Management of Recurrent Well-Differentiated Thyroid Carcinoma in the Neck: A Comprehensive Review.

Surgery has been historically the preferred primary treatment for patients with well-differentiated thyroid carcinoma and for selected locoregional recurrences. Adjuvant therapy with radioactive iodine is typically recommended for patients with an intermediate to high risk of recurrence. Despite these treatments, locally advanced disease and locoregional relapses are not infrequent. These patients have a prolonged overall survival that may result in long periods of active disease and the possibility of requiring subsequent treatments. Recently, many new options have emerged as salvage therapies. This review offers a comprehensive discussion and considerations regarding surgery, active surveillance, radioactive iodine therapy, ultrasonography-guided percutaneous ablation, external beam radiotherapy, and systemic therapy for well-differentiated thyroid cancer based on relevant publications and current reference guidelines. We feel that the surgical member of the thyroid cancer management team is empowered by being aware and facile with all management options.

Strategies to Increase Racial and Ethnic Diversity in the Surgical Workforce: A State of the Art Review.

OBJECTIVE: To evaluate strategies to increase racial and ethnic diversity in the surgical workforce among trainees and faculty across surgical specialties. DATA SOURCES: Embase, OVID/Medline, and Web of Science Core Collection. REVIEW METHODS: A review of US-based, peer-reviewed articles examining the effect of targeted strategies on racial and ethnic diversity in the surgical workforce was conducted from 2000 to 2020 with the PRISMA checklist and STROBE tool. Studies without an outlined strategy and associated outcomes were excluded. Eleven studies met inclusion criteria and were completed in general surgery, orthopaedic surgery, and otolaryngology-head and neck surgery. CONCLUSIONS: Efforts to increase exposure to surgery through internship programs and required clerkships with efforts to improve mentorship were common (6 of 11 [54.5%] and 3 of 11 [27.3%] studies, respectively). Three (27.3%) studies aimed to diversify the recruitment and selection process for the residency match and faculty hiring, and 2 (18.2%) aimed to increase representation among trainees, faculty, and leadership through holistic review processes paired with departmental commitment. Outcome metrics included surgical residency applications for individuals underrepresented in medicine, interview and match rates, faculty hiring, measures of a successful academic surgical career, and leadership representation. All strategies were successful in increasing diversity in the surgical workforce. IMPLICATIONS FOR PRACTICE: A convincing yet limited body of literature exists to describe strategies and outcomes that address racial and ethnic diversity in the surgical workforce. While future inquiry is needed to move this field of interest forward, the evidence presented provides a framework for surgical residency programs/departments to develop approaches to increase racial and ethnic diversity.

Facial nerve electrodiagnostics for patients with facial palsy: a clinical practice guideline.

PURPOSE: Facial nerve electrodiagnostics is a well-established and important tool for decision making in patients with facial nerve diseases. Nevertheless, many otorhinolaryngologist-head and neck surgeons do not routinely use facial nerve electrodiagnostics. This may be due to a current lack of agreement on methodology, interpretation, validity, and clinical application. Electrophysiological analyses of the facial nerve and the mimic muscles can assist in diagnosis, assess the lesion severity, and aid in decision making. With acute facial palsy, it is a valuable tool for predicting recovery. METHODS: This paper presents a guideline prepared by members of the International Head and Neck Scientific Group and of the Multidisciplinary Salivary Gland Society for use in cases of peripheral facial nerve disorders based on a systematic literature search. RESULTS: Required equipment, practical implementation, and interpretation of the results of facial nerve electrodiagnostics are presented. CONCLUSION: The aim of this guideline is to inform all involved parties (i.e. otorhinolaryngologist-head and neck surgeons and other medical specialists, therapeutic professionals and the affected persons) and to provide practical recommendations for the diagnostic use of facial nerve electrodiagnostics.

African Head and Neck Society Clinical Practice guidelines for thyroid nodules and cancer in developing countries and limited resource settings.

BACKGROUND: International thyroid nodule and cancer management guidelines generally fail to take into account potential limitations in diagnostic and treatment resources. METHODS: Thyroid cancer specialists from the African Head and Neck Society and American Head & Neck Society Endocrine Section developed guidelines for diagnosis and management of thyroid nodules and cancer in low resource settings. Recommendations were based on literature review and expert opinion, with level of evidence defined. RESULTS: Using the ADAPTE process, diagnostic and treatment algorithms were adapted from the National Comprehensive Cancer Network (NCCN). Low resource settings were simulated by systematically removing elements such as availability of laboratory testing, hormone replacement, imaging, and cytopathology from NCCN guidelines. CONCLUSIONS: Successful management of thyroid nodules and cancer in low resource settings requires adaptation of treatment methodologies. These guidelines define specific scenarios where either more or less aggressive intervention for thyroid pathology may be advisable based on limited available resources.

External-beam radiotherapy for differentiated thyroid cancer locoregional control: A statement of the American Head and Neck Society.

