In this article, we reviewed the association between alcohol drinking and head and neck cancer (HNC) and its subsites, using the available literature. Alcohol drinking is an established risk factor for HNC, and this association may be stronger among cancers of the oropharynx and hypopharynx than the oral cavity or larynx. In addition, higher alcohol consumption over a shorter period was more harmful than fewer alcohol consumption over a longer period, and the most frequently consumed alcoholic beverages in a population is likely to be associated with the highest risk of HNC in that population...

OBJECTIVES: Mucoepidermoid carcinoma (MEC) is an uncommon malignancy that most commonly occurs in the parotid gland followed by the minor salivary glands of the upper aerodigestive tract, most notably in the oral cavity (OC) and oropharynx (OP). Because of its rarity, few studies have been performed that are specific to MEC within the OC and OP. The objective of this study is to describe the tumor characteristics and prognostic features for MEC of the OC and OP. MATERIALS AND METHODS: The National Cancer Database (NCDB) was used for this study...

REVIEW
Sigrun Smola, Connie Trimble, Peter L Stern
It is now recognized that the immune system can be a key component of restraint and control during the neoplastic process. Human papillomavirus (HPV)-associated cancers of the anogenital tract and oropharynx represent a significant clinical problem but there is a clear opportunity for immune targeting of the viral oncogene expression that drives cancer development. However, high-risk HPV infection of the target epithelium and the expression of the E6/E7 oncogenes can lead to early compromise of the innate immune system (loss of antigen-presenting cells) facilitating viral persistence and increased risk of cancer...

BACKGROUND: Head and neck cancers include malignancies of the mouth, larynx and oropharynx. Tobacco use and alcohol consumption are associated with increased risks of developing and dying from head and neck cancer. The aim of this review is to examine the effectiveness of smoking and alcohol cessation interventions on disease-related outcomes, quality of life and behavioural change in adults with head and neck cancer and oral dysplasia. METHODS: The Cochrane library, CINAHL, Embase, MEDLINE, PsycINFO and Web of Science databases will be searched for randomised controlled trials investigating the effects of smoking or alcohol interventions on patients with either head and neck cancer or oral dysplasia...

BACKGROUND: Squamous cell carcinoma of the head and neck (HNSCC) represents an array of disease processes with a generally unfavorable prognosis. Inflammation plays an important role in tumor development and response to therapy. We performed a retrospective analysis of HNSCC patients to explore the relationship of the lymphocyte and neutrophil counts, the neutrophil-to-lymphocyte ratio (NLR) overall survival (OS), cancer-specific survival (CSS), local control (LC) and distant control (DC)...

Very little data exist on the incidence and burden of cancer in the individual Caribbean countries. Some data are available for larger areas, reported under a bigger geographical region; Latin America and the Caribbean, but many of the individual countries are not included. One of the main reasons is a lack of official cancer registries. Data are usually collected from hospital records or private physician records, and since it is not in an official registry, these data are not always accessible for inclusion in databases such as SEER and GLOBOCAN...

Enteral feeding is often required for nutrition support in head and neck cancer patients when oral intake is inadequate. When to initiate the insertion of a feeding tube continues to be a debated issue in our institution. We investigated the use of reactive feeding tubes (RFTs) in patients with advanced stage oropharynx cancer (OPC). Data were retrospectively collected on 131 patients who had radiotherapy (RT) ± chemotherapy from 2005 to 2015. Predictors for RFT insertion were investigated. Weight loss during RT was compared between those with RFT versus prophylactic tubes (PFTs) versus no tube, and survival outcomes evaluated...

INTRODUCTION: The prevalence and activity of regulatory T cells in patients with cancer correlates with poor prognosis. These cells are characterized by their expression of Forkhead box protein-3 (Foxp3). Squamous cell carcinoma is the most prevalent type of cancer in the head and neck region with overall poor survival rates, also due to early spread of metastatic cells. MATERIAL AND METHODS: Primary tumor specimens as well as lymph node specimens harvested during neck dissection of 65 patients with a diagnosis of HNSCC were subjected to immunohistochemical and H-score analysis of Foxp3 expression...

