Infection with high-risk human papillomavirus (HPV), most often HPV16, is associated with the development of anogenital and oropharyngeal cancers. Recently, ozone therapy was reported to have considerable efficacy against rabbit VX2 tumors, induced by the cottontail rabbit papillomavirus. The present study aims to determine whether similar results can be obtained in HPV16-transgenic mice, possibly paving the way for new therapeutic options against HPV-induced cancers. HPV16-transgenic and wild-type, female, 20 weeks-old mice were injected intraperitoneally with medical O3 /O2 (80░mL/kg, at O3 50░μg/mL), once a day, for 5 consecutive days...

Head and neck cancers are the sixth most common cancers worldwide and an important cause of ill health.(1) Each year about 9000 cases are reported in the UK.(2) Survival is poor and despite advances in treatment, has not improved until recently.(3) The majority of head and neck cancers are squamous cell carcinomas, affecting the larynx, oropharynx and oral cavity. The aetiology is changing and this has implications for prevention and treatment. Twenty years ago, tobacco and alcohol consumption were considered to be the established risk factors and it was estimated that these risk factors accounted for about 75% of cases...

BACKGROUND: The incidence of human papillomavirus-induced (HPV+) head and neck squamous cell carcinoma (HNSCC) i.e. especially oropharyngeal cancers (OPSCC) is increasing and a significant proportion of patients encounter disease progression. A simple and sensitive test to identify patients with progression is an unmet need. OBJECTIVE OF REVIEW: To systematically review the literature and carry out a meta-analysis of studies, investigated circulating HPV-DNA as a biomarker for disease progression in patients with HNSCC...

Human papillomavirus (HPV) infections are responsible for a significant part of the global burden of cancer. Epidemiologic studies have shown increasing trends of HPV-related oral cancers worldwide. Dental professionals need comprehensive up-to-date HPV-related information to be able to provide correct advice to their patients. The aim of this paper is to describe knowledge and awareness levels of dental students from Spain on HPV infection, HPV vaccination, oral cancer prevention, and HPV-related oropharyngeal cancer...

BACKGROUND: HPV-associated OSCC (HPV-OSCC) has been determined to be a distinct disease entity from non-HPV associated OSCC. Patients affected by HPV-OSCC generally have a more favourable prognosis, with improved rates of locoregional control and survival compared with their non-HPV counterparts. Despite this, HPV-OSCC has a similar rate of distant metastases. Interestingly, recent evidence has emerged that demonstrates more frequent atypical metastasis patterns when compared to non-HPV associated disease...

CONCLUSIONS: We did not identify any strong associations between HPV-16 viral load and any of the clinical or lifestyle factors. OBJECTIVE: The epidemiology of oropharyngeal SCC is changing, with an increasing proportion of HPV-positive cases seen in the last decade. It is known that a high viral load is linked to the development of cervical cancer, the relation between viral load and oropharyngeal SCC is less clear. We sought to determine HPV-16 viral load in HPV-positive oropharyngeal SCCs using highly sensitive digital PCR and to identify clinical and lifestyle factors associated with viral load...

High-risk human papillomavirus (HPV) infection is the etiological agent of cervical, oral and oropharyngeal cancers. Another oncogenic virus, Kaposi sarcoma-associated herpesvirus (KSHV) can cause several human cancers arising in those immunocompromised patients. KSHV DNA has been detected in the oral cavity and the female genital tract, although its detection rate in cervical samples is relatively low. Therefore, it remains unclear about the role of KSHV co-infection in the development of HPV-related neoplasia...

The definition of nodal and/or mucosal target volumes for radiation therapy for lymphadenopathies of unknown primary is controversial. Target volumes may include all nodal areas bilaterraly and be pan-mucosal or unilateral, selective, including the sole oropharyngeal mucosa. This review presents current recommendations in light of changes in the TNM classification, Human papillomavirus status and therapeutic advances. We conducted a systematic review of the literature with the following keywords: lymphadenopathy; head and neck; unknown primary and radiation therapy...

