Lower invasiveness of papillary thyroid carcinoma associated with Hashimoto’s thyroiditis: evidence from AJCC 8th-edition stratification and a dose–response relationship with autoantibody titers
Background Hashimoto’s thyroiditis (HT) and papillary thyroid carcinoma (PTC) frequently coexist, but the precise impact of HT on PTC invasiveness — particularly across the strict American Joint Committee on Cancer (AJCC) 8th-edition extrathyroidal extension (ETE) categories — remains incompletely characterized.
