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...

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 ...

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...

Background: Some regrowing nodules after radiofrequency ablation (RFA) of symptomatic large benign thyroid nodules are revealed as malignancies in surgery. The aim of the study was to assess the ultrasound (US) characteristic of thyroid nodules diagnosed as cancer later, the predictive factors for cancer after RFA, and the prevention methods for these cancers to avoid RFA.Materials and Methods: The medical records of 22 thyroid nodules with 18 patients w...
