RESUMO
OBJECTIVE: To investigate a possible link between breast and thyroid cancer. METHODS: A multicenter retrospective review of patients in the electronic medical records of six Accrual to Clinical Trial (ACT) institutions with both breast cancer and thyroid carcinoma. Each center queried its data using a predefined data dictionary. Information on thyroid and breast cancer included dates of diagnosis, histology, and patient demographics. RESULTS: A random-effects model was used. There were 4.24 million women's records screened, 44 605 with breast cancer and 11 846 with thyroid cancer. The relative risks observed at each institution ranged from 0.49 to 13.47. The combined risk ratio (RR) estimate was 1.77 (95% confidence interval: 0.50-5.18). CONCLUSION: There was no association between the risk of developing thyroid cancer and being a breast cancer survivor compared to no history of breast cancer, but the range of relative risks among the participating institutions was wide. Our findings warrant further study of more institutions with larger sample size. Additionally, further analysis of the significance of regional RR differences may be enlightening.

OBJECTIVES: To provide a clinical disease state review of recent relevant literature and to generate expert consensus statements regarding the breadth of pediatric thyroid cancer diagnosis and care, with an emphasis on thyroid surgery. To generate expert statements to educate pediatric practitioners on the state-of-the-art practices and the value of surgical experience in the management of this unusual and challenging disease in children. METHODS: A literature search was conducted and statements were constructed and subjected to a modified Delphi process to measure the consensus of the expert author panel. The wording of statements, voting tabulation, and statistical analysis were overseen by a Delphi expert (J.J.S.). RESULTS: Twenty-five consensus statements were created and subjected to a modified Delphi analysis to measure the strength of consensus of the expert author panel. All statements reached a level of consensus, and the majority of statements reached the highest level of consensus. CONCLUSION: Pediatric thyroid cancer has many unique nuances, such as bulky cervical adenopathy on presentation, an increased incidence of diffuse sclerosing variant, and a longer potential lifespan to endure potential complications from treatment. Complications can be a burden to parents and patients alike. We suggest that optimal outcomes and decreased morbidity will come from the use of advanced imaging, diagnostic testing, and neural monitoring of patients treated at high-volume centers by high-volume surgeons.

OBJECTIVE: We aimed to evaluate the use of 4-dimensional computed tomography (4DCT) for characterization of thyroid nodules. METHODS: Our study drew from 100 consecutive patients with primary hyperparathyroidism who underwent 4D parathyroid CT imaging for adenoma localization. Included subjects had tissue sampling of a thyroid nodule within 3 months of 4DCT. RESULTS: Twenty subjects (18 women and 2 men) had thyroid nodules that were pathologically confirmed. Precontrast nodule attenuation was significantly lower in malignant nodules when compared with benign nodules (36 vs 61 HU, P = 0.05). Arterial phase and delayed phase nodule attenuations were not significantly different in malignant and benign nodules (128 vs 144 HU, P = 0.7; 74 vs 98 HU, P = 0.3). CONCLUSIONS: Our initial experience with a small group of patients was unable to support the use of 4DCT for characterizing thyroid nodules; however, precontrast nodule attenuation was significantly lower in malignant nodules when compared with benign nodules.

Background Robotic surgery has been recently used as a novel tool for remote access thyroid surgery. We performed a meta-analysis of the current literature to examine the safety and oncological efficacy of robotic surgery compared to endoscopic and conventional approaches for different thyroid procedures. Methods A systematic search of the online data bases was done using the following (MeSH) terms "robotic surgery," "robotic thyroidectomy," "robot-assisted thyroidectomy," and "robot-assisted thyroid surgery." Outcomes measured included total operative time, length of hospital stay, postoperative thyroglobulin levels, and postoperative complications. Statistical differences were analyzed between groups through the standard means and/or relative risk by using STATA analytical software. Results In this study, 144 articles were identified; of which 18 of them met our inclusion criteria, totaling 4878 patients. Robotic approach was associated with longer total operative time (mean difference of 43.5 minutes) when compared to the conventional cervical approach (95% CI = 20.9-66.2; P < .001). Robotic approach was also found to have a similar risk of total postoperative complications when compared to the conventional and endoscopic approaches. Conclusion Robotic thyroid surgery is as safe, feasible and provides similar periperative complications and oncological outcomes when compared to both, conventional cervical and endoscopic approaches. However, robotic thyroid surgery is associated with longer operative time when compared to the conventional open approach.

