Metastases and tumor recurrence have a major prognostic impact in head and neck squamous cell carcinoma (HNSCC); however, cellular models that comprehensively characterize metastatic and recurrent HNSCC are lacking. To this end, we obtained genomic, transcriptomic and copy-number profiles of the UM-SCC cell line panel, encompassing patient-matched metastatic and recurrent cells. UM-SCC cells recapitulate the most prevalent genomic alterations described in HNSCC, featuring common TP53, PI3K, NOTCH, and Hippo pathway mutations...

Chemoradiotherapy has emerged as a gold standard in advanced squamous cell carcinoma of the head and neck (SCCHN). Because 50% of advanced stage patients relapse after nonsurgical primary treatment, the role of salvage surgery (SS) is critical because surgery is generally regarded as the best treatment option in patients with recurrent resectable SCCHN. Surgeons are increasingly confronted with considering operation among patients with significant effects of failed non-surgical primary treatment. Wide local excision to achieve clear margins must be balanced with the morbidity of the procedure, the functional consequences of organ mutilation, and the likelihood of success...

Head and neck squamous cell carcinoma (SCC) ranks 6th among the most frequently diagnosed carcinomas globally. Laryngeal carcinoma is quite common, and 95% of the cases are SCCs. Since the introduction of larynx-preserving surgery, induction chemotherapy (IC) has played a substantial role. The aim of IC is to shrink or downstage primary laryngeal carcinomas, increasing the chances of complete surgical removal, particularly in cases with advanced but potentially resectable lesions. The aim of the present study was to investigate the value of IC in patients with resectable laryngeal cancer...

MicroRNAs (miRNAs) are confirmed to be tumor promoters or suppressors in multiple squamous cell carcinomas (SCCs). miR-99a-5p has been demonstrated to be downregulated in cancerous tissues, but its functional role in head and neck SCC (HNSCC) and its mechanism of action have not been fully elucidated. Here, we studied the expression of miR-99a-5p in HNSCC and performed a clinical value assessment and then extracted mature expression data from The Cancer Genome Atlas (TCGA) and microarrays from Gene Expression Omnibus (GEO)...

EGFR overexpression is associated with squamous cell carcinoma development. Altered endocytosis and polarization of receptor tyrosine kinases, including EGFR, affect migration and invasion in 3D culture. These studies have been completed via genetic sequencing, cell line or 3D in vitro and in vivo murine models. Here we describe an imaging method that allows ex-vivo examination of ligand-induced endocytosis of EGFR in non-dissociated human tumours. We analyzed sets of tumour samples from advanced cutaneous squamous cell carcinoma and Head and Neck squamous cell carcinoma, actinic keratosis, intra-epidermal carcinoma and cutaneous squamous cell carcinoma...

Programmed death-ligand 1 (PD-L1) expression by tumor cells is a mechanism for downregulation of antitumor T cell responses and is a target for immunotherapy in various cancers. PD-L1 status as a predictor of treatment response has led to the development of multiple platforms with different reference cutoffs. We studied 128 cases of genitourinary and head/neck carcinomas, aiming to assess the frequency of PD-L1 positivity, interobserver reliability of PD-L1 interpretation and the concordance of PD-L1 scoring between small samples from tissue microarray (TMA) and whole sections (WS) using SP263 and SP142 clones...

Background: Squamous Cell Carcinoma (SCC) is a type of cancer that is often found in oral cavity and areas of the head and neck. Viruses are major etiological factors through production of factors that can disturb proliferation and apoptosis regulators such as p53i, c-myc and bcl-2. This study aimed to determine the molecular grading of oral squamous cell carcinoma (OSCCs) infected with the Epstein-Barr Virus (EBV). Methods: Twenty-seven OSCC patients underwent biopsy to detect EBV infection through in situ hybridization for RNA EBV (EBER) and immunohistochemical analysis of latent membrane protein-1 (LMP-1) and EBV nuclear antigen-1 (EBNA-1)...

Metastasis to the thyroid is uncommon. Mostly, they are tumors that originate in the lung or head or neck. Metastases from breast or kidney carcinomas and metastatic melanoma have also been reported. Autotransplantation of benign thyroid tissue is a surgical procedure designed to achieve normal thyroid hormonal status following surgery. Metastasis into autotransplanted thyroid tissue has not been reported earlier. We report a case of squamous cell carcinoma (SCC) metastatic to autotrasplanted thyroid diagnosed on fine-needle aspiration...

TRF2 is a telomere binding protein, a component of the shelterin complex that plays a major role in maintaining the integrity of the genome. TRF2 is over-expressed in a number of human cancers including Head and Neck cancer and might play a key role in tumor initiation and development. p38 MAPK signaling pathway is strongly activated in response to various environmental and cellular stresses and thus overexpressed in most of the Head and Neck cancer cases. In this study, we investigated potential interactions of TRF2 with p38 in HNSCC cells and patient samples...

The purpose of this study was to evaluate the anti-head and neck squamous cell carcinoma (anti-HNSCC) cell activity by C6 ceramide and multikinase inhibitor PKC412. Experiments were performed on HNSCC cell lines (SQ20B and SCC-9) and primary human oral carcinoma cells. Results showed that PKC412 inhibited HNSCC cell proliferation without provoking apoptosis activation. Cotreatment of C6 ceramide significantly augmented PKC412-induced lethality in HNSCC cells. PKC412 decreased Akt-mammalian target of rapamycin (mTOR) activation in HNSCC cells, facilitated with cotreatment of C6 ceramide...

BACKGROUND: The incidence of non-melanoma skin cancer (NMSC) of the head and neck is increasing among older adults where it is credited to have a poorer prognosis also because the radicality of the surgery is often missed for a too conservative approach. An assessment of the amount of tumor regrowth and its prognostic consequences, in patients with surgical margins close or involved and older than 75 years, seems thus worth to be pursued in order to provide the best therapeutic strategy...
