The impact of nodal status in major salivary gland carcinoma: A multicenter experience and proposal of a novel N-classification.

Objectives: Despite differences in oncological behavior, the 8th edition of AJCC TNM staging currently proposes the same N-classification for major salivary glands (MSG) carcinoma and squamous cell carcinoma of the upper aerodigestive tract. The present study aims to investigate a more reliable definition of N-categories for MSG carcinoma.

Materials And Methods: A retrospective multicenter study was performed, including 307 patients treated for primary MSG carcinoma from 1995 to 2019.

Mendelian randomization supports a causative effect of TSH on thyroid carcinoma.

Evidence from observational studies suggest a positive association between serum thyroid-stimulating hormone (TSH) levels and differentiated thyroid carcinoma. However, the cause-effect relationship is poorly understood and these studies are susceptible to bias and confounding. This study aimed to investigate the causal role of TSH in both benign thyroid nodules and thyroid cancer in up to 451,025 UK Biobank participants, using a genetic technique, known as Mendelian randomization (MR).

Does Obesity Cause Thyroid Cancer? A Mendelian Randomization Study.

Background: The incidence of thyroid cancer is rising, and relatively little is known about modifiable risk factors for the condition. Observational studies have suggested a link between adiposity and thyroid cancer; however, these are subject to confounding and reverse causality. Here, we used data from the UK Biobank and Mendelian randomization approaches to investigate whether adiposity causes benign nodular thyroid disease and differentiated thyroid cancer.

Controversies in the surgical management of sporadic medullary thyroid carcinoma.

Purpose Of Review: Medullary thyroid carcinoma (MTC) represents a wide spectrum of tumours with differing biology, behaviour and natural history. The only current available curative treatment is surgery in the form of thyroidectomy with or without ipsilateral or bilateral neck dissection. There is a lack of consensus in the available published guidelines on the optimum extent of initial surgery, and there is significant variation in clinical practice.

The diagnostic value of cytology in parotid Warthin's tumors: international multicenter series.

Introduction: Warthin's tumor (WT) is a common benign salivary gland neoplasm with a negligible risk of malignant transformation. However, there is a risk of malignant tumors being misdiagnosed as WT on cytology and inappropriately managed conservatively.

Methods: Patients from nine centers in Italy and the United Kingdom undergoing parotid surgery for cytologically diagnosed WT were included in this multicenter retrospective series.

The role of molecular genetics in the clinical management of sporadic medullary thyroid carcinoma: A systematic review.

Background: The significant variation in the clinical behaviour of sporadic medullary thyroid carcinoma (sMTC) causes uncertainty when planning the management of these patients. Several tumour genetic and epigenetic markers have been described, but their clinical usefulness remains unclear. The aim of this review was to evaluate the evidence for the use of molecular genetic and epigenetic profiles in the risk stratification and management of sMTC.

Clinical outcomes following Cochlear™ BIA300 bone anchored hearing aid implantation in children.

Objective: Bone anchored hearing implants (BAHI) have been in use for over 30 years, and are commonly implanted in children for a range of indications. The Cochlear™ BIA300 system was launched in 2010 and used at The Birmingham Children's Hospital from 2011. Here we report the long-term outcomes of children implanted with the Cochlear™ BIA300 BAHI system in our centre.

The Clinical Utility of Cell-Free DNA Measurement in Differentiated Thyroid Cancer: A Systematic Review.

Background: Cell-free DNA (cfDNA) can be detected in the circulation of healthy individuals, but is found in higher concentrations in cancer patients. Furthermore, mutations in tumor cells can be identified in circulating DNA fragments. This has been the subject of significant interest in the field of cancer research, but little has been published in thyroid cancer.

Thyroid-stimulating hormone suppression therapy for differentiated thyroid cancer: The role for a combined T3/T4 approach.

Background: In the management of differentiated thyroid carcinoma, surgery with or without postoperative radioiodine, and thyroid-stimulating hormone (TSH) suppression is the standard of care in most patients. Levothyroxine is recommended for long-term TSH suppression. For some patients, this may be difficult to tolerate due to adverse effects, such as impaired cognitive function.

External beam radiotherapy in differentiated thyroid carcinoma: A systematic review.

External beam radiotherapy (EBRT) is not a first line treatment in differentiated thyroid carcinoma (DTC), but is recommended as an adjuvant treatment in certain cases. The evidence for EBRT in DTC is limited. A comprehensive literature search was performed.

Successful management of a catecholamine-secreting glomus jugulare tumor with radiosurgery alone.

Secretory glomus jugulare tumors are often resected surgically to control the systemic effects of the catecholamines they produce. This involves complex skull base surgery, which carries significant risks and frequent morbidity. Stereotactic radiosurgery (SRS) is a recently recognized treatment for glomus jugulare tumors, though little is known about its use in secretory tumors.

Vaginoplasty: a modern approach: a report of 2 cases.

Background: Split-thickness skin graft vaginoplasty is one of many methods for vaginal reconstruction. In its 130-year history it has been modified by numerous authors in attempts to improve graft viability and neovaginal function. We describe a modern approach that aims to improve outcomes and reduce complications.
