Abstract
Thyroid carcinoma is the most common malignancy of the endocrine system and accounts for nearly 1.5% of all new cancer cases in India. The incidence of thyroid cancers is on the rise secondary to multiple factors including the widespread use of radiological imaging. Surgery remains the cornerstone of treatment, and radioactive iodine therapy plays a pivotal role in differentiated thyroid cancer. Radiation therapy appears to be an underutilized treatment modality. In this review, we have summarized the role of radiation in the treatment of thyroid cancer.

[PMID: 33358294 DOI: 10.1016/j.jvoice.2020.11.027] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 11/25/2020] [Accepted: 11/27/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVE Our study aimed to both identify the incidence and clinical presentation of patients presenting with idiopathic vocal fold paralysis (IVFP). Secondarily we aimed to assess the radiographic findings of computed tomography (CT) studies along the course of the vagus and recurrent laryngeal nerves (RLN), specifically measuring for potential areas of compression at the skull base and mediastinum. We hypothesized that a proportion of patients diagnosed with IVFP would have significant differences in measurements when compared to age-gender matched controls on CT imaging. STUDY DESIGN Institutional review board approved retrospective cohort study METHODS: We assessed patients presenting to a tertiary voice care center between 2003 and 2019 with diagnosis of vocal fold paralysis. Data collected includes demographics, clinical exam findings, and CT measurements including dimensions at bilateral jugular foramen, aortopulmonary (AP) window and surrounding vascular structures. Statistical analysis was then performed using Pearson χ2, and Mann Whitney U tests to determine differences variables of interest. RESULTS A total of 606 patients were reviewed. Of these patients 60 (9.9%) patients were determined to have IVFP. Left-sided VFP was seen more commonly in 78.3% (N = 47) of idiopathic patients. Our IVFP group had an overall higher incidence of cardiovascular disease [OR = 3.378, 95%CI 1.907-5.941, P < 0.001] compared to those with identified causes for paralysis. Specifically, IVFP patients showed a higher incidence of combined cardiovascular co-morbidities (P < 0.001), mitral valve stenosis (P = 0.007), pulmonary hypertension (P < 0.0001) and congestive heart failure (P < 0.001). When evaluating CT imaging, the AP window was mentioned in only 2 (3.3%) of our idiopathic patients CT reports. The IVFP cohort had a lower median AP window volume (P = 0.020) when compared to age-gender matched controls. This significantly smaller AP window volume was also seen when only left sided IVFP compared to both right-sided paralysis (P < 0.001) and age matched control patients (P < 0.001). CONCLUSION The significance of cardiovascular comorbidities combined with findings of statistically narrowed AP window may help provide an explanation of a subset of patients diagnosed with IVFP.

Indian J Otolaryngol Head Neck Surg 2022; 74:1920-1928. [PMID: 36452820 PMCID: PMC9702032 DOI: 10.1007/s12070-020-01914-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Accepted: 06/13/2020] [Indexed: 11/28/2022] Open
Abstract
To analyse the pattern of laryngotracheal invasion (LTI) by papillary-thyroid-carcinoma (PTC) and outcomes of their management. We undertook a retrospective chart review to study patterns of LTI by PTC and to evaluate outcomes of surgical modalities used to treat PTC with LTI. Out of 246cases of PTC, 26-cases had LTI (male-12, female-14, mean-age-55.6 years, range 42-73 years). Common clinical presentation were neck swelling, respiratory distress/stridor and vocal cord paralysis in 100%, 8 (30.8%) and 10 (38.5%) cases respectively. PTC was staged according to AJCC-TNM staging system (T4a-24, T4b-02, N1a-12, N1b-14, M0-25, and M1-01). CT-scan showed obvious LTI and tracheal narrowing in 11(42.3%) and 18(69.2%) cases respectively. All cases underwent total thyroidectomy with central-compartment-clearance. Unilateral and bilateral lateral-neck-dissection was performed in 08 and 06cases respectively. Pattern of Intra-operative LTI were as follows: trachea-13cases, trachea and cricoid-05cases, thyroid cartilage-6cases, trachea, cricoid and thyroid cartilage-2 cases and intra-luminal involvement in 4cases. Modified Shin's staging was used to stage LTI. LTI were superficial, deep-extra-luminal and intra-luminal in 13, 09 and 04cases respectively. LTI was managed by shave-excision, window-resection of trachea, sleeve-resection of trachea and anastomosis, partial laryngectomy and total-laryngectomy in 13,02,04,05 and 2 cases respectively. All patients received radio-active-iodine (RAI) and TSH-suppression-therapy post-operatively. Mean follow-up period was two-years (range 18-30 months). One-case had radio-iodine non-avid local recurrence with lung metastases one-year post-operatively. Shave-excision is adequate for tumours not infiltrating into outer perichondrium. Tracheal-resection and total/partial laryngectomy may be required in cases with laryngo-tracheal cartilage or intra-luminal involvement. Adequate surgical excision along with postoperative RAI and TSH-suppression-therapy gives good loco-regional disease control in PTC with LTI.