The use of external-beam radiotherapy (EBRT) in differentiated thyroid cancer (DTC) is debated because of a lack of prospective clinical data, but recent retrospective studies have reported benefits in selected patients. The Endocrine Surgery Committee of the American Head and Neck Society provides 4 recommendations regarding EBRT for locoregional control in DTC, based on review of literature and expert opinion of the authors. (1) EBRT is recommended for patients with gross residual or unresectable locoregional disease, except for patients <45 years old with limited gross disease that is radioactive iodine (RAI)-avid. (2) EBRT should not be routinely used as adjuvant therapy after complete resection of gross disease. (3) After complete resection, EBRT may be considered in select patients >45 years old with high likelihood of microscopic residual disease and low likelihood of responding to RAI. (4) Cervical lymph node involvement alone should not be an indication for adjuvant EBRT.

Pediatric thyroidectomy in a high volume thyroid surgery center: Risk factors for postoperative hypocalcemia.

INTRODUCTION: Hypocalcemia is a common complication following thyroid surgery. We seek to report on our experience in pediatric thyroidectomy in a high volume thyroid surgery center and accurately assess the incidence of postoperative hypocalcemia. MATERIALS AND METHODS: A retrospective review of patients aged 18 and younger who underwent thyroid surgery between 1992 and 2013. The primary endpoints were the occurrence of postoperative hypocalcemia as by defined as a nadir calcium <8.0mg/dL and being discharged on oral calcium supplementation, need for intravenous calcium and the occurrence of permanent hypoparathyroidism. RESULTS: 171 patients who underwent 186 thyroid operations were analyzed. The average age was 15.4years with 82.3% female. The most common indications for surgery were nodular disease (74.7%) and hyperthyroidism (12.4%). 24 patients (12.9%) experienced postoperative hypocalcemia with 13 (7.0%) requiring intravenous calcium infusion. One patient (0.9%) experienced permanent hypoparathyroidism. Risk factors for postoperative hypocalcemia included total thyroidectomy (OR 7.39, p<0.01), central and bilateral lateral neck dissection (OR 22.26, p=0.01), Graves' disease (OR 3.99, p=0.02), and malignancy (OR 2.96, p=0.03). CONCLUSIONS: Pediatric patients who undergo total thyroidectomy for underlying malignancy or Graves' disease and those who have more extensive nodal dissections are at increased risk of developing this postoperative hypocalcemia. These patients may benefit from more vigilant preoperative preparation and postoperative calcium and vitamin D supplementation.

Management of recurrent and persistent metastatic lymph nodes in well-differentiated thyroid cancer: a multifactorial decision-making guide for the Thyroid Cancer Care Collaborative.

BACKGROUND: Well-differentiated thyroid cancer (WDTC) recurs in up to 30% of patients. Guidelines from the American Thyroid Association (ATA) and the National Comprehensive Cancer Network (NCCN) provide valuable parameters for the management of recurrent disease, but fail to guide the clinician as to the multitude of factors that should be taken into account. The Thyroid Cancer Care Collaborative (TCCC) is a web-based repository of a patient's clinical information. Ten clinical decision-making modules (CDMMs) process this information and display individualized treatment recommendations. METHODS: We conducted a review of the literature and analysis of the management of patients with recurrent/persistent WDTC. RESULTS: Surgery remains the most common treatment in recurrent/persistent WDTC and can be performed with limited morbidity in experienced hands. However, careful observation may be the recommended course in select patients. Reoperation yields biochemical remission rates between 21% and 66%. There is a reported 1.2% incidence of permanent unexpected nerve paralysis and a 3.5% incidence of permanent hypoparathyroidism. External beam radiotherapy and percutaneous ethanol ablation have been reported as therapeutic alternatives. Radioactive iodine as a primary therapy has been reported previously for metastatic lymph nodes, but is currently advocated by the ATA as an adjuvant to surgery. CONCLUSION: The management of recurrent lymph nodes is a multifactorial decision and is best determined by a multidisciplinary team. The CDMMs allow for easy adoption of contemporary knowledge, making this information accessible to both patient and clinician.

Evidence-based medicine in otolaryngology, part 1: the multiple faces of evidence-based medicine.

Evidence-based medicine, with its capacity to improve patient outcomes, has grown prominent throughout the medical field. Otolaryngology is at a crucial stage in the expansion of evidence-based medicine, with its impact seen in many arenas. As the evidence continues to shape our field, we hope to serve our otolaryngology community through this invited series, which is dedicated to the exposition of evidence-based medicine and its applications. This first installment examines evidence-based medicine itself and its multiple interpretations, including a purist view, a population-based view, and a view centered on the individual. Strengths and weaknesses of each are discussed, as well the potential for unification and evolution of these concepts. We also place evidence-based medicine in the context of the mindset of traditional medicine and anticipate future developments.

Invasive thyroid cancer: management of the trachea and esophagus.

Well-differentiated thyroid cancer most commonly presents as an intrathyroidal tumor; however, extrathyroidal extension occurs in approximately 6% to 13% of patients and carries a significant negative impact on survival. Extrathyroidal disease may involve critical structures in the central neck, including the recurrent laryngeal nerves, trachea, esophagus, and larynx, requiring surgery extending significantly beyond the thyroid gland. Appropriate surgical management is of great importance and can normalize survival curves, whereas gross residual disease postoperatively may lead to recurrence and decreased survival. Adjuvant postoperative therapies for thyroid cancers with extrathyroidal extension include thyroid hormone suppression, radioactive iodine therapy, and external beam radiotherapy. This summary reviews approaches to the management of invasive thyroid cancers involving the aerodigestive tract.
