Locally advanced head and neck squamous cell carcinomas (HNSCC) have limited prognosis due to frequent treatment failure. Currently, TNM-classification and human papillomavirus (HPV) infection are the sole clinical prognosticators of outcome. Tumor heterogeneity and stemness based on epithelial-mesenchymal-transition reportedly associate with therapy resistance. The capacity of epithelial marker EpCAM (EpEX), stemness regulator Sox2 and mesenchymal marker vimentin to predict clinical outcome of HSNCC patients was assessed upon immunohistochemistry staining in two cohorts of HNSCC patients treated with surgery and adjuvant radio (chemo) therapy (n = 94) and primary radio (chemo) therapy (n = 94), respectively...

OBJECTIVE: Recently, the pattern of invasion in usual-type human papillomavirus-associated endocervical adenocarcinoma (AC) was put forward as a novel variable to select patients with favourable prognosis. Based on destructiveness of stromal invasion, three patterns were proposed: A - no destructive stromal invasion, B - focal destructive stromal invasion, and C - diffuse destructive stromal invasion. We aimed to independently validate the clinical significance of this classification-system in 82 AC patients, and explored associations between invasion pattern and somatic mutations...

BACKGROUND:  Human papillomavirus (HPV) infection plays an important role in the pathogenesis of penile squamous cell carcinoma (PSCC) in about one third of the affected patients. Initial data indicate that HPV status could facilitate optimised risk stratification and individualised targeted therapy. The polymerase chain reaction (PCR) assay is the reference method for detection of HPV DNA. It is unclear if alternatives such as in situ hybridisation (ISH) or various surrogate markers (defined as immunohistochemical detection of p16INK4a, histological subtype, tumour invasion front, koilocytosis) are sufficient to determine HPV status METHODS:  In this single centre study on 34 patients with PSCC, multiplex nested PCR and ISH were conducted for HPV detection and identification of HPV DNA genotypes...

OBJECTIVES: Approximately 3% to 9% of head and neck cancer presents with a metastatic node and no identifiable primary tumor. These cases of head and neck carcinoma of unknown primary (HNCUP) present a therapeutic challenge. Therapy of this disease varies based on factors such as institutional, surgeon, and patient preference. Evidence demonstrating the outcomes associated with these therapies for HNCUP is limited, and among the available series, the tumor human papillomavirus (HPV) status is often ignored...

Head and neck squamous cell carcinomas (HNSCCs) arise in the mucosal lining of the upper aerodigestive tract. Tobacco and alcohol use have been reported to be associated with HNSCC. Infection with high-risk human papillomaviruses (HPVs) has recently been implicated in the pathogenesis of HNSCCs. It is now widely accepted that high-risk HPV is a cause of almost all cervical cancers as well as some forms of HNSCCs. HPV-related HNSCCs are increasing. HPV-related HNSCCs and HPV-unrelated HNSCCs differ with respect to the molecular mechanisms underlying their oncogenic processes...

OBJECTIVES: The incidence of human papillomavirus (HPV) positive oropharyngeal squamous cell carcinoma (OPSCC) is increasing. Currently, data is sparse on the pattern and timing of recurrence. This long-term study concerning both HPV- and p16-status aimed to report predictive factors, pattern, timing of loco-regional recurrence (LRR) and distant recurrence (DR), and survival following recurrence in patients diagnosed with OPSCC. MATERIAL AND METHODS: We included patients diagnosed with OPSCC from 2000 to 2014 in Eastern Denmark, who were treated with curative intent...

Background: With the growing interest in treatment de-intensification trials for human papillomavirus positive (HPV+) oropharyngeal squamous cell carcinoma (OPC), prognostic models have become essential for patient selection. The aim of this paper is to validate and compare the prognostic ability of the TNM 8th edition and previous published risk group classifications of Ang et al. and Rietbergen et al. and to derive a patient selection classification for de-intensification trials. Materials: Patients with HPV+ OPC treated with curative (chemo)radiotherapy between 2004 and 2017 were classified according to the TNM 8th edition, the model of Ang et al...