Abstract
Purpose Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. LncRNA HOTAIR (HOx Transcript AntIsense RNA) and Galectin-3 are involved in PTC. This study explored the clinical effect of lncRNA HOTAIR/Galectin-3 on PTC patients. Methods Subjects were assigned into PTC (160 cases) and benign thyroid tumor groups (150 cases). Fasting peripheral venous blood was collected. LncRNA HOTAIR/Galectin-3 expressions in serum were detected. Subjects were assigned into HOTAIR/Glactin-3 high/low expression groups and their correlation with age, gender, BMI, tumor size, pathological stage, TSH, TPO-Ab, and TG-Ab in PTC was analyzed. Receiver operating characteristic (ROC) curve was conducted on diagnostic efficacy of HOTAIR or/and Galectin-3. The difference of area under the curve (AUC) was compared and analyzed. Results HOTAIR and Glactin-3 were higher in PTC group and correlated with tumor pathological stage. Higher HOTAIR/Glactin-3 expression indicated a more advanced TNM stage. LncRNA HOTAIR was positively correlated with TPO-Ab and TG-Ab. AUC of HOTAIR for PTC diagnosis was 0.895, with 96.00% specificity and 80.63% sensitivity. AUC of Glactin-3 for PTC diagnosis was 0.817, with 66.67% specificity and 78.75% sensitivity. AUC of HOTAIR combining with Glactin-3 for PTC diagnosis was 0.969 with 96.00% specificity and 87.50% sensitivity. AUC of lncRNA HOTAIR was higher than that of Glactin-3, while AUC of the combination was higher than that of lncRNA HOTAIR or Glactin-3. Conclusion LncRNA HOTAIR and Glactin-3 were highly expressed in PTC. The combination detection of lncRNA HOTAIR/Glactin-3 had higher diagnostic efficiency on the differential diagnosis of benign thyroid tumor and PTC.

Abstract
Management of thyroid cancer requires a multidisciplinary approach including head and neck/endocrine surgeons, endocrinologists, oncologists, and radiologists. The radiographic evaluation of thyroid cancer is critical for complete and precise staging and affects the surgical approach to address these cancers. The purpose of this article is to briefly review the common thyroid cancer pathologies and surgical considerations in thyroid cancer, focusing on the extent of surgery and the influence of preoperative imaging on surgical decision-making. This article assumes that a diagnosis of thyroid cancer has been made and does not discuss the workup or surveillance of thyroid nodules.

Abstract
Introduction Tracheal invasion in thyroid cancer occurs in one-third of locally advanced cases and is the third most common site of infiltration following strap muscles and recurrent laryngeal nerves. Surgical resection plays an important role in the management strategy followed by either radioactive iodine or external beam radiotherapy. Nonetheless, there has been still controversy about the optimal extension of the surgery. Case Presentation. Total thyroidectomy, airway resection and bilateral neck dissection were performed in two cases diagnosed as advanced thyroid cancer with tracheal invasion (stage IV according to McCaffrey). The first case underwent partial tracheal resection and direct anastomosis by the V-shape technique, while the latter one required tracheal resection and permanent tracheotomy. After one-year follow-up, no evidence of tumor recurrence or any postoperative complications were found. Conclusion Surgical resection still remains the mainstay of management for advanced thyroid cancer in general and for tracheal invasion cases in particular. The decision of surgical resection and tracheal reconstruction methods mostly depends on the extent of tracheal invasion.

Abstract
BACKGROUND AND OBJECTIVES Total laryngectomy in thyroid cancer is controversial. Functional and oncologic outcomes are needed to inform surgical indications in this population. METHODS A retrospective cohort study was performed at a tertiary referral center from 1997 to 2018 to identify patients with a diagnosis of thyroid carcinoma who underwent total laryngectomy. Complications, survival outcomes, and functional outcomes were analyzed. RESULTS Thirty patients met the inclusion criteria. The mean age was 62 years (range, 30-88 years) and the male-to-female ratio was 1:2.75. The most common diagnosis was well-differentiated thyroid cancer (53.3%), followed by poorly differentiated (30%) and anaplastic (16.7%). Total laryngectomy was performed with a 10% rate of Clavien-Dindo Grade III-V complications. The median overall survival was 40 months (range, 1-237). Five-year overall survival was 39.5% and disease-specific survival was 51.1%. Locoregional control was achieved in 80.0% of patients. Twelve months postoperatively, 100% of surviving patients were taking oral intake and 86.4% had a self-reported functional voice. CONCLUSION Total laryngectomy for locally advanced thyroid cancer is safe and provides acceptable rates of locoregional control. While the risk of distant metastases remains high, advances in systemic therapy may justify aggressive local control strategies to improve the quality of life.

Abstract
Invasion is a key feature of malignancy and an important element in the classification, risk-stratification, and staging of thyroid cancers. However, the histopathologic criteria for tumor capsular invasion, angioinvasion, and extrathyroidal extension (ETE) have varied among pathologists, both in practice as well as in studies assessing the clinical significance of these findings. In this review, we provide historic context for the controversies surrounding the definition of invasion in thyroid neoplasms and highlight recent efforts to standardize how pathologists report capsular invasion, angioinvasion, and ETE. We offer practical suggestions for distinguishing invasion from its mimics and provide an algorithmic approach for classifying thyroid tumors based on integration of tumor invasiveness, nuclear atypia, and architectural pattern.

