There is currently no clear distinction between the treatment of HPV-positive and HPV-negative oropharyngeal squamous cell carcinoma (OPSCC). HPV-positive OPSCC has been demonstrated to be more radiosensitive than its HPV-negative counterpart. Despite this, patients with HPV-positive OPSCC continue to receive a full dose of radiation (70 Gy) outside clinical trials. However, this high dose comes with considerable morbidities, including severe mucositis, dysphagia, and xerostomia. We describe the cases of 2 patients with HPV-positive OPSCC who received two cycles of high-dose cisplatin at 100 mg/m(2) on 3 separate days, along with concurrent radiotherapy at 50 Gy in 25 fractions for one and 46 Gy in 23 fractions for the other...

OBJECTIVES: Lymph node ratio (LNR) is an established predictor in different entities of carcinoma, including head and neck malignancies. In oropharyngeal squamous cell carcinoma (OPSCC), lymph node involvement differs between Human Papilloma Virus (HPV)-positive and negative tumours. Herein, we evaluate the impact of HPV association on the concept of LNR. METHODS: 88 surgically treated patients were included in this retrospective chart review. HPV-positive and negative OPSCC were evaluated for prediction of outcome by LNR separately...

Because of the common shared risk factors of smoking and heavy alcohol consumption, literature involving oropharyngeal squamous cell carcinoma (OPSCC) is often combined with oral squamous cell carcinoma. Human papilloma virus is now confirmed to be a major risk factor of OPSCC with its distinct epidemiology and favorable treatment outcome. The impact of adjuvant chemoradiation in the setting of positive surgical margins remains unclear but is likely influenced by tumor biology. This article reviews the tumor biology of OPSCC and summarizes recent findings on outcomes following surgical treatment of OPSCC...

Toll-like receptors (TLRs) have been widely investigated due to their importance in the inflammatory response and possible links to tumor promotion/regression and prognosis. In cancers with an infective etiology, such as human papillomavirus (HPV)-associated Oropharyngeal Squamous Cell Carcinoma (OPSCC), TLR responses may be activated and play a role in tumorigenesis. Our aim was to assess the expression of all TLRs in OPSCC cell lines (both HPV+ and HPV-) by qPCR, Western Blot and flow cytometry and assess their response to TLR ligands lipopolysaccharide (LPS), LPS ultra-pure (LPS-UP) and peptidoglycan (PGN) by analyzing IL-8 and IL-6 production...

There is an incomplete understanding in the pathogenesis of oropharyngeal squamous cell carcinoma (OPSCC) and cancer broadly. It is essential to discover new pathways of normal cell-cycle regulation and oncogenesis. We identified that the loss of inositol polyphosphate-5-phosphatase (INPP5A) may play a role in the development and progression of cutaneous squamous cell carcinoma (SCC).(1) Loss of INPP5A has been previously linked to cancer development and progression.(2) This article is protected by copyright...

The microbiome is fundamentally one of the most unique organs in the human body. Dysbiosis can result in critical inflammatory responses and result in pathogenesis contributing to neoplastic events. We used a pan-pathogen array technology (PathoChip) coupled with next-generation sequencing to establish microbial signatures unique to human oral and oropharyngeal squamous cell carcinomas (OCSCC/OPSCC). Signatures for DNA and RNA viruses including oncogenic viruses, gram positive and negative bacteria, fungi and parasites were detected...

High-risk (HR) human papillomavirus (HPV) is now recognised as the principal cause of the increasing incidence rates of oropharyngeal squamous cell carcinoma (OPSCC) in some parts of the world.The primary risk factor for developing HPV-related OPSCC is oral HPV-infection and the majority of oral HPV-infections are acquired by oral sex. Progression into a OPSCC includes persistent infection with evasion of immune response in the microenvironment, the activation of viral early genes (E6, E7) in basal epithelial cells, the deregulation of cell cycle and the accumulation of chromosomal instability...

