Oral cancer is the eleventh most common cancer globally, with well-established major risk factors of tobacco, areca nut, alcohol, and high-risk human papillomavirus (HR-HPV) types 16 and 18. HR-HPV16/18 are the etiologic agents of cervical cancers and a proportion of oropharyngeal cancers. HPV-associated oropharyngeal and oral cancers show better prognosis and response to therapy. However, the picture of HR-HPV16/18 and the clinical implications of oral cancers are not clear with the majority of reports combining oral cancer data with head and neck cancers...

BACKGROUND: Thirty-day hospital readmissions have become a measure of quality of care. Many readmissions enter through the emergency department. The purposes of this study were to determine the rate, risk factors, and costs of 30-day returns to the emergency department (30dEDRs) after head and neck surgery. METHODS: All adult patients undergoing head and neck surgery at the University of Florida from 2012 to 2014 were reviewed. Univariate and multivariate logistic regression analyses were performed to identify risk factors for 30dEDRs...

Head and neck cancers together (oral cavity, pharynx and larynx) are sixth commonest worldwide and are the commonest cancers in developing countries. The Cancer Project was started in Kheda/Anand, Gujarat, a harvest land of tobacco. The objective of this programme was to indoctrinate the most vulnerable and the least tended upon; the basics of head and neck cancers via the medium of their own kins. Voluntary village health workers were educated and trained to pick up the early signs of head and neck cancers...

Head and neck squamous cell carcinoma (HNSCC) has been found to be a complex group of malignancies characterized by their profound immunosuppression and high aggressiveness. In most cases of advanced HNSCC, treatment fails to obtain total cancer cure. Efforts are needed to develop new therapeutic approaches to improve HNSCC outcomes. In this light, T-cells "immune checkpoint" has attracted much attention in cancer immunotherapy. It has been broadly accepted that inhibitory T-cell immune checkpoints contribute to tumor immune escape through negative immune regulatory signals (cytotoxic T-lymphocyte-associated antigen 4 [CTLA-4], programmed cell death 1 [PD-1], B7-H3, and B7-H4, etc)...

INTRODUCTION: Growing evidence shows a causal role of high-risk humane papillomavirus (HPV) infections in the development of head and neck cancer. A recent case report shows two patients suffering from tonsillar cancer without any risk factors apart from their work as gynecologists doing laser ablations and loop electrosurgical excision procedures (LEEP). The aim of the present investigation is to evaluate whether surgical plume resulting from routine LEEPs of HSIL of the cervix uteri might be contaminated with the DNA of high-risk HPV...

Tumor cells frequently overexpress heat shock protein 70 (Hsp70) and present it on their cell surface, where it can be recognized by pre-activated NK cells. In this retrospective study the expression of Hsp70 was determined in relation to tumor-infiltrating CD56+ NK cells in formalin-fixed paraffin embedded (FFPE) tumor specimens of patients with SCCHN (N=145) as potential indicators for survival and disease recurrence. All patients received radical surgery and postoperative cisplatinum-based radiochemotherapy (RCT)...

The favorable features of high-risk human papillomavirus (HPV) in the head and neck are limited to those harboring transcriptionally-active HPV, which occur predominantly in the oropharynx (OP). Factors rendering the OP susceptible to HPV oncogenesis are largely unexplored. The role of cytokeratin 7 (CK7) in predisposition to HPV and cancer in the cervix has been evaluated. However, its significance in the H&N is unknown. CK7 immunohistochemistry was performed on a tissue microarray cohort of OP and non-oropharyngeal (NOP) squamous cell carcinomas (SCC) with known clinical follow-up and HPV E6/7 mRNA status...

PURPOSE: The microenvironment of head and neck squamous cell carcinomas (HNSCCs) is highly immunosuppressive. HNSCCs expressing elevated levels of PD-L1 have especially poor outcome. Exosomes that carry PD-L1 and suppress T-cell functions have been isolated from plasma of patients with HNSCC. The potential contributions of PD-L1+ exosomes to immune suppression and disease activity are evaluated. METHODS: Exosomes isolated from plasma of 40 HNSCC patients by size exclusion chromatography were captured on beads using anti-CD63 Abs, stained for PD-1 and PD-L1 and analyzed by flow cytometry...