Abstract
Around 1/3 of patients of locally advanced carcinoma thyroid present with tracheal infiltration either alone or along with infiltration of other adjacent structures. Even though trachea is infiltrated, adequate resection is the main modality of treatment in these patients. We retrospectively analysed carcinoma thyroid patients who were operated at our institute, between January 2011 and December 2018, and underwent thyroidectomy with tracheal or laryngeal resection. Seventeen patients underwent tracheal/laryngeal resection with thyroidectomy. The mean age of patients was 57 years. Six and eleven were male and female, respectively, 0.14 (82%) patients had dyspnoea on presentation, 6 had hoarseness of voice, 6 had haemoptysis, and in 2 patients, neck swelling was the only complain. Two patients in our study presented with acute stridor, underwent emergency intubation and subsequently surgery. Two other patients had bulky pedunculated tumour in preoperative bronchoscopy and required tracheostomy for intubation before proceeding with surgery. In 11 patients, sleeve resection followed by end-to-end anastomosis was done, window resection was done in 3 patients, partial laryngectomy in 1, and total laryngectomy in 2 patients. In 10 patients (59%), the site of infiltration was in the lateral tracheal wall, with relatively small posterior primary (mean size 3.7 cm) in the thyroid lobe. Two patients developed postoperative complication, one patient with sleeve resection had secondary haemorrhage, and one patient who underwent window resection with myochondrial thyroid lamina flap reconstruction developed salivary fistula. These patients underwent re exploration with tracheostomy and were subsequently decannulated. Preoperative diagnosis of tracheal infiltration helps in better planning of surgery and counseling the patients of any possible complication. Clinical workup and pre-emptive diagnosis is therefore of paramount importance.

Abstract
RATIONALE Compared with most malignant tumors, papillary thyroid carcinoma (PTC) is usually associated with favorable survival and low recurrence rate. The prognostic factors of PTC include age, sex, tumor size, enlarged lymph nodes, and extrathyroidal extension. Among the extrathyroidal extension, upper aerodigestive tract (ADT) invasion by PTC is a marker of more aggressive tumor behavior, defining a subpopulation of patients at a greater risk of recurrence and death. PATIENT CONCERNS A 61-year-old woman had a cervical mass that was slowly growing for three years. Additionally, she had haemoptysis of 1-year duration. During the month prior to her visit, she had difficulty breathing. DIAGNOSIS Neck ultrasonography (US) and thyroid computed tomography (CT) images both showed a well-defined calcified mass on the left lobe of the thyroid gland. Additionally, the thyroid CT revealed that part of the mass protruded into the lumen which resulted in the thickening on the left side of the trachea. Accordingly, her diagnoses were as follows: firstly, a solid mass on the left lobe of the thyroid gland with tracheal compression; and finally, the space-occupying airway lesion. INTERVENTIONS She underwent a bronchoscopic examination, which revealed a mass blocking most of the upper endoluminal trachea. Thus, the mass was resected at the upper tracheal segment, followed by electrotome and argon plasma coagulation treatment. She was then transferred to the Thyroid Surgery Department. Thyroid surgeons took the surgical type of bilateral subtotal thyroidectomy + exploration of bilateral recurrent laryngeal nerve + dissection of the lymph node in neck central area + circumferential sleeve resection + end-to-end anastomosis + tracheotomy in the patient. OUTCOMES After surgery, she recovered well without any local recurrence or distant metastasis. LESSONS When patients with PTC have haemoptysis, hoarseness, dyspnea, or any other symptoms, and the imaging examinations reveal a space-occupying lesion in the thyroid and airway, clinicians should focus on PTC with tracheal invasion, a bronchoscopic examination must be immediately performed because the subsequent surgical management depends on the degree of tracheal invasion.

Abstract
Background Recurrent laryngeal nerve (RLN) invasion in papillary thyroid carcinoma (PTC) is one of the main predictors of poor prognosis. The present study investigated the risk factors for RLN invasion in PTC patients. Methods A total of 3,236 patients who received thyroidectomy due to PTC in Thyroid and Parathyroid Surgery Center of West China Hospital of Sichuan University were reviewed. Demographics and clinical factors, imaging examination (ultrasonography) characteristics, surgical details, postoperative pathological details, recurrence, and postoperative complications were recorded. Univariate and multivariate analyses were used to study the risk factors of RLN invasion, Kaplan–Meier method was performed to compare the outcomes of tumor recurrence. Results Patients with RLN invasion had a higher recurrence rate than those in the control group (p<0.001). Multivariate analyses showed that age greater than 45 years (p<0.001), a largest tumor size bigger than 10 mm (p<0.001), clinical lymph node metastasis (cN1) (p<0.001), posterior focus (p<0.001), extrathyroidal extension (p<0.001), esophageal extension (p<0.001), tracheal extension (p<0.001), and preoperative vocal cord paralysis (p<0.001) were independent predictors for RLN invasion. Conclusion PTC patients with RLN invasion have a negative prognosis and a higher recurrence rate. Meticulous operation and careful follow-up of patients with the above factors is recommended.

Abstract
BACKGROUND Invasive disease is a poor prognostic factor for patients with differentiated thyroid cancer (DTC). Uncontrolled central neck disease is a common cause of distressing death for patients presenting in this manner. Advances in assessment and management of such cases have led to significant improvements in outcome for this patient group. This article reviews the patterns of invasion and a contemporary approach to investigation and treatment of patients with invasive DTC. SUMMARY Aerodigestive tract invasion is reported in around 10% of case series of DTC. Assessment should include not only clinical history and physical examination with endoscopy as indicated, but ultrasound and contrast-enhanced cross-sectional imaging. Further studies including positron emission tomography should be considered, particularly in recurrent cases that are radioactive iodine (RAI) resistant. Both the patient and the extent of disease should be carefully assessed prior to embarking on surgery. The aim of surgery is to resect all gross disease. When minimal visceral invasion is encountered early, "shave" procedures are recommended. In the setting of transmural invasion of the airway or esophagus, however, full thickness excision is required. For intermediate cases in which invasion of the viscera has penetrated the superficial layers but is not evident in the submucosa, opinion is divided. Early reports recommended an aggressive approach. More recently authors have tended to recommend less aggressive resections with postoperative adjuvant therapies. The role of external beam radiotherapy continues to evolve in DTC with support for its use in patients considered to have RAI-resistant tumors. CONCLUSIONS Patients with invasive DTC require a multidisciplinary approach to investigation and treatment. With detailed assessment, appropriate surgery, and adjuvant therapy when indicated, this patient group can expect durable control of central neck disease, despite the aggressive nature of their primary tumors.

