Abstract
OBJECTIVE The incidence of thyroid cancer has significantly increased in recent decades. Although most thyroid cancers are small and carry an excellent prognosis, a subset of patients present with advanced thyroid cancer, which is associated with increased rates of morbidity and mortality. The management of thyroid cancer requires a thoughtful individualized approach to optimize oncologic outcomes and minimize morbidity associated with treatment. Because endocrinologists usually play a key role in the initial diagnosis and evaluation of thyroid cancers, a thorough understanding of the critical components of the preoperative evaluation facilitates the development of a timely and comprehensive management plan. The following review outlines considerations in the preoperative evaluation of patients with thyroid cancer. METHODS A clinical review based on current literature was generated by a multidisciplinary author panel. RESULTS A review of considerations in the preoperative evaluation of thyroid cancer is provided. The topic areas include initial clinical evaluation, imaging modalities, cytologic evaluation, and the evolving role of mutational testing. Special considerations in the management of advanced thyroid cancer are discussed. CONCLUSION Thorough and thoughtful preoperative evaluation is critical for formulating an appropriate treatment strategy in the management of thyroid cancer.

Optimization of Thyroid Volume Determination by Stitched 3D-Ultrasound Data Sets in Patients with Structural Thyroid Disease. Biomedicines 2023; 11:biomedicines11020381. [PMID: 36830918 PMCID: PMC9952922 DOI: 10.3390/biomedicines11020381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 01/23/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023] Open
Abstract
Ultrasound (US) is the most important imaging method for the assessment of structural disorders of the thyroid. A precise volume determination is relevant for therapy planning and outcome monitoring. However, the accuracy of 2D-US is limited, especially in cases of organ enlargements and deformations. Software-based "stitching" of separately acquired 3D-US data revealed precise volume determination in thyroid phantoms. The purpose of this study is to investigate the feasibility and accuracy of 3D-US stitching in patients with structural thyroid disease. A total of 31 patients from the clinical routine were involved, receiving conventional 2D-US (conUS), sensor-navigated 3D-US (3DsnUS), mechanically-swept 3D-US (3DmsUS), and I-124-PET/CT as reference standard. Regarding 3DsnUS and 3DmsUS, separately acquired 3D-US images (per thyroid lobe) were merged to one comprehensive data set. Subsequently, anatomical correctness of the stitching process was analysed via secondary image fusion with the I-124-PET images. Volumetric determinations were conducted by the ellipsoid model (EM) on conUS and CT, and manually drawn segmental contouring (MC) on 3DsnUS, 3DmsUS, CT, and I-124-PET/CT. Mean volume of the thyroid glands was 44.1 ± 25.8 mL (I-124-PET-MC = reference). Highly significant correlations (all p < 0.0001) were observed for conUS-EM (r = 0.892), 3DsnUS-MC (r = 0.988), 3DmsUS-MC (r = 0.978), CT-EM (0.956), and CT-MC (0.986), respectively. The mean volume differences (standard deviations, limits of agreement) in comparison with the reference were -10.50 mL (±11.56 mL, -33.62 to 12.24), -3.74 mL (±3.74 mL, -11.39 to 3.78), and 0.62 mL (±4.79 mL, -8.78 to 10.01) for conUS-EM, 3DsnUS-MC, and 3DmsUS-MC, respectively. Stitched 3D-US data sets of the thyroid enable accurate volumetric determination even in enlarged and deformed organs. The main limitation of high time expenditure may be overcome by artificial intelligence approaches.

