BACKGROUND: Schwannomas are benign, encapsulated, peripheral nerve tumours that arise from the Schwann cell. Approximately 25%-45% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck. However, schwannoma of the supraglottic oropharynx is rare. CASE PRESENTATION: We report on a 35-year-old female who complained of progressive dysphagia, from whom a large schwannoma in the supraglottic oropharynx was excised through a transoral approach...

PURPOSE: The literature and experience of high-dose-rate (HDR) surface mould brachytherapy (SMB) in head and neck cancer is sparse. We report our institutional experience of SMB for such tumours. MATERIAL AND METHODS: Thirty-five patients with malignant localized early T1/T2, N0 (21 intra-oral and 14 skin) tumours treated with SMB during 2008-2014 were analyzed. Treatment was delivered using HDR (192)Ir source to a median dose of 49 Gy (range, 38.5-52.5 Gy) as radical brachytherapy and 18 Gy (range, 15...

Submandibular gland tumours, especially mesenchymal tumours, are extremely rare. Schwannoma of the salivary gland is a particularly rare form of an extracranial neurogenic tumor, of which ancient schwannoma is one of five variants. Since the first description, only a few ancient schwannomas have been reported in different locations in the head and neck region. In the submandibular gland it is very rare. This report presents a case of 26 year old male patient with an ancient schwannoma of the submandibular gland seems to be arising from parasympathetic fibers...

OBJECTIVES: Lymph node ratio (LNR) is an established predictor in different entities of carcinoma, including head and neck malignancies. In oropharyngeal squamous cell carcinoma (OPSCC), lymph node involvement differs between Human Papilloma Virus (HPV)-positive and negative tumours. Herein, we evaluate the impact of HPV association on the concept of LNR. METHODS: 88 surgically treated patients were included in this retrospective chart review. HPV-positive and negative OPSCC were evaluated for prediction of outcome by LNR separately...

Anaplastic thyroid cancer is the rarest tumour of the thyroid gland, representing only 2% of clinically recognised thyroid cancers. The most common metastatic sites are lungs, followed by the intrathoracic and neck lymph nodes. We report the case of a 62-year-old woman who presented to our setting with multiple soft tissue nodules, thyroid mass, head swelling and weight loss. Radiological investigation showed a large thyroid mass with widespread metastasis in subcutaneous tissues of both upper limbs, chest and abdomen...

BACKGROUND: Radical radiotherapy, with or without concomitant chemotherapy forms the mainstay of organ preservation approaches in mucosal primary head and neck cancer. Despite technical advances in cancer imaging and radiotherapy administration, a significant proportion of patients fail to achieve a complete response to treatment. For those patients who do achieve a complete response, acute and late toxicities remain a cause of morbidity. A critical need therefore exists for imaging biomarkers which are capable of informing patient selection for both treatment intensification and de-escalation strategies...

AIM: To evaluate the interobserver reproducibility of computed tomography (CT) measurements of maximum tumour diameter and tumour volume for head and neck squamous cell carcinoma. MATERIALS AND METHODS: Eighty consecutive patients who underwent neck CT for the initial evaluation of head and neck squamous cell carcinoma were included in this retrospective study. Two radiologists independently measured the maximal axial diameter and volume of tumours. The reproducibility between the two observers was assessed using 95% Bland-Altman limits of agreement, reproducibility coefficient, within-subject coefficient of variation, and intraclass correlation coefficient with subgroup analysis according to tumour location...

REVIEW
Arif Aslam
Microcystic adnexal carcinoma (MAC) is a rare, slow-growing, infiltrative malignant tumour most commonly found on the head and neck. It often presents as a solitary skin-coloured or yellow papule, plaque or nodule. Ultraviolet radiation, immunosuppression and ionising radiation are possible risk factors. Clinical and histological differential diagnoses include morpheaform basal cell carcinoma and desmoplastic trichoepithelioma. The diagnosis is usually made by skin biopsy, and the characteristic features are small keratin-filled cysts with nests and cords which resemble ductal structures...

Complete surgical resection is the only option for improving the survival of patients with ductal adenocarcinoma in the pancreatic head. After resection, determining the status of resection margins (RMs) is crucial for deciding on the nature of the follow-up treatment. The purpose of this study was to evaluate whether multiphoton microscopy (MPM) could be considered a reliable tool for determining the status of pancreatic neck margins by identifying tumour cells of ductal adenocarcinoma in these margins in the pancreatic head, and our results were affirmative...

