Introduction: Thyroid isthmus has lack of normal parenchyma, and it connects both of thyroid lobes with lymphatic drainage. It is known that isthmic papillary thyroid cancer (PTC) presents frequent extrathyroidal extensions (ETE), multifocality and lymph node involvement. Therefore, many surgeons prefer total thyroidectomy and central compartment neck dissection (CCND) for the radical treatment of PTC located in thyroid isthmus. The purpose of this study is to figure out the c...

Background: It has been studied that larger tumor size in T3b has a worse prognosis than T3b with smaller tumor size. The present study aims to compare the clinicopathological characteristics among modified T categories and clarify the significance of tumor size in T3b on the DSS of differentiated thyroid carcinoma(DTC).Methods: A total of 6282 patients with DTC who underwent thyroid surgery at a single center were retrospectively analyzed. Patients with...

Background: The presence of extathyroidal extension (ETE) is associated with locoregional recurrence and distant metastases in papillary thyroid carcinoma (PTC). ETE is classified into gross ETE (gETE) and minimal ETE (mETE). The mETE was recently excluded from the T3 category in the TNM staging system. The purpose of this study is to compare the recurrence risk of mETE and gETE in PTC patients through propensity score matching analysis. And a comparison in the same way for pa...
