UVA harnesses AI to improve brain cancer care

2025-08-07
(Press-News.org) University of Virginia School of Medicine scientists are tapping the power of artificial intelligence to enhance and accelerate treatment for glioblastoma, the deadliest brain cancer.

UVA researcher Bijoy Kundu, PhD, and colleagues are developing an AI imaging approach to distinguish between tumor progression and brain changes caused by tumor treatment. It now can take months to make that distinction, leaving doctors uncertain if the tumor is growing and stalling important care decisions.

Kundu’s AI approach is already outperforming the standard clinical option in initial testing. Put to the test in 26 glioblastoma patients immediately after treatment, the artificial intelligence was able to make the correct distinction 74% of the time.

“The goal of the project is to train on additional patient data and increase this accuracy by greater than 80% for clinical use,” said Kundu, of UVA Cancer Center, UVA Health’s Department of Radiology and Medical Imaging and UVA’s Department of Biomedical Engineering.

That could have real benefits for patients. “Early distinction would enable earlier treatment modifications for tumor recurrence in brain cancer patients,” said David Schiff, MD, part of UVA’s Departments of Neurology, Neurosurgery and Medicine. Schiff is also co-director of UVA Health’s Neuro-Oncology Center.

Better Glioblastoma Care

Glioblastoma makes up more than half of all primary brain tumors. It is a highly aggressive and fast-growing cancer – typical survival from diagnosis is only 15 months. That makes it extremely important that doctors act quickly. Doing so can extend survival time and improve patients’ quality of life.

Now, however, doctors must wait three to four months after treatment to assess the progression of the tumor. They do this using magnetic resonance imaging (MRI) or, in some cases, brain surgery.

Kundu’s approach combines MRI with another form of imaging, dynamic PET (positron emission tomography). This produces sophisticated, multidimensional views inside the brain that artificial intelligence can analyze – all without the need to cut inside the skull.

Kundu and his collaborators have received $90,000 from UVA’s Ivy Biomedical Innovation Fund to advance and refine their approach. They will use the money to improve the accuracy of their deep-learning algorithms, essentially teaching the AI to better distinguish between signs of tumor progression and the effects of chemotherapy and radiation therapy.

They hope their work will ultimately help doctors get the information they need sooner, improving care for patients with glioblastoma.

“We hope this work helps patients and families get answers faster. If our AI can give doctors more confidence earlier, it could mean quicker treatment decisions and better outcomes,” Kundu said. “Our goal is to give doctors better tools, so they can focus less on guesswork and more on care. We’re still in the early stages, but even now, our approach is showing real promise. We’re working toward a future where patients get clarity sooner, and where that clarity helps save lives.”

UVA's Cutting-Edge Cancer Research

Finding new ways to improve patient care is a core mission of both UVA Cancer Center and UVA’s Paul and Diane Manning Institute of Biotechnology. UVA Cancer Center is one of only 57 cancer centers in the country designated “comprehensive” by the National Cancer Institute for their exceptional patient care and cutting-edge cancer research.

The Manning Institute, meanwhile, has been launched to accelerate the development of new treatment and cures for the most challenging diseases. This will be complemented by a statewide clinical trials network that expands access to potential new treatments as they are developed and tested.

UVA’s Department of Biomedical Engineering is a joint program of the School of Medicine and the School of Engineering and Applied Science.

MIT imaging tech promises deepest looks yet into living brain tissue at single-cell resolution

2025-08-07
Both for research and medical purposes, researchers have spent decades pushing the limits of microscopy to produce ever deeper and sharper images of brain activity, not only in the cortex but also in regions underneath such as the hippocampus. In a new study, a team of MIT scientists and engineers demonstrates a new microscope system capable of peering exceptionally deep into brain tissues to detect the molecular activity of individual cells by using sound. “The major advance here is to enable us to image deeper at single-cell resolution,” ...

Maple compound offers new way to fight tooth decay

2025-08-07
Washington, D.C. — A new study in the journal Microbiology Spectrum highlights the potential of using a natural compound from maple to combat the bacteria responsible for tooth decay: Streptococcus mutans. The compound, epicatechin gallate, is a powerful and safe alternative to traditional plaque-fighting agents. Its natural abundance, affordability and lack of toxicity make it especially promising for inclusion in oral care products such as mouthwashes, offering a safer option for young children, who often accidentally swallow mouthwash. The new study emerged as an offshoot of research into natural compounds that ...

New European guidelines reshape MASLD care with clearer diagnosis and targeted therapies

2025-08-07
A new framework for diagnosis The 2024 European clinical practice guidelines introduce a pivotal terminology shift, replacing NAFLD (non-alcoholic fatty liver disease) with MASLD (metabolic dysfunction-associated steatotic liver disease) and NASH with MASH (metabolic dysfunction-associated steatohepatitis). This renaming is not just semantic—it provides a pathophysiologically grounded, inclusive classification system based on the presence of hepatic steatosis and at least one cardiometabolic risk factor. Importantly, MASLD is now grouped ...

Adjuvant chemotherapy improves survival in resected early-onset pancreatic cancer after neoadjuvant therapy

2025-08-07
Background and objectives The incidence of early-onset pancreatic cancer (EOPC) is rising, yet optimal treatment strategies remain unclear. While adjuvant chemotherapy (ACT) has shown survival benefits in pancreatic ductal adenocarcinoma, its specific role in EOPC patients following neoadjuvant chemotherapy (NACT) and surgery remains underexplored. This study aimed to assess the clinical benefit of ACT in EOPC patients after NACT. Methods This retrospective cohort study analyzed pancreatic ductal adenocarcinoma patients from the SEER database (2006–2019) who received NACT followed by curative resection. Propensity ...

Quantum freezing at room temperature

2025-08-07
What are the limits of quantum physics? This is a question that has been researched around the world for decades. If we want to make the properties of the quantum world technically usable, we need to understand whether objects that are significantly larger than atoms and molecules can also exhibit quantum phenomena. For example, small glass spheres with a diameter of one hundred nanometres can be examined – still over a thousand times smaller than a grain of sand, but huge by quantum standards. For years, attempts have been made to show the extent to which such spheres ...
