Oral squamous cell carcinoma (OSCC) is one of the most common head and neck malignancies. Advanced stages of the disease are associated with poor survival, highlighting a need for new treatment modalities. We previously showed that the proinflammatory cytokine interleukin-18 (IL-18) has a tumor suppressive role in OSCC. Here, we investigated the effects of IL-18 on proliferation, migration, and invasion of OSCC cells ex vivo and in vitro , and in nude mouse xenografts. We report that expression of tankyrase 2 (TNKS2), β-catenin, and N-cadherin was higher in tumor cells than in normal mucosae, whereas the expression of IL-18 and E-cadherin was higher in normal than in tumor tissues...

BACKGROUND: Surgeons have developed various reconstructive techniques to minimize the rate of pharyngocutaneous fistula and optimize functional outcome after salvage laryngectomy or laryngopharyngectomy. METHODS: Multicenter retrospective review at 33 institutions of 486 patients with a history of squamous cell carcinoma (SCC) of the larynx or hypopharynx previously treated with primary chemoradiotherapy (CRT) who required salvage surgery. Outcomes evaluated were overall fistula rate, fistula requiring reoperation, and 12-month speech and swallowing function...

We assessed the use of peptides containing arginylglycylaspartic acid (RGD) that target integrin αvβ6 as a potential approach for a fluorescence-assisted intraoperative cytological assessment of bony resection margins (F-AICAB) in patients who had bone-infiltrating squamous cell carcinoma (SCC) of the head and neck. This was assessed to demarcate invasive carcinoma cells that stained for αvβ6. Specimens from bony resection margins (n=362) were defined as either malignant or benign according to the results of cytological and histological examinations...

SOX10 immunoexpression is increasingly recognized in salivary gland tumors, including but not limited to those with myoepithelial, serous acinar, and intercalated duct differentiation. However, SOX10 expression has not been extensively evaluated in other epithelial tumors that can mimic salivary origin. Basaloid squamous cell carcinoma (SCC) is a unique variant of SCC that shows morphologic overlap with several salivary tumors, including adenoid cystic carcinoma, basal cell adenocarcinoma, and myoepithelial carcinoma...

Squamous cell carcinoma (SCC) is the most common cancer of the head and neck region including-among others-laryngeal (LSCC) and hypopharyngeal (HSCC) subsites. LSCC/HSCC are heterogenous diseases with respect to patient outcome. Currently, tumor stage-based patient stratification is essential to predict prognosis and thus selection of the appropriate treatment modalities. In contrast, the prognostic impact of the current HSCC/LSCC grading system according to the WHO classification is limited. Recently, a novel grading system based on tumor budding activity (BA) and cell nest size (CNS) has been introduced for SCC in different anatomic regions of the upper aerodigestive tract...

Background: Oral and oropharyngeal squamous cell carcinomas (OSCC and OPSCC) represent the majority of head and neck squamous cell carcinomas (HNSCC). Human papillomavirus (HPV) is an important etiologic factor together with Epstein-Barr virus (EBV). Little is known on the prevalence of major herpesviruses [EBV, cytomegalovirus (CMV) and HHV-6, - 7 and - 8] in HNSCCs. Methods: Fifty-one formalin-fixed paraffin-embedded (FFPE) tissue samples taken at surgery (40 oropharyngeal, 11 oral) were analyzed for 40 HPV genotypes (20 high-risk types), EBV, CMV, HHV-6, - 7 and - 8 by quantitative PCR...

Treatment of head and neck cancer with curative intent consists of surgery and/or radiotherapy (RT) sometimes combined with adjuvant chemotherapy depending on the tumor site, extent, and histology. Herein, the authors review the role of RT in the management of head and neck mucosal squamous cell carcinoma (SCC). The authors focus on the outcomes of definitive RT and, depending on the primary site, postoperative RT. Unless otherwise specified, outcomes data cited are from the University of Florida.

Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cause of cancer mortality in the world. To improve the quality of diagnostics and patients' treatment, new and effective biomarkers are needed. Recent studies have shown that the expression level of different types of long non-coding RNAs (lncRNAs) is dysregulated in HNSCC and correlates with many biological processes. In this study, the response of lncRNAs in HNSCC cell lines after exposure to irradiation and cytotoxic drugs was examined...

Carcinoma of unknown primary (CUP) comprises approximately 1%-5% of all head and neck malignancies. Primary site detection rates for metastatic cervical squamous cell carcinoma (SCC) remain variable, with current diagnostic imaging unable to identify all tumours. Prevailing evidence suggests that most head and neck CUP are located in the oropharynx. Diagnostic surgical efforts have been directed at sampling the entire oropharynx. Present techniques that make this possible include transoral robotic surgery (TORS)...

Purpose: Basaloid squamous cell carcinoma (BSCC) is a rare, high-grade variant of squamous cell carcinoma (SCC). Most published studies based on population-based datasets focus on prognostic differences between SCC and BSCC. Competing risk analyses for this disease have not been performed. We used Surveillance Epidemiology and End Results (SEER) data to calculate and model the cumulative incidence of death for patients with head and neck BSCC (HNBSCC) with competing risk approaches, and built a model to predict probability of cause-specific death for these patients...

TRIM29 (tripartite motif-containing protein 29) is a TRIM family protein that has been implicated in breast, colorectal, and pancreatic cancers. However, its role in stratified squamous epithelial cells and tumors has not been elucidated. Here we investigate the expression of TRIM29 in cutaneous head and neck squamous cell carcinomas (SCC) and its functions in the tumorigenesis of such cancers. TRIM29 expression was lower in malignant SCC lesions than in adjacent normal epithelial tissue or benign tumors. Lower expression of TRIM29 was associated with higher SCC invasiveness...

Metastasis to the thyroid gland is rare; furthermore, intrathyroid metastasis from head and neck squamous cell carcinoma (SCC) is very unusual, with only nine previously documented cases four from intrathyroid metastasis from nasopharyngeal carcinoma, two from oral cavity, one each from oropharynx, larynx, and parotid. The reported case series are unique in nature and illustrates the role of fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) and ultrasound-guided biopsy in diagnosing clinically occult isolated intrathyroidal metastasis, which helps in the best management for an isolated intrathyroid metastases...