PURPOSE: To investigate whether termination of bisphosphonates (BPs) affects resolution of bone exposure and symptomatic disease in patients with established medication-related osteonecrosis of the jaw (MRONJ). PATIENTS AND METHODS: The studied population included 84 patients with established MRONJ who discontinued BP therapy before treatment (n = 21), at treatment initiation (n = 38), or later (or never) in the treatment course (n = 25). These 3 groups were compared using Kaplan-Meier curves and log-rank tests for differences in the respective times to resolution of 1) bone exposure for any treatment modality, 2) bone exposure not requiring radical surgery, and 3) disease symptoms. RESULTS: Patients who continued BPs after the start of treatment exhibited significantly delayed resolution of symptoms (median 12 months; 95% confidence interval 8 to 15) compared with those who discontinued BPs before (3 months; 2 to 5) and at (6 months; 3 to 7) presentation (P < .005). CONCLUSIONS: Independent of treatment modality and MRONJ stage at presentation, discontinuing BP before or at treatment initiation is associated with faster resolution of MRONJ symptoms compared with continuing the drug throughout jaw treatment. Patients should be counseled that continuing their BP medication after an established MRONJ diagnosis (compared to stopping the BP at diagnosis) may delay resolution of maxillofacial symptoms by approximately 6 months.

The primary aim of this study was to investigate the immediate effects of partial versus complete head rotation and chin tuck on pharyngeal swallowing pressures and durations in the pharynx and UES of normal, healthy adults. Ten individuals (3 men and 7 women; age range 54-76 years) served as participants. Solid-state intraluminal manometry was performed with the participants in the upright position while performing swallows with the head in the normal position, head rotated (partial and complete), chin tucked, and chin down. A cervical range of motion (CROM) inclinometer was used to accurately measure the degree of head rotation and chin tuck. The CROM inclinometer has not been used before so this is the first study to our knowledge to quantify degree of head rotation and chin tuck. Manometric data derived from these healthy participants indicate both partial and complete head rotations can increase the duration of UES relaxation and decrease UES residual pressure. Chin tuck may be effective in increasing durations in the upper pharynx. Partial chin tuck (chin down) decreases UES residual pressure. Complete head rotation and chin tuck provide more overall benefit than partial maneuvers. However, for patients with limited head and neck mobility, partial posture changes impact the pharynx in similar ways and may provide clinically meaningful benefits. Additional research on patient populations is warranted.

OBJECTIVE: Vitamin D deficiency affects parathyroid hormone levels and is endemic in the American population due to diet and lifestyle. The aim of this study was to evaluate a treatment algorithm using weekly doses of 50,000 IU of Vitamin D2 for thyroid and parathyroid surgery patients. STUDY DESIGN: Prospective, non-randomized. SETTING: University health sciences center. SUBJECTS AND METHODS: Patients at a thyroid center being treated for benign and malignant thyroid diseases or parathyroid disease. Subjects with total vitamin D levels less than 30 ng/dl were prospectively treated with weekly doses of 50,000 IU of vitamin D2 (D2) for durations dependent upon initial vitamin D (25-hydroxyvitamin D) levels. Vitamin D levels were measured after the treatment intervals and change in levels from baseline was determined. RESULTS: Subjects receiving 8 weeks of therapy demonstrated an average increase in vitamin D level of 13.4 ng/ml, 10 weeks of therapy showed an increase of 16.35 ng/ml, and 12 weeks showed an average increase of 21.6 ng/ml. The treatment groups had success rates of 82%, 75%, and 71% after 8, 10, and 12 weeks of therapy respectively. When only compliant patients were evaluated (defined as greater than 3-ng/ml increase after therapy), the success rates after 8, 10, and 12 weeks increased to 95%, 79%, and 71% respectively. CONCLUSIONS: A simple algorithm using 50,000 IU of vitamin D2 corrects its deficiency in the majority of subjects treated. This is a simple method of treatment for thyroid and parathyroid patients who are vitamin D deficient. Thyroid and parathyroid conditions are frequently treated by otolaryngologists and vitamin D deficiency can complicate their diagnosis and/or management.