Abstract
BACKGROUND Haemoptysis is an uncommon presenting symptom to the ENT clinic and ward, but has potentially sinister aetiology. This article aims to provide a systematic and evidence-based method of managing patients with haemoptysis. METHODS The data in this article are based on a literature search performed using PubMed in August 2013. The keywords used included 'haemoptysis' in combination with 'otolaryngology', 'ENT', 'head & neck', 'diagnosis', 'management', 'investigations' and 'treatment'. RESULTS The majority of published literature on the subject is level IV evidence. However, this can guide ENT specialists in assessing, investigating and managing presentations of haemoptysis. CONCLUSION Understanding the different causes of haemoptysis is important for the otolaryngologist. The main concern is the detection of a malignant lesion in the upper aerodigestive tract or tracheobronchial tree. A thorough history and systematic examination can aid diagnosis.

Abstract
AbstractIntroduction:Thyroid cancers infiltrating the upper aerodigestive tract are not uncommon. The management of these cases can be demanding, with a high level of surgical skill required to achieve adequate primary resection and reconstruction.Materials and methods:This study was a single institution series of seven patients, managed over two years, who underwent tracheal resection for advanced thyroid cancer. All patients were older than 45 years (range, 45–65 years) and were predominantly male (six of seven). All patients presented to us with a swelling in the neck. Fine needle aspiration cytology detected thyroid cancer in all patients. None of the patients required a tracheostomy prior to surgery; however, they all had varying levels of airway compromise. One patient had lung metastasis at presentation. In all patients, the airway was successfully secured with fibre-optic assisted intubation prior to surgery. All patients underwent a total thyroidectomy with tracheal resection and anastomosis. Montgomery's suprahyoid release was utilised to achieve adequate laryngeal drop. None of the patients required a tracheostomy in the post-operative period. All patients received adjuvant therapy with either radioiodine ablation and/or radiotherapy.Conclusion:Tracheal resection and primary reconstruction is a feasible surgical procedure for patients with thyroid cancer infiltrating the upper aerodigestive tract, with good clinical outcomes. However, the morbidity of the procedure mandates careful case selection, airway management and meticulous surgical technique.

Abstract
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.

Abstract
Thyroid carcinoma invasion of the aerodigestive tract and recurrent laryngeal nerve (RLN) are important factors with increase in morbidity and mortality. Primary treatment is surgery; the decision about the extent of surgery is difficult, because preserving function is as essential as removal of the tumor. This article discusses the literature relating to the assessment of disease, surgical management, and adjuvant therapy for invasive thyroid cancer of the aerodigestive tract and RLN and makes suggestions based on the authors' experience.

Abstract
AIM The aim of this study is to evaluate the outcome of different modes of resection in papillary thyroid carcinoma (PTC) with laryngotracheal invasion. MATERIALS AND METHODS Sixty-four primary PTCs with laryngotracheal invasion between 1964 and 2003 were retrospectively analyzed (17 men and 47 women; mean age, 61.6 years; mean follow-up, 92.3 months). Thirteen curative resections included six pharyngolaryngoesophagectomies, two total laryngectomies, and five circumferential resections (complete surgery). Eighteen patients who were candidates for curative resection refused to undergo complete surgery to avoid functional impairment, especially laryngeal function (incomplete surgery). Thirty-three patients with minimal invasion underwent shave or partial resection (conservative surgery). Clinical outcomes were compared between the three groups. The influence of different types of surgery and invasion was also evaluated by Cox proportional hazard analysis. RESULTS Three (23.1%) complete, 17 (94.4%) incomplete, and 4 (13.8%) conservative surgery patients died of disease (P < 0.0001). The 10-year disease-specific survival (Kaplan-Meier) in complete, incomplete, and conservative surgery patients were 62.9, 11.1, and 87.7%, respectively (log rank test, P < 0.0001). Incomplete surgery related to worse prognosis [p < 0.0001; hazard ratio (HR), 12.9) than complete or conservative surgery. Tracheal deep invasion (p = 0.0019, HR 7.6) and larynx invasion (p < 0.0001, HR 9.9) related to worse prognosis than minimal invasion. CONCLUSION Curative resection improves clinical outcomes in PTCs with laryngotracheal invasion. Conservative resection for minimal invasion also can achieve favorable prognosis. The degree of tumor invasion is significantly related to survival.

Abstract
PURPOSE To determine the role of adjuvant external-beam radiotherapy (EBRT) in the management of patients with well-differentiated thyroid cancer invading the trachea. METHODS AND MATERIALS Of 1,098 thyroid cancer patients, 68 (6%) were found to have tracheal invasion, and they all received "shave" excision of the tracheal cartilage. Among them, 12 patients had no postoperative residuum, 43 patients had microscopic residuum, and 13 patients had macroscopic residuum. All patients were divided into two groups according to treatment modality with or without EBRT; (1) the control group (n = 43) and (2) the EBRT group (n = 25). RESULTS The locoregional recurrence rate for EBRT patients was much lower than that of control patients (51% for the control group vs. 8% for the EBRT group) (p < 0.01). The 10-year local progression-free survival rate for the EBRT group was significantly better than that of the control group (89% in the EBRT group vs. 38% in the control group) (log-rank, p < 0.01). The use of adjuvant EBRT after conservative surgery was an independent prognostic factor in univariate and multivariate analyses. CONCLUSIONS External-beam radiotherapy was found to be effective, particularly in patients with thyroid cancer invading the trachea with microscopic or gross residuum after conservative surgery.

