PURPOSE: Patients with human papillomavirus (HPV)-related head and neck cancer (HNC) have a better prognosis relative to other types of HNC, making survivorship an emerging and critical issue. Exercise is a core component of survivorship care, but little is known about how many survivors of HPV-related HNC can safely be advised to start exercising on their own, as opposed to needing further evaluation or supervised exercise. METHODS: We utilized guidelines to identify health issues that would indicate value of further evaluation prior to being safely prescribed unsupervised exercise...

BACKGROUND: Human papillomavirus (HPV)-positive oropharyngeal cancer is associated with favorable outcomes, prompting investigations into treatment deintensification. The purpose of this study was for us to present the predictors of distant metastases in patients with HPV-positive oropharyngeal cancer treated with cisplatin-based chemoradiotherapy (CRT) or cetuximab-based bioradiotherapy (bio-RT). METHODS: In patients with stage III to IVb HPV-positive oropharyngeal cancer, the Kaplan-Meier analysis was used to calculate distant metastases rates...

Human papillomavirus (HPV) DNA is detected in up to 80% of oropharyngeal carcinomas (OPC) and this HPV positive disease has reached epidemic proportions. To increase our understanding of the disease, we investigated the status of the HPV16 genome in HPV-positive head and neck cancers (HNC). Raw RNA-Seq and Whole Genome Sequence data from The Cancer Genome Atlas HNC samples were analyzed to gain a full understanding of the HPV genome status for these tumors. Several remarkable and novel observations were made following this analysis...

BACKGROUND: Human papillomavirus (HPV) is a favourable prognostic factor in oropharyngeal cancer. Moreover, we and others reported that HPV-positive cancer of unknown primary in the head and neck region (HNCUP) has better outcome than HPV-negative HNCUP. However, not all studies concord. Here, our previous finding was investigated in a new cohort and additional biomarkers were analyzed. MATERIALS AND METHODS: A total of 19 HNCUPs diagnosed 2008-2013 were analyzed for HPV DNA by polymerase chain reaction assay (PCR) and p16 by immunohistochemistry (IHC)...

REVIEW
Marwah Abbas Hassan Aldalwg, Brian Brestovac
Human papillomavirus (HPV) associated head and neck squamous cell carcinomas (HNSCCs), have become a serious global health problem. Despite decreases in HPV-negative HNSCCs, the prevalence of HPV-positive HNSCCs has significantly increased. HPV-positive cancers are associated with superior survival outcomes when compared to HPV-negative cancers, which appears likely to be associated with differences in the molecular pathogenesis of the two diseases. While therapies are still problematic, the current HPV vaccine programs hold a promise for the primary prevention of HPV-related HNSCCs and since Australia was the first to introduce a nationwide HPV vaccine program, it is in a unique position to observe the effects of the vaccine on HNSCCs...

BACKGROUND: Molecular biomarkers assisting risk-group assignment and subsequent treatment stratification are urgently needed for patients with squamous cell cancer of the head and neck region (HNSCC). Aberrant methylation is a frequent event in cancer and, therefore, a promising source for potential biomarkers. Here, the methylation status of the paired-like homeodomain transcription factor 3 (PITX3) was evaluated in HNSCC. METHODS: Using a quantitative real-time PCR, PITX3 methylation was assessed in a cohort of 326 HNSCC patients treated for localized or locally advanced disease (training cohort)...

Human papilloma virus (HPV) has been recently recognised as a carcinogenic factor for a subset of head and neck cancers (HNC). In Europe, France has one of the highest incidence rates of HNC. The aim of this study is to explore changes in HNC incidence in France, potentially in relation with infection by HPV. HNC were classified into two anatomical groups: potentially HPV-related and HPV- unrelated. Trends over the period 1980-2012 were analysed by an age-period-cohort model based on data from eleven French cancer registries...

The emerging evidence showed that long noncoding RNAs (lncRNAs) are involved in cell growth and apoptosis as well as cancer progression and metastasis of malignant tumor, however, limited data are available on the role of lncRNAs in human papillomavirus (HPV)-associated Head and neck squamous cell carcinomas (HNSCC). Here, we demonstrated that 23.98% of 196 HNSCC cases in Southwest China could be classified as HPV16 infection. The number of MDSCs in HPV-positive HNSCC was significantly higher than normal control, indicating that HPV infection may promote MDSCs aggregation...

: 87 Background: HNC caused by HPV has become an epidemic. Treatment for HNC results in a tremendous symptom burden. The impact of HPV-status on quality of life (QOL) and how this effects illness perception and mood has not been described. We sought to explore differences in PROs in patients with HPV + vs. - HNC. METHODS: This is a secondary analysis of data from a prospective, longitudinal intervention study of 60 patients with newly diagnosed HNC undergoing concurrent chemoradiation...

