Perineural spread of tumour cells along cranial nerves is a severe complication of primary cutaneous squamous cell carcinomas of the head and neck region. While surgical excision of the tumour is the treatment of choice, removal of all the tumour is often complicated by the neural location and recurrence is frequent. Non-invasive immune treatments such as checkpoint inhibitor blockade may be useful in this set of tumours although little is understood about the immune response to perineural spread of squamous cell carcinomas...

Oral cavity cancer belongs to head-and-neck squamous cell carcinoma group. The purpose of the study was to assess the levels of certain proteins in a tumour and surgical margin in a group of patients with oral cavity cancer. The levels of DAPK1, MGMT, CDH1, SFRP1, SFRP2, RORA, TIMP3, p16, APC and RASSF1 proteins were measured by ELISA in tissue homogenates. The protein levels of DAPK1, MGMT, CDH1, SFRP2 and RASSF1 were significantly higher in tumour tissue than in the margin, contrary to TIMP3 which was lower in the tumour itself...

Cervical lymph node metastasis affects the prognosis and overall survival rate of and therapeutic planning for patients with head and neck squamous cell carcinomas (HNSCCs). However, advanced diagnostic modalities still lack accuracy in detecting occult neck metastasis. A sentinel lymph node biopsy is a minimally invasive auxiliary method for assessing the presence of occult metastatic disease in a patient with a clinically negative neck. This technique increases the specificity of neck dissection and thus reduces morbidity among oral cancer patients...

BACKGROUND: Head and neck paragangliomas are rare. They are usually slow-growing, benign, non-catecholamine secreting tumours, traditionally treated with surgical excision. Complications of surgical excision include lower cranial nerve palsies, stroke and death. METHOD: A retrospective case note analysis was conducted of patients with head and neck paragangliomas treated with a watch-and-scan policy from March 2003 to September 2015, and the relevant literature was reviewed...

BACKGROUND: Planned neck dissection (ND) after radical chemoradiotherapy (CRT) for locally advanced nodal metastases in patients with head and neck squamous cell carcinoma (HNSCC) remains controversial. Thirty per cent of ND specimens show histological evidence of tumour. Consequently, a significant proportion of clinicians still practise planned ND. Fludeoxyglucose positron emission tomography (PET)-computerised tomography (CT) scanning demonstrated high negative predictive values for persistent nodal disease, providing a possible alternative paradigm to ND...

Radionecrosis is a late, and difficult to treat,complication of radiotherapy performed on head and neck tumours, and it is difficult to treat. This process causes significant damage, not only in the skin, but also in muscular, nervous, vascular, and bone structures. This, in turn, leads to airway and digestive tract involvement, as well as a functional loss and a cosmetic defect that usually requires reconstructive surgery. Therefore, this process is associated with a significant loss in the quality of life of patients and involves a long hospital stay for treatment, as well as the necessary support measures...

Immature myeloid cells including myeloid-derived suppressor cells (MDSCs) and tumour-associated macrophages (TAMs) promote tumour growth and metastasis by facilitating tumour transformation and angiogenesis, as well as by suppressing antitumour effector immune responses. Therefore, strategies designed to reduce MDSCs and TAMs accumulation and their activities are potentially valuable therapeutic goals. In this study, we show that negative immune checkpoint molecule B7-H3 is significantly overexpressed in human head and neck squamous cell carcinoma (HNSCC) specimen as compared with normal oral mucosa...

INTRODUCTION: Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed...

Neurofibroma (NF) is a benign tumor of the peripheral nervous system. Head and neck NF are generally located in the soft tissue. The tumour is rarely seen intraosseously and most commonly such tumours are seen as solitary lesions, rather than part of neurofibromatosis. The following report describes a case of an intraosseous neurofibroma in a 45-year-old male located in the left posterior mandible. The diagnosis was made based on the clinical findings, radio graphical features, histopathology, and immunohistochemistry...

INTRODUCTION: Squamous Cell Carcinoma (SCC) is an aggressive epithelial malignancy of the upper aero digestive tract and comprises 90% of all Head and Neck Squamous Cell Carcinoma (HNSCC). It is the sixth leading cancer worldwide with approximately 600,000 cases reported annually. It is one of the most common cancers in India. Tumour Lymph Node and Metastases (TNM) staging has been the most useful indicator to predict prognosis in HNSCC but recently various biomolecular markers have potentially offered new methods for early diagnosis and treatment alternatives for HNSCC patients; one amongst them being cyclin D1...

BACKGROUND: Head and neck squamous cell carcinomas (HNSCCs) represent a heterogeneous group of cancers for which human papilloma virus (HPV) infection is an emerging risk factor. Previous studies showed promoter hypermethylation in HPV(+) oropharyngeal cancers, but only few consistent target genes have been so far described, and the evidence of a functional impact on gene expression is still limited. METHODS: We performed global and stratified pooled analyses of epigenome-wide data in HNSCCs based on the Illumina HumanMethylation450 bead-array data in order to identify tissue-specific components and common viral epigenetic targets in HPV-associated tumours...

BACKGROUND: Giant cell tumors (GCTs) are typically found in the metaphyseal-epiphyseal area of long bones but can also occur in the head and neck region. GCT of the larynx is a rare entity with only 42 reported cases in the international literature. Furthermore, to the best of our knowledge this is the largest laryngeal GCT reported in the literature to date. GCT of the larynx can present with dysphonia, dyspnea, and/or dysphagia and should be considered in the differential diagnosis of a neck mass...

REVIEW
Patricia Jaaks, Michele Bernasconi
Proprotein convertases are proteases that have been implicated in the activation of a wide variety of proteins. These proteins are generally synthesised as precursor proteins and require limited proteolysis for conversion into their mature bioactive counterparts. Many of these proteins, including metalloproteases, growth factors and their receptors or adhesion molecules, have been shown to facilitate tumour formation and progression. Hence, this review will focus on the proprotein convertase furin and its role in cancer...

Head and neck hard tissue sarcomas form a rare group of mesenchymal derived tumours that comprise less than 1% of all head and neck neoplasms. Hard tissue sarcomas account for 20% of head and neck sarcomas and they form a heterogeneous group with a diverse origin. Unlike head and neck soft tissue sarcomas, they have lower recurrence and mortality rates. In this article, we review the current management of head and neck hard tissue sarcomas.

Infantile haemangiomas (IHs) are the most common congenital vascular tumours of infancy. Propranolol has been demonstrated to be effective for IHs; however, the factors affecting its therapeutic effect remain unknown. We enrolled 169 infants with IHs of the head and neck region treated with oral propranolol at a dose of 2.0 mg/kg/day. We evaluated the therapeutic responses 6 months after treatment and the end of treatment, which were categorized into four grades. The type and location of the lesions and the infant age at treatment initiation were analysed...
