We performed a case-control study to characterize the dose-volume relationship and other variables leading to hypothyroidism after head and neck (H&N) cancer radiation therapy (RT) in a homogenous Veterans Affairs (VA) population. All records of patients receiving RT for various H&N cancers at a single VA medical center between 2007 and 2013 (n = 143) were screened for post-RT thyroid stimulating hormone (TSH) levels (n = 77). The thyroid gland was contoured on each slice of the planning computed tomography scan when available (hypothyroid: n = 18; euthyroid > 2 years: n = 16), and dose-volume histograms based on physical dose and biologically equivalent dose (BED) were compared systematically to find the significant dose-volume thresholds that distinguish the patients who developed clinical hypothyroidism...

BACKGROUND: Age is an important prognostic factor in papillary thyroid cancer (PTC), with better survival observed in patients < 45 years of age, regardless of stage. Although the impact of increasing age on PTC-related survival is well-known, previous studies have focused on survival relative to age 45 years only. As the number of patients entering their 7th decade of life increases, PTC-related survival in this demographic becomes increasingly important. Survival in patients ≥ 60 years specifically compared to other groups has not previously been examined...

OBJECTIVE: To establish the long term outcomes of risk stratified management of differentiated thyroid cancer (DTC). BACKGROUND: Guidelines for management of DTC lack a strong evidence base and expose patients to overtreatment. This prospective study of patients diagnosed with DTC between 1977 and 2012 describes the long term outcomes of a conservative risk stratified (AMES) management policy. METHODS: Outcomes were analysed around patient and tumour characteristics, primary intervention (surgery ± radioiodine (RAI)), in terms of mortality, recurrence and reintervention...

BACKGROUND: An elevated thyroid stimulating hormone (TSH) level is essential for the uptake of radioiodine into thyroid remnants and residual thyroid cancer in patients undergoing high-dose radioiodine therapy (HD-RIT). Recently, the use of recombinant human thyroid stimulating hormone (rh- TSH) has increased in preference over the conventional method of thyroid hormone withdrawal (THW). However, the clinical influences of the two methods, aside from the therapeutic effects, have not been widely evaluated...

PURPOSE: Current guidelines recommend thyroid hormone withdrawal (THW) of 3-4 weeks before radioiodine remnant ablation (RRA) of differentiated thyroid carcinoma (DTC). We aimed to evaluate (1) the reliability of a shorter THW (i.e., 14 days) to achieve adequate TSH levels (i.e., 30 mU/l), (2) the association between length of THW and response to therapy, and (3) the potential association between pre-ablation TSH levels and patients' outcome. METHODS: After thyroidectomy, all patients started LT4 therapy, which was subsequently discontinued in order to perform RRA...

BACKGROUND: Papillary thyroid carcinoma with squamous differentiation (PTC-SD) is a poorly understood pathologic finding of unknown clinical significance. Selected case reports have suggested that PTC-SD is an aggressive tumor with a poor prognosis. Here we present the largest case series of PTC-SD reported in the United States. MATERIALS AND METHODS: The cancer registry at our tertiary care referral center was reviewed to identify all patients from 1995-2015 who had been diagnosed with PTC-SD on initial total thyroidectomy or lymph node dissection for recurrent disease...

BACKGROUND: No guidelines exist regarding physicians' duty to inform former patients about novel genetic tests that may be medically beneficial. Research on the feasibility and efficacy of disseminating information and patient opinions on this topic is limited. METHODS: Adult patients treated at our institution from 1950 to 2010 for medullary thyroid cancer, pheochromocytoma, or paraganglioma were included if their history suggested being at-risk for a hereditary syndrome but genetic risk assessment would be incomplete by current standards...