Oropharyngeal cancer incidence increased dramatically in the last decades, being infection with human papillomaviruses (HPV) a determinant of this trend. Concerning etiology, treatment response and prognosis, HPV+ and HPV- oropharyngeal cancers constitute different disease entities. The underlying molecular background is not completely understood. ATP-binding cassette (ABC) transporters mediate the efflux of anticancer drugs and are regulated by changes in the intracellular milieu. Furthermore, a role in cancer pathogenesis besides drug transport was reported...

BACKGROUND: Human papilloma virus (HPV)-negative oropharyngeal squamous cell carcinomas (OPCs) have a poorer prognosis and best management is an unmet need. We studied the prognostic role of epidermal growth factor receptor (EGFR) and PIK3CA amplifications and TP53 functional status. METHODS: Between 1992 and 2000, 90 consecutive patients with OPCs were treated with surgery, followed by radiotherapy in case of high-risk pathologic features. Of those, 73 cases were HPV-negative and therefore were selected for molecular analysis ( PIK3CA and EGFR fluorescent in situ hybridization [FISH] analysis and TP53 mutation analysis)...

The incidence of HPV-positive oropharyngeal cancer (HPV+ OPC) is increasing, thus presenting new challenges for disease detection and management. Noninvasive methods involving brush biopsies of diseased tissues were recently reported as insufficient for tumor detection in HPV+ OPC patients, likely due to differences between the site of tumor initiation at the base of involuted crypts and the site of brush biopsy at the crypt surface. We hypothesized that histologically normal surface epithelial cells in the oropharynx contain changes in nuclear morphology that arise due to tumor proximity...

BACKGROUND: The incidence of oropharyngeal squamous cell carcinoma (OPSCC) is increasing among older adults. It is unknown whether these trends can be explained by human papillomavirus (HPV) and whether HPV-related tumors remain associated with an improved prognosis among older patients. METHODS: In a retrospective study of OPSCCs diagnosed from 1995 to 2013 at 2 National Comprehensive Cancer Network-designated cancer centers, p16 immunohistochemistry and in situ hybridization (ISH) for HPV-16, high-risk DNA, and/or E6/E7 RNA were performed...

Importance: Clinical trials that deintensify treatment for patients with suspected human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC) use p16 expression to identify HPV-mediated tumors and guide treatment. While p16 staining has a strong correlation with good outcomes, approximately 12% of p16-positive patients have recurrent disease. Biomarkers that reveal tumor-specific characteristics, such as nodal involvement, may change therapy decisions. Objective: To assess whether if a tumor-specific genetic signature exists for node-negative vs node-positive HPV 16-positive/p16-positive OPSCCs...

A significant proportion of mucosal squamous cell carcinomas of the head and neck (HNSCC; particularly of the oropharynx) are directly attributable to the human papillomavirus (HPV). The increase in the incidence of HPV-related tumours has been postulated to be due to changing sexual practices in the community. We analysed 136 formalin-fixed paraffin-embedded squamous cell carcinomas from the oral cavity (n=40) and oropharynx (n=96) recruited from the Princess Alexandra Hospital (Brisbane, Australia). Samples were analysed for the presence of HPV DNA using a combination of mucosal HPV general primer GP+ PCR and sequencing; p16INK4a expression was assessed by immunohistochemistry...

BACKGROUND: Human papillomavirus (HPV) can cause cervical, other genital, anal, head, and neck cancers. The incidence of oropharyngeal squamous cell carcinoma (OSCC), the head and neck cancer most commonly caused by HPV infection, is increasing. The prevalence of oral HPV infections is considerably lower than that of genital HPV infections; however, infection of both sites is strongly associated with sexual behavior. Although the natural histories of cervical and oral HPV infections do not markedly differ, the virus seems to rarely infect oral and genital sites simultaneously...