Abstract
BACKGROUND Vocal cord paralysis is associated with extrathyroidal invasive malignancy. This study was performed to analyze the presentation of patients with invasive thyroid malignancy and to determine the preoperative symptomatic and radiographic correlates of vocal cord paralysis. METHODS In a group of 365 consecutive patients undergoing thyroidectomy, the group of 21 patients with invasive thyroid malignancy was compared with the 344 patients who had benign thyroid disease or noninvasive cancers. RESULTS Preoperative recurrent laryngeal nerve paralysis was a robust marker for invasive thyroid malignancy, being present in 70% of patients with invasive disease and only 0.3% of patients with noninvasive disease. Vocal cord paralysis was associated with voice change in only one third of patients. Preoperative computed tomography was read as positive for vocal cord paralysis in only 25% of patients. CONCLUSIONS Laryngoscopic examination is essential for the detection of vocal cord paralysis preoperatively. Symptomatic voice assessment and radiographic evaluation are insufficient. Preoperative vocal cord paralysis tracts with invasive disease and facilitates preoperative recognition of disease extent, allowing for appropriate operative planning and central neck clearance at first operation. Because of the prevalence (approximately 6% in our study) of invasive thyroid disease, the importance of preoperative diagnosis of invasive disease in operative planning and patient counseling, and the importance of vocal cord functional analysis in recurrent laryngeal nerve management algorithms for nerves found infiltrated at operation, and laryngoscopic examination is recommended for all patients undergoing thyroid operation.

Abstract
BACKGROUND Invasion of the larynx by differentiated thyroid gland carcinoma is uncommon but causes serious morbidity and mortality when present. METHODS The clinicopathologic characteristics of 5 patients in which a total laryngectomy had to be performed for differentiated thyroid carcinoma are analyzed. Special reference is paid to the histologic intralaryngeal tumor spread, which is evaluated on whole-organ section. RESULTS All patients presented with hoarseness and/or dyspnea. Two patients are alive at 44 and 115 months. One patient died of intercurrent disease 2 months and 2 patients with disease 6 and 14 months after surgery. In all cases, intralaryngeal tumor spread was observed. Invasion of the larynx occurs by direct extension or by posterior tumor growth around the edge of the thyroid cartilage. CONCLUSION In rare cases, differentiated thyroid carcinoma can widely infiltrate the larynx, making total laryngectomy unavoidable. The diagnosis of intralaryngeal tumor spread is done by imaging and endoscopy.

Abstract
The management of locally advanced thyroid carcinoma can be challenging. Differing philosophies exist for the treatment of invasive disease affecting the upper aerodigestive tract. The ability to maximize local control and overall survival while minimizing the morbidity of a radical resection is the goal of care in these patients. This article will review the literature concerning the presentation, preoperative evaluation, and the subsite treatment of locally aggressive well-differentiated thyroid carcinoma.

Abstract
Although most patients with differentiated thyroid cancer (DTC) of follicular cell origin enjoy a relatively good prognosis, some patients unfortunately present with or develop locally advanced DTC which leads to significant local morbidity and mortality. DTC accounts for 54-94% of all locally advanced thyroid cancers. DTC invasion of the recurrent laryngeal nerve, strap muscles and trachea are the most common followed by invasion of the esophagus, internal jugular vein and carotid artery. Surgical resection is the primary treatment for locally advanced DTC. Although the optimal surgical approach (ranging from conservative shave excision to aggressive en bloc resection of tumor and vital structures) in patients with locally advanced DTC is controversial, a curative resection should be the goal unless complete tumor resection results in unwanted perioperative morbidity and mortality or widely metastatic disease is present. Postoperative radioiodine ablation with TSH suppression is imperative after surgical resection of locally advanced DTC. Patients with microscopic or small gross residual disease, after surgical resection, may benefit from postoperative external radiotherapy for local control of disease.

Abstract
Pre-operative evaluation of esophageal infiltration is sometimes difficult in patients with advanced thyroid cancer even with recent imaging modalities. We evaluated the accuracy of endoscopic ultrasonography (EUS) in diagnosing esophageal infiltration of thyroid cancer. Twenty-nine patients with advanced thyroid cancer underwent EUS and other imaging examinations before surgery. The diagnostic accuracy of EUS was compared with that of magnetic resonance imaging (MRI) and esophagography based on pathologic findings in 27 of the 29 cases. EUS clearly demonstrated the 5-layer structure of the esophageal wall. EUS detected cancer invasion into the muscularis propria of the esophagus correctly in 8 of 10 patients diagnosed pathologically with muscular infiltration. EUS was significantly more accurate than MRI and esophagography (88.9% vs 63.0% and 66.7%, respectively). The specificity of EUS was also significantly better than the specificities of MRI or esophagography (94.1% vs 58.8% and 64.7%, respectively). The sensitivity, positive predictive value and negative predictive value of EUS tended to be better than those of MRI and esophagography. EUS is useful in evaluating the esophageal infiltration of thyroid cancer. This method has the further advantage of detecting the exact depth of cancer invasion into the esophageal wall.

