Head and neck squamous cell carcinoma (HNSCC) is often diagnosed at advanced stages, incurring significant high mortality and morbidity. This review explored the risk stratification of miRNAs, and investigated the impact of miRNA networking in HNSCC prognostication. We performed a meta-analysis and a systematic literature search on online databases for papers published prior to December 1, 2016. The list of miRNAs was uploaded to MetacoreTM to construct a protein-protein interaction network, which was used to identify targets of the miRNAs and potential drugs...

OBJECTIVE: The purpose of this article is to summarize the evidence for the value of PET/CT for the management of patients with head and neck squamous cell cancer and suggest best clinical practices. CONCLUSION: FDG PET/CT is a valuable imaging tool for identifying unknown primary tumors in patients with known cervical node metastases leading to management change and is the standard of care for the initial staging of stage III and IV head and neck squamous cell carcinomas (HNSCCs), for assessing therapy response when performed at least 12 weeks after chemoradiation therapy, and for avoiding unnecessary planned neck dissection...

Head and neck squamous cell carcinoma is typically characterized by a high incidence of local recurrences. It has been extensively shown that mucosa from head and neck squamous cell carcinoma patients carries both genetic and gene expression alterations, which are mostly attributable to major etiologic agents of head and neck squamous cell carcinoma. We previously identified a signature of microRNAs (miRNAs) whose high expression in tumors is predictive of recurrence. Here, we investigated whether the deregulation of miRNA expression in the tumor-surrounding mucosa is correlated to disease recurrence...

DNA mismatch repair system (DNA MMR) is a crucial genetic mechanism for DNA homeostasis in prokaryotic and eukaryotic cells. During DNA replication and also recombination, point intra-nucleotide errors including base deletion, insertion, and mis-incorporation happen. These raised abnormalities in the newly synthesized DNA strand could affect negatively the stability of the molecule and the function of the corresponding genes. DNA MMR proteins prevent these errors by recognizing and repairing them, securing directly the normal anatomy of the DNA double strand and indirectly the expression of the genes...

BACKGROUND: Jeju Island is geographically and socioeconomically distinct from the mainland of South Korea. Thus, the presentation and management of non-melanocytic skin cancers (NMSC) of the head and neck may differ from those in other regions of the country. We compared the clinical characteristics and treatment modalities of NMSC on Jeju Island with the findings of similar regional studies. METHODS: Patient data, including age, sex, diagnosis, tumor site, treatment, and recurrence, were obtained from the medical and pathology records of patients diagnosed with NMSC between January 2010 and June 2015...

BACKGROUND: Acetylsalicylic acid (aspirin) and non-steroidal anti-inflammatory drugs (NSAIDs) have been associated with reduced risks for certain human cancers. However, the effects of aspirin and NSAIDs on head and neck squamous cell carcinoma (HNSCC) remain controversial, and the prognostic effects of these drugs in patients with HNSCC are largely unknown. This study examined the clinical impact of aspirin and NSAIDs on disease recurrence and survival in patients with HNSCC. METHODS: This study analysed a cohort of 1392 consecutive patients who received definitive treatment for previously untreated HNSCC at our tertiary referral center...

Head and neck squamous cell carcinoma (HNSCC) accounts for 3-5% of all tumor types and remains an unmet medical need with only two targeted therapies approved to date. ErbB3 (HER3), the kinase-impaired member of the EGFR/ErbB family, has been implicated as a disease driver in a number of solid tumors, including a subset of HNSCC. Here we show that the molecular components required for ErbB3 activation, including its ligand neuregulin-1 (NRG1), are highly prevalent in HNSCC and that HER2, but not EGFR, is the major activating ErbB3 kinase partner...

PURPOSE: Local immunosuppression remains a critical problem that limits clinically meaningful response to checkpoint inhibition in patients with head and neck cancer. Here, we assessed the impact of MDSC elimination on responses to CTLA-4 checkpoint inhibition. EXPERIMENTAL DESIGN: Murine syngeneic carcinoma immune infiltrates were characterized by flow cytometry. Granulocytic MDSCs (gMDSCs) were depleted and T-lymphocyte antigen-specific responses were measured...

MicroRNAs (miRs) participate in tumor growth and dissemination by regulating expression of various target genes. MiR-223-3p is suspected of being involved in head and neck squamous cell carcinoma (HNSCC) growth although its precise role has not been elucidated. In this study, we showed that miR-223-3p is present in biopsies of HNSCC patients and that its presence is correlated with high neutrophil infiltrate. We found that overexpression of miR-223-3p slightly increased proliferation of the CAL27 squamous carcinoma cell line both in vitro and in vivo...

Among the variants of squamous cell carcinoma (SCC) of the head and neck arising in mucosal surfaces, examples with sebaceous differentiation are exceedingly rare. We present a new case of SCC with sebaceous differentiation, developing in the larynx of a 64 year-old male, cigarette smoker and alcohol drinker. The tumor extended transglottically, metastasized to cervical lymph nodes, and killed the patient after 12 months. Comparing this case with four previously reported cases of SCC with sebaceous differentiation, two arising in the larynx and the other two in the adjacent pharynx, all five patients mostly shared the following features: appearance of the tumor in the seventh decade of life, heavy tobacco smoking, alcohol intake in three, surgery as mainstay treatment, tumor size between 2 and 4...

Xiongwen Ran, Kai Yang
Head and neck cancer (HNC) is a common malignant tumor, but traditional therapeutic methods have unsatisfactory curative effects and many complications occur. Hence, there is an urgent need to develop therapeutic methods that can elicit curative effects as well as low toxic and few side effects. With the development of cancer molecular biology and immunology, targeted therapy for immune checkpoints of programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) has shown enormous development prospects for HNC treatment...

Human myiasis is a parasitosis usually found in tropical and underdeveloped countries. It usually affects ulcerated lesions or devitalized tissues, developing after deposition of dipterous eggs. Patients with head and neck cancer are at risk to develop secondary myiasis. A representative percentage of those patients manifest with neglected and advanced tumors, usually in exposed areas and with necrotic tissues. Few case reports and small series constitute the available information about this parasitosis. Most studies have been conducted in patients with skin carcinomas, although myiasis has already been described in association with other head and neck malignancies...

FCGR2A-H131R and FCGR3A-V157F are single-nucleotide polymorphisms known to influence the outcome of patients treated with rituximab, cetuximab and trastuzumab. We investigated the impact of these polymorphisms on the clinical outcome of 103 patients with recurrent or metastatic squamous cell carcinoma of the head and neck treated with a platinum compound, fluorouracil and cetuximab as palliative first-line therapy. The survival of patients with FCGR2A-131H/H and/or FCGR3A-157V/V genotypes was significantly longer compared with patients carrying 131R and 157F alleles (median progression-free survival (PFS): 5...

Results from numerous studies suggest an important role for somatic copy number alterations (SCNAs) in cancer progression. Our work aimed to identify the drivers (oncogenes or tumor suppressor genes) that reside in recurrently aberrant genomic regions, including a large number of genes or non-coding genes, which remain a challenge for decoding the SCNAs involved in carcinogenesis. Here, we propose a new approach to comprehensively identify drivers, using 8740 cancer samples involving 18 cancer types from The Cancer Genome Atlas (TCGA)...
