PURPOSE: Treatment for head and neck cancer (HNC) results in long-term toxicities and increased physical and psychosocial survivor burden. There are a limited number of treatments for these late effects. Yoga postures, breath work, relaxation, and meditation, may improve these late effects. The purpose of this study was to examine the feasibility of a tailored yoga program in HNC survivors and obtain preliminary efficacy data. METHODS: This was a randomized wait-list control study of yoga-naive HNC survivors who were >3 months post-cancer treatment...

We have derived a hypernetted-chain-like (HNC-like) approximate closure of the Ornstein-Zernike equation for multibody dissipative particle dynamics (MDPD) system in which the classic closures are not directly practicable. We first point out that the Percus's method is applicable to MDPD system in which particles interact with a density-dependent potential. And then an HNC-like closure is derived using Percus's idea and the saddle-point approximation of particle free energy. This HNC-like closure is compared with results of previous researchers, and in many cases, it demonstrates better agreement with computer simulation results...

Telomeres are transcribed into noncoding telomeric repeat-containing RNAs (TERRA), which are essential for telomere maintenance. Deregulation of TERRA transcription impairs telomere metabolism and a role in tumorigenesis has been proposed. Head and neck cancer (HNC) is one of the most frequent cancers worldwide, with head and neck squamous cell carcinoma (HNSCC) being the predominant type. Since HNSCC patients are characterized by altered telomere maintenance, a dysfunction in telomere transcription can be hypothesized...

Distant metastasis (DM) from head and neck cancers (HNC) portends a poor patient prognosis. Despite its important biological role, little is known about the cells which seed these DM. Circulating tumour cells (CTCs) represent a transient cancer cell population, which circulate in HNC patients' peripheral blood and seed at distant sites. Capture and analysis of CTCs offers insights into tumour metastasis and can facilitate treatment strategies. Whilst the data on singular CTCs have shown clinical significance, the role of CTC clusters in metastasis remains limited...

June R Greaves
The National Institutes of Health National Cancer Institute estimates that over 13,000 new cases of head and neck cancer (HNC) will be diagnosed in 2017. Patients with HNC often require enteral nutrition (EN) via gastrostomy tube to provide nutrition support and hydration because of tumor obstruction of the oropharynx and/or cumulative effects of chemoradiation therapy. The percutaneous endoscopic gastrostomy (PEG) tube has become the preferred technique for EN access because placement is considered a minimally invasive procedure...

The ability of Be3 as a hydrogen bond acceptor has been explored by studying the potential complexes between this molecule and a set of hydrogen bond donors (HF, HCl, HNC, HCN, H2O and HCCH). The electronic structure calculations for these complexes were carried out at the MP2 and CCSD(T) computational levels, together with an extensive NBO, ELF, AIM and electrostatic potential characterization of the isolated Be3 system. In all the complexes, the Be-Be σ bond acts as electron donor, with binding energies between 19 and 6 kJ·mol-1...

Objectives: Head and neck cancer (HNC) patients often require percutaneous gastrostomy (PEG) tube placement due to malnutrition and dysphagia. While beneficial, PEG tube placement can cause a rare but reportable complication of metastasis of the original tumor to the gastrostomy exit site. The objectives of this case series were to present HNC patients at a single institution that developed PEG tube metastases, their subsequent treatment, and review of the literature for similar cases...

AKT (also known as protein kinase B, PKB) plays an important role in cell survival or tumor progression. For these reasons, AKT is an emerging target for cancer therapeutics. Previously our studies showed that mitochondrial E3 ubiquitin protein ligase 1 (MUL1, also known as MULAN/GIDE/MAPL) is suppressed in head and neck cancer (HNC) and acts as negative regulator against AKT. However, the MUL1 regulatory mechanisms remain largely unknown. Here we report that cisplatin (CDDP) induces thyroid cancer cell death through MUL1-AKT axis...

