NSUN2 is a tRNA methyltransferase and plays an important role in cell development via modifying RNA methylation. We aimed to evaluate the expression of NSUN2 and its prognostic value in HNSCC. Random-effects model of meta-analysis shows 1.99-folds (95% CI: 1.89-2.09) upregulation of NSUN2 expression in HNSCC versus normal tissues. Patients with high NSUN2 levels had approximately 22 months shorter overall survival, and had a higher mortality risk than those with low one (p-trend = 0.020). In conclusion, NSUN2 is a potential independent prognostic marker and may be a potential therapeutic target in HNSCC...

Head and neck squamous cell carcinoma (HNSCC) is an aggressive neoplasm with the properties of local recurrence and distant metastasis. Currently, cisplatin-based chemotherapy or concurrent radiochemotherapy is still the first choice or the treatment of advanced HNSCC. However, chemoresistance greatly limited the effectiveness of chemotherapy. Therefore, illustrating the mechanisms of chemoresistance is very important for the treatment of HNSCC. In this article, we summarize the molecular mechanisms of chemoresitance in HNSCC from the perspective of drug efflux, apoptosis, DNA damage and repair, epithelial mesenchymal transition and autophagy...

The standard first-line treatment in recurrent/metastatic head and neck squamous cell carcinoma combines Cisplatin, 5 Fluorouracil and Cetuximab, but many patients aren't eligible. We retrospectively evaluated the efficacy and the tolerability of Carboplatin and Paclitaxel in this indication, mostly in patients unfit to Cisplatin. Paclitaxel (80mg/m2) was administered at day 1, 8 and 15 and Carboplatin area under the curve 5 at day 1, repeated every 28 days, for 6 cycles. Carboplatin could be administered at area under the curve 2 at day 1, 8 and 15...

Introduction: Head and neck squamous cell carcinoma (HNSCC) treated by radio-chemotherapy have a significant local recurrence rate. It has been previously suggested that 18F-FDG PET could identify the high uptake areas that can be potential targets for dose boosting. The purpose of this study was to compare the location of initial hypermetabolic regions on baseline scans with the metabolic relapse sites after radio-chemotherapy in HNSCC. Results: The initial functional tumor volume was significantly higher for patients with proven local recurrence or residual disease (23...

In cancer cells,  BRAF  is frequently mutated at codon 600 (V600 ) leading to the replacement of valine amino acid with other amino acids. The current study was performed to assess the prevalence of  BRAF V600  mutation in Indian patients with head and neck squamous cell carcinoma (HNSCC). Among the patients, 27% were homozygous, and 71% were heterozygous for the mutation and only 2% showed a wild genotype. Since identification of  BRAF V600  mutation in cancer patients is used for selection of the therapeutic agents, this study shows that all Indian patients with HNSCCmust be screened for this mutation...

Head and neck cancer presents primarily as head and neck squamous cell carcinoma (HNSCC), a debilitating malignancy fraught with high morbidity, poor survival rates, and limited treatment options. Mounting evidence indicates that the Wnt/β-catenin signaling pathway plays important roles in the pathobiology of HNSCC. Wnt/β-catenin signaling affects multiple cellular processes that endow cancer cells with the ability to maintain and expand immature stem-like phenotypes, proliferate, extend survival, and acquire aggressive characteristics by adopting mesenchymal traits...

Head and neck cancers are the sixth most common cancers worldwide and an important cause of ill health.(1) Each year about 9000 cases are reported in the UK.(2) Survival is poor and despite advances in treatment, has not improved until recently.(3) The majority of head and neck cancers are squamous cell carcinomas, affecting the larynx, oropharynx and oral cavity. The aetiology is changing and this has implications for prevention and treatment. Twenty years ago, tobacco and alcohol consumption were considered to be the established risk factors and it was estimated that these risk factors accounted for about 75% of cases...

