The microbiome is fundamentally one of the most unique organs in the human body. Dysbiosis can result in critical inflammatory responses and result in pathogenesis contributing to neoplastic events. We used a pan-pathogen array technology (PathoChip) coupled with next-generation sequencing to establish microbial signatures unique to human oral and oropharyngeal squamous cell carcinomas (OCSCC/OPSCC). Signatures for DNA and RNA viruses including oncogenic viruses, gram positive and negative bacteria, fungi and parasites were detected...

The role of different types of human papillomavirus (HPV) in the development of oral and oropharyngeal papillomas remains unclear. High-risk HPV (HR-HPV) was shown to be involved in the pathogenesis of significant proportion of squamous cell carcinomas of the oropharynx. In this study, we hypothesized that in some oropharyngeal papillomas, low-risk HPV (LR-HPV) and HR-HPV infection could co-exist, similar to what is observed in genital warts, and thus contribute to the elevated risk of malignancy. To test this hypothesis, we used real-time PCR to assess the presence of HPV DNA of 16 types (2 LR-HPV and 14 HR-HPV), in 75 formalin-fixed and paraffin-embedded histopathological samples of oral and oropharyngeal papillomas and in 57 squamous cell carcinomas from the same regions...

High-risk (HR) human papillomavirus (HPV) is now recognised as the principal cause of the increasing incidence rates of oropharyngeal squamous cell carcinoma (OPSCC) in some parts of the world.The primary risk factor for developing HPV-related OPSCC is oral HPV-infection and the majority of oral HPV-infections are acquired by oral sex. Progression into a OPSCC includes persistent infection with evasion of immune response in the microenvironment, the activation of viral early genes (E6, E7) in basal epithelial cells, the deregulation of cell cycle and the accumulation of chromosomal instability...

There is a long-standing convention to irradiate the great majority of head and neck squamous cell carcinoma (HNSCC) electively to both sides of the neck, to reduce the theoretically increased risk of contralateral regional failure (cRF). With the currently available diagnostic imaging techniques this treatment paradigm means, in our opinion, an overtreatment in considerable proportion of these patients. From all the published studies (n = 11, with 1116 patients treated in total), the incidence of cRF in patients with oropharyngeal cancer treated to one side of the neck is 2...

BACKGROUND: It is unclear why human papillomavirus (HPV)-related head and neck squamous cell carcinoma (HNSCC) has improved clinical behavior compared to HPV-negative HNSCC. We sought to better characterize the immune microenvironment of tongue cancers by examining the CD3 and CD8 TIL pattern in HPV-positive and -negative tumors. METHODS: Histologic sections from 40 oral tongue and oropharyngeal cases were analyzed (n= 21 HPV DNA-positive, n= 19 HPV DNA-negative)...

BACKGROUND: Only a 5% improvement in overall survival to oral cancer has been achieved in the last 20 years. Almost half of all oral carcinomas are diagnosed at advanced stages essentially due to delay in the diagnosis. Objective of the review: to examine the relative length of the patient and primary care intervals in symptomatic oral cancer. TYPE OF REVIEW: Quantitative systematic review. SEARCH STRATEGY: ((oral cancer OR oral squamous cell carcinoma OR oropharyngeal cancer) AND (time interval OR diagnostic delay))...

The molecular association between human papilloma virus (HPV) and cell cycle-related (CCR) proteins is not fully understood in oropharyngeal squamous cell carcinoma (OPSCC). Herein, we examined the expression levels of CCRs in OPSCCs based on HPV status. In situ hybridization (ISH)- and polymerase chain reaction (PCR)-based assays were used to detect HPV status in 98 OPSCCs, and CCRs were detected by immunostaining. Of 98 tumors, 47 had HPV-positive tumors by either ISH- or PCR-based assays. Concordance analysis between ISH- and PCR-based tests showed a good agreement in OPSCC...

BACKGROUND: Transoral robotic-assisted surgery (TORS) is increasingly utilized in the treatment of oropharyngeal squamous cell carcinoma (OPSCC). Postoperative bleeding is a significant and potentially fatal complication of TORS. Prophylactic ligation of ipsilateral external carotid artery (ECA) branches is a recognized strategy to reduce postoperative bleeding risk. We examined the incidence and sequelae of postoperative oropharyngeal bleeding with and without routine ECA ligation. METHODS: OPSCC patients treated with TORS between 2010 and 2015 with minimum 30days follow up were included...

High-risk human papillomavirus (HPV)-related oropharyngeal squamous cell carcinomas have a more favorable prognosis than HPV-negative ones. p16 immunohistochemistry has been recommended as a prognostic test in clinical practice. Several p16 antibodies are available, and their performance has not been directly compared. We evaluated three commercially available p16 antibody clones (E6H4, JC8 and G175-405) utilizing 199 cases of oropharyngeal squamous cell carcinoma from a tissue microarray, read by three pathologists with three different cutoffs for positivity: any staining, >50% and >75%...

BACKGROUND: New cases of oropharyngeal squamous cell carcinoma (OPSCC) are routinely tested for HPV. HPV in saliva can be detected with PCR, but its clinical applicability in the context of OPSCC remains unknown. METHODS: Forty-six consecutive patients diagnosed with OPSCC had pre-treatment saliva specimens collected. PCR for HPV on saliva was compared to p16 IHC and HPV DNA in-situ hybridisation (ISH) on surgical biopsies. RESULTS: The sensitivity and specificity of saliva testing when compared to the reference test of p16 IHC and HPV DNA ISH was 72...

BACKGROUND: Osteoradionecrosis (ORN) of the mandible is a late toxicity affecting patients treated with radiotherapy for head and neck malignancies. To the authors' knowledge, ORN has no standardized grading system and its reporting is based on retrospective findings in heterogeneous patient populations. The rate of ORN in the era of intensity-modulated radiotherapy (IMRT) still is unknown. METHODS: The authors report the incidence of ORN from prospectively collected data regarding 1196 patients who were diagnosed with squamous cell carcinoma of the oropharynx and treated with curative-intent IMRT, with or without concomitant systemic treatment, from January 2005 to December 2014...

Tonsillar squamous cell carcinomas (TSCCs) are the most common human papillomavirus- (HPV-) associated oropharyngeal cancers with poor prognosis. Homeodomain-interacting protein kinase 2 (HIPK2) is a central regulator of p53, which participates in apoptosis during the DNA damage response. HIPK2 is involved in HPV-associated uterine cervical and cutaneous carcinogenesis through its binding of HPV E6, thereby preventing apoptosis and contributing to tumor progression. However, its clinical and prognostic significance in TSCC remains unclear...

Human papillomavirus (HPV) has been identified as the primary etiologic factor of cervical cancer, and subsets of anogenital and oropharyngeal cancers. HPV18 is the second most prevalent high-risk HPV type after HPV16. Furthermore, HPV18 is responsible for approximately 12% of cervical squamous cell carcinoma and 37% of cervical adenocarcinoma cases worldwide. In this study, we aimed to characterize the HPV18-E6-specific epitope and establish an HPV18 animal tumor model to evaluate the E6-specific immune response induced by our DNA vaccine...