BACKGROUND: This study examined the trajectory of health-related quality of life (HRQoL) for patients with clinical stage N0 HNSCC enrolled in ACRIN 6685 who underwent elective neck dissection(s). METHODS: HRQoL of 230 patients in the ACRIN 6685 trial was measured prospectively up to 2 years following surgery using the University of Washington Quality of Life instrument. RESULTS: General Health Within the Last 7 Days did not differ significantly from baseline at any follow-up. General Health Relative to Before Cancer fell significantly by 5.8 points following surgery (p = 0.048), and then returned to 3.0 points above baseline at 1 year (p = 0.65). For Overall Quality of Life, HRQoL fell significantly by 4.3 points following surgery (p = 0.031) and then returned to levels not significantly different from baseline. CONCLUSIONS: Patients with stage N0 HNSCC experience significant declines in HRQoL immediately following surgery, including neck dissection, which recovers to near or better than baseline within 1-2 years.

Importance: Oncocytic (Hürthle cell) thyroid carcinoma is a follicular cell-derived neoplasm that accounts for approximately 5% of all thyroid cancers. Until recently, it was categorized as a follicular thyroid carcinoma, and its management was standardized with that of other differentiated thyroid carcinomas. In 2022, given an improved understanding of the unique molecular profile and clinical behavior of oncocytic thyroid carcinoma, the World Health Organization reclassified oncocytic thyroid carcinoma as distinct from follicular thyroid carcinoma. The International Thyroid Oncology Group and the American Head and Neck Society then collaborated to review the existing evidence on oncocytic thyroid carcinoma, from diagnosis through clinical management and follow-up surveillance. Observations: Given that oncocytic thyroid carcinoma was previously classified as a subtype of follicular thyroid carcinoma, it was clinically studied in that context. However, due to its low prevalence and previous classification schema, there are few studies that have specifically evaluated oncocytic thyroid carcinoma. Recent data indicate that oncocytic thyroid carcinoma is a distinct class of malignant thyroid tumor with a group of distinct genetic alterations and clinicopathologic features. Oncocytic thyroid carcinoma displays higher rates of somatic gene variants and genomic chromosomal loss of heterozygosity than do other thyroid cancers, and it harbors unique mitochondrial DNA variations. Clinically, oncocytic thyroid carcinoma is more likely to have locoregional (lymph node) metastases than is follicular thyroid carcinoma-with which it was formerly classified-and it develops distant metastases more frequently than papillary thyroid carcinoma. In addition, oncocytic thyroid carcinoma rarely absorbs radioiodine. Conclusions and Relevance: The findings of this review suggest that the distinct clinical presentation of oncocytic thyroid carcinoma, including its metastatic behavior and its reduced avidity to radioiodine therapy, warrants a tailored disease management approach. The reclassification of oncocytic thyroid carcinoma by the World Health Organization is an important milestone toward developing a specific and comprehensive clinical management for oncocytic thyroid carcinoma that considers its distinct characteristics.

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) can become resistant to some chemotherapy and becomes a clinical challenge when it recurs. There are few agents identified for second-line treatment of resistant head and neck cancer. Therefore, we evaluated the role of fusaric acid (FA) as a possible agent for treatment for chemotherapy-resistant laryngeal squamous cell carcinoma. METHODS: The HEp2 and docetaxel-resistant HEp2 (HEp-Doc) cell lines were created from human laryngeal cancer. Cell lines were exposed to FA at increasing concentrations (0.1, 0.3, and 0.5 mM) and time intervals of 24, 48, 72, and 96 h. The effects on cell survival, apoptosis, and cytokine and protein expression were analyzed. RESULTS: FA treatment in the HEp-Doc cells showed greater reduction of cell number and colony-forming units and more apoptosis when compared to HEp2 and required less time to reduce cell number. Four cytokines were detected in HEp2 cancer cells that increased with FA treatment. Pro-caspase-9 and -7 and poly (ADP-ribose) polymerase also increased with FA treatment. CONCLUSION: FA may be an agent to be considered in cases of HNSCC treatment resistance or post-docetaxel recurrence. Further investigation of FA in vitro and in vivo is indicated.

