BACKGROUND: More than 400,000 cases of oropharyngeal squamous cell cancer (OPSCC) are diagnosed every year worldwide and this is rising. Much of the increase has been attributed to human papillomavirus (HPV). HPV-positive OPSCC patients are often younger and have significantly improved survival relative to HPV-negative patients. Traditional management of OPSCC has been with radiotherapy with or without chemotherapy, as this was shown to have similar survival to open surgery but with significantly lower morbidity...

Standardized, synoptic pathologic reporting for tumors greatly improves communication among clinicians, patients, and researchers, supporting prognostication and comparison about patient outcomes across institutions and countries. The International Collaboration on Cancer Reporting is a nonprofit organization whose mission is to develop evidence-based, universally available surgical pathology reporting data sets. Within the head and neck region, lymph node excisions and neck dissections are frequently performed as part of the management of head and neck cancers arising from the mucosal sites (sinonasal tract, nasopharynx, oropharynx, hypopharynx, oral cavity, and larynx), along with bone tumors, skin cancers, melanomas, and other tumor categories...

Background/Aims: Since patients with human papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) have favorable outcomes after treatment, treatment de-escalation for these patients is being actively investigated. However, not all HPV-positive HNSCCs are curable, and some patients have a poor prognosis. The purpose of this study was to identify poor prognostic factors in patients with HPV-positive HNSCC. Methods: Patients who received a diagnosis of HNSCC and tested positive for HPV from 2000 to 2015 at a single hospital site (n = 152) were included in this retrospective analysis...

REVIEW
Keegan M Lyons, Samantha L Butler
Anal squamous cell carcinoma is a relatively rare diagnosis, but its incidence has continued to rise. Anal squamous cell carcinoma and its precursor lesion, anal intraepithelial neoplasia (AIN), are human papillomavirus (HPV)-associated squamous neoplasias. High-risk HPV subtypes cause cellular proliferation in the anal transformation zone mucosa leading to similar dysplastic changes as seen in the cervix. Unified cytologic and histologic classification systems have emerged for all HPV-associated squamous lesions of the lower anogenital tract due to recent advancements in the understanding of these lesions...

Histological grading of squamous intraepithelial lesions or intraepithelial neoplasia is fundamental for clinical management and for assessment of the risk of progression. Biomarkers are important for assisting correct grading of these lesions, reducing inter and intraobserver variability and most promising, for prognosis. Although p16 is the most studied biomarker in this setting, there are several other biomarkers that have been studied, reflecting also the need to find a better single or association option that can be more suitable, especially for classification purposes...

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...

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...