The molecular association between human papilloma virus (HPV) and cell cycle-related (CCR) proteins is not fully understood in oropharyngeal squamous cell carcinoma (OPSCC). Herein, we examined the expression levels of CCRs in OPSCCs based on HPV status. In situ hybridization (ISH)- and polymerase chain reaction (PCR)-based assays were used to detect HPV status in 98 OPSCCs, and CCRs were detected by immunostaining. Of 98 tumors, 47 had HPV-positive tumors by either ISH- or PCR-based assays. Concordance analysis between ISH- and PCR-based tests showed a good agreement in OPSCC...

OBJECTIVES: High risk human papillomavirus (HR-HPV) infection leads to a subgroup of oropharyngeal cancer (OPSCC) characterized by improved treatment response. However an universally accepted definition of an HR-HPV-attributable cancer is lacking. METHODS: Detailed, type-specific HPV antibody responses were analyzed by multiplex serology in HR-HPV-attributable OPSCC patients, defined by p16(INK4A) overexpression and HR-HPV DNA detection by PCR amplification and sequencing...

BACKGROUND: Transoral robotic-assisted surgery (TORS) is increasingly utilized in the treatment of oropharyngeal squamous cell carcinoma (OPSCC). Postoperative bleeding is a significant and potentially fatal complication of TORS. Prophylactic ligation of ipsilateral external carotid artery (ECA) branches is a recognized strategy to reduce postoperative bleeding risk. We examined the incidence and sequelae of postoperative oropharyngeal bleeding with and without routine ECA ligation. METHODS: OPSCC patients treated with TORS between 2010 and 2015 with minimum 30days follow up were included...

BACKGROUND: New cases of oropharyngeal squamous cell carcinoma (OPSCC) are routinely tested for HPV. HPV in saliva can be detected with PCR, but its clinical applicability in the context of OPSCC remains unknown. METHODS: Forty-six consecutive patients diagnosed with OPSCC had pre-treatment saliva specimens collected. PCR for HPV on saliva was compared to p16 IHC and HPV DNA in situ hybridisation (ISH) on surgical biopsies. RESULTS: The sensitivity and specificity of saliva testing when compared to the reference test of p16 IHC and HPV DNA ISH were 72...

BACKGROUND: Inclusion of new biomarkers to improve a personalized treatment approach for oropharyngeal squamous cell carcinoma (OPSCC) is urgently needed. Hypomethylation of the Long interspersed nucleotide element-1 (LINE-1) repetitive elements, a widely accepted surrogate of overall genomic DNA methylation content, was found to be associated with a poor prognosis in several cancers. At present, no studies have investigated the influence of LINE-1 methylation levels on OPSCC relapse...

BACKGROUND AND OBJECTIVES: Primary surgical treatment of patients with early T-classification (T1-T2) oropharyngeal squamous cell carcinoma (OPSCC) has increased. We sought to determine how often these patients receive postoperative chemoradiation (CRT). METHODS: Patients with T1-T2 OPSCC in the National Cancer Database who underwent primary surgery were evaluated for receipt of postoperative CRT. Postoperative CRT use was examined among patients with high risk factors (positive margins and/or extracapsular spread [ECS]), intermediate risk factors (negative margins, no ECS, and either pT3-4 and/or N2-N3), and no apparent risk factors...

BACKGROUND: Upfront surgery is a valuable treatment option for oropharyngeal squamous cell carcinoma (OPSCC) and risk stratification is emerging for treatment de-escalation in human papillomavirus (HPV)-related OPSCC. Available prognostic models are either based on selected, mainly non-surgically treated cohorts. Therefore, we investigated unselected OPSCC treated with predominantly upfront surgery. METHODS: All patients diagnosed with OPSCC and treated with curative intent between 2000 and 2009 (n=359) were included...

BACKGROUND: Transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) has been associated with improved long-term dysphagia symptomatology compared with chemoradiation. Dysphagia in the perioperative period has been inadequately characterized. The objective of this study was to characterize short-term swallowing outcomes after TORS for OPSCC. METHODS: Patients undergoing TORS for OPSCC were enrolled prospectively. The Eating Assessment Tool 10 (EAT-10) was used as a measure of swallowing dysfunction (score >2) and was administered on postoperative day (POD) 1, 7, and 30...