BACKGROUND: Although human papillomavirus (HPV) is considered as a causative factor in oral squamous cell carcinoma (OSCCs), its pathogenetic role is not well established. Moreover, a limited number of studies have compared the techniques of detecting the HPV infection in OSCC. This study aimed at the detection of HPV 16 E6 and E7 DNA in OSCC by quantitative polymerase chain reaction (qPCR) technique. METHODOLOGY: This retrospective study included 297 tissue sections obtained from histopathologically confirmed OSCC patients...

Vulvar squamous cell carcinoma (VSCC) and precancerous vulvar intraepithelial neoplasia (VIN) can develop through human papillomavirus (HPV)-dependent and -independent pathways, indicating a heterogeneous disease. Only a minority of VIN progress, but current clinicopathological classifications are insufficient to predict the cancer risk. Here we analyzed copy number alterations (CNA) to assess the molecular heterogeneity of vulvar lesions in relation to HPV and cancer risk. HPV-status and CNA by means of whole-genome next-generation shallow-sequencing were assessed in VSCC and VIN...

BACKGROUND: Surveillance, Epidemiology, and End Results Cancer Registries (SEER) began collecting human papillomavirus (HPV) status for upper aerodigestive tract cancers in 2010. However, classification of p16-testing was not included in the Collaborative Stage coding guidelines, potentially leading to inconsistent coding. METHODS: The HPV values for Iowa patients with oropharyngeal cancers (n = 824) were recoded based on modified guidelines that included p16 test results, and compared with the original guidelines...

The Papillomaviridae is a family of small, non-enveloped viruses with double-stranded DNA genomes of 5 748 to 8 607 bp. Their classification is based on pairwise nucleotide sequence identity across the L1 open reading frame. Members of the Papillomaviridae primarily infect mucosal and keratinised epithelia, and have been isolated from fish, reptiles, birds and mammals. Despite a long co-evolutionary history with their hosts, some papillomaviruses are pathogens of their natural host species. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Papillomaviridae, which is available at http://www...

OBJECTIVES: Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors - especially oropharyngeal cancer - are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. METHODS: Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014...

The current World Health Organization (WHO) classification for endocervical adenocarcinoma (EA) is based on descriptive morphologic characteristics; however, it does not fully reflect our current knowledge of the diverse pathogenesis of cervical glandular neoplasia. A novel classification system, the International Endocervical Adenocarcinoma Criteria and Classification (IECC), which incorporates etiology and biological behavior into the morphologic scheme, has been recently proposed. We aimed to validate the IECC by assessing its interobserver reproducibility in comparison to the WHO system...

The self-controlled tree-temporal scan statistic-a new signal-detection method-can evaluate whether any of a wide variety of health outcomes are temporally associated with receipt of a specific vaccine, while adjusting for multiple testing. Neither health outcomes nor postvaccination potential periods of increased risk need be prespecified. Using US medical claims data in the Food and Drug Administration's Sentinel system, we employed the method to evaluate adverse events occurring after receipt of quadrivalent human papillomavirus vaccine (4vHPV)...

Primary penile cancer is a rare disease. Higher incidence rates occur in underdeveloped countries. Many studies have suggested an association between human papillomavirus (HPV) infection and penile cancer. Although HPV can affect the squamous epithelium of the male genitalia similarly to the female genital tract, the association between penile cancer and HPV remains unclear. In the present study, the HPV gene expression was examined in penile cancer tissue using in situ hybridization (ISH). The present study included 41 cases in which penectomy was performed and 3 cases in which tumor resection was performed to treat pathologically-diagnosed penile cancer at Yokohama City University Medical Center, and its 7 affiliated hospitals between April 1990 and March 2010...

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...
