Squamous cell carcinoma of the head and neck (SCCHN) comprises a large group of cancers in the oral cavity and nasopharyngeal area that typically arise in older males in association with alcohol/tobacco usage. Within the oral cavity, the mobile tongue is the most common site for tumour development. The incidence of tongue squamous cell carcinoma (TSCC) is increasing in younger people, which has been suggested to associate with a viral aetiology. Two common human oncogenic viruses, human papilloma virus (HPV) and Epstein-Barr virus (EBV) are known causes of certain types of SCCHN, namely the oropharynx and nasopharynx, respectively...

Oral squamous cell carcinoma (OSCC) is the commonest subtype of oral cancer, mainly affecting older patients. It used to be a rare disease among individuals younger than 40 years, but recently increased incidences in this age group are being reported worldwide. The pathogenesis of OSCC affecting young patients remains controversial and the well known etiological factors for oral cancer, tobacco and alcohol use, are believed to play a minor role in the carcinogenesis of the neoplasm, suggesting that the etiology and the molecular basis of OSCC may differ between younger and older patients...

Cervical cancer is the second most common cancer in women worldwide. Human papillomavirus (HPV) is considered as the main cause of invasive cervical cancer and cervical intra-epithelial neoplasia. High risk HPV DNA has been shown to be present in 99.7% of cervical cancers. So HPV DNA testing for screening of cervical cancers may play a potential role in early detection and management of cervical cancer. With above background a cross sectional study was undertaken to estimate the prevalence and to identify the associated risk factors of human Papillomavirus infection among Visual Inspection with Acetic acid (VIA) positive women attending at colposcopy clinic of Mymensingh Medical College Hospital (MMCH), Mymensingh, Bangladesh from July 2013 to December 2014...

PURPOSE: DNA methylation in human papillomavirus-associated (HPV+) head and neck squamous cell carcinoma (HNSCC) may have importance for continuous expression of HPV oncogenes, tumor cell proliferation and survival. Here, we determined activity of a global DNA demethylating agent, 5-azacytidine (5-aza), against HPV+ HNSCC in pre-clinical models and explored it as a targeted therapy in a window trial enrolling patients with HPV+ HNSCC. EXPERIMENTAL DESIGN: Sensitivity of HNSCC cells to 5-aza treatment was determined, then 5-aza activity was tested in vivo using xenografted tumors in a mouse model...

BACKGROUND AND PURPOSE: Clinical studies indicate that patients with HPV/p16-associated head & neck squamous cell carcinoma (HNSCC) represent a subgroup with a better prognosis and improved response to conventional radiotherapy. Involvement of immune-based factors has been hypothesized. In the present study, we investigated radiation-induced differences in release of damage associated molecular patterns (DAMPs), cytokines and activation of dendritic cells (DCs) in HPV-positive and negative HNSCC cancer cell lines...

BACKGROUND AND PURPOSE: Head and neck squamous cell carcinoma associated with human papillomavirus infection represents a distinct tumor entity. We hypothesized that diffusion phenotypes based on the histogram analysis of ADC values reflect distinct degrees of tumor heterogeneity in human papillomavirus-positive and human papillomavirus-negative head and neck squamous cell carcinomas. MATERIALS AND METHODS: One hundred five consecutive patients (mean age, 64 years; range, 45-87 years) with primary oropharyngeal (n = 52) and oral cavity (n = 53) head and neck squamous cell carcinoma underwent MR imaging with anatomic and diffusion-weighted sequences (b = 0, b = 1000 s/mm(2), monoexponential ADC calculation)...

REVIEW
Xun Chen, Yu Zhao
Human papillomavirus (HPV) infects keratinocytes in the mucosa or skin, and persistent infection with HPV may lead to premalignant lesions and invasive cancer, especially cervical cancer. It has also been hypothesized that HPV infection is an etiological factor of oral squamous cell carcinoma and oral precancerous disorders such as lichen planus, leukoplakia, and erythroplakia. A high percentage of HPV in oral lesions supports the possible viral contribution, but an association of HPV infection with these lesions remains to be established...

The tumor suppressor gene TP53 is the most frequently mutated gene in human papillomavirus (HPV)-negative head and neck squamous cell carcinoma (HNSCC). It represents a known transcription factor that controls different microRNAs (miRNA) and target genes involved in the regulation of cellular stress, apoptosis and response to DNA damage. We used The Cancer Genome Atlas database to investigate the difference in transcriptome and proteome levels between mutated and wild-type TP53 HPV-negative HNSCC. Using different databases and an extensive literature review, we built the transcriptional and post-transcriptional network regulated by TP53...

High-risk human papillomaviruses (hr HPVs) may cause various human cancers and associated premalignant lesions. Transformation of the host cells is triggered by overexpression of the viral oncogenes E6 and E7 that deregulate the cell cycle and induce chromosomal instability. This process is accompanied by hypermethylation of distinct CpG sites resulting in silencing of tumor suppressor genes, inhibition of the viral E2 mediated control of E6 and E7 transcription as well as deregulated expression of host cell microRNAs...

HPV-positive oropharyngeal cancer patients experience significantly lower locoregional recurrence and higher overall survival in comparison with HPV-negative patients, especially among those who received radiation therapy. The goal of the present study is to investigate the molecular mechanisms underlying the differential radiation sensitivity between HPV-negative and HPV-positive head and neck squamous cell carcinoma (HNSCC). Here, we show that HPV-negative HNSCC cells exhibit increased glucose metabolism as evidenced by increased production of lactate, while HPV-positive HNSCC cells effectively utilize mitochondrial respiration as evidenced by increased oxygen consumption...

The possible association between high-risk human papillomaviruses (HPV) and lung cancer has been investigated for decades but the results are quite discrepant. This study aimed to screen Bulgarian lung cancer patients for the prevalence of HPV16 and 18. We analyzed 209 biopsy specimens from patients with histologically proven lung cancer and non-cancer cases. Each sample was subjected to three parallel PCRs using broad spectrum GP5+/6+ primers and type-specific (TS) primers for HPV types 16 and 18. Of the 132 lung carcinoma samples 33(25 %) were positive for HPV16 and/or HPV18 by TS PCR and only 5(3...

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) is the sixth most prevalent cancer worldwide with rates of HPV-positive oropharyngeal squamous cell carcinoma (OPSCC) dramatically increasing. The overexpression of enhancer of zeste homolog 2 (EZH2), a histone methyltransferase responsible for the trimethylation at lysine 27 of histone 3 (H3K27me3), is associated with a poor clinical prognosis and aggressive HPV-positive phenotypes. METHODS: We utilized three EZH2 pathway inhibitors, GSK-343, DZNeP, and EPZ-5687, and tested their efficacy in two HPV-positive and two HPV-negative OPSCC cell lines...

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC), originally known as HPV-related carcinoma with adenoid cystic carcinoma-like features, is a peculiar neoplasm that is restricted to the sinonasal tract, exhibits features of both a surface-derived and salivary gland carcinoma (particularly adenoid cystic carcinoma), and is associated with high-risk HPV. Given the limited number of published cases, the full clinicopathologic spectrum of this neoplasm is unclear. Here, we present an updated experience of 49 cases...

The oral cavity and oropharynx have historically been viewed as a single anatomic compartment of the head and neck. The practice of combining the oral cavity and oropharynx has recently been revised, largely owing to the observation that human papillomavirus (HPV)-related carcinogenesis has a strong predilection for the oropharynx but not the oral cavity. The purpose of this study was to determine whether HPV is evenly distributed across squamous cell carcinomas of the oropharynx including those sites that do not harbor tonsillar tissues such as the soft palate...