Abstract
BACKGROUND Controversy exists about the routes of invasion (extrathyroidal versus lymphogenic extension) when differentiated carcinoma (DTC) and medullary thyroid carcinoma (MTC) invade the cervicovisceral axis (ie, larynx, trachea, esophagus). METHODS We carried out an institutional analysis, from November 1994 to October 1999, of 451 consecutive patients undergoing surgery for DTC and MTC. RESULTS Irrespective of tumor entity, carcinomas with cervicovisceral invasion (n = 34) were significantly larger and displayed higher pT categories (mainly pT4) than noninvasive carcinomas. In invasive papillary thyroid carcinoma (PTC) and MTC, the rates of positive lymph nodes were significantly higher than in noninvasive controls. When separate logistic regression analyses were fitted for laryngeal, tracheal, and esophageal invasion, extrathyroidal growth (pT4) consistently was a significant factor predictive of invasion in both DTC and MTC, with relative risks of 10.9 to 67.8. As the routes of invasion are similar in DTC and MTC, all data were pooled for multivariate analyses. Herein, the pN1 category had a significant impact only on esophageal invasion, with a relative risk of 4.7. CONCLUSIONS Invasion of the cervicovisceral axis is more often caused by extrathyroidal growth than by nodal metastasis. To keep nodal metastasis from encroaching onto the cervicovisceral axis, paratracheal and paraesophageal lymph nodes should be cleared from the cervicocentral compartment at the primary operation.

Abstract
Thyroid imaging approach is based on the preliminary clinical evaluation. Lesions that are smaller than 2 cm should be assessed with US, which is capable of discriminating masses as small as 2 mm and distinguishing solid from cystic nodules. US-guided FNAB provides tissue for cytologic examination of thyroid nodules. CT and MR imaging are indicated for larger tumors (greater than 3 cm diameter) that extend outside the gland to adjoining structures, including the mediastinum, and retropharyngeal region. Metastatic lymph nodes in the neck and invasion of the aerodigestive tract are also in the realm of CT and MR imaging. Thyroid nodules are categorized on scintigraphy as hot or cold nodules. Hot nodules are rarely malignant, whereas cold nodules have an incidence of 10% to 20% of malignancy. Calcifications (amorphous, globular, nodular, and linear) occur in adenomas and carcinomas and have no differential diagnostic features except for psammomatous calcifications, which are a pathognomonic finding in papillary carcinomas and a small percentage of medullary carcinomas. Papillary carcinoma is the most common malignant tumor (80%) followed by follicular (20% to 25%); medullary (5%); undifferentiated; anaplastic carcinomas (< 5%); lymphoma (5%); and metastases. Lymph node metastases are common in papillary carcinoma, 50% at presentation, and less common in follicular carcinomas. The metastatic nodes in papillary carcinoma may enhance markedly (hypervascular); show increased signal intensity on T1-weighted images (increased thyroglobulin content or hemorrhage); and reveal punctate calcifications. Localized invasion of the larynx, trachea, and esophagus occurs predominantly in papillary and follicular carcinomas; the incidence is less than 5%. Ectopic thyroid tissue may be encountered in the tongue (foramen cecum); along the midline between posterior tongue and isthmus of thyroid gland; lateral neck; mediastinum; and oral cavity. Goiter and malignant tumors, notably papillary carcinoma, may develop in ectopic thyroid tissue. Carcinomas may also arise in thyroglossal duct cysts, which develop from duct remnants between the foramen cecum and thyroid isthmus. Infectious disease of the thyroid gland is not common and the CT and MR imaging findings are similar as described under neck infection. Other types of inflammatory disorders including Hashimoto's thyroiditis, granulomatous thyroiditis, and Riedel's struma display no specific imaging features. Imaging studies may, however, be indicated to confirm a suspected clinical diagnosis and assess compromise of the airway (Riedel's struma). HPT is a clinical diagnosis in which hypercalcemia is the most important finding. Parathyroid hyperplasia, adenoma, and carcinoma represent underlying lesions. To relieve the patient's symptoms surgical extirpation is indicated. The surgical success rate without imaging is 95%. The indications for imaging studies vary but it is generally agreed that reoperation after a previous failed surgical attempt and suspicion of an ectopic parathyroid adenoma should be investigated by imaging. These consist of US, nuclear medicine studies, CT and MR imaging. US and technetium sestamibi scanning have the highest accuracy rate for localizing an adenomatous gland at and near the thyroid gland. Ectopic adenomas, particularly if they are located in the mediastinum, are preferrably investigated with CT and MR imaging with gadolinium and fat suppression. Carcinomas and parathyroid cysts are optimally evaluated by CT and MR imaging. On MR imaging adenomas are low in signal intensity on T1-weighted images, high in signal intensity on T2-weighted images, and enhance post introduction of gadolinium.

Abstract
Invasion of the larynx and trachea by thyroid cancer is an uncommon but difficult problem. There is no consensus on indication for or extent of surgery, particularly when there is a requirement for airway reconstruction. From 1989 through 1996, we treated 22 patients with thyroid carcinoma with invasion of the larynx and trachea. Seventeen of these patients had recurrent disease. We applied radioactive iodine therapy after regional ablative surgery to resectable tumors with or without lung metastasis, larynx-preserving surgery to extraluminal or small intraluminal tumors restricted to the short segment of trachea, or total laryngectomy to recurrent tumors deeply invading the cartilage framework of the larynx. We performed arytenoid adduction or thyroplasty in one stage if the recurrent laryngeal nerve was paralyzed or resected intraoperatively. We could get relatively good survival and functional results by aggressive surgical treatment in 20 patients, but the disease was inoperable in 2 patients. It is stressed that head and neck surgeons who have to deal with cancer of the thyroid should not only be familiar with various techniques of airway reconstruction and voice rehabilitation but also must be aware of the biologic behavior of the thyroid carcinoma.

