(Press-News.org) (Barcelona, Spain September 6, 2025, 5:45 p.m. CEST / UTC +2 ) — A new study presented at the International Association for the Study of Lung Cancer 2025 World Conference on Lung Cancer (WCLC) validates the use of Sybil, a deep learning artificial intelligence model, for predicting future lung cancer risk in a predominantly Black population.
The study, conducted by the University of Illinois Hospital & Clinics, (UI Health), the academic health enterprise of the University of Illinois Chicago (UIC), highlights Sybil’s strong performance in a real-world clinical setting with racially and socioeconomically diverse patients. The Sybil Implementation Consortium comprises UIC, Mass General Brigham, Baptist Memorial Health Care, Massachusetts Institute of Technology, and WellStar Health System.
While prior United States Sybil validations were conducted in cohorts that were more than 90% White, this new analysis focused on a population where 62% of participants identified as Non-Hispanic Black, 13% Hispanic, and 4% Asian. The model demonstrated high predictive accuracy for lung cancer risk up to six years after a single low-dose CT (LDCT) scan.
“This study confirms that Sybil performs well in a racially and socioeconomically diverse setting, supporting its broader utility for lung cancer screening,” said Mary Pasquinelli, lead author, nurse practitionerand the Director of the Lung Screening Program at UI Health and a member of the University of Illinois Cancer Center . “It shows promise as a tool for improving early detection and addressing disparities in lung cancer outcomes.”
Pasquinelli and her colleagues evaluated 2,092 baseline LDCTs from UI Health’s lung screening program between 2014 and 2024. Of these, 68 patients were diagnosed with lung cancer, with follow-up times ranging from 0 to 10.2 years, she reported
The study found that Sybil’s Area Under the Curve (AUC) performance for years one through six were as follows:
- 0.94 (1-year)
- 0.90 (2-year)
- 0.86 (3-year)
- 0.85 (4-year)
- 0.80 (5-year)
- 0.79 (6-year)
If a lung cancer screening model has an AUC of 0.94, that means there’s a 94% chance the model will correctly rank a randomly chosen patient who develops cancer in the future as higher risk than a randomly chosen patient who does not develop cancer in the near future.
She reported that the results remained strong when restricted to Black participants and after excluding cancers diagnosed within three months of screening.
According to Pasquinelli, the study affirms Sybil’s clinical generalizability and suggests that the model may be unbiased with respect to factors like race and ethnicity, demonstrating strong performance in underrepresented communities. The Sybil Implementation Consortium will now proceed with prospective clinical trials to integrate Sybil into real-world clinical workflows, she said.

New medication lowered hard-to-control high blood pressure in people with chronic kidney disease
2025-09-06
Research Highlights:
Results from the FigHTN Phase 2 clinical trial showed baxdrostat, a new medication that inhibits the production of the hormone aldosterone, lowered systolic blood pressure by about 5% when added to the existing medications taken by people with chronic kidney disease and who also have uncontrolled high blood pressure.
The analysis also found that baxdrostat lowered the loss of albumin in the urine, which is a marker of kidney and cardiovascular risk, by 55% compared to placebo, suggesting that this medication may help delay the progression of kidney disease .
These findings suggest the potential for baxdrostat to improve longer-term health outcomes like kidney and ...
Innovative oncolytic virus and immunotherapy combinations pave the way for advanced cancer treatment
2025-09-05
The integration of oncolytic viruses (OVs) with immunotherapy is reshaping the landscape of tumor treatment, offering new hope for patients. This cutting-edge approach harnesses the ability of OVs to selectively infect and destroy tumor cells, while simultaneously stimulating anti-tumor immune responses. The latest advancements in genetic engineering have further optimized these therapies, leading to improved clinical outcomes and enhanced patient quality of life.
By combining OVs with cellular immunotherapy, immune checkpoint inhibitors, cancer vaccines, cytokines, and bi- or tri-specific T cell engagers, researchers have developed innovative ...
New insights into energy metabolism and immune dynamics could transform head and neck cancer treatment
2025-09-05
Head and neck cancer remains a major global health challenge, ranking among the six most common cancers worldwide and claiming hundreds of thousands of lives each year. A growing body of evidence now points to an intricate connection between energy metabolism and immune regulation as a driving force behind the onset, progression, and treatment resistance of these cancers. The latest comprehensive review on this topic underscores the potential of targeting these intertwined processes to unlock more effective therapies.
Tumor cells in head and neck cancer exhibit profound metabolic reprogramming, altering the way they process glucose, lipids, and ...

New method calculates rate of gene expression to understand cell fate
2025-09-05
UNIVERSITY PARK, Pa. — Essentially all cells in an organism’s body have the same genetic blueprint, or genome, but the set of genes that are actively expressed at any given time in a cell determines what type of cell it will be and its function. How rapidly gene expression in a single cell changes over time can provide insight into how cells might become more specialized, but current measurement approaches are limited. A new method developed by researchers at Penn State and Yale University incorporates spatial information from the cell as well as data from cells processed at different times, improving researchers’ ability to understand the nuances of gene expression ...
Researchers quantify rate of essential evolutionary process in the ocean
2025-09-05
The movement of genetic material between organisms that aren’t directly related is a significant driver of evolution, especially among single-celled organisms like bacteria and archaea. A team led by researchers at Bigelow Laboratory for Ocean Sciences have now estimated that an average cell line acquires and retains roughly 13 percent of its genes every million years via this process of lateral gene transfer. That equates to about 250 genes swapped per liter of seawater every day.
The new study, recently published in The ISME Journal, provides the first quantitative analysis of gene transfer rates across an entire microbiome. It calls into question the strict classification ...

Using new blood biomarkers, USC researchers find Alzheimer’s disease trial eligibility differs among various populations
2025-09-05
Some of the populations with the highest risk for Alzheimer’s disease remain greatly underrepresented in clinical trials—and a new study helps explain why. Researchers from the Keck School of Medicine of USC found that participants from these high-risk groups are less likely to have elevated amyloid in the brain based on blood levels of p-tau217. Elevated amyloid is a requirement for clinical trials of Alzheimer’s disease treatments, and amyloid is known to accumulate in the brain years before any signs of cognitive decline.
The study, funded in part by the National Institutes of Health (NIH), builds on earlier research with similar findings, but leverages ...
Pioneering advances in in vivo CAR T cell production
2025-09-05
This review article highlights the transformative potential of in vivo CAR T cell therapy in addressing the limitations of traditional CAR T cell production. This innovative approach could revolutionize cancer treatment, offering a more efficient, scalable, and cost-effective alternative to conventional methods.
CAR T cell therapy has shown remarkable success in treating hematological malignancies; however, current production methods are laborious, time-consuming, and expensive. Traditional in vitro CAR T cell production typically requires 2–3 weeks and involves complex processes, including T cell isolation, activation, genetic modification, ...
