BACKGROUND: This study examined the prognostic significance of human papillomavirus (HPV) in patients with oropharyngeal and oral cavity squamous cell carcinoma (SCC). METHODS: Tissue microarrays were constructed from oropharyngeal and oral cavity SCC (n=143). The presence of functional HPV in tumour was determined by combined assessments of p16 immunohistochemistry and HPV in-situ hybridisation. RESULTS: Oropharyngeal SCC patients presented with more advanced disease in comparison to oral cavity SCC patients (p=0...

Human papillomavirus (HPV) is a carcinogenic agent responsible for tumor development in many sexually involved tissues. We present a survey on the prevalence of HPV infection in a risk population for sexually transmitted infections (STIs). The studied population was formed by 125 STI clinic attendees, who took part in a screening program on STIs. To be included in the study the patients had to show no overt clinical signs of HPV infection. Genital (cervical in women, urethral in men), anal and oral samples were collected with ThinPrep liquid based cytology preparation system...

Human papillomavirus (HPV) is an independent risk factor for development of oral squamous cell carcinoma (OSCC). This study aimed to investigate the role of HPV infection and the trend in percentage of HPV-associated OSCC over a five-year period in northeastern Thailand. In this case-control study, 91 exfoliated oral cell samples and 80 lesion cell samples from OSCC cases and exfoliated oral cells from 100 age/gender-matched controls were collected. HPV infection was investigated by PCR using GP5+/GP6+ primers followed by HPV genotyping using reverse line blot hybridization...

Head and neck squamous cell carcinoma (HNSCC) is generalized term that encompasses a diverse group of cancers that includes tumours of the oral cavity (OSCC), oropharynx (OPSCC) and nasopharynx (NPC). Genetic alterations that are common to all HNSCC types are likely to be important for squamous carcinogenesis. In this study, we have investigated the role of the homeodomain-only homeobox gene, HOPX, in the pathogenesis of HNSCC. We show that HOPX mRNA levels are reduced in OSCC and NPC cell lines and tissues and there is a general reduction of HOPX protein expression in these tumours and OPSCCs...

Importance: Human papillomavirus (HPV) causes an increasing proportion of oropharyngeal squamous cell carcinomas (OPSCCs), particularly in white men. The prevalence of HPV among other demographic groups and other anatomic sites of HNSCC is unclear. Objective: To explore the role of HPV tumor status among women and nonwhites with OPSCC and patients with nonoropharyngeal head and neck squamous cell carcinoma (non-OP HNSCC). Design, Setting, and Participants: Retrospective cohort study at 2 tertiary academic centers including cases diagnosed 1995 through 2012, oversampled for minorities and females...

Importance: Pathology-based measures of human papillomavirus (HPV) status are routinely obtained in the care of head and neck cancer and are clearly associated with patient outcome for cancers of the oropharynx. However, it is unclear if HPV status is of high value for cancers of the larynx and oral cavity. In addition, it is possible to assess HPV infection using serology-based methods; however, the suitability of this pathology-independent measure for predicting patient outcome in head and neck cancer is unknown...

BACKGROUND: Oral cancer is one of the most common malignant lesions of the head and neck. This cancer is an aggressive and lethal disease with no significant improvements in the overall survival in the last decades. Moreover, the incidence of oral HPV-positive tumors is rising, especially in young people. This oral neoplasm develops through numerous molecular imbalances that affect key genes and signaling pathways; however, the molecular mechanisms involved in the pathogenesis and progression of oral tumors are still to be fully determined...

Cancer patients often show a wasting syndrome for which there are little therapeutic options. Dietary polyphenols have been proposed for treating this syndrome, but their usefulness in cases associated with human papillomavirus (HPV)-induced cancers is unknown. We characterized HPV16-transgenic mice as a model of cancer cachexia and tested the efficacy of long-term oral supplementation with polyphenols curcumin and rutin. Both compounds were orally administered to six weeks-old HPV16-transgenic mice showing characteristic multi-step skin carcinogenesis, for 24weeks...