Abstract
BACKGROUND The clinical significance of microscopically locoresional-residual differentiated thyroid carcinoma is still an unsolved problem. METHODS Patients who underwent resectional management for advanced differentiated thyroid carcinoma were divided into complete (n = 58), microscopic (n = 37), macroscopic (n = 14), and distant (n = 22) groups. RESULTS Postoperative recurrence was similar in the complete (28%) and microscopic (22%) groups and was significantly lower than that of the macroscopic (57%) and distant (67%) groups. Age, gender, lymph node metastasis, and the residual status (complete and microscopic versus macroscopic and distant) were independent risk factors for recurrence. Postoperative survival of the complete and microscopic groups groups was better than that of the macroscopic and distant groups. Age and the residual status were independent prognostic factors for overall and cause-specific survival. CONCLUSIONS Postoperative recurrence and survival of patients with microscopic residual cancer were similar to those of patients with complete resection, and macroscopic residual cancer either in locoregional or distant loci was an ominous prognostic sign.

Abstract
We retrospectively analyzed the outcome for patients with locally invasive papillary carcinoma. The study group comprised 40 patients with locally invasive papillary thyroid carcinoma first diagnosed between 1981 and 1995. The enrolled patients were divided into two groups according to whether they underwent complete resection (n = 19) or not (n = 21). All patients were followed-up for a maximum of 206 months and a minimum of 33 months until 1998. There were no significant differences among these two groups with regard to age, sex, or tumor size. Recurrence of the disease was recognized in four patients in the complete resection group and ten in the incomplete group. There were no significant differences in the recurrence rate between both groups. Five patients from the incomplete resection group died of disease, and all patients from the complete resection group were alive. The percentage of surviving patients in the complete resection group was significantly higher than that in the incomplete group. The 15-year survival rates of the complete resection group and incomplete resection group were 100% and 74.2%, respectively. The 15-year survival rate of patients younger than 45 years in the incomplete resection group was 100%. The 15-year survival rate of the complete resection group was significantly higher than that of the incomplete group. In conclusion, complete resection without tumor residue should be performed for patients older than 45 years.

Abstract
Extensive local invasion of the trachea or larynx by differentiated thyroid cancer has usually resulted in a conservative therapeutic approach, including at least a thyroid biopsy and external beam irradiation. Thyroidectomy, if performed, has also allowed radioactive iodine administration with variable uptake. Survival rates are rarely reported, but generally considered dismal. In light of this, an aggressive surgical approach was initiated with attempted resection of all local tumor tissue. Seven patients (five females and two males), 38 to 82 years of age (mean, 64), underwent tracheal sleeve resection for obstructing lesions (four patients) or partial laryngectomy (three patients) for locally invasive tumors. Esophageal resections were included in two patients. Follicular cancer was seen in two patients; Hürthle cell cancer was seen in three patients; and papillary cancer was seen in two patients. Patients were also treated with radioactive iodine and external beam irradiation. Patients were followed regularly postoperatively to establish survival. No operative deaths were seen. Two patients died of disease at 57 and 47 months postoperatively. One died of natural causes 24 months after surgery. Four patients are alive at 10, 29, 114, and 118 months after resection. Mean survival, to date, is 51.3 months. Aggressive attempts at surgical resection of differentiated thyroid cancers seems warranted for tumors obstructing the trachea or involving the larynx. It has been well tolerated and is associated with a >4-year average survival. A nihilistic approach no longer can be justified in these patients.

Abstract
Well-differentiated thyroid cancer usually progresses slowly and rarely invades other tissues. However, the rare cases with invasion of local structures, such as the larynx, trachea, or esophagus, present particular management difficulties. In situations with limited involvement of the larynx or trachea, there is controversy over whether a "shave excision" that may leave microscopic disease at the site, or a complete resection that includes removal of a portion of these structures is the better approach. In the case of more extensive involvement of upper aerodigestive tract structures by thyroid carcinomas, the most appropriate method of resection and reconstruction is also at issue. We discuss the literature pertaining to the surgical management of laryngotracheal and esophageal invasion by thyroid carcinoma, review the incidence and presentation of this disease, and make recommendations based on our own experience.

Abstract
Primary malignant tumours of the trachea are extremely rare in infants. This report describes an 11-month-old boy suffering from severe dyspnea with a 5-month history of stridor and 'bronchitis'. A hard mass could be palpated below the right lobe of the thyroid gland. Roentgenograms and endoscopy showed an exophytic tumour filling more than 80% of the tracheal lumen. A tracheal resection and a subtotal thyroidectomy with primary anastomosis was performed. An invasive squamous cell carcinoma of the trachea was diagnosed. This is the first reported case in an infant in the English literature. A local recurrence was found on MRI 19 weeks later. The infant died at 16 months of age.