PURPOSE: Human papillomavirus 16 (HPV-16) is important risk factor in Head and Neck Cancer (HNC). Studies suggest that microRNAs play an important role in cancer, however, their role in HPV mediated oncogenesis remains largely unknown. We investigated the role of microRNAs with HPV-16 as putative target in HPV-16 mediated cancers. EXPERIMENTAL DESIGN: Using in-silico tools, we identified microRNAs with putative binding sequences on HPV-16 mRNAs. Hsa-miR-139-3p was identified as best candidate miRNA by luciferase reporter assay and was found to be significantly down-regulated in HPV-16 positive tissues and cell lines...

PURPOSE OF REVIEW: In head and neck cancer management, immunoexpression of protein p16 is widely used as a surrogate marker for human papillomavirus (HPV) positivity due to challenges of direct HPV testing. Previously p16 has been reported to have good sensitivity but only moderate specificity in HPV-status determination. The aim of this review is to evaluate the existing information on sensitivity and specificity of p16 immunohistochemistry (IHC) in HPV-status determination among the recent studies...

EGFR inhibition and radiotherapy are potent inducers of DNA damage. Checkpoint kinases 1 and 2 (Chk1/2) are critical regulators of the DNA damage response, controlling cell cycle checkpoints which may permit recovery from therapy-associated genomic stress. We hypothesized that Chk1/2 inhibition (CHKi) with prexasertib may enhance cytotoxicity from EGFR inhibition plus radiotherapy in head and neck squamous cell carcinoma (HNSCC). In this study, we found that the addition of CHKi to the EGFR inhibitor cetuximab with and without radiotherapy significantly decreased cell proliferation and survival fraction in HPV positive and HPV negative HNSCC cell lines...

Oncogenic human papillomaviruses (HPVs) are closely linked to major human malignancies, including cervical and head and neck cancers. It is widely assumed that HPV-positive cancer cells are under selection pressure to continuously express the viral E6/E7 oncogenes, that their intracellular p53 levels are reconstituted on E6/E7 repression, and that E6/E7 inhibition phenotypically results in cellular senescence. Here we show that hypoxic conditions, as are often found in subregions of cervical and head and neck cancers, enable HPV-positive cancer cells to escape from these regulatory principles: E6/E7 is efficiently repressed, yet, p53 levels do not increase...

Head and neck (HN) carcinomas (mostly represented by squamous cell carcinomas [SCC]) still have a poor prognosis, which could be dramatically improved with immunotherapy. Tumor's microenvironment changes, caused by many endogenous or exogenous events, can correlate with prognosis and therapeutic response. Here, we review recent data regarding HNSCC, nasopharyngeal carcinomas (NPC) and salivary gland malignant tumors, all three being potential target of immunotherapies. About half of HNSCC exhibit PD-L1 expression, this expression being upregulated in HPV-positive tumors...

PURPOSE/OBJECTIVES: The increasing survivorship of head and neck squamous cell carcinoma (HNSCC) comes with a risk of death from other causes, known as competing causes. The demographics of HNSCC are also evolving with increasing incidence of Human Papillomavirus (HPV) associated tumors. This study describes competing causes of death for the HNSCC population compared to the general population and identifies associated risk factors. METHODS: Adult patients with first mucosal HNSCC (2004-2011) were identified from the Surveillance, Epidemiology and End Result database...

Human papillomavirus (HPV) causes oropharyngeal squamous cell carcinoma (OPSCC), although strongly divergent results have been reported regarding the prevalence of HPV16 in different countries, whether this represents important differences in etiology remains unclear. Applying rigorous protocols for sample processing, we centrally evaluated 1420 head and neck tumors (533 oropharynx, 395 oral cavity and 482 larynx) from studies conducted in the US, Europe and Brazil for mucosal HPV DNA and p16(INK4a) expression to evaluate regional heterogeneity in the proportion of HPV16-associated OPSCC and other head and neck cancer, and to assess covariates associated with the risk of HPV16-positive OPSCC...

Human papillomavirus (HPV), in addition to smoking and alcohol, is a cause of oropharyngeal squamous cell carcinoma (OPSCC), particularly of the tonsils and base of the tongue (TSCC and BOTSCC, respectively). Moreover, HPV-positive TSCC and BOTSCC are associated with a better outcome compared with their HPV-negative counterparts (80 vs. 40% 3-year disease-free survival rate, respectively) and their incidence has increased in several countries. Recently, accumulating evidence of HPV in a considerable proportion of cancers of unknown primary (CUP) in the head and neck region and in a small proportion of hypopharyngeal SCCs has been reported...
