Artificial intelligence improves risk stratification in oropharyngeal cancer

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.

CT-based quantification of tumor fibrosis guides chemotherapy in pancreatic cancer

On October 3, 2025, a multicenter team from Shenzhen University, Xiangya Hospital of Central South University, Zhujiang Hospital of Southern Medical University, Wuxi People's Hospital Affiliated to Nanjing Medical University, among others jointly reported a novel noninvasive method for quantifying tumor fibrosis based on preoperative enhanced CT.

Simple blood test maps hidden Alzheimer’s disease changes

This population-based study used plasma pTau217 to estimate how common Alzheimer’s disease neuropathological changes are across age and cognitive status in a Norwegian community cohort. Prevalence rose steeply with age and was strongly associated with APOE ε4 genotype, education level, and kidney function, with implications for future use of blood biomarkers in clinical practice.

Breakthrough in imaging speed moves portable stroke diagnosis closer to reality

When someone walks into an emergency room with symptoms of a stroke, every second matters. But today, diagnosing the type of stroke, the life-or-death distinction between a clot and a bleed, requires large, stationary machines like CT scanners that may not be available everywhere.

Poor lung gas exchange may help explain lingering brain symptoms in Long COVID

This study found that people with Long COVID more than two years after infection showed normal lung tests and brain structure, yet reported significant sleep and cognitive symptoms. Subtle correlations revealed that poorer lung gas exchange was linked with higher brain perfusion, worse sleep, and weaker executive function, suggesting a possible lung–brain connection.

Study offers new insights on patient care and lung cancer surveillance rates

Despite recommendations for posttreatment surveillance in lung cancer patients, there is wide variability in the follow-up care that lung cancer patients receive. A recent study, led by senior author Leah Backhus, MD, MPH, Professor of Cardiothoracic Surgery (Thoracic Surgery) in the Stanford Department of Cardiothoracic Surgery, offers new insights on patient care and lung cancer surveillance rates.
