New Ultrasound-Driven Model Boosts Accuracy in Diagnosing Endometrial Malignancy: Study Shows

The key findings of the study were as follows:

• Women with malignant or pre-malignant findings had a significantly thicker endometrium (average 14.2 mm) than those with benign lesions (10.1 mm).
• Ultrasound abnormalities were more commonly observed among women in the positive group.
• Independent predictors of malignancy included increased endometrial thickness (OR 2.94), abnormal ultrasound features (OR 4.12), presence of diabetes (OR 1.98), and obesity with a BMI ≥ 30 kg/m² (OR 1.82).
• The predictive model showed strong diagnostic performance, achieving an area under the curve (AUC) of 0.81, reflecting good accuracy in identifying high-risk cases.

According to the researchers, incorporating clinical and imaging data enables a more holistic understanding of a patient’s risk profile. “This model provides a practical method for identifying high-risk postmenopausal women,” the authors noted, highlighting the potential to reduce unnecessary invasive tests while ensuring timely intervention for those who need it.

They also stressed the importance of future research to validate this model across broader populations and explore new imaging techniques that may further refine diagnostic capabilities.

By aligning with personalized medicine principles, the study marks a step forward in enhancing care pathways for postmenopausal women with endometrial abnormalities.
