A Relook at the T Stage of Differentiated Thyroid Carcinoma with a Focus on Gross Extrathyroidal Extension

Abstract

gETE invading only the strap muscles did not significantly affect DSS, while that invading the posterior organs significantly affected DSS, even when only the RLN was invaded. The data support the applicability of downgrading patients with T3b (≤4 cm) disease to the T2 stage for a better predictability of survival.
