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: Recently, associations of the human papillomavirus (HPV) with head and neck cancer have become well established. Of particular concern, the severity and pathological outcomes of squamous cell carcinomas are remarkably affected by the genotypes of HPV present in such lesions. This study was conducted to investigate the occurrence of HPV genotypes, particularly high risk 16 and 18, among oral and laryngeal squamous cell carcinomas in Jordan. Methods: During the period of May 2015 to March 2016, we evaluated a total of 108 paraffin-embedded tissue samples, histologically confirmed as SCC, of both oral and laryngeal tumors for the presence of HPV DNA...

Many aspects of the HPV life cycle have been characterized in cervical cell lines (W12, CIN612) and in HPV immortalized primary foreskin keratinocytes. There is now an epidemic of HPV positive oropharyngeal cancers (HPV16 is responsible for 80-90% of these); therefore increased understanding of the HPV16 life cycle in oral keratinocytes is a priority. To date there have been limited reports characterizing the HPV16 life cycle in oral keratinocytes. Using TERT immortalized "normal" oral keratinocytes (NOKs) we generated clonal cell lines maintaining the HPV16 genome as an episome, NOKs+HPV16...

BACKGROUND: Our next generation sequencing (NGS)-based human papillomavirus (HPV) genotyping assay showed a high degree of concordance with the Roche Linear Array (LA) with as little as 1.25 ng formalin-fixed paraffin-embedded-derived genomic DNA in head and neck and cervical cancer samples. This sensitive genotyping assay uses barcoded HPV PCR broad-spectrum general primers 5+/6+ (BSGP)5+/6+ applicable to population studies, but it's diagnostic performance has not been tested in cases with multiple concurrent HPV infections...

BACKGROUND: Head and neck cancer of unknown primary (HNCUP) is rare and prospective studies are lacking. The impact of different prognostic factors such as age and N stage is not completely known, the optimal treatment is not yet established, and the reported survival rates vary. In the last decade, human papilloma virus (HPV) has been identified as a common cause of and important prognostic factor in oropharyngeal cancer, and there is now growing interest in the importance of HPV for HNCUP...

BACKGROUND: Human papillomavirus (HPV)-related cancers have been associated with different demographic profiles and disease characteristics than HPV-unrelated cancers in head and neck patients, but distress and other symptoms have not been compared. The aim of this study was to assess whether distress levels, fatigue, pain, anxiety, depression, and common psychological and practical problems differ between head and neck cancer patients with HPV-related vs. HPV-unrelated carcinomas (using oropharyngeal carcinoma (OPC) and non-OPC cancers as surrogates for HPV status)...

Background: Basaloid squamous cell carcinoma (BSCC) is a rare variant of squamous cell carcinoma with distinct pathologic characteristics. The histogenesis of BSCC is not fully understood, and the cancer has been suggested to originate from a totipotent primitive cell in the basal cell layer of the surface epithelium or in the proximal duct of secretory glands. Materials and Methods: Twenty-six cases of head and neck BSCC from Asan Medical Center, Seoul, Korea, reported during a 14-year-period were subclassified into basal, ductal, and mixed subtypes according to the expression of basal (cytokeratin [CK] 5/6, p63) or ductal markers (CK7, CK8/18)...

Immune responses to the facultative intracellular bacterium Listeria monocytogenes (Lm) are robust and well characterized. Utilized for decades as a model of host-disease immunology, Lm is well suited for use as an immunotherapeutic bacterial vector for the delivery of foreign antigen. Genetic modification of Lm has been undertaken to create an attenuated organism that is deficient in its master transcriptional regulator, protein-related factor A, and incorporates a truncated, nonhemolytic version of the listeriolysin O (LLO) molecule to ensure its adjuvant properties while also preventing escape of the live organism from the phagolysosome...

Transoral surgery (TOS) is a novel technology whose adoption is expanding in the United States and other countries. TOS offers the possibility of a minimally invasive surgical approach to head and neck cancers. Its most frequent application has been in oropharyngeal cancers (OPC), of which most are associated with human papillomavirus (HPV). For HPV-associated OPC, where high response and survival rates are expected, deintensification of standard therapy is a major area of clinical research. In HPV-OPC, traditional pathologic risk factors indicating a need for adjuvant radiation or chemoradiation may not apply as strongly...

The composition of tumor-infiltrating lymphocytes (TIL) reflects biology and immunogenicity of cancer. Here, we characterize T-cell subsets and expression of immune checkpoint molecules in head and neck squamous cell carcinoma (HNSCC). We analyzed TIL subsets in primary tumors (n = 34), blood (peripheral blood mononuclear cells (PBMC); n = 34) and non-cancerous mucosa (n = 7) of 34 treatment-naïve HNSCC patients and PBMC of 15 healthy controls. Flow cytometry analyses revealed a highly variable T-cell infiltration mainly of an effector memory phenotype (CD45RA-/CCR7-)...

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...

Human papillomavirus (HPV) infection, widely known as the necessary cause of cervical cancer, has been established as a major etiologic factor for head and neck cancer (HNC). HIV-infected individuals are at higher risk of HPV-associated cancers than the general population. We describe a 45-year-old man with HIV and HPV coinfection, who presented progressively enlarging verrucous neoformations of the lips. The final diagnosis of verrucous carcinoma was delayed. Early detection of HPV lesions in oral mucosa and HPV screening activities could be important in improving the diagnostic sensitivity for the HIV-infected patients with oral cancer...

BACKGROUND: Currently, positive surgical margins in head and neck cancer are considered to be an indicator for postoperative chemoradiotherapy (CRT) over radiotherapy (RT) alone. However, there are less data regarding the impact of margin status on human papillomavirus (HPV)-related oropharyngeal squamous cell carcinoma (SCC). METHODS: We performed a retrospective review of 55 patients with oropharyngeal SCC undergoing primary surgical treatment. The impact of margin status on disease-specific survival (DSS) was studied according to p16 status...

The main purpose of the TNM system is to provide an anatomic-based classification to adequately depict cancer prognosis. Accurate cancer staging is important for treatment selection and outcome prediction, research design, and cancer control activities. To maintain clinical relevance, periodical updates to TNM are necessary. The recently published 8th edition TNM classification institutes the following changes to the staging of head and neck (excluding thyroid cancer): new stage classifications [HPV-related oropharyngeal cancer (HPV+ OPC) and soft tissue sarcoma of the head and neck (HN-STS)] and modification of T and N categories [T and N categories for nasopharyngeal cancer (NPC), T categories for oral cavity squamous cell carcinomas (OSCC), N categories for non-viral related head and neck cancer and unknown primary (CUP), and T categories for head and neck cutaneous carcinoma]...

Concurrent chemoradiotherapy (CRT) with high-dose (100 mg/m(2)), single-agent cisplatin is considered the standard of care for locoregionally advanced head and neck cancer (LAHNC). Poor compliance often due to significant treatment-related toxicities observed during CRT regimen has stimulated research efforts to examine for evidence of the optimal cumulative cisplatin dose and schedule. The findings from this systematic literature review demonstrate that there are insufficient prospective, randomized controlled data to determine the optimal total dose (and schedule) of cisplatin to administer concomitantly with radiotherapy in the treatment of LAHNC...