Surgical Case Volume has an Impact on Outcomes for Patients with Lateral Neck Disease in Thyroid Cancer. Ann Surg Oncol 2021; 29:1141-1150. [PMID: 34705145 DOI: 10.1245/s10434-021-10923-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 09/27/2021] [Indexed: 11/18/2022]
Abstract
BACKGROUND This study aimed to assess whether surgical case volume for lateral neck dissection has an impact on the survival of patients who have well-differentiated thyroid cancer (WDTC) with lateral cervical node metastases. The authors used a population-based cohort study design. METHODS The study cohort consisted of WDTC patients in Ontario Canada who underwent thyroidectomy and lateral neck dissection. These patients were identified using both hospital- and surgeon-level administrative data between 1993 and 2017 (n = 1832). Surgeon and hospital volumes were calculated based on the number of cases managed in the year before the procedure by the physician and at the institution managing each case, respectively, and divided into tertiles. Multilevel Cox regression models were used to estimate the effect of volume on disease-free survival (DFS). RESULTS A crude model without patient or treatment characteristics demonstrated that DFS was associated with both higher surgeon volume tertiles (p < 0.01) and higher hospital volume tertiles (p < 0.01). After control for clustering, patient/treatment covariates, and hospital volume, the lowest surgeon volume tertile (range, 0-20/year; mean, 6.5/year) remained an independent statistically significant negative predictor of DFS (hazard ratio, 1.71; 95 % confidence interval, 1.22-2.4; p < 0.01). CONCLUSION Surgeon lateral neck dissection case volume is a predictor of better DFS for thyroid cancer patients, with the lowest surgeon volume tertile (<20 neck dissections per year) demonstrating poorer DFS.

Abstract
BACKGROUND The study aim was to systematically review literature evaluating surgeon volume-outcome relationships for thyroid and parathyroid operations in order to inform surgical quality improvement initiatives. Current literature suggests surgeons who perform a high volume of thyroid and/or parathyroid operations have better outcomes than low volume surgeons, though specific volume definition are not standardized. METHODS Eligible studies were selected through a literature search focused on the effect of surgeon volume on thyroid and parathyroid surgery patient outcomes. The literature search was conducted in accordance with the PRISMA guidelines. Publication dates extended from January 1998 to February 2021, and were limited to articles published in English. RESULTS A total of 33 studies were included: 25 studies evaluating thyroid surgery outcomes, 4 studies evaluating parathyroid surgery outcomes, and 4 studies evaluating both thyroid and parathyroid (mixed) surgery outcomes. Higher volume thyroid and parathyroid surgeons were found to be associated with fewer surgical and medical complications, shorter length of hospital stay, and reduced total cost when compared to lower volume surgeons. This volume-outcome relationship was also found to specifically affect the complication and recurrence rates for thyroid cancer patients undergoing surgery, especially for individuals with advanced stage disease. CONCLUSION The heterogeneity in cut-offs used for characterizing surgeons as high versus low volume, and also in subsequent patient outcome measures, limited direct study comparisons. The trend of improved patient outcomes with higher surgeon volume for both thyroid and parathyroid surgeries was consistently present in all studies reviewed.

Abstract
Conventional ultrasound (US) is time-consuming, and results are subjected to high interobserver variability. In this study, the reliability of a novel thyroid US cine loop standard operating procedure (SOP) applied by non-physicians (Medical Technical Assistant, MTA) is investigated. Thirty-three consecutive patients (22 females, 11 males) were enrolled. Patients underwent conventional thyroid US performed by a nuclear medicine physician and additional MTA US cine loop according to a local SOP that includes transversal and sagittal cine loops covering the entire thyroid. The video sequences were transferred to the Picture Archiving and Communication System (PACS) for second reading purposes. MTA US data were not considered for medical reports but for blinded second reading review of the PACS images. The results of conventional physician US reports and reviewed MTA US cine loops were compared regarding size determinations of the thyroid and its nodules, as well as Thyroid Imaging Reporting and Data Systems (TIRADS) classification of all identified lesions. The results revealed very high concordance between conventional physician US and MTA US cine loop review for both size measurements and TIRADS classifications (r(s) = 0.84-0.99, p < 0.0001 each). Minor technical impairments were identified. The evaluated thyroid US cine loop SOP enables reliable second reading results and can be applied by non-physicians.

