Cancer oropharynx

Xiaotian Wu, Joseph A Paydarfar, Ryan J Halter
For a variety of head and neck cancers, specifically those of the oropharynx, larynx, and hypopharynx, minimally invasive trans-oral approaches have been developed to reduce perioperative and long-term morbidity. However, in trans-oral surgical approaches anatomical deformation due to instrumentation, specifically placement of laryngoscopes and retractors, present a significant challenge for surgeons relying on preoperative imaging to resect tumors to negative margins. Quantifying the deformation due to instrumentation is needed in order to develop predictive models of operative deformation...

BACKGROUND: Human papillomavirus (HPV) prevalence in oropharynx squamous cell carcinoma (OPSCC) is on the rise. HPV-linked OPSCCs represent a distinct clinical entity with a better treatment response and patient survival compared to tumors not linked to HPV. An emerging role in treatment response has been attributed to immune cell infiltration in human tumors. In this study, we investigated immune cell infiltration in human SCC of the head and neck region and its relation to overall survival after treatment with surgery (with or without radiotherapy) or concomitant chemo (or cetuximab)-radiotherapy...

PURPOSE: Transforming growth factor-β1 (TGF-β1) plays a critical role in inflammation and immune responses and treatment response and survival. TGF-β1 variants may affect its expression level or functional efficiency, thus modifying tumor status and survival in HPV-positive squamous cell carcinoma of the oropharynx (SCCOP). EXPERIMENTAL DESIGN: We determined tumor HPV16 status and genotyped three TGF-β1 polymorphisms in 564 incident SCCOP patients treated with radiotherapy or chemoradiation...

In addition to tobacco and alcohol consumption, the two main risk factors for oral squamous cell carcinoma (OSCC), recent studies have revealed infections with human papilloma virus (HPV) as an additional risk factor for OSCC development. In the field of head and neck malignancies, the prevalence of HPV infections in oropharyngeal cancer (OC) ranges in different studies up to 84%. While HPV infection is discussed as an independent risk factor in this region, its distinguished role in carcinogenesis of tumours localized to the oral cavity remains uncertain...

Human papillomavirus (HPV) type 16 is implicated in approximately 75% of head and neck squamous cell carcinomas (HNSCC) that arise in the oropharynx, where viral expression of the E6 and E7 oncoproteins promote cellular transformation, tumor growth, and maintenance. An important oncogenic signaling pathway activated by E6 and E7 is the phosphatidylinositol 3-kinase (PI3K) pathway, a key driver of carcinogenesis. The PI3K pathway is also activated by mutation or amplification of PIK3CA in over half of HPV(+) HNSCC...

A diagnosis of head and neck cancer (HNC) is typically followed by therapy that is associated with immediate and long-lasting toxic consequences. HNC patients' oral health needs may be complex and are best addressed in multidisciplinary collaborative teams including surgical, medical, and radiation oncologists, dental providers, nutrition, speech/swallow specialists, and physical therapists. Oral health maintenance also requires patient compliance and caregiver support. The role of dental providers begins prior to cancer diagnosis and continues through survivorship...

Kaposi's sarcoma herpesvirus (KSHV) is the etiological agent of Kaposi's sarcoma (KS). Both KSHV and HIV infections are endemic in Uganda, where KS is among the most common cancers in HIV-infected individuals. Recent studies examined the use of small RNAs as biomarkers of disease, including microRNAs (miRNAs), with viral and tumor-derived miRNAs being detected in exosomes from individuals with KSHV-associated malignancies. In the current study, the host and viral extracellular mature miRNA expression profiles were analyzed in blood of KS-negative individuals in Uganda, comparing those with or without KSHV detectable from the oropharynx...

The current study aimed to investigate the incidence and survival patterns of HNSCCs arising from different anatomic sites, potentially related (the oropharynx) or unrelated (the oral cavity, the larynx/hypopharynx) to HPV, to provide clues on possible growing impact of HPV in the epidemiology of HNSCC in Italy. Epidemiological data were retrieved from ten long-term Cancer Registries covering a population of 7.8 million inhabitants. Trends were described by means of the estimated annual percent change (APC) stratified by age and gender, and compared between HPV-related and HPV-unrelated anatomical sites...

In addition to traditional risk factors such as smoking, alcohol consumption and betel nut use, human papillomavirus (HPV) infection also plays a role in the development of head and neck squamous cell carcinomas (HNSCCs). Although among European countries the highest incidence and mortality rates of head and neck cancer types were recorded in Hungary, data regarding HPV prevalence in HNSCCs is scarce. We collected biopsy and saliva samples from patients diagnosed with HNSCC or oral potentially malignant disorders (OPMDs) and tested them for the presence of HPV using the PCR consensus primer set MY09/11 and the GP5+/6+ primer pair...