Constitutively activated signal transducer and activator of transcription 3 (STAT3) factor is an important therapeutic target in head and neck cancer (HNC). Despite early promising results, a reliable systemic delivery system for STAT3- targeted oligonucleotide (ODN) drugs is still needed for future clinical translation of anti-STAT3 therapies. We engineered and tested a novel ODN duplex/gold nanoparticle (AuNP)-based system carrying a therapeutic STAT3 decoy (STAT3d) payload. This strategy is two-pronged because of the additive STAT3 antagonism and radiosensitizing properties of AuNP...

Treatment of head and neck cancer (HNC) is accompanied by a high rate of morbidity, and complications can have a lifelong, profound impact on both patients and caregivers. Radiation-related injury to the hard and soft tissue of the head and neck can significantly decrease patients' quality of life. The purpose of this study is to provide patent-specific guidelines for managing the oral health and related side effects of HNC patients treated with radiation therapy. Based on reviewed articles retrieved on the PubMed database, guidelines for management of the oral health of this patient population were organized into three separate categories: cancer, patient, and dentition...

Head and neck cancer (HNC) remains the sixth most common malignancy worldwide and survival upon recurrence and/or metastasis remains poor. HNSCC has traditionally been associated with alcohol and nicotine use, but more recently the Human Papilloma Virus (HPV) has emerged as a favorable prognostic risk factor for oropharyngeal HNSCC. However, further stratification with additional biomarkers to predict patient outcome continues to be essential. One candidate biomarker is the DEK oncogenic protein, which was previously detected in the urine of patients with bladder cancer and is known to be secreted by immune cells such as macrophages...

Bone marrow mesenchymal stem cells (BMMSCs) have been shown to be recruited to tumor microenvironment and exert a tumor-promoting effect in a variety of cancers. However, the molecular mechanisms related to the tumor-promoting effect of BMMSCs on head and neck cancer (HNC) were not clear. In this study, we investigated Periostin (POSTN) and its roles in tumor-promoting effect of BMMSCs on HNC. In vitro analysis of HNC cells cultured in BMMSCs conditioned media (MSC-CM) showed that MSC-CM significantly promoted the cancer progression by enhancing cell proliferation, migration, epithelial-mesenchymal transformation (EMT), altering expression of cell cycle regulatory proteins and inhibition of apoptosis...

BACKGROUND: Endoscopic gastrostomy (PEG) fed patients, including those with neurologic disorders (ND) or head and neck cancer (HNC) present high malnutrition risk and speech difficulties. Teams taking care of these patients need to rely on anthropometric data. Skinfold thickness (TSF) is used to assess nutritional status, but the use of heavy, large and expensive metal calipers may become a limitation. This study aimed to compare and correlate TSF measurements using a metal caliper and a plastic caliper in PEG fed patients...

PURPOSE: Concomitant cetuximab and radiation therapy (RT) can induce severe radiodermatitis in patients with head and neck cancer (HNC). OTD70DERM, a regenerating agent (RGTA), is a structural and functional analogue of glycosaminoglycans. Preclinical studies have shown that topical RGTA can markedly reduce radiation-induced mucosal and cutaneous toxicities without tumor protection. The present study aimed to evaluate the effect of topical RGTA on radiodermatitis in patients with HNC undergoing RT and cetuximab, for whom RT-induced skin reactions are frequent and/or severe...

HSPA5/GRP78/BiP plays an important role in cell survival or tumor progression. For these reasons, HSPA5 is an emerging therapeutic target in cancer development. Here we report that HSPA5 contributes to head and neck cancer (HNC) survival via maintenance of lysosomal activity; however, a nonthermal plasma (NTP, considered as a next-generation cancer therapy)-treated solution (NTS) inhibits HNC progression through HSPA5-dependent alteration of lysosomal activity. HSPA5 prevents NTS-induced lysosome inhibition through lysosomal-related proteins or regulation of gene expression...
