BACKGROUND: A number of studies had reported the association between tumor necrosis factor-alpha (TNF-α) gene polymorphisms and head and neck cancer (HNC) risk. However, the results remained controversial. Therefore, we performed a meta-analysis to derive a more precise evaluation of the association between TNF-α-308G/A polymorphism and overall HNC risk and evaluated influence of cancer types and ethnicities. METHODS: A systematic literature search was performed using Pubmed, Embase, Cochrane Library, and Web of science...

In patients undergoing irradiation therapy, injury to non-tumor tissues can result in debilitating, and sometimes permanent, side effects. We have defined Protein Kinase C-delta (PKCδ) as a regulator of DNA damage induced apoptosis and have shown that phosphorylation of PKCδ by c-Abl and c-Src activates its pro-apoptotic function.  Here we have explored the use of tyrosine kinase inhibitors (TKIs) of c-Src and c-Abl to block activation of PKCδ for radioprotection of the salivary gland.  Dasatinib, imatinib, and bosutinib all suppressed tyrosine phosphorylation of PKCδ and inhibited IR-induced apoptosis in vitro  To determine if TKIs can provide radioprotection of salivary gland function in vivo, mice were treated with TKIs and a single or fractionated doses of irradiation...

PURPOSE: This exploratory and descriptive study contributes to the growing knowledge about the return-to-work (RTW) experience of head and neck cancer (HNC) survivors. Viewing RTW as a process, participants were asked to consider the work-related experience with HNC at different phases: (1) at diagnosis/pre-treatment, (2) working during treatment (if the respondent did not take a work disability leave), and (3) post-treatment/RTW (if the respondent took a work disability leave). METHODS: Data were gathered in nine individual semi-structured in-depth interviews with patients receiving treatment at a quaternary cancer center's HNC clinic in Ontario, Canada...

INTRODUCTION: Patients with head and neck cancer (HNC) submitted to radiotherapy alone or combined chemoradiotherapy present a high prevalence of malnutrition at baseline. Prophylactic use of gastrostomy has been suggested for these patients for delivering enteral nutrition. On the other hand, other authors have failed to demonstrate the effectiveness of this measure over nasogastric tube feeding. MATERIAL AND METHODS: We studied 40 patients with HNC with moderate or severe malnutrition who were offered either prophylactic percutaneous gastrostomy before starting oncologic treatment or close follow-up with nutritional counseling with the placement of a nasogastric tube when necessary...

PURPOSE: Dysphagia is one of the most important treatment-related side effects in head and neck cancer (HNC), as it can lead to severe life-threating complications such as aspiration pneumonia and malnutrition. Intensity-modulated radiotherapy (IMRT) could reduce swallowing dysfunction by producing a concave dose distribution and reducing doses to the swallowing-related organs at risk (SWOARs). The aim of this study was to review the current literature in order to compare swallowing outcomes between IMRT and three-dimensional conformal radiotherapy (3DCRT)...

Patients with head and neck cancers (HNC) can experience significant distress from presentation of symptoms to surveillance/survivorship and end-of-life. It is of value to all members of the HNC team to practice patient-centered care in assessment and interventions with patients and their support systems to achieve the best possible outcome given patient health status. Early assessment and referral to ancillary support provide a strong foundation across the illness trajectory. Specific attention should be given to the psychosocial implications of changes in physiologic functioning...

PURPOSE: There is a lack of effective diagnostic tools for early assessment of radiotherapy (RT) outcome in patients with head and neck cancer (HNC). The timely diagnosis of treatment failure may facilitate use of salvage procedures to prevent disease progression. We assessed squamous cell carcinoma antigen and CYFRA 21-1 as early markers of radiotherapy failure in patients with HNC. METHODS: Between January 2009 and February 2012, 185 patients (median age 59 years) with squamous cell carcinoma were treated with curative intent with RT alone or combined with chemotherapy (ChT)...

BACKGROUND: Programmed cell death ligand 1 (PD-L1) expression was reported to be correlated with poor prognosis in various cancers. However, the relationship between PD-L1 expression and the survival of patients with head and neck cancer (HNC) remains inconclusive. In the present study, we aimed to clarify the prognostic value of PD-L1 in HNC patients using meta-analysis techniques. METHODS: A comprehensive database searching was conducted in the PubMed, EMBASE, Web of Science and Cochrane Library from inception to August 2016...

Older adults with head and neck squamous cell carcinoma (HNSCC) pose unique treatment and supportive care challenges to oncologists and other cancer care providers. The majority of patients with HNSCC present with locoregionally advanced disease, for which combined-modality treatment integrating chemotherapy and radiation therapy is often necessary to maximize tumor control. However, applying these approaches to an older population with concomitant comorbidities and a higher risk of functional impairments remains challenging and is exacerbated by the paucity of studies involving older adults...

This report presents the fabrication and pressure-driven processing of heterostructural nanocrystal superlattices (HNC-SLs) self-assembled from quantum-dot-Au (QD-Au) satellite-type HNCs. In situ small/wide-angle X-ray scattering and electron microscopic measurements showed that the HNC-SLs underwent structural transformation at both atomic- and mesoscales during the pressure processing. Upon deviatoric stress-driven orientational migration, the intraparticle coalescence of Au satellites at QD surfaces transforms individual HNCs into heterodimers, whereas the interparticle fusion drives assembled HNCs into ordered heterorod arrays...

Reactivation of p53 and induction of tumor cell apoptosis (RITA) is a small molecule that blocks p53-MDM2 interaction, thereby reactivating p53 in tumors. RITA can induce exclusive apoptosis in cancer cells independently of the p53 pathway; however, the resistance of cancer cells remains a major drawback. Here, we found a novel resistance mechanism of RITA treatment and an effective combined treatment to overcome RITA resistance in head and neck cancer (HNC) cells. The effects of RITA and 3-methyladenine (3-MA) were tested in different HNC cell lines, including cisplatin-resistant and acquired RITA-resistant HNC cells...

BACKGROUND: Adherence to swallowing rehabilitation exercises is important to develop and maintain functional improvement, yet more than half of head and neck cancer (HNC) patients report having difficulty adhering to prescribed regimens. Health apps with game elements have been used in other health domains to motivate and engage patients. Understanding the factors that impact adherence may allow for more effective gamified solutions. OBJECTIVE: The aim of our study was to (1) identify self-reported factors that influence adherence to conventional home therapy without a mobile device in HNC patients and (2) identify appealing biofeedback designs that could be used in a health app...
