Background: The tall cell variant (TCV) of papillary thyroid carcinoma (PTC) (TCVPTC) is the most common aggressive variant of PTC. Classic PTC with tall cell features (TCF) is defined as PTC with noticeable tall cells but the percentage of these cells is lower than that required for the diagnosis of TCVPTC. We aimed to investigate the potential differences between TCVPTC and classic PTC with TCF with respect to clinicopathological characteristics and long-term oncologic outco...

Purpose: Few studies have examined the clinical utility of ultrasonography-guided pectoralis nerve block II (PECS II) during wide flap dissection of SP robot-assisted transaxillary thyroidectomy (SP-RATT). This study presents preliminary results of a randomized controlled trial.Methods: A total of 48 adult patients (aged ≥ 20 years) who underwent elective SP-RATT (including lobectomy) or total thyroidectomy from November 2022 to February 2023 at Se...

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...
