The vast majority of head and neck cancers (HNCs) are sporadic squamous cell carcinomas, smoking and heavy drinking being the main risk factors. However, little is known about the possible role of family history and the importance of inherited factors versus shared environment. We used Swedish population-based registries to study the family history of HNC. In order to estimate the risk for family members to get the same cancer, and the risk for cancer-specific death in patients with a family history of HNC compared with patients without a family history, multivariate Cox proportional hazards analyses were performed...

Conventional treatment strategies have done little to improve the prognosis or disease-free survival in head and neck cancer (HNC) patients. Recent progress in our understanding of molecular aspects of head and neck squamous cell carcinoma (HNSCC) has provided insights into the potential use of molecular targeted therapies in combination with current treatment strategies. Here we review the current understanding of treatment modalities for both HPV-positive and HPV-negative HNSCCs with the potential to use gene editing and silencing technologies therapeutically...

Intravoxel incoherent motion (IVIM) imaging is increasingly applied in the assessment of head and neck cancer (HNC). Our purpose was to determine the diagnostic and prognostic performance of IVIM in HNC by performing a critical review of the literature. Pubmed and EMBASE were searched until May 2016. Study and patients characteristics, imaging protocol and diagnostic or prognostic outcomes were extracted by 2 independent reviewers. The studied IVIM parameters were diffusion coefficient (D), pseudodiffusion coefficient (D∗), and perfusion fraction (f)...

BACKGROUND: Human papillomavirus (HPV) is now known to cause a significant proportion of head and neck cancers (HNC). Qualitative research has shown that some health professionals find it difficult to discuss HPV with patients due to its sexually transmitted nature, and have concerns about their own knowledge of the virus. We used a survey to quantify attitudes towards discussing HPV among HNC health professionals. METHODS: We carried out a cross-sectional survey of HNC health professionals (n=260) in the UK and Ireland, assessing participants' knowledge of HPV, their experiences of and attitudes towards discussing HPV with patients, and their willingness to discuss HPV with their patients in the future...

BACKGROUND: Although substantial evidence supports a 20-30% risk reduction of colon cancer, breast cancer, and endometrial cancer by physical activity (PA), the evidence for head and neck cancer (HNC) is limited. Three published studies on the association between PA and HNC have generated inconsistent results. The current study examined the association between recreational PA (RPA) and HNC risk with a more detailed assessment on the intensity, frequency, duration, and total years of RPA...

Follow-up program in head and neck cancer (HNC) is an important issue in patients management. It represents the major dilemma in daily practice clinic. Many guidelines have been published in order to better define the best clinical protocol, but a consensus has not been attained yet. We constructed a follow-up program based on specific primary subsite, to standardize patients surveillance after treatment of HNC.

Formyl cyanide has been detected toward Sgr B2 making this chemical and its potential isomers of astrophysical interest. We calculated the precise energies of the five most stable structural isomers of formyl cyanide and found that formyl isocyanide and 2H-azirin-2-one are less stable than formyl cyanide by 55 and 125 kJ/mol, respectively. We present our ab initio coupled cluster predictions of the spectroscopic parameters relevant to their gas-phase rotational and vibrational spectroscopy. Parameters include ground vibrational state rotational constants, centrifugal distortion parameters, equilibrium electric dipole moments, and nuclear quadrupole coupling constants...

Every year, about 650 thousand new cases of Head and Neck Cancer (HNC) are diagnosed globally. Apart from surgery, radiotherapy (RTH), chemotherapy (CHT) or its combination is used in the treatment of HNC. One of the most frequent complications and, at the same time, limitations of RTH is oral mucositis (OM). Proinflammatory cytokines (including TNF-α) play a key role in the development of OM. Genetic alterations, i.e. single nucleotide polymorphisms (SNPs) within genes encoding for receptors for TNF (ie. TNFRSF1A) may change their function...

Purpose: Head and neck cancers (HNC) often induce profound immunosuppression which contributes to disease progression and interferes with immune-based therapies. Body fluids of HNC patients are enriched in exosomes potentially engaged in negative regulation of anti-tumor immune responses. The presence and content of exosomes derived from plasma of HNC patients are evaluated for the ability to induce immune dysfunction and influence disease activity. <p>Experimental Design: Exosomes were isolated by size-exclusion chromatography from plasma of 38 HNC patients and 14 healthy donors...

Incidence rates of head and neck cancers (HNC) associated with human papillomavirus (HPVa) infection are increasing while non-HPV-associated (non-HPVa) HNC cancer rates are decreasing. As nearly all sexually active individuals will acquire an HPV infection, it is important to understand epidemiologic trends of HNCs associated with this sexually transmitted disease. We analyzed SEER 9 (1973-2012) and 18 data (2000-2012) for HPVa HNCs (oropharynx area; OP) and non-HPVa (oral cavity area; OC). Incidence rates were examined by gender, race, rurality, geographic location, and time...

Oral mucositis (OM) is a common acute side effect during radiotherapy treatments for head and neck cancer (HNC), with a potential impact on patient's compliance to therapy, quality of life (QoL) and clinical outcomes. Its timely and appropriate management is of paramount importance. Several quantitative scoring scales are available to properly assess OM and its influence on patient-reported outcomes (PROs) and QoL. We prospectively assessed OM in a cohort of HNC patients submitted to radiation using the Oral Mucositis Assessment Scale (OMAS), while its impact on PROs and QoL was evaluated employing the Oral Mucositis Weekly Questionnaire-Head and Neck Cancer (OMWQ-HN) and the Functional Assessment of Cancer Therapy-Head and Neck Cancer (FACT-HN)...

PURPOSE: To date, the role of meat and fish intake in head-neck cancer (HNC) etiology is not well understood and prospective evidence is limited. This prompted us to study the association between meat, fish, and HNC subtypes, i.e., oral cavity cancer (OCC), oro- and hypopharyngeal cancer (OHPC), and laryngeal cancer (LC), within the Netherlands Cohort Study (NLCS). METHODS: In 1986, 120,852 participants (aged 55-69 years) completed a baseline 150-item food frequency questionnaire (FFQ), from which daily meat and fish intake were calculated...

Mucosal high-risk (HR) human papillomaviruses (HPV) cause a subset of head and neck cancers (HNC). The HPV-attributable fraction of HNC varies substantially between countries. Although HNC has a very high incidence in the Indian sub-continent, information on the contribution of HPV infection is limited. Here, we evaluated the HPV-attributable fraction in HNC (N=364) collected in a central region of India. HNC from three different anatomical subsites were included, namely oral cavity (n=252), oropharynx (n=53) and hypopharynx/larynx (n=59)...

INTRODUCTION: The incidence of head and neck cancer (HNC) in the UK is rising, with an average of 31 people diagnosed daily. Patients affected by HNC suffer significant short-term and long-term post-treatment morbidity as a result of dysphagia, which affects daily functioning and quality of life (QOL). Pretreatment swallowing exercises may provide additional benefit over standard rehabilitation in managing dysphagia after primary HNC treatments, but uncertainty about their effectiveness persists...
