The challenges in the risk stratification of thyroid nodules and cancers: the role of molecular testing

Around the world, molecular testing is becoming more widely used to personalise the management of thyroid nodules. Thyroid nodules are relatively common. They are palpable in ~5% of the population, while high-resolution ultrasound (US) incidentally finds them in 19–68% of...

Molecular and genetic nature of skull base tumours drives management

This article reviews the molecular basis and paradigm shift in the diagnosis and management of skull base tumours. It is now known that the phenotype of meningiomas is influenced by their genotype. Endolymphatic sac tumours are observed in up to...

A higher aspiration for fine needles

Fine needle aspiration biopsy (FNAB) has aided in the diagnosis and management of thyroid nodules for decades. Now a rapid evolution is hoped to benefit an increasing cohort of patients with small nodules and non-diagnostic investigations. This review discusses the...

In conversation with Frederik Dikkers

Declan Costello, editor of ENT & Audiology News, has recently enjoyed a couple of conversations with Professor Emeritus Frederik Dikkers that you can now watch on YouTube.

Expanding the role of FNA in thyroid nodule decision-making

Papillary thyroid cancer, the commonest histological type, has been extensively reported as having BRAF proto-oncogene mutations (most commonly the V600E mutation). There is great interest in BRAF as a molecular marker, particularly as a prognostic factor that may guide the...

Amount of dietary iodine and thyroid cancer

Two molecular scientists from Zurich wrote this paper as a systematic review, asking the question of whether dietary iodine intake is a risk factor for developing thyroid cancer later on life. They speculate that low iodine intake is a risk...

Harnessing head and neck cancer genomics for personalised medicine

Luc Morris updates us on the future of cancer diagnosis and treatment, which lies in “personalised oncology”, where specific molecular alterations of each tumour will be identified, and matched with actionable alterations in existing therapies, ushering in the era of...

Investigation of the role of KPNA2 biomarker in oral SCC invasiveness

This edition of Head and Neck has a strong focus on studies using immunohistochemistry (IHC) to elucidate potential roles of various cell-signalling molecules in both HNSCC and thyroid cancer. The ‘cellular-protein heavy’ title of this article may be off-putting to...

The structure and function of DNA

DNA structure and replication Genetic information within multicellular organisms, including man, is stored in molecules of deoxyribonucleic acid (DNA), which reside within the chromosomes of each cell nucleus. A DNA molecule consists of two very long chains, or strands, of...

American Thyroid Association Thyroid Cancer Management Guidelines: utilising risk stratification to optimise patient care

The steep rise in thyroid surgery around the globe, has led to the development of risk stratification to define the indications for surgery and the extent of surgery as well as adjuvant therapies for papillary carcinoma, to avoid over treatment....

Resection margins in head and neck surgery

Although an increasing proportion of head and neck malignancies are treated with non-surgical modalities, when surgery is undertaken an incomplete clearance results in significantly worse prognosis. However, the intraoperative assessment of an adequate margin is difficult. The personal practice of...

Follicle stimulating hormone receptors; an aid for the pathologist?

It is well known that Follicle Stimulating Hormone receptors (FSHRs) are found in extra-gonadal tumours such as those within thyroid tissue. This Polish study analysed 44 thyroid resection specimens to look for the presence of these receptors. No mention is...
