Head and neck mucosal melanoma (HNMuM), which occurs mostly in the sinonasal and oral cavity, constitutes less than 1% of all malignant melanomas. Treatment options fail to improve the prognosis of this aggressive tumour that has low overall survival rates. Thus, development of new targeted therapies is essential. Unfortunately, limited data exist regarding their molecular profile. BRAF, NRAS, KIT, TERT and GNAQ/GNA11 oncogene mutations were investigated in 42 HNMuMs (28 sinonasal, 13 oral, 1 nasopharyngeal)...

Cutaneous adnexal tumours encompass a wide group of lesions with apocrine, eccrine, follicular, sebaceous and mixed differentiation. The large majority are benign and represent sporadic lesions, though malignant forms are occasionally encountered and some cases develop in the setting of inherited tumour syndromes. Accurate histological classification can be difficult as there are numerous histological appearances, many of which are individually uncommon, and complex, overlapping and historically variable nomenclature is typical...

OBJECTIVE: To investigate the impact of the tumour volume, HPV status, cancer stem cell (CSC) marker expression and hypoxia gene signatures, as potential markers of radiobiological mechanisms of radioresistance, in a contemporary cohort of patients with locally advanced head and neck squamous cell carcinoma (HNSCC), who received primary radiochemotherapy (RCTx). MATERIALS AND METHODS: For 158 patients with locally advanced HNSCC of the oral cavity, oropharynx or hypopharynx who were treated at six DKTK partner sites, the impact of tumour volume, HPV DNA, p16 overexpression, p53 expression, CSC marker expression and hypoxia-associated gene signatures on outcome of primary RCTx was retrospectively analyzed...

Primary tumour volume evaluation has predictive value for estimating survival outcomes. Using volumetric data acquired by MRI in patients undergoing induction chemotherapy (IC) these outcomes were estimated before the radiotherapy course in head and neck cancer (HNC) patients. MRI performed before and after IC in 36 locally advanced HNC patients were analysed to measure primary tumour volume. The two volumes were correlated using the linear-log ratio (LLR) between the volume in the first MRI and the volume in the second...

Human papillomavirus (HPV), especially HPV16 genotype, is associated with oropharyngeal squamous cell carcinoma (OPSCC). We aim to determine the prevalence and characterize the high-risk (HR)-HPV genotypes in head and neck SCC (HNSCC) in a South-East Asian multi-ethnic society in Singapore and examine its prognostic significance.159 HNSCC archival tissue samples were retrieved and tumour DNA was screened for 18 HR-HPV genotypes using a PCR-based assay (Qiagen, digene HPV genotyping RH test). P16 protein overexpression was identified using immunohistochemistry (IHC)...

BACKGROUND: Human papillomavirus (HPV) is a critical element in the rising incidence of oropharyngeal squamous cell carcinoma (OPSCC), although whether this trend will continue, and the types of HPV responsible, are currently unknown. We previously demonstrated an increased incidence of HPV-related OPSCC in the high HPV prevalence area of Eastern Denmark from 2000 to 2010. Therefore, we investigated if the incidence for OPSCC continued to rise, the association to HPV and putative HPV-types in Eastern Denmark from 2011 to 14...

BACKGROUND: Patients with head and neck squamous cell carcinoma (HNSCC) undergoing radical chemo-radiation (CRT) frequently receive transfusion with packed red cells (PRCT) during radiotherapy on the basis that PRCT increases tumour oxygenation and overcomes hypoxia-induced radio-resistance. This is likely to be a significant oversimplification given the fact that tumour hypoxia is the result of several intrinsic and extrinsic factors, including many that are not directly related to serum haemoglobin (Hb)...

BACKGROUND: Neck metastasis is the most important prognostic factor in oral cavity squamous cell carcinomas (SCC). Apart from the T- stage, depth of invasion has been used as a highly predictable factor for microscopic neck metastasis, despite the controversy on the exact depth cut off point. Depth of invasion can be determined clinically and radio logically. However, there is no standard tool to determine depth of invasion preoperatively. Although MRI is used widely to stage the head and neck disease, its utility in depth evaluation has not formally been assessed...

