Human papillomavirus (HPV)-mediated cervical carcinogenesis represents a well analyzed model of viral implication in epithelial malignant transformation. Mechanisms of high risk (HR) HPV-related infection seem to demonstrate a similar action regarding its implication in head and neck (HN) carcinomas, predominantly in squamous cell carcinoma (SCC) histological type. The prevalence of HR HPV subtypes - mainly HPV16 - is characterized by a broad geographic heterogeneity. Furthermore, HPV-associated HNSCCs demonstrate differences regarding sexual, molecular, epidemiological, and prognostic features compared to alcohol and tobacco dependent ones...

c-Jun activation domain-binding protein-1 (Jab1) is a multifunctional protein involved in cell proliferation and apoptosis, DNA damage and repair and genome stability. In a number of types of human carcinoma, the abnormal expression of Jab1 is associated with poor prognosis, suggesting that Jab1 serves a vital function in tumorigenesis. However, the functional effects and the underlying molecular mechanisms of Jab1 in laryngeal squamous cell carcinoma (LSCC) progression remain poorly understood. The results of the present study demonstrate that downregulating Jab1 expression promotes LSCC apoptosis while inhibiting the proliferation of LSCC cells...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

PURPOSE: This study aimed to determine whether intravenous contrast-enhanced dual-phase fluorine-18--fluorodeoxyglucose (F-FDG) PET/CT scans provide additional diagnostic information compared with the MRI/CT in patients with laryngeal carcinoma during the initial staging. PATIENTS AND METHODS: Forty-five consecutive patients (44 men, one woman; mean age±SD, 67.0±9.0 years, range: 45-80 years) with carcinoma of the larynx who had MRI/CT and intravenous contrast-enhanced PET/CT were enrolled...

Laryngeal carcinoma is a kind of head and neck carcinoma with high incidence and mortality. Chemotherapy treatments ofhuman laryngeal carcinoma may fail due to the development of chemo-resistance. Tissue inhibitor of metalloproteinases 3 (TIMP3) has been shown to be implicated in a number of pathological processes typical for cancer. The present study aims to investigate the involvement of TIMP-3 in chemo-resistance of laryngeal carcinoma. We showed that TIMP3 expression was significantly decreased in chemo-resistant laryngeal carcinoma tissues compared with chemo-sensitivity tissues...

BACKGROUND: Patients suffering from squamous cell carcinoma of the larynx (LSCC) with lymphatic metastasis have a relatively poor prognosis and often require radical therapeutic management. The mechanisms which drive metastasis to the lymph nodes are largely unknown but may be promoted by a pro-angiogenic tumor microenvironment. In this study, we examined whether the number of microvessels and the expression level of vascular endothelial growth factor (VEGF) in the primary tumor are correlated with the degree of lymph node metastasis (N-stage), tumor staging (T) and survival time in LSCC patients...

BACKGROUND: It is still unclear that dissection of recurrent laryngeal nerve nodes is mandatory in patients with cT1 middle or lower thoracic esophageal squamous cell carcinoma when the nodes are negative in preoperative staging work-up. We aimed to evaluate the feasibility of near-infrared image-guided lymphatic mapping of bilateral recurrent laryngeal nerve nodes. METHODS: The day before surgery, we injected indocyanine green (ICG) into submucosal layer by endoscopy...

AIM: We sought to determine the function of miR-181a/GATA6 pathway in the progression of laryngeal squamous cell carcinoma (LSCC). MATERIALS & METHODS: The expression of miR-181a and GATA6 were detected using quantitative real-time-PCR and western blotting in 127 LSCC samples and 32 corresponding control mucosa tissues. Cell death, migration and apoptosis were measured in Hep-2 cells using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT), Transwell migration assay and apoptosis assay, respectively...

AIM: In this study, we investigated the role of Y-box binding protein-1 (YB-1), c-Myb and miR-155 in human laryngeal squamous cell carcinoma (LSCC) progression. MATERIALS & METHODS: Quantitative real-time PCR, western blot, MTT and Transwell were conducted to determine the expression and function of YB-1/miR-155 pathway. Univariate and multivariate analyses were used to determine the prognostic factors. RESULTS: Expression of YB-1, c-Myb and miR-155 was higher in LSCC tissues...

Objective: The aim of this study was to investigate the effect of the Akt inhibitor Src-homology 5 (SH-5) on the proliferation and apoptosis of laryngeal squamous cell carcinoma cells (LSCC; Hep-2 cells) and to elucidate the possible mechanisms of such effects. Materials and Methods: Hep-2 cells were treated with different concentrations of the Akt inhibitor SH-5. The inhibitory effect of SH-5 on cell proliferation was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, whereas apoptosis was detected by flow cytometric based on Annexin V/propidium iodide (PI) staining...

Verruca vulgaris is a common skin lesion that is associated with human papilloma virus and is observed on the surface of skin. Verruca vulgaris is rarely seen in mucosal membranes. Atypical locations may be confused with verrucous carcinoma. The incidence of laryngeal verruca vulgaris has not yet been reported in the literature. Differential diagnoses in histopathological examinations include keratosis, squamous papilloma, verrucous hyperplasia, and verrucous carcinoma. Distinguishing disease from verrucous carcinoma is particularly important because the treatment approach can be altered...

Long noncoding RNA HOXA11 antisense RNA (HOXA11-AS) is involved in tumorigenesis and development of some human cancers. However, the role of HOXA11-AS in human laryngeal squamous cell cancer (LSCC) is yet unclear. In this study, we firstly investigated the expression of HOXA11-AS in LSCC. Microarray and qRT-PCR showed that the level of HOXA11-AS was significantly higher in LSCC than that in the corresponding adjacent non-neoplastic tissues. ISH revealed that HOXA11-AS was strongly expressed in the nucleus and closely related to the T grade, neck nodal metastasis, and clinical stage...

PURPOSE: Programmed cell death 4 (PDCD4) is decreased in many malignant tumors. Epithelial mesenchymal Transition (EMT) endows tumor cells invasive and metastatic properties. Few studies have elucidated the role of PDCD4 in the regulation of EMT during laryngeal carcinoma. METHODS: Using laryngeal carcinoma tissues, the relationship between PDCD4 and EMT-associated proteins E-cadherin and N-cadherin was examined. Gene manipulation was utilized to define the regulatory capacity of PDCD4...

OBJECTIVES/HYPOTHESIS: To characterize health burden and determine the associated level of equality of laryngeal carcinoma (LC) burden at a global level. METHODS: One hundred eighty-four countries were organized by socioeconomic status using Human Development Index (HDI) categorizations provided by the United Nations Development Program. Disability-adjusted life years (DALYs), obtained from The Global Health Data Exchange, were calculated and compared between each HDI category for the period from 1990 to 2015...

BACKGROUND: The lack of standardized treatment is problematic in laser surgery for laryngeal cancer, and may result in an increased recurrence rate. This study analyzed the prognosis of early laryngeal carcinoma after different types of cordectomy with laser surgery. METHODS: A cohort of 818 patients with stage Tis or T1 primary early glottic squamous cell carcinoma treated with CO2 laser surgery was retrospectively analyzed. RESULTS: Of the 818 patients, According to the Kaplan-Meier method, the rate of 5-year overall survival was 92...
