Previous studies on smokeless tobacco use and head and neck cancer (HNC) have found inconsistent and often imprecise estimates, with limited control for cigarette smoking. Using pooled data from 11 US case-control studies (1981-2006) of oral, pharyngeal, and laryngeal cancers (6,772 cases and 8,375 controls) in the International Head and Neck Cancer Epidemiology (INHANCE) Consortium, we applied hierarchical logistic regression to estimate odds ratios and 95% confidence intervals for ever use, frequency of use, and duration of use of snuff and chewing tobacco separately for never and ever cigarette smokers...

AIMS: The glutathione (GSH), thioredoxin (Trx), and Nrf2 systems represent a major defense against reactive oxygen species (ROS), the cellular imbalance of which in cancer promotes growth and therapeutic resistance. This study investigated whether targeting the GSH, Trx, and Nrf2 antioxidant systems effectively eliminated head and neck cancer (HNC). RESULTS: At high concentrations, auranofin, but not buthionine sulfoximine (BSO) alone, decreased the viability of HNC, whereas even at low concentrations, auranofin plus BSO synergized to kill HNC cells...

INTRODUCTION: The patient's role in toxicity reporting is increasingly acknowledged. There is also a need for developing modern communication methods between the patient and the medical personnel. Furthermore, the increasing number of head and neck cancer (HNC) patients is reflected in the volume of treatment follow-up visits, which remains a challenge for the health care. Electronic patient-reported outcome (ePRO) measures may provide a cost-efficient way to organize follow-up for cancer patients...

We investigated the role of BRCA1, MDM2, and p53 in the pathogenesis of head and neck cancer (HNC) and evaluated their potential utility as blood-based predictive biomarkers of HNC. Immunostaining of tissue biopsies and whole blood lymphocytes (WBL) of 36 HNC patients were evaluated by immunohistochemistry (IHC) and immunocytochemistry (ICC), respectively. The staining intensities of BRCA1 and MDM2 in matched tissue and blood samples were significantly associated with cancer stage. Furthermore, the cellular levels of BRCA1, MDM2, and p53 were evaluated in peripheral blood lymphocytes (PBL) of 134 HNC patients and 126 controls by slot blotting...

Radiation therapy (RT), in particular intensity-modulated radiation therapy (IMRT), is becoming a more important nonsurgical treatment strategy in head and neck cancer (HNC). The further development of IMRT imposes more critical requirements on clinical imaging, and these requirements cannot be fully fulfilled by the existing radiotherapeutic imaging workhorse of X-ray based imaging methods. Magnetic resonance imaging (MRI) has increasingly gained more interests from radiation oncology community and holds great potential for RT applications, mainly due to its non-ionizing radiation nature and superior soft tissue image contrast...

The assessment and evaluation of functioning and quality of life after tumor treatment in head and neck cancer (HNC) are considered as essential aspects of clinical routine and studies. A huge number of instruments are available that have been designed to evaluate functioning and quality of life after HNC treatment. The diversity of these instruments in terms of content, response options and administration hinders the comparability of available studies and the performance of meta-analyses. The objective of this paper is to inform about the development of a screening tool for the standardized assessment and evaluation of functioning based on the International Classification of Functioning, Disability and Health (ICF) Core Set for HNC...

OBJECTIVE: Patients with post-stroke hemiplegia have difficulty with body weight support during walking. However, it is unclear which intra-limb strategy for body weight support tends to predominate, and how the intra-limb strategy is related to gait function. Support moment and individual joint contribution to support moment are the parameters that reflect intra-limb strategy for body weight supporting. The aim of this study was to test whether support moment and individual joint contributions differed between post-stroke subjects with different gait function...

BACKGROUND: Advanced head and neck cancer (HNC) is a complex group of diseases that requires the input and coordination of multiple providers. While there are general guidelines for treatment, there is also considerable variation in how patients are treated, and how long they survive after treatment. It is unclear how the treatment variations relate to treatment costs and survival. METHODS: We identified 3678 Medicare patients with advanced HNC treated in 12 US regions between 2004 and 2009 using the linked database containing Medicare and Surveillance Epidemiology and End Results (SEER) data...