Oral cavity cancer (OC) has steadily decreased in the United States (US) since 1973 whereas oropharyngeal cancer (OP) has increased. We analyzed OC and OP cases from the Oklahoma Central Cancer Registry and Surveillance, Epidemiology, and End Results program comparing those diagnosed from 1997-1999 to those diagnosed from 2010-2012. We compared the incidence of OC and OP cases between Oklahoma and the US and by demographic factors. We observed an increase in OP cases, but no change in OC cases in both the US and in Oklahoma, and observed some differences between Oklahoma and the US by race, gender, and age group...

INTRODUCTION: Human papillomavirus (HPV) infection is a cause of premalignant and malignant cancer in the lower genital and digestive tracts. In Brazil, there have been no prevalence studies that included a nationwide sample, and the prevalence of HPV has not been determined in many regions. METHODS: We will search the EMBASE, LILACS, MEDLINE, Web of Science and SciELO databases and previously published review articles to identify original research articles assessing HPV prevalence of the perineal (cervical, penile and anal) and oral areas...

The human papillomavirus (HPV) family has been associated with many cancers, including oral cancer. Recent studies have also revealed HPV presence from healthy adult and pediatric patient saliva samples, though much less is known about the oral prevalence of high-risk HPV in healthy children and adolescents. The primary goal of this project was to assess the prevalence of HPV within a pediatric dental clinic using non-invasively collected saliva. In brief, saliva was collected and DNA isolated to screen for HPV strains HPV6, HPV11, HPV16, and HPV18...

The incidence of oropharyngeal squamous cell carcinomas (SCCs) is increasing and is believed to reflect changing sexual practices in recent decades. For this case-case comparative study, we collected medical and life-style information and data on sexual behavior from 478 patients treated at the head and neck clinic of a tertiary hospital in Brisbane, Australia. Patients were grouped as (i) oropharyngeal SCC (n = 96), (ii) oral cavity, larynx and hypopharynx SCC ("other HNSCCs," n = 96), (iii) other SCCs (n = 141), and (iv) other diagnoses (n = 145)...

Squamous papillomas are common lesions occurring on skin, oral and nasal mucosa and male and female genital organs. Oral squamous cell papilloma (OSP) is a benign proliferation of the stratified squamous epithelium and is generally believed to be caused by Human Papilloma Viruses (HPV). It constitutes around 2.5% of all oral verruco-papillary lesions. We here, report a case of palatal OSP occurring in a 55-year-old male. The aetiological, clinical, diagnostic and treatment aspects of OSP are discussed here.

BACKGROUND: Vaccination is the primary strategy to reduce the burden of human papillomavirus (HPV) related diseases in the United States. Unvaccinated youth are at risk for HPV infection and associated diseases, and limited research has explored factors associated with HPV vaccination among those who are disadvantaged and at high risk, including lesbian, gay, bisexual, transgender and queer and/or homeless. METHODS: A retrospective electronic medical record review was conducted at an urban, homeless, and lesbian, gay, bisexual, transgender and queer focused health center in northeastern US logistic regression models examined the associations between HPV vaccination and demographic/social characteristics and health behaviors...

J T Guidry, R S Scott
The etiological role of human papillomavirus (HPV) in anogenital tract and head and neck cancers is well established. However, only a low percentage of HPV-positive women develop cancer, indicating that HPV is necessary but not sufficient in carcinogenesis. Several biological and environmental cofactors have been implicated in the development of HPV-associated carcinoma that include immune status, hormonal changes, parity, dietary habits, tobacco usage, and co-infection with other sexually transmissible agents...

Human papillomavirus (HPV) has been found in several regions of the body, including the oral cavity. Recently, this virus has been associated with oropharyngeal cancer, but little is known about HPV transmission to the oral cavity. We carried out a study to investigate concurrent oral and cervical infections in 76 asymptomatic women attending a healthcare program. Demographic and behavior data were obtained through a structured questionnaire. Oral and cervical mucosa scrapings were collected and stored for DNA extraction...
