(Press-News.org) A team led by investigators at Mass General Brigham and Dana-Farber Cancer Institute has developed and validated an artificial intelligence (AI)–based noninvasive tool that can predict the likelihood that a patient’s oropharyngeal cancer—a type of head and neck cancer that develops in the throat—will spread, thereby signaling which patients should receive aggressive treatment. The research is published in Journal of Clinical Oncology.
“Our tool may help identify which patients should receive multiple interventions or would be ideal candidates for clinical trials of intensive strategies such as immunotherapy or additional chemotherapy,” said senior author Benjamin Kann, MD, of the Artificial Intelligence in Medicine (AIM) Program at Mass General Brigham and a radiation oncologist at Dana-Farber Cancer Institute and Brigham and Women’s Hospital. “Our tool can also help identify which patients should undergo de-intensification of treatment, such as surgery alone.”
Treatments for oropharyngeal cancer, including combinations of surgery, radiation therapy, and chemotherapy, can be difficult to tolerate and may have lasting negative effects. Therefore, it’s important to identify subgroups of patients who may benefit from less or more intensive treatment approaches. One way to accomplish this involves assessing whether the patient has pathologic extranodal extension (ENE), which occurs when cancer cells invade beyond the lymph node into surrounding tissue. Currently, ENE can only be definitively diagnosed by surgically removing and examining lymph nodes.
To provide a method to assess ENE before treatment decisions are made, Kann and colleagues developed an AI-based tool that can take imaging data from computed tomography scans and predict the number of lymph nodes with ENE, an indicator of a patient’s prognosis and likelihood of benefiting from intensified therapy. When the tool was applied to imaging scans from 1,733 patients with oropharyngeal carcinoma, the tool was able to predict uncontrolled cancer spread and worse patient survival. Integrating the AI’s assessment into established clinical risk predictors improved risk stratification, leading to more accurate predictions of survival and cancer spread in individual patients.
“The AI tool enables the prediction of number of lymph nodes with ENE, which could not be done before, and shows that it is a powerful, novel prognostic biomarker for oropharyngeal cancer that could be used to improve the current staging scheme and treatment planning,” said Kann.

RIVERSIDE, Calif. -- A study led by biomedical scientists at the University of California, Riverside, has shown for the first time that a father’s exposure to microplastics (MPs) can trigger metabolic dysfunctions in his offspring. The research, conducted using mouse models, highlights a previously unknown pathway through which environmental pollutants impact the health of future generations.
While MPs have already been detected in human reproductive systems, the study, published in the Journal of the Endocrine Society, is the first to bridge the gap between paternal ...

Oxford-led study estimates NHS spends around 3% of its primary and secondary care budget on the health impacts of heat and cold in England
Analysis of 4.37 million patient records in England finds resources asymmetrically impacted by winter cold and summer heat, with about 64% linked to common cold days while very hot days drive sharp same-day demand surges
A new University of Oxford-led study, published in The Lancet Planetary Health, is the first to link daily temperature data to health-care use and costs across primary and secondary care in England.

Since his postdoctoral days at MIT, Hang Yu, associate professor of materials science and engineering, has been wrestling with the challenge of creating a shape-memory ceramic that can be manufactured at scale without breaking. Now, in tandem with Ph.D. student Donnie Erb '15, M.S. '18 and postdoctoral researcher Nikhil Gotawala, he’s had a breakthrough.
Yu’s team has used an advanced manufacturing technique called additive friction stir deposition to embed functional ceramic particles into metal. The result? A strong, defect-free material that can phase-shift under stress to dissipate energy and, unlike normally brittle ceramics, can be 3D-printed in ...
As cities grow and natural habitats shrink, urban wildlife must adapt to rapidly changing environments. A new study published in Insect Science shows that the guts of urban-dwelling wild bees contain detailed microbial signatures that reflect both bee health and the quality of the surrounding environment, offering a powerful new tool for monitoring ecological well-being in cities.
Researchers at Xi’an Jiaotong-Liverpool University (XJTLU) used metagenomic sequencing of the solitary mason bee Osmia excavata to analyze dietary pollen, gut bacteria and viruses, ...
Older adults who live in economically disadvantaged neighborhoods spend significantly fewer days at home in the year after a fall-related hip fracture than those living in more affluent areas, according to a large national study published today in JAMA Network Open.
The study analyzed Medicare data from more than 52,000 older adults who experienced a hip fracture. Researchers found that people living in the most disadvantaged neighborhoods spent about 23 fewer days at home during the year after their injury compared with those in the least disadvantaged areas after considering individual factors such as age or chronic illnesses.

About The Study: Commercial autonomous vehicle (AV) availability and adoption are underway and could impact national road traffic injuries. In this simulation study, potential injury reductions in the U.S. were forecasted using several scenarios based on real-world data. The results of this study suggest that AV adoption may reduce expected injuries; however, predicted confidence intervals remain broad for the baseline injury forecast, and none of the scenarios reduced expected injuries outside of these bounds.

About The Study: In this serial cross-sectional study of nationally representative administrative data from 2016 to 2022, the rate of alcohol-related hospitalizations was stable while mortality, length of stay, and health care costs all increased. Preventive efforts are needed to improve outcomes and reduce health care spending by reducing population-level alcohol consumption and engaging patients in alcohol use disorder treatment before progression to alcohol-related hospitalizations.
