally taxing for patients and their families. This protracted timeline has not only intensified psychological distress but has also tragically postponed the initiation of crucial treatments, potentially diminishing their efficacy.
A Labyrinth of Uncertainty
The conventional pathway for a brain tumour diagnosis typically begins with an MRI scan, which identifies the presence of a mass. Following this initial discovery, patients engage in discussions with clinicians to explore the potential nature of the tumour. The next, often lengthy, step involves surgery to obtain a tissue sample. This sample is then sent to centralised analysis facilities, where it undergoes complex genetic tests to identify specific DNA abnormalities that dictate the tumour’s precise type and characteristics.
"Traditionally, the process of diagnosing brain tumours has been slow and expensive," explains Dr. Stuart Smith, a Neurosurgeon from the School of Medicine at the University of Nottingham and NUH. "Patients find waiting many weeks for results extremely difficult and this adds to the anxiety and worry at what is already a very difficult time."
This extensive waiting period, which can stretch to 6-8 weeks or even longer, has significant repercussions. Without a definitive diagnosis, clinicians are unable to inform patients about their specific tumour type, its prognosis, or the most effective course of treatment. This delay directly impacts the commencement of vital therapies such as radiotherapy and chemotherapy, which are time-sensitive and whose effectiveness can be compromised by prolonged waiting times. For patients facing aggressive brain cancers, where the average survival rate can be less than a year, every single day counts.
Historically, neuropathologists relied on visual examination of tissue specimens under a microscope to classify tumours. However, in recent years, the understanding of brain tumours has evolved significantly, recognizing the critical role of genetic and molecular abnormalities in defining tumour behaviour and guiding treatment. This shift towards genetic classification, while vastly improving diagnostic accuracy, has inadvertently introduced new bottlenecks due to the technological limitations and logistical challenges associated with processing these complex tests on a large scale. Centralised labs, while essential, often face backlogs, further exacerbating the diagnostic delay. The emotional toll on patients and their loved ones during this period of suspended animation is immense, as they grapple with the unknown, unable to plan or prepare for the difficult journey ahead.
Forging the Future: The Nottingham Innovation
Recognizing the urgent need to address these critical shortcomings, a dedicated team of experts in Nottingham embarked on a mission to redefine brain tumour diagnosis. Their efforts have culminated in the development of an ultra-rapid genetic diagnostic method that promises to eliminate these agonizing delays entirely.
A Collaborative Endeavour
At the heart of this transformative breakthrough lies a powerful collaboration between the scientific prowess of the University of Nottingham and the clinical expertise of Nottingham University Hospitals NHS Trust. Leading the charge on the scientific front is Professor Matt Loose, a distinguished biologist from the School of Life Sciences at the University of Nottingham. Professor Loose’s pioneering work laid the foundation for the new method by developing a sophisticated technique to sequence specific parts of human DNA at an unprecedented depth, utilizing portable sequencing devices from Oxford Nanopore Technologies.
"When we first were able to sequence an entire human genome in 2018, it took around five labs and six months to do," Professor Loose recounts, highlighting the dramatic progress. "This new method now allows us to choose the bits of DNA that we need to look at in order to answer specific questions, such as what type of tumour and how can it be treated."
The innovation leverages the power of nanopore sequencing, a cutting-edge technology that works by detecting changes in electrical current as single molecules of DNA pass through tiny protein pores (nanopores) embedded in a membrane. This allows for real-time analysis of DNA sequences. The Nottingham team further refined this process by developing a specialized software tool named ROBIN, which operates on P2 PromethION nanopore sequencers. ROBIN is designed to efficiently sequence multiple regions of DNA simultaneously, dramatically accelerating the entire diagnostic process.
The method’s key strength lies in its ability to selectively target and analyze specific regions of the human genome that are most relevant to brain tumour classification. This targeted approach, as opposed to sequencing the entire genome, significantly reduces the time and computational resources required. Crucially, the team focused on analyzing DNA methylation patterns. Methylation, a biochemical process where methyl groups are added to DNA molecules, acts as a molecular fingerprint that can accurately define the type and subtype of a brain tumour.
"Once we have a sample from a patient, we can now quickly extract the DNA and look at the different properties to give us the information we need," Professor Loose explains. "Methylation is the one we are most interested in early on in this instance because that defines the tumour type."
The practical application of this method is remarkably streamlined. Once a tumour sample is removed during surgery, it is immediately sent to the pathology lab for DNA extraction. From there, the extracted DNA is transferred to Professor Loose’s team for rapid sequencing and analysis using the ROBIN platform. This integrated workflow ensures that the diagnostic process begins almost instantaneously post-surgery, laying the groundwork for the unprecedented speed of results.
Unprecedented Success and Tangible Benefits
The efficacy and transformative potential of the new rapid diagnostic method have been rigorously tested and unequivocally proven through practical application.
Proving the Concept: The NUH Pilot
The collaborative team at Nottingham University Hospitals NHS Trust (NUH) put the new approach to the ultimate test during 50 brain tumour surgeries. The results were nothing short of remarkable, demonstrating a 100% success rate in delivering rapid, intraoperative diagnoses. Diagnostic results were consistently provided in under two hours from the time of surgery, with detailed tumour classifications available within minutes of sequencing. The platform’s capabilities extend further, enabling a fully integrated and comprehensive diagnosis within a mere 24 hours.
This incredible speed opens up a revolutionary possibility: providing critical diagnostic information to the surgeon during the operation itself. "This type of operation can be quite long, so potentially, a surgeon could be informed during surgery of the accurate diagnosis, which would then impact on the surgical strategy," notes Dr. Stuart Smith. The ability to make informed decisions mid-surgery, such as adjusting the extent of resection based on tumour aggressiveness, represents a paradigm shift in neurosurgical practice, potentially improving immediate patient outcomes and guiding subsequent treatment pathways more effectively.
Beyond Speed: Accuracy and Affordability
While speed is a primary benefit, the Nottingham method does not compromise on accuracy. Dr. Simon Paine, a Consultant Neuropathologist at NUH, emphatically states, "This new method of diagnosing brain tumours is going to be a game changer, it really is revolutionary. It not only increases the speed at which the results will be available, but the degree of accuracy of the diagnosis as well is incredible." The high success rate and detailed classification capabilities underscore the robustness and reliability of the platform.
Moreover, the innovation addresses another critical aspect of healthcare: cost-effectiveness. Professor Loose highlights that the new method is significantly cheaper than current diagnostic approaches. "Our calculations stand at around £450 per person, potentially less when scaled-up," he reveals. This cost reduction stems from the method’s ability to consolidate multiple separate tests – often four or five – into a single, comprehensive analysis. By streamlining the diagnostic process and extracting more information from one test, the system not only saves money but also delivers results precisely when patients need them most. This financial benefit, combined with the unparalleled speed and accuracy, positions the Nottingham method as a truly sustainable and scalable solution for national implementation.

"Now, with this new technology we can do more for patients because we can get answers so much more quickly which will have a much bigger influence on clinical decision making, in as little as two hours," he states. His words highlight the dual benefit: alleviating patient anxiety and empowering clinicians with timely, critical data. The prospect of intraoperative diagnosis is particularly exciting for surgeons, as it offers the unprecedented opportunity to tailor surgical strategies in real-time, potentially optimizing tumour removal and improving patient prognosis. This immediate feedback loop could fundamentally change how complex brain tumour surgeries are approached, moving towards even more precise and personalized interventions.