PURPOSE: Low-dose fractionated radiation therapy (LDFRT) induces effective cell killing through hyperradiation sensitivity and potentiates effects of chemotherapy. We report our second investigation of LDFRT as a potentiator of the chemotherapeutic effect of induction carboplatin and paclitaxel in locally advanced squamous cell cancer of the head and neck (SCCHN). EXPERIMENTAL DESIGN: Two cycles of induction therapy were given every 21 days: paclitaxel (75 mg/m(2)) on days 1, 8, and 15; carboplatin (area under the curve 6) day 1; and LDFRT 50 cGy fractions (2 each on days 1, 2, 8, and 15)...

PURPOSE: To determine dosimetric parameters associated with osteoradionecrosis (ORN) in oropharyngeal cancer (OPC) patients in the IMRT era. MATERIAL AND METHODS: Subsequent to institutional review board approval, we identified ORN in OPC patients treated with IMRT from 2002 to 2013. 1:2 case-control matching was implemented. Mandibular dose-volume histograms (DVH) were extracted. Dosimetric parameters were compared using non-parametric stats. Recursive partitioning analysis (RPA) was done to identify DVH correlates of ORN...

INTRODUCTION: The aim of this study was to evaluate the expression of PD-L1 in oropharyngeal squamous cell carcinoma. Its relation with clinicopathological variables such as amount and type of tumor infiltrating lymphocytes, HPV status and survival was also determined. RESULTS: Positive PD-L1 status for the SP142 clone related with improved overall survival in oropharyngeal squamous cell carcinoma. Tumors heavily infiltrated by tumor infiltrating lymphocytes were also linked with better outcome, and this as well for the total number of tumor infiltrating lymphocytes as for the CD3+ and CD8+ T cell count...

Due to lower female incidence, estimates of exogenous and endogenous hormonal factors in head and neck cancers (HNCs, comprising cancers of the oral cavity, oropharynx, hypopharynx, and larynx) among women have been inconsistent and unable to account for key HNC risk factors. We pooled data from 11 studies from Europe, North America, and Japan. Analysis included 1572 HNC female cases and 4343 controls. Pooled odds ratios (ORs) estimates and their 95% confidence intervals (CIs) were calculated using multivariate logistic regression models adjusting for tobacco smoking and alcohol drinking...

REVIEW
Eduard Monsó
The introduction of culture-independent techniques for the microbiological analysis of respiratory samples has confirmed that the respiratory system hosts a large number of microorganisms, which include a wide range of bacteria. The regular exposure to tobacco smoke changes the microbiome in healthy smokers, first in the oropharynx, increasing the presence of a restricted number of genera which attain high relative abundance, a pattern that may be considered as dysbiosis. In chronic obstructive pulmonary disease (COPD), microbiome analyses of sputum samples have demonstrated an important decline in bacterial diversity, with a change to a restricted flora with an overrepresentation of the Proteobacteria phylum, which include most of the bacteria commonly considered as potentially pathogenic microorganisms, paralleled by a decline in the relative abundance of microorganisms part of the Firmicutes phylum...

BACKGROUND: Concurrent chemoradiation with 3 weekly cisplatin (100 mg/m(2)) is the standard of care for locally advanced head and neck cancer. However, this regimen has been shown to be associated with lesser compliance and higher toxicities. Hence, there is a need to explore alternative concurrent cisplatin regimens. OBJECTIVES: The objective of this study was to compare the efficacy and toxicities of 3 weekly cisplatin (100 mg/m(2)) with weekly cisplatin (40 mg/m(2)) concurrently with radiation in patients with locally advanced head and neck cancer...

BACKGROUND AND STUDY AIMS:  Performing a percutaneous endoscopic gastrostomy (PEG) in head and neck cancer (HNC) patients can be challenging because of the presence of trismus, pharyngeal obstruction by tumor, and pharyngoesophageal strictures or fistula. Pharyngocutaneous fistula (PCF) is a major postoperative concern in patients submitted to total laryngectomy (TL). In the medical literature to date, the cervical fistula has been used as an access to PEG in only four reports. The aim of this study was to evaluate the safety of cervical fistula for insertion of a PEG tube...
