INTRODUCTION AND OBJECTIVES: Extranodal extension in nodal metastases is an independent adverse prognostic factor in head and neck squamous cell carcinoma patients. However, few studies specifically address the subgroup of patients with no clinical evidence of nodal disease. MATERIAL AND METHODS: We retrospectively analysed data from 348 head and neck squamous cell carcinoma patients without any previous treatment and lacking clinical or radiological evidence of neck node metastases during the initial workup, treated with an elective neck dissection between 1992-2014...

Posterior pharyngeal wall squamous cell carcinomas (SCCs) are rare and have an associated poor prognosis. Progress in transoral resection techniques, in particular, transoral robotic surgery (TORS), have renewed the role of surgery in their treatment. This article presents the oncological and functional results obtained by the French Group of Head and Neck Robotic Surgery for TORS for posterior pharyngeal wall SCC-curative surgery. This retrospective, multicentre study presents data collected between September 2009 and November 2013 for patients treated with TORS for posterior pharyngeal wall SCCs...

INTRODUCTION: Tumours of the parapharyngeal space are rare. Only 0.5% of head and neck tumours occur in this space. Surgical excision of parapharyngeal space lesions is challenging because of the anatomical complexity of the area. PRESENTATION OF CASE: A 31-year-old male patient was referred by his general dental practitioner for removal of lower wisdom teeth due to multiple episodes of pericoronitis. At the initial examination, an incidental finding was made of a large fluctuant posterior oropharyngeal swelling...

A stressful event may be sufficient to challenge a strongly held set of assumptions about the world and the self. In some people this may lead to post-traumatic stress disorder (PTSD) and in others to positive psychological change (PPC), whereby a person's reactions to the challenge are beneficial. Little research has investigated PPC in people who have had head and neck cancer (HNC). The aim of this study was to identify demographic, clinical, and psychological factors associated with PPC over time. A cross-sequential study collected data over 5 years...

REVIEW
T A Szyszko, G J R Cook
Combined 2-[(18)F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET)/computed tomography (CT) has an established role in the staging of difficult cases of head and neck (HN) squamous cell carcinoma (SCC), looking for an unknown primary, assessing response post-chemotherapy at 3-6 months, and differentiating relapse from treatment effects in patients suspected to have tumour recurrence. The PET NECK trial, comparing PET/CT surveillance versus neck dissection in advanced head and neck cancer showed survival was similar among patients who underwent PET/CT-guided surveillance and those who underwent planned neck dissection, but surveillance was more cost-effective...

Radiotherapy is the major form of treatment for head and neck carcinoma, a malignant tumour of epithelial origin. The identification of agents, which can be co‑administered in order to sensitize these tumours to radiotherapy, has become a major focus of investigations. In the present study, a novel 20 nm nanocomposite, Ag/C225, was constructed, which consisted of silver nanoparticles (AgNPs) conjugated to an epidermal growth factor receptor‑specific antibody (C225). Physical characterization demonstrated that the Ag/C225 nanoparticles were spherical and dispersed well in water...

BACKGROUND AND PURPOSE: Defining margins around the Gross Tumour Volume (GTV) to create a Clinical Target Volume (CTV) for head and neck cancer radiotherapy has traditionally been based on presumed knowledge of anatomical routes of spread. However, using a concentric geometric expansion around the GTV may be more reproducible. The purpose of this study was to analyse the inter-observer consistency of geometric CTV delineation with adaptation for anatomical boundaries versus anatomically defined CTVs...

One challenging feature of head and neck pathology is that a dizzying array of spindle cell lesions occurs here which ranges all the way from reactive, very aggressive forms to malignant lesions. Leiomyosarcoma is one such malignant tumour of mesenchymal origin exhibiting smooth muscle differentiation; presenting generally nonspecific signs and symptoms. Here we present a case of leiomyosarcoma in a 21 year old female patient associated with single reddish pink swelling present in the posterior right maxillary tuberosity region with moderate facial asymmetry...

Context: The co-occurrence of phaeochromocytoma and renal tumours was linked to the inherited familial cancer syndrome von Hippel-Lindau (VHL) disease over six decades ago. Subsequently, other shared genetic causes of predisposition to renal tumours and to phaeochromocytoma (PC), paraganglioma (PGL) or head and neck paraganglioma (HNPGL) have been described but case series of non-VHL-related cases of renal tumour and phaeochromocytoma/paraganglioma tumour association syndrome (RAPTAS), are rare...

Mucoepidermoid carcinoma (MEC) is the most common malignancy of the salivary glands. The clinical behaviour of MEC is largely unpredictable, ranging from indolent tumour growth to highly aggressive metastatic spread. The objective of this study was to determine the clinicopathological predictors of recurrence and survival in patients with head and neck MEC. The medical records of 64 patients who underwent surgical treatment for head and neck MEC between 1982 and 2010 were reviewed. The main outcome measures were disease-free survival (DFS) and overall survival (OS)...

Radiation is a highly efficient therapy in squamous head and neck carcinoma (HNSCC) treatment. However, local recurrence and metastasis are common complications. Recent evidence shows that cancer-cell-derived exosomes modify tumour cell movement and metastasis. In this study, we link radiation-induced changes of exosomes to their ability to promote migration of recipient HNSCC cells. We demonstrate that exosomes isolated from irradiated donor cells boost the motility of the HNSCC cells BHY and FaDu. Molecular data identified enhanced AKT-signalling, manifested through increased phospho-mTOR, phospho-rpS6 and MMP2/9 protease activity, as underlying mechanism...

Adenoid cystic carcinoma is a very rare malignancy commonly originating from the salivary glands of the head and neck. It is again very scantily seen in sites like the bronchus. Surgical resection is the mainstay of treatment but many a times the tumour site and size preclude a favourable outcome of surgery and the patient is advised for other forms of local treatment like Radiotherapy. Here, we present a case report of a young female with primary adenoid cystic carcinoma of the bronchus. The tumour was located in the carina and the left bronchus which was obstructing the airway resulting in collapse of the left lung, this resulted in shifting the mediastinum and abdominal structures in to the thorax...

BACKGROUND: Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade tumour of salivary glands that was first described as a distinct entity in 1994 by Milchgrub et al. EWSR1-ATF1 fusion was found to be specific for this tumour. The majority of the reported cases of HCCC arise from minor salivary glands within the oral cavity. Primary HCCC of the paranasal sinus is extremely uncommon. To our knowledge, only three cases have been reported in the English literature. Herein, we present a case of HCCC of the posterior ethmoid/maxillary sinus...
