Cervical cancer is the third highest cause of death in developing countries and most commonly results from high‑risk human papillomavirus (HR‑HPV) infection. Among HR‑HPV genotypes, HPV16 and HPV18 are the most prevalent in cervical cancers. Therefore, the present study aimed to develop a detection assay for HPV16 and HPV18 infection using loop‑mediated isothermal amplification (LAMP) with lateral flow dipstick (LFD) tests. This assay is a simplified, user‑friendly method for the visual detection of HPV genotypes...

Cervical cancer is the fourth most common cause of cancer-related death in women worldwide and new therapeutic approaches are needed to improve clinical outcomes for this group of patients. Current treatment protocols for locally advanced and metastatic disease consist of ionising radiation and chemotherapy. Chemoradiation induces cytotoxic levels of DNA double-strand breaks, which activates programmed cell death via the DNA damage response (DDR). Cervical cancers are unique given an almost exclusive association with human papillomavirus (HPV) infection; a potent manipulator of the DDR, with the potential to alter tumour sensitivity to DNA-damaging agents and influence treatment response...

Patients with neck squamous cell carcinomas of unknown primary tumour (NSCCUP) present with lymph node metastasis without evidence for a primary tumour. Most patients undergo an aggressive multimodal treatment, which induces severe, potentially unnecessary toxicity. Primary tumours of NSCCUP can be hidden in the oropharynx. Human papillomavirus (HPV) is causally involved in a subgroup of oropharyngeal squamous cell carcinomas (OPSCC) associated with early lymph node metastasis and good prognosis. Detection of markers for HPV transformation in NSCCUP could allow focussing on the oropharynx in primary tumour search and could be of value for choice and extent of treatment...

Importance: Human papillomavirus (HPV) vaccination is recommended for children and younger adults but not older adults or those with prior HPV exposure, leaving a large portion of the population at risk for HPV-mediated disease. Emerging data suggest a possible role for vaccination as an adjuvant treatment for individuals with HPV-related clinical disease. Objective: To systematically review the literature regarding HPV vaccination for secondary disease prevention after treatment of active clinical disease across disease sites to serve as a platform for the management of HPV-related disease of the head and neck...

REVIEW
Sixto M Leal, Margaret L Gulley
Laboratory tests have a key role in preventing human papillomavirus (HPV)-driven carcinomas and in guiding therapeutic interventions. An understanding of the virology, immunology, and carcinogenesis of HPV is essential for choosing appropriate diagnostic test modalities and developing new and even more effective cancer prevention strategies. HPV infects basal epithelial cells on multiple surfaces and induces carcinoma primarily in the cervix and the oropharynx. HPV types are stratified as high risk or low risk based on their carcinogenic potential, driven largely by viral interference with cell cycle regulation and the DNA damage response to promote continuous cell division while thwarting apoptosis, which enables mutation accumulation...

The purpose of this study was to evaluate if an early exposure to human papillomavirus (HPV) during the prenatal period or infancy could result in HPV16-specific T helper (Th) responses resembling those of adults with HPV-induced lesions. We tested HPV16-specific cell-mediated immunity (CMI) in children born with HPV-positive umbilical cord blood and/or placenta or having persistent oral HPV infection and in constantly oral HPV-negative controls. Peripheral blood mononuclear cells from 33 children from the Finnish HPV Family Study cohort (mean age 14...

Head and neck squamous cell carcinoma (HNSCC) is broadly classified into HNSCC associated with human papilloma virus (HPV) infection, and HPV negative HNSCC, which is typically smoking-related. A subset of HPV negative HNSCCs occur in patients without smoking history, however, and these etiologically 'atypical' HNSCCs disproportionately occur in the oral cavity, and in female patients, suggesting a distinct etiology. To investigate the determinants of clinical and molecular heterogeneity, we performed unsupervised clustering to classify 528 HNSCC patients from The Cancer Genome Atlas (TCGA) into putative intrinsic subtypes based on their profiles of epigenetically (DNA methylation) deregulated genes...

Detection of active human papillomavirus (HPV) is clinically important, as its presence has been shown to correlate with favorable clinical outcomes and better response to treatment in oropharyngeal squamous cell carcinomas (SCC). Using a clinical automated platform, we compared the performance of commercially available HPV DNA and RNA in situ hybridization (ISH) probes in archival tissues of 57 SCC. Importantly, a clinical automated platform gives 1) consistent and reproducible results for HPV ISH and 2) better standardization across clinical laboratories...

The fourth edition of the World Health Organization classification set up new entities of endocervical adenocarcinoma (ECA), namely the "usual type" and "gastric type." These 2 types are considered to be distinct histogenetically because of their differing immunophenotypes, human papillomavirus (HPV) status, and prognoses. Usual-type ECAs (U-ECAs) are virtually always associated with high-risk human papillomavirus (HR-HPV) infection. Gastric-type ECAs (G-ECAs) are believed not to be associated with HR-HPV infection...

A third to half of penile invasive squamous cell carcinomas are human papillomavirus (HPV) related. Warty (condylomatous), warty-basaloid, and basaloid carcinomas are the most common subtypes associated with HPV. Less frequent are clear cell and lymphoepithelioma-like carcinomas. Here we report a novel penile tumor associated with HPV. Twelve cases were selected from 1010 penile carcinomas, part of an international HPV detection study conducted at the Institut Català d'Oncologia, Barcelona, Spain. Immunostaining with p16 was performed on all cases, and HPV-mRNA detection was also performed...

BACKGROUND: Human papillomavirus (HPV) is the carcinogen of almost all invasive cervical cancer and a major cause of oral and other anogenital malignancies. HPV genotyping by dideoxy (Sanger) sequencing is currently the reference method of choice for clinical diagnostics. However, for samples with multiple HPV infections, genotype identification is singular and occasionally imprecise or indeterminable due to overlapping chromatograms. Our aim was to explore and compare HPV metagenomes in abnormal cervical cytology by deep sequencing for correlation with disease states...

There is plenty of substantial evidence to support anti-tumor activity of viruses. Adeno-associated virus (AAV) may interact with human papillomavirus (HPV) to modify the risk of cervical neoplasia. The seroprevalence of AAV among women with cervical cancer has been reported to be lower than healthy ones. In spite of this finding, detection of AAV DNA in cervical biopsies does not entirely support the inverse association between AAV seropositivity and cervical cancer. This association is still controversial and requires more thorough evaluation in different countries...
