BACKGROUND: There are few published studies to guide the treatment of carcinoma metastatic to the neck from an unknown primary (CUP). In this regard, the objective of the current study was to share the authors' current experience treating patients with CUP using intensity-modulated radiation therapy (IMRT), which principally targeted both sides of the neck, the nasopharynx, and the oropharynx. METHODS: This was a retrospective study in which an institutional database search was conducted to identify patients with CUP who received IMRT...

REVIEW
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...

BACKGROUND: Time to treatment initiation (TTI) is increasing and is associated with worsening survival. In the current study, the authors sought to identify a mechanism for this relationship by assessing the effect of TTI on clinical-to-pathologic upstaging in patients with head and neck squamous cell carcinoma (HNSCC). METHODS: Using the National Cancer Data Base, the authors analyzed patients receiving definitive surgery for SCC of the oral cavity, oropharynx, larynx, and hypopharynx from 2005 through 2014...

Background: The majority of patients diagnosed with oropharyngeal squamous cell cancer (OPSCC) are due to HPV infection. At present, there are no reliable tests for screening HPV in patients with OPSCC. The objective of this study was to assess the Cobas® HPV Test on oral rinse specimens as an early, non-invasive tool for HPV-related OPSCC. Methods: Oral rinse specimens were collected from 187 patients (45 with OPSCC, 61 with oral cavity SCC (OCSCC) and 81 control patients who had benign or malignant thyroid nodules) treated at MSKCC...

REVIEW
Mikko T Nieminen, Mikko Salaspuro
The resident microbiome plays a key role in exposure of the upper gastrointestinal (GI) tract mucosa to acetaldehyde (ACH), a carcinogenic metabolite of ethanol. Poor oral health is a significant risk factor for oral and esophageal carcinogenesis and is characterized by a dysbiotic microbiome. Dysbiosis leads to increased growth of opportunistic pathogens (such as Candida yeasts) and may cause an up to 100% increase in the local ACH production, which is further modified by organ-specific expression and gene polymorphisms of ethanol-metabolizing and ACH-metabolizing enzymes...

Aru Panwar, Erik Interval, William M Lydiatt Emba
The staging of oropharyngeal squamous cell carcinoma has undergone key changes in the eighth edition of the American Joint Committee on Cancer Staging Manual, set to take effect January 1, 2018. The most significant change relates to the development of a novel staging system for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinomas, distinct from that for non-HPV-associated squamous cell carcinomas of the oropharynx. We describe the revised staging parameters and the rationale in support of the changes...

BACKGROUND: The growing epidemic of human papillomavirus-positive (HPV+) oropharyngeal cancer and the favorable prognosis of this disease etiology have led to a call for deintensified treatment for some patients with HPV+ cancers. One of the proposed methods of treatment deintensification is the avoidance of chemotherapy concurrent with definitive/adjuvant radiotherapy. To the authors' knowledge, the safety of this form of treatment de-escalation is unknown and the current literature in this area is sparse...

Mitra Mehrad, William D Dupont, W Dale Plummer, James S Lewis
The favorable features of high-risk human papillomavirus (HPV) in the head and neck are limited to those harboring transcriptionally-active HPV, which occur predominantly in the oropharynx (OP). Factors rendering the OP susceptible to HPV oncogenesis are largely unexplored. The role of cytokeratin 7 (CK7) in predisposition to HPV and cancer in the cervix has been evaluated. However, its significance in the H&N is unknown. CK7 immunohistochemistry was performed on a tissue microarray cohort of OP and non-oropharyngeal (NOP) squamous cell carcinomas (SCC) with known clinical follow-up and HPV E6/7 mRNA status...

REVIEW
Mikko Salaspuro
Ethanol is neither genotoxic nor mutagenic. Its first metabolite acetaldehyde, however, is a powerful local carcinogen. Point mutation in ALDH2 gene proves the causal relationship between acetaldehyde and upper digestive tract cancer in humans. Salivary acetaldehyde concentration and exposure time are the two major and quantifiable factors regulating the degree of local acetaldehyde exposure in the ideal target organ, oropharynx. Instant microbial acetaldehyde formation from alcohol represents >70% of total ethanol associated acetaldehyde exposure in the mouth...

REVIEW
Pierre Blanchard, Gary Brandon Gunn, Alexander Lin, Robert L Foote, Nancy Y Lee, Steven J Frank
Because of its sharp lateral penumbra and steep distal fall-off, proton therapy offers dosimetric advantages over photon therapy. In head and neck cancer, proton therapy has been used for decades in the treatment of skull-base tumors. In recent years the use of proton therapy has been extended to numerous other disease sites, including nasopharynx, oropharynx, nasal cavity and paranasal sinuses, periorbital tumors, skin, and salivary gland, or to reirradiation. The aim of this review is to present the physical properties and dosimetric benefit of proton therapy over advanced photon therapy; to summarize the clinical benefit described for each disease site; and to discuss issues of patient selection and cost-effectiveness...

This article is a continuation of the "Do You Know Your Guidelines" series, initiated by the Education committee of the American Head and Neck Society. Treatment guidelines for advanced head and neck squamous cell carcinoma are reviewed here, including the critical roles of radiotherapy, chemotherapy, and the recent application of immunotherapy agents. We will be limiting this discussion to include cancers of the oral cavity, oropharynx, hypopharynx, and larynx. It should be noted that much of the article pertains to human papillomavirus (HPV)-negative oropharyngeal cancer where applicable, as HPV-positive oropharyngeal squamous cell carcinoma carries a different natural history, different prognosis, and now different staging criteria...
