Elevated CRP and leukocytosis at diagnosis, but not elevated ESR, are prognostic markers in anaplastic thyroid cancer

Objectives: Anaplastic thyroid carcinoma (ATC) is one of the malignancies with the highest mortality among all cancers. Immune cells are highly abundant in ATC tumors and increased infiltration with tumor-associated macrophages is associated with decreased survival. We hypothesize that systemic inflammatory markers are also associated with survival in patients with ATC and are more elevated in ATC compared to poorly differentiated thyroid carcinoma (PDTC).<p class="abstext...

Optimal cut-off values of protrusion angle of tumor on sonography (PATOS) system to predicting extrathyroidal extension in papillary thyroid carcinoma according to location

Bae Dongsik

Background: Extrathyroidal extension (ETE) is an important factor to determine treatment strategy of thyroid cancer. The purpose of this study was to present a new method to predict ETE in papillary thyroid carcinoma (PTC).Methods: This study included 1,481 patients with PTCs. The ETE was classified into minimal and gross ETE. Using an protrusion angle of the tumor on sonography (PATOS) system, we calculated optimal cut-off values to predict ETE accordin...

Comparison in ultrasonography (US) features and the korean-thyroid imaging reporting and DATA system (K-TIRADS) of isthmic and lobar papillary thyroid carcinomas (PTC)

Lee Yoojin

Objective: This study aimed to compare US features and K-TIRADS categories for diagnosing isthmic and lobar PTCs.Methods: From January 2009 to December 2012, 163 patients who underwent thyroid surgery and were confirmed with a postoperative histopathological diagnosis of isthmic PTC were retrospectively included. Fifty-nine patients were excluded because their tumor size was < 0.5 cm, lack of preoperative thyroid US images, poor US image quality, and...

Role of ultrasound in predicting tert promoter mutation in follicular thyroid carcinoma

Kyoung Kim Myoung , Hee Shin Jung , Yeon Hahn Soo , Kim Haejung

Purpose: Telomerase reverse transcriptase (TERT) promoter mutations are associated with tumor aggressiveness. The purpose of our study was to demonstrate the ultrasonographic (US) features of TERT promoter-mutated follicular thyroid cancer (FTC) and to evaluate their predictive performances.Materials and methods: Total 63 patients who had surgically confirmed FTC between August 1995 and April 2021 were included in this study. All of them were available f...

Ultrasonographic prediction of tumor invasiveness in follicular thyroid carcinoma: based on the who classification and tert promoter mutation

Kyoung Kim Myoung , Hee Shin Jung , Yeon Hahn Soo , Kim Haejung

Background: The purpose of this study was to assess the role of ultrasound (US) in predicting tumor invasiveness in follicular thyroid carcinoma (FTC) based on the World Health Organization (WHO) classification and telomerase reverse transcriptase (TERT) promoter mutation.Materials and Methods: This retrospective study included 54 surgically confirmed FTC patients who underwent preoperative US and TERT mutation analysis. The WHO classification consisted ...

Validation of ct-based risk stratification systems for lymph node metastasis in patients with thyroid cancer

Hwa Roh Yun , Rom Chung Sae , Hwan Baek Jung , Jun Choi Young , Sung Tae-Yon , Eun Song Dong , Yong Kim Tae , Hyun Lee Jeong

Objective: To evaluate computed tomography (CT) features for diagnosing metastatic cervical lymph nodes (LNs) in patients with differentiated thyroid cancer (DTC) and propose CT-based risk stratification system modified from the Korean Thyroid Imaging Reporting and Data System (K-TIRADS) guidelines.Materials and Methods: A total of 463 LNs from 397 patients with DTC who underwent preoperative CT staging and US-guided fine needle aspiration of LNs were in...

Macrofollicular variant of papillary thyroid carcinoma: ultrasonographic findings and clinical implications

Oh Jiyun , Hee Shin Jung , Yeon Hahn Soo , Kim Haejung , Lyun Oh Young

Objectives: The macrofollicular variant of papillary thyroid cancer (MFV-PTC) is a rare subtype often lending to a challenging diagnosis. This study evaluated the ultrasonographic (US) features and clinical implication of MFV-PTC.Methods: Records of 14 patients histologically diagnosed with MFV-PTC at our institution over a period of 16 years were retrospectively reviewed. Preoperative US features, Bethesda categories determined by fine-needle aspiration...

Clinical significance of tumor size in gross extrathyroidal extension to strap muscles(T3B) in papillary thyroid carcinoma

Park Joonseon , Kim Kwangsoon , Seong Bae Ja , Kim Jeongsoo

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...