PURPOSE: The response rates of Head and Neck Squamous Cell Carcinoma (HNSCC) to checkpoint blockade are below 20%. We aim to develop a mechanism-based vaccine to prevent HNSCC immune escape. EXPERIMENTAL DESIGN: We performed RNA-Seq of sensitive and resistant HNSCC cells to discover central pathways promoting resistance to immune killing. Using biochemistry, animal models, HNSCC microarray and immune cell deconvolution, we assessed the role of SOX2 in inhibiting STING-type I interferon (IFN-I) signaling-mediated anti-tumor immunity...

Despite aggressive therapies, head and neck squamous cell carcinoma (HNSCC) is associated with a less than 50% 5-year survival rate. Late stage HNSCC frequently consists of up to 80% cancer-associated fibroblasts (CAF). We previously reported that CAF-secreted hepatocyte growth factor (HGF) facilitates HNSCC progression, however very little is known about the role of CAFs in HNSCC metabolism. Here we demonstrate that CAF-secreted HGF increases extracellular lactate levels in HNSCC via upregulation of glycolysis...

Cancer cells often secrete extracellular vesicles (EVs) that carry heat shock proteins (HSPs) with roles in tumor progression. Oral squamous cell carcinoma (OSCC) belongs to head and neck cancers (HNC) whose lymph-node-metastases often lead to poor prognosis. We have examined the EV proteome of OSCC cells and found abundant secretion of HSP90-enriched EVs in lymph-node-metastatic OSCC cells. Double knockdown of HSP90α and HSP90β, using small interfering RNA significantly reduced the survival of the metastatic OSCC cells, although single knockdown of each HSP90 was ineffective...

Head and neck squamous cell carcinoma (HNSCC) is the sixth common malignant tumors of whole body with a high incidence, which accounts for 90% of the head and neck malignant tumors. Previous studies have shown the risk factors, such as tobacco and alcohol, are related to the occurrence and development of HNSCC. However, recent studies have shown that the non-tobacco and non-alcohol related HNSCC increased year by year. At the same time, more and more studies have shown that HNSCC is related to the infection with human papilloma virus (HPV), and the occurrence and development of HPV-positive HNSCC has own characteristics in epidemiology, pathogenesis, treatment and prognosis...

BACKGROUND: The incidence of human papillomavirus-induced (HPV+) head and neck squamous cell carcinoma (HNSCC) i.e. especially oropharyngeal cancers (OPSCC) is increasing and a significant proportion of patients encounter disease progression. A simple and sensitive test to identify patients with progression is an unmet need. OBJECTIVE OF REVIEW: To systematically review the literature and carry out a meta-analysis of studies, investigated circulating HPV-DNA as a biomarker for disease progression in patients with HNSCC...

Head and neck squamous cell carcinoma (HNSCC) ranks among the top most common cancers with a poor prognosis. The mechanism of chemoresistance is still not well known. This study is to investigate the programmed death-ligand 1 (PD-L1) expression in HNSCC, and test the effect of lactoferricin B (LfcinB) on chemoresistance and its mechanism. We analyzed 510 HNSCC patients in TCGA database and investigated how CD274 expression was related to patient prognosis. PD-L1 was verified from HNSCC samples at local hospital with immunohistochemistry...

Head and neck squamous cell carcinomas (HNSCC) are in a group of cancers that are the most resistant to treatment. The survival rate of HNSCC patients has been still very low since last 20 years. The existence of relationship between oncogenic and surrounding cells is probably the reason for a poor response to treatment. Fibroblasts are an important element of tumor stroma which increases tumor cells ability to proliferate. Another highly resistance, tumorigenic and metastatic cell population in tumor microenvironment are cancer initiating cells (CICs)...

Sebaceous gland carcinoma (SGC) is a rare, but life-threatening condition with a predilection for the periocular region. Eyelid SGC can be broadly categorised into two subtypes, namely either nodular or pagetoid with the latter being more aggressive and requiring radical excision to save life. We have identified key altered microRNAs (miRNA) involved in SGC shared by both subtypes, hsa-miR-34a-5p and hsa-miR-16-5p. However, their gene targets BCL2 and MYC were differentially expressed with both overexpressed in pagetoid but unchanged in nodular suggesting different modes of action of these two miRNAs on BCL/MYC expression...
