Purposes: There is an increasing trend towards performing more radical resections instead of a subtotal resection for benign thyroid disease. The aim of this study was to examine the effect of this change in practice on the surgical treatment of bilateral thyroid diseases in this unit.
Methods: The data on 367 patients that underwent a bilateral thyroidectomy were categorized by dividing the operation types into 4 groups: (1) total thyroidectomy (TT), (2) near-total thyroidectomy, (3) Dunhill procedure, and (4) bilateral subtotal thyroidectomy.
Results: A statistically significant change in the choice of thyroidectomy occured during the study period (p < 0.001). TT has replaced subtotal thyroidectomy (STT; bilateral subtotal thyroidectomy and Dunhill procedure) as the preferred routine surgical procedure for bilateral benign thyroid diseases in this clinic. The permanent complication rates were similar for all surgical procedures. The rate of secondary thyroidectomy for both recurrence of multinodular goiter and incidental thyroid carcinoma were significantly higher in the STT groups, than the total in the TT and near-total thyroidectomy patients.
Conclusions: Total or near total thyroidectomy procedures are now being increasingly employed to treat bilateral benign thyroid disease, and are as safe as the sub-total thyroidectomy procedures, which are more conservative and associated with significantly higher recurrence rates.

In the era of molecular testing, thyroid nodules with indeterminate cytology are increasingly being managed nonoperatively. The false-negative rates of these molecular tests, and therefore missed malignancies, are not well defined in real-world clinical practice. This retrospective study of patients undergoing fine needle aspiration (FNA) biopsy at our health system between November 2017 and March 2022 included nodules with The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) III and IV cytology and negative, currently negative, or negative but limited ThyroSeq version 3 (TSv3) results.

Although patients with anaplastic thyroid cancer (ATC) generally have a poor prognosis and there are currently no effective treatment options, survival and response to therapy vary between patients. Genomic and transcriptomic profiles of ATC have been reported; however, a comprehensive study of the tumor microenvironment (TME) of ATC is still lacking. This study aimed to elucidate the TME characteristics associated with ATC and their prognostic implications.

Background/objectives: Accurate diagnosis is essential to avoid unnecessary procedures for thyroid incidentalomas (TIs). Advances in radiomics and machine learning applied to medical imaging offer promise for assessing thyroid nodules. This study utilized radiomics analysis on F-18 FDG PET/CT to improve preoperative differential diagnosis of TIs.

Background: The differential diagnosis between benign and malignant thyroid nodules continues to be a major challenge in clinical practice. The rising incidence of thyroid neoplasm and the low incidence of aggressive thyroid carcinoma, urges the exploration of strategies to improve the diagnostic accuracy in a pre-surgical phase, particularly for indeterminate nodules, and to prevent unnecessary surgeries. Only in 2022, the 5th WHO Classification of Endocrine and Neuroendocrine Tumors, and in 2023, the 3rd Bethesda System for Reporting Thyroid Cytopathology and the European Thyroid Association included biomarkers in their guidelines.

Background: Traditional teaching dictated that patients with recurrent thyroid cysts undergo excision owing to a 12% risk malignancy. Ultrasound evaluation now determines management of these patients augmented by fine needle biopsy. In UK, a non-diagnostic category for thyroid cysts (Thy1c) exists, whereas the Bethesda system combines 'non-diagnostic-cyst fluid only' into Category I along with paucicellular and acellular results.