INTRODUCTION: FDG PET/CT was prospectively studied in 287 cN0 head and neck cancer patients in ACRIN 6685, and additional analysis of neck FDG uptake upon recurrence-free survival (RFS) and overall survival (OS) was performed. PATIENTS AND METHODS: Two hundred eight had analyzable data. Survival analysis was performed to compare RFS and OS based on neck FDG visual assessment (VA) and SUV max . For SUV max , the optimal thresholds were calculated using conditional inference trees on a randomly selected 70% training data set and validated using the remaining 30% of data. Kaplan-Meier curves with log-rank tests were generated for the patient groups based on VA and optimal SUV max thresholds, and the hazards ratios (HRs) and 95% confidence intervals (CIs) were also calculated. Hypothesis testing was set at a significance level of 0.05. RESULTS: A total of 73.9% of bilateral cN0 and 50.0% of unilateral cN0 were alive at the end of the study with the remaining being dead or lost to follow-up. Overall survival median follow-up time was 24.0 months (interquartile range, 15.8-25.3; range, 0-37.0). A total of 63.3% of bilateral cN0 and 42.5% of unilateral cN0 patients remained disease free during the study. Recurrence-free survival median follow-up time was 23.9 months (interquartile range, 12.4-25.2; range, 0-35.6). Visual assessment of necks by our panel of radiologists was significantly associated with RFS (HR [95% CI], 2.30 [1.10-4.79]; P = 0.02), but not with OS (HR [95% CI], 1.64 [0.86-3.14]; P = 0.13). The optimal SUV max thresholds were 2.5 for RFS and 5.0 for OS. For SUV max assessment, applying the optimal thresholds to the 30% test data yielded HRs (95% CIs) of 2.09 (0.61-7.14; P = 0.23) for RFS and 3.42 (1.03-11.41; P = 0.03) for OS. The SUV max threshold of 5.0 was significantly associated with RFS (HR [95% CI], 5.92 [1.79-19.57]; P < 0.001). CONCLUSIONS: Neck FDG uptake by VA is significant for RFS. An SUV max threshold of 5.0 is significantly associated with OS and RFS.

BACKGROUND: With recent efforts to decrease opioid use following surgery, this study aims to answer: what pain regimen do patients follow at home? Is it controlling pain? METHODS: This is a prospective, pilot study of thyroid and parathyroid surgery patients. Patients were prescribed acetaminophen, ibuprofen, and tramadol dispensed in smart pill (Pillsy) bottles that record "events" corresponding to medication use. Patients received messages querying their current pain level. Patients were compared to historical controls. RESULTS: 26 patients were in the Pillsy group and 30 in the control group. In the Pillsy group, pain scores averaged 3.67 out of 10 in the first 24 h after surgery and decreased each day. Patients took an average of 6.45 doses of acetaminophen, 6.64 doses of ibuprofen, and 1.82 doses of tramadol in the first week. CONCLUSIONS: Pain scores are highest in the first 24 h after surgery and decrease thereafter. This acceptable level of pain can be achieved with non-opioid medications.

