One of the most common head and neck cancers is laryngeal squamous cell carcinoma (LSCC). LSCC exhibits high mortality rates and has a poor prognosis. The molecular mechanisms leading to the development and progression of LSCC are not entirely clear despite genetic and therapeutic advances and increased survival rates. In this study, a total of 116 differentially expressed genes (DEGs), including 11 upregulated genes and 105 downregulated genes, were screened from LSCC samples and compared with adjacent noncancerous...

Calprotectin (S100A8/A9), a heterodimeric complex of calcium-binding proteins S100A8 and S100A9, is encoded by genes mapping to the chromosomal locus 1q21.3 of the epidermal differentiation complex. Whereas extracellular calprotectin shows proinflammatory and antimicrobial properties by signaling through RAGE and TLR4, intracytoplasmic S100A8/A9 appears to be important for cellular development, maintenance, and survival. S100A8/A9 is constitutively expressed in myeloid cells and the stratified mucosal epithelia lining the oropharyngeal and genitourinary mucosae...

Perineural invasion (PNI) is a mechanism of tumor dissemination that can provide a challenge to tumor eradication and that is correlated with poor survival. Squamous cell carcinoma, the most common type of head and neck cancer, has a high prevalence of PNI. This review provides an overview of clinical studies on the outcomes and factors associated with PNI in head and neck cancer and on findings on cancer-nerve crosstalk.

BACKGROUND: The perioperative use of immunomodulatory nutrition formulas in patients with head and neck cancer reduces the number of postoperative infections and the length of hospital stay. OBJECTIVE: An exploratory, randomized, controlled, blind, clinical trial was designed to examine the effect of the preoperative consumption of a new, immunomodulatory, oral nutrition formula in patients with head and neck cancer. METHODS: Thirty-eight patients were randomized to receive either 400 mL/d of either the new immunomodulatory formula (IF) or that commonly used in clinical practice (CF) over 10 days prior to surgery...

Patients with Sjögren's syndrome, an autoimmune disease affecting the exocrine glands, develop salivary gland inflammation and have reduced saliva production. Similarly, saliva production is severely compromised in patients receiving radiation treatment for head and neck cancers. Rodent models, developed to mimic these clinical conditions, facilitate an understanding of the disease pathogenesis and allow for the development of new therapeutic strategies. Therefore, the ability to accurately, reproducibly, and repeatedly measure salivary gland function in animal models is critical...

REVIEW
Alessandro Guidi, Carla Codecà, Daris Ferrari
Head and neck cancer (HNC) is a fatal malignancy with an overall long-term survival of about 50% for all stages. The diagnosis is not rarely delayed, and the majority of patients present with loco-regionally advanced disease. The rate of second primary tumors after a diagnosis of HNC is about 3-7% per year, the highest rate among solid tumors. Currently, a single-modality or a combination of surgery, radiotherapy and chemotherapy (CHT), is the standard treatment for stage III-IV HNC. For the recurrent/metastatic setting, in the last 40 years great efforts have been made in order to develop a more effective CHT regimen, from the use of methotrexate alone, to the combination of cisplatin (CDDP) and 5-fluorouracile (5FU) or paclitaxel...

Evolution of targeted therapy has changed the spectrum of treatment in oncology since the past two decades as lots of newer agents are being added to the pharmacologic armamentarium of cancer therapy. Epidermal growth factor receptor inhibitors form one such advancing field with many newer agents being investigated and they are used in wide variety of malignancies such as head and neck cancer, lung cancer, and even gastrointestinal malignancies such as pancreatic cancer. Various troublesome side effects of these agents include diarrhea, severe fatigability, severe skin rashes, and deranged liver function tests which may require treatment interruption or dose reduction resulting in decreased response to treatment...

Background: Conceptual models developed through qualitative research are based on the unique experiences of suffering and individuals' adoptions of each participant. A wide array of problems are faced by head-and-neck cancer (HNC) patients due to disease pathology and treatment modalities which are sufficient to influence the quality of life (QOL). Men possess greater self-acceptance and are better equipped with intrapersonal strength to cope with stress and adequacy compared to women...

