BACKGROUND: Human papilloma virus (HPV) has been implicated in the development of a large proportion of oropharyngeal squamous cell carcinoma (OPSCC). Current techniques used to diagnose HPV etiology require histopathologic analysis. We aim to investigate the diagnostic accuracy of a new application non-histopathologic diagnostic tests to help assist diagnosis of HPV-related oropharyngeal tumors. METHODS: Patients with OPSCC with nodal metastasis were consecutively recruited from a multidisciplinary cancer clinic...

Various hypotheses have been put forward on the pathogenesis of squamous cell carcinoma (SCC), including chronic sun damage and exposure to ultraviolet radiation (UVR), chemicals, smoking, immunosuppressive medications and human papillomavirus (HPV)(1) . It is well known that alpha (mucosal) HPV types, in particular HPV-16 and HPV-18, are etiologically correlated to cervical cancer and other types of anogenital carcinoma and oropharyngeal papillomatosis(1) . On the contrary, the pathogenesis of squamous cell carcinoma (SCC) outside the mucosae remains obscure, and the link with HPVs has been demonstrated only in the epidermodysplasia verruciformis context(2-3) ...

Human papillomavirus (HPV) DNA is detected in up to 80% of oropharyngeal carcinomas (OPC) and this HPV positive disease has reached epidemic proportions. To increase our understanding of the disease, we investigated the status of the HPV16 genome in HPV-positive head and neck cancers (HNC). Raw RNA-Seq and Whole Genome Sequence data from The Cancer Genome Atlas HNC samples were analyzed to gain a full understanding of the HPV genome status for these tumors. Several remarkable and novel observations were made following this analysis...

BACKGROUND: p16 overexpression and wild-type p53 expression is associated with human papilloma virus (HPV) in cervical and oropharyngeal cancer. Role of HPV-related carcinogenesis in the etiology of oral squamous cell carcinoma (OSCC) is still vague in Indian population. We aimed to explore the expression pattern of p16 and p53 in HPV positive and HPV negative OSCC to elicit differences, if any. Further their effect on survival of patients was studied. METHODS: Thirty-one consecutive HPV positive as well as 31 age and sex matched HPV negative OSCC cases from a case series of 369 histologically diagnosed cases of OSCC were included in this study...

Prior studies established constitutively active AP-1, NF-κB, and STAT3 signaling in oral cancer. Differential expression/activation of specific members of these transcription factors has been documented in HPV-positive oral lesions that respond better to therapy. We performed a comprehensive analysis of differentially expressed, transcriptionally active members of these pivotal signaling mediators to develop specific signatures of HPV-positive and HPV-negative oral lesions by immunohistochemical method that is applicable in low-resource settings...

Epigenetic modifications are heritable changes in gene expression that do not directly alter DNA sequence. These modifications include DNA methylation, histone post-translational modifications, small and non-coding RNAs. Alterations in epigenetic profiles cause deregulation of fundamental gene expression pathways associated with carcinogenesis. The role of epigenetics in oropharyngeal squamous cell carcinoma (OPSCC) has recently been recognized, with implications for novel biomarkers, molecular diagnostics and chemotherapeutics...

High-risk human papillomaviruses (HPVs) are known to be associated with different anogenital cancers including cervical, anal, penile, and vaginal cancers. They are also found to be responsible for the dramatic increases in oropharyngeal squamous cell carcinoma (OPSCC) observed in the United States and Europe. The model for how high-risk HPVs induce cancer formation comes from studies of cervical cancer which usually involves integration of the HPV into the human genome and subsequent changes due to induced chromosomal instability...