Importance: Counseling prior to thyroid cancer (TC) treatment is an essential component of informed consent. An informed patient affects treatment-related expectations and patient engagement, factors that contribute significantly to patient-reported quality-of-life outcomes. Objective: To describe experiences with pretreatment counseling among survivors of TC and to test factors associated with self-reported treatment meeting expectations. Design, Setting, and Participants: A cross-sectional survey was administered between October 18, 2019, and February 8, 2020, to members of ThyCa: Thyroid Cancer Survivors' Association Inc, and to individuals accessing the public-facing ThyCa website. Survey respondents were asked 55 questions, including 4 free-text questions and 2 multiple-choice questions about pretreatment counseling. Main Outcomes and Measures: Respondents self-reported (1) their unmet information needs, (2) rates of treatment meeting expectations, and (3) rates of treatment understanding. A mixed-methods analysis was performed, including qualitative content analysis of free-text responses and multivariable logistic regression of factors associated with self-reported levels of treatment meeting expectations. Results: Of the 1412 survey respondents, 1249 were women (88.4%). The median age at diagnosis was 48 years (range, 18-85 years), and the median age at the time of survey completion was 60 years (range, 18-87 years). A total of 1259 respondents (89.2%) provided free-text responses to the question, "What would you tell someone newly diagnosed with your same condition?" Of these individuals, 526 (37.2%) reported inadequate pretreatment plan understanding and 578 (40.9%) reported that their treatment experience did not meet their expectations. Treatment met expectations for only 95 respondents (18.1%) reporting an inadequate pretreatment plan understanding. Of the 526 survivors of TC reporting a lack of understanding, 473 (90.0%) provided additional textual comments, most commonly in the categories of postoperative treatment, surveillance, and treatment effects. On multivariable logistic regression, self-reported failure to have an understanding of TC treatment was independently associated with failure of treatment to meet expectations (odds ratio, 5.1 [95% CI, 3.7-6.9]). Patients reporting a full understanding of their treatment plan were 5-fold more likely to indicate that their initial treatment experience was on par with expectations, independent of reported postoperative complications, age, sex, and other potential confounders. Conclusions and Relevance: In this survey study, a substantial proportion of survivors of TC reported inadequate pretreatment understanding. This gap in understanding was associated with high levels of self-reported failure of treatment to meet expectations, which in turn is associated in other studies with poorer patient-reported quality-of-life outcomes. These outcomes may be improved by addressing gaps in patient understanding so expectations more closely match TC diagnosis and treatment pathways.

Importance: Identification and preservation of parathyroid glands (PGs) remain challenging despite advances in surgical techniques. Considerable morbidity and even mortality result from hypoparathyroidism caused by devascularization or inadvertent removal of PGs. Emerging imaging technologies hold promise to improve identification and preservation of PGs during thyroid surgery. Observation: This narrative review (1) comprehensively reviews PG identification and vascular assessment using near-infrared autofluorescence (NIRAF)-both label free and in combination with indocyanine green-based on a comprehensive literature review and (2) offers a manual for possible implementation these emerging technologies in thyroid surgery. Conclusions and Relevance: Emerging technologies hold promise to improve PG identification and preservation during thyroidectomy. Future research should address variables affecting the degree of fluorescence in NIRAF, standardization of signal quantification, definitions and standardization of parameters of indocyanine green injection that correlate with postoperative PG function, the financial effect of these emerging technologies on near-term and longer-term costs, the adoption learning curve and effect on surgical training, and long-term outcomes of key quality metrics in adequately powered randomized clinical trials evaluating PG preservation.

Spasmodic torticollis or cervical dystonia (CD) is the most common form of focal dystonia and is characterized by sustained abnormal muscle contractions in the head and neck area resulting in abnormal positioning or posturing of the head. The dystonic muscle spasms associated with spasmodic torticollis may affect any combination of neck muscles. Three cases are reported of spasmodic torticollis that were treated by a dental appliance with individual varying occlusal heights to open the maxillomandibular vertical dimension. Upon increasing the vertical dimension of occlusion, there was a slowing and/or discontinuance of the symptoms of cervical dystonia. The proposed hypothesis for this reversal is that there may be neuritis of the auriculotemporal branch of the trigeminal nerve, which has direct input into the reticular formation (RF), and it may activate the cells of the pontine region of the RF known for the control and deviation of head posture. There is growing clinical evidence that temporomandibular joint (TMJ) dysfunction may be a factor in this neurological and painful disorder when it coexists.

BACKGROUND: To prove the concept of diagnosing primary hyperparathyroidism (pHPT) without calcium and parathyroid hormone (PTH) values and identifying potential risk factors for pHPT. METHODS: Data were extracted from the clinical data warehouse (CDW) at the University of Arkansas for Medical Sciences (UAMS) Epic EHR (2014-2019). RESULTS: 1737 patients with over 185 000 rows of clinical data were provided in a relational structure and processed/flattened to facilitate modeling. Phenotype elements were identified for pHPT without advance knowledge of calcium and PTH levels. The area under the curve (AUC) for the prediction of pHPT using our model was 0.86 with sensitivity and specificity of 0.8953 and 0.6686, respectively, using a 0.45 probability threshold. CONCLUSION: Primary hyperparathyroidism was predicted from a dataset excluding calcium and PTH data with 86% accuracy. This approach needs to be validated/refined on larger samples of data and plans are in place to do this with other regional/national datasets.