OBJECTIVE: Our recent studies have revealed that both strands of pre-miRNAs, the guide strand and the passenger strand, are involved in cancer pathogenesis. Analyses of miRNA expression signatures by RNA sequencing in head and neck squamous cell carcinoma (HNSCC) showed that both of the strands of pre-miR-150 (miR-150-5p and miR-150-3p) were significantly downregulated, and that these miRNAs acted as antitumor miRNAs in HNSCC cells. The aim of this study was to identify oncogenic genes in HNSCC cells that were regulated by miR-150-5p and miR-150-3p...

OBJECTIVE: Resection of posteriorly located oral squamous cell carcinomas (OSCCs) remains challenging for head and neck surgeons. However, several surgical techniques, such as lip and mandibular splitting, as well as submental "visor drop-down" of intraoral soft tissues, have been proposed for this purpose. Merrick et al. suggested that a pedicled genial drop-down surgical approach should be used to resect dorsally located OSCCs. Our study investigated patient outcomes following this surgical procedure, as no previous study has analyzed long-term follow-up data...

Galectin-1 is a hypoxia-regulated protein and a prognostic marker in head and neck squamous cell carcinomas (HNSCC). Here we assessed the ability of non-peptidic galectin-1 inhibitor OTX008 to improve tumor oxygenation levels via tumor vessel normalization as well as tumor growth inhibition in two human HNSCC tumor models, the human laryngeal squamous carcinoma SQ20B and the human epithelial type 2 HEp-2. Tumor-bearing mice were treated with OTX008, Anginex, or Avastin and oxygen levels were determined by fiber-optics and molecular marker pimonidazole binding...

PURPOSE OF REVIEW: The head and neck cancer (HNC) survivorship experience is unique among cancer populations. This review seeks to explore the HNC survivor experience associated with altered upper aerodigestive tract (UADT) function using principles of survivorship. RECENT FINDINGS: HNC survivors experience complex physical, functional, and psychosocial challenges related to UADT dysfunction. Interventions need to address all of these dimensions being mindful of the survivor experience...

Objective Many aggressive head and neck cancers contain 2 metabolically coupled tumor compartments: a glycolytic stromal compartment with low caveolin-1 (CAV1) and high monocarboxylate transporter 4 (MCT4) expression and a highly proliferative carcinoma cell compartment with high MCT1. Metabolites are shuttled by MCTs from stroma to carcinoma to fuel tumor growth. We studied the effect of carcinoma-fibroblast coinjection and metformin administration on a mouse model of head and neck squamous cell carcinoma...

Head and neck squamous cell carcinoma (HNSCC) is a highly morbid disease. Recent developments including Food and Drug Administration (FDA) approved molecular targeted agent's pembrolizumab and cetuximab show promise but did not improve the five-year survival which is currently less than 40%. The hepatocyte growth factor receptor; also known as mesenchymal-epithelial transition factor (c-Met) and its ligand hepatocyte growth factor (HGF) are overexpressed in head and neck squamous cell carcinoma (HNSCC); and regulates tumor progression and response to therapy...

PURPOSE: The CONDOR study showed that docetaxel/cisplatin/5-fluorouracil (TPF) followed by conventional radiotherapy with cisplatin 100 mg/m2 on days 1, 22, and 43 (cis100 + RT; n = 27)) versus accelerated radiotherapy with cisplatin weekly 40 mg/m2 (cis40 + ART; n = 29) in locally advanced head and neck cancer (LAHNC) patients was not feasible. Here, we report the analysis of health-related quality of life (HRQOL) of the patients entered in this study. METHODS: HRQOL was assessed at baseline, after two TPF, before start of chemoradiotherapy, and 1, 4, 8, 12, and 24 months after completion of chemoradiotherapy using the EORTC-QLQ-C30 and QLQ-H&N35 in 62 patients...

Checkpoint kinase inhibitors (CHKi) exhibit striking single agent activity in certain tumors, but the mechanisms accounting for hypersensitivity are poorly understood. We screened a panel of 49 established human head and neck squamous cell carcinoma (HNSCC) cell lines and report that nearly 20% are hypersensitive to CHKi monotherapy. Hypersensitive cells underwent early S-phase arrest at drug doses sufficient to inhibit greater than 90% of Chk1 activity. Reduced rate of DNA replication fork progression and chromosomal shattering were also observed, suggesting replication stress as a root causative factor in CHKi hypersensitivity...