REVIEW
Paul M Speight, Takashi Takata
The latest (4th) edition of the World Health Organization Classification of Head and Neck tumours has recently been published with a number of significant changes across all tumour sites. In particular, there has been a major attempt to simplify classifications and to use defining criteria which can be used globally in all situations, avoiding wherever possible the use of complex molecular techniques which may not be affordable or widely available. This review summarises the changes in Chapter 8: Odontogenic and maxillofacial bone lesions...

Ameloblastoma is one of the most common benign odontogenic tumours of the mandible and the maxilla. Wide excision of the tumour is the first choice for treatment (except for unicystic ones). Patients with invaded margins or unresectable lesions may require radiotherapy. Today, permanent implantation of I(125) seeds is widely used in the treatment of cancer of the head and neck. We report a case of recurrent ameloblastoma of the base of the skull that was treated with I(125) brachytherapy. The outcome has been encouraging, with total disappearance of the tumour on positron emission tomography 18 months later...

Programmed cell death (PD-1) and its ligand (PD-L1) inhibitors have shown clinical response in many tumours. PD-L1 data are limited in head and neck cutaneous squamous cell carcinoma (HNcSCC) and no clinical trials of PD-1/PD-L1 inhibitors are published. We performed PD-L1 immunohistochemistry on 74 cases of high risk HNcSCC with 38 matched metastases and evaluated clinicopathological associations, prognostic significance and heterogeneity in matched metastases. We observed PD-L1 expression in >5% of primary tumour cells in 29 cases (39...

This study was undertaken to evaluate the association between demographics, lifestyle habits, and clinical data and overall survival (OS), recurrence and second primary cancer (SPC) in patients with first primary head and neck cancer (HNC). We retrospectively reviewed data from 482 patients treated at the "Agostino Gemelli" Teaching Hospital, Rome, between 2002-2012 for primary HNC. Individual parameters were evaluated for association with specific outcomes such as OS, cancer recurrence and second primary cancer (SPC) appearance using hazard ratios (HR) and 95% confidence intervals (CIs)...

Head and neck cutaneous squamous cell carcinoma (HNcSCC) can present with cervical metastases without an obvious primary. Immunohistochemistry for p16 is established as a surrogate marker of human papillomavirus (HPV) in oropharyngeal cancer. p16 expression in HNcSCC needs to be elucidated to determine its utility in predicting the primary site. The aim of this study was to evaluate the rate of p16 expression in HNcSCC and its association with prognostic factors and survival. p16 immunohistochemistry was performed on 166 patients with high risk HNcSCC (2000-2013) following histopathology review...

BACKGROUND: Low density lipoprotein (LDL) receptor-related protein 1 (LRP1) is a ubiquitously expressed multi-ligand endocytosis receptor implicated in a wide range of signalling, among others in tumour biology. Tumour-associated genomic mutations of the LRP1 gene are described, but nothing is known about cancer-associated expression of LRP1 splice variants Therefore, the focus of this study was on an annotated truncated LRP1 splice variant (BC072015.1; NCBI GenBank), referred to as smLRP1, which was initially identified in prostate and lung carcinoma...

INTRODUCTION: The majority of patients with advanced head and neck cancer receiving chemotherapy show partial response or frank resistance. Therefore, assessing the individuals' tumour reactivity to the eligible chemotherapeutic compounds carries the potential of personalizing the patient treatment and minimizing ineffective regimens which lead to excess toxicity and cost, treatment delays and possibly causing the tumour to be cross resistant to additional drugs. AIM: To determine the effectiveness of a phenotypic chemoresponse assay in predicting response to chemotherapy in a retrospective series of head and neck cancer patients whose tumour specimens had been tested with ChemoFx assay (Precision Theraputic Inc...

Schwannomas are benign peripheral nerve sheath tumours that may occur throughout the body. They rarely occur in the nasal cavity. Paranasal schawannomas are uncommon lesions, representing less than 4% of all head and neck schawannomas. Here we report a case of sinonasal schwannoma in a 35-year-old man who presented with a history of nasal blockage since two years. The mass was removed successfully without any postoperative complication and there was no recurrence within a year of follow up.
