(Press-News.org) A research team led by Prof. Hai Li from the Hefei Institutes of Physical Science, Chinese Academy of Sciences, has become the first to systematically explore how large language models (LLMs) can assist in predicting liver cancer treatment responses—offering a new path toward AI-powered precision medicine.
The study was published in the Journal of Medical Systems.
Hepatocellular carcinoma (HCC) is one of the most common and deadly cancers worldwide. For patients with advanced HCC, combination therapies such as immune checkpoint inhibitors and targeted treatments offer some hope, but only around 30% of patients respond effectively. This makes accurate prediction of treatment response a critical unmet need in personalized oncology.
In this study, the team evaluated the performance of leading LLMs—GPT-4, GPT-4o, Google Gemini, and DeepSeek—in predicting treatment outcomes using zero-shot learning. This means the models were not specifically trained on liver cancer data beforehand. The dataset included clinical and imaging information from 186 inoperable HCC patients.
To enhance performance, the researchers tested various decision-making strategies, such as voting rules and logical combinations, and created a hybrid model named Gemini-GPT.
The Gemini-GPT model demonstrated predictive accuracy on par with senior doctors (15+ years of experience), while outperforming junior and mid-level clinicians in both speed and accuracy. It consistently produced stable results across various treatment types and disease stages, and proved especially reliable in identifying patients likely to benefit from therapy—often showing greater consistency than human doctors.
Applying simple logical strategies further improved its practical utility in clinical settings.
"This research shows how AI can help doctors make better decisions and offer more personalized treatment for cancer patients," said Prof. LI Hai.
The study marks an important step toward trustworthy AI integration in real-world oncology, demonstrating that LLMs can do more than language—they can reason, predict, and support critical medical decisions.

Tracking insect and bug health in a heartbeat from a digital camera
2025-07-10
In a world-first pilot study, researchers from the University of South Australia have used video footage of insects to extract their heart rates without touching or disturbing them.
The innovation, published in the Archives of Insect Biochemistry and Physiology, could transform how scientists monitor the health and stress levels of arthropods, that account for more than 80% of animal species.
Taking footage from smartphones, social media videos and digital cameras, the researchers used sophisticated signal processing methods to monitor the heart activity of ants, bees, caterpillars, spiders, grasshoppers and stick insects.
Unlike mammals, arthropods have an ...
'Talking fish' not heard by conservation policies, SFU study warns
2025-07-10
More than a thousand fish species use sounds to exchange information, attract mates, and avoid predators through hums, grunts, clicks, and bubbles. Yet, the vital role of fish sounds—and the impact of noise pollution on the fishes that produce them—are left out of critical conservation policy, says study led by marine ecologists at Simon Fraser University.
The ocean is filled with the bustling sounds of daily marine life, including the sounds made by soniferous fish species. These sounds aren’t merely passive sounds—soniferous fishes produce sound themselves, like a whale ‘singing’ through vocalizations, says Kieran ...
Thirty years of research shows increased resistance in fungi
2025-07-09
Fungi are increasingly resistant to antifungals, and the variation in resistance has significantly increased. This is evident from the analysis of more than 12,000 lung samples collected over thirty years in Dutch hospitals. In addition, a resistant infection in a patient almost always consists of different fungal strains, making treatment more challenging. This study by Radboud university medical center and public health institute RIVM has been published in The Lancet Microbe.
When consultant microbiologist Paul Verweij and his team began collecting Aspergillus fumigatus isolates from patients’ lungs in 1994, they did not ...
Junk food ‘avoids advertising regulation’ with top level UK sports sponsorship
2025-07-09
Junk food firms have more than 90 current sponsorship deals within top UK sports amid growing concerns over their impact on public health, finds an investigation published by The BMJ today.
Brands including Cadbury, Pepsi, KP Snacks, Walkers, Kellogg’s, Red Bull, and Monster are among those with ongoing partnerships with sporting stars, top flight teams, or official governing bodies.
They include deals with top men’s and women’s football stars Cole Palmer, Bukayo Saka, Leah Williamson, and Lauren James, England Cricket captain ...
Banking on AI while committed to net zero is ‘magical thinking’, claims report on energy costs of big tech
2025-07-09
By 2040, the energy demands of the tech industry could be up to 25 times higher than today, with unchecked growth of data centres driven by AI expected to create surges in electricity consumption that will strain power grids and accelerate carbon emissions.
This is according to a new report from the University of Cambridge’s Minderoo Centre for Technology and Democracy, which suggests that even the most conservative estimate for big tech’s energy needs will see a five-fold increase over the next 15 years.

Ancient river systems reveal Mars was wetter than we thought

The discovery of more than 15,000 kilometres of ancient riverbeds on Mars suggests that the Red Planet may once have been much wetter than previously thought.
Researchers looked at fluvial sinuous ridges, also known as inverted channels, across Noachis Terra – a region in Mars' southern highlands. These are believed to have formed when sediment deposited by rivers hardened ...

The psychological and neurological parallels between sports fandom and religious devotion
2025-07-09
An in-depth exploration of the psychology of sports fandom has revealed striking similarities between the neurological and psychological patterns of devoted sports fans and religious dedication.
These similarities are explored in new book The Psychology of Sports Fans, which demonstrates how, for nearly five billion people globally, sport fulfils fundamental psychological needs for belonging, identity, and meaning.
The comprehensive analysis shows that sports fandom stems from evolutionarily ingrained tendencies which enhance social unity and therefore survival.
Professor Aaron C. T. Smith explains: “Our ...
Agricultural liming in the US is a large CO2 sink, say researchers
2025-07-09
Adding lime to agricultural soils can remove CO2 from the atmosphere, rather than cause CO2 emissions, claims new research.
The findings, based on over 100 years of data from the Mississippi River basin and detailed computer modelling, run counter to international guidelines on reducing agricultural emissions.
The research is presented today [Thursday 10 July] at the Goldschmidt Conference in Prague.
The team, from the Yale Centre for Natural Carbon Capture at Yale University, show that the addition of acidity, in the form of atmospheric pollution and fertilisers, is the main driver for CO2 emissions from soils. By calculating emissions based on acid inputs, they show how ...
Seaside more likely to make us nostalgic than green places, study finds
2025-07-09
People in the UK and US are more likely to feel nostalgic towards places by the sea, lakes or rivers than they are towards fields, forests and mountains, according to new research. The study suggests that coastlines may have the optimal visual properties to make us feel positive emotions, and argues that ‘place nostalgia’ offers significant psychological benefits.
Seaside and oceanside spots account for over a quarter of nostalgic places identified by UK residents (26%) and one-fifth (20%) of US residents in the University of Cambridge-led study.
Rivers and lakes raise the figure to around a third (35% UK; 30% US). ...