Trichilemmal carcinoma (TC) is described as a very rare cancer of the skin adnexa.(1 2) Ninety per cent of the lesions present on the scalp. Prognostic factors in TC are limited to lymph node status and surgical margins, with no statistical significance observed for age or gender of the patient, size of tumour or locoregional recurrence. We present a 46-year-old black patient who developed TC during treatment for breast cancer. Postoperative histology of the scalp lesion excision confirmed no involved margins...

Vertebral metastases from primary head and neck cancers are uncommon, and so there are no clear guidelines about management. The spinal cord can be compressed by a vertebral fracture or invasion of a tumour, and may present as an oncological and spinal emergency. The goals of treatment are to relieve pain and maintain neurological function. However, surgical treatments in this group of patients have not been defined, and primary operative treatment of spinal metastases remains controversial. Here we discuss their contemporary management...

Primary mucosal melanomas of the head and neck are rare and aggressive tumours that arise in the nasal cavity, paranasal sinuses and more rarely, in the oral cavity. The current treatment options include radical surgical resection with adjuvant external beam radiotherapy being offered in high risk patients. Although the latter can improve regional control, it does not reduce overall survival. Elective neck dissection is recommended for nodular oral mucosal melanoma but its role in the clinically node negative neck is controversial...

Perineural invasion (PNI) hinders the ability to establish local control of oral squamous cell carcinoma (OSCC). To date, PNI can be evaluated only in surgical specimens and not in preoperative biopsy material, rendering timely therapeutic planning impossible. Insulin-like growth factor-II mRNA binding protein-3 (IMP3) expression appears to be of diagnostic and prognostic utility for many solid tumours, and laminin-5 expression in surgical specimens has been identified as a valid predictor of neural spread of head-and-neck neoplasms...

BACKGROUND: Head and neck cancer of unknown primary (HNCUP) is a source of diagnostic uncertainty. Patients presenting with cytologically positive neck lumps without a clinically identifiable primary, require extensive investigation including imaging, tonsillectomy, panendoscopy and tissue biopsy. Treatment typically involves neck dissection, wide field radiotherapy and chemotherapy. Transoral robotic surgery (TORS) has emerged as an expanding surgical technique for resecting tumours of the oropharynx...

BACKGROUND: Evaluation of resection margins during cancer surgery can be challenging, often resulting in incomplete tumour removal. Fluorescence-guided surgery (FGS) aims to aid the surgeon to visualize tumours and resection margins during surgery. FGS relies on a clinically applicable imaging system in combination with a specific tumour-targeting contrast agent. In this study EpCAM (epithelial cell adhesion molecule) is evaluated as target for FGS in combination with the novel Artemis imaging system...

INTRODUCTION: Head and neck sarcomas are rare and difficult to manage surgically. Factors that influence the prognosis include the type and grade of tumour, resection margins, the anatomical site and patient-specific parameters. We review our experience as plastic surgeons working in a bone and soft-tissue tumour multidisciplinary team (MDT) in managing these tumours surgically. METHODS: Data on all patients with sarcoma of the head or neck managed surgically from 2004 to 2015 was reviewed...

D-dimer level in cancer patients is associated with risk of venous thromboembolism and deep venous thrombosis. Most cancer patients have "abnormal" D-dimer levels based on the current normal reference range. To investigate tumor-specific D-dimer reference range, we compared D-dimer levels for nine different tumour types with healthy controls by using simultaneous quantile regression and constructing a median, 5th percentile, and 95th percentile model of normal tumour D-dimer concentration. Associations with tumour primary site, stage, pathological type, and treatment were also explored...

Changes in patient anatomy may occur either from a tumour volume, position or function of a specific organ at risk, or target volume, weight loss or a reduction in postoperative oedema, and may vary between patients. Adaptive radiotherapy aims to correct morphological variations by realizing one or more plans during the treatment course. Imaging is used to detect these variations, thereby deciding on a potential replanning. At present, adaptive radiotherapy for head neck cancer (HNC) mainly deals with treatment response, such as weight loss or tumor shrinkage...
