Highlights
The 2025 ATA risk stratification system for papillary thyroid carcinoma (PTC) demonstrates significant reclassification patterns when applied to a real-world cohort of 670 patients. Low-risk classifications decreased by 22.2%, while intermediate and high-risk categories increased by 41.7% and 14.9% respectively. The newly defined “low-intermediate-risk” class represents a statistically distinct group with structural disease persistence risk falling between prior low-risk and intermediate-risk categories.
