Autoimmune thyroiditis incidence in a large population-based study in northeastern Italy.

Purpose: An improvement in iodine status in the Veneto region (Italy) in the last decade has been documented. Our aim was to estimate the incidence of autoimmune thyroiditis (AT) in this region over the period 2012-2022.

Methods: A retrospective population-based study conducted in Veneto using the population registry and administrative health databases.

Tumor Grade and Molecular Characteristics Associated with Survival in Sporadic Medullary Thyroid Carcinoma.

The International Medullary Thyroid Carcinoma Grading System (IMTCGS) divides medullary thyroid carcinoma (MTC) into two categories, high- and low-grade tumors, which has a profound impact on patient outcomes. The aim of this study was to explore the association between IMTCGS grading, clinical data, and molecular status in sporadic MTC. A retrospective cohort study was performed on consecutive sporadic MTCs from patients undergoing initial surgery between January 2000 and January 2022 at the Padua Endocrine Surgery Unit.