Pathogenic germline DICER1 variants cause a hereditary cancer predisposition syndrome with a variety of manifestations. In addition to conferring increased cancer risks for pleuropulmonary blastoma (PPB) and ovarian sex cord-stromal tumors, particularly Sertoli-Leydig cell tumor, individuals with pathogenic germline DICER1 variants may also develop lung cysts, cystic nephroma, renal sarcoma and Wilms tumor, nodular hyperplasia of the thyroid, nasal chondromesenchymal hamartoma, ciliary body medulloepithelioma, genitourinary embryonal rhabdomyosarcoma and brain tumors including pineoblastoma and pituitary blastoma...

AIM: Solitary cystic masses of the lateral neck in an adult patient can pose a diagnostic dilemma. Malignancy must be ruled out since metastases arising from H&N cancers may mimic the presentation of benign cystic masses. Only a small number of studies have investigated the diagnostic management and malignancy rate of clinically benign solitary cervical cystic lesions. There are no established guidelines for the diagnostic evaluation. METHODS: Retrospective review of the clinical, cytological, radiological, and pathological records of all adult patients (> 18 years) operated on for second branchial cleft cysts (BrCC) between 1/2008-2010/2016...

PURPOSE: Neuroendocrine tumors (NETs) are heterogeneous tumors that arise from the neuroendocrine cells of the digestive tract and other organs, such as the lung, ovary, and thyroid glands. They can be well differentiated or poorly differentiated, and management of these tumors differs for each histologic subtype. We have performed a review of NETs and focused on management of well-differentiated gastroenteropancreatic neuroendocrine tumors (GEPNETs) and carcinoid syndrome. METHODS: A PubMed search was performed to obtain articles on the management of well-differentiated NETs...

Thyroid carcinoma is one of the leading malignancies in Thailand increasingly prevalent in the female population. Fine-needle aspiration (FNA) cytology is a widely used diagnostic tool for evaluation of thyroid nodules and thyroid cancer. Thyroid FNA is a routine procedure universally performed in Thai hospitals by a variety of clinical specialists. Manual guidance is the first-line choice complemented by ultrasound assistance in selected cases. Despite national guidelines recommendations, the diagnostic criteria and terminology of the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) was slowly adopted in the local settings...

BACKGROUND: Indeterminate categories of thyroid cytopathology (categories B-III and B-IV of the Bethesda system) are integrated by a heterogeneous spectrum of cytological scenarios that are generally clustered for analysis and management recommendations. It has been suggested that aspirates exhibiting nuclear atypia have a higher risk of malignancy. This study aimed to assess whether cytologically indeterminate thyroid nodules with nuclear atypia have a significantly higher cancer risk than those without nuclear atypia...

Follicular thyroid cancer is the second most common differentiated thyroid cancer histological type and has been overshadowed by its more common counterpart-papillary thyroid cancer-despite its unique biological behaviour and less favourable outcomes. In this Review, we comprehensively review the literature on follicular thyroid cancer to provide an evidence-based guide to the management of these tumours, to highlight the lack of evidence behind guideline recommendations, and to identify changes and challenges over the past decades in diagnosis, prognosis, and treatment...

BACKGROUND: Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to many extensive malignant airway stenosis patients, such as those with esophageal cancer, lung cancer, and laryngeal cancer...

The introduction of high-efficacy therapies for relapsing-remitting multiple sclerosis has driven re-evaluation of treatment goals and benefit:risk considerations in treatment choice. In the alemtuzumab Phase II and III clinical trials, patients treated with alemtuzumab 12 mg versus subcutaneous interferon beta-1a demonstrated significantly reduced annualized relapse rates and improved magnetic resonance imaging outcomes, and were significantly more likely to achieve no evidence of disease activity and reduction in brain volume loss...

Importance: Venous thromboembolism (VTE), which includes deep venous thrombosis or pulmonary embolism, is the number 1 cause of preventable death in surgical patients. Current guidelines from the American College of Chest Physicians provide VTE prevention recommendations that are specific to individual surgical subspecialties; however, no guidelines exist for otolaryngology. Objective: To examine the rate of VTE for various otolaryngology procedures compared with an established average-risk field (general surgery) and low-risk field (plastic surgery)...
