BACKGROUND: We aimed at identifying deleterious genomic alterations from untreated head and neck squamous cell carcinoma (HNSCC) patients, and assessing their prognostic value. PATIENTS AND METHODS: We retrieved 122 HNSCC patients who underwent primary surgery. Targeted NGS was used to analyse a panel of 100 genes selected among the most frequently altered genes in HNSCC and potential therapeutic targets. We selected only deleterious (activating or inactivating) single nucleotide variations, and copy number variations for analysis...

Human papilloma virus (HPV) is a known cause of cervical cancer, squamous cell carcinoma and laryngeal cancer. Although treatments exist for HPV-associated malignancies, patients unresponsive to these therapies have a poor prognosis. Recent findings from vaccine studies suggest that T-cell immunity is essential for disease control. Because Epstein-Barr Virus (EBV)-specific T cells have been highly successful in treating or preventing EBV-associated tumors, we hypothesized that the development of a manufacturing platform for HPV-specific T cells from healthy donors could be used in a third-party setting to treat patients with high-risk/relapsed HPV-associated cancers...

BACKGROUND: This study presents oncologic outcomes after transoral robotic surgery (TORS) ± adjuvant therapy for oropharyngeal squamous cell carcinoma (SCC). METHODS: Three hundred fourteen patients undergoing TORS ± adjuvant therapy for oropharyngeal SCC from May 1, 2007, to May 31, 2015, are analyzed. RESULTS: Median follow-up was 3.3 years (interquartile range [IQR] 1.8-5.3 years; range 1 day to 9.3 years). Estimated locoregional recurrence-free survival, distant metastasis-free survival (DMFS), overall survival (OS), and cancer-specific survival (CSS) rates (95% confidence interval [CI] number still at risk) at 5 years after surgery were 92% (88-95; 92), 90% (86-94; 92), 86% (82-92; 98), and 94% (91-97; 98), respectively...

An estimated 8200 men and women in the United States will receive a diagnosis of squamous cell carcinoma of the anal canal (SCCA) in 2017. Although SCCA is rare, accounting for 2.6% of gastrointestinal cancers, its incidence rate has been steadily increasing over the last few decades in the United States and around the world. More than 90% of cases of SCCA occur in the context of prior human papillomavirus (HPV) infection. To date, preventive vaccinations against HPV remain markedly underutilized. Most patients who have SCCA present with locoregional disease that is cured with chemoradiation...

We have developed a new human papillomavirus (HPV) assay using the uniplex E6/E7 polymerase chain reaction (PCR) method, which is able to detect E6 and E7 genes in 39 HPV types. We validated the assay for sensitivity and specificity using cloned HPV DNA and clinical samples. A comparative study using Genosearch-31 (GS-31) to determine HPV genotypes in clinical samples was also performed. E6 or E7 genes, measured by uniplex E6/E7 PCR, were detectable in 15 low-risk (HPV-6, -11, -40, -42, -44, -54, -55, -61, -62, -71, -74, -81, -84, -89, -90), 11 intermediate-risk (HPV-26, -30, -34, -53, -66, -67, -69, -70, -73, -82, -85), and 13 high-risk (HR) HPV types...

HPV-positive head and neck squamous cell carcinoma (HNSCC) is increasingly frequent. Management is particularly debated in the case of post-surgical high-risk features, i.e., positive surgical margins and extracapsular spread (ECS). In this increasingly complex emerging framework of HNSCC treatment, representative pre-clinical models are needed to support future clinical trials and advances in personalized medicine. Here, we present an immunocompetent mouse model based on the implantation of mouse tonsil epithelial HPV16-E6/E7-expressing cancer cells into the submental region of the floor-of-the-mouth...

High numbers of mast cells populate the stroma of many types of neoplasms, including human papilloma virus-induced benign and malignant tumors in man and mouse. Equipped with numerous pattern recognition receptors and capable of executing important pro-inflammatory responses, mast cells are considered innate sentinels that significantly impact tumor biology. Mast cells were reported to promote human papilloma virus (HPV)-induced epithelial hyperproliferation and neo-angiogenesis in an HPV-driven mouse model of skin cancer...

The staging of oropharyngeal squamous cell carcinoma has undergone key changes in the eighth edition of the American Joint Committee on Cancer Staging Manual, set to take effect January 1, 2018. The most significant change relates to the development of a novel staging system for human papillomavirus (HPV)-associated oropharyngeal squamous cell carcinomas, distinct from that for non-HPV-associated squamous cell carcinomas of the oropharynx. We describe the revised staging parameters and the rationale in support of the changes...

Head and neck cancer (HNC) remains the sixth most common malignancy worldwide and survival upon recurrence and/or metastasis remains poor. HNSCC has traditionally been associated with alcohol and nicotine use, but more recently the Human Papilloma Virus (HPV) has emerged as a favorable prognostic risk factor for oropharyngeal HNSCC. However, further stratification with additional biomarkers to predict patient outcome continues to be essential. One candidate biomarker is the DEK oncogenic protein, which was previously detected in the urine of patients with bladder cancer and is known to be secreted by immune cells such as macrophages...

Objective: Cervical cancer is one of the most common cancers among women all over the world, and main cause is persistent infection with high risk human papillomavirus (HPV) strains. It has been reported that the distribution and prevalence of HPV types varies by geographical region, so that this is important for prevention by type-specific vaccines. The aim of current study was to determine the genotype distribution of HPV using the INNO-LiPA genotyping assay in Zanjan province, North West Iran. Methods: A total of 112 formalin-fixed paraffin embedded (FFPE) tissue samples from cases of low-grade intraepithelial lesion (LSIL), high-grade intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were collected...

At present, advanced stage human Papillomavirus (HPV) negative and positive head and neck squamous cell carcinoma (HNSCC) are treated by intense multimodal therapy that includes radiochemotherapy, which are associated with relevant side effects. Patients with HPV positive tumors possess a far better prognosis than those with HPV negative cancers. Therefore, new therapeutic strategies are needed to improve the outcome especially of the latter one as well as quality of life for all HNSCC patients. Here we tested whether roscovitine, an inhibitor of cyclin-dependent kinases (CDKs), which hereby also blocks homologous recombination (HR), can be used to enhance the radiation sensitivity of HNSCC cell lines...