Abstract
OBJECTIVE This study was undertaken to determine whether the recurrent laryngeal nerve involved in differentiated thyroid carcinoma could be preserved. SUMMARY BACKGROUND DATA Few investigations have provided definitive results concerning preservation of the recurrent laryngeal nerve involved in thyroid cancer. Complete excision with resection of the recurrent laryngeal nerve reportedly did not improve survival over incomplete excision in differentiated thyroid carcinoma. METHODS A retrospective study was performed with the medical records of 50 patients with differentiated carcinoma and preoperative normal vocal cord function to investigate outcomes of recurrent laryngeal nerve preservation including local recurrence, prognosis, and postoperative vocal cord function. The recurrent laryngeal nerves on 1 or both sides were preserved in 23 patients (the preserved group), whereas the involved recurrent laryngeal nerve of the other 27 patients was resected (the resected group). RESULTS Backgrounds of patients were similar between the resected and preserved groups. The number of patients with recurrences in each group was similar, and incidence of local, regional, and distant metastatic recurrences were not different between the groups. Postoperative overall survival of the preserved group was similar to that of the resected group (p = 0.1208). More than 60% of patients or of nerve at risk in the preserved group restored normal vocal cord function within 6 months. Some functional vocal cord movement was recognized in 80% of patients or of nerve at risk. All patients in the resected group including patients with nerve anastomosis showed permanent paralysis of the ipsilateral vocal cord. CONCLUSIONS These results suggested that the recurrent laryngeal nerve, even if infiltrated by differentiated thyroid cancer, is worthwhile to preserve for maintenance of postoperative vocal cord function without affecting the incidence of local recurrence or prognosis.

Abstract
OBJECTIVE Although aggressive approaches to locally invasive differentiated thyroid carcinoma are reported to improve the prognosis, few investigations have provided an indication for airway resection. The present study was undertaken to determine the best indication for airway resection for differentiated thyroid carcinoma invading the trachea. METHODS One hundred seventeen patients with differentiated thyroid carcinoma invading surrounding structures were retrospectively studied for local failures and prognosis and were divided into five groups mainly on the basis of macroscopic findings: Group 1 consisted of 40 patients who underwent tracheal resection for deep tracheal invasion; group 2 consisted of 14 patients with deep tracheal invasion and no airway resection; group 3 consisted of 13 patients with superficial tracheal invasion and no airway resection; group 4 comprised 48 patients with extrathyroidal invasion other than laryngotracheal structures; and group 5 consisted of two patients who underwent tracheal resection for superficial invasion. RESULTS Resectional management of the airway for patients with deep tracheal invasion decreased local recurrence and improved postoperative prognosis compared with nonresectional management for the tumor, or shaving off tumor from the trachea for patients with superficial invasion, did not increase postoperative local failures or mortality (group 3 vs groups 4, 5, and 1). CONCLUSION These results implied that differentiated thyroid carcinomas with superficially limited invasion could be treated successfully by nonresectional management of the trachea and that those with deep invasion should be treated by resection of the invaded trachea.

Abstract
BACKGROUND In view of the indolent nature of most cancers of the thyroid, particularly of the papillary and follicular variety, the decision to remove a segment of the upper aerodigestive tract when the cancer is either close to or invading this area is a difficult one. It was felt relevant to review the experience at the M.D. Anderson Hospital to see when such resections were necessary, how they were repaired, and the survival rates. PATIENTS AND METHODS Of the 1,098 patients with cancers of the thyroid treated surgically at M.D. Anderson Cancer Center from 1954 to 1993, 46 underwent resections of some portion of the upper aerodigestive tract for invasive cancer. These included 35 patients who had histories of prior surgical treatment with or without radiation or radioactive iodine therapy. The operations included 27 total and 5 partial laryngectomies, 1 circumferential and 13 partial resections of the trachea, and 5 circumferential and 10 partial esophagectomies. Several patients had combinations of these procedures. Details of the repairs are provided. Postoperative radiation or radioactive iodine treatment was administered when indicated. RESULTS Local recurrence was infrequent. Most deaths occurred from either pulmonary metastasis or causes other than the cancer. The 5-year survival rate for all patients exceeded 50%. More than 70% of patients with papillary and follicular cancers survived for 5 years, and some for up to 30 years. CONCLUSIONS Although it cannot be stated with any degree of certainty if a resection of a portion of the upper aerodigestive tract should be done at the time of the initial surgical procedure, it is apparent that there are some situations in which the resection should be done because of severe local problems A variety of methods of repair are available, and the survival rate is greater than 50% for all such procedures, with those having the papillary and follicular variety surviving for 5 years in more than 70% of cases. Patients can exist with severe local problems for a number of years and it is sometimes the patient who decides when the resection should be done.

Abstract
Invasion of the upper airway by well-differentiated thyroid carcinoma is very unusual. Treatment is primarily surgical resection, but the extent of the resection has been controversial. Adjuvant treatment using I131 or radiotherapy also has an important role in management. We describe two cases of direct infiltration of the larynx and trachea by well-differentiated thyroid carcinoma and discuss the current recommendations for the management of this difficult problem.

Abstract
We received the clinical and pathologic features of 22 cases of papillary carcinoma of the thyroid that invaded the trachea and were treated by thyroidectomy and airway resection with or without reconstructive surgery over an interval of 16 years. We studied the fine relationships between lamina propria and lymphatics in the region between the isthmus of the thyroid and the trachea. The manner of invasion of papillary carcinoma of the thyroid was by blunt dissection along blood vessels and collagen fibers oriented perpendicularly to the tracheal lumen between cartilaginous rings. Although lymph node metastases were found in 14 patients (64%), we observed lymphangitic tumor in the tracheal mucosa in only three patients (14%). We devised a staging system for papillary carcinoma of the thyroid based on the extent of invasion of the trachea. Of the 11 patients with stage I, II, or III disease, none of six (0%) followed for 5 years died of thyroid cancer in the 5-year observation period; one patient in this group died later of thyroid cancer. Of the 11 patients with stage IV disease, five of seven (71%) followed for 5 years died of thyroid cancer in the 5-year observation period; one additional patient in this group died later of thyroid cancer.