Abstract
Simple Summary Total thyroidectomy used to be recommended for all thyroid cancers. We now know that some thyroid cancers have a relatively low risk of recurrence. Today, for some of these cancers, depending on the type of tumor, its’ size and other tumor characteristics, a thyroid lobectomy (or hemithyroidectomy) can be performed without increasing the patient’s risk of cancer recurrence. Thyroid lobectomy has the advantages of having less risk of surgical complications and a less frequent need for thyroid hormone replacement therapy. This approach is not optimal for all thyroid cancers, however, and careful tumor and patient selection are necessary. This review explains the rationale and criteria for patient selection for thyroid lobectomy for selected thyroid cancers. Abstract Many recent publications and guidelines have promoted a “more is less” approach in terms of treatment for low to intermediate risk differentiated thyroid cancer (DTC), which comprise the vast majority of thyroid cancers: less extensive surgery, less radioactive iodine, less or no thyroid hormone suppression, and less frequent or stringent follow-up. Following this approach, thyroid lobectomy has been proposed as a means of decreasing short- and long-term postoperative morbidity while maintaining an excellent prognosis for tumors meeting specific macroscopic and microscopic criteria. This article will examine the pros and cons of thyroid lobectomy for low to intermediate risk cancers and discuss, in detail, criteria for patient selection and oncological outcomes.

Abstract
OBJECTIVE Endocrine surgery is an expanding field within otolaryngology. We hypothesized that a novel endocrine surgery fellowship model for in-practice otolaryngologists could result in expert-level training. STUDY DESIGN Qualitative clinical study with chart review. SETTING Urban community practice and academic medical center. METHODS Two board-certified general otolaryngologists collaborated with a senior endocrine surgeon to increase their endocrine surgery expertise between March 2015 and December 2017. The senior surgeon provided intensive surgical training to both surgeons for all of their endocrine surgeries. Both parties collaborated with endocrinology to coordinate medical care and receive referrals. All patients undergoing endocrine surgery during this time frame were reviewed retrospectively. RESULTS A total of 235 endocrine surgeries were performed. Of these, 198 thyroid surgeries were performed, including 98 total thyroidectomies (48%), 90 lobectomies (45%), and 10 completion thyroidectomies (5%). Sixty cases demonstrated papillary thyroid carcinoma, 11 follicular thyroid carcinoma, and 4 medullary thyroid carcinoma. Neck dissections were performed in 14 of the cases. Thirty-seven parathyroid explorations were performed. There were no reports of permanent hypoparathyroidism. Thirteen patients (5.5%) developed temporary hypoparathyroidism. Six patients (2.5%) developed postoperative seroma. Three patients (1.3%) developed postoperative hematomas requiring reoperation. One patient (0.4%) developed permanent vocal fold paralysis, and 3 patients (1.3%) had temporary dysphonia. Thirty-five of 37 (94.5%) parathyroid explorations resulted in biochemical resolution of the patient's primary hyperparathyroidism. CONCLUSION This is the first description of a new fellowship paradigm where a senior surgeon provides fellowship training to attending surgeons already in practice.

Abstract
BACKGROUND N6-Methyladenosine (m6A) is a ubiquitous RNA modification with vital roles in various cancers, but little is known about its role in papillary thyroid carcinoma (PTC), a common endocrine malignancy. METHODS In this study, an m6A RNA methylation regulator-based biomarker signature was developed for the effective prediction of prognosis in patients with PTC. The gene expression profiles of m6A RNA methylation regulators and the corresponding clinical information was downloaded from The Cancer Genome Atlas (TCGA). Differentially expressed m6A RNA methylation regulators between tumor and normal control samples, and correlation expression levels, clinical parameters, and outcomes were evaluated. And a prognostic signature was built using a PTC cohort from TCGA. RESULTS The expression level of HNRNPC was remarkably upregulated in tumor samples, while WTAP, RBM15, YTHDC2, YTHDC1, FTO, METTL14, METTL3, ALKBH5, KIAA1429, YTHDF1, and ZC3H13 were significantly downregulated in the cancer specimens compared with those in control samples. A three-gene prognostic signature comprising RBM15, KIAA1429, and FTO could predict overall survival in patients with PTC. In addition, the prognostic signature-based risk score was identified as an independent prognostic indicator for PTC. CONCLUSIONS We established a robust m6A RNA methylation regulator-based molecular signature for predicting prognosis in patients with PTC with high accuracy; this signature might provide important guidance for therapeutic strategies.
