Scientists have developed an “ultra-fast” test which can slash the time patients have to wait to find out which type of brain tumour they have.
Patients usually wait six to eight weeks to find out their type of brain tumour. But the new “game changer” tool, which assesses the DNA from a sample taken from the tumour, can achieve this in around two hours, experts found.
This means patients can start treatment faster, and the test may even help surgical teams while they are operating to remove tumours, they said.
Researchers from the UK’s University of Nottingham and Nottingham University Hospitals NHS Trust assessed the new test on 50 patients.

The research team, which publishing their findings in the medical journal Neuro-Oncology, said the new test was “in concordance with standard of care” for “90 per cent of cases”.
They said the new test can provide diagnostic results in under two hours from surgery, and detailed tumour classifications within minutes of sequencing.
Usually, medics have to send samples away to central analysis facilities for genetic analysis.
This long wait is “traumatic” for patients and can delay chemotherapy and radiotherapy, the experts said. But the new method, called Robin – rapid nanopore brain intraoperative classification – can potentially eliminate this delay, they added.

Professor Matt Loose, from the School of Life Sciences at the University of Nottingham, developed a method to sequence specific parts of human DNA at “higher depth” using Oxford Nanopore Technologies portable sequencing devices.
The team have now used this method to genetically test brain tumour samples.
“Not only is the test more accurate and quicker, but it is also cheaper,” Loose said.
Neurosurgeon Dr Stuart Smith, from the University’s School of Medicine and NUH, added: “Traditionally, the process of diagnosing brain tumours has been slow and expensive.
“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.”
[The new test] not only increases the speed at which the results will be available, but the degree of accuracy of the diagnosis as well is incredible
Dr Simon Paine, consultant neuropathologist
He said the test was so rapid that it could even help surgeons during any operation to assist with their “surgical strategy”.
Dr Simon Paine, a consultant neuropathologist at NUH, added: “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,” Paine said.
Dr Simon Newman, from The Brain Tumour Charity, said: “The delivery of an accurate diagnosis within hours of surgery will be transformative for all patients, ensuring rapid access to the optimal standard of care and – crucially – removing the uncertainty patients face when having to wait weeks for their diagnosis and prognosis.
“The potential to combine so many separate tests into one and deliver at a localised level is a game changer for driving equity of access to rapid and accurate molecular diagnosis.”

How to spot brain tumour symptoms, their treatment and the promising advances made in the fight against brain cancer

There are no lifestyle changes one can make to lower the risk of brain cancer, and there are various types of brain tumours. Some are more aggressive than others, cancer doctors say, but advances in drug therapies show promise. Photo: Shutterstock

Glioblastoma is the most aggressive glioma, says Dr Maverick Tsang, a specialist in clinical oncology at the Hong Kong Integrated Oncology Centre. Photo: Dr Maverick Tsang