Human papillomavirus (HPV) type 16 is implicated in approximately 75% of head and neck squamous cell carcinomas (HNSCC) that arise in the oropharynx, where viral expression of the E6 and E7 oncoproteins promote cellular transformation, tumor growth, and maintenance. An important oncogenic signaling pathway activated by E6 and E7 is the phosphatidylinositol 3-kinase (PI3K) pathway, a key driver of carcinogenesis. The PI3K pathway is also activated by mutation or amplification of PIK3CA in over half of HPV(+) HNSCC...

BACKGROUND: Saliva is fundamental to our oral health and our well-being. Many factors can impair saliva secretion, such as adverse effects of prescribed medication, auto-immune diseases (for example Sjögren's syndrome) and radiotherapy for head and neck cancers. Several studies have suggested a positive effect of acupuncture on oral dryness. METHODS: Pubmed and Web of Science were electronically searched. Reference lists of the included studies and relevant reviews were manually searched...

Dynamic myraidpro contrast-enhanced magnetic resonance imaging (DCE-MRI) has been correlated with prognosis in head and neck squamous cell carcinoma as well as with changes in normal tissues. These studies implement different software, either commercial or in-house, and different scan protocols. Thus, the generalizability of the results is not confirmed. To assist in the standardization of quantitative metrics to confirm the generalizability of these previous studies, this data descriptor delineates in detail the DCE-MRI digital imaging and communications in medicine (DICOM) files with DICOM radiation therapy (RT) structure sets and digital reference objects (DROs), as well as, relevant clinical data that encompass a data set that can be used by all software for comparing quantitative metrics...

Roughly 436,000 survivors are living with a history of head and neck cancer (HNC), accounting for approximately 3% of all cancer survivors in the United States [1, 2]. With advances in treatment, long-term survival is increasingly common in HNC populations. Despite increasing awareness of survivorship issues, many challenges remain. These include lack of knowledge on late and long-term effects of treatment, and poor integration of survivorship care guidelines into oncology practice. Survivorship care plans (SCPs) are increasingly important for HNC survivors to improve quality of long-term survival...

Patients with head and neck cancers (HNC) face multiple psychosocial and physical challenges that require multidisciplinary attention and care throughout their disease process. The psychoemotional symptoms may be triggered by cosmetic disfigurement and/or functional deficits related to the cancer itself or cancer-directed treatments. These physical and emotional symptoms can be demoralizing and require acute and long-term professional assistance throughout a patient's lifespan. HNC remains one of the most challenging cancers to treat due to disfigurement, emotional suffering, social isolation, and loss of self-esteem...

In this chapter, we examine the demographics and risk factors in the population diagnosed with head and neck cancer (HNC), what challenges these patients face post-treatment and what the role of psychosocial support through clinical social work is in managing these stressors. While many forms of head and neck cancer found in the early stages have a high cure rate, the side effects of treatment for these cancers have major life-altering effects. Previously, the majority of those diagnosed with head and neck cancers were those who used excessive alcohol and tobacco, but the numbers are changing to include the human papillomavirus (HPV) as a major risk factor...

Occupational therapy is a health profession concerned with promoting health and well-being through occupation. A diagnosis of head and neck cancer (HNC) often invokes fear and anxiety because of the potential negative impact of the diagnosis and/or treatment on lifestyle and well-being. Occupational therapists perform a unique and important role in addressing quality of life concerns for HNC patients through applied expertise in lifestyle management, facilitating the use of positive coping strategies and daily routine management...

Treatment sequelae such as trismus, shoulder dysfunction syndrome resulting from spinal accessory nerve palsy, and radiotherapy-induced neck fibrosis are often overlooked when in the management of head and neck cancer patients. This chapter examines these underappreciated issues and their corresponding physical therapy intervention based on current evidence. Head and neck cancer survivors must contend with these disabilities for years after treatment has been concluded. A few quit their jobs which puts a tremendous burden on them and their families with a diminished quality of life...

Head and neck cancer (HNC) patients often face multiple nutritional challenges before, during, and after treatment due to the close proximity of the cancer to organs that are vital for normal eating function. Common treatment-related side effects, such as dysphagia, odynophagia, dysgeusia, xerostomia, thick saliva, mucositis, nausea, and vomiting, all further impair the patient's ability to maintain adequate oral intake. Malnutrition and unintentional weight loss in HNC patients during and after treatment are associated with poorer treatment outcomes, increased morbidity and mortality, and poor quality of life, even in overweight and obese patients whose Body Mass Index (BMI) is not suggestive of malnutrition...