To our knowledge, no prior multicenter clinical trial has reported interobserver agreement of 18F-FDG PET/CT scans for staging of clinical N0 neck in head and neck cancer. Methods: A total of 287 participants were recruited. For visual analysis, positive nodal uptake of 18F-FDG was defined as uptake visually greater than activity seen in the blood pool. Results: The negative predictive value of the 18F-FDG PET/CT for N0 clinical neck was 86% or above for visual assessment (95% CI, 86%-88%) for the 2 central readers and above 90% (95% CI, 90%-95%) for SUVmax for central reads and site reads dichotomized at the optimal cutoff value of 1.8 and the prespecified cutoff value of 3.5, respectively. The κ coefficients between the 2 expert readers and between central reads and site reads varied between 0.53 and 0.78. Conclusion: The NPV of the 18F-FDG PET/CT for N0 clinical neck was 86% or above for visual assessment and above 90% for SUVmax cut points of 1.8 and 3.5 with moderate to substantial agreements.

BACKGROUND: Intraoperative neuromonitoring (IONM) techniques have evolved over the past decade into intermittent IONM (I-IONM) and continuous IONM (C-IONM) modes of application. Despite many prior publications on both types of IONM, there remains uncertainty about what outcomes should be measured for each form of IONM. The primary objective of this paper is to define categories of benefit for I-IONM/C-IONM and to clarify and standardize their reporting outcomes. METHODS: Expert review consensus statement utilizing modified Delphi methodology. RESULTS: I-IONM provides diagnosis, classification, and prevention of nerve injury through accurate and early nerve identification. C-IONM provides real-time information on nerve functional integrity and thus may prevent some types of nerve injury but cannot assist in nerve localization. Sudden mechanisms of nerve injury cannot be predicted or prevented by either technique. CONCLUSIONS: I-IONM and C-IONM are complementary techniques. Future studies evaluating the utility of IONM should focus on outcomes that are appropriate to the type of IONM being utilized.

OBJECTIVE: Traditionally, data regarding thyroidectomy were extracted from billing databases, but information may be missed. In this study, a multi-institutional pediatric thyroidectomy database was used to evaluate recurrent laryngeal nerve (RLN) injury and hypoparathyroidism. STUDY DESIGN: Retrospective multi-institutional cohort study. SETTING: Tertiary care pediatric hospital systems throughout North America. METHODS: Data were individually collected for thyroidectomies, then entered into a centralized database and analyzed using univariate and multivariable regression models. RESULTS: In total, 1025 thyroidectomies from 10 institutions were included. Average age was 13.9 years, and 77.8% were female. Average hospital stay was 1.9 nights and 13.5% of patients spent at least 1 night in the pediatric intensive care unit. The most frequent pathology was papillary thyroid carcinoma (42%), followed by Graves' disease (20.1%) and follicular adenoma (18.2%). Overall, 1.1% of patients experienced RLN injury (0.8% permanent), and 7.2% experienced hypoparathyroidism (3.3% permanent). Lower institutional volume (odds ratio [OR], 3.57; 95% CI, 1.72-7.14) and concurrent hypoparathyroidism (OR, 3.51; 95% CI, 1.64-7.53) correlated with RLN injury on multivariable analysis. Graves' disease (OR, 2.27; 95% CI, 1.35-3.80), Hashimoto's thyroiditis (OR, 4.67; 95% CI, 2.39-9.09), central neck dissection (OR, 3.60; 95% CI, 2.36-5.49), and total vs partial thyroidectomy (OR, 7.14; 95% CI, 4.55-11.11) correlated with hypoparathyroidism. CONCLUSION: These data present thyroidectomy information and complications pertinent to surgeons, along with preoperative risk factor assessment. Multivariable analysis showed institutional volume and hypoparathyroidism associated with RLN injury, while hypoparathyroidism associated with surgical indication, central neck dissection, and extent of surgery. Low complication rates support the safety of thyroidectomy in pediatric tertiary care centers.
